  13. 13. Partners of the Project Government  Sources necessary fund for the program  Creates incentives (waiver of duties, tax benefits etc.) IDCOL  Provides grants to POs to reduce SHS cost and capacity building  Soft loan to PO  Technical assistance (training, logistics and promotional supports) Donor Agencies [WB(IDA), GEF, KfW, GIZ, ADB, IDB]  Provides grants and soft loans through IDCOL  Technical assistance to the program Partner Organization (PO)  Select Areas and customers and install SHS  Extend micro credit to customers  provide after sales services Manufacturer / Suppliers  Sell SHS or its components to POs Professionals  Technical specification and impact assessment
  14. 14. Committees PO Selection Committee  Consists of representatives from IDCOL and relevant government ministry and organization  Select POs to implement the program on the basis of micro finance experience, financial and technical strength Technical Standard Committee (TSC)  Consists of experts from University, Engineering department of government and IDCOL  Determines technical standards, reviews product  Credentials of dealers and approves the eligible equipment Operations committee  Consists of program in charge from all POs and representatives from IDCOL  Looks after the operational aspects of the program
  15. 15. AuditsIDCOL appoints independent organizations to conduct twotypes of audit:(i) Financial audit The objective of the financial audit is to ensure that the households’ down payments are accounted for properly and POs are utilizing the grants and refinancing for their intended purposes only.(ii) Technical audit The technical audit is conducted to ensure that only TSC approved equipment with their committed quality are used under the program. Representatives of the PO and suppliers accompany the technical audit team.
  16. 16. TrainingsPO personnelTo build awareness and capacity building among the staff ofthe POs’ and the consumers.Topics: SHS configuration, positioning of SHS, installationprocedure and guidelines with measurements, maintenanceand troubleshooting of SHS and batteries, guidelines formonitoring and inspection of SHS, marketdevelopment, micro-credit methods for marketing.Cost: 80% of the total expense is sponsored by IDCOL andthe rest is shared by the POs.For ConsumerSince SHS is entirely new to the households, consumertrainings are conducted regularly to educate them. They aretrained on how to use the SHS and fix petty problems withoutwaiting for the technician.
  17. 17. Other supportsFollowing supports are extended to POs by IDCOL:i) Logistic support: Each PO is given a computer for efficientdocumentation related to SHS installation. They are provided withtool boxes, motorcycle, demonstration kit, hydrometers and batterychargers for rendering better service to customers. Major share of thecosts is sponsored by IDCOL.ii) Promotional support: distribute publicity materials to raiseawareness and popularize the use of SHS in different parts of thecountry. Posters, leaflets, T-shirts, and billboards are distributed tothe POs for wider publicity of solar energy. TV and radioadvertisement are also developed and aired.iii) Exposure visit: To experience with the diversified uses of the PVsystems and other RETs, visits to other countries are also organizedboth for PO representatives and IDCOL staffs.
  18. 18. Development Impacts Provides illumination to rural areas. Increases income generating activities e.g. working hours have been increased for small businessmen, weavers, tailors, hair dressers, and handicraft makers. Students are getting benefits through extended hour of studies at night. The use of TV and radio has enhanced rural people’s access to the outer world. Study found that many women are feeling more secured at night after installation of SHS.
