How does Westfield's winter climate affect solar system size and configuration selection?

What red flags should I watch for hiring a solar installer in Westfield?
Watch for solar installation quotes in Westfield that lack line-item detail. A professional estimate breaks out labor, materials, permits, and cleanup separately. Lump-sum bids hide margin and make change orders impossible to evaluate. Check that any Westfield contractor doing solar installation carries both general liability insurance ($1M minimum) and workers' compensation. Request certificates directly from the insurer, not just copies the contractor provides. In Westfield, solar installation on homes over 45 years old should include a contingency line item (10-15% of total). Contractors who guarantee fixed pricing on old-home work either haven't looked closely enough or plan to cut corners when surprises appear.
