Cloudy weather or a fault?

Porto and the northern coast have more rainy and overcast days than the south of the country, so production varies a lot from week to week. A few signs help tell the difference:

  • Low but not zero production on grey days: usually the weather.
  • Zero production on a sunny day: points to the inverter or the connection.
  • Lower production than in the same month last year, with similar weather: worth an assessment.

Damp and connections

Frequent rain and damp put outdoor electrical connections, junction boxes and cable entries to the test. When moisture gets in, insulation warnings appear or the inverter switches off at certain times, especially in the morning. These need assessing on site, without touching the cables.

How we work in Porto and around

We reply to your request within 48 h. We start remotely and, if a site visit is needed, we arrange it with you.

We serve the whole country through a single contact. If you have access to the inverter app, comparing with last year is a good starting point; if not, we help you see what monitoring can show you.

If the inverter shows an error, see inverter repair.

Frequently asked questions

My system produces little in winter. Is it faulty?

Not necessarily: winter has fewer hours of sun and more cloud. Compare with the same month last year; if the gap is large with similar weather, ask for an assessment.

The inverter switches off on damp mornings. Why?

It may be moisture in a connection or an insulation warning. Don't touch the cables; describe what happens in your request and we look at it with you.

Do you also cover Gaia, Matosinhos or Maia?

Yes, we serve the whole country. The assessment starts remotely and any site visit is arranged with you.

Who carries out the site visit, if one is needed?

A partner crew we work with. The visit is arranged with you, and no work goes ahead until you approve the quote.
