We just got all our bills for April and the results are fantastic - sorry for being a bit boastful but this is really cool:
Electricity savings 93% versus April last year - that corresponds to an $11.40 electric bill. The savings came as a combination of behavior change and our 2.8 KW solar array. Last year our KWH was 600. this year our KWH usage was 303kwh which means we cut our electric bill in half via changed behaviors. we also generated 263KWH of power form our array leaving 40kwh on our bill which cost $11.40. Our PV array was 13,364 dollars and we received 30% rebate from the federal government and 2.25/watt from the state, so we received roughly 9,800 dollars in rebates!
Heating also improved, partly due to warmer weather...and that might explain a small portion of the reduced electric since we have forced air system. we reduced our heating by over 50% using the pellet stove and careful use of the thermostat.
our dollar savings for 2010 versus last year so far are:
