2. One Unit Saved= Two Units Generated

3. Proposals Roof top solar feeding supply directly to Switchgear
Roof top Solar feeding Power to DC Switchgear.
Roof top Solar feeding Power to H2 Generation Plant.
Power factor improvement of CHP HT feeders from Plant HT Switchgear 3

4. Proposals-1
Roof top Solar Power feeding to Switchgear (without Battery System)
415 V SERVICE SWGR
Normal Supply 4

5. Proposals-1
Switchyard Building + Service Building Stage-III Potential 50 Kwp
Tech Feasibility – asserted by REDG based on Roof Area and Sun intensity
Costing - 42Lacs
Yearly Saving -PLF(18%)*50=9KW (INR )
Pay back Period- 10 years Maintenance free as no battery requirement- Economical & Sustainable Solution
Proposed for Turbine floor / PT Plant as availability of Roof Space as well Switchgear loads. 5

8. Future Course of Action
Step-1 : Area assessment
Step-2 : Switchgear Identification
Step 3 : Tech Feasibility
Step 4 : Approval

11. Proposal-2 Roof top Solar Power Feeding directly to 220V DC Switchgear11

12. Proposal-2
Depending upon the intensity of Sun, PV Cells used to generate , Inverter stabilize the AC output by controlling the rectifier.
Here to control the DC voltage, solar charge controller is required, now manufactures are available (Vikram Solar , Moser Boer etc)
If proposal converted to reality then this would be the First Project ,solar directly charging the 220 DC Switchgear.

13. Proposal-2
Capacity( Switchyard DC DB) – 30KWp ( calculated as normal current 60A with 240 V)+ Roof space available
Costing – 20 lacs ( Budgetary offer of Vikram Solar)
Yearly Saving -PLF(18%)*30=5.4KW (INR )
Pay back Period-10 years Maintenance free as no battery requirement and invertors - Economical & Sustainable Solution.
VSTPP has a potential of 200KWp through this , If Automation system is included then approx 300KWp- Economy of Scale 13

14. Proposal-3
Roof top Solar Power Feeding directly to Hydrogen generation plant. 14

15. Proposal-3 Yearly Saving -PLF(18%)*30=5.4KW (INR 141912)
If proposal converted to reality then this would be the First Project ,solar directly being used for Hydrogen generation
Capacity – 30KWp ( calculated as normal current 500A with 60 V)+ Roof space + open space area available for solar panel.
Costing – 20lacs ( Budgetary offer of Vikram Solar)
Yearly Saving -PLF(18%)*30=5.4KW (INR )
Pay back Period-10 years Maintenance free as no battery requirement and invertors - Economical & Sustainable Solution. 15
