A Sherpa should manage to carry 3 x 250 W PV panels "with ease". (Only 18 kg each :-). Rather large. BUT I in fact do expect that 3 would be the minimum they would consider. Anchoring gear would be a bit heavier than the norm in this application. 1 kHWh should give 100 litres of Oxygen/day. Hydrogen double that. Each 250 W panel should be good for 1 kWh per day in the silly season on a clear day - and may make a good roof it it can be persuaded not to blow away the rest of the time. Mount these at the bottom of the death zone or pehaps paper the Hillary step with them ... . Everest has an ongoing mean death rate of about 10%. Even as the gear etc gets safer and the footpath* to the top gets more defined the fodder gets less capable to match. On a good / bad / busy day you can see 200 people traipsing up Lhotse !!! :-(. Russell * Too hard a footpath for me. It's still horrendous. What it was like when Sir Ed managed it is beyond imagining.
