Factors that Affect Solar Panel Costs in Rapid City

Cost is often one of the most important factors for homeowners who are considering investing in solar. There are a few primary factors that determine your overall cost in Rapid City: solar equipment and system size, financing options and the solar installation company you choose. We'll cover each of these briefly below.

Solar Equipment

When it comes to estimating the cost of a solar panel system in Rapid City, 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 consumption, which you can figure out by looking at past energy bills. Your overall cost can increase by around $2,390 for each additional kilowatt you need. There are a lot of different solar panel brands and the one you choose also changes the cost. Usually, the brands that have better efficiency tend to also be more expensive. In addition, the type of equipment you want to install can affect your total cost. If you only need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Most solar installers in Rapid City offer solar loans, which reduce your upfront costs of installing a solar system. It's wise to factor the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it'll take to pay back the loan.

Solar Panel Installation Company

The last significant cost factor you should keep in mind is the installer you choose. Given the booming popularity of sustainable energy solutions in Rapid City, you'll have many options to choose from, but each comes at different price points for labor and equipment. The size of the company can sometimes play the most considerable role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower prices because of more resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger companies.

How to Save on Solar Panels

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

  • Warranty: A comprehensive, 25-year warranty can help keep your solar panels running for a long time and save you money on part replacement and repairs.
  • Solar Panel Brands: Not all solar companies offer the same brands of solar panels, so the brand and type of panel you want can play a substantial role in the company you go with.
  • Reputation: Companies that have been in business for many years likely have a solid reputation. This is important because it ensures that it will not only see your solar project through, but will also provide adequate aftercare and customer service, such as part repairs and replacements.
  • Contract: Although reading through a contract can take a lot of time, it's important to do it carefully so you can make sure you understand how much the equipment and services will cost and the terms of the warranty.
