Factors that Affect Solar Panel Costs in Grant

Though the average cost of a solar system in Grant is $16,643, your actual cost may be higher or lower than that. There are quite a few factors that can have a sizable impact on the cost of a solar system installation. Below are some of the more crucial things to consider.

Solar Equipment

One of the most important factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more energy your household uses, the larger your system will likely need to be. You can expect to pay about $3,760 per kilowatt in Grant.The brand and kind of equipment you choose for your solar system can raise or lower the price quite significantly. If you prefer a 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 can expect a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Solar panels can save you money on energy bills over time, but they can also be a big investment. That’s why many Grant homeowners decide to finance their solar panel systems to offset upfront costs.However, the interest on solar loans also adds to your all-in costs, so it’s crucial to keep that in mind as well. You can always reduce the total you pay in interest and in some cases even your APR by making a larger down payment.

Solar Panel Installation Company

Finally, the company you get to install your solar panel system can affect how much you pay. Grant’s solar companies all have different labor costs and add varying upcharges to equipment. 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 go with the company that offers the products, warranties and services you’re looking for and also fit into your budget.

How to Save on Solar Panels

Since the model of solar panels and the company you choose has an impact on your costs and your system’s durability and efficiency, it’s important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:

  • Contract: Look through the contract terms thoroughly to make sure you understand the cost breakdown, completion timeline rebates and warranties.
  • Warranty: If you’re concerned about the durability of your solar energy system, ensuring your company offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Installation Process: Make sure you’re on the same page with the company in regard to how the installation process will go and what you need to do before your solar system is installed, such as updating your electrical system or roof.
  • Solar Panel Brands: The type of solar panel you’d like to install plays a role in which installer you should opt for, since different companies provide different panels.
