Factors that Affect Solar Panel Costs in Seneca
Though the average cost of a solar system in Seneca is $19,484, your actual cost may differ. There are many factors that can have a sizable impact on the cost of a residential solar panel installation. Below are some of the more crucial things to keep in mind.
Solar Equipment
System size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of installing solar panels. That’s why it’s crucial to accurately assess the size of the solar energy system needed for your home by figuring out your average energy use.The brand of solar panels and equipment you want is another factor that will greatly affect costs. Solar panels that are more efficient, like monocrystalline panels, tend to come at a higher price. Moreover, solar equipment is more than 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 looking into a solar system that’s in your budget.
Solar Financing Terms
Solar panels can save you money on utility bills over time, but they can also be a big investment. That’s why many Seneca homeowners opt to finance their solar panel systems to offset upfront costs.When figuring out your overall cost, you should also calculate the interest you’ll pay if you go with a solar loan. Also, paying more on your down payment can lower the total interest paid over time.
Solar Panel Installation Company
Finally, the company you get to install your solar panels can impact how much it costs. Seneca’s solar companies all have different labor costs and add varying upcharges to equipment. Some companies only sell high-quality, high-efficiency and high-price products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and find a company that provides the products, warranties and services you want and also fits within your budget.

How to Save on Solar Panels
The company that does your solar system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Because choosing a company can be difficult, we have some tips to help you, such as:
- Contract: Look through the contract terms carefully to make sure you understand the overall cost, project completion timeline rebates and warranties.
- Solar Panel Brands: Each solar panel brand and model offers varying levels of quality, durability and efficiency. They will come at different prices as well. The company you choose impacts which solar panel brands you have access to.
- Reputation: Your solar installer should have a solid reputation as a company and have verifiable expertise in the field. Two ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from previous customers.
- Warranty: A quality company rises above other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
