What type of battery bank would i need to store energy from a solar panel used to power a house, and what would be the cost?
a big one.
You need to answer a few questions:
1. What is your average power usage. You can get that from old electric bills. Typical is 1000 watts.
2. How many hours without sun do you want the batteries to continue to supply power when there is no sun. Obviously you need the nite hours, but how about 2-3 days when it is raining?
Lets try a sample calculation of 24 hours, and 1000 watts. That is 24000 watt hours. A large marine sealed lead acid battery can supply about 1000 watt hours, and costs about US$300. But in this case, you would need 24 of them, a lot of money and storage space and maintenance. Change to 2000 watts and 2 days and it quickly spirals out of control.
One alternative you should investigate is selling power to your power company when you have excess and buying when the sun isn’t shining. Some allow this, and it saves on the battery cost and maintenance.

You have to get solar panels to generate the load of your house hold equipments.Then the capacity of the battery
Again, the electrical equipments design voltage must match with the out put of battery or you have to install invertors and transformers to match the voltage and supply.
Battery must be chargeable type and tublar batteries are used now a days.
