Factors that Affect Solar Panel Costs in Rapid City

For many Rapid City homeowners, the decision to install solar panels rests on cost. However, the range of solar installation costs can be quite wide in Rapid City, with typical prices between $20,000 to $40,000. There are various factors that greatly influence the price you'll pay, which we'll go over below.

Solar Equipment

When it comes to estimating the price of a solar panel system in Rapid City, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home's energy usage, which you can figure out by looking at past electricity bills. Your overall cost can increase by about $2,390 for each additional kilowatt you need.Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like Rapid City, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, 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 energy bills over many years, but they can also be a big investment. That's why many Rapid City homeowners opt to finance their solar panel systems to make going solar more affordable.However, the interest on solar loans also adds to your all-in costs, so it's crucial to consider that as well. You can always bring down the total you pay in interest and in some cases even your APR by putting more money down.

Solar Panel Installation Company

Finally, the company you get to install your solar panels can influence your pricing. Rapid City's solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies generally have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.
