Your 30A PWM controller can use the power from 1-4 panels to (inefficiently) charge a 12V or 24V battery. All you need is a controller that can use the power from 20+ panels to (efficiently) charge the 350-400V battery in your car. There is no need for a wasteful extra battery, inverter, etc. Just one simple, cheap and efficient SCC.
The solar panel voltage specs may be anywhere between 18V and 24V. A relay is introduced in the circuit and is wired with the LED module such that it's switched ON only during the night or when it's dark below threshold for the solar panel to generate the required any power.
For example, if the open circuit voltage of your solar panel is 20V and the battery to be charged is rated at 12V, and if you connect the two directly would cause the panel voltage to drop to the battery voltage, which would make things too inefficient.
This must be precisely set such that the emitter produces not more than 1.8V with a DC input of above 3V. The DC input source is a solar panel which may be capable of producing an excess of 3V during optimal sunlight, and allow the charger to charge the battery with a maximum of 1.8V output.
Multiplying 80 by 12 gives = 960 watt hour. It implies that the solar panel will need to produce this much watt hour for the desired period of 12 hours during the entire day. However since we don't expect to receive optimum sunlight through the year, we can assume the average period of optimum daylight to be around 8 hours.
You can add a diode in series with the positive wire of the solar panel. It can be a 1N5402 diode The battery can be any 3.7V 1200mAh Li-ion battery. Motor can be any 3.7V DC motor. More Questions: Couple more questions, I cannot find a solar panel with those specs, do you think you could send me one on the internet so I can find something similar?
My Reply: yes, it will work. Use a 6 to 8V 1-amp solar panel. The switch in series with the battery is not required. The remaining two switches are fine. This switch can be replaced with a 4 ohm 2 watt, or simply a 6 V flashlight bulb. This bulb will illuminate while charging and will slowly shut off as the battery gets fully charged.

I have two 100 watt 18V solar panels that would plug right into the 200W DC car input. I was curious to know if you ever ended up trying to plug your solar panel directly into the DC input? If so, did it work? Thanks, any insight would be helpful, as I would like to use what I have rather than buy another panel.
