In the world of solar energy, a recent development in Ann Arbor has sparked curiosity and raised some intriguing questions. The Veridian at County Farm, a housing project with a strong focus on sustainability, has implemented an unconventional approach to solar panel placement. This story delves into the rationale behind north-facing solar panels and explores the broader implications of this innovative design choice.
The North-Facing Mystery
When Mark Clevey, a prominent solar advocate in Ann Arbor, noticed north-facing solar panels on the rooftops of Veridian's new buildings, he was puzzled. Given the region's climate, north-facing panels typically receive less direct sunlight, making them less efficient. Clevey's initial assumption was that the developer had received poor advice.
However, the story takes an interesting turn. Matt Grocoff, a resident and solar advocate, explains that the north-facing panels are part of a comprehensive strategy. The Veridian development aims to optimize performance rather than maximize efficiency. By utilizing multiple roof sides for solar panels, the project creates a holistic energy system, much like the natural efficiency of a tree's leaf system.
A Different Perspective
Grocoff's analogy is thought-provoking. He highlights that Michigan's north-facing roofs are surprisingly productive during the summer months, a fact often overlooked. By incorporating north-facing panels, the development maximizes energy production during the sunnier seasons. This approach challenges the conventional wisdom that north-facing panels are less worthwhile.
The Bigger Picture
The Veridian development is designed to meet the Living Community Challenge's rigorous green building standards. Residents report significantly reduced energy bills, with some even generating excess energy. This success story showcases the potential of innovative solar strategies.
A Step Towards Net Zero
Local builder Doug Selby has taken a similar approach with his net-zero quadplex condo building. Selby's design incorporates solar panels facing all four directions, with the north-facing panels almost flat. While acknowledging the superior efficiency of south-facing panels, Selby emphasizes the improving technology and the overall energy generation potential of east- and west-facing arrays, and even the north-facing panels.
Conclusion
The story of north-facing solar panels in Ann Arbor is a testament to the power of innovative thinking in sustainable development. By challenging conventional wisdom and embracing a holistic approach, these projects are pushing the boundaries of what's possible in renewable energy. It's a reminder that sometimes, taking a step back and looking at the bigger picture can lead to remarkable solutions. As we continue to explore sustainable living, stories like these inspire us to think creatively and embrace new perspectives.
