Remote Performance Monitoring
For the first two weeks after your installation, we monitor your consumption before making recommendations to maximise your savings. After that, monitoring stays on so that whenever you have a question, we can access your data from our office.
Direct WhatsApp Channel
A 24/7 line to your survey engineer, project manager, and Marblanc Solar’s co-owners. No call centres, no ticket systems – just the people who know your system personally.
Emergency Callouts
If your system develops a fault that needs urgent attention, we dispatch one of our in-house qualified electricians as quickly as possible. No arguing about responsibility. No waiting weeks for a response.
Annual Service
A thorough annual inspection of your installation carried out by our in-house team, to make sure every component is working correctly and your system continues to deliver on its promised savings.
Virtual Battery Switchover
We compare electricity providers and switch you to the best available virtual battery deal – so your excess solar energy earns you credit rather than going to waste. We also have access to exclusive rates not available on the open market.
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.
Heard horror stories about solar installers disappearing?
Every week, Marblanc Solar receives at least one call from a homeowner on the Costa del Sol or Costa Blanca whose solar installer has vanished. No answer on the phone. No response to emails. No one taking responsibility when something goes wrong.
Most often, the original installer was a local handyman or freelancer – not a proper business with the structure, team, or accountability to support clients after the job was done. But you’d be surprised how often it happens with larger, nationwide installers too. Many depend on local subcontractors to carry out the physical work. When a fault develops or a question arises, neither the subcontractor nor the installer wants to own the problem – and the homeowner is left in the middle, going in circles.
When Marblanc Solar started out, we made it our mission to build an in-house team and deliver aftersales care that completely eliminates this situation. Every client has a direct line to the people who installed their system. And we’re still there when they need us.
Real-life Examples of promises delivered
Marblanc Solar offers our clients a 25-year workmanship warranty on top of standard equipment warranties. We stand behind our work and deliver on our promises of how much you'll save.
See real-life examples of bill savings achieved below.
Delivering 8% Further Savings As Promised
This client in Marbella had a monthly bill of €3,309 in August before going solar. We promised an 87% reduction but the client’s bill only fell 79% to €700 a month. We returned again to install plug timers and find a better solar feed-in tariff – as a result, the client’s bill fell to €432 and the 87% promise was delivered.
A Sunday Callout for an Inverter Fault – Resolved the Same Day
A client in Marbella contacted us through their direct WhatsApp channel after their solar inverter began shutting down and throwing an error code. We sent our nearest in-house qualified electrician round that Sunday. The fault turned out to be a ground fault related to their electric gate rather than the panels themselves – but we provided the assistance regardless. Same day, in-house, no argument about whose responsibility it was.
Battery Added Months Later, Bill Down to €30
A homeowner in Sotogrande had 33 solar panels installed with us but wasn’t ready to invest in a battery straight away. We built the system from the outset to allow an easy battery upgrade when the time came. A few months later the client called – we installed the battery, and their August electricity bill dropped from €817 to €30.
Why unreliable tradespeople are Spain's biggest solar problem
We’re yet to meet a homeowner on the Costa del Sol or Costa Blanca who hasn’t had a bad experience with a tradesperson. Often it starts small – a technician arriving later than expected, or not arriving at all. But the stories get worse. Installers who complete the job and then become unreachable. Homeowners left in a frustrating cycle of unanswered calls and ignored emails, with a system that isn’t performing and no one willing to take responsibility for it.
It’s one of the most common reasons people come to us – not for a new installation, but because they need someone to fix or support a system that another company walked away from.
This is why Marblanc Solar created a comprehensive aftersales care package. It’s available to anyone for €400 per year – but for every Marblanc Solar client, it’s included free for three years after installation. It covers:
- Remote consumption monitoring, so we can see the power you’re using and suggest ways to maximise savings with your current system
- A direct WhatsApp channel with your survey engineer, project manager, and Marblanc Solar’s co-owners – available 24/7 for any questions
- Emergency callouts for any faults with your solar installation that need an urgent fix
- Free annual servicing of your installation
- Free annual solar panel clean during months of calima rain or pollen
What Clients Say About Our Aftersales Care Services
Marblanc Solar is committed to delivering on its promises through our aftersales care. But don't just take our word for it.
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.

Our 25-year workmanship warranty
You may be thinking that aftersales care packages are just pretty words on a page. We understand the scepticism – the solar industry has given homeowners plenty of reasons for it.
But during your Free Solar Survey, you’ll see something that sets Marblanc Solar apart: our 25-year workmanship warranty. This isn’t a standard manufacturer’s guarantee on the equipment. It’s a rare legal agreement that makes Marblanc Solar directly responsible for the proper working of your system for 25 years. Not the manufacturer. Not a subcontractor. Us. It’s the clearest possible proof that we don’t just make promises – we’re legally bound to keep them.
Aftersales Care Services
Everything to know about our aftersales care
See answers to the most common questions about our aftersales care services. If you have a question that isn’t answered here, please contact us.
What does remote consumption monitoring actually do?
Remote consumption monitoring allows our team to see exactly how your solar system is performing in real time – how much energy your panels are generating, how much your home is consuming, and how efficiently your battery is charging and discharging if you have one. If we spot anything that suggests your system isn’t performing as it should, or if there are changes you could make to maximise your savings – switching the timing of high-draw appliances, for example – we’ll flag it directly through your WhatsApp channel.
Can I get the aftersales care package if my system was installed by another company?
Yes – our aftersales care package is available to any homeowner on the Costa del Sol or Costa Blanca for €400 per year, regardless of who carried out the original installation. If you’ve been left without support by your original installer, or simply want the peace of mind of having a qualified, in-house team behind your system, get in touch and we’ll discuss what’s involved.
What happens if my solar system develops a fault?
If your system develops a fault, you contact us directly through your dedicated WhatsApp channel – available 24/7. We’ll assess the issue remotely where possible, or dispatch one of our in-house qualified electricians for an emergency callout if needed. Because we use an in-house team rather than subcontractors, there’s no confusion about who is responsible. We are – and our 25-year workmanship warranty makes that a legal commitment, not just a promise.
Is the aftersales care package really free?
Yes – for every client who installs a solar system with Marblanc Solar, the aftersales care package is included free of charge for three years from the date of installation. After three years, it’s available to continue for €400 per year. The package includes remote consumption monitoring, a direct WhatsApp channel with your survey engineer, project manager and co-owners, emergency callouts, free annual servicing, and a free annual panel clean during calima or pollen season.
What to expect when you get a free solar survey from Marblanc Solar
Marblanc Solar offers all interested clients a Free Solar Survey.
Once we receive your details, a qualified survey engineer from our team will arrange a home visit at a convenient time. We then follow a series of steps to design a high-quality system that delivers on its promises.
1
Book Your Free Solar Survey
A qualified electrician or survey engineer visits your property, conducts a precision drone scan of your roof, checks your intake and analyses your actual electricity usage. There's also a thorough Q&A process.
2
We Build Your Proposals
Your survey engineer models your roof geometry, shading, orientation and seasonal solar variation using the world's leading solar design software. We size the system to hit your savings targets, determine the optimal panel layout, and produce a fully itemised proposal.
3
Proposal Presentation
Your survey engineer contacts you within 48 hours for a second site visit to present the proposal. You can ask for instant adjustments on the spot – adding or removing panels, switching equipment or modelling a battery. Everything updates in real time.
4
Decide With Confidence
Take as long as you need. No pushy follow-up, no obligation to proceed. Most clients leave their presentation with two clear options and everything they need to make the right decision – you can keep the drone footage too!
