Utility-scale solar uses only 0.07% of U.S. prime farmland, says SEIA
Released ahead of the U.S. Senate’s consideration of the 2026 farm bill, data shows that land used for utility-scale solar does not exceed 0.5% of prime farmland in any state, and is dwarfed by land used for golf courses and suburban development.
New research highlights the value of solar and energy efficiency in the home buying process
Research on the effects of clean energy and energy efficiency upgrades in the home buying process reveals a premium for homes with solar panels and heat pumps, but a disconnect between what consumers say they want and information available in listings and from agents.

US laboratory finds persistent ultraviolet light-induced degradation in solar modules
While 19 manufacturers received recognition as high achievers in RETC’s 2026 testing sequences, problems with ultraviolet-induced degradation in solar modules persist, while failing “red flag” scores increased in tests for damp heat and thermal cycling.

The hidden underperformance crisis in solar portfolios
Solar technology has come a long way. Modules are more efficient, inverters are more capable, and system design has become increasingly refined. On paper, the industry is positioned to deliver highly predictable performance. But in the field the story is often different.
Tandem PV announces 30.4% efficient perovskite/silicon demonstration module
The 100 cm² mini-module, featuring the company’s proprietary 4-terminal perovskite glass layer atop a high-efficiency Maxeon IBC silicon solar cell, is now in third-party certification. Company CEO Scott Wharton says the breakthrough paves the way for full-size modules that hit 28% efficiency later this year, aimed at the utility-scale market.
