Solar Photovoltaic System and other associated concepts

Solar Photovoltaic system 1 lecture 00:00 Types of Photovoltaic System and some important terminologies There are four different types of Photo-voltaic system: Stand-alone or off-grid system, Grid-tie system, grid-tie system with power backup or grid interactive system and grid-fallback system.

Stand-alone Photovoltaic system- This type of system proves to be useful in a location where there are no other sources of electricity available. Stand-alone systems are comparatively small systems, with a peak power generation of within one kilowatt or less.

Grid-tie Photovoltaic system- This type of system is popular in the United States, Europe & Australia. In this type of system any excess energy produced by the PV system in a home is directly transported to the grid. The electricity grid further provides credit to customers for the amount of electricity received. Grid-tie system works well in hot, sunny climates where heat generation by the PV system is at a usual peak level.

Grid-tie system with power backup-This type of system combines a grid-tie installation with a battery bank. But unlike a standard grid-tie system, a battery bank acts as a power backup so that during power cuts power can be used from the PV system without any hassle.

Grid-fallback System- It is not a popular type of PV system.In a grid-fallback system, the solar array produces power which in turn charges a battery. The energy stored in the battery is further utilised to run an inverter to power the appliances in domestic homes.

Important terminologies

Air Mass1.5 - AM1.5 corresponds to a solar zenith angle of 48.2 degrees and indicates that light has travelled 1.5 times the vertical path through the atmosphere.

Solar irradiation- It is the integration of solar radiation over a give time and is expressed in kWh/m2

Solar radiation- It is the solar power per unit area received from the sun in the form of electromagnetic radiation and is expressed in W/m2

Important terms related to a PV system. 1 lecture 00:00 Important terms

Open Circuit voltage (Voc)- It is the maximum amount of voltage available from a solar cell and occurs at zero current. Voc decreases with temperature.

Short Circuit current (Isc)- It is the current available from a solar cell and occurs at zero voltage.

Peak Sun Hours (PSH)- It is the amount of hours in one day , when solar irradiance is consistently at 1000 W/m2. (1PSH =1000W/m2 for 1hr, 5PSH= 1000W/m2 for 5hr etc.)

Standard Testing Conditions (STC)- It is defined as temperature of 25 degree Celsius, irradiance of 1000 W/m2 and an air mass of AM1.5

Normal operating cell temperature (NOCT) - It is defined as temperature of 45 degree Celsius, irradiance of 800 W/m2 and an air mass of AM1.5.

Ingress Protection (IP)- Ingress protection which is mentioned behind solar panels in the junction boxes tells us how resistant the junction box is to solid particles and fluids.

Anti-islanding- Senses problem in the grid and shuts down the inverter to stop feeding power into the grid rong I= Current in...
