Yes, you can store excess energy generated by your solar panels using battery storage systems. Solar batteries, such as lithium-ion batteries, store surplus electricity during the day when your panels are producing more energy than you need. Then, you can use this stored energy during the night or when your panels are not generating electricity, further reducing your reliance on the grid and increasing your energy independence. Battery storage also provides backup power during outages, enhancing your energy resilience. The use of solar batteries can optimize your energy savings and help you achieve a higher level of self-sufficiency.
