Factors that Affect Solar Panel Costs in South Plainfield
Cost is usually one of the most important factors for homeowners who want to invest in solar. There are a few primary factors that will push your cost above or below the average in South Plainfield: solar equipment and system size, financing options and the solar installation company you choose. We’ll go over each of these briefly below.
Solar Equipment
When it comes to estimating the cost of a solar energy system in South Plainfield, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home’s energy usage, which you can figure out by looking at past energy bills. Your overall cost can increase by about $3,530 for each additional kilowatt you need.The type of solar panels and equipment you get is another factor that will significantly influence costs. Solar panels that are more efficient, like monocrystalline panels, tend to cost more. Plus, solar equipment goes beyond just the solar panels themselves. You’ll also need to decide on the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when researching a solar system that falls within your budget.
Solar Financing Terms
If paying for solar panels out of pocket is too expensive, solar loans are an affordable choice because they cut back your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.It’s wise to add the interest you’ll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and how long it’ll take to pay off the loan.
Solar Panel Installation Company
A final factor to keep in mind when trying to figure out the cost of solar for your home or business in South Plainfield is the company you get to install your PV system. Similar to choosing a company to build a deck or pool, for instance, there’s no shortage of solar installers that offer a range of services for different budgets.Larger national companies typically have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or extra services like electric vehicle charger installation, they might be cheaper overall.
