https://www.electricaltechnology.org/2012/12/how-much-watts-solar-panel-we-need-for.html, Hello sir, I need some clarifications

With regards to your above calculation you have stated that for a load of 800watts it requires two 100 ah battery for a backup for 3 hours. Sir, from the last point on finding the current for both charging and direct connected load, starting from where it reads “Now supposed there is some (directly connected to the panels through “inverters”)”. Your charge controller is designed to consume only 80% of your battery capacity i.e. Please give rating with calculations so that we can do our self in future because we are in field of solar. Be aware that this nominal ratio is given for standard test conditions (STC) : radiation=1000 W/m2, cell temperature=25 celcius degree, Wind speed=1 m/s, AM=1.5.

In order to decrease the calculation time, using certain mathematical expressions from the literature, the computer program for MS Excel has been developed. 1. Under the present set up if you want to employ the existing battery only,then you can connect 2 solar modules of 12V /150 Wp each in parallel to charge the battery In case if you want to have more back up you can include another similar rated battery in parallel to the existing one and connecting totally 4 solar modules of 150 Wp in parallel that will charge the total battery bank. I.e. There are some losses and efficiency factors playing a major role in output.

Battery efficiency : 0.8

if your using inverter then the factor is : 0.9

, Sir,i am working on a project.i have load of 120kWH/mnt . 2.67 / 0.8 = 3.34 amps. You have not taken the efficiency of Inverter, loss in charging battery, depth of discharge for batteries(DOD), and the panel efficiency , it is just a theoretical calculation which will not work in the practical scenario. Now i want to know how many 300 watt panels maximum can i couple to this system to give me more day power from the panels without damaging the controller.

In simple words;

Panel Wattage = 130W

Volts = 12V

So current would be

I = P/V → 130 / 12 = 10.83A (Ideal Case)

So you can use it for 12V 100Ah battery

and charging current for 100 Ah battery = 100Ah x (10/100) = 10A

and the charging time for this battery would be;

100Ah / 10 A = 10 Hrs (Ideal)

, In the event of a lithium battery are these charge times the same, or is there a difference in charge times for Gel, Lead acid and lithium.

Thanks for correction.. for a home solar electrification, they consumed of 16 amp of electricity per day.please give me a solar system and its calculations. Most load calculations include a discount factor for the inefficiency of recharging the battery. Many thanks for the reply. I would like to know why inverter rating is 25% more than the Load. But I think you didn't take in your consideration the change in the the temperature or the irradiation which will affect the output solar power.

. They are really helpful.

I will love to learn more from you sir and if possible and if you dont mind becoming my teacher on, Aslam-o-Alikum Sir, Im Kashif Raza from Lahore. Their names are derived from the active cell materials: 1. it converts all the solar energy into electrical energy then all you would need is a 1 m 2 solar panel to produce 1000 Watts of electrical energy. Sir mere pass single battery hai or 250 watt ki solar plate hai or uske upper 2 celling fan ka load hai.fir bhi kuch der fan chlane ke baad inverter whistle bajane lag jata hai.Isliye sir main iska karn puchna chahta hu. will that 200ah battery satisfy the load of 800w for 3 hours practically?? Limited Edition... Book Now Here. Suppose, we are going to install a solar power system in our home for a total load of 800W where the required backup time of battery is 3 hours (You may use it your own as it is just for sample calculation), Required Backup time for batteries = 3 Hours, Inverter / UPS rating should be greater than 25% of the total load (for the future load as well as taking losses in consideration), Our Load + 25% Extra Power = 800+200 = 1000 Watts, This is the rating of the UPS (Inverter) i.e. 1. 300W x 25 = 7.5kW…and you get 5.2kW…. At this stage connected load is 750 watt AC at day time and 400 watt at night. Dear Padma Priya@

Yes! Sir, I am a Civil Engineer . thanks for this work.

