Measuring Space for Your New Solar Panels

You may be surprised to learn how viable solar panels have become in our neck of the woods. Recent advances make it possible to generate copious amounts of solar energy no matter how cloudy the day itself is. In towns like Auburn, WA solar energy has exploded in the last few years, and homeowners have eagerly embraced the technology as a means of producing clean, efficient energy for a very low cost. Besides the initial cost of investment and solar panel installation, all you need is sufficient space on your property to hold the panels. In some cases, this means setting it up in your yard, but most people want the panels on their roof, where they can get the most sunlight exposure as well as staying out of the way. Here’s a few tips for measuring space for your new solar panels.

First you need to determine how large the panels need to be in order to power your home. A trained professional can provide precise calculations, but generally speaking, you need to:

  • Determine the average kilowatt hours you use every year. (You can check your electric bills over the course of a year to get an exact figure.)
  • Determine the number of hours your home gets sunlight exposure. Cloud cover rarely matters, but you do need to know how many hours the sun is in the sky each day, and factor in the changes in season as well. (You’ll probably see a lot more sunshine each day in June that you will in January.)
  • Divide the kilowatt hours you receive each year by 365 (the number of days in a year). Then divide that number by the average number of hours your home receives sunlight, and divide that number by .75 (to include an efficiency constant, and ensure that the system doesn’t get overloaded).

The result is the number of kilowatts your array will need. As a general rule, you’ll need about 80 square feet for every kilowatt required by your system. From there, you can measure the amount of space required in your roof or yard. The experts at Sound Heating can help you with measuring space for your new solar panels.
