There are a few reasons why you may want to store solar energy with batteries. One of the most common reasons is to avoid high utility rates. Storage is a sort of insurance policy against bad weather. With this, you can use the energy stored in your battery when solar panels are not producing enough energy to meet your needs. Additionally, you can store more energy if you have a larger area than your home’s roof. But what exactly is the benefit of a storage system?
Batteries are great for backup power, but they are also costly. If you need to power key circuits all day, you can store a few hundred volts of energy in a single battery. The main disadvantages of lead-acid batteries are their short life and the need for regular maintenance. But if you’re serious about saving money, you’ll want to look into a solar battery system that can store surplus energy.
A lead-acid battery is the cheapest type of solar energy storage, but they tend to be heavy and require ventilation. Their DoD (Depth of Discharge) makes them an impractical backup system, but their price is still affordable. A downside to lead-acid batteries is their maintenance requirements. They can be difficult to maintain and should be disposed of properly.
