ABSTRACT

 The challenges ofthe use ofsolar PV in tropical regions located in the coastal belt are enormous. For example, Lagos Nigeria is a typical example oftropical location along the coastal belt. The uses of solar PV panel have been hugely inconsistent. The hype on the use ofsolar PV panel have doused by the low lifespan and energy output of PV panels Edeghe, (2016). Hence, fossil fuel generators are gradually replacing renewable energy options. However, while the PV companies keeps improving on their products to Nigeria, it is observed that the use ofsolar collector may be a better option for local farmers, domestic energy users and small businesses. In this review, the focus is on solar electricity generating power using solar concentrator. Solar thermal systems are gradually influencing the energy markets as it makes use of heat from the sun to generate electricity. Hence, the emphasis on the use of solid-state device to generate electricity from the sun is gradually becoming obsolete because ofthis technology known as concentrator solar power (CSP) technology. This paper provides a comprehensive review ofsolar concentrators and their benefits to make solar technology affordable. It also analyses some ofthe existing solar concentrators used in the solar technology for the past four decades. The design and performance ofthe concentrator are explained and compared under several conditions such as Temperature, humidity and solar irradiance.
