Battery Market Booming
The chart above shows the ESS attachment rate (actually the ratio of ESS-to-PV systems). In May, preliminary data shows there were 1.4 battery systems sold for every PV system. That’s massive!
In recent years, annual rooftop solar installations have declined in number, been consistent in capacity (kW), but revenue has declined considerably. People’s interest in batteries may also boost flagging PV sales, providing a shot in the arm for panel manufacturers.
But, according to our initial data, the battery boom won’t uplift panel manufacturer volumes, at least not yet. As the chart below reveals, retrofit-batteries are growing faster than PV+ESS systems, as solar owners take advantage of the rebate. Retailers are focussing on battery sales, because that’s that’s what’s causing the phones to ring, and because batteries generate more profit than panels.
