How Many Solar Panels Do I Need?

Posted on: September 25, 2013

Considering solar in San Diego? If so, naturally you have a lot of questions about installing a system. Today we will address a common question: “How many solar panels do I need?”

We are asked this question often by prospective solar customers, and the answer changes every time.

The only right answer to this question is “it depends on your needs, your budget, and the amount of space you have available.”

If you strictly want to know how many solar panels you need to meet approximately 100 percent of your energy needs, the question becomes a little easier to answer. While there are a number of factors that can impact the production and efficiency of solar panels, a fairly straightforward way to estimate the number of solar panels you need is to determine your average electric demand. Once you have this number—measure in kilowatt hours—multiply that number by 0.25. This will give you an approximate number of solar panels required to completely offset your energy usage.

How to Accurately Determine How Many Solar Panels You Need

The only way to accurately determine exactly how many solar panels you need to meet your home’s energy demands is to have a solar professional out to your house to analyze your solar potential.

Solar production varies depending on the orientation and pitch of your roof, so two homes with identical energy usage could require different amounts of solar panels depending on whether their home’s roof has a North-South orientation or an East-West orientation. Roofs with southern exposure (or northern exposure in the Southern Hemisphere) will generate the most electricity and will require fewer solar panels to meet electrical demands.

Unlike many solar companies that will come out and suggest a system designed to meet the demands of your current energy usage, we do things a little bit differently. We will first help you determine where you can reduce your energy consumption. By making energy efficiency upgrades and reducing your energy consumption first, you will need a smaller—and less expensive—solar array to meet your energy needs!
