PhotoFlow system collects rainwater and generates electricity
For many developing countries, the supply of electricity and clean water is sporadic and of poor quality.
Looking to address this, South American-based design consultancy NOS has developed a two-in-one concept design that combines solar power generation with rainwater collection.
The PhotoFlow system is composed of eight identical triangular photovoltaic modules that are mounted on commercial or custom water tanks.
When assembled, these form an octagon with a slight slope of 3°, allowing water to funnel into the central filter. The water path then continues through a hose that directly goes into the water tank.
Each module is equipped with first-generation monocrystalline silicon solar cells covered with an anti-reflective adhesive which protects the photovoltaic semiconductor and minimises the loss of light through reflection.
The system integrates N-type and P-type silicon layers. On top of the outer layer of the glass, a Nano-repellent film is applied to prevent dirt from obstructing light.
Each module has a lid at the end to allow easy access for cleaning, maintenance and part replacement.
The water tank is made of recycled polyethylene through rotational moulding with a capacity of 400litres. The inner layer of the tank is covered with a coating that controls the formation of bacteria and fungi to maintain the quality of potable drinking water.
NOS is currently seeking funding for PhotoFlow, in the hope that one day it will supply homes in developing countries with these two vital resources.
