Peter Hannam quoted me in RenewEconomy on Friday, saying I expect there are hundreds of thousands of solar and battery systems out there that aren’t optimally installed or configured, some of them carrying real potential for dangerous outcomes.

Neovolt have been threatened with de-listing because their CEC approval paperwork isn’t in order. I find this curious because when I’ve asked about similar approval paperwork in the past concerning Growatt products, they weren’t de-listed. And the CEC refused to answer our questions.

Electric cars have notched up their biggest Australian milestone yet. In August, they outsold petrol cars for the first time, taking almost a quarter of all new vehicle sales. For households, that also means more transport energy is shifting from the petrol bowser to the electricity meter.

We’ve seen a big change in the solar industry recently. With batteries becoming standard, everyone is getting backup. The problem is that poor design and sales misunderstandings are leaving people, especially three-phase customers, with a total oxymoron: unreliable backup power.

Carefully trickle-charging your EV with surplus solar instead of buying electricity from the grid sounds like the perfect way to charge. But there’s an uncomfortable truth: slow charging can waste considerably more energy than charging at higher power with a home charger. Spoiler alert: that doesn’t mean you should stop charging from solar. Cheap electricity […]

Everyone buying solar wants lower bills, but adding expensive batteries should be more about a reliable supply than straight-up bean-counting. The solar industry has, for a long time, glossed over a pretty basic point in battery-backed systems, so strap in while we explain the difference between series and parallel-connected supplies, and why it matters.

Most of us want to believe the best in people. If your solar installer says they’re waiting on stock, you’ll probably accept it. If they ask for a few more weeks, you’ll give them a few more weeks. But when does patience stop being reasonable? That’s the question NSW homeowner Mark Barnes eventually found himself […]

A fortnight ago, 7.30 aired an investigation into Solar Power Nation, a retailer the ABC reports is under investigation by authorities in Queensland, NSW and South Australia after hundreds of complaints. One customer, Amin Khorram, paid $13,000 for a battery system. Only one of the two inverters was installed, so he got 5 kW of […]
