Methodology: How We Ranked the Best Solar Companies in London

EcoWatch's solar experts analyzed each solar company in London based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in London


Below are some the criteria we examined specifically for Kentucky solar companies

  • Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
  • Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
  • Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
  • Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
  • Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
  • Availability (10%): The bigger the service area, the higher the company will score.
  • Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
  • Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.

The Cost and Benefits of Solar in London

Although solar panels can help save you a decent chunk of change on utility bills over time, it’s important to take into consideration the upfront costs.A few main factors that determine the cost of installing solar panels on your home and how much money you could save over time are:

  • Incentives: One thing that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that’s equal to a percentage of the project cost. You can also save money on your utility bills, which can generate an average of $16,000 of savings over 20 years.
  • How much sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar panel system won’t be able to produce as much energy, which will leave you with lower savings on electric bills than a roof that gets lots of sunlight.
  • Typical energy usage: The more energy your household consumes on average and the larger your current energy bills are, the more likely you'll benefit from switching to solar.
  • The type of solar panels you have the money for: This hinges on your income and budget.

Because of solar panels now being cheaper than ever as well as various solar incentives, they are a cost-effective investment for many homeowners.

What are the best and worst things about solar power?

A few of the biggest pros are that it lowers your power bills, it’s a sustainable source of energy, and it can give you a decent return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, they cost a lot upfront and solar panels aren’t always aesthetically pleasing.

How long does it take for solar to pay for itself?

The average payback period for solar panel installation is about 15.2 years, but the exact period varies depending on local electricity costs, incentives and net metering programs.

What is the best type of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can’t, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and how much energy generation you want.
