Directly using PV panel (without batteries/inverter)

[gfry2267]

fun

maybe my learning curve is slow- thats ok
bought a sun king 250w inverter
bought an ac disconnect box and 4awg wire
its all connected and waiting for sun
trying to cut my losses


are ecoworthy panels ****?
i can can only get 5+ amps in parallel/ 2 100 watt panels

thanks for reading

Most 100W panels can put out approx. 5A max. each (check the Isc on specs), so in parallel you normally would expect 10A, however that max is only near solar noon with proper sun/panel angle, temp, etc. Are you using a charge controller? If so that will impact the total throughput greatly depending on the specific CC.

i tested today and got around 6 amps at around 15 v - around 100w in parallel-2 100 watt panels- so you are correct. i must not be at optimal setup. no charge controller or batteries.


i am running directly to plug and play 250w grid imeshbean tie inverter/ through an ac disconnect box. lots of wire, i expect loss. at max today kilawatt showed max 90+ watts / .22 kwh.

Thanks for your response.

Go Pack!!

Was the 6A at 15V reading direct from the panel pigtail (everything else disconnected) or with system hooked up to the GTI?

it was connected to the gti and then a kilawatt meter plugged into the ac wall socket. so maybe 6a 15v wasn't too bad given all the potential loss in wiring and I am sure I didn't have the panels optimally pointed. But they were in some good direct sun.Thanks for the reply. I will have to play some more. Maybe I will switch energy and finances to making a bigger solar can collector and use the panels for fans.
