DIY Solar Battery Charger with 12V Charge Controller. 

The 12V 35W DIY solar panel is powered by Crystalline photovoltaic cells. Our solar battery trickle charger are generally used for off-grid purposes. It is a more versatile  solar panel in terms of application. They are a smaller lightweight solar panel, specifically this solar panel weighs about 7.7lbs, making transportation and handling convenient. The 12V 35W Crystalline Solar Battery Trickle Charger can be use as a battery maintainer for the battery of automotive and marine. The 12V 35W Crystalline Solar Battery Trickle Charger can also come with battery clamps and cigarette lighter adapter, so you can use it in different ways under different circumstances.

This photovoltatic solar system has a bracket on back, so the panel will be positioned at an angle.


  • Off-grid solar project
  • Ideal for solar application
  • Lightweight, easy to transport and handle
  • Panel held at an angle by brackets attached to the back
  • Battery Trickle Charging Kit
  • Converts daylight into electricity to charge 12V batteries, extending battery life
  • Suitable for trickle charging a wide range of batteries and power packs
  • Blocking diode prevents reverse charging and protects battery discharge at night
  • Aluminium frame
  • Perfect for batteries stored in caravans, boats and vehicles in long-term storage

Potential Applications: Use the 12v DIY solar charger to keep your laptop batteries charged (using a 12v laptop charger).

  • Suitable solar charge for mobile phones. How? Simply connect your 12v car charger directly into this unit.
  • 12v Solar Battery Charger: charge any 12v battery using this easy to install 12v charging kit.


How Do Photovoltaic Solar Cells Work? 

Photovoltaics is the direct conversion of light into electricity at the atomic level. Some materials exhibit a property known as the photoelectric effect that causes them to absorb photons of light and release electrons. When these free electrons are captured, an electric current results that can be used as electricity.

The photoelectric effect was first noted by a French physicist, Edmund Bequerel, in 1839, who found that certain materials would produce small amounts of electric current when exposed to light. In 1905, Albert Einstein described the nature of light and the photoelectric effect on which photovoltaic technology is based, for which he later won a Nobel prize in physics. The first photovoltaic module was built by Bell Laboratories in 1954. It was billed as a solar battery and was mostly just a curiosity as it was too expensive to gain widespread use. In the 1960s, the space industry began to make the first serious use of the technology to provide power aboard spacecraft. Through the space programs, the technology advanced, its reliability was established, and the cost began to decline. During the energy crisis in the 1970s, photovoltaic technology gained recognition as a source of power for non-space applications.

The diagram above illustrates the operation of a basic photovoltaic cell, also called a solar cell. Solar cells are made of the same kinds of semiconductor materials, such as silicon, used in the microelectronics industry. For solar cells, a thin semiconductor wafer is specially treated to form an electric field, positive on one side and negative on the other. When light energy strikes the solar cell, electrons are knocked loose from the atoms in the semiconductor material. If electrical conductors are attached to the positive and negative sides, forming an electrical circuit, the electrons can be captured in the form of an electric current — that is, electricity. This electricity can then be used to power a load, such as a light or a tool.

A number of solar cells electrically connected to each other and mounted in a support structure or frame is called a photovoltaic module. Modules are designed to supply electricity at a certain voltage, such as a common 12 volts system. The current produced is directly dependent on how much light strikes the module.


see caption
Multiple modules can be wired together to form an array. In general, the larger the area of a module or array, the more electricity that will be produced. Photovoltaic modules and arrays produce direct-current (dc) electricity. They can be connected in both series and parallel electrical arrangements to produce any required voltage and current combination.

    This kit worths every single penny, although it is little more expensive than the typical trickle charger. But this guy actually more than a trickle charger. It is a Mono-crystalline solar panel, which mean it is so much more efficient than the typical thin-film (Amorphous) solar panel. It not only maintain your battery, it actually charges your battery.

    As T. Doc said, the panel is a monocrystalline solar panel. It charge the battery so fast. And the kit come with anything you will need, it comes with the jumper clamps, the lighter connections, and a controller.
