Solar Power Without Upfront Capital for Businesses, Farmers, and Industry
20–30% cheaper than grid power?
Logic Energy builds, finances, and operates a solar power system on your building’s roof—your company pays zero upfront capital and purchases the solar electricity at a fixed price of 11–13 cents/kWh instead of the current 16–18 cents/kWh for grid electricity (BDEW 10/2025), which is 20–30% cheaper. Fixed price for 20 years, no impact on the balance sheet, no maintenance obligation. At the end of the contract, you can choose between purchasing the system, dismantling it, or continuing the agreement. This model is known as On-Site PPA (Power Purchase Agreements) or solar contracting and has become an established component of the energy supply in Germany. The benefits: predictable costs, a fixed price for 20 years, and zero investment risk.
Why this solution makes financial sense right now
Electricity prices for businesses stood at 17.8 ct/kWh in 2025 and, according to the BDEW forecast, will remain at around 16 ct/kWh in 2026. At the same time, a well-planned rooftop PV system generates electricity at a cost of 5.7–12.0 ct/kWh (Fraunhofer ISE, July 2024). This gap between purchase and generation is the basis of the PPA principle: A specialized power generator handles the investment, construction, and operation—and passes on a significant portion of the cost savings to your company in the form of planning security. The advantages: zero investment risk, fixed costs, and balance sheet neutrality.
Germany is now the European leader in the number of power purchase agreements (PPAs) signed: 48 such agreements totaling 2.04 GW in 2024 (Pexapark European PPA Market Outlook 2025). The Solar Peak Act (effective February 25, 2025) makes power purchase agreements even more attractive because compensation is waived when exchange prices are negative. Those who make a decision today secure 20 years of fixed rates in an energy market that is moving precisely in this direction—a central project of the energy transition with clear advantages for commercial customers.
What does “solar power without an upfront investment” mean?
The principle works as follows: A service provider installs the solar system on your building’s roof and supplies the generated PV electricity at fixed, agreed-upon rates. Your company makes no investment, bears no technical risk, and receives affordable, predictable green electricity. Such PV systems can be implemented in various ways—for example, as an On-Site PPA (Power Purchase Agreement), in which your company uses the generated electricity directly without owning the system itself. This form of electricity supply is also known in technical jargon as solar contracting and offers clear advantages for both parties.
There are several ways to use green electricity from your own rooftop without investing in the purchase of a PV system yourself. In addition to the contracting model described here, there are also pure rental models (where you rent the system on a monthly basis and use the electricity yourself) as well as traditional bank financing through a loan. This article focuses on the PPA approach because it generally offers the most favorable terms and the lowest financial burden for companies with their own rooftop space. You can find a direct comparison of all four options in Section 10.
The business case: A PV system pays for itself over 20 years—but someone has to front the initial costs. Instead of your company tying up €500,000 to €1.5 million in capital for this investment, Logic Energy, as the system operator, handles the financing and all investment costs. In return, you purchase the PV electricity over the term of the agreement. Because the generation costs of a modern rooftop installation are significantly lower than the purchase prices, there is enough margin to benefit both parties: Your company saves 20–30%, Logic Energy generates a return and bears the risks. This option is available today for virtually any suitable commercial property.
Three terms are often used interchangeably: Solar contracting emphasizes the service aspect (construction and operation from a single source, including all products related to planning and operations management). On-site PPA emphasizes the delivery of electricity directly to your building. “PV without investment” is the marketing term for the same concept. All three describe the same basic structure—an established energy solution for small and medium-sized businesses.
Here’s how the PPA agreement works in five steps
Process: Roof inspection, contract signing, construction, electricity supply, final connection. Logic Energy handles planning, permitting, CAPEX, OPEX, maintenance, insurance, and monitoring. You provide the rooftop space and sign a 20-year electricity supply contract. Typical project timeline from signing to commissioning: four to nine months, depending on the size of the system and grid connection.
Step 1 — No-obligation roof inspection and cost-benefit analysis
Please provide your address, usable floor space, and annual electricity consumption (ideally your last twelve monthly utility bills). Within 48 hours, your company will receive a non-binding estimate: your customized price per kWh, the projected annual generation, your self-consumption rate, and the total savings over 20 years—including a clear breakdown of the benefits compared to your current rate plan.
Step 2 — Fixed-rate electricity supply contract
If the outcome is positive, a 20-year agreement will be signed. The purchase price per kWh is fixed in the contract for the entire term, usually with moderate inflation indexation applied to the agreed prices (typically 1.0–1.5% per annum). Also regulated in the contract: the use of the rooftop area via an easement (with land registry entry), the three exit options, and the transitional provisions in the event of a property sale.
