How did we choose the best solar panels?

Our researchers spent 34 hours investigating the solar panel market, first narrowing the huge field down to the top 48 models currently available.

After analysing each panel’s specifications, we determined the nine best solar panels and gave them a rating out of five across each of these key criteria:

  • Power
  • Efficiency
  • Product warranty
  • Performance warranty
  • Heat resistance
  • Eco-friendly credentials
  • Appearance

You can see a further explanation of these factors below the reviews.

So, now that you know the criteria we measured these solar panels against, let’s get into our ratings and recommendations.

SunPower Maxeon 6 AC – best for most homes

SunPower Maxeon 6 AC

The SunPower Maxeon 6 AC has a 40-year product warranty (SunPower)

The SunPower Maxeon 6 AC is the best all-rounder in our test. It excels in the key areas of efficiency and warranty, and also performs well on power, heat resistance and eco-friendliness.

The panel’s efficiency rating puts it in the top 10% of all those we tested, enabling it to make the most of limited sunlight. It won’t let you down, either: SunPower promises it’ll produce at least 88.25% of its original output after 40 years.

When this panel does eventually reach the end of its useful life, SunPower even promises to recycle it.

Pros

  • Its 40 year product warranty is one of the best available
  • At 22.8%, it has one of the best efficiency rates on the market

Cons

  • With a 92% performance warranty after 25 years, it is durable and reliable
  • It is quite heavy, and you should take that into account before you buy it

AIKO N-Type ABC White Hole Series (72 Cells) – best for efficiency

AIKO N-Type ABC White Hole Series (72 Cells)

The ABC White Hole Series has a landmark 24% efficiency rating  (AIKO)

The 24% efficiency rate of AIKO’s powerful 72-cell N-Type ABC White Hole Series panel is a new landmark best for domestic solar panels, which struggled to get above 20% a few years ago. This makes the AIKO panel a great choice if your roof space is limited, or you don’t get much sunlight.

AIKO also offers an excellent performance warranty, promising at least 88.85% of original output after 30 years. The product warranty lets the side down, though.

Pros

  • Its 24% efficiency rate is the best on the market
  • It has one of the best performance warranties at 88.85%
  • Its peak power rating of 620W is one of the best available

Cons

  • It is one of the biggest and heaviest panels we tested
  • Its 15-year product warranty is at the low end

Seraphim SRP-670-BMC-BG – best for large households

Seraphim SRP-670-BMC-BG

This panel’s peak power production is 91% more than the standard (Seraphim)

The Seraphim SRP-670-BMC-BG’s peak power rating is almost double the industry standard of 350W per panel, and at least 100W more than most of the panels we considered for testing.

Such a mighty power output won’t be necessary for all homes, but could be ideal if you have a large household with big energy needs. Just make sure your roof is up to supporting panels that weigh 38.5 kg and measure 3.1 square metres each.

Pros

  • At 670W, it has fantastic peak power production
  • Its efficiency rating of 21.57% is better than average
  • Seraphim has great eco-friendly credentials and participates in the UN Global Compact goal to reach zero carbon 

Cons

  • The product warranty is a mere 15 years
  • The performance warranty of 84.95% after 30 years could be better
  • This huge, heavy panel weighs 38.5kg

Project Solar Evo Super Max 455 – best warranty

Project Solar Evo Super Max 455

This panel’s lifetime warranty is industry-leading (Project Solar)

The average product warranty for a solar panel is 25 years, and some stretch to 40 – but Project Solar outdoes them all with a lifetime warranty for its Evo Super Max 455. That’s the kind of confidence you want from a manufacturer.

This panel’s efficiency and power are both near the top end of our tests, too, so you can be sure you’ll get an above-average electricity output. 

Where the Evo Super Max 455 falls down is with its performance warranty, and its lack of eco-friendly innovations – other than the fact that it’s a solar panel!

Pros

  • Lifetime product warranty is unbeatable
  • Its peak power production of 455W is above average
  • Efficiency is also at the top end of the market, at 21.1%

Cons

  • No particular eco-friendly credentials
  • Heat resistance could be better
  • The panel is bigger and heavier than average

SunPower Maxeon 3 – best for reliable performance

SunPower Maxeon 3

This panel will function at 92% after 25 years (SunPower)

SunPower promises that the highly efficient Maxeon 3 will remain productive for decades on end. Thanks to its market-leading performance warranty, you’re guaranteed 92% of original output after 25 years, and 88.25% after 40 years.

