Factors that Affect Solar Panel Costs in Fairfax Station
For many Fairfax Station homeowners, the decision to install a solar energy system depends on cost. However, the range of solar installation costs can be quite wide in Fairfax Station, with typical prices between $20,000 to $40,000. There are various factors that considerably influence the price you’ll pay, which we'll go over below.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to a few different factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems with better efficiency or power generation require better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,590.There are many different solar panel brands and the one you choose also affects the cost. Generally, the brands that have better efficiency tend to also be more expensive. Plus, the type of equipment you want to install can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
For some homeowners, paying for solar out of pocket can be a challenge. Solar loans are offered by most installers in Fairfax Station, which can bring down, or in some cases completely eliminate, your upfront costs to make solar more affordable.When figuring out your overall cost, you should also calculate the interest you’ll pay if you decide on a solar loan. Also, paying more on your down payment can lower the total interest paid over time.
Solar Panel Installation Company
The solar company you select will impact your total cost to go solar. Different companies will charge different amounts for the equipment and labor.Some companies only sell high-efficiency and high-priced products — 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 go with the company that provides the products, warranties and services you want and also fit into your budget.
