alt Hacker NewsYou might want to check on that net metering. A lot of utilities are moving toward net metering for a specified time (10-12 years or whatever) then moving to net billing. So once you hit the time limit they buy it from you like you're a producer at .03/kwh or whatever their purchase/production cost is.
Well, we already installed the system, so it's too late to change :P
Our utility is still offering 1 for 1 net metering for new installs (accumulated credit expires at the end of March every year) and have not proposed a new rate schedule. They say that existing connected systems will be able to remain on the current schedule indefinitely. That's the best I can do for the future at this point.
If it does change for us in a negative way, I'll have to bite the bullet and buy an electric car and charge when the sun is up. :P Hopefully negative changes happen later rather than sooner.
