Factors that Affect Solar Panel Costs in South Portland
For many South Portland homeowners, the decision to install solar panels rests on cost. However, the range of solar installation costs can be quite wide in South Portland, with typical prices between $20,000 to $40,000. There are a few factors that significantly influence the price you'll pay, which we'll go over below.
Solar Equipment
When it comes to estimating the price of solar panels in South Portland, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are chiefly based on your home's energy usage, which you can gauge by looking at past energy bills. Your total cost can increase by about $2,830 for each additional kilowatt you need. Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like South Portland, 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 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 financially overwhelming. Solar loans are offered by most installers in South Portland, which can bring down, or in some cases totally eliminate, your upfront costs to make solar more affordable. While solar loans make adopting solar energy more accessible for South Portland homeowners, they can also increase the total you pay for your system due to interest. If you make a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
The solar company you choose to handle your switch to solar energy can have an effect on your total costs. There are about 3 solar installation companies operating in South Portland, and each can charge varying amounts for labor and equipment. Some companies 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 cost more. It's best to do some research and decide on the company that has the products, warranties and services you're looking for and also fit into your budget.
