FOR SOLAR COMPANIES Walk the site, document the array, and hand the homeowner a customer ready proposal on the spot. Log defects on annotated photo cards so nothing gets lost between the roof and the office. Compare measured production against PVWatts estimates so customers see real output next to what they were promised. Every report carries your logo and contact details. FOR HOME INSPECTORS Add a solar inspection service worth $275 to $350 per visit. Certification training is included, so you can learn the method and start offering it right away.
