I was slack jawed when one participant shared his revolutionary idea on solving the old “Grid tie” vs “Battery storage” dilemma. I’d always though that it was really one or the other given the feed in tariff or mircoFIT, what I didn’t know is that you can have both! Apparently when Nortel went belly up he bought a whack of deep cycle batteries and now charges his batteries with his solar panels and sell the power back to the utility only during peak hours. A brilliant idea. Perhaps if all grid tied PV systems stored and supplied only on peak, it might benefit society more by not having to generate on peak. You learn something everyday!

All the best to the participants taking the course, it was a pleasure to meet you and very encouraging to see more people who are committed to efficiency!
