Home/office renewable energy

A case study

What does a renewable energy system cost?

The purchase of a renewable energy supply system is not for the financially faint of heart. Considering that we buy grid electricity for less than 5/kWh, our investment of over $50,000 on equipment might seem a little nutty. But this is a hobby and a household journey that we find endlessly fascinating and educational.
