Kings Solar Panels?

Siringo
Good luck with warranty claims/issues with all but very well known solar suppliers, ie house panels, and some well respected companies of course. But then again, with those you won't be claiming because it is accurate and as expected, give or take a bit.
193W for a 110W panel? 75% more is good value indeed. Solar panels are stated as a size but ONLY the solar cell area actually generates any power, the border and frame outside the ACTUAL panel cells is there for good looks and support. I have a folding ALDI panel 120w stated which uses two 850 x 520 panels, however, the solar cell dimensions of each panel is 775 x 470 which totals, not 0.884sqm as it reads but 0.72 sqm, which can never generate 120 watts unless the efficiency is remarkably high. They work, but expect less than quoted in specs and claims. I bought a fixed, not folding panel, a while ago and the stated output was not high. The 80w stated was slightly more current than a well known brand of 60 watts. Both tested side by side for SC current.

That equation is only a ballpark rough guess without knowing the real conversion efficiency. Use 16-17% and dont include the borders of the panels.
The tragedy of this equation is it actually tells you nothing about the quality of the panel. Cheap stuff doesn't last that long, the proper brands like LG, Panasonic etc give long output warranties and have supperior quality but are usually all too big. All the cheap sources I have seen mostly lie about the wattage for marketing. No one ever gets anywhere near the wattage in real world due to losses. Basically if you buy solar and they are portable expect to replace them pretty soon within say 3-7years. Maybe alot sooner if flexible type.

I can confirm that the Enerdrive panels are rated conservatively. I put them on a mobile home about ten years ago after much research and they were still behaving and looked as good as new when I sold it last year. I put the same brand on a new truck based camper two years ago and have seen the ammeters reach and just exceed the rated amps on several occasions even though they are mounted flat and the time was well before true midday! Clear blue sky and a cold wind is the trick - and you need an air gap under them!

They have high voltage (about 40v) models that we use to feed an MPPT controller so that it begins to pick up a useful charge from early in the morning when other panels still cannot produce adequate voltage. Jaycar have beaut analog ammeters to put in line and get a good feel for how things are going. You can prise off the clear plastic covers and mark them with a good band to aim for. Ours are hard to get to and clean so by having several I can see when it is time to get up and clean them (as the needles are not in sync.).

Best wishes,

Thanks everyone for the help.

I have had a 100W Kings fixed solar panel for over a year, cost me $110 delivered. Puts out about 5.5A in full sun. No complaints, so far so good.

Also had 2x 120W folding "Rich" branded solar panels on my camper roof, they appear to be 120W on the area/solar formula. They are mounted flat and when the sun is directly above them I have seen 12.5A output. Had them for 8 years and they were pretty cheap back then, about $160 each from memory.

I have noticed that while cheap solar panels aren't as efficient as "good" ones they seems to last just as long. My mates have had similar experiences.
