UNICEF works in some of the world’s toughest places, to reach the world’s most disadvantaged children. To save their lives. To defend their rights. To help them fulfill their potential.
Across 190 countries and territories, we work for every child, everywhere, every day, to build a better world for everyone.
And we never give up.
How can you make a difference?
To develop system specifications for the solar PV water pumping system proposed to install in rural water supply systems in Sri Lanka.
Activities and Tasks:
- Detailed Initial Assessment
Area selection for the initial assessment: Three locations for the detailed assessment need to be decided based on the discussions with the engineers of the National Department of Community Water Supply. Visit the suggested locations for initial data and information collection: First conduct the assessment of the water supply systems in detail. During the initial assessment data and information on the following components of the water supply systems needs to be collected and assessed.
Considerations for designing a solar pumping system include various parameters such as water demand (volume), water storage, water depth (head), location of PV panels, and solar irradiance among others.
- Assessment of local conditions including climate, environment and social impacts.
- Comprehensive assessment of the energy requirement
- Water source
- Water demand (Daily water pumping Requirement),
- Water storage,
- Water depth (head),
- Treatment system
- Pumping system (Types, Positioning, capacity)
- Distribution system
- Delivery system
- Water supply system-related problems, risks, issues and challenges.
The total energy requirement needs to be collected based on the analysis of the whole water supply system through a detailed energy assessment. Further data and information will be collected on the required measurements mentioned below.
- Operation & control rooms
- Offices
- External lightening
- Space requirement for installation of solar panel and availability.
- Conduct the scenario Analysis
- Predict the demand and consumption needs through the analysis of past records of the evolvement of the needs of each site
- Develop a possible scenario for each site, based on the historical data and past records to meet the demand for power supply at each site
- The scenario development needs to incorporate the following aspects
- Present Energy Consumption
- Climatic and environment conditions of the selected 3 locations
- Present spatial requirements
- Selection criteria for different types of solar panels
- Comparison between different types of solar panels and comparison in terms of cost, efficiency availability in the market, appearance, advantages and disadvantages, particularly the impact to the surrounding environment
- Types of solar electricity generation systems (on-grid, off-grid, hybrid) most suitable to the selected locations
- Technical operational, and investment criteria for the solar system
- Recommendations for the best possible scenario.
Develop the detailed design and design specifications needed to cover the following aspects for each location.
The design life of the system must be minimum 25 years. System design should eliminate, as much as possible, the use of components with a short life, for example, batteries (typical life of 3-5 years).
Consultant needs to comprehensively assess the energy requirements of the selected (3) rural water supply schemes in selected locations. The consultant needs to develop relevant content and drawings as mentioned below.
- Single-line diagrams for all locations
- Sketches of all locations showing panels and structure
- Structure needs need to include the type of structure needed to tolerate wind, load and all other conditions,
- For the location the solar array should be tilted at a (specify degrees and azimuth angle).
- The mounting system,
- Detailed technical specifications
- BOQ of all solar system components,
- Wiring
- Connection points
- Net Metering (Metering of energy system)
- Devices for heat resistance
- Installation
- Required tests and certifications
- Greening options for the pilot project (during the construction, operation and maintenance phases of the project
- *Security measures and guidelines for the solar system to prevent theft or vandalism
- **Quality Assurance of the products
*Security measures: Recommendations for security measures and guidelines need to be provided considering the location, solar system and the local context.
** Quality Assurance of the products:
- Solar modules must be approved to IEC/EN 61215 and 61730 or UL 1703 certified and listed.
- All modules must be of a robust design.
- Control equipment must meet EN 61800-1, EN 61800-3, EN 60204-1 or internationally recognized equivalent standards
- Control equipment must provide diagnostic indicators and show status.
- The market is flooded with bad-quality solar modules. Cheap uncertified modules might drop their output only after a few months, making the system not meet water requirements.
The Report should consist following chapters
Chapter 01: Introduction
Chapter 02: Selected Scenario (Evidence Based)
Chapter 03: Design and Design Specifications
Chapter 04: Needs of the Electrical and Civil Works
Chapter 05: Solar Installation
Chapter 06: Capacity Estimation
V. Design tender documents for the implementation phase
- Prepare the Tender Package in coordination with UNICEF and the National Department of Community Water Supply to implement similar kinds of projects in the future. The Tender package will need to include the following annexures
- Terms of Reference (TOR)
- Technical specifications,
- Drawings
- B.O.Q
- Operations and Maintenance scope
- Provide recommendations for the necessary tests (e.g., tests for the roof).
- Develop the design as per specifications and validate the design
- Check-up summary to evaluate the tender documents
VI. Conduct meetings with the relevant sector partners
Present the Assessment Report, Design and Specifications to the existing technical working group comprised of UNICEF, the National Department of Community Water Supply, the National Water Supply and Drainage Board (NWS&DB) and the Water Resources Board. The consultant has to present progress, results of assessment and content of key deliverables at different stages through 3-4 meetings as required. UNICEF will facilitate and organize these meetings.
The consultant is expected to read, understand and adhere to the guidelines of the UNICEF Social and Environmental Sustainability Standards and Procedures (The draft will be shared after signing the consultancy agreement).
The consultant needs to review the following websites, materials and videos related to the solarization of water supply systems.
- https://globalwatercenter.org/solar-guide-access/
https://thesolarhub.org/about/
Videos in ENGLISH.
Selecting Quality panels, here.
- Preventing Theft of panels, here.
Work relationships: The national consultant will be under contract with UNICEF Sri Lanka and report to the Programme Officer (WASH & Climate Change) for contractual and logistical matters. For technical guidance and collaboration, the consultant will liaise with the UNICEF Programme Officers in different units and zonal offices as well as with the Government officials at national and sub-national levels.
