Top 5 Solar Panels

  • SunPower Maxeon 6

  • Project Solar Evolution Titan 445

  • Jinko Solar Tiger Neo 72HL4

  • JA Solar JAM72S30

  • Suntech Ultra V Mini

The Best Solar Panels for Efficiency

SunPower Maxeon 6

SunPower Maxeon 6

We’re starting off our list with the SunPower Maxeon 6, which has efficiencies up to 22.8%. The best solar panels from SunPower offer a high output whilst remaining strong enough to handle minor impacts and corrosion. Where most panels are designed to be as strong as their weakest cell, the SunPower Maxeon features cells that work independently, which increases power by about 50%.

The Best Solar Panels for a Lifetime

The second on our list is the Evolution Titan from Project Solar. Their best solar panels are one of the best all rounders on offer today. They are designed with a lifetime warranty and have an impressive 21.4% efficiency rating. Breakages are covered under the 99.9 year warranty, provided they can’t be fixed by their maintenance team. Featuring great performance in low light, you won’t miss out on energy generation either.

The Best Solar Panels for Reliability

Jinko Solar Tiger Neo

Jinko Solar Tiger Neo

Third on the list is the Jinko Solar Tiger Neo. This panel can achieve up to 22.23% efficiency and features Potential Induced Degradation (PID) resistance, which prevents greater efficiency loss over time. Jinko’s best solar panels work well in extreme environmental conditions, which is useful for coastal properties or areas prone to storms. A 25 year warranty helps to put your mind at ease, along with a 30 year warranty on power.

The Best Solar Panels for Power Output

JA Solar JAM72S30

JA Solar JAM72S30

The fourth panel on our list is the JA Solar JAM72S30. Featuring an impressive 550W output, they are resistant to hot spot degradation and weathering. In terms of price and power output, their best solar panels can’t be beaten. On the downside, they are heavier than other types, at 28.6kg, and the product warranty only lasts for 12 years.

The Best Solar Panels for Price

Suntech Ultra V Mini

Suntech Ultra V Mini

From as little as £155, the last solar panel on our list is the Suntech Ultra V Mini. Featuring panels that work well in all conditions, including low light, these present great value for money. Shaded areas are no longer a problem as the silicon wafers from Suntech’s best solar panels are designed to capture as much energy as possible. Also with a 12 year warranty, these panels are up to 20.7% efficient.

UK Energy Generation for Last Year

Last year, the UK generated 30.5GW of energy, which was 101.3% of demand. You can see a breakdown of which fuel types were used most in the interactive graph below.

Solar power, including the best solar panels on residential properties that exported to the grid, only accounted for 4.7% of the total, which is still an impressive 1.26GW. The biggest renewable energy generator was wind.

The Best Solar Panel Manufacturers

Based on the best solar panels in the UK outlined above, the manufacturers ahead of the competition are:

  • SunPower

  • Project Solar UK

  • Jinko Solar

  • JA Solar

  • Suntech

How to Choose the Best Solar Panels for You

Sometimes, it’s not just a case of picking the most efficient panels on the market. There are other considerations to think about that go beyond the price. To find out what the best solar panels for your home are, think of the following key points.

Power Output

Depending on how much energy you will need for your home, you can benefit from more power generation throughout the year with higher power outputs. If you need around 850kWh of electricity a year, the best solar panels for you will be enough for a 1kW system. Any more than this and you’ll be wasting money. It's crucial to understand how many solar panels you'll need.

Likewise, if you have a higher electricity demand, and need 4,500kWh, a 5kW system will cover what you need. Anything less than this and you will struggle to cope. Anything more and you’ll be spending money for the sake of it. The higher the output of a single solar panel, the fewer you’ll need to install, which can help you save. Similarly, fitting the same number of higher wattage panels will give you more power.


Better efficiencies mean more sunlight converted into electricity. Even though degradation is expected as the years go by, you are usually guaranteed to have at least 80% of a panel’s original efficiency after 25 years. The longer they are in use, the less they are able to generate electricity, until a replacement is more worthwhile.

The best solar panels for you could have the highest efficiencies on the market, such as the 25% in JA Solar’s n-type cells. Alternatively, even a reliable 20% efficient panel could work for you, depending on how much energy you need to generate. It will also depend on the weather at any given point to determine how much electricity is produced.

Every quality product should feature a warranty, both for the product and for its performance over the years. One is for the physical structure of the module, against breakages, damage and labour, while the other is for the energy generation after a given time period. The longer these warranties last, the more you can trust the product.

The best solar panels have product and performance warranties that last for at least 25 years. Some manufacturers err on the side of caution and only offer a 12 year warranty, but this doesn’t mean it’s likely to fail after this time. The lifetime warranty (99.9 years) from Project Solar is the most impressive in the market.


It may be the simplest choice to pick the least expensive option available, but if it’s not going to last or will be inefficient within a short time frame, you’ll end up wasting money on replacements. In the same time frame, you could have paid out a little more to get the quality and durability that would suit you better.

While cost is always a factor, the best solar panels for you and your home could be vastly different from the next person’s. While the £350 modules could be of more use, the £170 option could work for you just as well without giving you any issues. If you’re installing 6 panels on your roof, this could save you £1,080 on the unit cost alone, let alone the upfront costs.

Do You Need the Best Solar Panels on the Market?

The best solar panels don’t have to be the most expensive, but superior quality certainly pays off, especially when it comes to solar technology. More intuitive use of materials and manufacturing processes ensures you won’t have to replace your system for a long time, and gives you the energy you need year after year.

There’s never been a better time to make use of the best solar panels in the UK, as innovation is always improving. Some of these cells are being offered at incredibly competitive prices as well, keeping the option of going solar more realistic for hundreds of thousands of homeowners.

If you’re struggling to afford solar panels, you may be able to make use of various solar panel grants that are currently available throughout the UK.
