solar grid inverter producers are encouraged to sell them as they earn them

In many states, like my home of New Jersey, you can actually get paid for your efforts. While you cannot physically sell the power you make, you can receive rebates and savings through state programs. In NJ, this is done through SREC (Solar Renewable Energy Credits). These are given on a monthly basis based on the number of KW/h your solar panels generate. The credits are a trade able commodity, with market price subject to supply and demand. Utility companies are required to buy a certain number of these credits each year. The credits are expected to go down in value predictably as more people enter the market by generating their own solar. Therefore, solar grid inverter producers are encouraged to sell them as they earn them.

Another way to save/earn money from solar is to lease your affordable space to an entity that will use it to produce solar. Leasing your available space will provide monthly rent from an area of real estate that was presently unable to produce income. Large rooftops, especially distribution centers or office spaces, are prime candidates for this arrangement. Any company with a usable roof should consider setting up some form of hybrid solar inverter generation. What else are you going to put on the roof that will earn you money?
