Solar panels can reduce your utility bills and minimize your impact on the environment, and they’re most effective in areas that enjoy year-round sunshine. While modern panels are extremely efficient, there are a few steps homeowners can take to keep them working optimally. If you plan to switch to solar, here’s how to get the best results from the system.

3 Ways to Increase the Efficiency of Your Solar Panels

1. Make Sure the Solar Water Heater Is the Right Size

The size of your solar water heating system should depend on the number of people in your household. Two family members require around 20 square feet of solar collector area. In sunny states like Hawaii, you need 8 square feet extra for each additional person you live with.

For the water tank, you'll need around 1.5 gallons of storage for each square foot of collector. In sunny climates, some specialists recommend putting in a tank that can hold 2 gallons for every 1 square foot of collector. Having more tank space will help prevent overheating when there’s a low demand for hot water. Homes that frequently use dishwashers or bathtubs may need an even larger tank.   

2. Choose a Sunny Location

Put the panels on a section of roof that receives ample direct sunlight throughout the day. Shadows cast by tall trees will cover the cells, making even the most advanced solar panels a bit less effective. Depending on how much sunlight the roof receives, you may need to trim back overhanging branches or install the panels on the ground.

3. Keep Them Clean

Anything that keeps sunlight from reaching the cells will decrease the system’s efficiency. Even if the panels are in direct sunlight all day, dirt and grime will eventually limit their solar intake and energy output. Have professional technicians clean the panels every year to keep them clean and efficient.
