SunPower’s solar panels already produce up to 50 percent more power on a typical residential roof compared with conventional panels,? said Tom Werner, SunPower’s CEO. “Our new line of high-efficiency inverters further enhances the performance advantage of SunPower’s solar systems and allows us to offer our customers an unmatched 10-year standard product warranty on the entire system.”

Hydrogen production from renewable methane, such as biogas from municipal wastewater treatment plants and landfill gas is ideally suited to SHEC’s solar hydrogen production system. Their solar hydrogen generator produces hydrogen from methane and carbon dioxide feed gases in a reactor maintained at temperature by solar thermal energy (directed by mirrors). A demonstration unit indicates that solar hydrogen generation is feasible, and appears to be cost-competitive with traditional methods.
