Factors that Affect Solar Panel Costs in Sun Prairie

There are several criteria that can play into your 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

Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. Because of that, it's crucial to accurately assess the size of the solar energy system needed for your home by figuring out your average energy use. There are many different solar panel brands and the one you choose also affects the cost. In general, the brands that are more efficient tend to also be more expensive. Additionally, the type of equipment you're looking to install can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for a solar system out of pocket is difficult, solar loans are an affordable option because they decrease your upfront costs and let you pay for your system over five to seven years on average. However, the interest on solar loans also adds to your all-in costs, so it's vital to include that in your estimate as well. You can always bring down the total you pay in interest and possibly even your APR by putting more money down.

Solar Panel Installation Company

The last major cost factor you should consider is the installer you choose. Given the growing popularity of clean energy solutions in Sun Prairie, you'll have plenty of options to choose from, but each comes at different price points for labor and equipment. Additionally, some companies in Sun Prairie know more about local solar incentives and can help you make good use of additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

There are numerous companies available in Sun Prairie, and some homeowners feel overwhelmed considering their options. Selecting the right company for you can be tough, so here are some tips to help you decide:

  • Contract: Although reading through a contract can take a lot of time, it's important to do it fully so you can be sure you understand how much the equipment and services will cost and the terms of the warranty.
  • Solar Panel Brands: Each solar panel brand and type offers varying levels of quality, durability and energy efficiency. They will come at different price points as well. The company you choose has an impact on which solar panel brands you have access to.
  • Warranty: A quality company rises above other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Installation Process: Get detailed information from your solar company about the installation process and what to expect, including when the site survey will be completed and how long it will take.

EcoWatch's Sun Prairie, WI Solar Cost FAQs

How much does it cost to install solar panels in Sun Prairie?

The average cost of solar panels in Sun Prairie is about $13,000 for a 5-kW system and $26,000 for a 10-kW system before the ITC, but the real cost will depend on things like the kind of solar panels you want, what size system you need and how much energy you use.

Is it better to lease or buy solar panels in Sun Prairie?

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 can't take advantage of many solar incentives. Also your home 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 financial benefits from going solar.

Can solar panels completely eradicate my energy bills?

Solar panels can potentially eliminate your electricity bills depending on where you're located and how much sunlight your home gets. Even if it doesn't get rid of them completely, you can save a lot of money on your bills, about $1,091.48 per year.

How many solar panels do I need to power my home?

To figure out how many solar panels you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
