How do Solar Laptop Chargers Work
When you are going for long trips and you know that you won’t find any external power source, then solar chargers can be a useful way of charging electronics that use the energy of the sun to charge your laptops, tablets, or other electrical devices.
Typically, a laptop requires 16-18.5 volts of electricity for charging effectively on a solar panel and this much voltage can come from a solar panel of 60 to 100 watts. A laptop requires more power compared to other smaller appliances that’s why a bigger solar charger would be required to get 5 amps of current but the condition for that would be a sunny day with plentiful sunlight.
If due to some issue the solar panel delivers a higher current that means higher voltage will flow to the appliance which can cause damage to the appliance. Similarly, lower current means lower voltage that means the charging process will be slowed down.
Other than that, the connectors can be a real concern but almost all major PC brands come with different types of connectors allowing all solar chargers to connect easily with laptops as well as with power banks without using any adapters.
One thing that can cause trouble for you is that reverse polarity which is a phenomenon that occurs at night when the solar panels are not charging but instead they start taking the power from the laptop rather than giving. The reason behind this is that the panels are not getting sunlight so the voltage drops lower than the battery charge and they start fetching power from the laptop itself. To prevent that, make sure to use the blocking diodes.
You can track the conversion efficiency which is the amount of energy effectively converted into usable energy. Plus, according to the sun and weather conditions, the charging time can vary wildly from 12 hours to 30+ hours sometimes.
