We review our lineup of solar panels included in this guide on a monthly basis to ensure we’re accurately reflecting what is available on the UK market. To select the solar panels we review, we compare the solar PV panels offered by each of the best solar installers, and we score them based on the following criteria, awarding them points based on a sliding scale:
All data is correct as of March 2026. Our team regularly updates this list with newly-released, more efficient solar panels from selected manufacturers.
The Project Solar Evolution Max 500W is the most efficient solar panel on our list, with a whopping 25.5 per cent efficiency. Combine this with a relatively high power output of 500W, and you get a panel that will consistently perform well in terms of energy production.
When we asked over 2,000 solar panel customers to rate how their system had met their expectations in terms of energy production, cost savings, maintenance requirements and ongoing costs*, Project Solar topped 3 of the 4 categories, giving it the best customer satisfaction score of the providers we reviewed.
The Project Solar Evolution Max 500W comes with limited lifetime product and performance warranties – in comparison, the industry average is around 20 years and 30 years respectively. In practice, what this means is the manufacturer is committed to repairing, replacing or refunding your solar panel if it is defective, provided it has been installed professionally and used correctly. The warranty does not cover the cost of removing defective panels or reinstalling the potential new ones. As for the performance warranty, the manufacturer will send additional modules or provide compensation should the power output drop below 95 per cent in the first 12 years of ownership, 90 per cent in the first 25 years, and more than 3W per year after that.
Project Solar is slightly let down by its lack of sustainability credentials or commitments, and by the high price of its solar panels.
The Trina Vertex 505W combines a high power output and decent efficiency rating of 22.7 per cent in a budget panel which will set you back less than £100 per solar panel.
The Trina solar panel has a dual glass design, which means it is less susceptible to cracks and scratches. As such, it’s well suited to harsher environments including seaside areas, where salt and sad can affect the performance of solar panels.
We also love that Trina is very committed to reducing its environmental impact, providing recycling information and initiatives to make sure its solar panels are being recycled properly. The company is also dedicated to reducing its water and energy use in the production process.
If you live in the warmer parts of the UK, REC might be the best PV panel for your household. At -0.24 per cent per °C, it has the lowest temperature coefficient of all the panels we’ve reviewed, so it’ll be efficient even in warmer temperatures.
Where REC really shines is through its customer satisfaction. At 92.3 per cent, it is second only to Project Solar, and scored particularly well when we asked solar panel owners about their satisfaction with the brand’s cost savings and energy production.
If you use an REC-certified solar installer who registers your panels with the provider, you can increase the product warranty on these panels to 25 years, bringing it in line with the labour warranty.
The Perlight 515W Double Glass BLK Transparent solar panel is one of the most powerful panels in this guide in terms of output, clocking in at number two behind the JA Solar JAM60S4 LR 530W.
It also has a good efficiency rating of 23.17 per cent and is backed by solid, above average 30-year product and performance warranties. Perlight has great sustainability credentials: it won the Ecovadis Bronze Corporate Social Responsibility Medal in 2024, indicating it is in the top 35 per cent of companies evaluated by Ecovadis.
On the downside, the panel is on the heavy side, weighing in at 27 kg, so it may not be suited to every roof.
With an efficiency rating of 23.5 per cent, the AIKO Neostar 3P54 470W is the second most efficient solar panel in this guide. This solar panel also performs well in warmer weather thanks to a better-than-average temperature coefficient of -0.26 per cent. In other words, for every 1°C above 25 degrees, the AIKO loses 0.26 per cent of its power output.
The Neostar 3P54 is also the lightest panel we reviewed, and one of the smallest in this guide. As a result, it is well suited to older roofs, and you might be able to put more of them on your roof than heavier panels.
Neostar panels now feature partial shading optimisation, so if your roof isn’t always in full daylight – which might be the case if you live in semi-detached housing, or in a city with several buildings around yours – the panels will work harder to maintain their efficiency.
However, when it comes to customer satisfaction and sustainability scores, AIKO doesn’t perform so well. While it is high at 90.7 per cent, the brand has the lowest customer satisfaction rating of the providers we feature. It also fails to meet most of the environmental and ethical requirements we look for in our solar panels.
While all solar panels are technically a sustainable choice as they reduce your household’s reliance on non-renewable energy, some panels are better for the environment than others.
As a company, Jinko Solar has some of the best green credentials compared to its competitors. For instance, it is committed to the RE100 and EP100 initiatives, meaning it has pledged to use 100 per cent renewable energy for global operations by 2025, proving the company’s dedication to sustainability.
The Jinko Tiger Neo 54HL4R-B 445W is a solid all-rounder of a panel, but we wouldn’t say it is particularly strongly in any field. That said, it’s one of the lightest and most compact panels in this guide, and it is backed by strong 25- and 30-year product and performance warranties, so it’s well worth considering.
A high power output of 530W means you’ll need fewer of these JA Solar panels to meet your energy needs than other panels. However, this solar panel is also one of the least energy efficient on this list, so you may be better off opting for a less powerful panel with a better efficiency rating in the long run.
