Artificial incubation is needed to multiply the chicken yield especially in the upcoming economies where the provision falls short of its demand. Heat is the major factor among the indispensable requirements of successful egg incubation. Hence, the main focus of this work is to identify the sources of energy used in poultry egg incubations and to determine the hatchability rate of the poultry egg incubators based on energy source used. The method of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was used. Series of eligibility/exclusion criteria were applied: only journal articles, peer reviewed conference papers and government publications were selected; articles in English publications were chosen as well. Only papers published from April, 2022 downwards were covered. The study found that sources of energy for egg incubation are categorized into grid supply electricity, solar system, fossil fuel, biogas and thermochemical materials. From the reviewed articles, 50% identified grid-supplied electricity as energy source for poultry egg incubation and hatchability ranges from 80.9% - 98.39%. However, due to erratic nature of electricity supply and non-availability in rural areas especially in developing nations, the study recommends increased research interest on other energy sources to improve their hatchability.

“…The electrical parameters and specifications of the solar panel provided by the manufacturer cannot be used to effectively determine the performance of the solar panel at the installation site because those electrical parameters do not always correspond to the actual parameters obtained at the installation site (Osanyinpeju et al, 2018). The manufacturer's specifications are usually obtained under a standard test condition of 1,000 W/m 2 irradiance, 25 °C cell temperature, and an AM 1.5 global spectrum.…”

“…In reference (Osanyinpeju et al, 2018), a study evaluating the performance of six 80-W mono-crystalline photovoltaic panels revealed variations in maximum output power compared to the manufacturer's at STC. The maximum output power obtained from the tested panels ranged from 53.1 to 59.4 W, with normalised output power efficiency ranging from 66.4% to 74.3%.…”

This work investigates the discrepancies in electrical parameters of mono-crystalline 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 150 W 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.

A variable amplitude and frequency of mechanical vibrating container working on cam and follower mechanism have been established. This study carried out a performance evaluation on the utilization of the established vibrating container for potential application in slowing down sprouting in yam. The vibrating container is electrically operated and a variable speed electric motor of 15, 000 rpm was selected for the machine. The performance parameters of the established mechanical vibrating container investigated were percentage maximum displacement and velocity of the vibration at different combined stages of amplitudes and frequencies. The percentage achievable maximum displacement of vibration measured for theoretical amplitude of cams of 5 mm, 10 mm and 20 mm were 89.40 %, 87.10 % and 72.7 % respectively for low frequency; 91.60 %, 88.40 % and 81.70 % respectively for medium frequency; and 93.20 %, 90.90 % and 86.50 % respectively for high frequency. The percentage achievable maximum velocity of vibration measured for theoretical amplitude of cams of 5 mm, 10 mm and 20 mm were 72.6 %, 71.40 % and 69.11 % respectively for low frequency; 79.81 %, 74.88 % and 70.96 % respectively for medium frequency; and 81.20 %, 77.52 % and 73.69 % respectively for high frequency. The results show that the established mechanical vibrating container has effective and suitable performances. The vibrator thus shows a good potential to effectively slow down sprouting when operated under load condition. It could help in slowing down sprouting in yams
