What red flags should I watch for hiring a solar installer in Philadelphia?
In Philadelphia, verify your solar installation contractor pulls the permit themselves — never pull it in your own name. If they ask you to pull the permit, they may not be properly licensed to do the work. Be cautious of solar installation contractors in Philadelphia who pressure you to sign same-day. Legitimate contractors expect you to get competing bids and will hold their price for 30 days. High-pressure sales tactics correlate with inflated pricing. In Philadelphia, solar installation on homes over 46 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.
