What is PD IEC TR 63149- Photovoltaic (PV) farms about?
PD IEC TR 63149 is aimed at building mathematical models for the calculation of the distance between arrays, to farthest avoid shading and reasonably reduce the land usage of PV farms.
The key factor to affect land usage of PV plants is the distance between PV arrays. On the day of the winter solstice, there will be the most south-north shade. The boundary condition used in PD IEC TR 63149 to compute the south-north (S-N) distance between PV arrays is based on the winter solstice. When the sun is in the east, the longest east-west (E-W) shadowing occurs. The formulas are all the same, however, the users can adjust the boundary conditions based on local situations.
The no-shading calculation model is different for fixed PV arrays and PV systems with solar trackers. PD IEC TR 63149 provides mathematical models for both fixed PV arrays and solar trackers.
Who is PD IEC TR 63149- PV farms for?
PD IEC TR 63149 on PV farms is relevant to:
- Solar energy engineering industry
- PV module manufacturers
- PV power system manufacturers
- Product design engineers
Why should you use PD IEC TR 63149- Photovoltaic (PV) farms?
Rooftops, industrial areas, brownfields, degraded land, and marginal agriculture can all be used as lands for PV farms. In this regard, it is important to calculate land usage correctly in order to make the best use of available space.
PD IEC TR 63149 is helpful for only for the distance between PV arrays, but the formula can also be used to calculate the no-shading distance between the objects and PV arrays. The no-shading distance calculation is based on the northern hemisphere in PD IEC TR 63149, but all formulas can also be used for the southern hemisphere.
PD IEC TR 63149 can help you design land usage of PV farms effectively and prevent the loss of power generation because of shading between arrays.
PD IEC TR 63149 provides you with a simple calculation for a quick guideline of the land usage of photovoltaic farms for accurate and optimum land usage design.
