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 largest one is the size of the system your household needs, and other factors include the equipment you choose, financing options and the solar company you choose.
Solar Equipment
System size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of installing solar panels. Because of that, it’s a priority to accurately gauge the size of the solar energy system needed for your home by figuring out your typical energy use.Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer higher efficiency. In a city like Walpole, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or you don’t have a lot of 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
Most solar installers in Walpole provide solar loans, which reduce the initial cost of installing solar.When figuring out your overall cost, you should also calculate the interest you’ll pay if you decide on a solar loan. Also, paying a higher down payment can reduce the total interest paid over time.
Solar Panel Installation Company
A final factor to keep in mind when trying to estimate the cost of solar for your home or business in Walpole is the company you choose to install your PV system. As with choosing a company to build a deck or pool, for instance, there’s no shortage of solar installers that provide a range of services for different budgets.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 specific equipment options like Tesla Powerwall batteries or additional services like electric car charger installation, they might be cheaper overall.

EcoWatch's Walpole, MA 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 $20,300 for a 5-kW system and $40,600 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 higher-than-average energy consumption. Conversely, you can spend less if you go with a smaller solar panel system or cheaper solar panels.
Should I lease or buy solar panels in Walpole?
Leasing solar panels can be an appealing choice, because it commonly comes with low or $0 upfront payments. The downside is that you won’t be able to save as much. If you lease, you don’t own the system, so you can’t claim any tax rebates and credits and your home value won’t increase. Buying solar panels is a better option if you want to get the most savings.
Do solar panels increase the value of your home?
Buying or financing solar panels for your home can increase the value of your property by about 4%, according to research done by Zillow. The average home value in Walpole is currently $696,145, which means you can expect a value of about $28,542 more than houses without a solar system. The exact figures will vary, but most experts agree that installing solar panels in Walpole is a fruitful investment.
How many solar panels should I get to power my home?
To figure out how many solar panels you need, you need to know how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
