Do grid lines reduce conductive losses in photovoltaic cells?

The shape of grid lines or fingers, used to reduce conductive losses in photovoltaic cells, is shown to be optimized when the current flux in the line remains constant. This result is derived for cells of arbitrary geometry assuming the fraction of the cell area shaded is small. The shapes of grid lines for three special cases are provided.

What is a technical assessment for a solar PV-based microgrid?

Technical assessment is based on the nature of the energy sources and the load of the microgrid. For a solar PV-based microgrid, the main technical aspects that are necessary to be considered include rating of PV modules, tilt angle, fill factor, MPPT, PV efficiency, and efficiencies of the power electronic converters.

What is a PV-based microgrid?

The name implies the principle component in a PV-based microgrid is the solar PV system. However, the generated output power of a PV system is dependent on the weather condition, that is, solar irradiance and temperature; and the intermittency in the solar irradiance causes fluctuations in the generated output power of the solar PV system.

Can a solar PV-wind hybrid system be designed in grid connected mode?

This method has not got a wide acceptance and can be found in few literature only . In Ref. , a decision support technique to assess the design of a solar PV–wind hybrid system in grid connected mode is presented.

How can a microgrid improve the reliability of solar PV?

In order to overcome the problems associated with the intermittency of solar PV and enhance the reliability, energy storage systems like batteries and/or backup systems like diesel generators are commonly included in the microgrids [11, 12].

Do PV based microgrids have a negative environmental impact?

Moreover, battery energy systems are also reported to have negative environmental impacts, which is also required to be taken into consideration while sizing/designing a PV-based microgrid [48 - 50]. In Figure 3, the common design considerations for PV based microgrids have been summarised.
