Typical Residential Installation

Many prospects ask us "What will a typical system cost?" In reality, there is no one typical system, since the size of system needed depends on the amount of electricity consumed, and everyone's lifestyle and home are different. However, most Northern California homes will need about 3 - 4 kW of DC generating power to produce enough kWh to cover their annual electricity consumption. Use the scale below to determine what you should budget for a solar electric system to cover the expensive "above baseline" portion of your electricity needs (note that these numbers assume optimal conditions, which our free site evaluation and financial analysis will check):

Monthly kWh usage	Size of DC system needed	Approximate Cost (After Rebates/Tax Credits)
500	2.4 kw	$13,000
750	3.6 kw	$19,000
1000	4.7 kw	$23,000
1500	7.1 kw	$34,000
2000	9.4 kw	$45,000
2500	11.8 kw	$57,000

Our financial analysis can show you what your payback time will be if you decide to pay for this remaining cost all at once, or what your cost per kWh (compared to what PG&E charges you) will be if you finance this expense as part of a home equity loan or added to your existing first mortgage next time you refinance - you'll be pleasantly surprised at the financial results!
