Your solar system has a 30+ year lifespan (The inverter may have to be replaced after 15 years.), and we believe in low maintenance, trouble free operation. Sanyo systems costs are approximately $9 per watt installed for grid tied systems, but we also install other solar panels at a lower cost. (This is only an estimate since some installations are more complex than others.)
Begining in 2009, solar electric systems receive a 30% federal tax credit from the cost of the system. The credit is deductable over two years.
System Payback
Graph shows payback for a premium 5 kW solar electric system, adjusted for inflation (3%), with electricity at a cost of 13 cents a kW-hr. The graph includes the 30% federal tax incentive after the first year. Keep in mind this payback does not reflect any future electricity rate increases, which would improve your systems payback.
