Solar Panel for Roof
Your roof is the biggest unused energy source your home or business has. Every day, even an overcast British one, it catches enough daylight to power a good share of what you use. All it needs is solar panels.
At Optimum Electrics, we’ve been designing and installing solar panels for roofs since 2011. We’re a Peterborough-based, MCS-certified installer and NICEIC-approved electrical contractor, fitting roof solar panels on homes and commercial buildings across the UK. We design every system around your roof, your energy use and your budget. We don’t sell one-size-fits-all packages.
Wondering whether solar panels are right for your roof, what they’d cost and how much you’d save? Our free roof survey will give you clear answers.
Why Choose Solar Panels for Your Roof?
Putting solar panels on your roof is one of the most effective ways to cut both your energy bills and your carbon footprint. Solar panels run on daylight, not just direct sunshine, so they generate electricity all year round in the UK. They produce the most in spring and summer, and still make a useful contribution in winter.
Here’s why more homeowners and businesses are choosing roof solar panels:
-
Lower energy bills – Every unit of electricity your panels generate is one you don’t have to buy from the grid. Your savings go further if you run appliances, an EV charger or a heat pump during the day.
-
Get paid for what you export – Under the Smart Export Guarantee (SEG), energy suppliers pay you for the surplus electricity you send back to the grid.
-
0% VAT until March 2027 – Solar panels and batteries installed on homes are currently zero-rated for VAT. The rate is due to rise to 5% from 1 April 2027, so now is a good time to install.
-
A lower-carbon home – Solar panels are clean and silent, and they generate electricity right where you use it. That cuts the carbon emissions from the electricity you use.
-
More control with a battery – Add battery storage to use your solar power in the evening, or to charge up on cheaper off-peak tariffs. With the right inverter, a battery can also give you backup power during a power cut.
We don’t just fit panels. We design complete systems (panels, inverter, battery and monitoring) to suit your roof and the way you actually use energy.
Our Expertise — Powering UK Homes Since 2011
Optimum Electrics was founded in 2011 as a local electrical contractor in Peterborough. Since then we’ve grown into a trusted solar installer working across the UK. Our qualified electricians and renewable energy specialists have completed hundreds of solar projects, from family homes to large commercial roofs.
We’re MCS certified, NICEIC approved and HIES accredited, and we were an Octopus Energy Team of the Year finalist. MCS certification matters to you: it shows your installation meets recognised industry standards, and you need it to claim payments under the Smart Export Guarantee.
Every roof is different, so every project starts with a proper roof assessment. Before we recommend a system, we check the roof’s direction, pitch, shading, condition and structure. South-facing roofs pitched at around 30–40 degrees are ideal. East- and west-facing roofs work well too, because they spread generation across the morning and evening, which is often when households use the most power.
You’ll get a clear, jargon-free proposal. It shows what your system will cost, how much electricity it should generate, what you can expect to save and how long it should take to pay for itself. There’s no pressure and there are no hidden costs.
How We Install Solar Panels on Your Roof
Going solar should be simple. Here’s how it works with us:
Free Consultation & Roof Survey
We start with a chat about your property, your energy bills and what you want to achieve. Then we survey your roof, using satellite imagery and an in-person visit where needed, to check its size, direction, pitch, shading and condition.
System Design & Proposal
We use solar design software to plan the best panel layout for your roof and work out how much electricity it will produce. Your proposal sets out the equipment, total price, expected generation, savings and payback period, so you can decide with confidence.
Professional Installation
Once you’re happy, our certified electricians handle the full installation: scaffolding, mounting system, panels, inverter and any battery. All work is carried out to MCS standards and UK wiring regulations. Most home installations are finished within a few days, and we leave your property clean and tidy.
Testing, Commissioning & Registration
We test every connection, commission your system and register it with your local electricity network operator. You’ll receive your MCS certificate, which you need for the Smart Export Guarantee. We’ll also show you how to track your generation using your system’s monitoring app.
Ongoing Support
Every roof solar installation comes with our workmanship guarantee, plus manufacturer warranties on the panels, inverter and battery. If you ever need servicing or repairs, or want to add a battery or EV charger later, we’re only a phone call away.
From your first call to final sign-off, you’ll have one point of contact who keeps you updated at every stage. We think going green should feel personal, not corporate.
Roof Types We Work With
No two roofs are the same, and we enjoy that challenge. We install solar panels on:
Tiled roofs – This is the most common roof in the UK. We can fit panels on-roof, using rails and roof hooks that sit beneath the tiles. Or we can fit them in-roof, where the panels replace tiles for a sleek, flush finish.
Slate roofs – Natural slate needs careful handling. We use specialist slate hooks and fixings that secure the system without cracking slates or weakening your roof’s weatherproofing.
Flat roofs – We use angled frames to tilt the panels towards the sun. These are usually held in place with ballast rather than drilled into the roof, which protects your roof covering.
Metal roofs – These are common on commercial and agricultural buildings. We use clamps and brackets designed for metal sheeting, often without making any holes in the roof.
Green roofs – Living roofs can go solar too, with mounting systems designed to sit on the growing layer. The cooling effect of the plants can even help the panels run more efficiently.
Not sure if your roof is suitable? Most are. If your roof needs repairs, we’ll tell you before installation, because it’s far easier to fix a roof before the panels go on than after. Most homes don’t need planning permission for roof solar panels. If your property is listed or in a conservation area, we’ll check for you.
