Factors that Affect Solar Panel Costs in Lake St Louis
The cost of installing a solar system in Lake St Louis 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 the equipment you choose, financing options and the solar installer you choose.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. For that reason, it's crucial to accurately ascertain the size of the solar energy system needed for your home by figuring out your energy needs. The solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you choose 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, more efficient panels could save you more in the long run on your power bills. Additionally, extra products, such as solar batteries, can bring your total well above the Lake St Louis average.
Solar Financing Terms
Most solar installers in Lake St Louis have solar loans, which reduce the initial cost of installing solar panels. However, the interest on solar loans also increases your all-in costs, so it's crucial to consider that as well. You can always reduce the total you pay in interest and possibly even your APR by putting more money down.
Solar Panel Installation Company
The solar panel installer you choose will play a role in your total cost to make the switch to solar energy. Different companies will bill different amounts for the equipment and labor. Additionally, some companies in Lake St Louis have more knowledge about local solar incentives and can help you make good use of additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.
