Factors that Affect Solar Panel Costs in Janesville
For many Janesville homeowners, the decision to adopt solar energy depends on cost. However, the range of solar installation costs can be quite wide in Janesville, with typical prices between $20,000 to $40,000. There are various factors that considerably influence the price you’ll pay, which we'll go over below.
Solar Equipment
One of the most significant factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more power your household uses, the larger your system will likely need to be. You can expect to pay about $3,880 per kilowatt in Janesville.The brand of solar panels and equipment you choose is another factor that will largely affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to cost more. Furthermore, solar equipment is 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 looking for a solar system that’s in your budget.
Solar Financing Terms
For some homeowners, paying for solar panels out of pocket can be a challenge. Solar loans are available from most installers in Janesville, which can lower, or in some cases totally eliminate, your upfront costs to make solar more accessible.It’s wise to factor the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it’ll take to pay off the loan.
Solar Panel Installation Company
A final factor to keep in mind when trying to figure out the cost of solar for your home or business in Janesville is the company you hire to install your PV system. As with choosing a company to renovate your kitchen, for example, there are plenty of solar installers that offer a range of services at different costs.Additionally, some companies in Janesville know more about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels
The solar company you go with will influence not only your total costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are a few important things you should keep in mind, such as:
- Warranty: Warranties that cover defective panels and repairs over around 25 years are the gold standard in the business, and offering such a warranty is one indication of a good company.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a solid reputation and is qualified to install your solar system. Another way you can look into your installer’s reputation is by reading reviews.
- Solar Panel Brands: Not all solar installers carry the same brands of solar panels, so the brand and type of panel you want can play a substantial role in the company you opt for.
- Installation Process: Homeowners should understand how exactly the installation process will go, as well as important factors like the project timeline.
