The most appropriate method for calculating CO2 emissions associated with different renewable energy technologies (such as PV solar farms, wind turbines, etc.) is life cycle assessment (LCA) which will enable you to quantify the carbon footprint per MW of power produced from each of these renewable energy sources.
Examples of LCA tools include GaBi, OpenLCA, and SimaPro. To get familiar with the LCA methodology, please feel free to download my related published work on life cycle assessment and life cycle impact assessment (LCIA) from my profile under ResearchGate.net. In one of published work, I used LCA and LCIA to calculate the carbon footprint associated with renewable energy sources and compared them to the carbon footprint associated with conventional energy sources and nuclear power generation.
Hope this helps answer your question and good luck.

you need weather statistics first, as an input to any economic feasibility study.
you cant just rely/adopt the decision made for another type of premises. do you have sensitive loads that require continuous power supply? then you need some form of energy storage as well. not necessarily battery.
If the target is irrigation water puming, then either solar-PV, or wind sources are the most suitable alternative energy sources. This due their flexibility, and suitability to the irrigation water pumping. In addition, no electrochemical energy storage is required as the load is deferrable. The resource potential at the given site, costs, local manufacturing, and other constraints are among the governing key factors for the most techno-economically feasible choice. There some relevant publications in my RG profile from 2012-2017 handling solar-PV, wind, and their hybrid for irrigation water applications. You are welcome to read them.
