Factors that Affect Solar Panel Costs in Williams

The cost of installing a solar system in Williams can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The biggest one is your system size, and other factors include equipment choices, financing options and the solar installer you choose.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to some different factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power generation use 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 $2,730. Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Williams, where sunlight is abundant, efficiency can quickly pay off. Plus, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Solar panels can save you money on power bills over many years, but they can also be a big investment. That's why many Williams homeowners opt to finance their solar panel systems to make paying for solar more affordable. However, the interest on solar loans also increases your overall costs, so it's vital to keep that in mind as well. You can always bring down the total you pay in interest and sometimes even your APR by putting more money down.

Solar Panel Installation Company

A final factor to consider when trying to evaluate the cost of solar for your home or business in Williams is the company you get to install your PV system. Similar to choosing a company to install new cabinets, for instance, there are plenty of solar installers that provide a range of services for different budgets. Companies that only sell products with high efficiency and therefore a higher price point — 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 offers the products, warranties and services you're looking for and also fits within your budget.

How to Save on Solar Panels

The solar installer you go with will be a major factor in determining not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are a few important things you should keep in mind, such as:

  • Solar Panel Brands: Each solar panel brand and kind offers varying levels of quality, longevity and energy efficiency. They will come at different prices as well. The company you choose plays a role in which solar panel brands you have access to.
  • Contract: Before you sign a contract with a solar company, be sure to read it through fully so you understand the terms. Also, ask questions if you're not sure about some of the terms, such as what the warranty covers and what services you can expect from them.
  • Reputation: Make sure your solar system installer has a good reputation by verifying it has certifications and licenses, checking its work history and reading reviews by past customers and solar experts like the EcoWatch team.
  • Warranty: An all-inclusive, 25-year warranty can help keep your solar system running smoothly and save you money on part replacement and repairs.
