INFINITE SOLAR INCORPORATE Power Purchase Agreement (PPA), allows energy users to save on capital costs for solar panels, inverters and permits. What is a SOLAR POWER PURCHASE AGREMENT (SOLAR PA)? The solar power purchase agreement (or PPA) is a financial off-balance-sheet arrangement that allows an energy consumer, also known as an offtaker, to allow a third party developer to build, maintain, and operate a PV system on its land at no cost. After a set period, the off-taker agrees to buy electricity from its owner. The rate the off-taker receives will be typically lower than that of the utility, but they also get a sustainable power source and are able to implement sustainability initiatives.

This calculator sizes a solar system from your electricity use. Your monthly bill, divided by the average Louisiana electricity price, gives your yearly use; Louisiana's sunshine (1,479 kWh per kW of panels a year) then gives the system size that covers it, adjusted for roof direction and shade. The installed price is that size multiplied by the price per watt homeowners in Louisiana pay installers. Payback compares that price with what the panels save at Louisiana power prices, assuming prices rise 3% a year.
An estimate, not a quote. Roof size and pitch, shading, equipment, permits and the installer all change the final price; installers confirm it after a site visit.
