Langgewens Research Farm

A sustainable solar lighting solution that reduces the high electrical reticulation costs

Langgewens Research Farm is located between Malmesbury and Moorreesburg in the Swartland. Established in 1926, the farm’s purpose is to provide infrastructure and staff to support researchers. Research institutions currently involved in projects on the farm include the Western Cape Department of Agriculture, Stellenbosch University, ARC Small Grain Institute, Swartland Cereals Development Group and other private institutions.

The client needed a lighting solution installed along the road leading up the Langgewens Research Farm in Malmesbury. Due to the high costs that electrical reticulation would pose, it made sense to go the solar lighting route.


More light, less costs

Our BEKA SOLAR units were the LED solar lighting solution of choice. This solar streetlight for outdoor residential and public applications offers a full customizable option to suit all off-grid solar lighting requirements.

The BEKA SOLAR standard single streetlight with the ZIYA luminaire was chosen for this project. It provides a reliable lighting solution with a high Ingress Protection level that withstands high ambient temperatures and vandalism. The BEKA SOLAR is a sustainable off-grid performer with a superior lumen/watt ratio.

The photovoltaic energy conversion is optimized by efficient Polycrystalline solar module technology to maximise solar energy. This in turn offers the best energy storage options and autonomy available on the market with our range of battery options, namely Lead, Lithium and the new SuperCapacitor. This SuperCapacitor removes the depth of discharge (DOD) issues, and furthermore offers extended life and discharge cycles.

Controlling the whole system and using this solar energy by programming the Maximum Power Point Tracking (MPPT) charge controllers, it protects and optimizes the system from any internal and external factors, like thermal environmental changes when charging the batteries.

The BEKA SOLAR offers a renewable lighting solution to operate in any of our very challenging African environmental conditions.

We locally develop and manufacture energy-efficient LED lighting products, designed and suitable for local conditions.

We are very proud to be associated with the Western Cape Government in providing a successful LED solar lighting solution for this project.
