Why people here
are going solar more than ever

The cost of electricity is not just going up: it changes without warning. Here we explain what is really happening and why more and more people are taking control.

Why it matters
here in particular

  • Extreme demand

    When everyone switches on the air conditioning at once, the grid comes under strain fast and a small imbalance can turn into a serious problem.

    When everyone switches on the air conditioning at once, the grid comes under strain fast and a small imbalance can turn into a serious problem.

  • An unstable grid

    The grid on the Costa del Sol takes heavy demand peaks in summer, when tourism and air conditioning both spike.

  • Volatile prices

    Seasonal demand, the cost of gas and pressure on the grid cause sudden rises and make your bill less predictable.

  • Rapid growth

    More homes, more demand and more pressure on the system: reliability problems are not going away any time soon.

Zero control

Electricity is no longer a stable expense: tariff changes, peak hours and pressure on the grid mean your bill depends less and less on you.

Self-consumption

70%

Measured, not estimated

Your home,
running on its own energy

Decisions based on data

Decide from your real consumption. Adjust how your home uses energy instead of working blind.

A connected system

Panels, battery and grid work together. Everything is designed as one system, not as separate parts.

Clean generation

Generate your own energy every day. You depend less on the electricity company and stabilise your costs long term.

Flexible control

Adapt the system to your life. Prioritise comfort, savings or backup, whichever matters most to you.

What actually changes

It is not only about saving money. It is about how your home works day to day.

Predictable costs

Your monthly spend stops being a lottery. With your own system you fix a stable base instead of suffering every tariff change.

Visible consumption

You finally see when and how you use energy. Not when the bill arrives, but in real time.

Backup power

If the power goes off, your home carries on. The essentials keep running without interruption.

Less dependence

You rely less on the grid during the hours of highest demand, when both the price and the risk are greater.

Control over use

You decide how and when the energy is used. Store it, shift it or draw less from the grid at peak times.

From an opaque bill to control of the whole house: this is what a properly sized installation on the Costa del Sol costs and what it gives back.

System cost

€4,000–14,000

The usual market range for a turnkey residential installation on the Costa del Sol, before grants and tax deductions.

Payback

4-5 years

The usual payback period on the Costa del Sol, and faster still with the IRPF (Spanish income tax) deduction and municipal tax reductions.

Self-consumption

85%

Average annual self-consumption of a properly sized Sun System installation with a battery. Without a battery the average is around 70%.

Total savings

€32,000

Net savings over 25 years, allowing for equipment degradation and battery cycles, and assuming no rise in electricity prices: if prices rise, you save more.

Most people hold off because they wait too long

They wait for the "perfect moment": lower prices, better grants, more certainty. But electricity does not get simpler with time: it gets more expensive and less predictable.

Costs go up, they do not settle

Waiting means paying more in the long run

The sooner you start, the more years it generates
