Whilst pollies spent the week campaigning, Aussie researchers made the biggest breakthrough in solar efficiency in years.

Used to being marginalised during election campaigns, the renewables sector hasn’t exactly sprung to the centre of attention during the latest most important election since the last one. However there are signs that the two major parties are taking notice of the Australian electorate’s overwhelming support for a strong renewable energy policy as we dip into the election renewables news roundup for the second week.

GCL’s E-KwBe Battery, Or Something Similar, Will Change The World

May 17, 2016 2024-06-04T15:38:47 by 22 Comments
gcl e-kwbe battery

The GCL E-Kwbe battery may be unpronounceable – but it may also save the world. Kind of.

GCL, a large Chinese company, has unveiled a new lithium-ion energy storage system at a price point that some consider to be shocking. Called the EKwBe, it has a seven year warranty, a ten year expected lifespan, and comes in two varieties. A 2.5 kilowatt-hour system that wholesales excluding GST for $1,499 and a larger 5.6 kilowatt-hour system that wholesales for $2,999.  This is the lowest price that has been offered for any comparable energy storage system and I believe that it, or something similar, has the potential to change the world.

Update: 1st December 20016.  The GCL EKWBE battery currently appears to be retailing for around $3,600 inc GST.  This doesn’t give it a cost per warranted kilowatt-hour as low as the announced Tesla Powerwall 2, but it will be interesting to see if GCL will cut its price further in response once the Powerwall 2 is actually available for installation.

Revealed: Ausgrid’s Devious Strategy To Keep Solar Customers Confused

ausgrid complaints

Want to ask Ausgrid what the rules are for connecting solar? Then be prepared to enter their infinite loop of hell.

In order to help out people who are considering installing rooftop solar in Sydney, I took it upon myself to find out what people need to know if they want to install a system in the Ausgrid Electricity Network area. I did it for the benefit of humanity. Well, specifically for the benefit of people in the eastern half of Sydney, but if it results in more clean solar electricity being generated, then it will benefit all humanity. [Read more…]

Perovskite solar cells in commercial production just around the corner says report

May 2, 2016 2024-10-04T07:02:13 by 1 Comment
Perovskite

An unassuming lump of perovskite. “The fastest improving solar cell technology there has ever been.”

We’ve previously covered the novelty of perovskites as a potential game changer for solar cell cost and efficiency, and also asked why, with such a name, they haven’t as yet debuted in the latest James Bond blockbuster. But perovskite solar cells in commercial production as the “Next Big Thing” in solar cell technology? Surely that’s a long, long way off? [Read more…]

Think tank predicts end of fossil fuel in a decade

No fossil fuels from 2026?

Most supporters of the clean energy revolution have never wavered in their belief that renewables will be the dominant energy source of the future. The only question is how long before we wean ourselves off fossil fuels.

Now a think tank based in the United Kingdom has had a stab at answering this $64 question by predicting that fossil fuels could be phased out almost completely over the next decade.

The Sussex Energy Group, based at the University of Sussex, has said that a co-ordinated effort could see the switch to clean energy brought in much earlier than previously thought. [Read more…]

Enphase’s Cunning Plan: Make Micro Inverters Cheaper than String Inverters.

April 14, 2016 2016-05-30T14:05:55 by 17 Comments

enphase costs: half price by 2017When it comes to Australian solar installations, conventional string inverters tower over the competition like a current converting colossus. But microinverters, which are tiny in both physical size and market share, are shaping up to beat string inverters on both price and reliability. Enphase, the world’s largest producer of microinverters, plans to beat conventional inverters on price within two years. If they meet their goal of cutting micro inverter costs in half, it will change the way Australians install solar power. [Read more…]

The race is on as Panasonic snatches lead as most efficient solar panel

panasonic most efficient panel

Panasonic snatch the title for most efficient panel from Sunpower.

Well that didn’t take long! No sooner had we published our article on SunPower grabbing the unofficial prize of most efficient solar panel for commercial use, than Japanese manufacturer Panasonic surprises with a late sprint to the line.

The Japanese manufacturer has now jumped into the lead in the solar conversion Premier League with not one but two records. The new record, which was verified by the Japanese government-funded National Institute of Advanced Industrial Science and Technology, is an eye-catching photovoltaic module conversion efficiency of 23.8 percent. This leaves SunPower’s previous record in the dust by a full percentage point. [Read more…]

Trina Solar Panel Efficiencies Keep On Rising,

Trina Solar panels look set for a big 2016 with news that the company has achieved yet another solar cell efficiency record.

Fresh from trouncing its previous record for efficiency for a p-type polycrystalline silicon solar cell, Trina Solar announced last week they had achieved an efficiency of 22.13 percent for a 156 x 156mm² solar cell for a mono-crystalline silicon (c-Si) solar cell. This beats the company’s previous record of 21.40 percent, set in November 2014. [Read more…]

Do Electrolytic Capacitors Cripple Microinverter Reliability?

November 12, 2015 2017-04-19T14:11:28 by 15 Comments

Part 1 of an interview with Enphase VP of Quality & Reliability: Ciaran Fox

In my experience solar installers either really love microinverters, or are incredibly wary of them. There seems to be very little middle ground.

Those who love them talk about their ease of installation, increased power output, flexibility of panel layout, panel level monitoring and shade performance.

Those who are wary of them generally worry about their reliability.

A microinverter is a box of sophisticated electronics that sits on your roof (under each solar panel). In Australia your roof gets hot! And if a microinverter fails, replacing it means climbing on the roof and removing the panel. So installers’ concerns are understandable.

an Enphase microinverter

A microinverter. You generally use one per solar panel instead of a single large central inverter. They are about as big as an iPad mini

To get some authoritative answers, I asked installers that I know to send me their toughest questions about microinverter reliability.

I then put those questions to Ciaran Fox who is the Vice President of Quality & Reliability at the world’s biggest microinverter manufacturer, Enphase. [Read more…]

We ask five experts: Will battery storage change the way we live?

September 23, 2015 2017-10-24T13:52:48 by 4 Comments

In the first of a series from SolarQuotes, we ask five eminent experts in the clean energy field to discuss four questions on a selected topic. This month we’ve selected “battery storage” as the launching pad for some fascinating discussion and advice.

Solar and battery storage has been one of the clean energy talking points of 2015 following the dramatic unveiling of the Powerwall by Tesla’s Elon Musk. However as we’ve seen, the Powerwall isn’t the only option out there in the marketplace and the best battery storage option will differ depending on your situation whether on-grid, off-grid or hybrid solar.

With this in mind we’ve asked our experts what these solar battery storage breakthroughs mean for Australian households and small businesses and what the future holds for energy independence. [Read more…]
