i have 4000 watts of load in a home the load will be 24 hours running how much size PV model(Array) i need and how much battery bank or storage,in day due to sun light the load will run on PV panel (nearly 8 hours )and will also charge the battery bank, at night when there is no PV charge the load will run on the battery bank charged during the day by PV.in case when there is no sun light or cloud or bad weather or any other problem in PV for 2 or 3 days there will be diesel generator to run the load and also charge the battery bank.Now i want how much size of PV Panels,Battery bank and diesel Generator i should use,(1) their hardware cost or capital cost or with their related components like inverters,converters,cables,chargers of battery bank etc.(2) installation cost(3)Maintenance cost(4)Replacement cost(5) shipping cost.need help in cast calculation mathematical modeling of above four types of cost (1) PV Panels (2) Battery Bank (3)diesel Generator
