Best Regional Solar Panel Installers Near You (November 2024)

The table below lists some of the best solar companies in the UK:

To arrive at the results, we looked over the offerings of 40 of the most prominent companies in the UK, along with numerous smaller regional installers (regional installers can have their own benefits, providing specialised and cheaper service). It is worth noting that there are upwards of 400 solar panel installers in the region, which means that no one source can give you a definitive rundown of all the companies available.

That said, we ensure a list by developing relevant criteria for top installers, consulting prior research from our older lists, cross-referencing the list of trusted traders on websites like Which.co.uk, and then whittling down the large list of companies that we could compare. We arrived at the following 11 installers, some of which are established names, and others are lesser-known underdogs who deserve attention.

While we cover our criteria in more detail below, the main 3 points we look at are the objective metrics (types of panels, what solar panel manufacturers they work with, efficiency stats, regionality, etc.) reviews, and company history. Each of our picks provide some of the best solar panels for UK homes.

Starting in 2011, Project Solar UK has been a major name when talking about the best choice for UK consumers and it’s easy to see why. They have a number of amazing solar panel models in their catalogue, a potential lifetime warranty offer, and a great score on Trustpilot. The company also operates in multiple regions across England and Wales, with wide coverage and years of solar panel experience.

They also have received acclaim for their extensive coverage across multiple parts of the UK and areas of Wales. While they can be a bit on the pricey side, they provide solar panels from top-of-the-line brands like SunPower and Panasonic. These high-output, high-efficiency models could make the cost worth it, along with the generous warranty offer.

Project Solar also wins in another category:

Project Solar UK’s standout strength is its strong warranty. The company promises a baseline of 85% output after 25 years and then 80% after 30 years post-installation. Considering how long solar panels last, this is a bold warranty that takes into account a far longer time period.

They provide the warranty on panels from companies such as SunPower, Panasonic, and AIKO. Each of these companies has a low annual degradation rate on their panels and offers some very high output models. All in all, this means that your solar panel system will be producing adequate energy for multiple decades.

Project Solar provides the best warranty out of the companies listed. Aside from the warranty itself, another consideration is the high quality of the panels they sell. With high outputs and baseline efficiencies, companies like Aiko or SunPower (while not being the cheapest) can be a great option for long-lasting energy generation.

Founded in 2013, Cahill has been around for a while. One of the striking things about the company is that they operate largely on recommendations rather than a sales department. This has made the company more focused on service rather than marketing and pushing for a purchase, according to satisfied customers on online reviews.

Although they don’t have the highest regional reach, the company is one of the best-reviewed solar installers in South England at time of writing. They have received a 5/5 for customer service on Which.co.uk, along with a 4.8 Trustpilot score, which gives their reputation a lot to live up to. Their reviews page makes clear that customers appreciate the timely installation and generous offers from the company.

Holding all necessary accreditations, overwhelmingly positive reviews, and other accolades, the company’s raving customer testimonials often paint a picture of competence, affability, and professionalism. Cahill Renewables has a great reputation all around.

Beginning in 2010, Evergen comes in as a seasoned veteran in the solar field. They provide a wide range of panels and batteries and have numerous partners within the industry. Along with Porject Solar UK, they may be a great option for installing solar panels in Wales.

Their warranties are protected by the Home Insulation & Energy Systems Contractors Scheme (HEIS), allowing for a 25 year period. They even offer an option to install black solar panels if that suits the aesthetic of your home.

Evergen became our pick for budget solar panels due to their flexible payment options, different price options for new builds vs retrofits, and the wide range of offerings for batteries and panels. The company allows customers to spread the installation costs over several years.

On the map since 2011, Kimble Solar is a smaller but well-regarded company with outstanding ratings among customers. Kimble Solar offers great solar installation at great speeds, garnering major acclaim from various institutions and accreditation organisations. They are known for working with Perlight solar panels.

The company has a whole page dedicated to various types of business-based solar installations they provide. From horticulture to manufacturing to solar farms and much more, they provide for a range of businesses. Kimble also provides a 10-year finance scheme to portion out your payments over time.

With a diverse range of offerings for different businesses, Kimble Solar is popular and has worked with schools. Alongside that, they have also provided high-power solar installations for homes as the case studies on their website highlight.

