Factors that Affect Solar Panel Costs in Green Bay
Though the average cost of a solar system in Green Bay is $18,890, your actual cost may be above or below the average. There are many factors that can have a significant impact on the cost of a residential solar panel installation. Below are some of the more important things to take into consideration.
Solar Equipment
The size of the solar panel system you need for your household, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by around $3,880. The brand and type of equipment you get for your solar system can raise or lower the price quite significantly. If you prefer a brand name like Tesla or SunPower, these are often more expensive 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 can expect a higher equipment cost, but this can typically lead to more savings over time. Also, if you want extra equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
For some homeowners, paying for a solar system out of pocket can be difficult. Solar loans are offered by most installers in Green Bay, which can reduce, or in some cases eliminate, your upfront costs to make solar more accessible.However, the interest on solar loans also increases your total costs, so it’s important to include that in your estimate as well. You can always lower the total you pay in interest and in some cases even your APR by putting more money down.
Solar Panel Installation Company
A final factor to keep in mind when trying to evaluate the cost of solar for your home or business in Green Bay is the company you hire to install your PV system. As with choosing a company to renovate your kitchen, for example, there’s no shortage of solar installers that provide a range of services for different budgets.The company’s size sometimes plays the most significant role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower prices because of greater resources and bulk pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing lower to compete with bigger companies.

How to Save on Solar Panels
The company that does your solar system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Because selecting a company can be a challenge, we have some tips to help you, 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 mark of a good company.
- Contract: Read the contract terms carefully to make sure you understand the cost breakdown, completion timeline incentives and warranties.
- Installation Process: Make sure you’re on the same page with the installer with regard to how the installation process will go and what you need to do before your solar panels are installed, such as updating or replacing your electrical system or roof.
- Reputation: Your solar installer should have a good reputation as a company and have demonstrated expertise in the field. Two ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from previous customers.
