ProVision Solar has completed the installation of a 105-kilowatt solar electricity generating system on the roof of Molokai General Hospital, the largest such system on the island.

The system’s 315 photovoltaic panels will produce about 25 percent of the hospital’s power needs, or an estimated 170,000 kilowatt hours of electricity in its first year of operation, according to Hilo-based ProVision Solar.

Molokai General Hospital officials signed a power purchase agreement with California-based Solar Power Partners, which will operate the PV system and sell power back to the hospital at a fixed rate over the life of the contract.
The price tag for the project and terms of the power purchase agreement were not disclosed. However, under most power purchase agreements the customer buys the electricity from the system operator at rate less than what the customer would pay to its local utility.
