Run Down of the Costs and Earnings of Solar Electricity (Photovoltaic Panels)

The two tables below come from Energy Trust of Oregon. They outline what the costs and earnings would be for a typical solar electricity system (photovoltaic system) in Lake County, Oregon for Pacific Power customers. As Pacific Power is a public utility it is mandated to provide financial assistance for the renewable energy purchases of its customers.

The assumptions used to form the tables below are: the household is a Pacific Power customer, the home is located in Lakeview, Oregon, the solar system size is 3,000 Watt-dc, and the costs per Watt is $4.50.

As the tables show, the total costs of a photovoltaic system could be as low as $1,875 and it could earn $410 a year, that’s a 21% annual return on investment. Considering, the stock market rarely achieves a 10% annual return on investment, photovoltaic panels could make a lot of sense for both your home and your bank acount.
