When it comes to energy-efficient home improvement projects guaranteed to yield significant returns in the future, you can't go wrong with solar panels. They're an excellent investment, and when properly installed, they're low-maintenance. In Hawaii, which sees plenty of rain, they're even easier to take care of since the water can wash away most dust and debris. However, some contaminants still accumulate on the surfaces, so here's what to know about caring for them.

How to Maintain Solar Panels

1. Inspect the Panels

Before cleaning, check for nests and leaves. These substances become fire hazards when they're near the devices, as they reduce airflow and lead to the accumulation of heat. Additionally, look for any broken parts that call for professional repairs.

Because the panels are located on top of your home, safety must always be prioritized. Don't try to get up on the roof if you've never done it before and don't have the correct equipment, such as safety gear and a secure ladder. 

2. Stay Away from Abrasive Cleaners

If you're using a harsh cleaning solution and scratchy pads, you can accidentally scuff up the surface. Scratches can hinder the panels' ability to fully absorb the sunlight, limiting how much energy the system can generate. Therefore, you should always use soft rags and cleaners designed for solar panels. Even soap can leave a residue that can act like a shaded film and interfere with sunlight absorption.

3. Avoid Power Washing and Hard Water

The pressure from power washers can damage your solar panels. It can affect the reflective coating on the equipment and break the glass. A basic garden hose will suffice, provided you're not using a jet option. Additionally, use distilled or deionized water, which will ensure no minerals such as calcium accumulate on the surface after you're done cleaning.
