Factors that Affect Solar Panel Costs in Marlborough

For many Marlborough homeowners, the decision to go solar rests on cost. However, the range of solar installation costs can be quite wide in Marlborough, with typical prices between $20,000 to $40,000. There are a few factors that considerably influence the price you'll pay, which we'll go over below.

Solar Equipment

The size of the solar system you need for your home, 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 $2,800. Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like Marlborough, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Solar panels can save you money on power bills over many years, but they can also be a big investment. That's why many Marlborough homeowners choose to finance their solar panel systems to offset upfront costs. However, the interest on solar loans also increases your all-in costs, so it's important to keep that in mind as well. You can always lower the total you pay in interest and possibly even your APR by making a larger down payment.

Solar Panel Installation Company

Finally, the company you hire to install your solar panel system can influence your pricing. Marlborough's solar companies all have different labor costs and add varying upcharges to equipment. The size of the company sometimes plays the most significant role in the cost. Larger national companies, like SunPro and Sunrun, often have lower prices because of access to greater resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or discount can bring their pricing down to compete with bigger companies.

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. Because picking a company can be a challenge, we have some tips to help you, such as:

  • Contract: Before signing a contract with a solar company, make sure you look it over carefully so you understand the terms. Also, ask questions if you're not sure about some of the terms, such as what the warranty covers and what services you can expect from them.
  • 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 project through, but will also provide quality aftercare and customer support, such as part repairs and replacements.
  • Solar Panel Brands: Different companies offer various brands and types of panels. If you prefer a specific brand, make sure the solar panel installer you're considering has it.
  • Warranty: Warranties that cover replacement parts and repairs over a couple decades are the gold standard in the business, and offering such a warranty is one mark of a good company.

EcoWatch's Marlborough, CT Solar Cost FAQs

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

This is a difficult question to answer precisely, because the cost depends on many factors. Broadly speaking, it costs about $14,000 for a 5-kW system and $28,000 for a 10-kW system after the ITC is applied. You can expect to pay more if you want additional 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 go with a smaller solar panel system or less expensive solar panels.

What other factors should I consider aside from cost when buying solar panels?

Cost is without a doubt one of the most important factors you should consider when buying solar panels, but other important factors include efficiency, durability, and quality.

Is it worth going solar in Marlborough?

Solar panels can be a fruitful investment for most homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your electricity bills are already pretty low, solar panels might not be for you.

What solar power system size is right for my home?

To figure out what solar panel system size you need, you should find out how much energy your home uses 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 house will need 20 to 35 panels.
