Africa has toward developing the solar grid system is the excessive temperatures in recent times. High temperature is found to lower the efficiency of photovoltaic panels (Ishii et al., 2011; Kurnic et al., 2011). For example, the beachfront temperature in the tropical belt infrequently transcends 32°C, while some other parts have running temperature extending in the vicinity of 32°C and 42°C.
The history of capturing solar energy from the sun’s rays began in the seventh century B.C when people

INTRODUCTION
It is already clear today that better overall efficiency of future energy systems can be significant if the use of renewable energy sources increases. The introduction of photovoltaic elements into modern architecture is the result of an understanding of the need to use renewable energy sources, in this case solar energy, in order to implement sustainable development principles. In terms of architecture, it is this technology, which marks its presence in the façade or on the

abolishing the excise duty on importing components of the PV system (Karekezi and Kithyoma, 2003). Some countries have recently implemented some informal renewable energy policies, for example, Kenya and Zimbabwe have removed excise tax on photovoltaic systems. The working modalities of the PV module depend on the make-up of the module (Janos and Elza, 2008; Brennan et al., 2014; Eduardo et al., 2014; Arnulf et al., 2015; Hugo et al., 2015). At the moment, the challenge of the PV is not tied to cost but

The paper proposes comparative study of Field Programmable Gate Array implementation of 2 closely related approaches to track maximum power point of a solar photovoltaic array. The current work uses 2 versions of kalman filter viz. linear kalman filter and unscented kalman filter to track maximum power point. Using either of these approach the maximum power point tracking (MPPT) becomes much faster than using the conventional Perturb & Observe approach specifically in case of sudden weather

The paper presents a Field Programmable Gate Array (FPGA) based tracker to accurately track the maximum power point (MPP) of a photovoltaic (PV) array. The tracking logic realized on FPGA is based on a modified version of Adaptive Perceptive Particle Swarm Optimization (APPSO) technique. Photovoltaic generation systems use MPP tracker because the photovoltaic array exhibits multiple maxima in the power voltage characteristic under partially shaded conditions. Compared to PSO, the APPSO offers

This paper presents the implementation of a fuzzy controller on the Arduino Mega board, for tracking the maximum power point of a photovoltaic (PV) module; using low cost materials. A dc–dc converter that incorporates a driver circuit to control the turning on and off of the Mosfet transistor was designed. The controller was evaluated in a PV system consisting of a 65 W PV module and a 12 V/55Ah battery. The results demonstrate the superiority of the fuzzy controller compared to the traditional

This paper describes an intelligent system for monitoring photovoltaic plants, detecting thefts or malfunctions and optimizing energy production by algorithm to drive solar trackers. Sensing/processing board detects environmental parameters and calculates produced power/energy for monitoring efficiency while anti-theft system reveals any critical condition. Designed board controls biaxial trackers calculating sun position and following solar orbit to optimize energy production. Monitoring and

temperatures. The cooperation between individual layers also has an impact on energy efficiency and on the microclimate of a given building. This paper will present different ways of energy activation in external walls with a special focus on the photovoltaic panels/modules (PV), the transparent insulation (TIM) and phase change materials (PCM). New materials can be included in the partition structure in different configurations such as a single or a bi-material component for improving thermal effects.

Solar trackers represent apparatuses that may significantly improve electric power production of photovoltaic panels. For detecting solar position, the trackers use different sensors (e.g. photoresistor, photodiode receiver, phototransistor, etc..). This research proposes an alternative way, the use of the sensor par excellence for retrieving solar radiation; the pyranometer. A design and tests have been performed in order to show the improvements. A comparison has been made between this

Wireless sensor networks (WSN) have limited lifetime due to on board battery. The lifetime can be improved by energy harvesting solutions. In this paper the solar energy harvester requirements for TelosB mote has been analyzed and calculated. Photovoltaic (PV) panel and battery sizing requirements are calculated by assuming that the mote follows SMAC and TDMA-MAC schedule for image communication. The calculations are validated by comparing it with the parameters calculated from the real time
