Factors that Affect Solar Panel Costs in London

While the average cost of solar panels in London is $13,368, your final cost may be higher or lower than that. There are several factors that can have a significant impact on the cost of a solar panel installation. Below are some of the more important things to keep in mind.

Solar Equipment

One of the most important factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more energy your household consumes, the larger your system will likely need to be. You can expect to pay about $2,560 per kilowatt in London. Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like London, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or limited 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

Many homeowners find the average cost of solar in London to be prohibitively expensive, even if the investment pays off over time. Thankfully, almost every solar installer in the area provides financing options. Solar loans substantially decrease upfront costs in most cases, but they also lead to a higher cost over time due to interest. You'll have to consider the long-term cost of financing options, 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 original cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs considerably.

Solar Panel Installation Company

A final consideration when trying to figure out the cost of solar for your home or business in London is the company you get to install your PV system. As with choosing a company to renovate your kitchen, for example, there's no shortage of solar installers that offer a range of services at different costs. Larger national companies generally have lower costs, but some local companies undercut them by offering sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or extra services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

The company that does your solar panel 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 challenge, we have some tips to help you, such as:

  • Solar Panel Brands: The brand of solar panel you need to get plays a part in which installer you should opt for, since different companies have access to different panels.
  • Warranty: Many companies offer different types of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
  • Reputation: Your solar installer should have a sound reputation as a company and have demonstrated expertise in the field. A couple of ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from previous customers.
  • Contract: When reading over your solar installer's contract, ask questions about any terms you're not sure of and be sure you understand what happens in scenarios such as a system component breaking or if the company goes out of business.

EcoWatch's London, OH Solar Cost FAQs

What is the average cost of installing solar panels in London?

The average cost of solar panels in London is about $12,800 for a 5-kW system and $25,600 for a 10-kW system before the ITC, but the actual cost will depend on certain factors like the kind of solar panels you want, what size system you need and how much energy you consume.

What other factors should I consider aside from cost when buying solar panels?

The upfront cost is a crucial factor to consider, but whether it's the most important for you depends on your goals for going solar. In places where rooftop space is limited, efficiency can trump the cost. Other factors that are important to think about are the quality and durability of your solar panels.

Can you sell solar power back to the grid in London?

Most states have net metering programs of some kind. Through these, you can either receive compensation for the extra power your system generates or or receive credits to put toward future energy bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.

How often do you have to replace solar panels?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is their energy production will have decreased significantly after that point. You can replace them once you've had them for that long or you can keep using them at a lower efficiency.