This panel is also one of the heaviest and biggest we reviewed, so you’ll need to check your roof has the space and structural integrity required to accommodate them.
According to our survey*, 91.9 per cent of JA Solar customers reported being satisfied with their solar panels. The company also has excellent sustainable credentials, as it recycles solar panels and uses recycled materials to produce its own panels.
When it comes to Suntech, there’s a lot to recommend. The Suntech Ultra V Pro Mini 460W has a good efficiency rating of 23 per cent, and the brand boasts very positive customer satisfaction ratings for maintenance requirements and ongoing costs.
While it’s not actually the smallest panel on this list, it’s the most compact panel with the highest power output, meaning you’ll need fewer of them to generate similar amount of energy to competitors. So if you’re looking to maximise your energy generation and you’ve got limited space, look no further.
However, the company is let down by a relatively short product warranty of 15 years, and lacklustre sustainability credentials. Suntech solar panel owners were also the least satisfied by their cost savings, according to our survey, with 90 per cent of customers saying it met or exceeded their expectations compared to an average satisfaction rating of 92 per cent.
The perfect panels for you will depend on your household’s priorities, budget, location and roof space. Below, we’ve listed what we think are the most important factors to consider when choosing your system, based on what we at the FMB look for when we carry out our solar panel reviews.
A solar panel’s efficiency essentially corresponds to how well a panel can capture and convert daylight into usable electricity. Domestic panels typically achieve an efficiency of 17 to 24 per cent. The best panels on the market, such as Project Solar’s Evolution Max 500W, have efficiency rates above 25 per cent.
A solar panel’s power output – measured by its PMax, expressed in Watts – represents the amount of energy it can supply to your home in optimal conditions. As a reminder, the more power you generate through your system, the more you can reduce your reliance on grid-supplied electricity, or even do without it entirely.
The total cost of a solar panel system varies according to:
Though you should expect to pay a little more for the best solar panels, opting for more efficient panels that won’t degrade easily means you will break even sooner than with cheaper, less efficient or durable panels.
Generally, solar panels come with 2 types of warranties or guarantees: one for product, and one for performance. Below, we explain what each one covers.
A solar panel’s product warranty relates to its durability and quality. This is a critical factor in our evaluations, as it highlights the manufacturer’s confidence in its product and gives the homeowner a sense of security.
Solar panels naturally degrade over time, meaning they gradually lose efficiency. Typically, there is a 1 to 2 per cent efficiency loss during the first year of use, followed by an annual degradation rate of about 0.2 to 0.7 per cent. A performance warranty guarantees that the panels will perform at a certain level after several years of use. The longer the performance warranty, the more durable the panel should be.
As with any purchase, make sure to check the reputation of any company you’re considering. In our research, we combed through several product and company reviews and have only included brands that are known for their reliable products and sound customer service. We then surveyed over 2,000 solar panel owners to gauge how they feel about their panel provider.

| SunPower | 90% | 92% | 92% | 91% |
As solar panels are a green, renewable energy source, it makes sense to research manufacturers’ environmental policies and ethics. Not all companies use recycled materials in their production process, though most solar brands have announced initiatives to reduce their carbon footprint during production. Ideally, look out for companies that don’t use lead or fluoride in their solar panel production.
Once you’ve figured out the best solar panels for your needs, you’ll need to think about how to source them and what’s involved in the installation process. We’ve broken down this key information below.
With thousands of solar panel providers nationwide, it can be hard to decide on the best one for you. To help you choose, we’ve reviewed several of the best solar panel installers in the UK.
For each of the companies, we’ve considered factors such as cost, reliability, certifications and accreditations (always choose an installer with Microgeneration Certification Scheme accreditation) and the installation warranty offered. Although you can install solar panels yourself, we wouldn’t recommend it, both because of the technical skills required, but also because a professional installation is usually required if you want to take advantage of the SEG scheme.

Discover how much the best solar panels for your home could cost by answering a few quick questions.
After carefully reviewing solar panels from dozens of providers, our solar experts chose Project Solar as the brand with the best solar panels, specifically the Project Solar Evolution Max 500W. It has a high efficiency rate of 25.5 per cent, a high output of 500W and lifetime warranties.
In the UK, it’s best to choose solar panels with decent weather resistance like N-type panels to limit potential damage caused by wind, rain or snow. Monocrystalline panels are also preferable as they are more efficient than polycrystalline ones, including in overcast weather.
The field of solar technology is continuously evolving, and newer, more efficient panels are constantly coming to market. Currently, the best type of solar panel you can buy are monocrystalline N-type panels, as they are the most efficient and durable.
Solar panels may add value to your home if you look to rent or sell it in the future, as they may attract sustainably-minded people or those looking to save on their energy bills. That said, it’s not worth buying solar panels just for that reason.
The quality of the panels does vary across brands. Most panels have different degradation rates, power outputs, efficiencies, temperature coefficients and, of course, costs. These factors will affect your system’s lifespan, so it’s important to thoroughly research brands and read up on solar panel reviews.
