The Top-rated Solar Installer in Costa del Sol & Costa Blanca
Marblanc Solar was founded in 2022 by qualified electrician Adam Millington in Marbella.
The company grew rapidly in its first year, driven by a demand for expert solar installers on the Costa del Sol. Through word of mouth, Adam began receiving calls from both homeowners and some of Spain’s best-known solar companies to fulfil their installations. He soon switched to focusing only on Marblanc Solar clients to maintain high-quality after-sales care.
In 2024, certified civil engineer Roman Mitchell joined as co-owner of Marblanc Solar. The combination of Adam’s rigorous installation quality control and Roman’s innovative approach to system design – based on a detailed, free solar survey – proved to be a winning formula.
By the end of 2025, Marblanc Solar had become the top-rated solar installer in Marbella, with more than 100 five-star reviews on Google and Facebook. We then expanded to the Costa Blanca with the opening of our office in Javea.
Marblanc Solar is also frequently mentioned in local media through publications like The Olive Press, Sur in English, Euro Weekly News, The Spanish Eye and more.

Our Solar Installations Services
At Marblanc Solar, we specialise in designing, installing, and maintaining high-performance solar systems.
With every installation, our goal is simple: to help you reduce your monthly electricity bills by 80% or more, while ensuring your system is fully legalised and compliant with Spanish regulations.
Our in-house team fits high-performance solar panels with quality control overseen by certified electricians. We only install the correct and optimal system components – such as cables, optimisers, surge protection devices, energy meters, and solar inverters – ensuring every installation can fulfil our 25-year workmanship warranty.
When needed, we can also design and secure licenses for pergolas or custom solar mounts to complement your property – see an example from a solar installation with custom pergola in Mijas here.
Here’s another example of a custom steel frame we built to mount solar panels on a property that featured on Netflix’s Making it in Marbella series.
As part of our post-installation services, we compare energy providers and switch you to the best solar feed-in tariff and virtual battery deal for your home. We also revisit your property to set up plug timers and ensure you’re getting the most out of your free solar energy.
For clients with an electric vehicle, we also offer EV charger installations, providing a complete, future-ready energy solution.
