When is the best choice for lithium-ion solar cells?
Lithium-ion solar cells are the best solar energy storage systems for everyday residential use because they take up very little space while still storing a lot of energy. Plus, their high DoD means you can use more of your stored energy.
Batteries last longer, so they don't need to be replaced as often as lead-acid batteries. Plus, their higher efficiency means you can use more of the energy your solar panels generate and store - giving you good value for your money.
However, in some cases, other battery types, such as lead-acid batteries, may be more suitable for you. This is especially true if you're just using solar cells for backup power storage. Since you don't regularly drain your backup battery, the lower DoD and lifespan aren't as important, so there's no need to spend extra money for these features.
Lead-acid batteries are also popular in off-grid solar system projects that are not often used -- like vacation cabins. But for everyday use, spending more on lithium-ion solar cells may be your best bet.
Whether for off-grid battery backup or grid-connected solar systems, energy storage can help you run completely on clean energy. Contact your local solar installer to find the best solar system to pair with your solar panels.
