Factors that Affect Solar Panel Costs in Walpole
For many Walpole homeowners, the decision to install a solar energy system depends on cost. However, the range of solar installation costs can be quite wide in Walpole, with typical prices between $20,000 to $40,000. There are several factors that significantly influence the price you'll pay, which we'll go over below.
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, you can expect your total to increase by about $2,910. There are a lot of different solar panel brands and the one you pick also affects the cost. Typically, the brands that are more efficient tend to also cost more. Additionally, the type of equipment you want 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
Many homeowners find the average cost of solar in Walpole to be prohibitively costly, even if the investment pays off over time. Fortunately, almost every solar installer in the area provides access to financing options. Solar loans remarkably decrease upfront costs for most homeowners, but they also result in higher prices over time due to interest. It's wise to include the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it'll take to pay back the loan.
Solar Panel Installation Company
The solar panel installation company you pick will play a role in your total cost to make the switch to solar power. Different companies will bill different amounts for the equipment and labor. Larger national companies usually have lower costs, but some local companies compete with them by offering sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or extra services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels
There are a large number of companies to choose from in Walpole, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be challenging, so here are some tips to help you decide:
- Warranty: If you care about the endurance of your solar panels, checking if your company offers a 25-year, all-inclusive warranty can give you some peace of mind.
- Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and how much efficiency they need. While 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.
- Installation Process: Get detailed information from your solar installer about the installation process and what to expect, such as when the site survey will be completed and how long it will take.
- Contract: Even though reading through a contract can take a lot of time, it's important to do it fully so you can make sure you understand how much the equipment and services will cost and the terms of the warranty.

EcoWatch's Walpole, NH Solar Cost FAQs
How much does it cost to install solar panels in Walpole?
This is a difficult question to answer precisely, because the cost depends on a few different 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. It will cost more if you want extra solar equipment or more efficient panels, or if you have above-average energy needs. On the flip side, you can spend less if you go with a smaller solar panel system or cheaper solar panels.
Are solar panels free in Walpole?
Solar panels aren't free in Walpole, but there are some options that can make getting them more feasible, such as leasing solar panels or getting a solar loan. There may also be local programs or incentives that can help lower the cost.
Does Walpole 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 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 higher amount of energy production.
