Factors that Affect Solar Panel Costs in Londonderry
There are many criteria that can influence your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.
Solar Equipment
System size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of installing solar panels. That's why it's important to accurately gauge the size of the solar energy system needed for your home by figuring out your typical energy use. There are many different solar panel brands and the one you choose also changes the cost. Usually, the brands that have better efficiency tend to also cost more. Additionally, the type of equipment you want to install can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Many homeowners find the average cost of solar in Londonderry to be prohibitively steep, even if the investment pays off over time. Thankfully, almost every solar installer in the area offers financing options. Solar loans greatly decrease upfront costs in most cases, but they also result in paying more over time due to interest. However, the interest on solar loans also adds to your overall costs, so it's crucial to include that in your estimate as well. You can always bring down the total you pay in interest and possibly even your APR by putting more money down.
Solar Panel Installation Company
The solar installer you hire to handle your switch to green energy can have an effect on your total costs. There are about 3 solar panel companies in Londonderry, and each can charge different amounts for labor and equipment. Larger national companies typically have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or additional services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels
Since the brand of solar panels and the installation company you choose has an impact on your costs and your system's efficiency, production, and durability, it's important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:
- Solar Panel Brands: Each solar panel brand and model has varying levels of quality, longevity and energy efficiency. They will come at different prices as well. The company you choose impacts which solar panel brands you have access to.
- Reputation: Your solar installer should have a good reputation as a company and have proven expertise in the field. A couple of ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has satisfied reviews from past customers.
- Contract: Even though reading through a contract can take a lot of time, it's important to do it thoroughly so you can make sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.
- Installation Process: Homeowners should make sure they know how exactly the installation process will be carried out, as well as important factors like the completion timeline.
