Solar panel prices may have risen in the last year, but they’re still 60% cheaper than ten years ago.

These energy-saving innovations are still a substantial investment for most homeowners. So, if you’re fortunate enough to own a residential solar system, you must take the best care of it.

Get started by avoiding these solar system cleaning mistakes to make the most of your investment.

1. Assuming Rain Cleans Your Solar Panels

One of the best benefits of solar panels is that they require very little maintenance. That doesn’t mean you can leave them to gather dust and dirt indefinitely.

Debris can scratch your solar panels over time, reducing their efficiency. Once your solar panels build up a layer of grime, even heavy rain or hosing won’t clean them sufficiently.

2. Using the Wrong Solar System Cleaning Products

Household cleaner or soap can damage the layer of solar panel protection manufacturers apply to the panels, making them vulnerable to the elements.

You must use a cleaning solution approved for PV panels and apply it gently with a soft cloth.

Pressure washers are great for cleaning roof tiles but keep them far away from your solar panels. They can damage the connections and seals on your solar panels, resulting in leaks.

3. Cleaning Solar Panels in Direct Sunlight

Always clean your solar panels in the early morning or late evening. When you wash them during the hottest part of the day, the water evaporates faster, so it’s less effective.

You could also end up with undissolved chemical residues on your solar panels that can hamper their production.

Besides, solar panels are at peak production during this time, so you don’t want to mess with them.

4. Not Drying Your Solar Panels Thoroughly

Too much water also harms your solar panels. After washing your solar panels, you must wipe them with a soft cloth until they are bone dry.

Pools of water can damage the surface of your PV panels or leave unsightly spots that block the sun’s rays. Make sure you dry between the solar panels to avoid rust in these areas.

A squeegee also works well for drying solar panels.

5. Not Turning Off the Power

If you have a dual meter installed, you must disconnect all your appliances from the grid before you start cleaning your solar panels. It’s not enough to switch off your main power supply.

Solar panels generate a direct current which can shock you if you inadvertently touch them with a metal object.
