There are different ways solar panel battery chargers can work. Some can charge the products directly from the panel while others have an internal battery that needs to be charged first, and then discharged to the linking device. For example, smaller electronic devices, solar panel battery chargers should have an internal battery, because solar power isn’t continuous; it has fluctuations depending on the sunlight available. If there is a spike in charging while the device is still directly connected to your cell phone, it could fry the battery in that phone. Many larger solar battery chargers for cars and RVs have a built in surge protector to prevent this from happening.

The advantage of using a solar panel battery charger with a built battery is that you can buy a smaller sized panel, which would save you money. The disadvantage, however, is that the internal battery may not have a very long lifespan and it may take longer to charge it because the solar panel is small. A larger wattage panel charger also has its pros and cons. Usually, these panels are available in sizes of 5 watts or more and a good wattage rating is general 15 to 20. While these larger panels can charge a laptop for a short period of time, it’s important to make sure you also use a regulator in order to prevent spiking in times of increased charging.

If you are considering using solar panel battery chargers to power your RV or car battery, there are some points to think about. One is that while there are many chargers available in the 5 watt range, they are slow, trickle charging systems that produce less than an amp of power per hour. The same applies for a 15 watt panel. Basically, it requires more wattage in order to power larger batteries that many electronic appliances draw power from. In order to prevent your battery from draining, you need a panel that is at least 20 watts or more, and most people actually use at least a 25 watt panel.
