Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.
Automatic solar tracker is a system which helps to boost the energy production of solar panel. The whole system even does not need any external power source, This document describes a dual axis solar tracker that uses sensors and a microcontroller to rotate solar panels to maximize electricity generation.
Instead, it only draws electricity from the mains to power your loads when the batteries are depleted. In some cases, the solar system does not connect to the grid. So the auto solar transfer switch must toggle the load between the PV system and a different source, such as a generator.
The system uses a microcontroller to power a stepper motor that adjusts the position of photovoltaic panels to maximize solar energy collection. Hardware components include a transformer, voltage regulator, microcontroller, push buttons, relay driver, stepper motor, and other electrical components.
Also, in RVs when connecting to shore power or generator. An RV solar automatic transfer switch is installed in an RV. Here, it provides a convenient means to connect or disconnect your loads from solar power to shore power. That way, your RV can remain powered even when the solar system is not producing electricity.
It aims to utilize maximum solar energy by using a solar panel that tracks the sun's position with help from light detecting resistors and a microcontroller. This is more efficient than stationary panels as it allows the panel to remain perpendicular to the incoming solar energy.
