I'm torn...
Invest in a home solar system now, or wait 1-2 years and see what new options might materialize.
Do you want to continue to pay the power company mafia?
In our town, they are a monopoly... We have solar and are very glad we only pay the minimum to use their infrastructure to pass our excess production to them. (we do not sell the wats but do a 1 for 1 swap)
Of course, because they are a monopoly, and the mafia, they charge 16c a kWh for power we use in excess of that we produce... and, we just have to suck it up... but, the moment alternative energy is released, we will add that to our solar, maybe we will not need as big a system as a result.
