Problems solved by technology

In the existing industry research, the focus is on the voltage-current curve, power-voltage curve, etc. of photovoltaic cells. These curves are often obtained through simulation. These curves cannot reflect the power generation ability of solar photovoltaic cells in real time, and cannot Instruct users to reasonably arrange the use time of electrical appliances and maximize the use of solar energy
[0004] Solar photovoltaic power generation capacity is restricted by temperature and light intensity. If the power generation curve (P-t curve) and cumulative power generation (electric energy generated by photovoltaic cells) of solar photovoltaic cells can be predicted in a day, then users can According to the P-t curve and power generation, the use time of electrical appliances is reasonably arranged to maximize the use of solar power and reduce the cost of electricity. At present, there is no such prediction system and method
