How to select the battery of desired type and rating out of so many available batteries?
For example if I wish to support a 20 KW system with back up of 1 hour, 3 hours and 5 hours then what should be the ratings of the different battery banks respectively.

How does the battery voltage affect the performance of the system?
For example some people suggest 2V, 2000Ah battery while others suggest 240V, 250 Ah battery or 240V, 650 Ah battery for a 20KW system. Is it beneficial to have higher voltage rating batteries?

What are the parameters to be checked while selecting a inverter apart from its efficiency and rating?

In market people speak of area required per KW is different for different areas. How do we decide it? I mean is there any specific software used to calculate the same?
For example if we speak of Jaipur some people suggest 15 sq.m./KW is required while other specified somewhere around 12 sq.m./KW is required.

Whats is the basis of deciding the gap to be given between the modules and arrays? Is there any specific software used for the same?
