Pondera

Pondera Consult was founded in 2007. We contribute with our clients to sustainable solutions to energy, climate and environmental issues. This includes large and small projects in the field of solar energy and onshore and offshore wind energy, hydrogen and energy storage. Pondera provides advice on how floating solar parks can be developed in Indonesia. There is still limited research on how the yield assessment (electricity output) differs from land-based solar parks.

What will you do?

In this (graduation) internship, you will delve into the yield assessment of ‘floating solar’, how the design of floating solar can be optimized, and which system is best suited for installation in Indonesia (potentially through a case study).

For the yield assessment, there are several challenges to consider:

• different angles of the panels;
• influence of waves on production, as short variations in angle might reduce system output;
• impact of water, which affects the ambient temperature;
• how to account for radiation through reflection from the water in the calculations.

Yield assessments are often conducted with paid software packages for subsidy applications. However, within the open-source environment of the Python programming language, there is also the possibility to perform a Solar Resource Assessment (SRA). Through the Python environment, all variables can be adjusted, such as solar radiation, shading calculations, and PV specifications. What is the difference in the yield assessment for floating solar systems when conducted with paid software versus open-source software? A sensitivity analysis can be performed regarding solar radiation data and the reference period for this purpose.

Additionally, it would be beneficial to conduct a sensitivity analysis concerning solar radiation data and the reference period. This is dynamic over a longer period. A sub-question could be what to use as a reference for your yield assessment when there is a clear dynamic trend in your solar radiation?

What do we offer?

• Flexible start dates; you can start any time.
• Flexible duration; we are happy to agree on the length of the internship together.
• Workspace at our office, directly next to Arnhem Central Station, offering the opportunity to experience daily life at Pondera.
• Good internship compensation.
• Personal guidance from one or more of our advisors.

Of course, the (graduation) internship can be adjusted according to the requirements of your HBO or WO educational institution.
