PV Yield per kWp in 2026: How Many kWh Are Realistic?
In 2026, a solar power system in Germany will generate an average of approximately 1,000 kWh per kWp per year; for south-facing systems, this figure ranges from about 970 to 1,130 kWh, depending on the region—the key metric for comparing systems of different sizes and locations. How this value is derived from irradiance, performance ratio, and degradation.
Investing in Renewable Energy in 2026: How Photovoltaics Stack Up Against Wind, Hydro, and Bioenergy
Anyone looking to invest in renewable energy in 2026 has four options: solar power, wind power, hydropower, and bioenergy. An honest comparison of returns, tax benefits, risk, and liquidity—with clear recommendations for investors with at least €100,000.
Agri-PV as an Investment in 2026: Why Investors with €100,000 Should Take Advantage of the Funding Window Now
The EU state aid approval for the EEG 2023 expires on December 31, 2026; the CfD requirement for systems of 100 kW or more is expected to take effect on July 17, 2027. What this timeframe means for agri-PV investments requiring at least €100,000 in equity—lease factors, Building Code (BauGB) exemptions, and return-on-investment ranges.
Will solar power still be worth it in 2026—despite the CfD requirement, the phase-out of the EEG, and the debate over module prices?
Two risks are causing uncertainty in the PV market in 2026: the mandatory CfD requirement effective July 17, 2027, and the phase-out of EEG subsidies on December 31, 2026. The rise in module prices seen in the first half of the year has leveled off since July. Photovoltaics remain attractive for investors and businesses—offering a 6–10% annual return, with tax benefits potentially increasing the yield to 12%.
Battery Storage Investment in 2026: Revolution or Risk? Opportunities, Models, and Policy Leverage
Is investing in battery storage worth it in 2026—and how? Models, revenues, returns, and the tax incentives under Section 7g of the German Income Tax Act (EStG) and declining-balance depreciation in an honest analysis of opportunities and risks for commercial investors.
Photovoltaics in Portfolio Planning: How Does a Financial Advisor Classify PV Systems?
Money market accounts yield almost nothing in real terms—is a solar power system worth including as a tangible asset in your portfolio? A financial advisor explains asset allocation, after-tax returns, and the four risks that no salesperson will mention on their own.
Section 14a of the Energy Industry Act (EnWG) and Battery Storage: What Do Investors Need to Know in 2026?
As of January 1, 2024, new battery storage systems with a capacity exceeding 4.2 kW fall under Section 14a of the Energy Industry Act (EnWG)—with reduced grid fees and guaranteed grid connection in return. What investors need to know in 2026.
Grid Fees in 2026: What Does the AgNes Reform Mean for PV Investors?
On August 6, 2026, the Federal Network Agency published the complete draft of the AgNes regulations. It ties the grid fee exemption for storage systems to a final investment decision made before January 1, 2027—which must be documented by March 31, 2027. The consultation period runs through September 18, 2026.
Photovoltaic Expansion in 2026: What the Numbers Mean for Investors and Businesses
Net PV capacity additions in the first half of 2026 totaled 7,931.1 MW—roughly on par with the previous year. However, the mix has shifted: For the first time, ground-mounted systems accounted for more capacity than all rooftop systems combined, while the number of new installations plummeted by 18 percent.
Italy's solar market is shrinking in 2025: Why are small-scale systems losing ground while utility-scale systems are growing?
With 6.4 GW of newly connected PV capacity, Italy’s expansion in 2025 was five percent below the previous year’s level and 660 MW below the PNIEC target (Italia Solare, Feb. 7, 2026). Why this decline means a different market for German direct investors than in 2022—data, strategy, and 2026 forecast.
Negative Electricity Prices in 2026: How Often They Occur and What They Cost PV Investors
In 2025, the exchange price was below zero for 573 hours. How often do negative electricity prices occur, when exactly—and why it is not the exchange figure that counts for revenue calculations, but rather the figures reported by the transmission system operators.

Co-location combines a PV system and battery storage behind a single grid connection—resulting in a project IRR increase of approximately 29% due to shared infrastructure. An overview of technology, tax, and incentives for 2026.
Solar Power for Freelancers in 2026: Take Advantage of Tax Incentives, Avoid the Business Tax Trap
Photovoltaics offer freelancers a 6–10% return plus IAB and special depreciation benefits—but in a group practice, there is a risk of being classified as a commercial enterprise. This article analyzes the scenario and shows how spinning off the business avoids the trade tax trap.
PV Investment Italy 2026: Market Analysis, FER-X & Strategies
Italy’s subsidy framework has been back in place since August 2026: The FER-X Decree allocates 37.15 GW, and the strike price for photovoltaic power in the auctions is 80 euros per MWh.
