Factors that Affect Solar Panel Costs in Westborough
Cost is typically one of the most important factors for homeowners who want to invest in solar. There are a few primary factors that affect your total cost in Westborough: solar equipment and system size, financing options and the solar installation company you choose. We’ll go over each of these briefly below.
Solar Equipment
The size of the solar energy system you need, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by nearly $4,060. Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer better efficiency. In a city like Westborough, where sunlight is relatively 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 a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
If paying for solar panels out of pocket is difficult, solar loans are an affordable option because they reduce your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.It’s wise to include the interest you’ll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and the amount of time it’ll take to pay back the loan.
Solar Panel Installation Company
A final consideration when trying to estimate the cost of solar for your home or business in Westborough is the company you get to install your solar system. Similar to choosing a company to renovate your kitchen, for example, you’ll have no shortage of solar installers that provide a range of services for different budgets.Additionally, some companies in Westborough are more knowledgeable about local solar incentives and can help you learn about additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.
