If you have a 100W solar panel with a maximum power voltage of 18.6V, the solar panel’s max amps will be 100/18.6, which is 5.3 amps. In real life, however, the amps produced by the solar panel will be slightly lower. What is more important, watts or amps? Both are important. Amps determine how many watts a solar panel produces.
200 AH * 0.05 (5%) suggested rate of charge = 10 amps "generic" max charging current So, your 10.85 amps is certainly close enough for "solar work"... It's not clear whether you're putting together a 24V system, or a 12V one with an MPPT controller. Some controllers (e.g. Morningstar Prostar MPPT) have a setting to limit max charging rate.
The charge controller is one of the most important components of a solar system. Even portable solar generators have one built-in. A charge controller adjusts the current and volts coming from the solar panel and delivers safe power to the battery. It ensures safe and efficient charging.
The effect of single, parallel and series attached solar panel on Amps, volts, and power (watts) are explained above in the curve. The curve above shows that the solar panels attached in parallel circuit have more amp’s value due to which has more efficiency (higher watts value) compared to single and series attached solar panels.
Both are important. Amps determine how many watts a solar panel produces. That said, when it comes to sizing solar panels, watts is a more useful measure. That’s because it tells you how much power the solar panel produces and how quickly it can charge a battery.
A "constant voltage" source. Solar panels, for the most part, are "constant current sources". If you have an Imp = 10 amps solar panel (current maximum power)... Under full sun the panel will (for a first approximation) output 10 amps from zero volts to Vmp (voltage maximum power).
