Many premium solar panels are now warranted until…2046.
Solar panel prices have recently risen… except those with 25 year product warranties.
The pandemic’s economic slowdown was severe. But it’s hard to keep humanity’s lust for stuff down, and the economy is bouncing back. The rebound caught many off guard, causing shortages and price rises across an array of industries. Solar is no exception.
Canberra Battery Test Centre just released Report #11 describing its third round of battery testing and the results.
I’ll give details below but, if you want a quick overview, I can tell you the new batteries didn’t do well. Only 2 of the 8 battery brands tested worked as they were supposed to. The rest had problems that ranged from temporary breakdowns to complete failure. [Read more…]
Last week at the COP26 in Glasgow, more than 100 nations took the Global Methane Pledge and committed to reducing emissions of this dangerous greenhouse gas 30% by 2030. It was a shining moment in history as the world’s people came together to act for the common good.
When I say “the people of the world”, I actually don’t mean all of them. [Read more…]
SA’s New Solar Sponge Tariffs Can Make Home Batteries Without Solar Panels Pay
South Australia has a lot of solar. Relative to total generation it’s well ahead of any other state.
All this solar power reduces daytime wholesale electricity prices. This is a good thing. Not only is solar energy clean, it cuts costs for homes and businesses. [Read more…]
The next new car you buy should be electric.
I’m serious about this. I’m willing to include fuel-efficient hybrids in my advice for now, but anyone who’s not in the habit of chucking laps around the Strzelecki Desert should consider an all-electric car next time they’re looking to buy a new vehicle or a pricey second hand one. [Read more…]
Last week Finn got me into hot water. He did this by referring me to a study called::
“Analysis of electricity consumption and thermal storage of domestic electric water heating systems to utilize excess PV generation”
Let me translate that from Academeze into English for you:
Are electric hot water systems any good at soaking up excess solar electricity?
Here are some of the findings: [Read more…]
Australia recently decided to buy nuclear-powered submarines as part of the AUKUS pact with the UK and United States.
Assuming it goes ahead, the first sub may be ready around 2040. But while our submarines may have nuclear reactors, our power stations never will. [Read more…]
Yes, You Can Go Off-Grid With A $10,000 Battery — But I Don’t Recommend It
If you’re sick and tired of paying a supply charge to connect your solar home to the grid, then I have good news. You can now go off-grid with a battery system for around $10,000.
The bad news is, I don’t recommend it at all. [Read more…]
Last week the Clean Energy Regulator held an online information session titled, “Update on the Integrity Review of the Rooftop Solar PV Sector.” It outlined major changes aimed at kicking crap solar installers out of the industry. [Read more…]
You may have noticed the US President is looking less orange these days. Now that “sleepy” Joe Biden is in the White House’s egg-shaped office, American climate change policy is moving in the right direction. [Read more…]