Solar4Good may not have been around the longest (2024) but they have gained some positive recommendations from various outlets and it’s easy to see why. They are known for having one of the best turnaround times, offering a maximum 10 day work time (while achieving installation in far less usually).

The company provides a wide range of systems with high solar panel efficiency. Their various industry partners allow for a range of options and highest quality installations. They pride themselves on price-matching and offer various packages for homes and businesses of all sizes. They are also one of the best companies for solar panels in Scotland.

As an example of solar panel efficiencies, Jinko Solar panels (one of their partners) offers solar panels with 26.8% efficiency. This is far higher than the industry average 22% to 24%.

While in prior years we would have been tempted to put Project Solar UK in this slot, there are some reasons 2024 has upended its claim to the highest-efficiency solar panels. Providing multiple solar panel manufacturers such as JA Solar panels, Jinko, Trina Solar, Qcells, and Fox ESS, they host many of the best solar panels on the market.

Formerly known as Cornwall Solar Panels, Naked Solar has been around in one form or another since 2010. The provocatively named company has garnered acclaim for steady service, earning a 5/5 from Which.co.uk and a 4.4 on Trustpilot, while also being an Octopus Trusted Partner.

Naked Solar has accrued a number of accolades in their time as an installer. Aside from panels, they are also an accredited Tesla Powerwall battery installer, which allows them to provide better warranties on Tesla’s goods. Alongside that, they provide LG, Byd, SolarEdge, and numerous other models worth considering.

In terms of sheer options for solar battery systems, Naked Solar has a big portfolio. The company’s website lists numerous big-name manufacturers such as Tesla, LG, and more.

We compared a number of subscription services, including Unbound Energy and flexible solar plans from various energy providers. Sunsave is the best reviewed among the options we encountered, despite only being in the game since 2022. Sunsave provides solar panels with a choice between a subscription plan (Sunsave Plus) and a non-subscription, lump sum payment.

Alongside solar panels, the company provides Givenergy inverters and batteries, which are of high quality. They have also branched out to vehicle charger and heat pump installations in recent years, making their offers a complete sustainability package. The company operates in Hampshire, Devon, Kent, Essex, Bristol, Dorset, and a number of other English regions.

Sunsave’s subscription plan can be a great way to pay for better energy systems without excessive upfront solar panel costs. These can be manageable and Sunsave ensures continued monitoring and maintenance help for its customers.

Our research into these companies came from 3 areas: objective metrics, reviews, and company history. In terms of the objective metrics, we look at the warranty they provide, their prices, the solar panels they offer, and other elements of their offers. Whether a company is old enough and what awards they’ve won also help narrow down the choices since longevity and recognition can be indicators of trustworthiness. Conversely, we also included some promising newcomers that stood out.

History

The company's history also involves looking into certifications, awards, and other accolades that might indicate quality. Aside from the social proof this provides, it can also be an indication of what kinds of services they provide i.e., are they better for residential or commercial panels or are they good with customers.

Customer feedback

Consumer feedback and reviews are also very important in assessing a company’s services. As such, our researchers looked into Trustpilot and other available resources that provided testimonials from customers. We also collated the information on this page with other lists of the top 10 solar companies in the UK, providing an outlook that mixes in reviews from professional outlets and newspapers.

Product range

What solar panels they provide are a major consideration. We compare panels using warranties, output ranges, and efficiency. Warranties as high as 25 years can cover the life of a solar panel before degradation sets in, and efficiency rates should be higher than 22%.

Ultimately, the best solar installers in the UK provide a decent range of panels, have years of experience, provide longer warranties, and have great word of mouth from both professional reviewers and customers. Resources like Trustpilot and Which.co.uk can be great resources, along with newspapers.

Regionality may not have as much of an impact. Many large companies let customer service slide while many regional installers provide better prices and personalised customer care. Ultimately, the best UK solar panel company is one which provides your specific needs and those needs can vary.

All this information about solar panel installers can be hard to navigate on your own. That’s why we recommend contacting trustworthy installers in your area and assessing their prices for yourself. However, this may be a daunting task requiring days of research into the installer and government grants for solar panels. That’s why we offer an easier way.
