Factors that Affect Solar Panel Costs in Helena
For many Helena homeowners, the decision to go solar comes down to cost. However, the range of solar installation costs can be quite wide in Helena, 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
The size of the solar system you need to offset your energy usage, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by about $3,470. Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like Helena, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or limited space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
For some homeowners, paying for solar panels out of pocket can be difficult. Solar loans are available from most installers in Helena, which can lower, or in some cases completely eliminate, your upfront costs to make solar more affordable.You’ll have to consider the long-term cost of financing options, including the amount of interest you’ll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or finding a solar loan with a low interest rate could reduce your costs considerably.
Solar Panel Installation Company
The solar panel installation company you select will impact your total cost to go solar. Different companies will bill different amounts for the equipment and labor.The size of the company can sometimes play the most considerable role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower pricing 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 names.
