Jeremy and Kate live in a Pettit+Sevitt home, designed by Sydney architect Ken Woolley near the start of his career. Their house is on a steep block, surrounded by mature trees. The trees have grown over the years turning harbour views into harbour glimpses, but they like it that way.
We believe that the fact there are trees increases the value of property in Mosman. In a climate change world it reduces temperatures and gives us oxygen and all sorts of good things.
The natural environment has always been important to Kate and Jeremy. They were both involved in the long campaign in the 80s and 90s to prevent Sydney Harbour’s foreshores from being developed, which led to the establishment of the Sydney Harbour Federation Trust in 2001.
The family installed a small rooftop solar system back in 2009 to take advantage of the 60c feed-in tariff. But ten years on, their solar feed-in had dwindled to almost nothing and mature trees put the panels in partial shade for much of the day. Kate and Jeremy wanted a more efficient system but they were determined to keep the trees. After talking to Zero Emissions Sydney North they obtained quotes for a new system and chose Solarpro to install it.
A solution for shady sites
Solarpro recommended installing a 3.7 kW system comprising 10 LG Mono XL panels, using a Solaredge inverter, which could make the most of their tree-shaded, west-facing split level roof. The installation took half a day and cost $5,433, plus $650 for their old panels to be recycled. The new system generates nearly twice as much electricity.
The financial benefits of solar are not Jeremy and Kate’s key motivation, but their new system is already making an impact on their power bills.
Where does their motivation come from?
“From the soles of our boots”, says Kate, “to our heart and souls. We started bush regenerating and got gradually more and more concerned about the environment. We want to do what we can.”
