*''A solar PV layout and sizing tool'': Residential solar PV is rapidly being deployed on rooftops around the world. In prior [https://svr-sk818-web.cl.cam.ac.uk/keshav/wiki/images/8/8b/Sizing_multiple_roofs-5_copy.pdf work] we have studied the sizing of solar and storage (i.e. how many panels and how much storage to purchase) to meet a certain level of grid independence. We have also looked at optimal placement of panels on sloping roofs. This work, however, does not apply to flat roofs, where self-shading between rows of panels is a problem. The goal of this project is to come up with optimal algorithms/heuristics for placement of panels on flat roofs, subject to self-shading and shading from both roof elements, such as satellite dishes and soffits, and nearby trees.
 
  
 
* ''3D wind velocity field and CO2 sensing'': [https://www.fondriest.com/news/researchers-measure-carbon-dioxide-exchange-between-forests-and-atmosphere.htm Flux towers] are used to measure the exchange of carbon dioxide between the atmosphere and the biosphere. These are typically very expensive.  At their heart, they have a CO2 sensor and a 3D wind velocity field sensor. These days, both can be built using off-the-shelf components, such as this [https://sensirion.com/products/product-categories/co2/ CO2 sensor] and this [https://docs.px4.io/main/en/sensor/airspeed_tfslot.html airspeed sensor], with three airspeed sensors place on orthogonal axes. This means we can put together a quick-and-dirty flux tower for well under £200 (as opposed to the £80K they charge now). We can also get access to a flux tower near Ely to compare the measurements from a top-of-the-line system to something less expensive. The goal of this project would be to build, deploy, and calibrate this sensing platform.

Part II/ACS projects (2024)

  • 3D wind velocity field and CO2 sensing: Flux towers are used to measure the exchange of carbon dioxide between the atmosphere and the biosphere. These are typically very expensive. At their heart, they have a CO2 sensor and a 3D wind velocity field sensor. These days, both can be built using off-the-shelf components, such as this CO2 sensor and this airspeed sensor, with three airspeed sensors place on orthogonal axes. This means we can put together a quick-and-dirty flux tower for well under £200 (as opposed to the £80K they charge now). We can also get access to a flux tower near Ely to compare the measurements from a top-of-the-line system to something less expensive. The goal of this project would be to build, deploy, and calibrate this sensing platform.
