A GUIDE TO MICHIGAN SOLAR SOLUTIONS: INTEGRATING PHOTOVOLTAICS IN NEW BUILDING PROJECTS
Solar photovoltaics (PV) have become a major consideration in new construction projects across the country, and Michigan is no exception. With the push for sustainability and reduced energy costs, architects now have an opportunity to incorporate solar into building designs from the earliest stages. While architects excel at creating functional and aesthetically pleasing structures, understanding how to design PV systems to maximize client value is essential. This guide offers insights into designing solar PV systems for new construction in Michigan.
Understanding Client Motivation for Solar
The first step in designing PV systems is understanding the client’s motivation. Different clients have different goals, and knowing these early will inform system design and placement. Commercial clients may emphasize marketing and visibility, wanting solar panels prominently displayed to highlight sustainability. Other clients may have regulatory or licensing requirements that mandate a certain level of PV energy generation for their building to operate legally in a community.
Using tools like PVWatts, architects can estimate system size and potential energy production. They must also evaluate whether a rooftop, ground-mounted, or carport system is the most effective solution. Collaborating with local installers early in the design process ensures that architects understand what solutions are feasible, what products are available, and how local building and electrical codes affect installation. For instance, some jurisdictions may require certain wind-load or snow-load specifications for panel mounting.
Rooftop Solar Design Considerations
When integrating solar on a rooftop, shading is a critical factor. Panels should be placed away from HVAC units, parapets, and other obstructions to maximize sunlight exposure. A good rule of thumb is maintaining a two-foot setback from each vertical foot of height of a shading object, particularly to avoid shading during the December solstice.
Orientation also matters. South-facing rooftops offer the highest energy production, while east and west orientations can still be effective. North-facing panels should generally be avoided due to reduced efficiency. For flat roofs, panels are typically installed in landscape orientation to maximize energy production. Architects should consider roof load capacity, potential future expansion, and maintenance access when planning rooftop PV systems.
Ground-Mounted and Carport Solar Options
When rooftop installation is insufficient or not feasible, ground-mounted and carport solar arrays provide viable alternatives. Ground-mounted systems are generally more cost-effective than carports, though they require careful placement near the building’s main electrical service to avoid high trenching or wiring costs. Panels should be tilted at approximately 30 degrees and spaced to prevent shading between rows, ensuring consistent year-round production.
Carports offer additional advantages, particularly when paired with EV charging stations. They can span multiple parking spaces and provide continuous shading while generating electricity. Carports can also be designed with water-permeable or impermeable surfaces depending on client requirements, and steel frames can be painted to match building aesthetics, improving curb appeal while serving a dual purpose.
Building-Integrated PV (BIPV) Considerations
BIPV refers to solar materials that serve both as building elements and energy generators. Examples include solar shingles, translucent PV glass, skylights, and awnings. While BIPV technology is still emerging, it can make a strong statement about a client’s commitment to sustainability. Some products, such as solar shingles, were offered by companies like RGS under license from Dow Chemical, though widespread adoption has been limited. Current BIPV innovators include Onyx and Lumos Solar, offering solutions for windows, skylights, and architectural glass. Architects considering BIPV should weigh aesthetics, energy output, and cost-effectiveness.
Collaboration with Solar Contractors
For architects, forming strategic alliances with experienced solar contractors is critical to successfully integrating PV into building projects. Solar contractors bring practical knowledge of system sizing, installation methods, and product availability. By collaborating early, architects ensure that their designs align with real-world constraints and maximize value for clients. Michigan Solar Solutions welcomes these strategic partnerships, providing guidance and expertise for integrating PV into new construction.
Optimizing PV System Performance in Michigan
Michigan’s climate and latitude influence solar system performance. Architects should consider seasonal sun angles, snow load, and potential shading from surrounding buildings or vegetation. Ensuring optimal tilt, orientation, and spacing of panels will maximize energy production and client return on investment. Additionally, integrating solar in the early design phase allows for better coordination with roof penetrations, mechanical systems, and aesthetic elements.
Client Value and Marketing Opportunities
Incorporating solar provides tangible benefits for clients. Energy cost savings, sustainability credentials, and marketing advantages are key value drivers. For commercial buildings, visible PV installations can enhance public perception and attract eco-conscious tenants or customers. Ground-mounted and carport systems offer opportunities for branded experiences, such as EV charging stations powered by solar, demonstrating environmental leadership to the community.
Next Steps for Architects
Architects looking to integrate solar into Michigan construction projects should begin by understanding client goals, assessing site potential, and consulting with solar contractors. Evaluating rooftop, ground-mounted, and BIPV options ensures that designs maximize energy production, cost-effectiveness, and aesthetics.
