Agri-PV System Design Consultancy

The International Water Management Institute (IWMI) is seeking a qualified consulting organization to undertake the Agri-PV System Design Consultancy under the SoLAR Phase II Project.

The selected consulting organization will support the development of agrivoltaics in Bangladesh by combining international engineering expertise with local hydro-agronomic knowledge.

The assignment includes conducting Agri-PV system simulations to optimize clean energy generation under Bangladesh’s solar irradiance conditions and developing calibrated crop growth models using empirical agronomic data, including photosynthetic light-response analysis of selected high-value vegetable crops under varying direct and diffuse light conditions.

Objectives of the Assignment

The consulting organization will:

1. Assess the technical feasibility of integrating Agri-PV systems with existing and new solar irrigation pump infrastructure in Bangladesh.
2. Optimize Agri-PV system designs through engineering simulations to maximize clean energy generation under local climatic conditions.
3. Evaluate crop performance under Agri-PV systems by developing calibrated crop growth models based on field-generated agronomic data and light-response analyses.
4. Provide technical recommendations for pilot implementation and scaling of Agri-PV systems, integrating engineering and agricultural considerations to support sustainable deployment in Bangladesh.

Duties and Responsibilities

The consulting organization will develop a comprehensive Agri-PV design package covering two pilot models in Bangladesh:

• Pilot 1: Retrofit of an existing multi-leg solar PV structure at the ESDO Gorgori site in Alamdanga.
• Pilot 2: Design of a new elevated monopole Agri-PV structure for a second ESDO site.

The assignment aims to identify technically feasible, agronomically suitable, and financially viable Agri-PV configurations that preserve the primary function of solar irrigation pump systems while enabling productive agricultural use beneath and around the solar arrays.

The consultancy will be structured around four interconnected work packages:

1. Agronomic Design Simulation
2. PV Layout and Energy Optimization
3. Structural Design and Engineering
4. Business Model and Scale-Up Inputs

These work packages will be implemented sequentially to ensure that agronomic requirements inform PV layout design, optimized layouts guide structural design, and the final technical configuration supports energy yield assessment, cost evaluation, and business model development.

Deliverables

The consulting organization will provide the following deliverables:

1. Inception Note and Design Basis - Summary of site data, assumptions, modelling approach, crop selection methodology, PV design parameters, and identified data gaps for both pilot sites.

2. Agronomic and Light Simulation Report - PAR modelling, seasonal light distribution analysis (Rabi, Kharif-I, and Kharif-II), crop suitability assessment, shading analysis, and recommended crop shortlist.

3. PV Layout and Energy Optimization Report - Optimized PV configurations, energy generation scenarios, irrigation-energy integration assessment, bifacial gain analysis, and layout comparisons.

4. Structural Design and Engineering Package - Retrofit design and structural modification package for Pilot 1, and detailed monopole design package for Pilot 2, including wind load analysis, foundation assessment, drawings, specifications, and reinforcement recommendations.

5. Business Model and Cost Inputs Note - Energy yield estimates, cost benchmarking for retrofit and new-build options, key cost drivers, and inputs for financial viability and scale-up assessments, including net-metering considerations.

6. Final Integrated Technical Report - A consolidated report covering agronomic analysis, PV layout optimization, energy performance, structural design, cost considerations, risks, and final recommendations for both pilot sites.
