Factors that Affect Solar Panel Costs in Williamston

There are a number of factors that can affect your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.

Solar Equipment

When it comes to estimating the price of a solar system in Williamston, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are chiefly based on your home’s energy usage, which you can gauge by looking at past power bills. Your total cost can increase by around $3,450 for each additional kilowatt you need.The brand and kind of equipment you want for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often have a higher price tag than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

Most solar installers in Williamston have solar loans, which reduce your upfront costs 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 a higher down payment can lower the total interest paid over time.

Solar Panel Installation Company

Lastly, the company you opt for to install your solar panel system can affect your pricing. Williamston’s solar companies all have different labor costs and add varying upcharges to equipment. Some companies 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 at a higher cost. It’s best to do some research and go with the company that provides the products, warranties and services you’re looking for and also is within your budget.

How to Save on Solar Panels

The company that does your solar system installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Because picking a company can be difficult, we have some tips to help you, such as:

  • Solar Panel Brands: Different companies will have various brands and types of panels. If you prefer a specific brand, make sure the solar panel installer you’re considering has it.
  • Contract: Before you sign a contract with a solar company, be sure to look it over carefully 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.
  • Warranty: Each company may offer different kinds of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
  • Installation Process: One of the most important things to understand when adopting solar power is the installation process itself. Be sure to clarify any details you need to know with your solar installer, such as what permits you should acquire and how long the project will take.
