“…Average correction factors calculated for 12 months of the year, on the basis of 24 -month measurements conducted between 07.2013 -06.2015, describe the relationship between monthly electric energy generated by a photovoltaic module in a fixed configuration and value determined using general formula (15), for central Poland. Table 2 presents calculated correction factors of monthly electric energy for a fixed photovoltaic unit.…”

Abstract. The paper presents a physical construction of a measurement stand consisting of a photovoltaic module operating in a fixed optimal configuration and in a solar tracking with a modified astronomical positioning. In order to reduce the electric energy consumption by two direct current linear motors system is positioned three times a day during winter months. Prepared energy balance, using annual measurements, confirmed the legitimacy of using twoaxis Sun tracking units for central Poland. Basing on the daily and monthly electricity production and solar irradiance for both photovoltaic units a mathematical formula with proposed correction factors is presented to calculate with good accuracy monthly electric energy generation for a fixed photovoltaic installation. The results of calculations were compared with measurements showing good correlation.

“…Also referred to as active sun-tracking system, its main essentials consist of two motors (one only for a single-tracking system), a microcontroller, a comparator and a power supply (Juang & Radharamanan, 2014;Yilmaz et al, 2015). Micro-controlled motors command the navigation of PV arrays latitudinally and longitudinally whereas the comparator is there to ensure that the incident sunlight is received at maximum.…”

Optimal exploitation of the costless and self-sustaining solar energy has been a concern of much research in response to pressuring energy demands in one hand and the effects of relying on energy sources which are harmful to the humans and the environment on the other hand. The conversion efficiencies of photovoltaics (PVs) as well as their production costs have therefore been research targets. However, factors such as unsatisfactory exposure to the available sunlight, weather-dependence of the sunlight and shading, temperature rise at cells' junctions as well as manufacture related-defects still remain major causes of PVs' underperformance which manifests in lower levels of output power and efficiency. The dynamics of the output power or current with respect to the potential differences at cells' junctions are usually graphically illustrated with two-axis plots, which imply that only two parameters get evaluated against each other at a time.In this paper, three-axis plots were further used to evaluate the output parameters with respect to a simultaneous change of any other two parameters involved in the model of the PV cells; which gives a more realistic and comprehensive picture of the performance of PV cells. In addition, causes affecting the output and efficiency levels of cells are critically reviewed
