I'm in the market for 4x300+W solar panels with specs that match/is close to vmp: 36.6V, voc : 44.8V. Any good prices anywhere? Jhb based.
Edit: I wonder what panels these guys sell : http://epssolar.co.za/pages/panels.aspx. Found this article on these ECCO panels seems they are bs panels. http://www.ee.co.za/article/suspect-solar-panels-stunt-growth-community-creche.html

Are you still looking for 300W panels?
I can get you some @ R7.60/watt, thus R2280 per 300W panel. Collection from our warehouse in JHB or Cape Town

It's an Enersol 300W panel, with the following features:
I have 25W panels at R1938 as well:

Vtc is a little on the high side on those panels - you really want something better/lower for our hot sunny environment.
At 0.5%/c (over 25c), you'll be losing up to 15% or more output on an average sunny day here depending where you are located.
Its not terrible, but you can definitely get better panels.
eg STC of 0.5%
Panel at 65c (easily done here).
65 - 25c = 40c
40c x 0.5% = 20% power output losses per panel, (so a 300w panel = 240w actual output on a sunny day).
Don't forget to put this into your system calculations.
That said, panels are the cheapest part of a system, if it bothers you, just buy more...
