Solar MPPT VS Solar PWM

Regulator contains an important role in solar power projects, as they regulate the solar energy from the sun. There are two common regulators that are used in the industry, which are MPPT and PWM. In this video, one of our experience engineer will explain the differences between MPPT, and PWM with advantages and disadvantages.

It's not about loosing the voltage. If we connect 17v panel to 12v battery, which is, for example at 12.0v. The voltage on the terminals of the battery will start increasing from 12.0 till.. until the pulse ends. The charging current is proportional to difference between open circuit voltages. Lets say we don't want to charge higher than 14.4v. when we'll reach that voltage the controller should end the pulse. While not charging the voltage on battery terminals will go down to 12.x -13.x pretty fast. Then next pulse kicks in. We're loosing power between the pulses and it has nothing to do with voltage diff. Mppt has regulated voltage output so it charges constantly thus not loosing power. It also able to pull as much energy from panels as possible.

Good explanation.

[@psykopat81]

In other words, can the MPP device give a higher amperage value than the amperage value given by the panel?

[@acectrl]

MPPT cannot provide a higher amperage than what the solar panel is capable of. However, it can optimize the efficiency of the panel's output

[@psykopat81]

@@acectrl What I wanted to say was whether it could actually increase the amperage by reducing the voltage.
For example, while a solar panel that provides 15 volts and 7 amps is charging a 12 volt battery, the mppt device can output 14 volts and more than 7 amps. In this case, the 7 amperes coming from the panel are increased.
