MPPT Charge Controllers High Efficiency

MPPT Charge Controllers High Efficiency

The solar radiation on a solar panel is highly variable, being dependent on the position of the sun relative to said surface. What's more is uncertain, being influenced by the presence-absence of the sun. A cell of a PV module performs for various values ​​of solar radiation, and for various values ​​of the temperature, a family of curves of the type in the figure below. In particular, there are three curves corresponding to three values ​​(1000, 800, 600W/m2) of solar radiation. On each characteristic curve exists one and only one point is maximized such that the transfer of power to a hypothetical load powered by the photovoltaic module.
Clearly, if you can maximize the power output from the system, you can exploit it to the fullest.
MPPT is a device integrated in the charge controllers that, typically, at each instant reads the values ​​of voltage and current, it calculates the product (ie, the power in watts) and, causing small variations in the conversion parameters (duty cycle), is able to determine by comparison whether the PV module is working in conditions of maximum power or not. Depending on the "response" is still acting on the circuit to bring the system in this optimal condition.
The reason why the MPPT are used is simple: a photovoltaic system without MPPT may still work, but for the same sunlight provides 30% of the least energy.
