Our founder set up Hao Solar in 2023 to do solar and EV charging properly for Singapore homes: measured on site, designed and simulated before quoting, installed by a team he trained, and looked after once the meter is in.
Today, the company has grown to build solar and EV charging systems for residential landed homes, measured on site, carefully designed and optimised before installing. It holds a 5.0 rating on Google from the customers it has served so far.

On the roof

On the driveway
Your own filling station, powered by your roof and your battery. Fitted by the same electricians who fit the panels, so the whole system works as one.
Against the wall
Bottles the afternoon sun for the evening, when your aircon and the family are home. Starts at 5 kWh and stacks to 15 kWh as the household grows.
