Rice sprout transplanter is widely used in agricultural countries especially in South East Asia area because it reduces human error and increases productivity. Rice seeds are placed in a seeding tray for 1–2 days and transplanted into the rice field by a transplanter. Parachute Rice Sprout Transplantation is a new method for the rice transplantation which increases rice sprout growing rate and decreases...
This paper presented performance analysis of solar cells and PVSYST simulation software of polycrystalline silicon and thin film amorphous silicon solar cells under Thailand conditions. The results indicated that performance result based on IEC 61724 standards (Photovoltaic System Performance Monitoring-Guidelines for Measurement, Data Exchange and Analysis) [1] found the average net energy from array...
The outdoor performance of photovoltaic (PV) modules is affected by several environmental conditions. Spectral irradiance is one of the important factors that should be investigated. This paper presented the effect of spectral irradiance by using average photon energy (APE) to declare spectral irradiance distribution. The relation between the outdoor performance (PR) and the APE were shown. The results...
This study aimed to focus on the outdoor performance ratio (PR) and the relationship between PR, module temperature and irradiance for (a-Si) and polycrystalline silicon (poly-Si) located in Thailand. The result of this study revealed that the PR of a-Si increased during the summer and reached the highest value in the rainy season. For a 3-year period investigation, average PR of a-Si showed higher...
