At my favorite electronic surplus discounter, I have ordered 6 pieces of 19v/5A laptop power supplies, and also 6 halogen 55W H3 headlamps.
The total bill was about $35.
Every power supply in series with a halogen 55W H3 headlamp simulates very closely a 100W 18VMPPT solar panel.
Since the power supplies are galvanically isolated, I can put the outputs in every parallel series combination.
So I will be able to simulate many PV situations, even at night and during the crappy winter weather in northern Germany.
