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 maintain them properly. Here is a comprehensive 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 joys like bird droppings can accumulate and affect their performance. By cleaning them regularly, you extend their lifespan and optimize their electricity production.
How to clean your solar panels yourself?
Are you ready to get your hands dirty? Perfect, but do it safely. Here’s what you’ll need:
- A garden hose with an adjustable nozzle.
- A soft-bristled brush or a non-abrasive sponge.
- Deionized water (or alternatively, warm and non-calcium water).
- Protective gloves and, if necessary, a harness.
Steps to follow:
- Turn off the solar system and disconnect it from the power supply. Safety first!
- Rinse off the panels to remove surface dirt. Avoid high-pressure cleaners that may damage the surface.
- Clean the panels with a soft sponge and deionized water. Gently scrub, as if you were 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
Depending on where you are, the maintenance frequency varies. 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 needing 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 spot 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 great, but sometimes you need to delegate. If you have a hard-to-reach roof or if repairs are needed, a specialist can intervene safely. A professional will also check the overall condition of your installation and may detect issues you might not have noticed.
Frequently asked questions about solar panel maintenance (FAQ)
- Should panels be cleaned after each storm? No, unless there is a buildup of debris or snow. In these cases, use a soft-bristled broom to clear the panels.
- Can hail damage panels? Most modern models are designed to withstand hail, but in case of severe storms, it is advisable to protect them to prevent damage.
