Yes. A big part of the reason that solar batteries are increasing in popularity is that they allow many homeowners greater control over their home energy usage. As a result, they have the chance to save money and rely less on grid-supplied energy, which tends to come from less environmentally friendly sources.
How “Time of Use” rates influence energy costs:
Most homeowners use more energy in the morning before leaving for work, and then again in the evening after returning home. These peaks in demand put a strain on public utilities because they try to supply the right amount of electricity at all times. In order to deal with this, some utilities have introduced Time of Use (TOU) pricing in order to curb demand. If your utility is one of the many that has introduced a TOU rate structure, then you’ll most likely be paying more for energy during times when you need it most.
