Factors that Affect Solar Panel Costs in South St. Paul
For many South St. Paul homeowners, the decision to install a solar energy system rests on cost. However, the range of solar installation costs can be quite wide in South St. Paul, with typical prices between $20,000 to $40,000. There are numerous factors that considerably influence the price you’ll pay, which we'll go over below.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of going solar. For that reason, it’s a priority to accurately ascertain the size of the solar energy system needed for your home by figuring out your average energy use.The type of solar panels and equipment you want is another factor that will largely affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to cost more. Further, solar equipment consists of more than just the solar panels themselves. You’ll also need to consider the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when searching for a solar system that’s in your budget.
Solar Financing Terms
For some homeowners, paying for solar panels out of pocket can be challenging. Solar loans are offered by most installers in South St. Paul, which can lower, or in some cases eliminate, your upfront costs to make solar more affordable.When considering your overall cost, you should also calculate the interest you’ll pay if you opt for a solar loan. Also, paying a higher down payment can reduce the total interest paid over time.
Solar Panel Installation Company
The final key cost factor you should take into consideration is the installer you choose. Given the growing popularity of renewable energy solutions in South St. Paul, you’ll have a great number of options to choose from, but each comes at various price points for labor and equipment.Some companies only sell high-quality, high-efficiency and high-price products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and go with the company that provides the products, warranties and services you want and also fit into your budget.

EcoWatch's South St. Paul, MN Solar Cost FAQs
What is the average cost of installing solar panels in South St. Paul?
This is a difficult question to answer exactly, because the cost depends on a few different factors. Broadly speaking, it costs about $20,150 for a 5-kW system and $40,300 for a 10-kW system after the ITC is applied. It will be more expensive if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy needs. On the flip side, you can spend less if you opt for a smaller solar panel system or less expensive solar panels.
Should I lease or buy solar panels in South St. Paul?
Leasing solar panels can be an option if you are unable to pay upfront or get a solar loan, but since you don’t own the system, you don’t have access to many solar incentives. Also your property value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most savings from going solar.
How much can I save on power bills after switching to solar?
It is possible to eliminate your electricity bills with solar panels, but for most homeowners throughout South St. Paul, that will require at least a 10-kW system. Not all homes will have roofs that can accommodate that size system, so you’ll want to check with a local solar installer to see how many panels can fit on your roof.
What solar power system size is right for my home?
To figure out what solar panel system size you need, you should find out how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
