Going Solar?
Whether you simply want to learn the benefits of adding solar to your home or if you are ready to make a solar system investment, it’s often difficult to know how to begin. We’re here to help provide you with unbiased, factual information to help you no matter what stage of the process you are in.
Is Solar the Right Choice?
In order to determine if adding solar to your home is the right decision for your unique situation, be sure to do your homework and identify all of your solar options.

Some questions you may want to ask yourself before you begin:
  • What is your goal for installing solar?
  • How much of your annual energy use do you want to offset?
  • Should you go with a ground or roof mounted system?
  • Is your roof (materials and structure) in an acceptable condition to have solar installed?
  • Will your solar system be in a shaded spot through part of the day or at certain times of the year?

If you determine that a solar energy system won’t work for your home, you can still power your home with renewable energy by enrolling in our Choose Renewable! program.

Getting Started
Stoughton Utilities wants your solar project to be a successful journey. It's a big project, and there's a lot of steps to ensure a smooth process. Once you decide to invest in solar at your home, follow these steps to ensure you get a correctly installed solar system.
Contact local solar installation contractors
One of the most important steps to a successful solar energy system is finding the right contractor. We recommend you always obtain multiple quotes and compare the total costs and payback periods of different systems and installers.

Stoughton Utilities does not endorse any contractor or warrant any workmanship, installation, labor, cost or materials of any contractor. Stoughton Utilities also does not work exclusively with any specific solar contractor, or offer any special programs for any contractors. Be cautious if anyone says they are working for, or affiliated with Stoughton Utilities during a home visit or sales presentation.

There are a number of online resources to help you find and research potential contractors.
Tips for Hiring a Contractor
  • Hire only a WI-State Licensed contractor with a valid license. Consider installers with North American Board of Certified Energy Practitioners (NABCEP) certification.
  • We recommend obtaining at least three system proposals and price quotes. Be sure to check the customer references provided, and consider asking about the company on social media.
  • Obtain a written project proposal and review the project expectations, including the solar system’s expected annual output.
  • Confirm the contractor carries worker’s compensation and liability insurance policies.
  • Review and verify any information you are provided regarding payback periods and electric rate information.
  • Review and verify that the contractor has obtained all required building and electrical permits.
  • Make sure Stoughton Utilities has approved the solar PV system for interconnection to our electrical distribution system before you sign off on the project or make payment.

Installation and inspection
If requested by your solar installer, Stoughton Utilities will schedule a planned disconnection of your electrical service to allow the electrician to safely complete their work in your service panel or meter socket.

Upon installation completion of your solar system, a final inspection by the city or township building inspector is required. If you live in the city, contact Stoughton City Hall at (608) 873-6677 for questions regarding inspections. Rural customers should contact their township for inspections.

System commissioning
Stoughton Utilities does not typically require a formal commissioning process for most residential solar installations. Larger systems, including residential systems over 20 kW, multi-phase systems, and non-residential systems may require formal utility commisioning, including inspection and anti-islanding testing. Stoughton Utilities reserves the right to require a formal utility commissioning for all systems, including standard residential systems.

Following commissioning (or commissioning exemption), Stoughton Utilities will issue a fully-executed interconnection agreement that provides you with permission to energize your new system. You are prohibited from energizing your new system prior to the utility providing you with a fully executed interconnection agreement and authorization to energize.
