Refering to the formula:

Battery capacity = (total load * backup hours) / battery loss * system voltage
. Always try to use red and black wire for the positive and negative terminal connection. installation of basic (standard) photovoltaic (PV) systems. Dear Mr Abhay, There are certain points responsible for you not getting desired backup. Hi Rahul, your requirement is unique.It is possible to make such auto switching equipment if yoy are ready to bear the cost. Also let me know if 200 watt panel will produce this much wattage per hour or per day , regards , Er Hari Singh Matharu. If the number of batteries are given, and you want to know the Backup Time for these given batteries, then use this formula to calculate the backup hours of batteries. In a large-size solar panel, this junction box has terminal wires with MC4 connector but for small size panel, you have to connect the junction box with external wires. this is superb.

Dear Wasim ,
Very Good Work.To much easy way to learn about solar and love this site.
Here I want to ask a question that in above calculation why you multiply 200Ah with 1/10 (charging time should be 1/10 of batteries) kindly clear this concept to me I shall be very thankful to you.
Regards
M.Kashif. For the upstairs loft, four 12-volt, 255-amp sealed batteries will store power collected by the panels. 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 . so plz dont use these formula’s.if the batteries is 150Ah the formula is=load*backup time/750=no of batteries. 0000050168 00000 n 0000031714 00000 n Hope that you can help me. INSTALLATION All Solar Panels must be grounded by electrical connection of the panel frames to ground. Solar equipment can cause cuts, scrapes, lacerations, gouges, and puncture wounds. Solar panel installation. ASW Thank you very much for the wonderful post, I wanted to ask that if I implement the above example as it is will it work? So you Can… But Do not ignore Safety.. as Charge controller control [regulate] charge for battery.. otherwise, the battery life will be reduce. Thank you. 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. Use the proper equipment and remember to take breaks to avoid getting fatigued. • The rated output of the panel is determined by the voltage and current that the solar panel can produce. 0000046314 00000 n Thanks to inform us about flexible solar panel which I want to connect with my solar freezer to save electricity. The solar panels in my own installation are at 15 degrees, and I only lose 4% in annual energy yield compared to the perfect angle. I have a solar panel of 48 V and 3KW inverter supported by a 48V 150AH battery bank of 08 nos. In fact the maximum current that requierd to charge a battery equal 15% from the maximum capacity of a battery. 16 panels of 150watts each 2. How many solar panels of 300watts. But a question raised below: Because this is a 12V inverter System, so if we connect these batteries in series instead of parallel, then the rating of batteries become V1 + V2 = 12V + 12V = 24V while the current rating would be same i.e.100Ah. generation benefits. sir i have 800va inverter with 12v , 150ah battery. 3.5KVA Inverter is to be used, 4#s of 12V/200AH Battery, Overall appliances consumption=1000 Watts (Points of light, TV set, Home Theater, Deep Freezer, One 1.5HP Air Conditioner and Two Ceiling Fans), Needed backup time=(8-10)Hrs.

We’ve outlined the five-step solar panel installation guide below: 1. 0000003950 00000 n Make the system in 144 volts by attaching 12 batteries in series and all the 6 modules in series. :). 0000008839 00000 n Therefore, we will connect 4 Solar Panels (each of 60W,12V,5A) in parallel. Heliocol solar panels are manufactured utilizing state- of-the-art solar technology and the most advanced production techniques. Call us (01 2544 140) Dear Nidhesh Sivan
Then what is the purpose of the above calculation…
try to calculate like this…come on man..its too easy.. Hi there, thnx for the useful information

I have installed 2 solar panels, 150 watt each long with 2 batteries 12 V 140 AH.

My load is 2 ceiling fans and 2 energy savers,

I want my batteries to be fully charged by SOLAR in 11 hrs of time (from 7am to 6Pm)

Why my batteries are not being charged fully in a day?

Thanks in advance, Read these two posts…and you will be able to get the ans…

Zubair, Sir,
Is it okay to connect three batteries in parallel,150ah 100ah 100ah, dear sir i have two solar panels of 30 w each and also 28 AH Gel batteries i have already connected them in parallel and using them as 12 v DC system but i also want to charge them on wapda in the absence of sunlight so that i can use it as a hybrid dc system please guide me the auto transfer switch diagram which should be in relay logic control or ready made controller model no thanks, But won’t that affect the charging time of the batteries. 0000032007 00000 n 0000041200 00000 n (i) Install an end panel first using 2 x end clamps. I would like to respectfully request to please check my work. DO IT YOUR WAY SOLAR SOLAR PANEL GUIDE ... our Solar Permitting Guide. Our website is made possible by displaying online advertisements to our visitors. Tighten nuts to 10 Nm. 0000005589 00000 n Two (Fld) Battery 100mAh. The solar panels in my own installation are at 15 degrees, and I only lose 4% in annual energy yield compared to the perfect angle. Which means 1 bank(2X12V Battery), it is below 15A. Can you please mail yr contact detail at atul161987@gmail.com or SMS on 9885018240. 4800 wh/ day from PV).considering losses and fluctuations is solar irradiation you may add 2 more 200 wp pv modules in parallel ( 2 s X 4 P X 200WP ). 1.4 The Notes will be reviewed regularly. Your email address will not be published. please tell me how connect of solar panel in 20 kw inverter and what rating of required solar charge controller for solar charging. Wire the solar panel: At the back sides of the solar panel a small junction box is there with a positive and negative sign for polarity. 3. GS001 04/19 2 . We need 1000W UPS / Inverter for solar panel installation according to our need (based on calculations). with Circuit, wiring diagrams and solved examples. as you have only 7.14 A current available from each of the module. Your blog was filled with interesting ideas! Everything seems to be fine and I can’t compromise on the Back up time i.e 7 hrs please help. In the scheme's early days, a system this size would have cost £10,000-£12,000. Hello Raj… The rating of Inverter should be 25% more than the load because of the output efficiency of the inverter and losses (As, UPS never provide 100% output). we need 360 W system for the above explained system (This is for both Direct Load and Batteries Charging), Therefore, we will Connect 6 Nos of Solar panels in parallel (each of 60W, 12V,5A). And finally, a 5500-watt power inverter and 40-amp charge controller will be installed in the garage near the standard electrical box. I was going to buy one 130watts solar panel to be used to charging a 12V 100Ah deep cycle battery, but when I turned to the back of the solar panel to check for specification plate, these are the information I saw: Solar Model type— SPM 130-12, Peak power (Pm)—- 130W, Maximum power voltage (Vm) —-17.2V, Maximum power current (Im, A 12V Solar panel gives about 22V(Open Circuit)
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. 0000004441 00000 n Note: The above calculation is based on ideal case, so it is recommended to always choose a solar panel some bigger then we need, because, there are some losses occurs during battery charging via solar panel as well as the sunshine is not always in ideal mood. Dear Sir, I have 2 nos of 12 volt 120 amp battery and 800 watt 24 volt APC Invertor. 0000005439 00000 n Will this work as expected at-all?
