Expert Solar Battery Installations on Spain’s Costa del Sol and Costa Blanca

At Marblanc Solar, we install solar batteries across the Costa del Sol and Costa Blanca regions in Spain. Whether you are starting from scratch or upgrading an existing setup, we provide a path to total energy independence through our Free Solar Survey.

The survey uses precision drone scans, local climate data, and your actual electricity usage to create a comprehensive proposal – integrating solar batteries, EV chargers, and backup boxes. To ensure you invest with confidence, we provide side-by-side comparisons showing your home’s projected performance and ROI both with and without a battery.

Retro-Fitting Solar Batteries?

If you already have solar panels, we can retro-fit solar batteries to existing systems. Just contact us for a technical compatibility check to see if your current inverter can handle an upgrade.

Cut Your Electricity Costs to €0 with a Properly Designed Battery System

Too many homeowners are sold battery systems by sales reps who don’t understand load curves, nighttime consumption or inverter compatibility. You’re shown unrealistic savings projections, given a generic quote and then left disappointed when the system underperforms. The result? A battery that looks impressive on paper but doesn’t deliver in real life.

We believe a battery system should be engineered around your real consumption data – not guesswork.

A Performance Promise You Can Trust

Our “performance promise you can trust” is built on a structured, data-led proposal process designed to eliminate guesswork and inflated projections.
