Abstract: The factors influencing on the design of solar photovoltaic power station were analyzed, which include the output characteristics of the photovoltaic power generation, the power generation characteristics of the solar photovoltaic power station under different weather conditions, the relation between the solar irradiance data and the power generation, the relation between the power generation and the angle between the photovoltaic cell panels and the ground, the relation between the total annual power generation and the occupied area and the occupied area by unit area of the photovoltaic cell panel and so on. The total annual power generation calculation method was adopted to determine the angle between the photovoltaic cell panel and the ground, the influence of the surface cleanness factor of solar cell panels on the power generation was considered，the matters needing attention in construction of the solar photovoltaic power station were put forward.

Key words: solar photovoltaic power station, solar photovoltaic cell, solar irradiance, total annual power generation, surface cleanness factor of solar cell panel
