Techno economic analysis of using solar water heaters with evacuated tubes in Khartoum, Sudan
This paper presents the techno-economic study of using solar water heaters employing evacuated tubes in Khartoum, Sudan. Sudan experiences high solar irradiation and is thus a good candidate for harnessing solar energy. One direct application of solar energy is for domestic water heating application...

This paper presents the techno-economic study of using solar water heaters employing evacuated tubes in Khartoum, Sudan.
