I have Mono crystalline 12 V panels installed. I want to upgrade my Solar System by adding more panels. Can I add Poly crystalline 24 V panels? What are your suggestions while doing so?

HELLO SAURYA ENTERTECH WE HAVE A HOUSE IN ANDHRA PRADESH IT HAS 1000 SQ FT AREA WITH MONTHLY ELECTRICITY BILL OF 1500-2000 IN SUMMER WITH 2-4 HOURS POWER CUT, CAN YOU PLEASE SAY WHAT CAN BE THE COST OF SOLAR EQUIPMENT TO SUPPLY ELECTRICITY AT FULL PLEDGE TO OUR HOUSE? THANKING YOU PARVEZ

I have the month wise generation profile of a 1 MW Solar PV Plant (in MWh). But I need the load profile (MVA or MW) against the same. Is there a relevant way to get the same? Using CUF to compute it using back calculations doesn’t give a correct load output. Please reply ASAP.

My current solar system for home:
1. 12V 100W polycrystalline Solar Panel.
2. 12V 75Ah Lead Acid solar tubular Battery.
3. PWM 12V 10A Solar Charge Controller.
4. 12V Input and 200VA Output Inverter.

Current Problem:
Battery not getting charged fully daily because solar panel is getting around 3-4hours sunlight and that too includes sunlight at non-90 degree conditions.

So, I want to add an additional solar panel[preferably 200W or more] which will get 90 degree sunlight from 1pm to 5pm. Also, we get around 50 minutes of on grid supply. During this time inverter charges the battery too.

My questions as per my whole day research:

  1. If I add a 24V 200+W solar panel, I have to connect the panels in series because
    parallel means same voltage but ampere gets added.
    series means same ampere but voltage gets added.
    In this cases what changes are needed to charge the 12V battery?
    I guess someone will suggest MPPT controller. What is the best controller available in India? budget max6000INR

  2. To avoid huge costs and hastle for the above requirement if I go with 12V 150W panel, then I will just need to connect my 12V 10A with a new 12V 20A controller in parallel to draw 8.6+12.5A=22A approx. current from solar panels.Am I correct here?

  3. During a hot and shiny summer how much watts does a 100W panel produce in 90 degree sun conditions? What is the worst output that I will get in rainy season?

  4. While charging battery from the inverter during grid supply, I see the inverter shows around 6A-9A current supply to the battery. Is it the current only that counts how fast the battery goings to be charged. Does change in voltage play any role?

  5. I want to pull as much current as possible from grid and put it to my battery during that 50min time. What device will let me do so? Logically to charge a 12V 75Ah battery from 0-100 we will need something that putts 900W of power into the battery in an hour.
    900/12=70A approx. How much Ampere is safe for longetivity of battery?

P.S: In any circumstances safety and device efficiency is my priority.Please excuse any non-sensical thing if I mentioned above.

Hi,

The solar calculator showed that we consume 236KWh energy every month.
What is the best solar option to reduce our electricity bills?

Thanks

Can we install PVs in our unused land to produce energy. And what is the subsidy and loan we can get for the same. And what is the procedure to do..?

Hello everyone,

My name is Tarun and I’ve started a Solar Company along with two of my friends. My question is “what certifications and approvals we need to go through for doing Solar Installation and Trading(buying products from manufacturer and selling it to end customers)”.
TIA

Regards,
Tarun Tadiyal
