“Brad Donovan started Donovan Electrical Service over 25 years ago and spent a large amount of that time working with BP Solar in both off grid and on grid installation.

We have worked with BP to develop the grid connect system that is on so many house roofs today for BP to install on the roofs of the 2000 Olympic Athletes Village roofs, Brad and his team went on to install over 2700 roof tops systems here this precinct.

Additionally we have always had an involvement with a cleaner environment, working with companies for the remediation of contaminated sites. Brad was always on the look out for additional methods to produce a cleaner environment so he became involved in the Ground Source Heat pump industry, became an accredited WaterFurnace installer and a member of the International Ground Source Heat Pump Association.
