Factors that Affect Solar Panel Costs in Stonington
The cost of installing a solar system in Stonington can vary by more than $10,000 from home to home. Your actual cost is dependent 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 important factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more power your household uses, the larger your system will likely need to be. You can expect to pay around $3,750 per kilowatt in Stonington.The brand and kind of equipment you get for your solar system can raise or lower 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 can expect a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
Most solar companies in Stonington provide solar loans, which reduce the initial cost of installing a solar system.When considering your overall cost, you should also calculate the interest you’ll pay if you opt for a solar loan. Also, paying a higher down payment can reduce the total interest paid over time.
Solar Panel Installation Company
The last major cost factor you should consider is the installer you choose. Given the booming popularity of sustainable energy solutions in Stonington, you’ll have plenty of options to choose from, but each comes at various price points for labor and equipment.Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and choose a company that offers the products, warranties and services you want and also fit into your budget.
