Abstract
Description
This work investigates the discrepancies in electrical parameters of monocrystalline
solar panels between Ago-Iwoye weather conditions and the
manufacturer’s specified ideal conditions. Manufacturer’s specifications are
typically based on 1,000 W/m2 global solar irradiance, AM 1.5, and 25°C
operating temperature, while actual weather conditions at installation sites
can vary significantly. Mono-crystalline (single-crystal) silicon solar panels of
capacities 60, 80, 100, and 150W were evaluated through current-voltage
(I-V) response tests at an installation site in Ago-Iwoye, Nigeria, with solar
irradiance exposure from 11 a.m. to 3 p.m. The analysis of I-V and P-V curves
revealed a significant reduction in maximum power output by 28.6%, 25.9%,
28.9%, and 19.36%, respectively, compared to the manufacturer’s stated values.
This deviation underscores the importance of considering local weather
conditions during solar PV projects, and we recommend adding an additional
20%–30% of the total solar panel capacity during installations to account for
variations in solar irradiance and operating temperatures, ensuring optimal
performance and effective solar power generation in Ago-Iwoye and
similar areas.
