The method considers the frequency distribution of solar radiation over the year, and the indoor and outdoor solar radiation and PV power system testing are combined, which can provide an accurate assessment of the annual power generation and power generation efficiency of PV panels. 2. Materials and methods 2.1. Research ideas
A new method for evaluating the power generation and generation efficiency of solar photovoltaic system is proposed in this paper. Through the combination of indoor and outdoor solar radiation and photovoltaic power generation system test, the method is applied and validated. The following conclusions are drawn from this research.
To study the distribution of regional solar resources in detail, photovoltaic modules must be placed in the sun for a long time to receive exposure, and long-term continuous testing is performed to calculate the actual power generation, which is obviously difficult.
The present photovoltaic (PV) power generation systems are globally facing the irregularity problem in the distribution of PV generation. In particular, the exact PV power forecasting is critical for grid-connected photovoltaic (PV) systems under unwanted changes in environmental circumstances.
Feature selection for time series algorithms is based on different seasons and climate changes. PV power generation forecasting by different AI models has carried out on an hourly basis to test efficacy. LSTM model shows the lowest error rate for quick PV power generation forecasting.
Furthermore, the collected PV data on various variables (temperature, sunlight, insolation, clouds (total cloudiness, low-middle cloudiness, minimum cloud height), fine dust ( [Particulate Matter (PM)] or PM10), precipitation, snow cover)) were used and analyzed in 3 methods (month, seasons, revised season affected by global warming).
