Solar panels on the roof

While on the road, this caught my eye.
14 solar panels and a solar hot water panel.



I wonder the wind turbine is a workable unit.

I got curious and did a search on what this building or company is about.
It sells recycle t-shirt, skirts, organic cotton bags, bamboo made materials.
It also sells solar cells like the one in the photo, energy saving kits, and even an organic food stall.

It looks interesting, I shall visit that shop one day.



I wonder if those of us living on public housing, can hot water panels be installed on the shared roof. That would save us lots of electricity in the long run.
