Factors that Affect Solar Panel Costs in London

There are many criteria that can determine your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. For that reason, it’s important to accurately assess the size of the solar energy system needed for your home by figuring out your average energy use.The brand and type of equipment you get for your solar system can raise or lower the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Most solar companies in London have solar loans, which reduce the initial cost of installing solar.When estimating your overall cost, you should also calculate the interest you’ll pay if you choose to go with a solar loan. Also, paying more upfront can reduce the total interest paid over time.

Solar Panel Installation Company

The solar company you hire to handle your switch to solar energy can play a part in your total costs. There are about 3 solar installation companies in London, and each can charge varying amounts for labor and equipment.You may see national solar installers that have lower prices because of their larger brand name and access to bulk equipment pricing, or you might see small, local installation companies offering deals or specials to compete with those larger companies.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you decide on the right company for you, here are some tips to keep in mind:

  • Contract: Even though reading through a contract can be tedious, it’s important to do it thoroughly so you can be sure you understand what services your solar company will provide and the terms of the warranty.
  • Warranty: A quality company rises above other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Installation Process: One of the most important things to understand when going solar is the installation process itself. Be sure to clarify any details you should know with your solar installer, such as what permits you should acquire and what the project timeline is.
  • Solar Panel Brands: Not all solar companies carry the same brands of solar panels, so the brand and type of panel you want can play a large role in the company you opt for.
