The best way to store the energy is to pump it back into the national grid taking advantage of government subsidies to effectively offeset your normal usage. Therefore you energy is used by someone else but you get the benefits... You may even be able to apply for a local authority grant to offset the additional costs - not sure if you could stretch it to a custom built frame as this would be more efficiant for energy production though....
New regulation coming in next year will also mean you get money fo the amount of generation you have regardless of how much you produce back to the grid to incentivise people to invest in microgen