Step 3 — Planning, Permitting, and Construction by Logic Energy
Logic Energy handles structural analysis, the grid connection application to the distribution system operator, permits, the procurement of modules and inverters, the entire installation process, and commissioning. As the project manager, Logic Energy bears the full cost of CAPEX (capital expenditures) and OPEX (operating expenses). There is no cash outflow for your company and no balance sheet entry—a key advantage over traditional financing solutions.
Step 4 — Electricity supply at a fixed purchase price
Electricity delivery begins once the system is commissioned. Your company pays a transparent monthly rate based on the actual number of kilowatt-hours consumed at the agreed-upon prices. Maintenance, cleaning, monitoring, insurance, and repairs are included. Your current utility provider remains responsible for the remaining electricity (nighttime, winter months, peak load)—rooftop generation typically covers 30–70% of your annual consumption.
Step 5 — After 20 years: Buy, cancel, or renew
At the end of the initial term, you have three options: purchase the system at its residual value and continue operating it at virtually no cost; request that Logic Energy dismantle it free of charge; or extend the operating agreement under significantly more favorable terms in line with current market rates. All three options are clearly outlined in the contract—there is no automatic renewal and no hidden renegotiation clauses.
What kind of savings are realistic? A 20–30% discount has been confirmed
The typical discount compared to industrial electricity prices is 20–30%. In numerical terms: With grid electricity at 16.0 ct/kWh (BDEW forecast for 2026) and typical on-site purchase prices of 11–13 ct/kWh, this results in a savings of 19–31%. The exact discount depends on roof size, consumption profile, location, and self-consumption rate—it is calculated individually for your company in the Roof Check. Direct subsidies are not necessary because the contractual solutions are self-financing through the price difference. Power Purchase Agreements have thus become a key tool that enables companies to make their electricity prices predictable in the long term.
The plausibility of this figure can be easily verified based on current electricity prices and costs:
| cost component | Value 2026 | Primary source |
|---|---|---|
| Industrial Electricity Prices for Commercial Customers (2026 Forecast) | ~16.0 cents/kWh | BDEW Electricity Price Analysis 10/2025 |
| Industrial Electricity Price 2025 (Actual) | 17.8 cents per kWh | BDEW 10/2025 / SMARD 02/2025 |
| LCOE for Rooftop PV (10–1,000 kWp) | 5.7–12.0 cents per kWh | Fraunhofer ISE July 2024 |
| Typical on-site purchase price for commercial use | 11–13 cents per kWh | Industry Benchmark / dena PPA Market Analysis 2024 |
| Minimum discount (16 − 13) / 16 | 19 % | own calculation |
| Maximum discount (16 − 11) / 16 | 31 % | own calculation |
| Stated range | 20–30% | conservatively estimated |
Important caveat: Starting January 1, 2026, the manufacturing and agricultural sectors will be subject to a permanently reduced electricity tax rate of €0.50/MWh (instead of €20.50/MWh)—an indirect subsidy for energy-intensive industries. This reduces the effective grid electricity baseline by up to 2.0 ct/kWh and may slightly diminish the percentage benefit for these companies. In absolute cents, the benefit remains high. Additional subsidy programs or government credit lines apply to the purchase route, not the contracting solution.
Calculation example: A typical medium-sized business with 500 kWp
Example company: 500 kWp rooftop system, 480,000 kWh annual generation, 300,000 kWh self-consumption, 180,000 kWh surplus feed-in. Compared to current grid electricity purchases, this results in annual savings in the mid-five-figure range; over 20 years, this amounts to approximately €435,000. The exact figures depend on the inflation rate, electricity price trends, and the actual proportion of self-consumption.
Detailed assumptions: specific annual yield of 960 kWh/kWp (southern Germany, unshaded flat roof orientation), self-consumption rate of 62.5% without storage, fixed purchase price of 12 ct/kWh with 1.0% annual indexation, projected grid electricity price path of 2.5% per annum Increase starting from 16 ct/kWh. Surplus electricity is sold directly by Logic Energy—these revenues do not go to you as a customer. The project is self-financing through the difference between the PPA price and the grid electricity price; no additional subsidies are required, and no additional costs are incurred.
