How does solar pencil out? Efficiency of solar equipment has risen sharply and prices have dropped. At the same time, local electricity rates are expected to rise at a rate of 2.2%/year. This takes much of the risk out of solar conversion and creates a high-tech win-win:

Scenario for a 5 kw system at $4.70 per watt:

Net outflows Net inflows
Gross cost: equipment, supplies, permits, labor $23,500
Washington State sales tax .00
One time Federal tax credit of 30% $7,050
Net cost of installation* =$16,450
Est. annual energy production payment from utility co. until 2022 $2,800
Avoided energy costs $500
Total annual positives =$3,300

*(resulting in a net cost of $3.29/watt)

Thus your system will have paid for itself within 6 years. After that, it is all profit!
