For maximum and minimum temperature, coefficient of determination (R2) is above 0.95 which is a good result.
maximum temperature relational coefficient.
maximum temperature variation relational coefficient.
This study demonstrates that the the electricity consumption (EC) increases with mean monthly maximum temperature having significant correlation coefficient 0.412.
Similarly, maximum temperature has significant positive coefficients for maize, sorghum, rice and yam.
An improved mathematical thermo-electrical model is derived in terms of design, operating and climatic parameters of the hybrid solar collector to evaluate its important characteristics: collector flow and heat removal factors, PV maximum power point and its temperature coefficient, and overall power and efficiency.
The maximum intensity of PTC (positive temperature coefficient), the magnitude being ca. 9 orders, was found for a LMWPE/UHMWPE composition of 9/1 containing 23.5 vol% CF, i.e. a much higher amount of the filler than in the percolation threshold (12 15 vol%).
The cooling performance of such devices used in the refrigeration mode is examined in terms of the maximum temperature difference, heat flux density, and coefficient of performance.
The voltage at the maximum power point is known; consequently, the power at maximum power point (Pmp) is affected by the operating temperature Tc and can be considered to change linearly with the temperature coefficient of the power at maximum power point (μmp) [21, 22, 23].
In Equation 28, w 0 is the initial annealing temperature and equals 2·g max; g max is the maximum number of generations; a w denotes the annealing temperature coefficient whose value is slightly less than 1.
