A topic about the possibility of adding electrical energy storage to a home solar power system is receiving increasing attention. Today the general consensus seems to be still a bit dicey because payback times at current prices can be a decade or longer compared with significant operational and cost advantages offered by utilities, despite the solar-only or solar plus storage routes bring benefits of lower monthly electricity costs, protection against power outages, environmentally friendly, and partially or fully leaving the grid.
However, these calculations may look quite different in future years as traditional power costs increase, costs of PV and storage systems decrease, necessity of protecting the environment by reducing demand for fossil fuel generated electricity, financing options become more readily available and attractive, and people have more experience with solar and storage. This trend toward solar is already happening and is inevitable, as is global movement toward an energy system based largely on renewable energy.
