Good News: Our roof is almost perfectly south facing, we can pay cash for a solar system, and we can use every bit of the projected $11,000 Federal Tax Credit. Bad News: IF we install solar we will only install it on the portion of our roof that isn't visible from the street. This restricts the number of solar panels to 19... which optimum system designs (6.6kW) have mandated more expensive 345W or 360W panels. This combined with our need to replace our completely stuffed 200A main service panel with at least a 225A "solar ready" MSP and challenging Spanish clay tile roof (needs to be "picture framed) yielded this quote from SunPower 2 years ago: 19 X 345W: $33,268 225A MSP: included Roof Work: 2,850 Total: $36,118 Pre-Tax cost per Watt: $5.51 After-Tax cost per Watt: $3.86 ... and recently this $29,690 quote from SolarMax for a 7.26kW system with 22 LG 330W panels (no MSP upgrade... and honestly i don't think they can install 22 panels where they think they can) Pre-Tax cost per Watt: $4.08 After-Tax cost per Watt: $2.86 The issue is our SCE TOU-D-B-SDP bill only runs $80 per month (summer) to $200 per month (winter) for 800 kWh to 1,200 kWh per month on our 3,300 sq. ft. 2-story single family home in Newport Coast CA: 120 to 140 kW @ 25¢ kWh On Peak (2 PM to 8 PM) 300 to 400 kW @ 15¢ kWh Off Peak (8 AM to 2PM + 8 PM to 10PM weekdays + 8AM to 10PM weekends) 500 to 800 kW @ 10¢ kWh Super Off Peak (95% Tesla charging 10PM to 8AM every day) I'd really like to add solar but the R.O.I. is way too long... past my expected life expectancy since I'm almost 65. 8-( Almost every solar company (including Tesla, SunRun, etc.) refuses quote because we have a Spanish clay tile roof (needs to be "picture framed). Am I missing something?
