The Algarve is one of the sunniest regions in Europe. We explain, plainly, how much a self-consumption system can cut from your bill and how long it takes to pay off.
Why the Algarve is different
The Algarve gets, on average, more than 3,000 hours of sun a year, numbers the rest of Europe rarely sees. For anyone living or working in Lagoa, that means a solar panel produces a good deal more here than it would in the north of the country or in central Europe. The maths is simple: more hours of sun give more production and a lower bill.
At the same time, the price of electricity has risen sharply in recent years. It is the combination of these two factors, plenty of sun and expensive energy, that makes self-consumption so appealing in this region.
What self-consumption is, in plain terms
Self-consumption means producing your own electricity and using it on the spot. During the day, the panels directly power whatever is switched on, such as the fridge, the pool pump or the air conditioning, and you only draw from the grid when production falls short.
- You produce during the day and use it immediately, paying the grid less.
- Any surplus can be fed into the grid or stored in a battery.
- You don't have to leave the grid: it stays as your backup at night and on cloudy days.
How much you can save
Savings depend on your consumption profile, but there is a pattern: the more electricity you use during the day, the more you get from the panels. A family at home in the afternoon, a small business working daytime hours, a villa with a pool and air conditioning: these are the cases where the return is greatest.
In practice, it is common to see the energy part of the bill drop by 40% to 70%, depending on how the system is sized and on your habits. The trick is to size the system for what you actually use, rather than installing the biggest one you can.
How long it takes to pay off
With current electricity prices and the production you get in the Algarve, most well-sized self-consumption systems recover the investment within a few years. After that, the energy you produce is, in effect, free, and panels last 25 years or more.
It is worth avoiding rule-of-thumb maths. A good quote starts from your real bill and the orientation of your roof, not from a generic table.
Batteries: do they make sense?
A battery stores the energy you produce in excess during the day so you can use it at night. It increases your independence from the grid, but also the upfront cost. It makes most sense for those who use a lot of power in the evening or want protection against outages. For other profiles, it can be worth starting without one and adding it later.
Where to start
The first step is simple and costs nothing: an assessment of the site and your bill. We look at the roof's orientation and pitch, the space available and your consumption, and only then propose a solution.
