SOLAR SITE SURVEY ROOFTOP

  1. 1. SOLAR FEASIBILITY STUDY BY PREMKUMAR.E FOR ROOFTOP AND GROUND MOUNTED PROJECTS
  2. 2. Solar Feasibility Study ■ The first step in obtaining solar energy is having a solar feasibility study done. ■ It plays very important role while designing Solar PV System. ■ With the solar feasibility in hand, it is easier to prepare accurate Bill Of Material (BOM). ■ It is used to find out any problems associated with the project (and how to solve them).
  3. 3. Information to be collected during Site Survey ■ Site Physical Details – Reserved Roof space for Mounting Solar PV panels. – Type of Mounting System required ■ RCC Roof (Normal) ■ RCC Roof (Elevated) ■ Galvalume Sheet Mounted – Orientation of the Building (True South or With some Azimuth angle). – Tree shading and any other factors that will affect system production. – Height of the Building. – Exact Latitude & Longitude details.
  4. 4. RCC Roof Mounted (Normal) RCC Roof Mounted (Elevated)
  5. 5. Galvalume Sheet Roof Mounted
  6. 6. True South Orientation With Azimuth Angle
  7. 7. Structure Details ■ RCC Roof – Existing Pillar/Column Position. – Slab Thickness and Height of parapet wall ■ Galvalume Shed – Sheet Profile. – Existing Truss and Purlin details. – Turbo vents and Skylight Position.
  8. 8. Component Placement Details ■ Confirm Inverter Placement details with Client – It reflects in DC cable Loss & Cost. ■ Lightning Arrestor Placements ■ Earth pit Location – This Should be confirmed & Approved by Client. Measure the Cable Distance ■ Get the Exact Distance between Module Array & Inverter. ■ Cable Routing Confirmed by Client (From ACDB to Existing LT panel) ■ LA Down conductor length. ■ Earthing Cable Length from PV Array, Inverter to Earth pit
  9. 9. Electrical Details of the site ■ Interfacing Voltage Range – For Residential Purpose (1 Phase/3 phase) – For Commercial purpose (LT Voltage/HT Voltage) with Voltage Range. ■ Get Client Electrical SLD ( where we need interface) ■ Availability of Spare Feeder (to feed our generated solar energy) - If Not, Check Provision (Space) to place new spare feeder - Get the details about Spare feeder (Client Scope or Swelect Scope) ■ Existing DG Details (Make,Capacity, RPF Relay Availability) ■ Load Details – Base Load – Peak Load ■ Power Shedding Time (if any)
  10. 10. Sample Client Electrical SLD
  11. 11. LT Panel With Spare Feeder Provision for Spare
  12. 12. Load Curve
  13. 13. Ground Mount System ■ Site Geographical Coordinate (Latitude & Longitude) ■ Topographic Map/ Land Survey Details ■ Tree or any other Shadow Objects (Transmission tower) ■ Site Condition – Any rocks available ( Which makes MMS Foundation work complicated) – Land Levelling required or Not ? ( Scope of Land Levelling) ■ Soil Test Report ■ Interfacing Voltage Range (11KV/22KV/33KV) ■ Distance between nearby substation and Plant
