Alternative Energy Systems: Size and Cost

You need to decide how much of your energy you want supplied by your solar electric system. If you want to be entirely independent, you will have to buy a large solar PV array. The same goes if you want to provide the bulk of power to your home: a large solar panel array will be needed.

Step 1: Energy usage

Our handy solar calculator will help you determine your needs.

As you calculate, also consider the following factors:

  • Does your weekly energy usage change? Do you use more on weekends? In the case of a cabin or cottage, you may be able to store energy during the full week.
  • Does your seasonal energy usage change? Do you use more in summer or winter?
  • How much energy variation is there within a day? How about from one day to the next? Energy usage per appliance may vary widely.

Step 2: Solar energy availability

Determine the number of full sun hours in your area. This varies seasonally, of course, and you can find handy data for your area using a solar insulation map or chart.

Step 3:

Both of these figures will be rendered in watts or watt hours or kilowatt hours (kWh). Divide the figure from step 1 (the number of watt hours) by the figure in step 2 (the number of hours of available sunlight). This will tell you the amount of wattage needed.

Medium sized solar panels have a standard wattage of 50 watts. A large panel (about 10 feet2) will render about 190 watts.

Regardless of how independent you want to be, you should have a certif...
