Sentinel Solar Roof Pump

MONEY-SAVING PRODUCT WINNER

The Sentinel Solar Roof Pump uses a 20W solar panel to power a 400-gph pump as a solution to ponding water on flat roofs.

Installing in minutes with no holes or electricity, it offers an alternative to electric sump pumps, re-pitching and re-decking to solve the ponding issue, or installing a costly roof drain. Its battery backup system can pump water for up to 30 days without sunlight.
