  • Efficiency: We selected the best solar panels based on how efficient they are. With most of them having ratings of 20% or higher, they are guaranteed to produce energy for your home efficiently. 
  • Power output: Our list of best solar panels in the UK includes solar panels with a high power output to ensure that the system you choose will easily tend to your household’s energy needs. 
  • Temperature coefficient: This measurement is important in determining how much the efficiency of solar panels will drop when temperatures increase. All the solar panels in our list have a low temperature coefficient, allowing them to remain highly efficient over time. 
  • Performance degradation: While it is inevitable that solar panel performance degrades over time, the 5 best solar panels we have listed are known for their low degradation rates. This means that these solar panels will continue to generate energy for your home efficiently for longer. 
  • Warranty period: The best solar panels on the market and in our list are accompanied by extensive warranty periods to ensure that homeowners can enjoy the benefits of their solar system for longer.
