Factors that Affect Solar Panel Costs in Grinnell

Cost is often one of the most important factors for homeowners who are considering investing in solar. There are a few key factors that affect your total cost in Grinnell: solar equipment and system size, financing options and the solar installation company you choose. We'll go over each of these briefly below.

Solar Equipment

When it comes to estimating the cost of a solar energy system in Grinnell, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home's energy consumption, which you can gauge by looking at past power bills. Your total cost can increase by around $2,770 for each additional kilowatt you need. Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Grinnell, where sunlight is relatively 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

If paying for solar panels in cash is out of reach, solar loans are a popular choice because they lower your upfront costs and let you pay for your system over a term of, on average, between five and seven years. Although solar loans make switching to solar energy more accessible for Grinnell homeowners, they can also increase the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The solar installer you choose will affect your total cost to go solar. Different companies will bill different amounts for the equipment and labor. 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 at a higher cost. It's best to do some research and find a company that has the products, warranties and services you want 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 selecting a company can be difficult, we have some tips to help you, such as:

  • Solar Panel Brands: Each solar panel brand and type has varying levels of quality, durability and efficiency. They will come at different costs as well. The company you choose plays a role in which solar panel brands you have access to.
  • Reputation: Your solar installer should have a sound reputation as a company and have verifiable expertise in the field. A couple of ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from previous customers.
  • Warranty: An all-inclusive, 25-year warranty can help keep your solar panels running for a long time and save you money on part replacement and repairs.
  • Contract: Even though reading through a contract can take a lot of time, it's important to do it thoroughly so you can make sure you understand what services your solar company will provide and how part repairs and replacements will be handled.
