best solar roof tiles
What Are Solar Shingles?
Solar shingles, or solar roof tiles, are made of slim photovoltaic (PV) sheets that either overlay or change the existing shingles on a roof. They absorb sunlight and transform it into electricity. By depending on this approach of energy as opposed to electrical energy, for example, property owners will certainly conserve money on monthly costs as well as at some point recoup their preliminary investments.
We now list 15 of the UK’s leading solar roof manufacturers for 2023 for you to choose from
GAIN SOLAR is a leading manufacturer in China specializing in the production of solar shingles. We produce crystalline silicon photovoltaic roofing tiles for buildings to increase the efficiency and resilience of the tile output. Not only do we produce the tiles, but the company also manages every step of the process from design to installation, providing you with professional installation guidelines. These shingles have an attractive texture and their continuous power output is guaranteed. Replace your existing roof with a solar roof with identical monocrystalline solar and non-solar shingles. These shingles are made from tempered glass and come with a 15 year limited warranty. These shingles have TUV certification, carbon footprint certification, ClassA fire rating, as well as CCC, Green Building Material Certification, EN13501 and Green Building Material Rating certification in terms of building material quality to ensure energy output while keeping solar shingles green
This well-known technology brand also manufactures solar shingles. Tesla shingles are made from quartz, which improves their efficiency and resilience. Not only does Tesla create the shingles, but the company also manages every step of the process, from design to installation, which includes the removal of the current roof, if applicable. These shingles come in attractive textures, and they come with a 30-year power output warranty. An app allows you to monitor your shingles’ energy levels at a glance.
About: The Tesla solar roof replaces your existing roof with identical monocrystalline solar and non-solar tiles. The tiles are made of tempered glass and claim to be “three times stronger than standard roofing tiles,” and are equipped with a 25-year limited warranty. These shingles have an ASTM D3161 Class F wind rating, which means they can withstand winds up to 110 mph. The Tesla solar roof also has a Class A fire rating, which means they are least likely to spread fire rapidly (similar to standard home-building materials).
CertainTeed solar shingles are created with the same monocrystalline technology used for solar panels. There are two designs, one that coordinates with concrete tile roofs and another that matches with asphalt.
About: The CertainTeed Solstice solar shingles come in a stock size of 14 all-black monocrystalline cells (70 watts per shingle) with a standard 25-year limited-power warranty. The shingles are positioned on an existing roof and include water channels to guard against leaks. CertainTeed solar products only work with asphalt shingle roofs, so owners of wood, metal, or tile roofs may want to look elsewhere. The installation warranty length depends on the CertainTeed-credentialed installer’s rank, as outlined in the warranty section of the Solstice shingle spec sheet.
SunTegra is another option for those looking for a more budget-friendly option in solar roofing. Its simple, lightweight configuration reduces the time it takes to install and integrates well with either asphalt or concrete roofs.
About: SunTegra Solar Tiles are installed without racking for a sleek appearance on your roof. The tile’s lightweight design needs 50% fewer parts than conventional solar, is installed quickly, and may let you avoid extra building permits. These solar roof shingles have a 25-year limited power and a 10-year limited product warranty.

6. Timberline Solar by GAF Energy
About: Timberline Solar shingles are available solar energy shingle designed for fast installation. Like the Tesla solar roof, the Timberline shingle replaces your roof. Therefore, the overall price is higher since you get two products: a new roof and solar technology. These waterproof shingles are the largest single-unit shingle and can withstand winds up to 110 mph. Timberline Solar shingles come with a 25-year warranty.
7. XO Edge
London-based XO Edge says it can install its sleek-looking black and silver tiles on your roof within eight weeks of purchase.
Each tile only generates 12 W, which means you'll need around 13 tiles per square metre – though at just 1.4 kg each, they're very light.
XO Edge hasn't yet responded to our enquiry about price information, but we'll update as soon as it does.
8. Marley SolarTile
Marley describes its product as a tile, but it's really just a solar panel that's completely integrated with your roof, so it's flush with your roof tiles.
Each 'tile' generates 335 W at an efficiency of 20.7%, making it a decent but average solar panel.
The company offers a 15-year product warranty, which isn't bad, and a 25-year performance warranty that also isn't pulling up any trees.
If you desperately want panels to be inserted into part of your roof in place of tiles, choose Marley.
Solecco tiles may be a good alternative to waiting for Tesla, as they offer attractive black or terracotta roof options. We are still waiting to get pricing and availability information from Solecco.
10.GB-SOL solar tiles
GB-SOL, located in Pontypridd, Wales, sells solar tiles in just the one style – “natural blue” slate, to complement a slate roof.
They’re lighter than traditional tiles (just 3.5kg per slate), which means you could replace your roof without having to strengthen your property’s structure.
A GB-SOL solar slate can generate 28 W of power, and has a 25-year warranty on the product, its solar performance, and its weatherproofing abilities.
The tiles sell for £294 per square metre, which adds up to £8,449 for a 4 kW system – though that's without installation, which will typically add another £2,200. That means you'll pay a total cost of £10,649.
11. Solecco Solar
Solecco Solar, based in Leeds, manufactures and sells solar tiles for £3000/kW, which means that a 4 kW system will cost you £12,000.
It also usually costs an additional £1,000 to have the tiles installed, according to the company.
Though its product is more expensive than some, Solecco Solar does offer tiles in eight different colours, from smooth grey to terracotta and old English dark red.
And if you don't need or want to buy solar tiles to cover your whole roof, you can purchase the company's identical (and cheaper) non-solar tiles to make up the difference.
12. Solarcentury solar tiles
This one’s nothing more than a history lesson. The UK-based Solarcentury used to sell solar tiles (the C21e range), but these have since been discontinued. Instead, the company now produces integrated solar panels – the Sunstation Roof-integrated+ – which aren’t quite as subtle as solar tiles, but still sit more seamlessly on your roof than standard solar panels.

Their solar tiles are robust and engineered to withstand winds of up to 266 km/h, boasting a fire rating of BAL-40 and shatter resistance that can withstand 65 mm hail.
What happens if I generate more solar power than I use?
If you generate more than you consume, you can feed it back to the electricity grid, for which you receive a compensation. This makes the netting arrangement in the Netherlands possible.
If I get a fire from my solar panels, what should I do? Is the installer liable?
The chance that a fire will start due to a solar power system is very small (0.0023%). Who can be held liable in such a case differs per situation. If it turns out that the installer has been negligent in the installation of the solar panels, the installer is liable. If you have solar panels installed, it is wise to take out building insurance.
Is it best for me to put solar panels or solar collectors on my roof?
The main difference between solar panels and solar collectors is that solar panels are used to generate electricity using the sun. A solar collector captures the heat from the sun and transfers this heat via a pipe system to a solar boiler. It just depends on what you would like to make more sustainable, the electricity or hot water. You can of course also choose both options.
If I have solar panels installed, can I also use them in the winter?
Solar panels use the light from the sun to produce electricity. Every day it gets light and the sun shines every now and then, so your solar panels also provide energy in the autumn and winter period. In these months, less is generated compared to the spring and summer months.