| Key figure | Value Year 1 | Total: 20 years |
|---|---|---|
| Electricity consumed for own use under PPAs | 300,000 kWh | 6.0 million kWh |
| Electricity costs under the PPA (12 cents/kWh, indexed) | 36.000 € | ~ 793.000 € |
| Hypothetical grid electricity costs (16 cents/kWh, 2.5% per year) | 48.000 € | ~ 1.228.000 € |
| Savings compared to purchasing from the grid | ~ 12.000 € | ~ 435.000 € |
| CO₂ emissions avoided (380 g/kWh) | 114 t | 2.280 t |
| impact on the balance sheet | No capitalization, no depreciation expense; the asset belongs to Logic Energy | |
| Impact on liquidity | €0 CAPEX, €0 OPEX, only variable electricity costs | |
Based on this conservative estimate, the 20-year benefit amounts to approximately €435,000 —without taking into account CBAM compliance, ESG reporting benefits, or incentive programs. In scenarios involving steeper increases in grid electricity prices or higher self-consumption rates, total savings of up to €900,000 are realistic.

On-Site PPA vs. Off-Site PPA — Which Option Is Right for You?
An on-site PPA utilizes the rooftop space directly at your company’s location; the electricity flows directly into your production facilities and partially bypasses transmission fees. An off-site PPA sources electricity from a remote solar park via the public distribution grid and is subject to grid fees, surcharges, and balancing group management. For companies that own their own property, the local option is almost always the more economical choice—which is why Logic Energy focuses on this form of electricity supply.
Power purchase agreements come in several forms, which vary depending on the location of generation, the delivery route, and the type of contract. An overview of the most important power purchase agreements:
| Criterion | On-Site PPA | Off-site PPA (physical) | Synthetic PPA | Merchant PPA |
|---|---|---|---|---|
| Location of the facility | Your property | Off-site solar farm | Any, financial contract only | Grid-connected system |
| Electricity supply chain | Immediately after the junction | Public distribution network | No physical current | Spot market-linked |
| Grid fees | Exempt for personal use | The traps are full | Not relevant | The traps are full |
| Purchase price in 2026 | 11–13 cents per kWh | €29–41/MWh + grid costs | Contract for Difference | Spot price ± margin |
| Minimum size | from ~100 kWp / 150,000 kWh | usually 2 MWp or more | usually 5 MWp or more | usually 1 MWp or more |
| Target audience | Small and medium-sized businesses, farmers | Corporations | Corporate PPA with Treasury | Producers without buyers |
| Focus on Logic Energy | Core offering | upon request | not in the portfolio | not in the portfolio |
The off-site base prices are taken from Enervis’s Solar Pay-as-Produced Tracker (as of January 2026) and represent electricity costs only—grid fees, surcharges, and balancing group costs are added on top. The on-site price, in cents per kilowatt-hour, is directly comparable to your current electricity rates, whereas the off-site base price must always be converted.
A corporate PPA is not a technical term, but rather describes the structure of the contractual relationship: a large corporation as the buyer that specifically purchases green electricity—often for ESG or CBAM reasons. For Logic Energy’s SME customers, the on-site option is the simpler and more cost-effective choice, offering the greatest benefits during day-to-day operations.
Who should consider taking out this policy? Industries & Minimum Size Requirements
Ideal for annual consumption of approximately 150,000 kWh and 800 m² of usable rooftop space (approximately 100 kWp of installed capacity). Particularly suitable for: production facilities, logistics centers, cold storage facilities, agricultural buildings, and data centers. Tenants with long remaining lease terms also benefit, as do cost-conscious companies and customers without their own O&M expertise. Logic Energy deliberately focuses on the SME segment between 100 and 1,000 kWp—the gap between residential properties and large-scale industry.
Small and medium-sized commercial and manufacturing businesses—including metalworking, chemicals, food production, and plastics processing—benefit the most because production takes place during the day and self-consumption rates of 60–80% are realistic. Agriculture and agricultural logistics, with machinery sheds, barns, and cold storage facilities, often have large, south-facing areas and consumption tied to the time of day (milking equipment, cooling, ventilation); starting in 2026, the electricity tax benefit will also come into effect. Industries with shift operations regularly achieve self-consumption rates exceeding 85% thanks to base load. Logistics and retail—often tenants of large warehouse spaces—frequently have structurally weak building envelopes, for which Logic Energy’s roof bridging system offers a solution at minimal additional cost.
