Estimating Annual Production Value Tools

Photovoltaic Panel Simulation (javascript)
This is from MIT. It shows you the # of sun-hours you would expect to see from your solar panels at varying angles.

PV Watts Calculator
Estimates your annual production based on the Kw size of your system. For example if you have 4 x 200w panels, enter the DC value of your sytem at 800w. It takes into account your angle and orientation.

It will print out energy values over the course of the year in savings. Be sure to enter 24 cents per kWh in CT, which is really how much we pay (Jan 2011).

Annual Irradiation
Pages of data from NREL, telling you how much power to expect, month by month, from an array.
