Step 1 of 5

We need two figures from your electricity bill. We’ll show you exactly where to find them.

📋 Look for this consumption graph on your bill:

① Monthly consumption (kWh)

Look at the bars on the chart. Pick the highest one or estimate an average.

② Monthly bill (€)

What you pay for electricity each month. If you don’t know the exact amount, give an approximate figure.

Enter your details:

Average monthly consumption (kWh)

The highest month on the chart, or an average of the bars.

How much do you pay per month? (€/month)

Your monthly electricity bill (approximate).

If you don’t have the figures, you can still continue.

What type of property do you have?

Property type

This affects the space available on your roof and the type of installation.

Do you have a pool?

Pools with pumps and heating significantly increase electricity consumption.

Do you have or plan to get an electric vehicle?

Where is your property? This determines the tax benefits available to you.

Location

The IBI (property tax) discount varies by municipality.

Annual IBI (property tax) amount (€)

IBI is the Spanish property tax. It appears on the receipt you pay to the town hall (typically between €400 and €1,500/year).

Would you like to include a solar battery in the estimate?

Solar battery

The battery stores daytime energy for use at night. It increases self-consumption from 40-50% to 70-85%.
