What type of PCM (and if you know what substance exactly), other than paraffin, do you consider to use behind of the solar panels to increase efficiency?
In this case "PRICE" is very important and Paraffin is much more expensive than the others.

Thank you Himdri
but you probably did not understand the question
I mean the introduction of a series of other phase change materials except paraffin for thermal energy storage.
paraffin: there are many available options, but price is high. Also, fatty acids such as myristic acid (54degC) or palmitic acid (62 degC) are a good option too with high latent heat for both
Thanks for your response Rami
Which fatty acids have high latent heat and melting temperatures range from 30 to 35 degrees Celsius?
fatty acids, 30 to 35, you could go with Decanoic acid, transition temperature is between 32-34 degC based on purity (higher purity >99% the 34degC, lower purity
