Solar Calculation
1. Figure What You Spend Now
If you don't know off the top of your head, it's easy to find out what you spend on electricity. The easiest way is to call your electric utility and ask how much you spend in dollars, and how many "kilowatt-hours" you use per year.
Write these down: $____________ per year ______________kwh per year
2. Find Your Zone
Each Solar in a Box Unit produces about this many killowatt-hours of electricity on average:
Per Month Per Year
Zone
3
112 KWH 1,340 KWH
Zone
2
135 KWH 1,620 KWH
Zone
1
155 KWH 1,860 KWH
Things to consider:
- How much usable roof do you have? Each Solar in a Box unit 6'x9' or 54 square feet
- Should you try to eliminate your whole electric bill? Not necessarily. What's more important is selecting a Solar in a Box system size that fits your roof and your budget.
- If your utility charges you more the more electricity you use, you'll get the most savings from using solar to eliminate the more expensive kilowatt-hours on your bill.
- Even small systems make a difference toward increasing America's energy independence and protecting the environment.
