the entire section RELEVANT to the post is:
"Influences on
Solar Power
Sunlight
Solar irradiation is measured in Peak Sun Hours (PSH).
The concept is like that of a rain gauge in that fluctuations are averaged: replace rainfall by sunlight and you have the general idea.
With three-way fridges, solar is practicable at 2 PSH.
With an efficient chest fridge it becomes practicable at 3 - 3.5 PSH.
For a medium-sized door-opening electric fridge you really need 4 PSH.
It's also advisable to have generator back up"
Using the analogy the nominated "2 PSH" is NOT used to power the three-way fridge, but ONLY the accessories, obviously you will also have to ADD the same "2 PSH" to both the other two fridge numbers also, for a realistic direct comparison.
Unless of course the "2 PSH" is already added to both the fridge numbers?
If that's the case, 1 PSH to 1.5 PSH will definitely run a chest type fridge daily?
With the three-way fridge running on gas, it's NOT relevant to battery recharging with a Solar panel, only the accessories are, but they are NOT mentioned, the fridge is and I have to believe what I read, not what I think it may mean and have it clarified on another page.
Yes, I believe it's very poorly written, as I've misunderstood the heading "Influences on Solar Power" to actually be inclusive of ALL the 3 fridge types nominated because it mentions the three-way fridge, it does NOT mention any accessories.
(maybe the other two fridge's were run off 240v anyway)
If you look further up I've stated I DON'T believe Collyn R wrote the update, as I'm definitely NOT attempting to discredit Collyn in any way, but to understand how a three-way fridge runs on 2 PSH.
( Yeahhh, I know it won't )
