A very interesting panel from Renogy

Panel tec is continually improving, our local council have been fitting solar to all of their properties in the last few month. Firstly it labels the few council properties left! I was initially surprised that it was worth putting four panels on a small one bed sheltered housing bungalow, then I realised they had put eight on the roof, 4 south facing and 4 NORTH facing.

Strange that as the sun risses in the east and sets in the west, even the Irish know that. 😂
 
Low light solar panels are becoming quite common, obviously your better off with South Facing un shaded panels, but that’s not always possible.

My panels are in a perfect position, all south facing, no shade. But next doors roofs face East and West (again no shading) so they have 14 panels on each side and it works, ok not as well as mine and it costs a lot more, but work it does.
 
Front of my hovel faces east and back west, so i would require 2 sets of panels, and i would have to live long after my 3 score years and ten to get my monies worth out of the instalation price.
 
I have fitted 18kw of the n-type panels to my workshop / house with 18kw battery back up. So far they have produced 11.2 MW

These Renogy panels use the new BS method of advertising claiming 25% efficiency in the adverts pictures but when you read the specs and small print they are tested to the current test standard at just over 20%

At this moment in time there is not an agreed standard independent test for certain types of conditions e.g. shading or panels like bifacials so sellers can and are getting very creative with their claims.

Caveat emptor and all that!

Lets not forget as well Steve, aside from the monetary aspect when everybody else is struggling during power cuts etc. Sam and Kev don't even flinch.

Sometimes some things are just nice to have and if you can afford it why not?

I have a bodge solution to that - the lorry on the drive and a cable with two male plugs on it. Some caution required in using 🤣🤣🤣

Just use a safe casmper blue plug at both ends, not forgetting a 3 way switch between house meter and your fuse box, this is my next adventure. :unsure:
 
Seems appropriate to post this here, I had/have a spare 85w panel, one of two I bought from a facts member, and it was going down to Merlins to be fitted but I wanted to test it first, I was also testing a DC clamp meter Merlin suggested (link below), time and date below, so not scortching, but full sun south facing 2 miles from North Yorkshire.

Beware when you buy it if you want one, the price fluctuates a bit I paid £27.19p

He's so far generated to the order of £3000.

@Scotia how long has it been in mate? 18 kW is nice 👍

It went live on the shortest day, which was a good time as we saw an increase each week. We have had exceptionally great weather this year though which was a bonus allowing us to run the 3kw element for water 5hrs a day most days after the battery was full.
 
Solar panels have got better over the years, but not by much.
Yes, 23% is indeed 15% more efficient than 20% but if the panels are 40% more expensive, only the seller is making a gain.
You'd be better adding one more panel to the array.

The 3 way switch is the correct, but expensive, way.
