Hello fellow engineers and professionals,
I am currently designing a solar PV system for a residential household that would be needing around 16.4 KWh/day (from my calculation of the household appliances wattage and the amount of hours each is used per day, and then compensated for the inverter 90% efficiency). The PV system is a 12V system with 27 solar panels (250W each) in parallel, generating a total power of 6.7 Wp. All from my sizing.
When I size the battery for this system, I get approximately 91 batteries ( 12 V, 225 Ah Flooded Lead-acid Battery) each in parallel. To me, this does not make any sense and very experience from a financial point of view.
Please I would like some advice, tips, words of good thought and recommendations concerning my calculations. Do you guys (ladies included) think that my PV or battery sizing for this 16.4 KWh/day house is an over kill or just I don't know what I am doing? I did some research online and got those compensation factors from there. Any good book or author recommendation would also be helpful.
Any help or directions will be more than helpful and welcomed.
Thank you all ladies and gentlemen.
