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…]

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.

Phono Introduces MWT Panels:  A Dotty Idea For Improving Efficiency

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.

Don’t Buy Second Hand Solar For Your Home

You’ll Pay A High Price For Second Hand Solar Equipment

“Psssssst!  Wanna buy some slightly used solar panels?  They fell off the back of a truck.  Or possibly off the back of a roof.  Maybe they even fell off the back of a roof of a truck.  We just don’t know.  But what I do know is they are tier one panels in great condition – they didn’t fall far – and they’re cheap, so if you are looking to install rooftop solar you’d be a fool not to buy them, right?”

Wrong. [Read more…]

Scheme To Donate Solar To The Sydney Opera House Is A Boondoggle

Sydney Opera House In Sustainability Scam Shocker! Photo Credit: Finn

This morning the Australian Financial Review reported on how the Sydney Opera House and Energy Australia, and apparently even the CSIRO, are teaming up to create a solar energy trading scheme that, on the face of it, is completely useless.  But, once you think it through, it clearly makes the world a worse place.
