[Equest-users] 回复： Central PV system contribution to singlebuilding?

[赵永青]

Zara zhou's question is how to distribute a central PV generation to each building.However，all the answers are how to calculate PV generation.

Hi Zhouzarah,


I have done some calculations as per my understanding.
I have done certain assumptions like:
1.&#xA0; Solar PV area and&#xA0;
2.&#xA0; Number of months for solar insolation in India.
Insolation is nothing but the direct solar radiation energy per PV sq. meter per day.It can be over the ground surface &#xA0;also.
For India the average insolation can be from 4 to 6.5 kWh/ sq. meter/ day.
It varies from country to country.

Total solar energy generated as electricity per year = Solar insolation (kWh/ sq. meter/ day)X solar PV area X total number of days for proper solar insolation X efficiency of the the solar PV cell.
The efficiency of solar PV varies from 8 to 13 %age for mono crystalline to poly crystalline PV
Hence i have done the calculations.
Even IES-VE has the module to have the solar PV calculations.
This energy can be deducted from the proposed case energy&#xA0;consumption to have the savings.

Subject:&#xA0;[Equest-users] Central PV system contribution to single building&#x200F;
 Dear eQuesters,

I am working on a LEED certification for one building in an industry park. The park has a solar PV system serving several buildings. So I do not think I can simulate the PV systems directly in eQUEST to get its share to the LEED target building.&#xA0; My question is how to estimate the PV generated electricity to my building? Should I prorate the PV electricity based on those buildings' energy use, or there is a better way to do the calculation/estimation in the design phase? Any comment is appreciated!


Best regards,


Zarah
