Factors that Affect Solar Panel Costs in Wellesley

For many Wellesley homeowners, the decision to install solar panels rests on cost. However, the range of solar installation costs can be quite wide in Wellesley, 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 important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $2,940. The solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. On the other hand, higher efficiency could save you more over time on your electric bills. In addition, add-on products, such as solar batteries, can bump up your total well above the Wellesley average.

Solar Financing Terms

Most solar companies in Wellesley have solar loans, which reduce your upfront costs of installing a solar system. While solar loans make switching to solar energy more accessible for Wellesley homeowners, they can also raise the total you pay for your system, depending on your interest rate. If you make a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

Lastly, the company you hire to install your solar panel system can impact your pricing. Wellesley's solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies typically have lower costs, but some local companies keep up with them by promoting 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.

How to Save on Solar Panels

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

  • Warranty: If you're concerned about the durability of your solar system, verifying that your installer offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Contract: Review the contract terms thoroughly to make sure you understand how much it will cost, project completion timeline incentives and warranties.
  • Solar Panel Brands: The model of solar panel you need to install plays a part in which installer you should choose, since different companies offer different panels.
  • Reputation: Well-established companies likely have a solid reputation. This is important because it ensures that it will not only see your solar project through, but will also provide adequate aftercare and customer support, such as part repairs and replacements.

EcoWatch's Wellesley, MA Solar Cost FAQs

How much does it cost to install solar panels in Wellesley?

This is a difficult question to answer precisely, because the cost depends on a variety of factors. Broadly speaking, it costs about $14,700 for a 5-kW system and $29,400 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 higher-than-average energy usage. On the flip side, you can spend less if you choose a smaller solar panel system or cheaper solar panels.

Is it better to lease or buy solar panels in Wellesley?

Leasing solar panels can be an option if you are unable to pay upfront or secure a solar loan, but since you don't own the system, you can't take advantage of many solar incentives. Also your home value won't increase, so you'll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most bang for your buck from going solar.

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

Solar panels can potentially eliminate your electricity bills depending on your location and how much sunlight your home gets. Even if it doesn't get rid of them completely, you can save a lot of money on your bills, about $1,142.75 per year.

How many solar panels do I need to power my home?

The exact number of solar panels you need depends on your household energy consumption and the average daily sunlight your roof gets. You can look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to get between 20 and 35 panels to account for their typical energy usage.
