PV Calculator

high-precision estimates for your location!

Would you like to know how much output your solar electric system will generate? Our PV Calculator is based on real solar energy data from the last year. It gives you a reliable estimate how your system would have actually performed in 2007.

Price: The price for a PV Calculator report is $ 30 and can be paid online through the PayPal transaction system.

The PV Calculator gives very precise information in terms of location. It's precise up to the street block. This high resolution is the result of satellite imagery from the national weather satellite. Please enter your address in this GIS web site and transfer your geographic coordinates to the fields provided below. Locations in the US have a positive latitude and a negative longitude. You will get better accuracy when you enter longitude and latitude with three decimal places.
*Longitude *Latitude Please provide some basic description of your PV system. Most important are the kW peak size, the tilt angle and orientation of your system. The kW peak size specifies the rated output of your PV panels. The tilt angle is the roof inclination in degrees from the horizontal plane. The orientation angle specifies how your system is oriented: North = 0, East = 90, South = 180, West = 270 degrees.*kW peak system size *Tilt angle *Orientation *Email where you want to receive your PV Calculator report By clicking on the submit button you will be directed to a PayPal payment site.
