Development of solar home system with dual energy storage
It is seen that the dual energy storage would reduce the energy storage cost by 72–87% if using Li battery only and 41–52% if using LA battery only except D5. D5 utilizes a rather large heat storage (about 78% of total energy storage capacity), and this causes no cost reduction even using all LA battery to replace it. That is, using LA battery only to replace Li …
