“…High relative to Rsquared, which is close to 1, means that the PV system generates the most electrical energy. Meanwhile, Singh demonstrated the performance ratio obtained by PVsyst at Naresuan University, Thailand [5]. The performance ratio in each month is quite stable, which differs from the actual operation of this variation every month.…”

The performance ratio (PR) based on IEC 61724 standard is calculated under the influence of seasonal variations and the capability of the system. On the other hand, The National Renewable Energy Laboratory (NREL) of the U.S. Department of Energy proposed the weather-corrected performance ratio (PRcorr). This PRcorr index calculates the performance of the PV system which has taken the weather variations that influence the cell temperature into account. Both techniques were compared with the simulation program to analyze the PR index according to system conditions. The study site is the on-grid PV rooftop at Kasetsart University Chalermphakiat Sakon Nakhon (CSC). The PV panel is oriented to the southwest, 215 degrees azimuth. The angle of the inclination of the panel is 17 degrees. The result shows the trend of monthly PRcorr with little variations. At the same time, the PR value over the year has a lot of variations. The variation of PRcorr and PR is 2.39 and 5.07, respectively. PRcorr has low variability due to the correction of weather factors. The average cell temperature is an important variable. To calculate the average temperature of the panels, one year of data is needed to filter out distorted information. The system available condition is an important factor for the on-grid PV system at low voltage.

“…A system of solar tracking is an automatic control system on solar panels that detect sun motion to get optimal light intensity. To improve the performance of the solar tracking system, the angle of tilt and orientation of solar panels is set perpendicular to the direction of the sun's rays, aiming to produce an optimal amount of radiation each year (Singh et al, 2016). Solar tracker systems are classified into single-axis and dual-axis solar tracker systems.…”

Efisiensi yang rendah pada solar cell dipengaruhi oleh beberapa factor yaitu tingkat radiasi, suhu, dan sudut instalasi. Penelitian ini membahas upaya meningkatkan performa solar panel yaitu dengan menggunakan sistem pelacak surya sumbu tunggal. Dalam penelitian sistem pelacak surya sumbu tunggal ini dimodelkan dengan menggunakan PID controller pada software Matlab Simulink. Dalam metode tracking system, solar cell disimulasikan pada sumbu tunggal yang berorientasi pada sudut elevasi, sebagai masukan dan pengoptimasian kontrol posisi yang tepat terhadap arah pergerakan matahari pada pukul 07.00 -17.00 wib. Hasil simulasi didapatkan penggunan kontrol PID pada perancangan single axis solar tracking system menunjukkan hasil yang baik, dimana kontroler yang dirancang dapat mendeteksi arah pergerakan matahari dengan cukup akurat. Sudut elevasi terendah yaitu 1,7 derajat dan tertinggi 68,21 derajat. Solar tracking system memiliki potensi menyerap lebih banyak radiasi matahari untuk mendapatkan output lebih baik yang dihasilkan dari solar cell.

“…In this sense, two differentiated energy consumption periods can be found: no harvest, and harvest periods where the latter has a considerably higher load consumption. In Thailand a 50 kWp solar photovoltaic system may generate more than 75% energy due to different array tilt angles (β) and array orientation angles (α) [13]. Meanwhile, when tilt angle is fixed, almost 20% difference of generated energy from roof-integrated solar photovoltaic system was found when different orientation angles, +2 • and −87 • , were considered in the United Kingdom [14].…”

Impacts of Array Orientation and Tilt Angles for Photovoltaic Self-Sufficiency and Self-Consumption Indices in Olive Mills in Spain

et al. 2020

Olive mills are extensive in the Mediterranean Basin, and Spain constitutes approximately 45% of global production. The industrial sector faces a new energetic paradigm where distributed generation provided by small renewable energy sources may reduce the dependence from fossil energy sources as well as avoid energy distribution losses. Photovoltaic self-consumption systems can play an important role in confronting this challenge due to their modularity and their decreasing cost. Most of self-sufficiency energy studies are focused on building sector and discussions about the idiosyncrasy of industrial load profiles, and their matching capability with photovoltaic generation profiles can be scarcely found. This work analyzes the potential of photovoltaic self-consumption systems as a function of the array power, array tilt, and orientation angles to face the electric consumption in olive mills. Different recording intervals and reporting periods are considered. Results show that a self-sufficiency index of 40% may be achieved on olive harvest basis. Moreover, due to the load profile particularities, percentage error lower than 1.6% has been found when considering a recording interval of 60 min when matching the olive load consumption and photovoltaic generation profiles. Chosen array tilt and orientation angles may be key parameters to maximize the self-sufficiency index.
