Peer Reviewed Study: Grid Connect Solar Helps Environment But Batteries Harm It

academic in ivory tower

A paper published in ‘Nature’ has agreed with Ronald’s back of an envelope conclusions from last year: at the moment, most grid connected storage harms the environment.

Almost a year ago I wrote an article about how on-grid home battery storage does not help the environment but instead harms it by increasing greenhouse gas emissions and other types of pollution. I am raising this topic again, hoisting it above my head, and waving it around, because a scientific paper published in the journal Nature vindicates my position. [Read more…]

Solar Panel Torture Testing: Jinko & Trina Do Well

DNV-GL reliability scorecard

Now you know what the those DNV-GL engineers *really* get up to in their secret European HQ…

DNV-GL’s PV Module Reliability Scorecard Report for 2017 is out1 and gives some fascinating results.  You can follow that long link in the previous sentence to download your own copy of the report, but for your benefit, I’ve included my own unique analysis below, where I will give my interpretation of the results in 2,000 words or less.

Or possibly more.  I’ve only just started writing so don’t really know just how many words I’ll require, but if it looks like I’ll go over my self-imposed limit I can just leaveoutsomespaces, so it’s not really a problem. [Read more…]

What is a PERC Solar Panel?

perc solar panel

34 years after it was invented ‘PERC’ is now a big deal in solar panel technology. But what the hell is it?

Update 16th April 2019:  Many PERC panels have suffered from LeTID deterioration problems since this article was written.  This article here goes into the problem and this article on the MC Electrical blog covers it in detail and gives information on which PERC panels are resistant to LeTID.

Solar panel manufacturers crave efficiency.  I’m not talking about the labour efficiencies they receive from building new production lines that are robot-heavy and people-light, although they like those too. [Read more…]

Can An Installer Change The Quoted Price Of My Solar System?

stc price

The STC price has plummeted and pushed the price of solar up. What should you do if you’ve already accepted a quote and the installer wants to increase the price?

I’m going to ask you to imagine preparing to buy a rooftop solar system.  I want you to see yourself working hard, saving your money, doing your research, and getting yourself some quotes.  After careful consideration, you decide upon an installer, sign the contract, and transfer a 10% deposit to them.  At that point you would be looking forward to saving money on your electricity bills and doing your bit to help the environment.

Now imagine how you’d feel if, before the day of the installation, the installer contacts you and says the price has gone up and you now have to pay $1,000 extra.

I imagine you wouldn’t be very happy about it. [Read more…]

SolarEdge HD Wave Review:  The World’s Smallest And Most Efficient String Inverter

ronald and a hdwave

Today Ronald examines the SolarEdge HD Wave inverter. It’s small. But not that small.

It’s An Itsy Bitsy, Teeny Weeny, SolarEdge, HD Wave String Inverter…

SolarEdge, an Israeli company, has produced the HD Wave — the world’s smallest string inverter.  By size, this little cracker takes more DC than any inverter out there.  Not only that, but it grabs DC, uses its funky HD wave technology on it, and spurts out the AC our homes use with greater efficiency than any thing else on the market.  And it’s now available in Australia, starting from a couple of weeks ago.

Solar Panel Clamping Zones: Are Your Panels Mounted Correctly?

That clamp is not in the zone! After reading this post you will know what that means. (Photo credit: Matt Hines – definitely not one of his installs)

There is one main way solar panels are attached to roofs in Australia and I’m hoping you won’t be surprised to learn it’s not glue.  If you’ve got panels, they are almost certainly fastened to your roof with clamps and held tight in the loving embrace of metal brackets. [Read more…]

Chinese Company ‘Tesla New Energy’ Steals Tesla’s Name And Logo

The ‘Tesla New Energy’ website yesterday.

Many people are aware Tesla is planning to produce solar tiles, but not so many know the company is also has plans to sell conventional solar panels.  According to one report, Tesla is going to follow the novel approach of producing them inside a buffalo in New York.  Production is scheduled to begin within two months and the panels will only be available from Tesla.

The panels are not featured on Tesla’s Australian site and I currently have no information on when or if they will be available here.  But if you do enough searching on the internet or, more likely, receive some spam from them as I did, you may think you can order some of these panels from the Tesla New Energy factory in China.

Solar For Renters? Landlords & Tenants Share The Benefits with ‘Matter’

rental property without solar

Have you ever noticed that rental properties almost never have solar?

Australia has the lowest cost rooftop solar in the world, plenty of sunshine, and because we are heading towards having the most expensive pre-tax grid electricity in the world, solar is a must have for almost anyone who owns a roof.

But over the past 11 years Australian home ownership has fallen from 70% to around 66% and since it costs over a million bucks to buy a butterbox in Sydney, this figure isn’t likely to improve any time soon.  This means one-third of the Australian population is locked out of owning rooftop solar.
