Factors that Affect Solar Panel Costs in Derry
Though the average cost of a solar system in Derry is $9,818, your final cost may be above or below the average. There are quite a few factors that can have a significant impact on the cost of a solar panel installation. Below are some of the more crucial things to consider.
Solar Equipment
When it comes to estimating the price of solar panels in Derry, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are primarily 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. There are several different solar panel brands and the one you choose also affects the cost. In general, the brands that have better efficiency tend to also be more expensive. Plus, the type of equipment you're looking 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
Most solar companies in Derry provide solar loans, which reduce the initial cost of installing a solar system. When figuring out your overall cost, you should also calculate the interest you'll pay if you decide on a solar loan. Also, paying a higher down payment can reduce the total interest paid over time.
Solar Panel Installation Company
The solar installer you choose to handle your switch to clean energy can play a role in your total costs. There are about 3 solar installation companies operating in Derry, and each can charge different amounts for labor and equipment. Some companies only sell high-efficiency and high-priced products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It's best to do some research and find a company that provides the products, warranties and services you're looking for and also fit into your budget.

How to Save on Solar Panels
There are a lot of companies to choose from in Derry, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be tough, so here are some tips to help you decide:
- 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.
- 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 brand of solar panel you can get, not every company will have the exact one you may want or need, so make sure you ask for their list of options before making your decision.
- Contract: When reading over your solar company's contract, ask questions about any terms you're not sure of and make sure you understand what happens in scenarios such as a system part breaking or if the company goes out of business.
- Reputation: Your solar installer should have a good reputation as a company and have verifiable expertise in the field. Two 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 good reviews from past customers.

Broadly speaking, it costs about $14,550 for a 5-kW system and $29,100 for a 10-kW system after the ITC is applied. You can expect to pay more if you want additional solar equipment or more efficient panels, or if you have higher-than-average energy consumption.
