Keep your solar panels in top shape! Yes, like any equipment, they need a little love from time to time. If you want to maximize their efficiency (and your energy savings), it is crucial to know how to properly maintain them. Here is a complete guide to give you all the tips you need, whether you are in the city or in the countryside.
Why maintain your solar panels?
You might think that your panels are self-cleaning thanks to the rain. Well, that’s partially true! But dust, pollen, and other delights like bird droppings can accumulate and affect their performance. By regularly cleaning them, you extend their lifespan and optimize their electricity production.
How to clean your solar panels yourself?
Are you ready to get your hands dirty? Great, but do it safely. Here’s what you’ll need:
- A garden hose with adjustable nozzle.
- A soft bristle brush or non-abrasive sponge.
- Distilled water (or alternatively, warm and non-calcified water).
- Protective gloves and, if necessary, a harness.
The steps to follow:
- Turn off the solar system and disconnect it from the power supply. Safety first!
- Rinse the panels to remove surface dirt. Avoid high-pressure cleaners that can damage the surface.
- Clean the panels with a soft sponge and distilled water. Gently scrub, like you’re cleaning your vintage car.
- Rinse thoroughly and let dry naturally.
Tip: Clean the panels early in the morning or on cloudy days to avoid thermal shocks (cold water on hot panels is not a good idea!).
Recommended cleaning frequency
The cleaning frequency varies depending on where you are. Here is a summary table:
Environment | Recommended frequency |
---|---|
Urban area | 1 to 2 times a year |
Rural area | 2 times a year |
Near trees | 3 times a year |
Desert area | 3 to 4 times a year |
Maintenance of other installation components
The panels are not the only ones that need attention. The inverter, for example, plays a key role in converting the produced direct current into alternating current. To keep it operational, here’s what you need to do:
- Dust off the inverter once a year and check the connections.
- Visually inspect the panels every six months to identify cracks or anomalies.
- If you notice a significant drop in production, do not hesitate to consult a professional.
When to call a professional?
Cleaning it yourself is good, but sometimes you need to know when to delegate. If you have a difficult to access roof or if repairs are necessary, a specialist will be able to intervene safely. A professional will also check the overall condition of your installation and may detect problems that you may not have noticed.
Frequently asked questions about solar panel maintenance (FAQ)
- Should panels be cleaned after each storm? No, unless there is an accumulation of debris or snow. In these cases, use a soft-bristled broom to clear the panels.
- Can hail damage the panels? Most modern models are designed to withstand hail, but in the case of severe storms, it is advisable to protect them to prevent damage.
