  20. 20. 1. the way in which the inverter performs the maximum power point tracking (MPPT), mean that modular configurations are not always the least susceptible to shade effects. 2. central-, string- and module-inverter configurations,``` 3.3 Inverter MPP track 3. Shading Treatment
  21. 21. 1. Elevation or Latitude Angle for preventive shading:/ • An important parameter in the design of photovoltaic systems is the maximum elevation angle, that is, the maximum height of the sun in the sky at a particular time of year. • This maximum elevation angle occurs at solar noon and depends on the latitude and declination angle as shown in the figure below
  22. 22. See my article: https://www.linkedin.com/pulse/cost-optimize-azimuth-angle-tilt-over- photovoltaic-solar-eyad-adnan/
  23. 23.  No cost optimizing can be achieved at hemisphere area by setting the azimuth angle to 180 "PV oriented to south orientation" and the hemisphere south the azimuth angle is 0.
  24. 24. • How much area we need to our project ?? -The required area for all PV nodules = total KWp/160 W I.e. each 160 wattage = 1 m2 @nominal cond - The required area for shading phenomena = 70 % of total area - The free area and equipment area = 30 % - Safety factor upon your economic issue 𝑇𝑜𝑡𝑎𝑙 𝑎𝑟𝑒𝑎 = 𝑡𝑜𝑡𝑎𝑙𝑘𝑤𝑝 160 ∗ 1.7 ∗ 1.3 -if the project is only one raw such as building roofs The shading and free area factors will be small
  25. 25. • Site Surveying is the first step for designing and installing PV grid • Average solar radiation, site latitude, sun elevation angle and shading effects should be investigated during site visit and assessment • Shading can be eliminated by free space between PV rows, PV bypass panels , tilt angle and MPP track in string inverters • Tilt angle of PV panel can determine by site latitude angle • Azimuth angle or PV orientation to south sun at northern hemisphere • Shading can be either uniform or non uniform shading
  26. 26. • No cost optimizing can be achieved at hemisphere area by setting the azimuth angle to 180 "PV oriented to south orientation" and the hemisphere south the azimuth angle is 0. • Tilt angle is fixed to your latitude building +15 in winter and -15 in summer; • the fixed tilt angle over year is the average angle between tilt angle in summer and winter