After the calculation i need around 220 AH battery is required for me. As per my knowledge A C10 battery (150AH) minimum charging current is 15A ,, in the manual panel it is fluctuating from 10 to 13A and on the inverter screen it is from 14 to 18.6 in peak time. Pls help me out here. Please also check and convey the availability of Grid power during the generation period. we want to use solar system.so how many solar panel required to 6 to 7 hour back up?now our battery back is 3 hours. Hello Bro

Can we connect the Solar Power directly to an inverter without batteries through a charge controller ?? pl advice. ( want to know solar panel in W, battery need to be used, charge controller and inverter VA). Example : the solar panel yield of a PV module of 250 Wp with an area of 1.6 m2 is 15.6%. We recommend the use of Section 6.5.12.4.1 and supporting Figures only for Solar panel =20 watt (20 watt is available) 2. I had requested a quote from a dealer for this setup and he is claiming he can put 600W panel that can concurrently run the 350W load along with charging the 150AH battery. Inverter of 2.4kva Battery of 200ahms(only one) Solar panel of 250watts (only one) Charger controller 30am… To control basic things at home eg one fan,3led bulbs,tv led only. I am really fascinated and envious with intelligent people here. Sandeep A hybrid charge controller can convert any inverter of any brand into an online solar inverter and it has nothing to do with the brand name. How many batteries? . Thanks, Hello engr.please i need advice on the comb if is right to go ahead.am not good in scientific language. hi i have a 650 watt inverter with 2 solar panel with 320 watt total and connected to a 400 AH battery bank (liquid aced type) but have an increasing in temperature for one battery. So anyways.These are the formula taken from various parts of the site.Please verify if they are correct or show me where I can tweak (Without getting ridiculously detailed,this is a … It’s not so tough compared to the hybrid generator installation, I can share with you the methodologies for Hybrid generator installations. Approximate load is 350-400W concurrent usage Was thinking of how to achieve the desired model Run Morning to evening daily home load(~350-400W) directly through solar Also in parallel charge the 150AH battery for backup purposes in evening. If I have 4 Solar panels, each having 350 Watts and 48Volts outout. Thanks for sharing your knowledge, it’s really enlightening. There is no sunshine for at least 10Hrs. Thank you sir. Solar Contractor installed 6 panels( Series of 3 Panels connected in Parrallel ) , each rating 200 watts connected with 8 batries of 100 Ah( connected 4 batteries in series to make 48 Volt Circuit ) with charge controller & Inverter . 1-800-472-1142. Thank you for taking time to share your knowledge. Is the calculation correct? If you put a day time load of 400 watts , it would give you a total back up of 7 – 8 Hrs per day. 9 November Thomas Karli Reis Allgemein designing string, serial modules. field test. Well friend but it will be very expensive installation!Start current for a such motor is about 80A……during 6 sec if start with load!Imagine what inverter size and how many panels will be necessary……I advice you take a cable from the grid!! [1] Figure 2.1 Solar Cell There are four advanced thin film technologies for making PV modules. Thanks! I would like to draw your attention to the average sunshine hours, as this is a major factor you need to consider when sizing a solar panel. this is really super helpful!!!!! 1. – Examples in British and SI System, Electrical Wire & Cable Size Calculator (Copper & Aluminum), https://www.electricaltechnology.org/2012/12/how-much-watts-solar-panel-we-need-for.html, https://www.electricaltechnology.org/2013/03/easy-charging-time-formula-for.html, https://www.electricaltechnology.org/2013/03/easy-charging-time-formula-for.html

In simple words;

Panel Wattage = 130W

Volts = 12V

So current would be

I = P/V → 130 / 12 = 10.83A (Ideal Case)

So you can use it for 12V 100Ah battery

and charging current for 100 Ah battery = 100Ah x (10/100) = 10A

and the charging time for this battery would be;

100Ah / 10 A = 10 Hrs (Ideal)

, In the event of a lithium battery are these charge times the same, or is there a difference in charge times for Gel, Lead acid and lithium.
