A solar charger employs solar energy to supply electricity to devices or charge batteries. They are portable .
Solar chargers can charge lead acid or Ni-Cd battery banks up to 48 V ampere-hours and hours (up to 4000 Ah) capacity. Such type of solar charge setups use an intelligent charge controller . A series of solar cells are installed in a stationary location (ie: rooftops of homes, base-station rentals on the ground etc.) and can be connected to a battery bank for energy use. They can also be used in your hands-supply chargers for energy saving during the daytime.
Most portable chargers can obtain energy from the sun only. Some, including the Kinesis K3, and GeNNex Solar Cell 2 can work either way (recharged by the sun or plugged into a wall plug to charge up). Examples of solar chargers in popular use include:
- Small portable models designed to charge a range of mobile phones , cell phones, iPods or other portable audio equipment.
- Fold out models designed to sit on the dashboard of an automobile and plug into the cigarette / 12v lighter socket to keep the battery topped up while the vehicle is not in use.
- Flashlights / torches, often combined with a secondary means of charging, such as a kinetic (hand crank generator) charging system.
- Public solar chargers permanently installed in public squares, such as parks, streets and streets, which anyone can use for free.
A solar panel can Produce has ranks of charging voltages DEPENDING upon sunlight intensity, so a voltage regulator must be included in the charging system so as to not over-load ( overvoltage ) has Device Such As a 12 volt car battery.
Solar chargers on the market
Portable solar chargers are used to charge cell phones and other small electronic devices on the go. Chargers on the market today use various kinds of solar panels, ranging from Thin Film panels with efficiencies from 7-15% (amorphous silicon around 7%, CIGS closer to 15%), to the Slightly more efficient monocrystalline panels qui offer efficiencies up to 18%.
The other type of portable solar chargers are those with which they can be transported from one place to another and be used by a lot of people. They are semi-public, considering the fact that they are used today. A good example of this kind of portable solar charger is the Strawberry Mini device. 
The solar charging industry has been plagued by the mass-producing low efficiency solar chargers that do not meet the consumer’s expectations. This in turn has made it hard for new solar charge companies to gain the trust of consumers. Solar companies are starting to offer high-efficiency solar chargers. When it comes to the public solar chargers, Strawberry Energy Company of Serbia has developed and developed the first public solar charger for mobile devices, Strawberry Tree . Due to a built in rechargeable battery which stores energy, it can function without sunshine or at night. Other companies such as Voltaic Systems, Poweradd and others have started to push the market.
Portable solar power is being white Utilized in developing countries to have power lighting Utilizing Opposed to kerosene lamps qui are responsible for respiratory infections, lung and throat cancer, serious eye infections, cataracts as well as low birth weights. Solar power provides an opportunity for rural areas to “leapfrog” traditional grid infrastructure and move directly to distributed energy solutions.
Some solar chargers also have an on-board battery which is the solar panel when not charging anything else. This allows the user to use the solar energy stored in their battery to charge their devices.
Solar chargers can also be rolled out flexible gold and are manufactured using thin film PV technology. Rollable solar chargers may include Li-ion batteries.
Currently, we are able to provide a platform for biking, hiking, charging, cellphone, tablet, computer and more. As advances in the technology continues to be made, new products will be able to expand to third world countries faster than ever before. Recently, billionaire Elon Musk has become more flexible than ever before, and can rely on grid-based systems that can only be used to power grid-based energy systems.
