Conventional solar still productivity depends almost exclusively on incident solar energy, varying year round, hence much less productivity is expected in winter months. In this article, the use of thermoelectric modules is tested in order to compensate for productivity loss of solar stills in colder months as well as enhancing it in months of high solar energy availability. A solar still utilizing thermoelectric modules (Peltier effect) in tandem with an external reservoir was evaluated to increase levels of distilled water productivity by controlling the operation variables and its productivity was compared to a conventional solar still. The cold side of each module was installed in an interior wall of the solar still to increase condensation surface while the hot side was used to simultaneously preheat the brackish water of the external reservoir. For comparative analysis, data of solar intensity, ambient temperature, wind speed, distilled water productivity and temperature of critical components were periodically recorded. Daily cumulative yield of the tested solar still was 10% higher than conventional solar still following a modified input power scheme suggested by Al-Madhhachi & Min (2018). The experimental results were in good agreement with the simulated theoretical results
