LeTID: Limited in new PERC panels from reputable manufacturers and probably not a disaster for old ones.
Fourteen months ago I wrote about a type of solar panel degradation called LeTID. This is short for Light and elevated Temperature Induced Deterioration. It’s also Norwegian for “laugh time” which is what I think they called the Joker movie over there. [Read more…]
If you want to sell residential solar in Victoria or batteries in SA, CEC Approved Solar Retailer membership is de-facto mandatory.
The Australian Competition And Consumer Commission — ACCC for short — is seeking submissions on whether or not the Clean Energy Council’s Approved Solar Retailer scheme should be renewed. [Read more…]
Astronergy, Canadian, Longi, & REC Do Well but PID Still A Problem
PV Evolution Labs, or PVEL for short, has published their 2020 PV Module Reliability Scorecard. This annual report reveals the Top Performers from their latest round of solar panel testing. The information given is limited. We’re only told which panels suffered little deterioration from testing. PVEL do not reveal which performed poorly. They do not even reveal all the panels that were tested. But it’s still useful to know which did well.
If you buy a solar panel that was a Top Performer in all four tests you can be confident it’s going to last for decades. [Read more…]
Honey, I shrunk the battery market
When I was a kid, the past wrote checks for the future reality couldn’t cash. I never got a flying car, let alone a jetpack, and a picture book I had promised me the 2020 Olympics would be on the moon. Well, it’s 2020 now and we don’t even have an Olympics, let alone a moon colony to hold it in. [Read more…]
COVID-19 has contributed to wholesale electricity prices cuts, which should be reflected in your power bills from July.
The coronavirus has killed more than 340,000 people worldwide and taken a big bite out of economic activity. Fortunately, Australia’s death toll has been low thanks to the effective response from medical professionals.
While we’ve gotten off lightly with regard to lives lost, there has been a sizable economic downturn. This has caused wholesale electricity prices to drop, which you should see reflected your bills from July. Unless you’re in Western Australia. [Read more…]
The SA Government commissioned a calculator for their home battery scheme. It shows that, for most homes, even subsidised solar batteries don’t add up yet. So they buried it on their website.
Finally, after one and a half years, the South Australian Home Battery scheme has added a battery calculator to their site. [Read more…]
Thanks to a deficit of trust in government, people are rightly worried when they hear that ‘the government wants to be able to switch off their solar systems’.
On the 30th of April the AEMO or — as it’s known by the long-winded — Australian Energy Market Operator, published a significant report called Renewable Integration Study 1. A few people read the summary and then wrote articles on how the grid wants to take control of people’s solar inverters; switching them on and off as they desire. [Read more…]
Planet Of The Humans: Earth Day documentary by Jeff Gibbs and promoted by Michael Moore. It’s zero stars from me in this review.
Two days ago I watched a documentary called Planet of the Humans that was released on Earth Day on April 22. It’s by Jeff Gibbs and promoted by Michael Moore, who was its executive producer. [Read more…]
If you are not allowed to export any of your solar electricity, is it still worth getting panels?
Some people in Australia can’t export solar electricity to the grid. This is because their local Distributed Network Service Provider (DNSP) has export limited their home to zero kilowatts. While this isn’t common — yet — it is a tragedy wrapped in personal economic pain. [Read more…]
How much can you save over 10 years by choosing a higher efficiency solar inverter?
A solar inverter’s efficiency determines how much solar electricity will be lost on the short journey from your solar panels to your switchboard.
The efficiency of popular Australian residential solar inverters varies from 96.5% to 98%. Higher efficiency lets a home squeeze more kilowatt-hours of generation out of its solar power system. [Read more…]
