Solar Water Heater

Solar for Tourism


Everyone knows that Nepal government's investment in R&D for R&D based economy is negligible. I had been trying several funding agencies such as Ministry of S&T, UGC, Nepal and The World Academy of Science and so on. I succeeded to get funding from some of these institution and built some very preliminary foundation for this research. I came to know through interview of Mahabir Pun Dai that NIC is supporting the novel ideas! which encouraged me to approach and build a collaborative partnership between NIC and Kathmandu university (KU). As a first step of collaboration between KU and NIC, I have initiated this project in which the grant was used just to purchase the materials and tools required for the project.


To quantify the relative thermal performances (efficiency and stability) between black nickel substrate and black paint based solar thermal collectors.

Key Features

As our product has better water heating capacity, it is more appropriate for hotels which require large amount of water. Because of permanent coating, our product is highly stable and requires very minimal maintenance compared to traditional home-made technology.
