Factors that Affect Solar Panel Costs in Windham
Cost is typically one of the most important factors for homeowners who want to invest in solar. There are a few key factors that affect your total cost in Windham: solar equipment and system size, financing options and the solar installation company you choose. We'll discuss each of these briefly below.
Solar Equipment
One of the most important factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household uses, the larger your system will likely need to be. You can expect to spend around $2,910 per kilowatt in Windham. Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like Windham, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or limited space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries 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 big investment. That's why many Windham homeowners decide to finance their solar panel systems to make going solar more affordable. While solar loans make adopting solar energy more accessible for Windham homeowners, they can also add to the total you pay for your system, depending on your interest rate. If you make a larger down payment, though, you can avoid paying as much in interest.
Solar Panel Installation Company
A final consideration when trying to estimate the cost of solar for your home or business in Windham is the company you get to install your PV system. Similar to choosing a company to build a deck or pool, for instance, there are plenty of solar installers that provide a range of services at different price points. Additionally, some companies in Windham are more knowledgeable about local solar incentives and can help you take advantage of additional rebates or tax exemptions. Though, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels
There are many solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you find the right company for you, here are some tips to keep in mind:
- Reputation: Long-standing companies likely have a solid reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide quality aftercare and customer support, such as part repairs and replacements.
- Solar Panel Brands: Homeowners will have different preferences for panels based on their locations and energy needs. While 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: Though reading through a contract can be tedious, it's important to do it carefully so you can be sure you understand what services your solar company will provide and the terms of the warranty.
- Warranty: A quality company rises above other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.

EcoWatch's Windham, NH Solar Cost FAQs
How much does it cost to install solar panels in Windham?
This is a tough question to answer precisely, because the cost depends on many factors. Generally 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 extra solar equipment or more efficient panels, or if you have higher-than-average energy consumption. On the flip side, you can spend less if you opt for a smaller solar panel system or less expensive solar panels.
What other factors should I consider aside from cost when buying solar panels?
Cost is without a doubt one of the most important things to keep in mind when buying solar panels, but other important factors include efficiency, durability, and quality.
Can you sell solar power back to the grid in Windham?
The majority of states have net metering programs of some kind. Through these, you can get paid for the extra power your system produces or or receive credits to put toward future electricity 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?
On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger level of energy production.
