Solar batteries are the unsung heroes of the renewable energy revolution. They seem like the power banks of the solar world, storing up all that sweet, sweet sun energy for when we need it most. So let’s look at what they are and what they do for us.
There are three main types of solar batteries: lead-acid, lithium-ion, and flow. But fear not, lead-acid batteries are relatively safe (just don’t try to drink the electrolyte, okay?). They’ve been around for over a century, so they’re kind of like the great-granddaddy of solar batteries. They’re reliable and affordable but have a shorter lifespan and lower energy density than the other types. Kind of like that old clunker car, you keep around for sentimental reasons.
Plus, using stored solar energy during peak demand times can help you save on your electricity bills, which means more money for, I don’t know, avocado toast or whatever the kids are into these days.
Depth of Discharge
Depth of discharge (DoD) refers to the percentage of a battery’s capacity that can be used before recharging. Higher DoD values mean more usable energy and a longer-lasting battery.
Round-Trip Efficiency
Round-trip efficiency is the ratio of energy used to the energy it took to store it. Higher round-trip efficiency means less energy is lost during the charging and discharging process, leading to greater overall efficiency.
