Maintenance and care of photovoltaic systems: How to keep your solar system efficient
Once you've decided to install a photovoltaic system on your home, you should also consider the maintenance and care of your system. Even though photovoltaic systems are considered very low-maintenance, there are a few aspects you should keep in mind to maximize the efficiency and lifespan of your system.
1. Regular inspection: Why is it important?
Photovoltaic systems are known for their ability to operate for years without major maintenance. However, it's still advisable to conduct regular inspections to ensure the system is always operating at peak performance. Dirt, dust, or leaves can accumulate on solar panels and impair energy production efficiency. An annual inspection can help identify and resolve potential problems early.
Some important points to pay attention to are:
- Condition of the modules (possible cracks, dirt)
- Functionality of the inverters
- Stability of the fastenings and cable connections
2. Cleaning solar modules: When and how?
Rain generally keeps solar modules clean. However, in areas with little rainfall or high levels of dust and pollen, manual cleaning may be necessary. Dirt buildup can reduce your system's performance by up to 20%. Gentle cleaning with water and a soft cloth is usually sufficient. Avoid aggressive cleaning agents and high-pressure cleaners, as these could damage the module surfaces.
3. Monitoring systems: Always keep an eye on your system
Modern photovoltaic systems often have integrated monitoring systems that allow you to monitor the system's performance in real time. These systems inform you about the energy generated, self-consumption, and any malfunctions. Monitoring allows you to react immediately if a problem occurs, thus minimizing downtime.
4. How long does a photovoltaic system last?
Most photovoltaic systems have a lifespan of approximately 25 to 30 years. However, as with any technical system, performance can decline over time. Many manufacturers offer warranties on modules of up to 20 years, with efficiency declining only slightly after this time. Inverters, which play a central role in the system, typically need to be replaced after about 10 to 15 years.
5. Insurance and guarantees: A must for protecting your investment
A photovoltaic system is a valuable investment that deserves appropriate protection. Many providers offer warranties for the modules, inverter, and installation. There are also special insurance policies for photovoltaic systems that protect against damage caused by severe weather, vandalism, or fire. It's advisable to review the various options and ensure your system is adequately covered.
