Symptoms
01 — Common problems

What's worth knowing about solar panels.

What's usually behind each symptom and what you can check yourself while the technician is on the way. Without touching anything inside.

Is it worth it in my home?

It depends on the orientation of the roof and any shade on it, the space available and at what times of day you use electricity.

In the meantime · Keep a recent electricity bill to hand; it makes the calculation much more accurate.

I have little roof space or some shade

A good assessment decides how many panels fit and where to put them so that shade affects them as little as possible.

In the meantime · Take photos of the roof at different times of day if there are trees or buildings nearby.

Panels for a residents' association

Shared self-consumption lets neighbours split the energy produced. The residents' association has to agree; if we do the installation, we take care of everything.

In the meantime · Ask the property manager for the roof plans.

They produce less than before

Dirt on the panels, an inverter with errors or a new source of shade can lower production.

In the meantime · Check the inverter's app or display and take screenshots of the last few months.

What about batteries?

Batteries store what's left over during the day so you can use it at night. They're not always worth it: it depends on your consumption.

In the meantime · Note what you use at night: oven, washing machine, electric car…

Paperwork and procedures

The installation has to be legalised and, if you export to the grid, set up for surplus compensation with your electricity supplier. If we do the installation, we handle all the paperwork.

In the meantime · Keep the invoices and the installation certificate.
