The Solar Spectrum And Why “UV Solar Panels” Are A Con Job

rainbow power company

We are getting reports of people paying through the nose for 5kW of “UV Solar Panels” from fast talking salespeople. Paying more for “UV Panels” is about as sensible as buying rainbow powered panels from a leprechaun.

The sun is a very large, naturally occurring, fusion reactor in the sky.

It constantly releases a vast amount of energy.  Even by the standards of sky fusion reactors it’s pretty powerful and outshines at least 90% of the stars out there. [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…]


  1. Actually, it’s been out for a couple of months, but as I spent most of June honing my sleeping skills I’m only writing about it now.

What is a 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?

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…]

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.

P-Type And N-Type Solar Cells’ Excellent Electron Adventure

p-type and n-type

Do you know the difference between a P-Type and N-Type solar cell, duuuuuude?

When it comes to material for making solar cells, silicon is the most bodacious of all the elements.  Its market share is an excellent circa 97%1.  If you want solar PV, there is next to no choice other than silicon.  However, there is more than one type of silicon cell, which is fortunate for people who enjoy faffing about when deciding what to buy.

  1. Back in 1995, cadmium telluride thin film solar was 30% of the market, but apparently its makers didn’t get the message only the cells were supposed to be thin and not sales, margins, market share, and chances of staying in business.

Phono Introduces MWT Panels:  A Dotty Idea For Improving Efficiency

robin and a phono MWT solar panel

Phono Solar have only gone and drilled holes in their new solar panels…

If you want a solar cell to produce electricity then it’s important to let the sunshine in.  Specifically, into the solar cell.  Not letting the sunshine in is a bad idea.  Despite how very important this is, most solar cell manufacturers place a fine metal wire grid on top of their cells that blocks around 5% to 6% of sunlight falling on them, for no other reason than they don’t work without it.  It appears the metal grid is necessary to make electrical contacts required for current to flow.
