Call for expression of Interest for installation of 10 kW Solar power system

Kathmandu University School of Management is constructing new solar power system as secondary backup source of power of 10kW capacity. The construction will be done on roof top of KUSOM building located at BalkumariLalitpur.

In this regards, we would like to call expression of interest (EOI) from local companies for the design, installation and commission of solar power system with best available resources and technology.

Interested applicant should provide technical and financial details of the system along with EOI.

Technical proposal

  1. Designs should meet the minimum output detailed in technical specification.

  2. Proposals should outline all calculations, drawing and working which explain how their proposed design provides this output. This should justify the overall system design, and the selection of each component given the key design principles listed below.

  3. Detailed layout of PV installation and power management plan.
    • Installation work plan, timeline and management plan.
    • Operation and maintenance training requirements, schedule and plan, and any additional suggestions regarding the management of maintenance.

    • Last date of submission is 24 Dec 2015. 

    4. The proposals must state what the warranty period is for all components and what the operation and maintenance requirements are. Proposals should demonstrate that they have authorized service centres or repair centres for the technology they are providing.
