| Abstract: |
| 【Objective】This study explored the practical application and development potential of the photovoltaic solar greenhouse to improve the design of photovoltaic solar greenhouse.【Method】The components of the photovoltaic power generation system were introduced using a 2 kW photovoltaic solar greenhouse in Yangling as an example.The generation capacity of entire photovoltaic power generation system was monitored using a C based monitoring software.The correlation between total outside solar radiation obtained by a solar radiation collecting instrument and the system generation capacity was analyzed using Excel.【Result】The generating power of photovoltaic power generation system in January was 0.618 kW with the maximum daily generating capacity of 9.544 kW·h and the minimum value of 1.414 kW·h.Generating capacity and total solar radiation had a significantly positive correlation,and the correlation coefficient in sunny days was greater than in cloudy days.【Conclusion】The 2 kW photovoltaic power generation system could provide electricity for environmental regulation of a greenhouse with an area of 500 m2.This study also provided the theoretical calculation method for capacity of the photovoltaic solar greenhouse. |
