Equipment and products that enable us to use renewable energy instead of fossil fuels and conventional electricity are highly beneficial. Examples include solar thermal systems, solar electric (photovoltaic) systems, and wind turbines. Other power generation equipment, such as fuel cells and some energy storage systems (like batteries) are included here because they help us accommodate varied energy sources so that we may eventually move beyond fossil-fuel dependence.
SolarDock is a nonpenetrating solar-module mounting system for flat-roof and ground-mount installations. The product is held in place with ballasts and weighs 4 to 6 lbs/ft2 to withstand wind speeds of up to 90 mph (for greater protection, more ballast can be used for winds up to 120 mph). The product can be easily moved for routine maintenance or roof replacement. Panels are usually supported at a 25-degree angle, though other angles are available. SolarDock is UL-certified and comes with a 25-year warranty. Made in the USA.
GreenSpec lists inverters that convert the direct-current (DC) power produced by renewable energy systems into alternating-current (AC) power needed for most conventional appliances, and for feeding site-generated electricity into the power grid.
GreenSpec also lists power-conditioning equipment, controllers, batteries, and mounting equipment, as well as tracking systems that follow the path of the sun to maximize the amount of light hitting photovoltaic collectors.
