Solar Panel and Battery System Estimator
Use this estimator to get an idea of how many solar panels you will need to replace all of your current power consumption. It will also calculate how many storage batteries you will need to store that power.
Note: You DO NOT NEED TO HAVE BATTERIES in your solar system in order to make it work. You can purchase a grid-tied system which will complement your grid power with solar power. It allows the consumer to draw power from the grid when their system is not generating enough electricity to power your home, like at night or a cloudy day, thereby eliminating the need for batteries. This also allows individuals with surplus power (wind, solar, etc) to sell the power back to the utility. This is sometimes called "spinning the meter backwards" as that is what literally happens.