Special Situation for Tenants: If your company leases the property, the model can be set up in collaboration with the owner—the owner benefits from the property’s increased value, and the tenant benefits from affordable electricity. Many tenant-owner arrangements operate as a classic three-way partnership, in which Logic Energy handles the operational implementation and both parties enjoy clear benefits.
| Parameters | Lower limit | Ideal |
|---|---|---|
| Annual electricity consumption | starting at ~150,000 kWh | 300,000–2,000,000 kWh |
| Usable rooftop area | starting at ~800 m² | 2,000–10,000 sq m |
| System capacity | from ~100 kWp | 300–1,000 kWp |
| Contract Term for the Building | at least 20 years or ownership | Ownership |
| Remaining load-bearing capacity of the roof structure | > 15 kg/m² or a bridging system | > 25 kg/m² |
Smaller projects (starting at around 50 kWp) are possible, but they are more costly and require a differently structured contract. An alternative to traditional financing through equity or bank loans is installing your own PV system for your business.
Technology: Even on industrial roofs with poor structural integrity
Many industrial roofs (trapezoidal sheet metal, sandwich panels, lightweight construction) are considered “unsuitable for PV” because their load-bearing capacity is less than 15 kg/m²—the standard value for mounted solar systems. Logic Energy uses its own bridging system that transfers the loads to load-bearing purlins and supports instead of the roof surface itself. This makes it possible to install systems on roof areas that standard operators reject—a significant advantage for many existing buildings and industrial photovoltaic systems.
The principle involves an elevated substructure that hovers above the actual roof assembly and transfers its load directly to the primary structure. This also creates a rear-ventilated air gap that lowers the module temperature and typically increases the specific yield by 2–4%. At the same time, the module surface protects the underlying roof membrane from UV radiation and weathering—another advantage: the remaining service life is generally extended significantly.
Before construction begins, a certified structural engineer assesses the structural capacity and custom-designs the substructure. For existing buildings with incomplete documentation, Logic Energy, as the project operator, conducts structural analyses based on core samples. The costs for structural engineering and the substructure are included in the final price and are not billed separately—a transparent pricing model with no hidden fees.
Yield structure: 20 years, three distinct maturity options
The power purchase agreements have a term of 20 years from the date of commissioning. The contract specifies a fixed purchase price per kWh with moderate indexation, the use of the land via an easement recorded in the land registry, the transfer to new owners upon sale of the property, and the three termination options. No automatic renewal, no obligation to renegotiate at your company’s expense—maximum legal certainty for both parties.
The three options at the end of the term are set in advance: purchase at residual value (typically 10–15% of the original acquisition cost), free dismantling by Logic Energy—including professional disposal and recycling—or renewal at prevailing market terms and prices, which are significantly lower after 20 years because the system has already been depreciated. These three options provide your company with complete peace of mind in all decision-making.
Real Estate Sales: The easement is automatically transferred to the new owner as part of the contract. This is not a risk, but often a selling point: the buyer secures a fixed, low electricity rate for the remainder of the term. Some clients actively market the existing contract as a selling point during the sales process—the predictability it offers over 20 years is a genuine asset.
Surplus electricity: If the system generates more electricity than your business consumes (on weekends, holidays, or during the low-demand summer months), Logic Energy feeds the surplus into the public grid and sells it directly. These revenues remain with the system operator—they are part of the cost structure that makes the low purchase price possible in the first place. Our analysis of the direct marketing of PV electricity explains the background to these market mechanisms.
Risks and what you should know beforehand
The main risks lie with the plant operator: revenue risk, electricity market price risk, and maintenance costs. Your company needs to consider three aspects: the 20-year commitment to land use, the regulatory framework (in particular the Solar Peak Act and the Renewable Energy Act), and the financial worst-case scenario in the event of falling electricity prices. The solution deliberately distributes the risks asymmetrically in your favor.
| Risk | Who wears it? | How can it be reduced? |
|---|---|---|
| Loss of revenue (weather, technical issues) | Logic Energy | Pay-as-you-go, insurance, 24/7 monitoring |
| Maintenance, repairs, inverter replacement | Logic Energy | Full service included, no additional charges |
| Price risk in the spot market (surplus) | Logic Energy | Direct marketing with a risk premium factored in |
| Regulatory risk (amendments to the Renewable Energy Act) | Both parties | Contractual hardship clauses |
| Solar Peak Act: Negative Prices | Logic Energy | Structurally factored into the purchase price |
| Commitment to 20 years of land use | Your company | Easement; Transfer upon Sale |
| Falling grid electricity price below the purchase price | Your company | Index formula with a cap; has not occurred historically |
| Insolvency of the plant operator | Your company | Easement remains in effect; easement is transferable |
| Business Closure / Relocation | Your company | Contract Transfer Through the Sale of Real Estate |
| green: low risk · yellow: mitigated residual risk · red: high risk | ||
The Solar Peak Act deserves a separate section: As of February 25, 2025, the feed-in tariff will no longer apply during periods of negative prices, and the direct marketing requirement will apply to systems as small as 25 kWp (instead of 100 kWp). For full feed-in providers, this is a deterioration—for our type of power purchase agreements with high self-consumption, however, it is structurally neutral to positive, because the self-consumption share is independent of the market price. Details in the context of the 2026 EEG feed-in tariff.
