How do you choose a panel?

[s18mcn]

Hello everyone,

ive just started to get into pv with my mcs accreditation date just around the corner!!! the question im asking is how do you decide what panels to you? Do you use the same panels/make all the time ? i know i lot depends on roof space available but when pricing against other companies how do you make sure your competitive?

with the roofs so far its had to be Sanyo as limited space, but ive only seen a few as just started out.
