Factors that Affect Solar Panel Costs in Exeter
There are a number of 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 does the installation.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. For that reason, it’s important to accurately ascertain the size of the solar energy system needed for your home by figuring out your typical energy use.The brand and kind of equipment you want for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often have a higher price tag 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 greater savings over time. Also, if you want additional equipment like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
Many homeowners find the average cost of solar in Exeter to be too steep, even if the investment pays off over time. Thankfully, nearly every solar installer in the area provides financing options. Solar loans substantially decrease upfront costs in most cases, but they also lead to higher prices over time due to interest.Though solar loans make adopting solar energy more accessible for Exeter homeowners, they can also raise the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you make a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
A final consideration when trying to estimate the cost of solar for your home or business in Exeter is the company you get to install your PV system. As with choosing a company to renovate your kitchen, for instance, there’s no shortage of solar installers that provide a range of services at different price points.You may notice 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 promotions to compete with those larger companies.

How to Save on Solar Panels
The company that does your system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Since choosing a company can be a challenge, we have some tips to help you, such as:
- Warranty: Many companies offer different types of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
- Solar Panel Brands: Different companies carry various brands and kinds of panels. If you prefer a specific brand, make sure the solar panel installer you’re considering has it.
- Contract: It’s important to look over your solar installer’s contract carefully to understand what services they will provide, what the warranty covers and what you can expect about the project timeline.
- 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 solid reputation and is qualified to install your solar system. Another way you can check your installer’s reputation is by reading reviews.

EcoWatch's Exeter, NH Solar Cost FAQs
What is the average cost of installing solar panels in Exeter?
The average cost of solar panels in Exeter is about $21,100 for a 5-kW system and $42,200 for a 10-kW system before the ITC, but the actual cost will depend on certain factors such as the kind of solar panels you want, what size system you need and how much energy you use.
Is cost the most important consideration when buying solar panels?
Cost is definitely one of the most important things to keep in mind when buying solar panels, but other important factors include efficiency, durability, and quality.
Does Exeter have a net metering program?
Most states offer net metering programs of some kind. Through these, you can either get paid for the extra power your system generates or or receive credits to put toward future energy bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.
How often do you have to replace solar panels?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is their energy production will have decreased significantly after that point. You can replace them after having them for that long or you can continue to use them at a lower efficiency.
