Factors that Affect Solar Panel Costs in East Sandwich
Even though the average cost of a solar system in East Sandwich is $11,716, your final cost may be above or below the average. There are several factors that can have a significant impact on the cost of a solar system installation. Below are some of the more crucial things to take into consideration.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to a few different factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power generation need better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $4,060.The brand and type of equipment you want for your solar system can increase or decrease the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often have a higher price tag 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 greater 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
Most solar installers in East Sandwich provide solar loans, which reduce the initial cost of installing solar.It’s a good idea to factor the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it’ll take to pay off the loan.
Solar Panel Installation Company
The solar company you go with to handle your switch to green energy can have an effect on your total costs. There are about 3 solar panel companies operating in East Sandwich, and each can charge different amounts 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 at a higher cost. It’s best to do some research and find a company that has the products, warranties and services you’re looking for and also is within your budget.
