Get high up to install large sort of panel (5)
I believe the answer is:
solar
'get high up' is the definition.
I can't judge whether this defines the answer.
'to install large sort of panel' is the wordplay.
'to install' is an insertion indicator (inserted letters are installed).
'large' becomes 'L' (eg in clothes sizes).
'sort of panel' becomes 'soar' (I can't explain this - if you can you should believe this answer much more).
'l' put within 'soar' is 'SOLAR'.
Can you help me to learn more?
(Other definitions for solar that I've seen before include "chamber in old house" , "like a star" , "of heavenly body" , "Relating to our star" , "Coming from the sun" .)
