Introduction
Solar energy as an important renewable energy, energy development and utilization, adjusting energy structure, protect the environment, respond to climate change
, And promote the sustainable development of society is important.
China's solar energy resource assessment in the relevant literature and in practice, there are many different solar energy resources (total radiation) classification index
And methods, resulting in solar energy resources (total radiation) evaluation findings are inconsistent, is not conducive to the formation of our solar energy resources objective and accurate understanding.
To meet the needs of solar energy resources development and utilization of solar energy resources norms (global radiation) evaluation standard is formulated.
Ratings total solar radiation resources
1 Scope
This standard specifies the solar energy resources (total radiation) grade division.
This standard applies to solar energy resource assessment and zoning.

3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Total radiation globalradiation
PYRANOMETER globalsolarradiation
Receiving from the horizontal plane above the 2π solid angle to direct and diffuse radiation sum.
3.2
Direct radiation directradiation
Direct insolation directsolarradiation; beamsolarradiation
Radiation emitted from the inner surface of the day in and around a small solid angle.
Note. In general, the direct radiation from the viewing angle of about 5 ° measured instrument. Thus, it includes part of the scattered radiation around the solar surface, which ring solar radiation, and
Japan faces its own viewing angle of only about 0.5 °.
3.3
Method to direct radiation directnormalradiation
DN
And the sun's rays on a plane perpendicular to the received direct radiation.
Note. From the terms of the values \u200b\u200bof direct radiation and the normal direct radiation is the same; the difference is that direct radiation is emitted by the sun and from the perspective of the definition of law
It is defined from the perspective of the receiving surface to the direct radiation. In the field of solar energy resources, the common law to direct radiation of the term to distinguish the horizontal plane
Direct radiation.
3.4
Horizontal direct radiation directhorizontalradiation
Horizontal direct insolation directhorizontalsolarradiation
DH
Horizontal plane to direct radiation received.
Note. The level of direct radiation and the normal relationship between the direct radiation is. DH = DN · sinh = DN · cosθz
Where DH is the horizontal direct radiation, DN for the law to direct radiation, h is the solar elevation angle, θz for the solar zenith angle.
