What Is Sun Number Score On A House?

One common question on the minds of homeowners looking to install a solar panel system: What does sun number score mean? A rating created by the company Sun Number, this score tells you how suitable your home is for harnessing solar energy. The higher your score, the higher the output you can expect from installing a solar panel system. However, if your home has a low sun number score, this shouldn’t put you off solar energy altogether.

In this article, we share with you some factors that affect the sun number score of your house.

What Is a Good Score?

Generally, a score above 70 is a good sign that you should go ahead with solar panel installation. It’s exceedingly rare for any house to get a perfect score of 100. Do not be put off if you get a score below 60 – you can still benefit from getting a solar panel system installed, albeit with a lower output.

Factors Affecting Sun Number Score

Below are some of the factors that play a part in determining the sun number score of your home:

  • Regional Climate: How much sun does your area receive? In Southwest Florida, where the sun shines almost all year round, you can expect your score in this aspect to be high. However, if your property is in a shaded area, this can lower your score.
  • Building: The building score is decided by factors such as the slope of your roof, the direction your property is facing, and more. Generally speaking, south-facing roofs score much higher in this aspect, and the larger the available area you have to install solar panels, the better. You should aim for a building score no lower than 50, and above 60 is ideal.
  • Electricity: One of the reasons you may be looking to install solar panels is to save money in the long run. Hence, the higher the electricity rates are in your area, the higher your electricity score will be. If the rates are low, this means that you may not see much of a difference in energy bills.
  • Cost: How much does it cost to install a solar panel system in your area? A lower cost will translate to a higher score.
