When making the switch to solar, many homeowners opt to use a solar company since overseeing your solar installation yourself can be a difficult project.

Factors that Affect Solar Panel Costs in Brentwood

There are many criteria that can determine your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more power your household consumes, the larger your system will likely need to be. You can expect to spend around $2,910 per kilowatt in Brentwood. There are many different solar panel brands and the one you pick also changes the cost. In many cases, the brands that offer higher efficiency tend to also cost more. Additionally, the type of equipment you choose can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Solar panels can save you money on power bills over time, but they can also be a big investment. That's why many Brentwood homeowners opt to finance their solar panel systems to offset upfront costs. While solar loans make going solar more accessible for Brentwood homeowners, they can also raise the total you pay for your system due to interest. If you make a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

The last significant cost factor you should take into consideration is the installer you choose. Given the booming popularity of renewable energy solutions in Brentwood, you'll have plenty of options to choose from, but each comes at varying price points for labor and equipment. The company's size sometimes plays the most considerable role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower prices because of access to greater resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or discount can bring their pricing lower to compete with bigger names.

How to Save on Solar Panels

The solar panel company you opt for will affect not only your total costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are a few important things you should take into account, including:

  • Contract: Review the contract terms carefully to make sure you understand the cost breakdown, project completion timeline incentives and warranties.
  • Solar Panel Brands: Not all solar installers offer the same brands of solar panels, so the brand and type of panel you want can play a big role in the company you go with.
  • Reputation: Your solar installer should have a good reputation as a company and have demonstrated expertise in the field. A couple of ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from past customers.
  • Warranty: If you care about the longevity of your solar panels, verifying that your installer offers a 25-year, all-inclusive warranty can help put you at ease.

EcoWatch's Brentwood, NH Solar Cost FAQs

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

The average cost of solar panels in Brentwood is about $14,550 for a 5-kW system and $29,100 for a 10-kW system before the ITC, but the actual cost will depend on things such as the model of solar panels you want, what size system you need and how much energy you use.

Is cost the most important consideration when buying solar panels?

The initial cost is a crucial factor to consider, but whether it's the most important for you depends on your goals for going solar. In cities where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to consider are the quality and durability of your solar panels.

Can solar panels significantly reduce my power bills?

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 $984.23 per year.

How often do you have to replace solar panels?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is how much energy they produce will have decreased significantly after that point. You can opt to replace them after having them for that long or you can keep using them at a lower efficiency.
