Updating a discontinued Mod.

Hi all, the modder Sigma 1202 has discontinued this mod modthesims.info/d/631669/functional-solar-panels-and-water-heater.html





Can someone give me guidance on how to update this mod to make it functional?
I only want to use it in my game.

I do not have Eco Lifestyle and really don't want that pack. I just want to make living off the grid easier, so they can have electricity and heated water. 

Thanks