Pay-as-produced vs. Pay-as-nominated: Logic Energy uses a pay-as-produced standard contract—you pay only for the electricity that is actually generated and delivered. Shortfalls in supply due to weather or technical failures do not affect your company, but rather the producer. Pay-as-nominated (fixed supply volume guaranteed) is available upon request, but incurs a risk premium—an option for companies with particularly planning-intensive energy needs.
PPA vs. Buying, Financing, and Renting — A Four-Way Comparison
A PPA means zero upfront investment, predictable costs of 11–13 ct/kWh, 20 years of price certainty, and no impact on the balance sheet. Purchasing the system (using equity or a KfW loan) results in electricity generation costs of 5.7–12.0 ct/kWh, but ties up investment capital and requires O&M responsibility. Leasing a system is rare and usually more expensive. Rule of thumb: Preserve liquidity → choose the contracting route. Capital available and want to maximize returns → purchase.
| Criterion | PPA / Contracting | Purchase funded by equity | Purchase with KfW-270 | Equipment rental |
|---|---|---|---|---|
| Investment needs | 0 € | ~€700–1,500/kWp | typically 10–20% equity | 0 € |
| Property Investment | Logic Energy (20 years) | Buyer | Buyer | Landlord |
| Wholesale prices | 11–13 cents per kWh (fixed rate) | 5.7–12.0 ct/kWh LCOE | LCOE + Interest | often 13–16 cents per kWh |
| Balance sheet effect | Off-balance | Capitalization, depreciation over 20 years | Capitalization + Loan | Off-balance possible |
| Tax levers | no | Depreciation and Amortization | Depreciation and Amortization | Rent is tax-deductible |
| O&M costs | Logic Energy | The buyer themselves | The buyer themselves | Landlord |
| Risk transfer | All providers | Buyer | Buyer | some landlords |
| Flexibility at the end of the term | 3 contractual options | full (ownership) | in full after repayment | Returns |
Rule of thumb: If you have more than €500,000 in available equity, possess O&M expertise, and are aiming for maximum cash flow, you should buy. If you want to preserve liquidity for your core business, need balance sheet discipline, or are interested in a full-service solution, choose the contracting option—a key component of the energy transition for small and medium-sized businesses. For details on the rationale for purchasing, see “Your Own PV System for Your Business”; for specific return-on-investment calculations when purchasing, see the Photovoltaic Industry Guide. Those who wish to actively invest in photovoltaics (as a capital investment, not as a consumer) will find the right solution in the Logic Energy Investor Model —which represents the economic opposite.
The contracting model isn't suitable if your building will need to be renovated in less than 15 years and you don't want to coordinate that through a contract, if you sell the property in the near future and the buyer refuses to accept the easement, or if your annual consumption is less than 80,000 kWh—in those cases, smaller self-purchase solutions are more cost-effective.
The German PPA Market in 2025/2026: Figures and Insights
With 48 signed contracts and 2.04 GW in 2024, Germany is the European leader in power purchase agreements (Pexapark). Prices for solar energy fell by around 20% in 2025 and stabilized in 2026 at €29–41/MWh on an off-site basis (Enervis). Hybrid agreements (PV + storage) are growing rapidly; the CBAM requirement starting in 2026 is increasing demand for green energy. The SME commercial rooftop market remains underserved—here, Logic Energy is positioning itself as a specialized company for commercial rooftop spaces.
By the end of 2025, installed solar capacity in Germany stood at around 120 GW (BDEW/UBA). The share of renewable energy in gross electricity consumption reached 55.1% (UBA) to 55.8% (BDEW/ZSW)—marking the first time that renewables accounted for the majority. At the same time, prices for businesses—projected at ~16 ct/kWh in 2026—remain roughly three to four times higher than the generation costs from their own solar installations. The structural gap that makes such investment solutions economically viable is secured well into the 2030s—the energy transition provides the framework here, demand is real, and political support reinforces the trend.
