DESIGN AND ANALYSIS OF A 5KVA GRID-INDEPENDENT SOLAR PV SYSTEM FOR ACADEMIC LOAD SUPPORT IN COMPUTER ENGINEERING
Abstract
This project presents the design, implementation, and analysis of a 5kVA off-grid solar photovoltaic
(PV) system tailored to meet the energy demands of the Computer Engineering Department. The
methodology followed a structured four-phase approach: energy audit, system design, installation,
and performance evaluation. A comprehensive load assessment revealed a total daily energy
consumption of 8.83 kWh, which was adjusted to 10.6 kWh with a 20% safety factor to account for
losses and future expansion. System sizing accounted for 25% energy losses, resulting in a required
solar array output of 11.8 kWh/day. Based on 5 peak sun hours, a 2.49 kW solar array was designed
using six 415W monocrystalline panels connected in a single series string. Monocrystalline technology
was selected for its high efficiency (≥20%), superior performance in high temperatures, and space
efficiency. Electrical configuration ensured compatibility with inverter specifications, maintaining
voltages within safe and MPPT ranges. Installation adhered to NEC and IEC standards, including
proper grounding and surge protection. Results confirm that the system is electrically safe, efficient,
and capable of meeting departmental power needs. The design includes scalability for future
expansion and resilience against environmental and operational challenges, making it a sustainable
and reliable energy solution for academic environments.
