The system, designed and installed by Vista Solar, will offset WestGate Church’s electricity bill by nearly 95 percent. Vista Solar secured a $0 down, 15-year power purchase agreement (PPA) which allowed WestGate to be cash-flow positive from the start and is expected to save the church nearly $16,000 annually.
As part of the PPA agreement, Vista Solar will monitor the system for 15 years to ensure it is performing at or above expectations. Since the system sits on two pitched rooftops at the church’s San Jose facility, Vista Solar is using state-of-the-art online monitoring software which enables detailed visibility of both arrays from one platform, and provides system performance alerts.
The solar energy components for this system include SunPower X-Series solar panels delivering efficiencies of 21.5 percent, SMA Tri-Power inverters, Deck monitoring software, and a ProSolar racking solution.
A Local Partner
With more than 2,500 congregation members at two South Bay area locations, the savings generated will help WestGate Church continue to run its annual “local compassion” programs and pursue its goal to give away 50 percent of the church’s budget.