With some manufacturers in our test reluctant to promise much more than 80% of output after 25 years, SunPower’s confidence in its recycled panels is reassuring.

Pros

  • The best performance warranty in our tests
  • Great product warranty suggests these panels are durable as well as reliable
  • High efficiency rating of 22.7%, near the top of the range

Cons

  • The panel is small but relatively heavy

Q Cells Q.Peak DUO BLK ML-G9 – best for warm locations

Q Cells Q.Peak DUO BLK ML-G9

Losing only -0.25% for every degree above 25°C is fantastic (Q Cells)

Q Cells’ panel is unusually good at coping in the heat. The panel loses just 0.25% of its efficiency with every degree over 25°C, compared with 0.34% or more by nearly 80% of the panels in our test.

With heatwaves getting more common, it will become more and more important to invest in panels that don’t flag as the mercury rises – and continue to work well for years. Sadly, Q Cells’ product warranty of just 12 years is well below average.

Pros

  • Unbeatable resistance to heat
  • One of the smallest and lightest panels on the market, at under 20kg

Cons

  • Poor product warranty of 12 years
  • No eco-friendly credentials

Panasonic HIT N340 – best for delicate roofs

Panasonic HIT N340

The HIT N340 is lighter and smaller than the average panel (Panasonic)

Panasonic’s HIT N340 weighs in at well below the 22.4 kg industry average, and takes up a modest 1.7 square metres of space, compared with the usual 2 metres. The panel is less powerful than its heavier rivals, but its light weight makes it a wise choice if your roof is fragile or unusually shaped.

The HIT N340’s heat resistance and warranties are also excellent, as are Panasonic’s eco credentials.

Pros

  • The lightest panel on the market
  • Excellent eco-friendly credentials, including net zero by 2030
  • Top-quality heat resistance

Cons

  • Below-average power
  • 20.3% efficiency rating is at the low end in our tests

Panasonic EverVolt EVPV410H – most eco-friendly

Panasonic EverVolt EVPV410H

Panasonic has pledged to reach net-zero by 2030 (Panasonic)

Panasonic isn’t content to put its name to solar panels and call itself green. The brand has a detailed plan to reach net-zero emissions by 2030, with steps including investing in hydrogen and creating net-zero factories.

The EverVolt Series Module is a solid all-rounder, scoring high in our tests for efficiency, heat resistance and light weight, plus an excellent performance warranty.

Pros

  • Excellent eco-friendly credentials, including net zero by 2030
  • Great efficiency rating of 22.2%
  • Superb performance warranty

Cons

  • Middling power rating of 410W

LONGi Hi-MO X6 Explorer 435W – best looking

Longi Himo X6 Explorer

LONGi’s sleek black panels will turn heads (LONGi)

Chinese solar giant LONGi has created a solar panel that could make the cover of Vogue, and it’s no slouch when it comes to performance and efficiency.

The sleek black Hi-MO X6 Explorer will add a modern flourish to your home, but because the panels are subtle and relatively small, people may not even notice them at all.

The 435W Hi-MO X6 isn’t the most powerful panel in our rundown, but its 22.3% efficiency rating means it’ll make the most of any sun it gets. Its above-average performance warranty means it’s guaranteed to deliver for decades, too.

Pros

  • Sleek black appearance
  • Works well on dull days, thanks to an excellent 22.3% efficiency rating
  • Good performance warranty promises 88.9% output after 25 years
  • LONGi aims to use green energy for all its operations by 2028

Cons

  • Product warranty is below average at just 15 years
Key solar panel criteria explained

Our researchers spent 34 hours investigating the solar panel market, first narrowing the huge field down to the top 48 models currently available. After analysing each panel’s specifications and ratings, we then determined the nine best solar panels.

