Washinton, DC row house solar array proposal, and challenges.
I am considering a new solar array for our home. After getting a quote I feel less hopeful and discouraged again from initial considerations and thoughts. The sales person and company seem to have worked the math backwards factoring in the federal credits/SRECs and what they can charge rather than cost + profit. They also scoffed at the suggestion to itemize the bill, even parts and labor split out. I also suggested that the each panel installed was about $1700 and got told you can't think of it that way as another vendor made the same statement about kWh some time ago; just set a bad tone for the confersation without a good explanation of why. At $100/month avg. bill for the last 5 years they quoted us 7.56kW system with a net cost of $15,500. This would be 101% of our electric usage. They mentioned the many benefits of the SunPower x22 panels @ 360w/panel and their warranty which are tangible but maybe inflated. I want to get another quote but maybe I'm not asking the right questions or thinking about it incorrectly.
Quote is $37,300 system, $11,200 fed tax credit, $10,600 SREC upfront = $15,500 Net out of pocket cost. This didn't include the roughly $3500 heavy up charge. I estimated the payback period is about 15 years, which is nearly double the suggest period. I understand the payback isn't the only factor, getting the house on renewable energy is great for our environment offsetting 500,000 lbs of CO2. I was hoping for some guidance and advice as to what direction to go.
