Factors that Affect Solar Panel Costs in Brookline
The cost of installing a solar system in Brookline can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The biggest one is your system size, and other factors include the equipment you choose, financing options and the solar installer you choose.
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 energy your household uses, the larger your system will likely need to be. You can expect to spend about $4,220 per kilowatt in Brookline.Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Brookline, where sunlight isn’t as abundant, efficiency can quickly pay off. Also, 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
For some homeowners, paying for solar panels out of pocket can be a challenge. Solar loans are available from most installers in Brookline, which can bring down, or in some cases eliminate, your upfront costs to make solar more accessible.You’ll have to consider the long-term cost of financing options, including the amount of interest you’ll pay over the length of the loan. If you’re only able to 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 APR could reduce your costs remarkably.
Solar Panel Installation Company
A final consideration when trying to estimate the cost of solar for your home or business in Brookline is the company you hire to install your PV system. As with choosing a company to install new cabinets, for instance, there are plenty of solar installers that provide a range of services for different budgets.You may notice national solar installers that have lower prices due to their bigger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or promotions to compete with those major players.
