Factors that Affect Solar Panel Costs in Londonderry
The cost of installing a solar system in Londonderry can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The most significant one is the size of the system your home needs, and other factors include equipment choices, financing options and the solar installer you choose.
Solar Equipment Size
When it comes to estimating the cost of a solar energy system in Londonderry, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home's energy consumption, which you can determine by looking at past energy bills. Your total cost can increase by about $2,910 for each additional kilowatt you need. Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer better efficiency. In a city like Londonderry, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, 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
Many homeowners find the average cost of solar in Londonderry to be too costly, even if the investment pays off over time. Thankfully, nearly every solar company in the area provides financing options. Solar loans drastically decrease upfront costs in most cases, but they also lead to paying more over time because of interest. However, the interest on solar loans also adds to your all-in costs, so it's vital to consider that as well. You can always bring down the total you pay in interest and in some cases even your APR by making a larger down payment.
Solar Panel Installation Company
The solar installation company you choose will play a role in your total cost to adopt solar power. Different companies will charge different amounts for the equipment and labor. Larger national companies typically have lower costs, but some local companies undercut them by offering sales and discounts. While the smaller companies might not have 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
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 difficult, we have some tips to help you, such as:
- Installation Process: One of the most important things to understand when adopting solar energy is the installation process itself. Be sure to align on any details you need to know with your solar installer, such as what permits you should secure and what the project timeline is.
- Contract: Read the contract terms carefully to make sure you understand the total cost, project timeline rebates and warranties.
- Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and how much efficiency they need. Even though there are many options for which type of solar panel you can get, not every company will have the exact one you may want or need, so be sure to peruse their list of options before deciding.
- Reputation: Solar installers that have great reviews from their customers and that have been operating for many years most likely offer high-quality solar panel installation and expertise.
