Best solar panel overall: SunPower Maxeon 6

SunPower

Solar Panel Type Price Range (4kW System) Power Output Size Efficiency Warranty Period
Monocrystalline £6,600 - £7,500 475W Up to 22% 25-40 years

SunPower's Maxeon range is known for its high quality, exceptional power output, and great warranty period. In addition to these impressive features, the Maxeon 6 is also highly durable, having one of the lowest degradation rates compared to other solar panel brands (2.0% in the first year and 0.2% for each year after that). This makes the Maxeon 6 one of the best solar panels in terms of quality and durability. 

Alongside outstanding solar panels, this US-based manufacturer also offers solar batteries that you can pair with your solar system to store energy for later use. Of course, such an addition will incur extra costs, so make sure to check if a SunPower solar battery is feasible for you. 

At the same time, it's important to note that there are also some downsides to the Maxeon 6. The primary disadvantages of this solar panel model are that it's more expensive than other brands and that it's also heavier than other options, so it might not be the best solar panel for some roof types.

Best solar panel in terms of warranty: Project Solar Evolution Titan 445

Project Solar

Solar Panel Type Price Range (4kW System) Power Output Size Efficiency Warranty Period
Monocrystalline £4,500 - £8,000 445W Up to 21.4% Lifetime (99.9 years)

Project Solar is one of the best UK-based solar panel manufacturers today. Their Evolution Titan 445 solar panels are known for their high quality and impressive power output (445W). 

What truly sets this model apart, making it one of the best solar panels in the UK, is its outstanding lifetime warranty. With a 99.9 year warranty, homeowners who opt for Project Solar's Evolution Titan 445 can rest assured that any damage to their solar panels will be covered for years to come. 

In addition to these impressive features, the Evolution Titan 445 also has a sleek finish and produces energy efficiently year-round. However, it also comes with some disadvantages. These solar panels are more expensive than other options and they are also not as lightweight as other models, so make sure that you consult a solar panel installer to determine whether they're the right choice for your home. 

Best solar panel in terms of efficiency: REC Alpha Pure-R

REC

Solar Panel Type Price Range (4kW System) Power Output Size Efficiency Warranty Period
Monocrystalline £5,000 - £7,000 430W 22.3% 20-25 years

For homeowners who prioritise solar panel efficiency, REC Group's Alpha Pure-R is an appealing option. With an outstanding 22.3% efficiency rate, these are some of the most efficient solar panels in the UK today. 

These high quality solar panels also have an excellent power output (430W) and they are known for their durability. That said, some downsides of the REC Alpha Pure-R are that they are more expensive than other brands and they are also not as widely available as other models. So, be sure to weigh the pros and cons of these solar panels before having them installed.

Best solar panel in terms of power: REA Solar Fusion 2

REA Solar

Solar Panel Type Price Range (4kW System) Power Output Size Efficiency Warranty Period
Monocrystalline £5,000 - £8,000 465W 22% 25 years

When it comes to power output, REA Solar Fusion 2 solar panels are nearly unmatched. This is because of the innovative Fusion technology that allows these solar panels to produce more energy while not compromising on their efficiency. With a power output of up to 465W, these solar panels are an excellent option for households with high energy needs. 

However, this model also has some disadvantages. The most notable ones are their high cost, as they are on the higher end of the solar panel cost in the UK, and their shorter warranty period compared to other brands. 

Best solar panel in terms of cost: Sharp NU-AF

Sharp

Solar Panel Type Price Range (4kW System) Power Output Size Efficiency Warranty Period
Monocrystalline £1,900-£2,500 370W 19% 10-25 years

Sharp solar panels are renowned for their quality and durability. When it comes to their NU-AF model, they combine impressive solar technology with affordability. At about £190 per solar panel, Sharp NU-AF solar panels are some of the cheapest solar panels on the market. 

While they are some of the best solar panels for a lower budget, there are also some disadvantages when it comes to Sharp NU-AF solar panels. For instance, they have a higher performance degradation rate of 0.7% per year. As a result, you might notice efficiency loss earlier than you would with other models. 

At the same time, compared to other brands, the warranty period that Sharp offers for this model is quite short, meaning that if you face any issues with your solar panels, you might not be able to benefit from your warranty.

How did we choose the best solar panels in the UK?

When compiling our list of the best solar panels in the UK this year, we considered several factors that we compared across different brands and models. These include:

Best solar panels factors

  1. The reliability of the manufacturer: To ensure that you are investing in high-quality solar panels, you will want to ensure that you are getting them from manufacturers with years of experience with producing reliable solar technology. All the solar panel models on our list are from solar panel manufacturers with a long history of creating high-quality products. 
  2. Efficiency rates: Our list only includes highly-efficient solar panels. Most of them have efficiency rates of 20% or higher, which means that you will be able to enjoy efficient energy production with any of these models. Monocrystalline panels have the highest performance when compared to other commercial solar panels like polycrystalline and thin-film solar panels.
  3. Power output: We considered the power output of the solar panels on our list because it is an important indicator of how many solar panels you will need to satisfy your household's energy needs. By selecting solar panels with a higher power output, you can have fewer solar panels installed on your roof and still enjoy sufficient energy production. In terms of power output, monocrystalline bi-facial panels can generate the highest output for the lowest cost.
  4. Performance degradation: Solar panels inevitably degrade over time. However, the models in our list of best solar panels all have low degradation rates. We considered this factor because it is an indicator of how long your solar panels can continue to generate energy for your home efficiently, helping you avoid mounting energy costs. After 25 years solar panels tend to degrade between 2% to 15% depending on the model.
  5. Warranty period: As with any purchase you make, a warranty is an important part of investing in solar panels. To avoid any huge expenses if your solar panels suffer any damage, you will want to opt for a model that comes with a long warranty period. All the solar panels on our list come with impressive warranties, offering you the peace of mind that your solar system can be covered for years to come. 
  6. Cost: Solar panels are far from cheap. We also factored in costs to make sure that the solar panels on our list have a good price-quality ratio. However, most of the models we have mentioned are still quite expensive. To lessen the financial burden of investing in solar energy, make sure to check whether you are eligible for any solar panel grants available in the UK.
