Solar panels and batteries
Make your own electricity from the Portuguese sun. English-speaking electricians who size, fit and register a solar system, with or without a battery.
Signs you need an electrician
- High electricity bills, especially in summer with air conditioning
- A roof, terrace or garden with sun most of the day
- You want backup when the power goes off
- You have panels that stopped producing, or an inverter showing errors
What the electrician does
- Looks at your bills and your roof, and sizes the system
- Fits panels, inverter and battery, and connects them to the fuse box
- Handles the self-consumption registration (autoconsumo) with DGEG
- Repairs or checks existing systems and inverters
Before the electrician comes
Gather twelve months of electricity bills, or your yearly use in kWh.
Check with the condominium if the roof is shared.
Take photos of the roof, the fuse box and where an inverter could go.
What it costs
Every electrician sends a written price, with IVA, before any work starts. You can compare up to three.
Frequently asked questions
Do I need permission?
Small home systems are registered with DGEG as self-consumption (UPAC); the installer does it. In a flat, the shared roof needs the condominium's agreement. Listed buildings and historic centres can have extra rules.
Is a battery worth it?
It stores the midday sun for the evening and can keep essentials on in a power cut. It adds cost, so ask for quotes with and without one.
How much does it cost?
A 3 kWp system fitted usually costs €4,500 to €6,000 including IVA. A battery adds roughly €2,000 to €4,000.
