We just had a 30kw battery and solar panels installed in the Hawkesbury. Brad the sales consultant really looked after us and gave us good advice/recommendations to ensure we didn’t have a power bill any more. Nathan and his team carried out the installation at a very high standard. Extremely happy with the entire experience and would strongly recommend to friends and family.

Darren Massey

I had an excellent experience with ND Solar Group. The quote was very competitive, absolutely worth it for the quality of work and level of professionalism you receive.

Nathan and his team linked my old 6.5kW solar system into an additional 8kW system plus a 30kW battery, all running through one seamless app that lets me monitor everything easily. The workmanship was amazing, and the neatness and tidiness of Nathan and his entire crew really stood out. Everything was done to a high standard and left spotless afterward.
