I am designing a system for small industry where load is of around 25-30 KW.
Since the industry works only in day time, I want to provide a complete solar solution to it.
I have two question, it will be best if someone can guide me technicality of it.
1)If we have to design a off-grid system(Solar Panels,Inverter) do we always need to provide battery for it? Even if load will be catered only through solar generation during sunny hours.If yes, then why?
2)Can I design a system where battery will be very small and act like a supplementary source when there is insufficient solar irradiance, e.g if load is of 25 KW and solar panels producing 10 KW remaining load can be catered through battery, so battery required will be of 15 KW here. I am well aware of battery calculations, DOD factor,losses all, I am just giving simple example here as Diesel generator will be there for backup when solar is not present. But I want to cater most load through battery and solar only, that too only during sunny hours.
Kindly guide me in these two conditions.
