charging station for tricycle (rickshaw)

[solarstation]

Hello,

I have the project to build a charging station for tricycles (rickshaw) using solar panels.

Each rickshaw has a set of 5 batteries, each battery is 12 volts and 120 ah. So for each rickshaw, the accumulator is 60 volt and 120 ah.

I need to charge each rickshaw, a set of 15 solars panels of 100 watt (5 panels connected in series to receive 60 V voltage and 3 rows connected parallel to receive 15 A current)

Therefore, if I want to charge 10 rickshaw every day during daytime, I need 150 solar panels and a total power of 15 kw

Are my calculations rights ?

Thanks for your advices and suggestions !

Are you serious?

Are you serious?

Yes we are very serious.

I wanted to add that we plan to charge the rickshaw using only a charge controller (directly with DC current from the panels)

Any suggestions or advices ?

Any opinion on the charge controller we should use ?

Does anyone even make a charge controller for a 60 volt battery system?

you may need even MORE panels. They never seem to meet the factory spec, and produce less - just like car mileage claims.

Midnight Solar controllers will do that. up to 72V battery bank settings. Pricey, if you need a bunch of them.

The problem is to get enough charge, fast enough, into the batteries. plain flooded will take a pretty heavy charge, without heating, from 0 - 60% full. Then things have to slow down. There are only about 5 solar hours in a average day, not counting clouds.
For such a large array, you need a large area with no shade. Shade is bad for solar panels. They don't work in shade.
You will need a backup charging source, either generator, or grid powered chargers. For that many stations, you will need several medium size generators, or charge fewer bikes.

I must be getting old. How could I have forgotten about that puppy.

I think it was the 60 volt battery system that had me going thinking most off grid systems are designed for 48 or 24 volts.
