The stills below were developed in order to assess how to make the stills cheaper looking for local materials. in 2014 the focus was to test the water production. For 2015, a new M.Sc. Student from Oslo, Norway Halvard Kopperdal ,joined NCA/ Norplan team to followed up last year work. On this page photos of the different units are shown with some short comments about type and preliminary results.

**Refined Design** .Date: 10th May 2015

New design with plastic tray for prevent leakages, black painted glass above tray, insulation ( as can be seen) Back door for cleaning and emptying. Glass place sealed with silicone. Ready for testing.

**First Set of Prototype of Solar Still by Halvard in 2014** by : March 14

2.1 GI 17° single sloped solar still: 1000 mm x 800 mm, bended GI sheet, inclination of 17°. . Output ranged from 2-2.3 l/m2

**Solar still: Wood with GI lining**

**Still: Still with imported plastic lining**

**Still: Glass lining, gluing on gutter to collect condensate**

**Stills: Top fitted**

**Still Monitoring radiation and temperatures**

Plywood 20° single sloped Solar still: 1900 mm x 800 mm. output: 2.3-2.8 l/m2.

Testing arrangemetns for single sloped solar still: 1000 mm x 800 mm.. Halvard Kopperdal (M.Sc. student inspecting the design)
