A web tool that can be used to determine the size of a battery needed to store solar energy for a residential application.
During the day solar cells are producing more energy than ever before, but peak demand for electricity is in the evening time when solar cells are not producing. In order to meet peak demand, utility companies resort to producing energy from traditional sources. To combat this, a battery sizing tool will be build so that residential solar installations can college energy during the day for use at night to offset the need for utility companies to need produce. This problem is commonly referred to as the duck curve: https://en.wikipedia.org/wiki/Duck_curve
