Factors that Affect Solar Panel Costs in Walpole

The cost of installing a solar system in Walpole can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The biggest one is the size of the system your home needs, and other factors include the equipment you choose, financing options and the solar company you choose.

Solar Equipment

The size of the solar system you need for your household, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by about $4,220. Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like Walpole, where sunlight isn’t as abundant, efficiency can quickly pay off. Plus, 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

Many homeowners find the average cost of solar in Walpole to be too steep, even if the investment pays off over time. Fortunately, nearly every solar installer in the area offers financing options. Solar loans greatly decrease upfront costs for most homeowners, but they also lead to higher prices over time because of interest.It’s a good idea to factor the interest you’ll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and the amount of time it’ll take to pay off the loan.

Solar Panel Installation Company

The solar installer you go with to handle your switch to green energy can have an effect on your total costs. There are about 3 solar installation companies in Walpole, and each can charge varying amounts for labor and equipment.Companies that only sell high-efficiency and high-priced products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It’s best to do some research and choose a company that has the products, warranties and services you want and also fit into your budget.

How to Save on Solar Panels

The company that does your solar system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Since picking a company can be difficult, we have some tips to help you, such as:

  • Installation Process: Make sure you’re on the same page with the installer regarding how the installation process will go and what needs to be done before your solar panels are installed, such as updating or replacing your electrical system or roof.
  • Reputation: Companies that have been operating for many years 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 adequate aftercare and customer service, such as part repairs and replacements.
  • Warranty: A high-quality company stands out from other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Contract: Before signing a contract with a solar installer, make sure to read it through carefully so you understand the terms. Also, ask questions if you’re unsure about some of the terms, such as what the warranty covers and what services you can expect from them.

EcoWatch's Walpole, NH Solar Cost FAQs

What is the average cost of installing solar panels in Walpole?

This is a difficult question to answer precisely, because the cost depends on a few different factors. Broadly speaking, it costs about $21,100 for a 5-kW system and $42,200 for a 10-kW system after the ITC is applied. You can expect to pay more if you want additional solar equipment or higher quality panels, or if you have above-average energy consumption. On the other hand, you can spend less if you go with a smaller solar panel system or cheaper solar panels.

Is cost the most important thing to think about when buying solar panels?

Cost is a crucial factor to consider, but whether it’s the most important for you depends on your goals for going solar. In places where rooftop space is limited, efficiency can trump the cost. Other factors that are important to keep in mind are the quality and durability of your solar panels.

How much can I save on energy bills after installing solar panels?

Solar panels can potentially eliminate your electricity bills depending on where you’re located and the efficiency of your system. Even if it doesn’t get rid of them completely, you can save a lot of money on your bills, about $1,000.80 per year.

What solar power system size is right for my home?

To figure out what solar panel system size you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average household will need 20 to 35 panels.
