As we mentioned earlier, a bigger panel-to-battery ratio is preferable in areas where you are not getting very much sun or if you live closer to the poles. Ideally, no matter your application, the 1:1 ratio is a good rule to follow, especially for small solar setups under a kilowatt. A 100-watt panel and 100aH battery is an ideal small setup; you can expand it from there.

The most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery.
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
The way the power capability is measured is in C 's. A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A. The amount of current a battery 'likes' to have drawn from it is measured in C. The higher the C the more current you can draw from the battery without exhausting it prematurely.
Capacity: The entire energy in a battery is measured here, and it is usually expressed in ampere-hours (Ah). It provides information on how much charge the battery can deliver at a particular discharge rate. Energy Density and Power Density: The quantity of energy stored per unit of mass or volume is measured by the energy density (Wh/kg or Wh/L).
The term "capacity," which is used to refer to a battery's ability to hold and distribute electrical charge, is indicated by the letter "C". It is a key variable that determines how much power a battery can deliver. The ampere-hour (Ah), which measures how much electric current a battery can produce for an hour, is the common unit of capacity.
Capacity is calculated by multiplying the discharge current (in Amps) by the discharge time (in hours) and decreases with increasing C-rate.
