National Solar is a world leader in the origination, design, construction, financing and operation of renewable energy systems for the utility energy marketplace.
Newly published data from the Federal Energy Regulatory Commission (FERC), reviewed by the SUN DAY Campaign, reveal that solar accounted for over 75% of US electrical generating capacity added in the first nine months of 2025.
NLR maintains a chart of the highest confirmed conversion efficiencies for research cells for a range of photovoltaic technologies, plotted from 1976 to the present.
Residents of Çanakyayla which is a Kurdish-majority village in Turkey's Bitlis Province, have successfully halted a solar energy project, citing ecological concerns and displacement risks, the Mezopotamya Agency reported on Monday.
Off-grid solar systems typically cost between $45,000-$65,000 for a complete home setup, significantly more than grid-tied systems that average $15,000-$20,000. Battery storage represents the largest expense in an off-grid system, often accounting for 30-40% of the total.
Below, you can find resources and information on the basics of solar radiation, photovoltaic and concentrating solar-thermal power technologies, electrical grid systems integration, and the non-hardware aspects (soft costs) of solar energy.
Solar electric motors represent a remarkable fusion of solar energy and electric motor technology. They convert sunlight into electrical energy, which is then used to power electric motors.
European energy giant Vattenfall has started construction on a new hybrid renewable energy project in southwest Germany that combines wind and solar power at a single site. The project, called Hommerdingen-Biesdorf, will pair four wind turbines with more than 12,000 solar panels.
This can vary depending on your north-south location, but it generally ranges from 30-45 degrees for homeowners in the continental United States. Factors such as roof pitch and time of year can affect the overall efficiency of your arrays.
