Issahaku Walaman-i, a brilliant final year student at Ashesi University in Ghana has, as his final year project, built an innovative device that keeps solar panels clean without any direct human intervention.

A publication by Ashesi University indicates that by the time Issahaku Walaman-i enrolled at Ashesi as an Engineering student, the university had installed 720 solar panels across roofs on campus.

During his time on campus, Issahaku noticed that dust accumulated quickly on the university's solar panels during dry seasons and therefore dedicated his senior year project to building a device that could be deployed to clean solar panels automatically.

How the self-cleaning solar device works

The solar panel cleaning device consists of a casing, a rotating cleaning brush, and a sprinkler setup connected to a water source, all of which work together to perform a to-and-fro motion that helps clean the dust on the surface of the panel.

Aside from reducing the risk of climbing to manually clean solar panels and also the accumulated cost of hiring manual cleaners, Issahaku explained the problem his innovation solves in the words:

When the dust settles on the surface of the solar panels, it reduces the amount of sunlight that reaches the panel and consequentially, the amount of power and efficiency of the panel is also reduced.

Social media comments

Paul Gyen Juniors commented:

Wondering if the device itself is solar-powered. And also wondering: if a building roof is already full of solar panels, it'd need to be redesigned for this new device to fit.

Nana Kwame Yeboah indicated:

Brilliant idea. Good start. Going forward, the dust should not pollute the area. Otherwise, other panels will become dirty as a result of the cleaning process. A dust collection bag and suction system can be attached. Great effort. Keep improving it.

In a separate story, an innovative Ghanaian student, Eyram Tamakloe, has developed a portable monitoring device and dosage counter that could help asthmatic children better recognize triggers.

Besides discerning triggers in their environment, the devices could also alert the user to urgently retrieve a rescue inhaler.

Drawing inspiration from her childhood inadequacies

Tamakloe, a final-year student at Ashesi University in Ghana was inspired to build the devices for her final year project because of her childhood inadequacies as a person who suffered from asthma.
