Factors that Affect Solar Panel Costs in Brentwood

While the average cost of a solar system in Brentwood is $14,236, your final cost may differ. There are many factors that can have a significant impact on the cost of a residential solar panel installation. Below are some of the more crucial things to consider.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to a few different factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power production require better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $4,220.The brand and kind of equipment you get for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often have a higher price tag 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 additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Most solar companies in Brentwood provide solar loans, which reduce the initial cost of installing a solar system.You’ll have to consider the long-term cost of financing options, including the total interest you’ll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or finding a solar loan with a low interest rate could reduce your costs considerably.

Solar Panel Installation Company

The last key cost factor you should consider is the installer you choose. Given the booming popularity of green energy solutions in Brentwood, you’ll have many options to choose from, but each comes at varying price points for labor and equipment.Larger national companies generally have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

There are numerous companies available in Brentwood, and some homeowners feel overwhelmed considering their options. Selecting the right company for you can be difficult, so here are some tips to help you decide:

  • Warranty: Each company may offer different types of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a solid reputation and is qualified to get the job done well. Another way you can verify your installer’s reputation is by reading reviews.
  • Contract: Before you sign a contract with a solar company, be sure to read it through 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.
  • Installation Process: Make sure you’re on the same page with the company with regard to how the installation process will go and what needs to be done before your solar panels are installed, such as repairing your electrical system or roof.

EcoWatch's Brentwood, NH Solar Cost FAQs

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

This is a hard question to answer exactly, because the cost depends on a variety of factors. Generally speaking, it costs about $21,100 for a 5-kW system and $42,200 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 above-average energy usage. On the flip side, you can spend less if you opt for a smaller solar panel system or cheaper solar panels.

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

Leasing solar panels can be an attractive choice, because it often 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 maximize your savings.

Do solar panels increase your home value?

Solar panels can increase your property’s value significantly as long as you buy or finance your panels and don’t choose a solar lease or power purchase agreement (PPA). According to research done by Zillow, the average home value increases by about 4.1% after installing a solar system."

What solar power system size is right for my home?

To figure out how many solar panels you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
