25-Year Workmanship Warranty
We provide a 25-year workmanship warranty agreement for all our solar energy installations. This is in addition to you 25-year equipment warranties, and means we’re responsible for the proper functioning of your system as promised.
Professional System Design
A qualified survey engineer visits your property, conducts a precision drone scan, and models your roof geometry, shading, orientation, and seasonal variation using the world’s leading solar design software. Every proposal built on real data – not a salesperson’s estimate.
In-House Team
Every stage of your installation is carried out by our own qualified electricians and survey engineers – no subcontractors, no handymen. Cables are hidden from view as standard, penetrations are plastered over, broken tiles replaces, and your property left exactly as we found it.
Equipment Specialists
We are official partners and registered installers for the world’s leading solar brands – including Huawei, Enphase, Fronius, Tesla, and SolarEdge. Our team undergoes regular training and are experienced in installing the best equipment on the Spanish market.
System Upgrades
Solar panels are often just the starting point. We can install EV chargers, solar batteries, backup boxes, and project manage plumbing-based systems such as heat pumps and pool heaters. We build pergolas and ground-mounted steel frames if your roof isn’t the best option.
Aftersales Care
Every client receives three years of aftersales support as standard – including remote performance monitoring, direct WhatsApp access to your engineer and our co-owners, annual service, annual panel clean, and emergency callouts seven days a week. Backed by our 25-year workmanship warranty.
Getting a trustworthy proposal for a commercial solar installation is harder than it should be
For residential solar, a slightly optimistic quote is frustrating. For a commercial installation, it can be costly. The solar arrays are larger, the batteries more substantial, and the consumption figures more complex. The margin for error is smaller and you can’t afford to invest in a system that fails to deliver on its promises.
The problem is that too many solar proposals are built on estimates plucked from the air. A salesperson takes a look at the roof and comes back with figures that aren’t grounded in a proper assessment of your building, your electrics, or your actual consumption patterns.
You deserve a commercial solar installation proposal you can trust. The savings need to be real, the system needs to be sized correctly, and the installer needs to be qualified to deliver on what they’ve promised.
Marblanc Solar’s free solar survey is the professional process that makes a trustworthy commercial proposal possible for business on Spain’s Costa del Sol and Costa Blanca.
Why you can't trust a standard solar proposal – and what we do differently
Most solar quotes are produced by salespeople working from assumptions. What they won’t do is inspect your electrics, model your system against real shading and orientation data, or run a performance simulation based on your actual usage. For a commercial installation, where the numbers are bigger and the stakes higher, that kind of proposal isn’t good enough.
We believe you deserve a solar proposal that delivers on its promises. That’s why at Marblanc Solar we employ qualified survey engineers and electricians to prepare a proposal, via our Free Solar Survey.
Our solar survey process gives you €250 worth of free value* that includes:
- Drone scan of roof and property
- Inspection of home electrics by a qualified professional
- Thorough Q&A about past electricity usage & desired consumption in future
- Professional solar design factoring in shading, orientation & seasonal change
- Performance simulation with the world’s leading solar design software
- Payback period & ROI calculations
- Itemised quote and system comparisons
Our Story
When Adam Millington founded Marblanc Solar out of our Marbella office in 2022, he'd already spent years working as a qualified electrician on the Costa del Sol. He'd seen first-hand what happened when solar systems were sold by people who didn't understand electricity. Undersized arrays. Incorrect inverter configurations. Customers who'd been promised 70% savings and were still opening €200 electricity bills.
The problem wasn't the technology. Solar works. The problem was the process – and the people delivering it.
Our mission
Adam realised the need to build a company where qualified professionals handle every stage. Not salespeople. Not local handymen. Not subcontractors brought in from wherever was cheapest that week. Qualified electricians and certified survey engineers – in-house, on every job.
In 2024, certified survey engineer Roman Mitchell joined as co-owner. He brought with him a rigorous approach to system design and a commitment to solar proposals that can deliver on their promises. Together, they developed the Free Solar Survey: a process that uses precision drone scans, local solar radiation data, and the world's leading solar design software to produce a system design specific to your property.

Aftersales care built for commercial clients
Getting the most out of a commercial solar installation doesn’t end on the day the system is switched on. For commercial clients, the period after installation is often where the real optimisation happens – and it’s where many installers fall short.
Marblanc Solar’s aftersales care package is included free for three years with every installation, and it’s valuable for commercial clients.
- Through remote consumption monitoring, we can see exactly how your system is performing and identify opportunities to improve your savings.
- Your direct WhatsApp channel gives you 24/7 access to your survey engineer, project manager, and Marblanc Solar’s co-owners for any questions or issues that arise.
- Our annual servicing ensures your system continues to perform at the level your proposal promised.
Beyond the basics, our team will work with you on the details that make a real difference to a commercial installation – comparing feed-in tariff deals to ensure you’re getting the best return on excess energy, advising on usage optimisation to align high-consumption activity with peak solar production, and recommending practical measures like plug timers and smart scheduling to keep your consumption figures where they need to be.

Can Marblanc Solar help us get the most out of our system after installation?
Yes – and for commercial clients, this is often where the biggest gains are made. Through our aftersales care package, included free for three years with every installation, we provide remote consumption monitoring, 24/7 access to your survey engineer and co-owners via a direct WhatsApp channel, emergency callouts, and annual servicing. Beyond that, we actively support commercial clients with feed-in tariff comparisons, usage optimisation advice, and practical recommendations to align your highest-consumption activity with peak solar production hours. Getting the system right is step one – making sure it keeps delivering on its promises is what our aftersales care is built for.
How long does it take to see a return on a commercial solar installation?
Payback periods vary depending on the size of your system, your energy consumption, and the feed-in tariff arrangements in place for any excess energy your system exports. These figures are calculated as part of our free solar survey using real consumption data and performance simulations – so rather than giving a generic estimate, we’ll give you a payback period and ROI projection specific to your property and usage. Commercial installations tend to benefit from faster payback periods than residential systems due to higher daytime consumption aligning more closely with peak solar production hours.
Is Marblanc Solar’s free solar survey suitable for large commercial properties?
Yes – our free solar survey process is designed to handle installations of any size and complexity. For commercial properties, we carry out a full drone scan of the roof and building, a qualified inspection of your electrics, and a thorough Q&A covering your past electricity usage and future consumption requirements. We then model the system using Pylon, world-leading performance simulation software, to produce payback period calculations, ROI projections, and an itemised quote with system comparisons. The result is a proposal built on real data – not assumptions – regardless of how large or complex your installation is.
