Frequently asked questions

published by the company
My roof is waterproof and can’t be drilled, can I install solar panels?

Yes, we have technical solutions for all sorts of roofs. Inclined roof with simple overlays, with sandwich overlay, flat waterproof roof…

Our industrial unit is rented, can we install solar panels?

Yes, although you will need the authorization of the owner to do so. You can try to reach an agreement with the owner to share the installation costs.

I am the owner of the industrial unit but I have it rented, who would get the benefit of the installation?

All options are possible, but we advise you to create your own energy in situ. We can do it in different ways: through a rise in the rent price or through a service agreement by which the owner sells the solar kWh to the tenant, at a private and agreed price.

The maintenance of the installation is complicated?

Not at all: its mission is to be up there for 25 years, so you do not have to worry. That’s why it is installed by professionals. You won’t need to do anything: the rain will clean away the dust piled up in the gaps. If it hails, do not worry, the glass is designed to stand and hold (a car window breaks easier than many solar panels).

Can I hire only one type of maintenance or only cleaning?

The required service can be contracted, whether it is cleaning, corrective, operational, or preventive maintenance, according to the needs of the system and the recommendations of professionals.

What is the price of annual maintenance?

The price of the service varies depending on the installation's peak power and the services contracted. Rates for households start from €180+VAT and for industries start from €360+VAT. This will ensure optimal system operation and avoid costly problems in the future.

Is preventive maintenance recommended? Is cleaning of the panels recommended?

Regarding preventive maintenance, it is recommended to ensure proper system operation and prolong the installation's life and avoid costly problems in the future. Preventive maintenance includes tasks such as checking the solar panels (using a thermal camera if necessary), DC and AC wiring, connections, and the electrical system, as well as panel cleaning. In general, it is recommended to hire an annual maintenance service to ensure optimal system operation. Regular cleaning of solar panels is also recommended to ensure optimal system operation and prolong panel life, thus avoiding potential hotspots. The cleaning frequency depends on the panel location and climate conditions of the region. In areas with high dust, acid rain, or pollution levels, more frequent cleaning may be necessary.

Do you offer maintenance even if you did not install the system?

Yes, before starting, we need to ensure everything is correct. If not, the first step would be to provide a corrective budget to solve any detected anomalies.

How do I know when my panels need maintenance?

In most installations, periodic checks and cleaning would be sufficient. However, it is recommended to pay attention to some warning signs that may indicate the panels need maintenance earlier than expected. The best indicator that your solar panels need maintenance is a reduction in energy production. If you suddenly notice that your solar panels are not producing as much energy as they used to, and your electricity bill is increasing, it is a clear sign that you should schedule a service appointment.
