Factors that Affect Solar Panel Costs in St. Louis Park
There are several factors that can play into your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.
Solar Equipment
When it comes to estimating the price of solar panels in St. Louis Park, 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 gauge by looking at past power bills. Your total cost can increase by about $4,030 for each additional kilowatt you need.The brand and type of equipment you want for your solar system can raise or lower the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Also, if you want additional equipment like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
For some homeowners, paying for solar panels out of pocket can be financially overwhelming. Solar loans are available from most installers in St. Louis Park, which can bring down, 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 go with a solar loan. Also, paying more upfront can lower the total interest paid over time.
Solar Panel Installation Company
The solar company you choose to handle your switch to sustainable energy can have an effect on your total costs. There are about 3 solar panel companies operating throughout St. Louis Park, and each can charge different amounts for labor and equipment.Some companies only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It’s best to do some research and decide on the company that provides the products, warranties and services you’re looking for and also fit into your budget.

How much can I save on electricity bills after switching to solar?
It is possible to erase your electricity bills with solar panels, but for most homeowners in St. Louis Park, that will require at least a 10-kW system.

How long do solar panels last in St. Louis Park?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can choose to replace them once you've had them for that long or you can continue to use them at a lower efficiency.
