The overall plan and priority construction size of the installation capacity shall combine with the long-term development planning, equipment load capacity of the near term should be used as the main capacity of the solar-cell-array and civil construction facilities should combine with long-term planning.
1.0.8 Any thing un-specified in this specification shall be carried out according to relevant national standards.
2 General Requirements of Solar Photovoltaic Power System
2.0.1 The solar-cell-array (hereafter referred to as array) shall be set on a safe and reliable place free from shielding obstructions, pollution sources (such as smog, dust) and corrosive gases.
2.0.2 In the normal condition, plane of the array shall face to the due south. If restricted by geographic conditions and surrounding environment or due to the meteorological conditions, plane of the array shall deflect a proper angle, which is smaller than the local geographical latitude eastwards or westwards.
2.0.3 The place where an annual average insulation duration is more than 1800h may use solar photovoltaic power system as the only power supply.
2.0.4 Solar photovoltaic power generating system may be used within the surrounding temperature rang of -40℃~+60℃ and appropriate products shall be used for the solar module in the severe cold areas or the areas with high temperature.
2.0.5 Reinforcement measures shall be taken in the area with array installation point where the local maximum wind levelis greater than Level 10.
2.0.6 Protection facilities, such as enclosures or handrails shall be used for the ground or the array periphery on the roof.
2.0.7 The solar photovoltaic power system shall have overvoltage protection measures and set with lightning-protection devices.
