How to check a solar panel is working?

To get the most out of your roof, it's important to take advantage of its full potential for production. Only with Holaluz can you cut your electricity bill down to €0, or even earn money, because we install as many** solar panels** as your roof allows. That way you produce more, have more surplus energy to sell,self-consumption surplus, and, therefore, save more.

Having the right installation is just as important as having all its components running like clockwork. That's the only way to make the most of your roof and the inexhaustible source of clean energy that is the sun. Regular maintenance will guarantee you the savings you expect on your electricity bill. 

Here's how to tell if a solar panel is working properly. But keep in mind that this requires electrical knowledge. For your safety, we recommend that these kind of checks should be carried out by professionals who are able to work at heights.

1. With the use of a multimetre we can measure the current, voltage and resistance values of a solar panel. 
2. Once these values have been obtained, they should be checked against the manufacturer's technical specifications. 
3. If the values are not similar, it's very possible that the solar panel isn’t working properly.

At Holaluz, we offer a solar panel maintenance service so you don't have to worry about any incidents. We take care of everything! The maintenance service we offer includes an annual cleaning and revision of your installation. We also remotely monitor how they’re operating, and if we detect that production has dipped, we’ll resolve it in less than 3 working days if it’s urgent, or in 2 weeks if it’s not. 

You can request the annual review of your installation whenever you prefer, but if you forget, don't worry: we’ll proactively schedule a date.
