| Region | PSH/Day | Annual kWh/kW |
|---|---|---|
| Southwest | 5.5-6.5 | 1600-2000 |
| Southeast | 4.5-5.5 | 1300-1600 |
| Northeast | 3.5-4.5 | 1000-1300 |
De-energize and lock out before any wiring work — DC from panels is always live in sunlight.
Even partial shade on one panel reduces entire string output — survey at multiple times of day.
Buy materials during off-season sales — prices drop 20-40% outside peak demand periods.
Crucial code requirements, material risk alerts, and prevention checklists for Rooftop Solar Assessment Guide.
⚠️ Risk Warning: Purchasing net calculated material causes project delays when cuts or breakage occur.
💡 Prevention Action: Always add a 10%-15% buffer allowance to initial calculated quantities.
⚠️ Risk Warning: Applying finishes to dusty or uneven surfaces reduces adhesion by up to 60%.
💡 Prevention Action: Vacuum, prime, and check levelness (max 1/8" gap over 10 ft) before starting.
