Abstract

The invention discloses a roof type photovoltaic array pitch optimizing method based on shadow radiation analysis.The roof type photovoltaic array pitch optimizing method based on shadow radiation analysis comprises the steps that firstly, a building model and geographic position attributes of the building model are obtained; secondly, according to the geographic position attributes of the building model, a laying area of photovoltaic equipment is determined; thirdly, according to the geographic position attributes of the building model and parameters of the photovoltaic equipment, an installation pitch initial value of a photovoltaic array is calculated; fourthly, a static investment target function for unit electric energy is established; fifthly, the photovoltaic array pitch is adjusted to make the static investment of unit electric energy be minimum, and the photovoltaic array pitch with the minimum static investment of unit electric energy is the actual laying pitch of the photovoltaic equipment.By means of the optimizing method, more photovoltaic equipment is laid in a limited area by adjusting the photovoltaic array pitch, the total electricity generating amount is increased, and the static investment of unit electric energy is reduced.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a method for optimizing the spacing of rooftop photovoltaic arrays based on shadow radiation analysis. Background technique [0002] In order to reduce the energy consumption of buildings and promote the on-site use of photovoltaic new energy, researchers have proposed the idea of ​​photovoltaic building integration. By combining buildings with photovoltaics, buildings have changed from simple electricity consumers to electricity generation and utilization complexes. The integration of photovoltaics and buildings not only reduces the waste of land resources, but also generates electricity locally and consumes electricity locally, which greatly improves the utilization efficiency of photovoltaic power generation. [0003] The surface form of the building is complex, with different photovoltaic laying surfaces such as flat, vertical, and inclined surfaces. The calculation of...
