Just look at the back of your panel. They should be listing how many volts your panel should be producing. Another way is to estimate by counting solar cell count. First of all solar panels are a collection of solar cells. When the light hit them, they collectively produce voltage. Voltage production depends on environmental.

Customer ServiceWhile a step-down converter would also work, reducing the voltage from too high to too low is a bit of overkill. How Many Volts Does a 200 Watt Solar Panel Produce? A 200-watt solar panel produces 18 volts of energy, which is an ideal solar panel size for charging a 12-volt battery or to power a device that is also 12 volts.
Customer ServiceYou have a panel made for Grid Tied applications and can easily be used to charge a 12 volt battery. In order to do so you must use a MPPT Charge Controller, or what you are calling a Step Down Converter.

Customer ServiceBut to charge a battery with a solar panel, the most popular choice is the MPPT or maximum power point tracker topology because it provides much better accuracy than other methods like PWM controlled chargers. MPPT is an algorithm commonly used in solar chargers.
So the Solar panel is now behaving like a 66-watt panel. This equates to a loss of 100W-66.6W = 34W ( 33.4%). This is the reason for using an MPPT charge controller instead of a standard charge controller like PWM. The MPPT controller is consists of a DC-DC converter where the duty cycle is varied to track the Maximum Power Point.
It caps the PWM duty cycle at 99.9% to keep the charge pump working. There are two voltage divider circuits ( R1, R2, and R3, R4) to measure the solar panel and battery voltages. The output from the dividers is feeding the voltage signal to Analog pin-0 and Analog pin-2.
Efficiency of a solar charging system depends on the weather conditions. Usually the solar panel gets four to five hours of bright sunlight in a day. If the weather is cloudy or rainy, it affects the charging process and the battery does not attain full charge.
For loads which must run continuously to operate a certain system, a solar panel and charge controller is the sole approach. For this usage we advise, no less than, a 12V 40W solar panel with a 12V 12Ah SLA battery. For continuous operations, the MPPT solar charger circuit could consume approximately about 200mA.
The MPPT charge controller jumped all over it and started pulling more power from that panel. A traditional charge controller would have struggled and not been able to adjust like that. This illustrates why you need an MPPT charge controller on a solar panel. There's so much more that this custom PCB can do.
