Simple and straightforward 💪🏼👏🏽👏🏽👏🏽 . Watching from Zambia 🇿🇲
Watching in Port Moresby, Papua New Guinea. Appreciate the knowledge and tutorial. Very vital information to design a small solar system for a basic home. Thank you for sharing the knowledge. God bless
Great work, thanks for impacting knowledge.
Outstanding explanation!! I learnt a lot. Thanks
Excellent explanation.
This is power expended to charge the batteries. What if one wants to utilise power on utensils while at the same time charging the batteries, how is total power calculated?
exactly
you will need to calculate the wattage of your utensils and divide that by the average of the panel charging capability (which is 0.65 in this example) the closer the answer to 1 the better and even better if it is between 1 and 2 then add the amount of of panel to your calculated system
utensils wattage TIME the amount of panels Divided by the average of the charging capability of the panels
i hope that helped
Nice one sir, well understand
🙏
Hello sir
I love your teachings
Thank you very much
You've the best explanation! I want to buy 290ah two batteries which according to your formula would need 1400 watts of solar panel. I have currently 3200 watts of panels but I'm also running 1800 watts Air Conditioner during the day on solar. Do you have a formula for that? Will the batteries be charged to 100%?
14…100 watt panels or 7…200 watt panels to charge ONE 12 volt battery…..that is if you have 10 hours of sun each day.
Thanks.
Will the calculations be different if it where a tabular battery?
I need panel for 12v 200 amp lifepo4 battery, what size should I buy? I also have an inverter that I will use for camping. What would you recommend for a mini fridge, phone and light?
If it's 4 unit of 200ah battery connected in 24v 400ah
Will the 4 batteries be calculated as 24v × 400ah to get whr
Can review 280ah lifepo4 battery, how many panels needed
If I were to purchase a solar panel that has a rating of 430 watts and operates at 45 volts, but my system operates at 12 volts, will the panel still produce its full 430 watts on my 12-volt system, or will the wattage be reduced to match the lower voltage of my system?
Great explanation Sir. .💪
Thanks and welcome
This DOD is it written on the battery body ?? or how do we find the DOD of a battery
It is not written anywhere. You decide how long you want to use battery.
If I have battery lead acid how many solar panels of calculations
Will I connect the 3 in series?
Sir how are you doing How to do the calculations for 24volt and 48volt system
can you please calculate for lithium batteries?
Ok
Please sir,if I have for instance 4baterries of 12v 200ah.Is it correct to multiply 12v x800?
Yes.that's a 9600wh of energy you have got.
Sir, thank you for the knowledge. Sir i want to ask: the 0.65 performance ratio that you use to calculate the battery whr, where do you get that figure from sir?
Was the performance ratio from 80%, 70% that is usually written in battery info. Was it that figure that am gonna use to calculate the battery whr to get my panel size?
Thanks for the information
That is an assumed rate of efficiency.Most solar panels are made with inferior materials, consequently their efficiencies are usually below par.Say instead of 100% you use 65% to get close to reality.So 0.65 is 65% solar panel efficiency. There is nothing wrong in using higher efficiency rate in your calculation if you are sure of the Panel you using.
Sir do you have any solar manual pdf
Yes...

Thanks
What is DOD?
Depth of Discharge
Excellent
How do I know my DOD?
Check specifications on your battery's name plate or the specification sheet of the battery
Thanks very much for sharing great knowledge.. I really appreciate it.. I'm watching your canal from Mali Bamako, please you'll let me receive your watsapp number as for well understood right please please 🤝💯
