Currently, the national average cost of solar panels is $2.66 per watt. However, in London, the typical cost of a solar system is $2 per watt.

Factors that Affect Solar Panel Costs in London

While the average cost of a solar system in London is $15,741, your actual cost may be higher or lower than that. There are many factors that can have a significant impact on the cost of a solar system installation. Below are some of the more crucial things to consider.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. For that reason, it's crucial to accurately gauge the size of the solar energy system needed for your home by figuring out your energy needs. Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like London, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

If paying for a solar system out of pocket is out of reach, solar loans are an affordable option because they lower your upfront costs and allow you to pay for your system over five to seven years on average. You'll have to consider the long-term cost of loans, including the total interest you'll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the principal cost. Making a larger down payment or securing a solar loan with a low APR could reduce your costs significantly.

Solar Panel Installation Company

Finally, the company you choose to install your solar panel system can affect how much it costs. London's solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in London are more knowledgeable about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

The company that does your solar system installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Because selecting a company can be a tough decision, we have some tips to help you, such as:

  • Solar Panel Brands: Not all solar installers carry the same brands of solar panels, so the brand and type of panel you want can play a considerable role in the company you opt for.
  • Contract: It's important to look over your solar installer's contract carefully to understand what services they will provide, what the warranty covers and what you can expect about the project timeline.
  • Installation Process: When going solar, it's necessary to keep an open line of communication with your solar panel installer. Make sure you understand how the installation process will go and the completion timeline.
  • Reputation: Solar system installers that have great reviews from their customers and that have been operating for many years most likely provide quality solar panel installation and expertise.
