Performance evaluation of polycrystalline photovoltaic modules in a Guinea Savanna and Mangrove swamp

This central idea of this research is to investigate how voltage, current, power output and efficiency polycrystalline photovoltaic (PV) modules installed in a Guinea Savanna Mangrove Swamp affected by temperature, relative humidity irradiance. The study locations are Calabar (mangrove swamp) Ogoja (guinea savanna), Cross River State, Nigeria. Two PV exact specification mounted on platform one-metre-high above the ground were used. A digital solar meter (SM206) flux (MS 6616) was used monitor measure reaching modules. hygrometer thermometer (KT-908) ambient temperature level at height installation multimeter (M880C+) accompanied with sensor current panel values from Analysis collected data reveals that not constant throughout day. However, higher voltage production obtained for module than under their respective levels humidity,
