Some people are getting their knickers in a twist over whether REC solar panels are European or Asian.

I’ve had a request to clear up the question of whether REC is a European or Asian company. The confusion arises because although the company was founded in Norway and has its headquarters there, it manufactures REC solar panels in Singapore and is owned by a Chinese corporation.

I have looked into this topic exhaustively and I can state the answer to the question of whether REC is European or Asian is — Yes.

Yes — it is European or Asian. [Read more…]

Solar Panel Optimisation is an extra feature you can pay for when buying solar that optimises the power output from each panel independently. [Read more…]

Don’t let a half-cut solar installer install your half-cut (AKA split-cell) solar panels.

Silicon solar cells of the type now used for almost every residential solar installation in Australia have been around for a long time.  They are 64 years old.  This makes them the same age as nuclear power generation.  They’ve come a long way since they were first made at Bell Labs in the United States.  Originally they were only able to convert around 6% of the energy in sunlight into electrical energy but now the most efficient solar panels on the market manage 22%.

Unfortunately, the days of large improvements in efficiency have long been over.  Now we only see small incremental improvements and one of these in use that will be much more common in the future are panels that use half-cut solar cells. These panels are known as both half-cut and split-cell solar panels. [Read more…]

It’s only two months now since I wrote an article telling everyone in the world the product warranty for LG Solar’s NeON 2 panel was being extended from 12 years to 15.  But if you were looking forward to to getting some NeON 2 solar panels and enjoying that sweet 15 year warranty, I’m afraid you’re out of luck because it’s no longer available.  Instead you’ll just have to enjoy a massive 25 year product warranty as it has been extended by another 10 years.

Bad news for fans of cheap panel level optimisation. Jinko MX solar panels are not coming to Australia.

Last Tuesday I went to Sydney to attend the Smart Energy Conference & Exhibition.  I learned many things, one being that Jinko Maxim panels that use use cell string optimization — described in  this article — will not be sold in Australia because they were unable to stop them interfering with television reception.

LG’s more affordable panel range, the NeON2, has gone from a 12 to 15 year product warranty.

I like high quality panels.  I really do.  If a panel is well made, reliable, and comes with a full replacement warranty that’s something I appreciate.  Seeing panels go up on roofs that have a decent chance of lasting longer than I will makes me feel positive about the future.  Obviously not my future, but the future in general.

A major provider of high quality panels in Australia is South Korea’s LG Solar.  I only have good things to say about them.

No wait, that’s not true. [Read more…]

What the hell is a Black Max solar panel?

I recently wrote an article on black solar panels and included pictures of sexy black ones from SunPower and LG Solar.  What I didn’t do was mention Seraphim Black Max panels.  This is something I probably should have done, as we have received some inquiries about ‘Blackmax panels’.

Fortunately I wasn’t asked directly because all I could have said about them a few days ago was, “They are black solar panels made by Seraphim that are called Max.” [Read more…]
