An on-grid solar power plant converts solar energy into electricity and connects it to the electrical grid. Key features include solar panels, inverters, mounting structures, and monitoring systems. Specifications involve voltage, frequency, efficiency, and protection measures. 
Key Features and Specifications:
Solar Panels: These convert sunlight into direct current (DC) electricity. Specifications include power output (Wp), voltage, and efficiency. 
Inverters: Convert DC power from solar panels to alternating current (AC) compatible with the grid. Specifications include voltage, frequency, efficiency, and protections. 
Mounting Structures: Support and secure solar panels, ensuring proper alignment and durability. 
Monitoring Systems: Track the performance of the system, including energy production and grid interaction. 
Power Conditioning Unit (PCU): Includes the inverter, MPPT, and protection devices. 
Grid Synchronization: Ensures the inverter output matches the grid's voltage and frequency. 
Protections: Over-voltage, over-current, over-temperature, lightning, and short-circuit protections. 
Certification and Standards: IEC, BIS, and other standards ensure quality and safety. 
DC and AC Switches: Control the flow of electricity. 
Cables and Installation Accessories: Connect the various components. 
Earthing and Lightning Protection: Protect the system from electrical hazards. 
Ingress Protection (IP) Rating: Indicates the level of protection against dust and water. 
Example Specifications:
Nominal Voltage: 230V/415V.
Nominal Frequency: 50 Hz.
Efficiency: >97% for the inverter.
IP Rating: Minimum IP-54 for internal units and IP-65 for outdoor units.
Operating Ambient Temperature: -10 to + 60C.
Solar Panel Efficiency: Minimum 20%.
Warranty: 25 years for the solar panels.
