Comeback idea

A solar planning app that helps homeowners and small businesses size, compare and track rooftop solar systems.

The write-up

SolarWatt turns rooftop sunshine into a simple planning tool, and it's ready for a second act. Rising energy bills and renewed interest in home power make a friendly solar planning app a timely fit for homeowners weighing their options. It's up for a fresh start, so here's how you'd relaunch it: a mobile app with system sizing, savings estimates and installer matching, run from solarwattapp.com.
