What are the power requirements and current consumption (in amps and kW) needed to maintain level flight “zero”? Please share details such as takeoff weight, paraglider type, and size.
Thanks,
Radek

thanks Marius 
it’s a great result, In my case 135kg, 3B 140cm E-Props, Dudek Snake 20, Ozone Speedster 26, Dudek V-King 23, for all of them almost the same value: 6,5kW (60-70A) - pretty high 
- 3kWh - 30min of flying
With which system? Only SP140? Or others, too?
It’s a SP140 setup

With my Viper 6–22m and my weight of 185 lbs, I see a cruise power of around 3.3–3.6 kW and get 70–80 minute flights just flying normally (not trying to be super efficient, and often with trims halfway out).

I need to understand why my power consumption is twice as high as yours 
Wings do make a big impact on efficiency, especially if they are older versions. However, there are other simple things to check, like making sure the leading edge of your prop is clean and smooth. Bugs, grass, and other debris can cause more air separation and drag.
Weight also matters, especially if you’re near the higher end of the weight range for the wing. So in your case, if your all-up weight is around 300 lbs and you’re flying a 20m Snake, then I would expect that to result in slightly higher power consumption.
Thrust angle can make a difference as well. It’s best to have a 5–15 degree upward thrust angle. I’ve noticed that with a level thrust angle, efficiency can suffer. I’d like to do some formal testing on this, I think it would be cool.

I did a test this weekend and found myself able to maintain level flight at 1.8-2.1kWh as seen in this video with the following setup:
- 105kg All up weight
- 22.5m2 Ozone Mojo6
- v2.5 4.8kWh battery
- 140 bi-blade prop
I never just fly level though so for more detail, here’s a graph of my flight time vs power consumption across 20 flights with the V2.5 battery, showing that my average power use mid flight is 3.3kW.

Dudek Universal 1.1 25.5, 115 kg (which is at the upper end for the glider) with the 4 kW/h battery, and the 140 tri-blade, I see cruise at about 5 kW. With the smaller battery, it is more like 4 kW – which is due both to the weight and perhaps the more vertical thrust angle, since I hang slightly differently.
One thing I’ve noticed is that conditions tangibly affect cruise power – not just bumps and thermals (though maybe I underestimate thermals). Some days I gain altitude at 3.5 kW with the heavy battery. Some days I lose altitude at 6 with the light battery.

I’m flying Nova Ion 4S, I cruise level at about 4.5kwh, pilot weight of 180lbs, 3.7kw battery pack.

I am also at 106kg all up, flying a 23M Macpara Colorado, 3 blade 140 prop, V2.5 motor and 2.5Kw battery and my level power consumption is around 3.5Kw, so I am surprised you are able to get 1.8-2.1!
