The estimate of the electric demand：
|
At ordinary times：
|
Emergency：
|
|
115KwH/d ; 770 people's power consumption
|
83.2KwH/d; 500 people's power consumption

|
The estimate of the Mould-Group area：
*The intensity of sunshine: 1Kw/m2 ：1Kw/m2
*the sunshine time：3.84H/d
*the efficiency of the Mould-Group：12%
|
The electric demands ÷(the intensity of sunshine × the sunshine time × the efficiency of the Mould-Group × the omprehensive coefficient)
|
|
The comprehensive coefficient: temperature changes, defilement, line loss , inverter efficiency + battery charge-discharge and compensation
|
|
At ordinary times： 0.65~0.8
|
Emergency： 0.57
|
|
115KwH/d÷1Kw/m2÷3.84H/d÷12﹪÷0.75＝332 m2
|
83.2KwH/d÷1Kw/m2÷3.84H/d÷12﹪÷0.57＝317 m2
|
|
↓
Take Max 332 m2. Only supply for emergent using, take 317 m2
|
|
Calculate the capacity of the installation：
|
the capacity of the installation of the solar power energy system ＝ the square measure of installation × the intensity of sunshine × the efficiency of the Mould-Group
|
|
332m2×1Kw/m2×12﹪＝39.8Kw≒40Kw
|
|
↓
|
|
The generation of calculation：
|
The generation of the solar power energy system ＝ the capacity of the installation × the sunshine time × the comprehensive coefficient
|
|
At ordinary times：
0Kw×3.84H/d×0.75＝115.2wH/d
|
Emergency：
40kw×3.84H/d×0.57＝87.5KwH/d

|
Whether it comforms the calculation of the electric demands or not?
|
|
↓ Yes
|
|
Carry on the design of the array of template and the capacity of battery
