[PDF Version]Simple solar charger circuits are small devices which allow you to charge a battery quickly and cheaply, through solar panels. A simple solar charger circuit must have 3 basic features built-in: It should be low cost. Layman friendly, and easy to build. Must be efficient enough to satisfy the fundamental battery charging needs.
A 12V solar battery charger utilizes the same 12V current during the charging state as shown in the efficient automatic solar-power-based battery charger circuit schematic. This circuit is designed to charge 12V SLA batteries from solar-based cells. The circuit uses an LM317T voltage controller IC.
Place the solar panel in sunlight. Check the battery voltage using digital multi meter. Circuit is simple and inexpensive. Circuit uses commonly available components. Zero battery discharge when no sunlight on the solar panel. This circuit is used to charge Lead-Acid or Ni-Cd batteries using solar energy.
As soon as the battery voltage, is under 13.5 volts (usually the open-circuit voltage of a 12 V battery), transistors Q1, Q2, and Q3 switch on and charging current passes through the solar panels as intended. The active green LED shows the battery is getting charged.
A solar-oriented battery charger is used to charge Lead Acid or Ni-Cd batteries using solar energy power. The circuit harvests solar energy to charge a 6volt 4.5 Ah rechargeable battery for various applications. It includes a voltage and current regulator and over-voltage cut-off features.

The FlexSolar 40W is a high-output, easy-to-use charger that can quickly unfold from the size of a large book into six linked solar panels. This medium-capacity panel has a DC output that can charge portable power stations, as well as USB-C and USB-A outputs for smaller devices.
Once you get an idea of charging capacity and your intended use for a portable solar charger, it's time to figure out what devices you plan on using. For smaller handheld items such as smartphones, a portable solar charger with five to fifteen watts should suffice.
The first thing to consider when buying a solar charger is the size of the panel. Chargers with smaller solar panels typically generate fewer watts, which is a measurement of power, while larger solar panels generate more. The larger a panel is, the more sunlight it can convert to power, and the quicker it can charge your devices.
Portable solar chargers don't have this problem, and as long as the proper conditions are met, they can provide a practically unlimited supply of electricity for your mobile devices, flashlights and battery packs or portable chargers. Compact and lightweight, they're perfect for camping, travel and emergency use.

Size, weight, and mounting features are other key considerations. Small, foldable, and light solar chargers are more common now. Despite their size, they can produce usable amounts of power thanks to advancements in solar panel efficiency. Chargers may come with backpack mounts, kickstands, frames, or other mounting solutions.
If you will be backpacking with your charger, we recommend getting as small of a panel as possible that will still generate enough power for your needs. If you're not going to carry your solar charger long distances, a larger size will generate more power to keep more and larger electronics running while you're out.
