The document discusses the installation of a 5 kW on-grid solar power plant using a net-metering system and solar inverter. It describes the different types of solar systems based on the inverter used - on-grid, off-grid and hybrid. On-grid systems can operate without batteries or with batteries for backup. Off-grid systems include batteries for backup when the grid is down. Hybrid systems combine solar with other renewable sources like wind or generators. The document also examines the advantages of different inverter types for on-grid systems - micro, string and central, concluding that grid supportive solar PV provides economic and eco-friendly electricity production.

ON-GRID Without battery
Advantages of ON-GRIDWithout battery(large scale) One time investment. Less maintenance required. Higher lifetime due to absence of battery. Grid-tie inverters are designed to shut down automatically uponloss of utility supply, for safetyreasons. Disadvantages of ON-GRIDWithout battery(large scale) They do not provide backup power during utilityoutages.
ON-GRIDWithbattery(smart grid concept)
Advantages of ON-GRIDWithbattery(smart gridconcept) They provide backup power for plant. Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. Disadvantages of ON-GRIDWithbattery(smart gridconcept) Maintenance required withproper schedule. They do not provide backup power during utility outages for Grid.
Off-GRIDPV System
Advantages of Off-GRIDPV System They provide backup power for plant. No requirement of grid supplyto stay ON. Disadvantages of Off-GRIDPV System Cost is increaseddue to presence of batteries. Proper maintenance required.
Hybrid PV SystemwithDG set
Hybrid PV SystemwithWind turbine & GRID
Advantages of HybridPV System it gives option for additional power though DG set or windpower. very cheaper than others. it is for bothON & Off grid.
Types of GridTiedInverters There are mainthree types of this inverters:- I. MICRO INVERTERS II. STRING INVERTERS III. CENTRAL INVERTERS
MICRO INVERTERS A micro-inverter consists of a small box located on the back of or situated very close to a solar panel. Its role is to convert the DC electricity produced by a singlesolar panel.
Advantages of Micro Inverters Gives panel level MPPT due to no transmission of LVDC. eachpanel is separated by each other. Panel level monitoring increase safetybecause no HVDC transmission. Less maintenance required. Disadvantages of Micro Inverters Higher costs in terms of dollars per watt Increasedcomplexityin installation
STRING INVERTERS A string inverter is the type most commonly used in home and commercial solar power systems. It is a large inverter box that is often situated some distance away fromthe solar array.
Advantages of String Inverters Robust 3 phase variations available Low cost Remotesystemmonitoring capabilities Disadvantages of String Inverters No panel level monitoring. highrisk due to HVDC.
CENTRAL INVERTERS Central inverters are designed for applications such as large arrays installed on buildings, industrial facilities as well as fieldinstallations they are basicallyjust a very large string inverter.
Advantages of Central Inverters Low capital price per watt Comparative ease of installation Disadvantages of Central Inverters Bulky in Size. Noise. A single potential point of entire systemfailure.
Advantages of Grid Supportive Solar PV System Economical. One Time Investment. Less requirement of maintenance. Eco-friendly.
Conclusion From this project we observed that this solar inverter is producing electricity free of cost by using solar energy so, its eco- friendly, pollution free and can be used for domestic appliances as well as for industrial purpose on three phase.
Thank you
