This work aims to enhance productivity and reduce the production cost of conical solar distillers using green inexpensive materials. Conical stills are characterized by their cover is always exposed same radiation in all locations do not create shading. Different graphite bars installed at various distances still basin, acting as corrugated surfaces energy storage materials increase interface area, losses, overall performance. Three were designed tested investigate effect changing (0 30 mm) between rods on rate climatic conditions El Oued, Algeria. Furthermore, energy, exergy, economic, exergoeconomic approaches conducted assess viability proposed distillers. Results showed that reducing increases due increased interfacial space with basin water excess heat absorbed during day. The exergy efficiencies incorporated improved 46.23–90.46 % 181–321 respectively, compared traditional still. Based exergo-economic approach, annual outlets 45.65–90.46 187.5–439 yield payback period decreased 40.41–74.91 28.8–42.8 Finally, represent a good option for obtaining high performance economic benefit.
