Factors that Affect Solar Panel Costs in Brentwood
There are many criteria that can affect your solar system installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.
Solar Equipment
One of the most significant factors to consider when it comes to the cost of going solar 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 about $2,910 per kilowatt in Brentwood. The brand and kind of equipment you want 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 come at a higher price than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have limited roof space 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. Also, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
For some homeowners, paying for a solar system out of pocket can be challenging. Solar loans are available from most installers in Brentwood, which can reduce, or in some cases completely eliminate, your upfront costs to make solar more affordable. However, the interest on solar loans also increases your overall costs, so it's crucial to consider that as well. You can always reduce the total you pay in interest and in some cases even your APR by putting more money down.
Solar Panel Installation Company
The last key cost factor you should take into consideration is the installer you choose. Given the booming popularity of clean energy solutions in Brentwood, you'll have lots of options to choose from, but each comes at various price points for labor and equipment. 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 add-on services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels
Since the type of solar panels and the company you choose has an impact on your costs and your system's durability and efficiency, it's important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:
- Warranty: Companies typically offer different kinds of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
- Contract: Before you sign a contract with a solar company, make sure you read it through completely so you understand the terms. Also, ask questions if you aren't sure about some of the terms, such as what to do if a part breaks or malfunctions and if there are any guarantees about energy production.
- Solar Panel Brands: Different companies offer various brands and types of panels. If you want a specific brand, make sure the solar panel installer you're considering has it.
- Reputation: Make sure your solar installer has a good reputation by verifying it has certifications and licenses, checking how long it's been in business and reading reviews by past customers and solar experts like the EcoWatch team.

EcoWatch's Brentwood, NH Solar Cost FAQs
How much does it cost to install 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 real cost will depend on certain factors like the kind 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?
Cost is without a doubt one of the most important things to bear in mind when buying solar panels, but other important factors include efficiency, durability, and quality.
Is making the switch to solar worth it?
Solar panels can be a great investment for most homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your energy bills are already pretty low, solar panels might not be for you.
How often do you have to replace solar panels?
Although 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 choose to replace them after having them for that long or you can continue to use them at a lower efficiency.
