A home powered by solar panels only needs an energy storage device (batteries) if the owners want it to be completely off the grid. However most home owners choose to install a "net meter" (http://residentialsolar101.org/technology). A traditional meter only measure the power used and generally home owners are billed on a monthly basis. A net meter spins forwards when energy is used but spins backwards when energy is created by the solar panels and is fed back to the grid. Because a net meter and spin forwards and backwards a home own is only charged for the "net" amount of energy used. Often net meter users are only billed at the end of the year since they may generate more energy than they use in the summer, than use more than they generate in the winter, and via the net meter their usage will almost zero out.
It would not need a storage device unless the house was separate from the electricity grid. Many houses around the world generate electricity from solar panels and sell it to the power companies, sometimes the total amount, and sometimes only the excess.A person who uses solar energy in their isolated home would need some type of energy storage device to store the solar energy during the evening. They would also need to store energy for days when there is little or no sun.Because you need the stored energy when there is no sun to power the solar panels (rain/cloudy/night/winter).
That only applies if the home relies EXCLUSIVELY on solar energy, or to a large extent.The problem here is that you can't get solar energy at night, or when it is cloudy. Therefore you need to store at least some energy, for when you need it.
Because solar energy doesn't happen at night.
Because solar energy is only available when the sun shines. Not very practical with lamps that only shine when the sun is up.
solar energy can work in your home when you add solar panels to your roof.

Passive refers to a design that uses natural sunlight. It can be for lighting, as in skylights and large windows, or heating, where thermal glass is used. Active requires collecting solar energy with equipment ( pumps, storage tanks, etc. ) and storing or transferring the energy to where it is needed.
There are several online sources on information about home solar energy systems. You can also check at your local library for books on home solar energy systems

One of the cheapest form of solar energy for any home is to have a professional install a large solar panel that connects to the home. This will help reduce the energy costs in the home.

Generators do not store energy they produce energy. A storage device for DC voltage is a battery. AC voltage can not be stored.
