What is the ideal roof pitch and location for solar on my new home?
A 7/12 roof pitch with southern exposure is optimal for roof-mounted solar arrays. Systems can also be installed on various roof pitches and east or west-facing roofs. More panels may be required to achieve energy goals.
Should I plan to install conduit for future wiring of my solar array?
Yes, installing a 2” metallic conduit from the attic to the electrical load center during construction saves money and simplifies solar array installation.
Should I be concerned about the placement of buried private or public utility lines during the construction process?
Yes, keep utility lines out of the trench path for future ground-mounted solar arrays to reduce labor costs and ensure safety.
Should I prepare a site for my ground-mounted solar array during the new construction process?
Yes, prepare a flat area approximately 50' x 20' for a residential array to save on installation costs and optimize energy production.
What size of an electrical load center should I install in my new home to prepare for solar in the future?
A 225A Square D Homeline load center with a 200A main breaker is recommended. Ensure two free slots for the solar breaker.
Should I plan for any extra space required for solar equipment inside or outside the home?
Leave about 4' of wall space inside the home near the load center for the inverter and 3' of exterior wall space near the utility meter for the utility disconnect.
Should I plan for any additional networking infrastructure for monitoring my future solar array?
Place your internet router near the load center for easy connectivity of the solar array inverter.
Do I need to plan any extra space for the placement of a future battery?
Leave 5' of wall space near the load center for a future battery, plus 4' for the inverter.
Should I consider the placement of new or existing trees when planning for my future solar array?
Consider the future size of trees to avoid shading solar panels. Contact Arrow Solar for advice on tree placement.
