technical installation conditions

Choi steel roof:

● Choi steel version is suitable for installation of photovoltaic stents; 
● Low choi steel roof structure bearing capacity up to 20 kg / ㎡, such as roofing did not meet the requirements of bearing capacity, the original structure reinforcement of photovoltaic modules of the reentry after installation; 
● The overall structure of the building low not seriously affect the deformation of the construction safety and corrosion; 
● Choi steel no serious rust, leak and damage, use fixed number of year has no more than 3 years. 


Concrete roof

● Concrete roof structure bearing capacity of 40 kg / ㎡. Such as roofing did not meet the requirements of bearing capacity, the original structure reinforcement of photovoltaic modules of the reentry after installation; 
● The overall structure of the building low not seriously affect the safety of buildings deformation; 
● Roofing waterproof layer not subjected to serious damage, no leak, otherwise need to redo the waterproof. 


Tile roof roof 

● Tile roof tiles need to uncover so that in the lower part of the fixed bracket system, asphalt tile can be directly after the punch to fill do waterproof; 
● Low tile roof structure bearing capacity of 40 kg / ㎡; 
● The overall structure of the building low not seriously affect the safety of buildings deformation; 
● Low quality daylighting roof (south, east, west) available area laid components of photovoltaic equipment to meet the minimum performance requirements for photovoltaic phalanx. 



The ground station 

● Towards appropriate for the flat areas or low gradient area from north to south. 
● Away from the bad geological area; 
● To choose the higher ground, away from the inner area. 


Grid pv systems installed capacity in principle should not exceed 25% of the superiors and branch transformer capacity, the photovoltaic array shoulds not be too far away from and branch and should as far as possible away from dust, high temperature gas, corrosive gas, surrounded by tall trees, shade building on its shadow. (depending on the scene the case may be) 


commercial installation conditions 

● Companies operating in a stable condition, good financial data 
● Enterprise property rights clear, roof use rights shall be owned by the enterprises themselves 
● Low electricity price for the enterprise, the more expensive, photovoltaic power generation system of the higher returns 
● Low power consumption big business day, and annual electricity consumption is relatively stable