The gap in the SME sector. Corporate contracts focus on conglomerates and large-scale industry with capacities of 5 MWp or more. The B2C market targets single-family homes up to 30 kWp. In between—in the 100–1,000 kWp rooftop segment—there are only a handful of specialized providers for new installations in Germany. This is precisely where Logic Energy focuses: owner-managed, SME-focused, with proprietary bridging technology and a direct line to management. Current trends—falling module prices, rising CO₂ prices, and mandatory smart meters starting in 2026—further support this positioning.
Solar power without equity is not a financial gimmick, but an established form of commercial energy supply and a concrete business product for the energy transition in the SME sector—a proven energy solution for commercial rooftops. Those who sign a contract today secure 20 years of price stability in an environment where Germany now leads Europe in solar deals and where regulatory developments (Solar Peak Act, CBAM 2026) structurally favor the contracting principle. For companies with an annual consumption of 150,000 kWh or more and usable rooftop space, the path is clear: roof inspection, feasibility analysis, decision—without tying up liquidity and without impacting the balance sheet. The alternative—purchasing your own system—remains economically attractive for customers with available equity and in-house O&M expertise; our comparison with the purchase model guides you through the decision-making process.
Why Logic Energy and mediplan Helm e.K.?
A PPA binds you to a contractual partner for 20 years. The liability structure of the other party is therefore a key factor in building trust—and this is where Logic Energy stands out from the competition in the PPA market. The contractual partner is mediplan Helm e.K., a registered merchant with unlimited personal liability of the owner pursuant to Sections 1, 17, and 19 of the German Commercial Code (HGB). This means that the owner is liable with his or her entire personal assets for the fulfillment of the contract over the full term. In the case of limited liability companies (GmbH), liability is limited to the share capital.

FAQ
-
Zero euros in equity, zero euros in CAPEX, zero euros in OPEX—Logic Energy covers all investment costs. Your company pays only for monthly consumption at a fixed price—typically 11–13 cents/kWh, which is 20–30% below grid prices. No hidden fees, no maintenance charges, no insurance premiums. All-inclusive—these are the key benefits for your company.
-
Cost-effective for annual consumption of approximately 150,000 kWh and 800 m² of usable rooftop space (approximately 100 kWp system capacity). Smaller projects are technically feasible but will be less efficient. We’ll determine the exact parameters for your location in a free initial assessment within 48 hours—a risk-free project assessment.
-
The contract is automatically transferred to the new owner via an easement. Many buyers view the fixed, low electricity rate as a selling point—you’re essentially selling a locked-in energy price along with the property. No risk, no hurdles in the transaction, and no right of termination by third parties.
-
Logic Energy uses its own bridging system that distributes the module load across load-bearing purlins and supports rather than the surface itself. This makes it possible to use trapezoidal sheet metal, sandwich panel, and lightweight structures with low load-bearing capacity—an option that standard providers usually rule out. Structural analysis and the substructure are included in the price; the analysis is performed on-site by a licensed structural engineer.
-
No problem. Your company will continue to purchase any remaining electricity needs (at night, in winter, or during peak demand periods) from your current provider as usual—in parallel with the supply from the on-site system. The higher your self-consumption rate, the greater your overall savings. With optional battery storage, the self-consumption rate typically rises to 70–90%, and your energy independence increases significantly.
-
Logic Energy is the sole plant operator. As the owner, we cover all ongoing operational costs: maintenance, cleaning, monitoring, insurance, repairs, and inverter replacement. Your company incurs zero expenses and assumes zero liability—the technology does not appear on your balance sheet, and we handle all aspects of the project as your long-term partner.
-
The initial term is 20 years. After that, there are three options: purchase at residual value, free dismantling by Logic Energy, or extension of operations under significantly more favorable terms prevailing in the market at that time. All three options are contractually specified in advance—there is no automatic renewal.
-
Contracting option: €0 investment, 11–13 ct/kWh, 20-year planning horizon, no impact on the balance sheet. Purchase: ~€700–1,500/kWp CAPEX, LCOE 5.7–12.0 ct/kWh, but capital tied up, depreciation benefits, and ownership. Electricity consumers who want to remain liquid should choose the contracting option.

No. The calculation works because the production costs for rooftop solar systems range from 5.7 to 12.0 ct/kWh (Fraunhofer ISE 07/2024), while grid prices range from 16 to 18 ct/kWh (BDEW 10/2025). We share the margin between these two figures with you: You receive a 20–30% discount, and Logic Energy receives the remaining margin over 20 years.
