This article examines an efficient solar photovoltaic (PV) system that offers easy access, neat installation, and a reliable grid connection.
The system discussed is a commercial 125 kW SPAR solar PV system, designed with walkability and convenient access to all panels, ensuring easy maintenance and inspection.
The panels are neatly installed on ventilated cable trays, while the inverters, which are 25 kW three-phase units, are arranged in a layout similar to the roof panels for easier management.
The AC cables used are three-phase and flexible, facilitating handling and dissipating heat through ventilated cable trays.
Additionally, the system incorporates security measures for panel and inverter protection. A 250 kW circuit breaker is employed for the main grid connection, located below the feeder transformers, ensuring a dependable link to the grid.
Overall, this system is characterized by its efficiency, accessibility, installation aesthetics, and grid reliability.
