Ann Arbor, Michigan, has launched a pilot project to install solar panels and battery storage in 150 homes, aiming to lower electricity bills and promote clean energy. Managed by municipal utility A2SEU in partnership with FranklinWH, the initiative could become a blueprint for other US cities.
Ann Arbor, Michigan, has kicked off a pioneering project to equip 150 homes with rooftop solar panels and home batteries, aiming to cut electricity bills and provide clean energy. The initiative, managed by the city’s sustainable energy utility A2SEU in partnership with energy management firm FranklinWH, is a real-world test of a model that could be replicated in other cities.
What does the project include?
Each participating home will receive a complete solar-plus-storage system featuring FranklinWH smart batteries. These batteries store excess solar energy generated during the day for use at night or during peak demand periods. The primary goal is to reduce residents’ electricity bills while decreasing reliance on the traditional power grid. According to Electrek, installations began this week and will proceed in phases.
Why Ann Arbor? What’s the community benefit?
Ann Arbor is known for its ambitious environmental policies and aims to be a model for sustainable cities. The project not only saves money for residents but also collects real-world performance data to improve system design and future expansion. Additionally, it eases strain on the grid during peak hours.
How does the system work?
The system combines rooftop solar panels with FranklinWH’s intelligent batteries. During the day, panels generate electricity, and surplus is stored in the batteries. In the evening or during outages, stored energy is used. An energy management software optimizes consumption distribution efficiently.
When could this model reach other cities?
The project is in its initial pilot phase, but success could encourage other US cities to adopt similar models. With rising electricity prices and growing interest in clean energy, such initiatives are expected to expand in the coming years.
Is this project suitable for the Gulf climate?
Although designed for Michigan’s cold climate, the components (solar panels and batteries) are applicable in Gulf countries, especially given abundant sunlight. However, high temperatures can affect battery efficiency, requiring additional cooling systems. Subsidized electricity rates in the Gulf may also extend payback periods.
Key facts
- City: Ann Arbor, Michigan, USA

Frequently asked questions
How much does the system cost for participating homes?
The city has not disclosed the exact cost per home. The project is partially funded by A2SEU’s budget and government grants. Residents are expected to cover a small portion, with investment recovered through electricity bill savings.
Can this project be implemented in Saudi Arabia or the UAE?
Theoretically, yes. Gulf countries have high solar irradiance, making solar panels very effective. However, batteries must be adapted for high temperatures, possibly requiring cooling systems. Subsidized electricity rates may lengthen payback periods.
What’s the difference between this project and ordinary home solar systems?
The key difference is that this project is managed by a municipal utility (A2SEU) rather than individuals, allowing unified data collection and performance optimization. The FranklinWH batteries feature smart energy management that efficiently distributes consumption.
