The Problem: Energy Bills on the Costa del Sol Have Spiralled
The average 200–300m² villa owner in Marbella, Estepona or Fuengirola pays between €5,000 and €9,000 per year in electricity, oil or gas. With Spanish electricity tariffs 40% higher than five years ago and oil prices tied to volatile global markets, those bills will only keep rising — unless you take control.

Days of sunshine per year in Marbella — enough to power your entire home
Our Solution: High-Efficiency Solar + Heat Pump + Airzone Control
We don't sell a product. We install a complete energy ecosystem that works together to produce more than your villa consumes — turning your electricity bill from an unavoidable cost into near-zero.
High-Efficiency Solar PV
We install premium solar panels with efficiencies above 22% on villa rooftops, covering 12,000–18,000 kWh of annual generation on the Costa del Sol. We handle all paperwork: declaración responsable, CAU registration, Endesa grid connection.
Heat Pump (Aerotermia)
We replace your gas or oil boiler with a Daikin or Mitsubishi heat pump that heats, cools and produces hot water at 350–500% efficiency. For every 1 kWh of electricity it consumes, it generates 3.5–5 kWh of heat.
Airzone Multi-Zone Control
We divide your villa into independently controlled zones managed from your phone. Only heat or cool the rooms you actually use. Additional 30–40% saving compared to single-zone systems.
Battery Storage (Optional)
Stores your midday solar surplus for use in evenings and overnight. DEYE 10–20 kWh batteries guarantee coverage on cloudy days — and keep your villa running during summer grid outages.
"300 days of sunshine a year. Your roof is a power station you haven't switched on yet."
— Ben Hayden, Energy Advisor Marbella

Why the Costa del Sol Is Europe's Best Location for This Investment
300+ days of sunshine
More solar irradiance than almost anywhere else in Europe. Your panels generate for longer and at higher intensity throughout the year.
Bills among Europe's highest
Spanish electricity is expensive. The higher your current bill, the greater your annual saving and the faster your return on investment.
Large villas with high consumption
Pools, 12-month climate control and large floor areas mean high consumption — which means the absolute euro saving is larger.
EPC boosts resale value
The jump from EPC D to EPC A typically adds €20,000–€40,000 to villa resale value. Your German and Scandinavian neighbours demand high-rated properties.
