This quick guide is a streamlined overview for planning and building smarter, solar-ready homes.

1. Why Plan Solar Before Construction

Solar integration is most effective when included during design and construction—not after. Early planning lets you:

• Optimize roof orientation and tilt for maximum sunlight capture
• Integrate electrical infrastructure efficiently.
• Avoid costly retrofits and roof penetrations
• Increase energy performance and home resale value.

Benefit Summary:

• Lower lifecycle energy costs
• Greater home market appeal
• Reduced carbon footprint

2. Key Elements in Early Design

Roof Design

• Favor large, south-facing roof planes with minimal shading
• Avoid complex roof geometry that limits panel placement
• Plan for optimal tilt roughly equal to latitude for peak annual output

Orientation & Shading

• Maximize solar exposure
• Minimize shading from trees, chimneys, or roof objects

Structural & Electrical

• Allow space for conduit runs and future panels
• Design service panels with higher amperage capacity for EVs and batteries
• Plan inverter and meter locations early for cleaner integration

3. System Options & Where to Put Them

4. Contractors’ Pre-Construction Tasks

Coordinate early with a solar professional to:

• Perform a site solar analysis to set expectations
• Identify permit and code requirements
• Ensure roof framing accounts for solar conduit needs
• Core foundation for conduits to avoid later drilling

5. Where to Go Next
