Factors that Affect Solar Panel Costs in Westmont
The cost of installing a solar system in Westmont can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The largest one is your system size, and other factors include the equipment you choose, financing options and the solar installer you choose.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power generation need 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 $3,760.The type of solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you opt for the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. On the other hand, higher efficiency could save you more over time on your energy bills. Additionally, extra products, such as solar batteries, can bring your total well above the Westmont average.
Solar Financing Terms
Many homeowners find the average cost of solar in Westmont to be too steep, even if the investment pays off over time. Fortunately, almost every solar installer in the area offers financing options. Solar loans substantially decrease upfront costs in most cases, but they also result in a higher cost over time because of interest.You’ll have to consider the long-term cost of financing options, including the amount of interest you’ll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or finding a solar loan with a low interest rate could reduce your costs significantly.
Solar Panel Installation Company
The solar installation company you pick will play a role in your total cost to go solar. Different companies will charge different amounts for the equipment and labor.Additionally, some companies in Westmont know more about local solar incentives and can help you make good use of additional rebates or tax exemptions. Though, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.
