3 Phase Solar Wars : The Menace of Phantom Imports.

May the (electromotive) force be with you!

 

I’m thinking of writing a screenplay. The movie’s name is “3-Phase Solar Wars : The Phantom Imports”. Here’s the opening scene:

“Quite soon in the future, in a suburb not very far away….

 

It is a period of civil war. Solar owners, striking from over a million rooftops, have won their first victory against the evil Electricity Empire.

 

During the battle, these plucky rebel homeowners managed to get their electricity bills down so low that they are on the cusp of destroying an entire electricity retail industry.

 

But now the Empire’s sinister agents have a plan:

Genius Or Bonkers? US solar company glueing solar to roofs to reduce installation costs.

Innovation in solar never ceases to amaze me. But I can’t decide if this particular innovation is genius or totally nuts.

US solar panel manufacturer Lumeta Solar have announced a new 175W solar panel design that is super thin, with no frame, a junction box on top instead of underneath, and get this: double sided sticky tape on the back.  The idea is that you simply peel the backing off the tape and stick the panel to the roof.

Enphase Micro Inverters Claim Higher Profits, Lower Costs

A recent survey showed of 32 residential solar installers over a two-month period showed that micro inverters were able to reduce soft costs compared to conventional central inverters. In fact, major micro inverter manufacturer, Enphase claim that installation using their TRUEAC modules have can reduce labor costs by up to 48%!

They also claim that installers in the US had to walk away from 1 out of 4 jobs if they weren’t using micro inverters (which are easier to install on difficult roofs).  I find this really hard to believe, but if it’s true I can only put it down to the prevalence of online quoting without a site visit over in the USA.  You really do need a site visit if you want a high performing solar system properly designed for your roof.  You simply can’t do it with Google maps (even with micro inverters)!
