Emulator Solar Panel

A fierce competitor in renewables.

Emulator solar panel. A new pv emulator to evaluate the i v profile of solar panels. It is a flexible instrument designed to emulate the output of solar panels. To achieve the target of solar generation by 2022 the approach and methodology opted should be made faster efficient and cheap. It generates electricity regardless of position and orientation as long as it is extended.

The dc power supply operates as a current source to emulate the photo generated current that is usually generated by actual solar irradiation for outdoor pv panels whilst the open circuit voltage of the pv. A similar low bid strategy led to china s current world leadership in wind and photovoltaic solar. When it is extended it can generate 1 unit of electricity per second statically. The incidence angle changes from 49 to 82.

With fast transient response the emulator responds to change in load conditions and maintains the output on iv characteristics of the selected panel for a given ambient condition. The proposed solar pv emulator has the following features. Both parts function in similar capacities however the array with its larger. With fast transient response the emulator responds to change in load conditions and maintains the output on iv characteristics of the selected panel for a given ambient condition.

The solar pv emulator is a programmable power supply designed to emulate solar panels. 1 ease in interfacing with faster dynamic response 2 ability to monitor and control in real time using a control desk 3 higher. The paper notes that while in 2005 chinese companies held only 1 of the global wind manufacturing capacity today almost 50 is chinese and that its domestic wind market is installed at 40 lower costs compared to its european and american counterparts. Pv emulator is contributing towards this by providing an easy platform for testing and designing in dynamic conditions along with less space and capital requirements electricity generation from the photovoltaic pv systems is a major renewable energy source as.

In this paper a simple novel pv panel emulator was constructed by connecting an indoor pv panel and a dc power supply in parallel. Another similar part is the solar panel array. These pv emulators were developed using custom built power supplies or modified versions of commercially available power supplies. The current and the voltage generated by the emulator under the same conditions show a perfect agreement with those delivered by the photovoltaic panel.

Most of these pv emulators take a mathematical model of a solar cell which is based on specific cell parameters and calculate the emulator s voltage and current characteristics based on this model. The emulator combines the measured solar irradiation with an estimated incidence angle to determine the actual irradiation received by the panel.
