Solar Panel profit and real time measurements of power in watts by youtuber - Loss calculations

Note: Best to buy Solar if you dont have source of power or freequent power cuts or if you already have a inverter and battery and ready to spend for earning at 1 to 1.5% on average every month for your investment. 

Investing in Batteries for solar is Total loss if you have access to power from government. 

 Solar Panels required for 1000 watts 1kva.

1000 watts required at the output of Inverter

?required at the input of Input of inverter with 30% loss

=(1000X100)/(100-30)= 1429 watts. 

solar panels capacity required to get 1429 watts at input of Inverter with 10% loss = 1588 watts.

=1600 watts.

cost at 5000 per 100 watts - 

then for 1600 watts - 16 X 5000 = 80000/-

Investment 80,000/- without batteries for 1000 watts Maximum Load can be connected at any second.

if we assume 100% efficiency then 10X100 watts = 10 X5000 = 50000/- 

Profit Loss

per day production = 4000 watts on average. which is 4 times of panel capacvity.

Monthly = 120 units per month produced.

at Rs.7 bill per unit = 120 X7 = 840/- rupees Per month for investment of 80000.

which is 1% - (840X100)/80000 and it utilises so much of your space and causes inconvenience or rent loss of that space. 

even under 100% efficiency you will spend 50000/- and you save 840/-

which is 1.68% at Ideal condition.

which is lower than 2% interest, if businesses are making morethan this then it is not suggestable to buy.

if you are having excess money in bank which gives you lessthan 1% interest for your money then solar is good to go. ensure you have free space in excessalready. sparing some space especially for solars is a loss. 

if you are in loans with more than 1% interest or have a business which generates more than 1% then I do not suggested to buy.

Note: buying with batteries is more Loss. when we check all the losses and more investment.

at 1 PM it generated 94 watts

at 10 AM - 49 watt - 20 watt on cloudy day

1PM - 94 watt  even 103 at more sunny.

1:30 PM - 90 watt - 4 watt when it rained.

at 3:30PM - 82watt

4 PM - 76 watt

at 5PM- 13 watt

7 PM - 2watt

Day 1 - 590 watts but 50 watt hour on worst rainy day.

4310 watts produced in 10 days - 431 watts per day.

he also displayed how much it produced every day in Graph

the super consumer commented on it as bellow.

he also commented of the 12 pannels of 400 watts whiich is 4800 watts total capacity,  with invereter inbuilt which produced almost 4350 at peak which is 91% efficiency with Inverter. unbelievable.
