Use the Solar Break Even Calculator and See if You Could Recover Your Installation Costs in Just 3-5 Years

Worried about the rising cost of energy?

You’d be interested to know we’ve had clients reach break even on their solar panel installation in just 3-5 years…and it’s actually thanks to inflation.

You see, the cost of electricity in Spain rose from 50-60€/kWh in 2020 to 110-140 €/kWh during the energy crisis in 2022. This meant anyone with a solar panel installation saved twice as much as normal.

Energy experts predict another crisis will hit between now and 2027 while Spain relies heavily on foreign imports of liquified natural gas (LNG).

The solar savings calculator below is the only one in Spain that estimates your break even by factoring inflation in.

But there are 4 more factors to be aware of.

4 Extra Factors Included in this Solar Calculator
  1. You’ll reach break-even faster the more you’re currently spending on electricity (this solar calculator asks you for the € amount of your latest bill and uses this as the basis of the estimation)
  2. You’ll need to sign up to the new ‘virtual battery’ which allows homeowners to cut the fixed costs and charges in their bill down to €0 each month (this solar calculator is the only one in Spain to let you choose between factoring in €0 bills or not)
  3. To achieve a €0 monthly bill you may require 1-3 extra solar panels to sell enough kWh to the grid (if you select €0 bills this calculator will factor the extra costs of additional solar panels into the calculation)
  4. You could save up to €3,200 and over with government solar incentives (there are still incentives available in 2024 depending on where you live in Spain, your property status and your tax residency status – the solar calculator will ask you about each of these for an instant estimation)

With the right optimisation, the right installation and the right electricity provider we’ve had clients earn credit each month and recover their costs even faster.

How to Use the Solar Break Even Calculator

How long does the calculator take?

There are 4 steps which should take no more than 1-3 minutes to answer.

The result is generated instantly.

What do I need to use the calculator?

You need a copy of your latest electricity bill in Spain to hand.

The Solar Break Even Calculator asks for your electricity consumption (in kWh) and bill amount (€).

This is calculate your current electricity costs (€/kWh) and produce a break even estimation result.

You will need a bill from the last 6 months.

What if my electricity consumption is low?

The calculator does not work for properties consuming under 300 kWh per month – or paying under €50-60.

This is because the break even or payback period is significantly longer.

The Solar Break Even Calculator is ideal for properties paying more than €100-150 per month in electricity bills.

What if my my property is a new-build or new home?

The Solar Break Even Calculator uses your existing electricity consumption to calculate your break even.

It will not work if you have no electricity bill yet in your property.

How accurate is the Solar Break Even Calculator?

The Solar Break Even Calculator is the most accurate solar calculator in Spain.

This is because:

  • It uses localised climate data to estimate the system size you need (in kW)
  • It uses recent quotes in your area to estimate the break even for systems of the same size
  • It provides two break even results: based on your electricity savings alone and based on your electricity savings + government incentives factored in
  • It estimates your annual savings based on your current electricity costs (€/kWh) with your current provider
  • It accounts for extra solar panels necessary to sell electricity to the grid and reduce your bill to €0 per month – allowing maximum savings It estimates your 10-year savings based on an inflation rate of 1.9% (the average inflation in Spain over the past 10 years)
  • It accounts for a slight and normal decline in the output of your solar panels over the next 10 years
