Factors that Affect Solar Panel Costs in St Paul

The cost of installing a solar system in St Paul can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The largest one is your system size, and other factors include equipment choices, financing options and the solar company you choose.

Solar Equipment Size

The cost of solar panel systems varies by thousands of dollars due to some different factors. One of the most significant factors is the system size. Solar power systems with greater efficiency or power production require better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $2,840. The kind of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. On the other hand, higher efficiency could save you more over time on your energy bills. Additionally, extra products, such as solar batteries, can bring your total well above the St Paul average.

Solar Financing Terms

For some homeowners, paying for solar out of pocket can be financially overwhelming. Solar loans are provided by most installers in St Paul, which can reduce, or in some cases completely eliminate, your upfront costs to make solar more affordable. However, the interest on solar loans also increases your overall costs, so it's crucial to keep that in mind as well. You can always lower the total you pay in interest and sometimes even your APR by putting more money down.

Solar Panel Installation Company

The solar panel installation company you pick will play a role in your total cost to adopt solar energy. Different companies will bill different amounts for the equipment and labor. You may see national solar installers that have lower prices due to their larger brand name and access to bulk equipment pricing, or you might see small, local installation companies offering deals or specials to compete with those major players.

Broadly speaking, it costs about $14,200 for a 5-kW system and $28,400 for a 10-kW system after the ITC is applied. It will cost more if you want additional solar equipment or more efficient panels, or if you have higher-than-average energy consumption. Conversely, you can spend less if you opt for a smaller solar panel system or less efficient solar panels.

Are solar panels free in St Paul?
