How can I store solar/wind energy in gravity or potential energy?

if have 2 large ponds @ different elevations, pump water lower pond upper pond , draw power through micro-hydro. weights not store lot of energy, need handle large amount of mass.

i want suggestion on system design store wind or solar energy directly gravity run house. on example gravity based light, want run heavy loads. how can build , calculate based on 1000 watts home requirements.
suggenstion on system design highly appreciated.
