If you’ve invested in solar for your home, congratulations: You are an active participant in helping Hawaii reach its goal of 100% clean energy by 2045!

So, now what? For many of these homeowners, their solar energy and photovoltaic systems are “out of sight, out of mind” — until they see a problem with their electric bill. If you’ve had your system for a while, you might notice a decrease in energy output over time, which could cause an increase in your electricity needs from the grid — and a higher electric bill, too. According to Brennan Leong, president at Kapili Solar Roofing, it’s important to keep an eye out for telltale signs that your panels need to be cleaned or repaired.

“Dirty solar panels can impact the amount of energy they produce,” says Leong. “When dirt, dust or other debris accumulates, it can block sunlight from reaching the solar cells, which reduces output.”

The solution? Leong suggests using a soft brush or cloth and a mild detergent or cleaning solution, and avoiding high-pressure water that could damage the panels. Keep in mind, however, that damage caused by improper cleaning could void your warranty; call a professional to do this for you, if time and finances permit.

Maintain for Energy Gain

Other causes of decreased output could be physical damage to your panels or problems with wiring and other components. If you notice these issues, it’s important to have your panels inspected.

“The cost of maintenance varies depending on the type of panel, the age of the system and the extent of the maintenance required,” says Leong. Regular inspections and getting support as soon as you identify a shift in energy output will go a long way in sustaining the efficiency of your solar panels, he explains.

The bottom line? Panel health is key to ensure that you enjoy the benefits of your home’s solar installation, including reduced energy bills. The professionals at Kapili Solar Roofing can provide personalized services to help you along the way.
