Factors that Affect Solar Panel Costs in Brentwood

While the average cost of a solar system in Brentwood is $5,809, your final cost may differ. There are many factors that can have a significant impact on the cost of a solar system installation. Below are some of the more important things to consider.

Solar Equipment

When it comes to estimating the price of a solar system in Brentwood, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home's energy consumption, which you can gauge by looking at past energy bills. Your total cost can increase by around $2,730 for each additional kilowatt you need. Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Brentwood, where sunlight is 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 more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in Brentwood to be too expensive, even if the investment pays off over time. Fortunately, nearly every solar company in the area provides access to financing options. Solar loans substantially decrease upfront costs in most cases, but they also lead to higher prices over time because of interest. You'll have to consider the long-term cost of loans, including the amount of 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 more than the principal cost. Making a larger down payment or getting a solar loan with a low interest rate could reduce your costs remarkably.

Solar Panel Installation Company

A final factor to consider when trying to evaluate the cost of solar for your home or business in Brentwood is the company you hire to install your solar system. As with choosing a company to build a deck or pool, for example, there's no shortage of solar installers that provide a range of services for different budgets. The size of the company sometimes plays the most significant role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower prices because they have more resources and better 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 companies.

How to Save on Solar Panels

The solar company you go with will be a major factor in determining not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are some important things you should take into account, including:

  • Solar Panel Brands: Different companies will offer various brands and kinds of panels. If you want a specific brand, make sure the solar panel company you're considering has it.
  • Reputation: Solar panel companies that have great reviews from their customers and that have been in business for many years most likely provide quality solar panel installation and expertise.
  • Warranty: A comprehensive, 25-year warranty can help keep your solar panels running for a long time and save you money on part replacement and repairs.
  • Contract: It's important to read your solar installer's contract fully to understand what services they will provide, what the warranty covers and what expectations you should have about the project timeline.
