my laptops's 40 wh battery could recharge from dead to full with the energy harvested in one hr of full sun with a 100 watt panel. A full charge might last longer than 3-4 hrs of use.
2 x 25watt lights would consume 50 watts/hr or 200 wh in 4 hrs of use.
So to restate the question, is 100 watt panel enough power for some unknown laptaop usage and 2 x unknown watt lights for 4 hrs of use. Assume all lights and laptops are the same. Unknown location, unknown time of year, unknown panel tilt, unknown wiring losses, unknown ...
Sure, give it a try and report back!
