Company Profile


We have been established for almost twenty years, formerly known as E Koller Electrical Contractors where we serviced the Illawarra, Southern Highlands and Shoalhaven areas. We have worked on residential and commercial enterprises including high rise developments. 

As the business grew we moved slowly into the solar market eventually changing our name to Pro1 Solar and Electrical Services.We now deal only in the energy saving market. We only install solar systems /meter box upgrades and Led Downlights for our customers. Our aim is to reduce your electricity bill to zero.

We are located at Falls Creek (South Nowra) on the South Coast and Coledale in the Illawarra. 

All our products are backed by the manufactures warranty and we give a ten year warranty on our workmanship. We do not do projects out of our areas as  we believe if you live in the local area it is more viable to service our systems. You can have peace of mind that we are a local company and can attend to rectify/replace any part of the system should they go wrong. The procedure is simple just ring or email us. We will do the rest at no charge. We don't just service the area we live here.
