what weather station for my needs?

[tommydog]

I live in the far north of Scotland and am mainly looking for a weather station to monitor wind speed with a view to a wind turbine installation at a later date.  My plan is to leave the weather station erected for a year, so I can monitor every month. I would like something that can automatically produce summary graphs to show average and peak wind speeds per month.  It would also be useful if I could measure sunlight, as this will also give me an idea of viability of a solar panel install at a later date.  I am not bothered about measuring rainfall etc.

As I will mount the weather station on the roof, I have to think about power, as I don't want to have to frequently climb on the roof to change batteries.  I do have POE on my roof, but there don't seem to be many weather stations supporting POE.  One option I did find is this:

QWS-4000

But I am not sure how good / user friendly the above product is?  As I say, I ideally want something that can produce summary graphs without too much tinkering.  

I forgot to mention, I have good outdoor wifi coverage (have quite a few outdoor access point), so I don't need anything with 4G.

What are peoples thoughts for my application?
