Multi-factor photovoltaic equipment optimized laying method based on shadow radiation analysis

Abstract

The invention discloses a multi-factor photovoltaic equipment optimized laying method based on shadow radiation analysis. The multi-factor photovoltaic equipment optimized laying method based on shadow radiation analysis comprise the following steps of: acquiring building information; according to the building information, carrying out shadow radiation analysis on a building surface so as to obtain a region in the building surface, where photovoltaic equipment can be laid out; selecting one set of photovoltaic equipment laying parameters to complete a laying scheme; evaluating the scheme; and repeating completion and evaluation of the laying scheme until an optimal laying scheme is obtained. According to the invention, under the condition of considering illumination, a weather factor, laying conditions, line loss, roof rent, reconstruction cost, a building appearance factor and the like in the design process of a photovoltaic system, mounting parameters of a photovoltaic module are determined; and the photovoltaic power generation equipment optimized laying method which is based on shadow radiation analysis of a building model and uses minimum unit electric energy static investment as the target is disclosed.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a method for optimal laying of multi-factor photovoltaic equipment 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, the building has changed from a simple electricity consumer in the past to a power generation and electricity complex. The integration of photovoltaics and buildings not only reduces the waste of land resources, but also generates electricity and uses electricity locally, greatly improving the utilization efficiency of photovoltaic power generation. The specific application forms of photovoltaics in buildings include: photovoltaic roofs, photovoltaic tiles, photovoltaic curtain walls, photovoltaic sunshades, photovolt...

AI Technical Summary

Problems solved by technology

This method uses the solution of the predefined table, and the table data is the generalized data of the irradiation amount of the regular site, which cannot be adapted to the optimal laying of photovoltaics on the irregular site.

At the same time, the plan does not take factors such as the rent of the laying area and the cost of renovation into account, and it is difficult to support the optimal laying of photovoltaic equipment under multiple influencing factors
