What to Consider Before Installing Solar Panels for Electric Car Charging. Before installing solar panels for electric car charging, there are several factors to consider. One important consideration is the size of your EV battery, which can range from 40kWh for a Nissan Leaf to 100 kWh for a Tesla Model S or Model X.
Battery Charging Current: First of all, we will calculate charging current for 120 Ah battery. As we know that charging current should be 10% of the Ah rating of battery. Therefore, Charging current for 120Ah Battery = 120 Ah x (10 ÷ 100) = 12 Amperes. But due to some losses, we may take 12-14 Amperes for batteries charging purpose instead of

The C rate is a measurement that indicates the charge or discharge current of a battery relative to its capacity. For instance, a battery with a capacity of 100 Ah (amp-hours)
To charge a 100Ah 12V car battery with a 100V solar panel, you need a solar charge controller like MPPT for efficiency. Under ideal sunlight, it takes about 14 hours for a 100W panel to charge it.

The C rate is a measurement that indicates the charge or discharge current of a battery relative to its capacity. For instance, a battery with a capacity of 100 Ah (amp-hours) would have a charge or discharge current of 100A at a 1C rate. This means if you charged it at a rate of 0.5C, you would apply a current of 50A.

The voltage developed across it is monitored by transistor Q2. When the voltage across the 0.7Ω resistor reaches 0.7V, corresponding to a charging current of 1A, the base voltage of Q2 reaches about 0·7V and it begins to conduct, pulling the ADJ pin of REG1 lower to reduce the output voltage of REG1.

I don't know with which voltage it charges the battery but at the solar panel the voltage is kept at around 17 to 18v (mpp). At the battery I observed the voltage slowly climbs till the parameter I have set manually (14v) then it stops at that voltage and no current flows further.
The charge voltage is typically higher than the battery’s nominal voltage. This difference ensures the battery receives enough energy to compensate for losses during the charging process. Especially relevant in solar charging systems, charge controllers regulate the voltage and current from solar panels to the battery.

The solar to battery charging efficiency was 8.5%, which was nearly the same as the solar cell efficiency, leading to potential loss-free energy transfer to the battery.
Conventional design of solar charging batteries involves the use of batteries and solar modules as two separate units connected by electric wires. Advanced design involves the integration of in situ battery storage in solar modules, thus offering compactness and fewer packaging requirements with the potential to become less costly.
The charge voltage varies based on the battery’s chemistry and state of charge. A battery’s state of charge (SoC) indicates how much energy remains. A fully discharged battery has an SoC of 0%, while a fully charged one sits at 100%. Understanding the SoC is pivotal when calculating how much energy a battery needs to reach total capacity.
