About OG Trade Services

OG Trade Services, the official importer of Neovolt battery systems, is a South Australia-based company with a strong national presence and a reputation for excellence in renewable energy solutions. Established in 2013, OG Trade Services—also known as Say Yes Solar—has spent over a decade designing and installing high-performance solar energy systems across South Australia and beyond.

Our mission is to provide comprehensive, professional, and fully integrated energy solutions that are tailored to the specific needs of every customer. We are committed to quality, innovation, and customer satisfaction, and we pride ourselves on delivering solutions that drive long-term energy savings and sustainability.

In 2018, in response to growing market demand, we expanded our service portfolio to include air conditioning, heat pumps, and home improvement solutions. This strategic diversification has allowed us to evolve into a trusted, multi-disciplinary provider serving both the renewable energy and home enhancement sectors.

With a forward-thinking approach and a dedication to superior service, OG Trade Services continues to lead the way in helping Australian homes and businesses transition to smarter, cleaner, and more efficient energy use.
