Factors that Affect Solar Panel Costs in Londonderry
Although the average cost of a solar system in Londonderry is $16,690, your actual cost may be higher or lower than that. There are quite a few factors that can have a major impact on the cost of a solar system installation. Below are some of the more crucial things to keep in mind.
Solar Equipment
The size of the solar system you need, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $3,550. The brand and kind of equipment you get for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these are often more expensive than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
Solar panels can save you money on utility bills over many years, but they can also be a significant investment. That’s why many Londonderry homeowners choose to finance their solar panel systems to make going solar more affordable.You’ll have to consider the long-term cost of loans, including the amount of 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 above the equipment and labor cost. Making a larger down payment or finding a solar loan with a low interest rate could reduce your costs considerably.
Solar Panel Installation Company
The solar installer you pick will play a role in your total cost to adopt solar power. Different companies will charge different amounts for the equipment and labor.Additionally, some companies in Londonderry know more about local solar incentives and can help you learn about additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels
Since the type of solar panels and the company you choose has an impact on your costs and your system’s durability and efficiency, it’s important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:
- Contract: Before you sign a contract with a solar company, make sure to look it over fully so you understand the terms. Also, ask questions if you aren’t sure about some of the terms, such as what to do if a part breaks or malfunctions and what services you can expect from them.
- Installation Process: Homeowners should understand how exactly the installation process will go, as well as important factors like the project timeline.
- Warranty: Warranties that cover panel repairs and maintenance over a couple decades are the gold standard in the business, and offering that kind of warranty is one mark of a quality company.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to install your solar system. Another way you can research your installer’s reputation is by reading reviews.

EcoWatch's Londonderry, PA Solar Cost FAQs
What is the average cost of installing solar panels in Londonderry?
This is a difficult question to answer precisely, because the cost depends on a few different factors. Broadly speaking, it costs about $17,750 for a 5-kW system and $35,500 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 above-average energy usage. On the flip side, you can spend less if you go with a smaller solar panel system or less efficient solar panels.
Should I lease or buy solar panels in Londonderry?
Leasing solar panels can be an option if you can’t afford to pay upfront or secure a solar loan, but since you don’t own the system, you don’t have access to many solar incentives. Also your home value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most bang for your buck from going solar.
Is making the switch to solar worth it?
Whether or not solar panels are worth it depends on a variety of factors like how much you pay for electricity and the amount of direct sunlight your roof gets.
What solar power system size is right for my home?
To figure out how many solar panels you need, you should find out how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average household will need 20 to 35 panels.
