Factors that Affect Solar Panel Costs in Newton
Cost is usually one of the most important factors for homeowners who are considering investing in solar. There are a few primary factors that determine your overall cost in Newton: solar equipment and system size, financing options and the solar installation company you choose. We’ll discuss each of these briefly below.
Solar Equipment
When it comes to estimating the price of a solar system in Newton, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home’s energy usage, which you can gauge by looking at past power bills. Your total cost can increase by about $4,060 for each additional kilowatt you need.The brand and type of equipment you want for your solar system can increase or decrease the price quite significantly. If you prefer a 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 more savings over time. Also, if you want extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
For some homeowners, paying for solar out of pocket can be challenging. Solar loans are provided by most installers in Newton, which can bring down, or in some cases eliminate, your upfront costs to make solar more affordable.Although solar loans make adopting solar energy more accessible for Newton homeowners, they can also add to the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you make a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
A final factor to consider when trying to estimate the cost of solar for your home or business in Newton is the company you get to install your solar panel system. As with choosing a company to build a deck or pool, for instance, there’s no shortage of solar installers that provide a range of services at different price points.Larger national companies generally have lower costs, but some local companies keep up with them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or additional services like electric vehicle charger installation, they might be cheaper overall.
