1. The amount of sunlight that your location receives.

2. The efficiency of the solar panel.

3. The type of battery you are using.

4. The depth of discharge of the battery.

5. The charging voltage of the solar panel.

Assuming you are using a standard lead-acid battery, in an average location that receives 4 hours of sunlight per day, you would need a solar panel with a wattage of at least 400 watts. If you are using a more efficient solar panel, or if you are able to get more sunlight per day, you can use a smaller solar panel.

If you are using a deep cycle battery, such as a gel cell or AGM battery, you will need a larger solar panel. This is because deep cycle batteries can be discharged to a much lower level than standard lead-acid batteries without damaging the battery.

The charging voltage of the solar panel is also a factor. Most solar panels have a maximum power point voltage (Vmp) of 18 volts. However, some solar panels have a higher Vmp, such as 24 volts. If you are using a higher Vmp solar panel, you can use a smaller panel to charge the same battery.

In general, the larger the solar panel, the faster it will charge the battery. However, there are limits to how fast a battery can be charged. If you are using a lead-acid battery, you should not charge the battery faster than 10% of its capacity. For example, if you have a 100 amp-hour battery, you should not charge it faster than 10 amps.

If you are using a deep cycle battery, you can charge it faster, but you should still not exceed the manufacturer’s recommended charge rate.

It is also important to consider the type of battery you are using. Lead-acid batteries should not be charged to more than 80% of their capacity. Deep cycle batteries can be charged to 100% of their capacity.

If you are unsure of the best solar panel size to charge your 100 amp-hour battery, you can consult a solar sizing calculator.

What Does Amp Hours Mean On A Car Battery?

Amp hours, or AH, is a measure of the charge capacity of a car battery. It is usually expressed as a number of hours that the battery can deliver a certain amount of current. For example, a battery with a capacity of 100 AH can provide 1 amp of current for 100 hours, or 10 amps for 10 hours.

The AH rating of a battery is important to consider when choosing a car battery, as it will affect how long the battery will last and how much power it can provide. A higher AH rating means a longer lasting battery, which is why it is often seen as a good idea to choose a battery with a higher AH rating for a car that will be used frequently or for long journeys.

It is important to note that the AH rating of a battery is not the only factor that determines its performance. The age and condition of the battery, as well as the temperature, can also affect how long the battery will last and how much power it can provide.
