Welcome to LIPA’s Solar Power Verification Web Site
Beginning in January 2002, the Long Island Power Authority (LIPA) began to collect sunlight information and other weather data from two specialized weather stations located in Hempstead and Riverhead.
LIPA is offering financial incentives to its customers to install a technology called "Photovoltaics" (abbreviated as "PV") that converts sunlight directly to electricity. (More information is available at www.lipower.orgon LIPA’s rebate programs.) This website uses local weather data from the two stations. By knowing the sun’s position, the local weather, and a few things about the PV system, it is possible to estimate the amount of power that should be produced.
This website is designed to do two things. First, if you already have a PV system, it will allow you to verify that your system is performing well. Second, if you are interested in installing a PV system, it will allow you to estimate how much electricity will be produced. All you need to do is click on one of the buttons below to begin:
