Your home

Your yearly use and price per kWh are on your electricity bill.

A battery lets you use more of your own solar. About batteries
On your bill as “consumo anual”, or add up 12 months. A typical Spanish home uses about 3,500 kWh; a pool or air conditioning adds a lot more.
The energy price on your bill, without tax or the standing charge. Fixed-price tariffs start at about €0.12; the regulated PVPC averaged about €0.20 in October 2026.
Suggested for your use: 4 kWp, about as much solar as you use in a year.
An example cost, not a Go Solar price: €1,500 plus €850 per kWp. Enter your quote if you have one.
Only if you pay Spanish income tax and the system is installed and paid for in 2026. Your gestor confirms what you can claim.
Change the assumptions
Panels facing south at the best angle (PVGIS). East- or west-facing roofs make less.
About 40% without a battery and 70% with one. The rest goes to the grid.
Per kWh, set by your electricity company. Free-market solar tariffs pay about €0.04 to €0.10.

The assumptions

What the estimate is based on

Every figure is shown, with where it comes from, as of November 2026. Change any of them in the estimator above.

  • Output per kWp1,723 kWh a year in Almería

    1,630 in Murcia and 1,629 in Alicante. The best case from PVGIS, the European Commission's solar data: panels facing south at the best angle, with normal losses. Real roofs often make a little less.

  • Used at home40% without a battery, 70% with one

    The share of your solar used as it is made. With a battery, homes typically use 70 to 90%.

  • Electricity price€0.15 per kWh, before tax

    An example between fixed-price tariffs (from about €0.12) and the regulated PVPC (about €0.20 in October 2026). Use the price on your own bill.

  • Surplus credit€0.06 per kWh

    What your electricity company knocks off your bill for each kWh you send to the grid. It is set in your contract, typically €0.04 to €0.10.

  • Tax on your bill5.11% then 21% VAT

    Every kWh you don't buy also saves the electricity tax and VAT on it, so the saving includes both.

  • System costGo Solar prices to confirm

    Until Go Solar publishes its prices, the estimator uses a public example: €1,500 plus €850 per kWp. Enter your own quote for a real figure.

How it works

Four steps from your bill to a payback figure

  1. Solar made

    System size × output per kWp. A 4 kWp system in Almería makes about 6,900 kWh a year.

  2. Used at home

    The share you use as it is made comes straight off your bill at your full price per kWh, plus tax.

  3. Surplus credited

    The rest goes to the grid and is credited at a lower price, against the energy part of your bill only.

  4. Payback

    The cost, less any tax break, divided by what you save in a year.
