In PV system the alternative in night or sun set is battery then I asked about other alternative of using battery like special salts?

Question

Battery is not good alternative as it increase pollution, expensive and need periodical maintenance more over it is limited capacity ,maintenance free battery is not recommended to use for open or desert area

Safi Ullah · Answer

For PV system battery is the best. For other system like wind there is no such need of batteries as alternatives.

Francesco Miconi · Answer

I believe that a more advantageous system is the accumulation system with the electric machinery that works when needed by a generator and a motor. In combination with a PV plant in the daytime, I produce energy and the excess is used to pump water into a higher basin, while at night it reverses the cycle and produces energy by emptying the raised basin formed during the day.

special salts!! as in some kind of Phase Change Materials (PCM)??

I don't think it's feasible because the energy that's stored in PCM is thermal energy, while the energy produced by PVs is electrical energy and the conversion would result energy losses.

Also in case you want to use the stored energy in it's electrical form, the conversion from thermal to electrical is not common at small temperature variations.

However PCM can be used in Solar Water Heaters to store excess heat during the day (Thermal Battery) in order to get hot water in the night without the need of a boiler.

Saif Al-khwaldeh · Answer

Hybrid systems maybe it's more likely to use than batteries , due to high periodic maintenance for batteries , comparing it with diesel generators

maen banihani · Answer

alternatives are hybrid system which uses wind and diesel power generation

Anuradha Pawar · Answer

Supercapacitor is other best option for storage in stead of battery

shady Nagy · Answer

you can using salt as csp systems

but i prefer using batteries

Abdullah Alruwaili · Answer

i prefer use battery or from the grid
