PV Gap

Robert Said:

DIY home solar panels?

We Answered:

Not worth it unless you can get a fat subsidy. But Congress is working on a bill to provide a significant subsidy, and Oregon may have one as well. A solar plant costs about $10 per watt of installed capacity, and can produce a maximum of two kWh per watt per year -- which is worth about two bits. Without a subsidy, you are better off leaving your money in a savings account.
