Designing Solar Ready Homes

Key Construction and Coordination Concepts for Builders and Architects

When designing or constructing a new home, garage, or other structure, integrating solar considerations early in the process makes all the difference. Collaboration between the builder, architect, and solar contractor ensures that the roof, electrical system, and structural layout are solar ready from day one.

Thoughtful planning at this stage simplifies installation, avoids rework, and delivers lasting value for your clients. Early coordination on solar ready home design helps ensure roof layout, electrical routing, and structural framing are optimized for long term performance.

Schematic Solar Ready Home Design Considerations

Orientation:

Roof orientation is one of the most critical aspects of solar design. A roof that faces as close to due south as possible maximizes sunlight exposure and system performance. While other orientations can still produce strong results, especially with modern equipment and high efficiency panels, south-facing roofs remain the most effective choice for Rhode Island’s solar conditions. Coordinate with your solar partner to select the roof plane that best balances performance, aesthetics, and available roof space.

Pitch (roof slope):

The slope of the roof affects seasonal energy capture. A practical rule of thumb is to align roof pitch near site latitude. In Rhode Island a slope between about 30 and 45 degrees provides strong year-round performance. Orientation and shading typically have a greater impact on output than small variations in pitch, so prioritize direction and shade control first.

Shading:

Solar-ready design minimizes shade on array zones from trees, chimneys, dormers, parapets, and adjacent structures. During schematic design, review sun paths or request a shading analysis from your solar partner to confirm the usable roof planes. If landscaping includes trees near the home, specify species that remain low in height and preserve southern exposure.

The example below illustrates how solar modeling software evaluates roof orientation, pitch, and surrounding shade to guide early design decisions.

3D solar modeling helps identify shading impacts early in the design process, ensuring every home is built solar ready.

Design Development Considerations

Obstructions and roof penetrations:

Plan early for skylights, dormers, chimneys, and vent stacks to preserve clear array space. When possible, place them on non-south-facing roofs. If south-facing penetrations are unavoidable, group them near the ridge or edges to maintain contiguous panel layout. Confirm final locations with your solar partner before construction documents are issued.

Roof type and framing:

Asphalt shingles and standing seam metal are efficient substrates for racking. Standing seam metal supports clamp-on attachment that avoids penetrations and protects the roof surface. Framing with a 2x6 top chord provides robust support and spacing for most racking systems, often reducing penetrations and installation time.

Electrical planning:

Integrating electrical planning early prevents field changes and ensures compliance with utility interconnection standards. Coordinating between the builder, electrician, and solar contractor during design helps keep field work efficient and organized while supporting a clean, professional installation that aligns with solar ready home design principles.

• Keep the utility meter accessible for interconnection work.

• Reserve space from the service equipment to the meter location for solar conductors and communication wiring.

• Use a meter-main combination panel whenever possible, and ensure the main electrical panel inside the home includes a main breaker. This configuration simplifies interconnection, improves safety, and meets most utility and code requirements.

• If the array will be on a detached structure, install spare PVC conduits during trenching rather than reopening later.

• Confirm current utility program metering requirements with your solar partner since some programs require additional metering or production-meter sockets.

Battery design:

If the project may include battery storage, plan for battery location early. Discuss whether the equipment will be installed indoors or outdoors and allocate sufficient wall space and clearances. Consider ventilation, temperature, and accessibility for maintenance. Including conduit paths and service disconnects in the initial design helps streamline installation when storage is added later.

Energy efficiency integration

Pair solar with an efficient building envelope. Air sealing, insulation, high-performance windows, and efficient HVAC reduce the required system size and improve overall project value. Aligning energy efficiency upgrades with solar design supports better outcomes for clients.

Construction Phase Coordination

Wiring and equipment access

Coordinate electrical rough in before drywall and finishes so conduit and homeruns are concealed and equipment locations are reserved. Identify space in the mechanical or utility room for the inverter, disconnects, rapid shutdown equipment, and monitoring components. Pre-planning yields a cleaner installation and better serviceability.

Pre-wiring and early coordination between teams streamlines installation and maintains a clean finished look.

Scheduling and workflow

Invite the solar contractor to pre-construction meetings to align on structural loads, roof access, safety tie-offs, crane needs, and sequencing. Clear communication minimizes change orders and keeps milestones on schedule.

Financing and appraisal support

Many lenders recognize solar as an asset in new construction appraisals. Integrating the system into project financing can streamline closing and improve long-term cash flow for owners. Ask your solar partner for documentation that supports valuation and current incentive eligibility.

Working as one team

Solar integration is most effective when builders, architects, and solar professionals work together from the start. Early coordination protects design intent, elevates aesthetics, and delivers systems that perform as beautifully as they look.
