Factors that Affect Solar Panel Costs in Watertown

Cost is often one of the most important factors for homeowners wanting to invest in solar. There are a few primary factors that will push your cost above or below the average in Watertown: solar equipment and system size, financing options and the solar installation company you choose. We’ll discuss each of these briefly below.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. Because of that, it’s crucial to accurately assess the size of the solar energy system needed for your home by figuring out your typical energy use.The type of solar panels and equipment you want is another factor that will largely influence costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more costly. Moreover, solar equipment goes beyond just the solar panels themselves. You’ll also need to make decisions about the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when searching for a solar system that’s in your budget.

Solar Financing Terms

Most solar installers in Watertown have solar loans, which reduce the initial cost of installing solar panels.When estimating your overall cost, you should also calculate the interest you’ll pay if you opt for a solar loan. Also, paying more on your down payment can reduce the total interest paid over time.

Solar Panel Installation Company

The solar installer you choose will affect your total cost to make the switch to solar power. Different companies will bill different amounts for the equipment and labor.Larger national companies usually have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.
