Charge controllers are sold to consumers as separate devices, often in conjunction with solar or wind power generators, for uses such as RV, boat, and off-the-grid home battery storage systems. [1] In solar applications, charge controllers may also be called solar regulators or solar charge controllers.
Portable solar chargers are used to charge cell phones and other small electronic devices on the go. Chargers on the market today use various types 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 which offer efficiencies up to 18%.
A PV solar-powered pump system has three main parts - one or more solar panels, a controller, and a pump.The solar panels make up most (up to 80%) of the system's cost. [citation needed] The size of the PV system is directly dependent on the size of the pump, the amount of water that is required, and the solar irradiance available.
The simplest solar controller circuit uses a comparator with two temperature inputs, one at the solar panel and one at the thermal store's heat exchanger, and an output to control the pump. Commercial controllers use a microprocessor usually with a LCD display and simple user interface with a few pushbuttons.
Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...