Here are the key factors that helped us narrow down our selection:

  1. Power – Measured in watts (W), power refers to a solar panel’s peak energy production in Standard Test Conditions (STC). A 300 W panel would produce 1,500 watt-hours (1.5 kWh) of electricity in five hours. In 2024, the best residential solar panels have power ratings of between 400 W and a hefty 670 W.
  2. Efficiency – Efficiency refers to the percentage of sunlight hitting a solar panel that can be converted into usable electricity.
  3. Product warranty – Solar panel warranties usually range from 10 years all the way up to 40 years – or even a lifetime warranty, if you opt for the Project Solar Evo Super Max 455.
  4. Performance warranty – The performance warranty guarantees that your panel will produce a certain percentage of its original output for a number of years. This is typically 80-90% after 25-30 years. Today’s best panels produce as much as 92% of their original output after 25 years.
  5. Heat resistance –A solar panel’s heat resistance score refers to the percentage decrease in output that occurs with every extra degree above 25°C. Most panels lose between 0.3% and 0.4% per degree above 25°C, but the best entry on our list drops just 0.25%.
  6. Eco-friendly credentials –We looked into companies’ overall green actions. We then ranked these actions based on their impacts on the environment, from the brand trying to reach net-zero to those doing nothing to stop the ongoing climate disaster.
  7. Appearance – Panels are getting darker and sleeker, with the latest premium monocrystalline ones looking like panes of glass.

Another criteria that we didn’t measure for all panels was weight. The typical three-bedroom house needs 10 solar panels to cover its electricity usage, so if your roof is old or delicate, it may not be able to hold the biggest and heaviest panels.

This makes lightweight, efficient panels an important alternative for anyone with a less reliable roof.

How do I know which are the best solar panels for my home?

Our nine best solar panels are all excellent products, but the one that’s right for you depends on your own circumstances. 

Your household energy usage is the most important factor when discussing your panel choices with your installer. If you want to cover the entire energy needs of a large family, the most powerful solar panels may be your best choice – provided your roof is sturdy enough.

If your roof isn’t quite up to the job, or it faces north or west, or it’s overshadowed by trees or tall buildings, then efficiency should be your priority. Solar panels with high efficiency ratings can generate lots of electricity from minimal sunlight, and via a smaller, lighter solar array.

Also consider your future energy needs. Do you plan to buy an electric vehicle (EV) at some point? If so, talk to your installer about investing in a solar panel system that includes an EV-compatible solar battery.

Start your search by comparing quotes and speaking to at least three installers about the panels they can supply, how much they will cost, and what will work best for your home.

To get a rough idea of costs, you can use our solar panel cost calculator.

Price

There’s one big factor we haven’t discussed yet: price.

We’ve not given individual prices for our recommended solar panels, because prices differ depending on where you buy. Unless you’re planning a DIY project, you will almost certainly buy through an installer, and they will add their own installation costs and trade discounts.

Rather than price up individual panels, it’s more useful to cost the whole system, installation included. The cost of your solar panel system will depend on numerous factors, including:

  • The size and shape of your roof
  • Your home’s location in the UK
  • The number and type of panels you need

Your installer will work with you to answer those questions. They will also make recommendations for panels and other solar components based on:

  • Your household’s size and energy needs
  • Your current electricity usage, and how much of the bill you want to cover using solar power
  • Your budget

Can you choose which panels you get?

You’ll have a limited say over which solar panels you get for your home.

Typically, you’ll approach multiple solar installers, who’ll provide you with quotes that all include one of the models they use.

You can (and should) ask about the other panels they buy wholesale, and talk through the models’ respective strengths and weaknesses.

But an installer will almost never buy a set of solar panels just for your property, so your choice will be restricted to the panels used by installers who serve your area.

FAQs

Solar panels are worth it in the UK, by any metric.

With solar panels, you’ll cut your electricity bills, reduce your carbon footprint, and become less reliant on a turbulent power grid.

The average three-bedroom household will break even on solar panels in 14.6 years, leaving you with at least 10 years of pure profit-making – and usually longer.

And the latest research shows that having solar panels on your home when you sell it typically increases its value by 0.9% to 2%.

Around 80% of the world’s solar panels are made in China, according to the International Energy Agency. In fact, six out of the seven largest solar panel manufacturers are Chinese companies.

Solar panels last 25 to 30 years, but that doesn’t mean they stop working entirely after that point. Most high quality solar panels will still retain 80% to 90% of their original output capacity after 25 years.
