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

[@paulmshanga3310]

Simple and straightforward 💪🏼👏🏽👏🏽👏🏽 . Watching from Zambia 🇿🇲

[@kenmumina9944]

watching in kenya..numbering the video will help alot.

[@ernestobrazilian]

Outstanding explanation!! I learnt a lot. Thanks

[@Anointingify]

Great work, thanks for impacting knowledge.

[@charleschimfwembe5528]

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?

[@bokooo3129]

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

[@chambersdjc]

Excellent explanation.

[@KilaMichael-v9s]

Hi there, i like your program, can you please tell me how many solar panels should i use to use this 12v 150AH/10HR

[@nnamdi.ohaegbuchi]

Can review 280ah lifepo4 battery, how many panels needed

[@TutuNabie-qo7bd]

can you please calculate for lithium batteries?

[@Solarwattng]

Ok

[@TekeuFelix-kj8gj]

I love your teachings

[@Solarwattng]

Thank you very much

[@ahmedbendu5039]

Good day Sir, where do I position the Earth wire on my solar installation???

[@elijahCosmos-b4u]

Nice one sir, well understand

[@Solarwattng]

🙏

[@gafaradeyinka]

Hello sir

[@MBSUKTU]

I am using 180w 4 piece 220 tubalar battery and while charging I am using it for charging mobile phone and battery and MP. How can you advise me

[@ilamalihilustan22]

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%?

[@apongangh1654]

Sir! how much watts and voltage and maximum ampere is require for 12v 200ah lead acid battery from solar panel..

[@hamiresid7645]

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?

[@cyrilakpede7904]

Thanks. Will the calculations be different if it where a tabular battery?

[@homateipo1019]

Sir if i have 4 12v batteries and a 180watts panel. Is it possible to make the DOD lasts or should i need more panels??

[@richardkalu2308]

Great explanation Sir. .💪

[@Solarwattng]

Thanks and welcome

[@ngesconradnkwain4773]

Will I connect the 3 in series?

[@mmjalloh247]

Sir how are you doing How to do the calculations for 24volt and 48volt system

[@HadiCel]

If I have battery lead acid how many solar panels of calculations

[@wisecounseltv]

If it's 4 unit of 200ah battery connected in 24v 400ah Will the 4 batteries be calculated as 24v × 400ah to get whr

[@JerryMartins-vh9vc]

This DOD is it written on the battery body ?? or how do we find the DOD of a battery

[@Jackolltradez]

It is not written anywhere. You decide how long you want to use battery.

[@williamzee7748]

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.

[@IsmailMukail-wl6uv]

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?

[@IsmailMukail-wl6uv]

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?

[@sirt6505]

Thanks for the information

[@edwardzacchaeus1983]

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.

[@ezoguan]

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?

[@odahjosephodama]

Please sir,if I have for instance 4baterries of 12v 200ah.Is it correct to multiply 12v x800?

[@edwardzacchaeus1983]

Yes.that's a 9600wh of energy you have got.

[@linossinkala7840]

Sir do you have any solar manual pdf

[@Solarwattng]

Yes... selar.co/116611 Thanks

[@noelfaithfulkari2857]

What is DOD?

[@Solarwattng]

Depth of Discharge

[@jab376]

Excellent

[@godstimechason8984]

How do I know my DOD?

[@Le_vis254]

Check specifications on your battery's name plate or the specification sheet of the battery
