Is it feasible to replace my Photo Voltaic (PV) solar panels system by Solar Water Heater (SWH)?
Dear Issam Shabani ,
welcome!
The solar energy can be used in direct heating such as water heating and it can be used in electricity generation. Normally solar water heaters are more efficient and cost effective than the PV electric generation.
Conceptually, when you use PV to convert solar radiation into electricity the conversion efficiency is relatively low in the order of 15 percent.
The cost of the PV generators are relatively expensive because of the materials used are very expensive.
So, PV generated electricity is never used in heating except under very controlled conditions.
There is a concept which is never use PV for heating.
Simply because the direct heating is more efficient and more cost effective.
Best wishes
Totally different technologies. Differs in capital cost and running cost. I hope this helps you start your search: https://www.tileenergy.uk/difference-between-solar-photovoltaic-energy-and-solar-thermal-energy

Both converts the energy of the sun's radiation into another type of energy - thermal and electrical. The economic aspect is different everywhere and depends on many factors (prices). Install a water heater additionally, if finances permit.
These two have two different applications. Please have a look at this article:
