Yes, Oswal Pumps is originally a Karnal-based solar pump manufacturing company. However, the company is now expanding. Its subsidiary, Oswal Solar Structures, has set up a module plant in Karnal, close to its solar pump unit. As per the latest ALMM of January, Oswal Solar Structures has a total enlisted solar module manufacturing capacity of 160 MW.

Solar cell manufacturing is inherently more complex than solar module production, which is largely an assembly-based process. The production of solar cells requires significantly higher capital investment at the outset. In India, the establishment of solar cell production facilities also involves navigating additional regulatory hurdles. This is due to the water usage during production and the disposal of effluents. Furthermore, the handling of ingots and wafers involves working with hazardous materials. As a result, apart from the capital requirements, solar cell manufacturing and related backward integration must comply with stricter environmental, pollution control, safety, and waste management regulations at the state level.

While cleaning solar modules with water first thing you should do is to use soft bristle cleaner or dedicated solar panel cleaning brushes. You need to also ensure that you do not use excessive water pressure. Excess water pressure can damage your solar panels leading to the development of microcracks. The maximum pressure that can be used for solar panel cleaning is 35 bars. You should also try to use soft water for cleaning solar modules.
