Vista Solar has completed a 118 kW solar power system for DPR Construction, a San Francisco-based builder.
The system employs SunPower X21/345 solar panels on Silverback Solar racking. Vista Solar installed Solar Edge inverters with DC optimizers on each panel to produce as much power as possible on the constrained rooftop, even when other panels on the roof are shaded by the adjacent buildings.
The system is expected to generate at least 158 MWh of electricity per year, helping DPR meet 100% of the building's annual electricity needs.
‘While we regularly build much larger projects, the challenge of finding solutions for the site constraints and being able to take part in a net-zero retrofit, right in our backyard, made this an inspiring project to work on,’ says Sam Kim, Vista Solar sales engineer.
