A Solar Company Built on Honest Advice
My name is Martin Hill (left). After running a successful hotel business in the Canary Islands, I retired to the Costa Blanca. I always planned to go solar and reduce my cost of living – but quickly ran into the same challenges most expats face: Who could I trust? What’s the best solar choice?
That’s when I found Mariposa Energía, the only British-run solar company in Spain with in-house installers, post-installation support and their own electricity deals.
After seeing my own savings grow, I started helping friends and neighbours through the process.
Before I knew it I was out of retirement and a solar ambassador for Mariposa Energía representing Murcia, Alicante & Valencia.




A New way to Go Solar in Spain
Two major obstacles stop many homeowners from going solar in Spain:
- Getting clear information in your language
- Understanding the best system (and whether you’re being ripped off or missold)
We work in association with Spain’s largest English-speaking solar installer (Mariposa Energía). But we remain independent and whose mission is to find out the best solar choice for you.
With an MSc in Renewable Energy, I take a different approach: making home visits, ensuring you understand the quotation in full, negotiating the best deal on your behalf, being on-site for installations, and remaining your local point of contact for years to come.
