Solar hot water in sri lanka

[MyNextCarIsAnEV]

Hi, I am interested in getting a solar hot water system. I have spoken to some of the major (I think) companies here,and one has a seemingly good discount on a system (they say they have been around since 1989). I am curious if anyone has experience with these companies or systems they can share. I am also wondering how reliable they are. 

I am hoping to get a 150-200 liter system with glass tubes, non pressure system.

I live at high altitude in a cold area so I'm interested in how well the function.

I searched the forums and could not find a thread on it, apologies if I missed one.

I had one from A*** T**** for the last 15 year with only one service to replace a pressure valve around 4-5 years back.

It is a 200L with copper tube and pipes.
