4. Market Demand As consumer interest in sustainable energy grows, the demand for efficient solar panels increases. This heightened demand can lead to fluctuations in pricing, especially in competitive markets.
Since solar batteries store the excess energy generated by your solar panels, they are essential to your solar panel system. However, they can be costly depending on the type and size of the battery. For instance, a single lead-acid battery can cost between $200 and $800, while a residential lithium-ion solar system can cost $7,000 to $14,000.
