People often ask, “Is solar reliable?” Solar energy systems are highly reliable and have low maintenance costs. Solar electric systems installed by well-qualified solar installers typically have reliability rates above 98%.
Solar offers a fixed-cost hedge against future energy cost increases. It makes your future energy costs more predictable, and lower. Solar energy systems have high up-front cost, but once installed, the fuel (the sun) is free forever. Due to the thirty-year system life and very low maintenance costs, once the system is purchased, the cost […]
Growing public awareness of climate change and energy sustainability issues means installing renewable energy systems can be a good public relations move, and can help improve corporate image in the public eye. So it is not unusual to see solar news coverage of a large installation in your area, whether at a university or on […]
The most common type are not. Crystalline solar panels are mainly silicon and aluminum. The chips are very similar ways to computer chips. They are sandwiched between glass sheets and surrounded by an aluminum frame. No toxic chemicals used. Some thin-film solar modules use toxic materials such as Cadmium and Telluride, and we don’t usually […]
Solar panels are manufactured using similar methods as the manufacture of computer chips and glass panels. How much greenhouse gas does solar panel manufacture emit? The answer depends on the type of solar panel, says Vasilis Fthenakis, head of the Photovoltaic Environmental Research Center at Brookhaven National Lab. Fthenakis and has conducted extensive research on […]
