SER (Resilient Energy Systems)

Design specifications include elements for the drinking water unit, electric power and thermal energy unit. The drinking water unit is composed of a 27 litres water tank, a 7-stage filtering system and an electric pump. The electric power unit comprehends solar panels with a nominal power of 36 W, a battery (12 V, 33 A) and a regulator (500 W to 220 V, 6 sockets; 60 W to 12 V, 1 socket; 6 W to 5 V, 1 USB port). The thermal energy unit is composed of a solar thermal collector with an on/off valve and an electrical resistance. It has a 360 W electric stove.

The electric power unit can carry solar panels of up to 300 W and could provide internet to the rural schools.

One SER system weighs 50 kgs and package dimensions for shipping are 1.50 (height) x 0.5 x 0.5 m.

As it is a plug-and-play installation no technical formation is required, however, for further support contact the manufacturer.

Expected minimum 15 years without replacement.^{Interview with representative}

The SER’s drinking water unit purifies 10,000 L/day of water, providing 4.5 litres per person each day. The water system reuses up to 66% of the water and the generated chlorine is used at a rate of 1 drop=1 litre of water. One SER system can charge up to 18 notebooks and phones per day and heat ambient-temperature 27 litres of water to 55ºC in hours with the solar thermal collector. A litre of water can be boiled in the electric stove within 10 minutes and the electric stove maintains cooking temperature for 20 minutes once turned off.^{Interview with representative}
