Are You Being Served

Two of our subsidiary wineries had the solar systems installed through Peter O’Leary at P4B Solar. For both cases, we have had very positive experiences, from feasibility analysis, to planning, to installation.

We find the service provided by Peter very professional and reliable. They have assisted and supported us from initial enquiry stage all the way through to installation, and have followed up and visited us on various occasions after installation to ensure the systems are properly operating and maintained.

I would highly recommend Peter as a consultant and service provider for a commercial solar system.
