Got it.

Sadly PV isn't IMHO the best ( cheapest ) way to generate electricity
when grid power is available since commercial panels currently are rated
at only around 15% conversion efficiency and cost a lot.

There's been a lot of talk about cheap 'thin film' panels but these only
come in at ~ 7% conversion efficiency ( electrical output / solar power
input ) and are not in volume manufacture, nor is their long term
reliability known. Also, conversion efficiency falls at high
temperatures due to the intrinsic conduction of silicon.

Do you have any insolation figures for Dubai ( nice airport you have btw
! ) and do you need to store energy overnight ?

esa7raa@hotmail.com a crit :

I did my engineering degree final year project on on solar powered
membrane distillation for groundwater desalination....

Plenty of information available in elsiever publications and different

You'll probably have more luck here if tell us exactly what sort of
solar desalination you are looking at.

What sort of desalinisation? RO? evap / distillation?

thank you very much for your replay
