Factors that Affect Solar Panel Costs in Walpole

Cost is usually one of the most important factors for homeowners considering investing in solar. There are a few key factors that will push your cost above or below the average in Walpole: solar equipment and system size, financing options and the solar installation company you choose. We'll discuss each of these briefly below.

Solar Equipment Size

The size of the solar system you need to offset your energy usage is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by nearly $2,940. The brand and kind of equipment you get for your solar system can increase or decrease the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have a small roof 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. Plus, if you want extra equipment like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

If paying for a solar system out of pocket is too expensive, solar loans are a popular option because they cut back your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years. It's wise to factor 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 off the loan.

Solar Panel Installation Company

The solar company you hire to handle your switch to sustainable energy can have an effect on your total costs. There are about 3 solar panel companies operating in Walpole, and each can charge different amounts for labor and equipment. You may see national solar installers that have lower prices due to their bigger brand name and access to bulk prices, or you might see small, local installation companies offering deals or specials to compete with those larger companies.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you pick the right company for you, here are some tips to keep in mind:

  • Reputation: Make sure your solar installer has a good reputation by verifying it has certifications and licenses, checking how long it's been in business and reading reviews by past customers and solar experts like the EcoWatch team.
  • Solar Panel Brands: Not all solar companies carry the same brands of solar panels, so the brand and type of panel you want can play a significant role in the company you opt for.
  • Warranty: Each company may offer different types of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
  • Contract: When reading over your solar company's contract, ask for clarification about any terms you're not sure of and be sure you understand what happens in scenarios like a system part breaking or the company going out of business.
