How Solar Batteries Work: A Quick Guide
Having a solar panel system without installing a solar battery is like wasting your energy for nothing. Here’s why: your solar panel system generates electricity, which is used according to your consumption, and any excess energy is sent to the grid. However, solar panels only work when the sun is out. Since you will need electricity at night for your home appliances, a battery solar system plays a major role by storing excess energy during the day and providing backup power when needed.
During the day, solar cells collect electricity from the sun and convert it into DC power. Your inverter then converts this DC into AC power, allowing you to use your home appliances directly from the switchboard. Any excess energy is sent from the inverter to the battery, where it is stored for later use.
At night, when energy is required, the solar battery sends stored power to the inverter. The inverter converts DC into AC power for your home appliances, and the switchboard directs the electricity to where it’s needed. If the battery gets depleted, you can still purchase electricity from the grid to meet your nighttime energy needs.
Why Invest in Solar Batteries in Victoria?
- Reduce electricity costs by using less grid power.
- Becoming solar-independent is always a smart financial investment for the future. Rather than buying electricity from the grid, generating your own power with a solar battery system is a better and more convenient option. Without a solar battery, you can only cover about 30%-40% of your household’s energy consumption. However, by installing a battery solar system, you can achieve up to 100% energy self-sufficiency.
Enjoy Reliable Power Even During Blackouts Your home appliances need a constant flow of energy to run. A sudden power supply breakdown can be frustrating. The latest solar battery systems in Victoria are capable of providing you with an uninterrupted power supply during outages. Installing a battery ensures reliable power backup for your home’s energy requirements.
Reduce Your Environmental Impact with Clean Energy As people become more aware of reducing their carbon footprint and taking steps toward a sustainable future, Aussies have made significant progress. However, a large part of Australia still relies on high-emission energy sources. Installing a battery solar system can accelerate the process of reducing carbon footprints.
Join a Solar Battery VPP for Smarter Energy Management A Virtual Power Plant (VPP) connects your battery solar system to a network that helps balance the grid while offering financial benefits. These include household savings alongside solar panels and batteries.
Things to Keep in Mind When Picking a Solar Battery
Capacity & Power
The total amount of electricity a solar battery can store is generally measured in kilowatt-hours (kWh). However, without knowing the power rating, you cannot determine how well it will work with your home and solar system. The power rating, measured in kilowatts (kW), determines how much electricity the battery can deliver at a given time.
A low power rating with high capacity generates less electricity at once but can run some appliances for an extended time.
A high power rating with low capacity can power your entire home but only for a short duration.
Depth of Discharge (DOD)
DOD can be compared to fuel in a car—the less fuel you have, the shorter the distance you can travel. DOD represents the percentage of battery capacity that can be used without damaging its lifespan. A higher DOD means greater usable battery capacity.
Efficiency
Efficiency tells you how much energy you can use after charging and discharging the battery. It’s important to check the round-trip efficiency, which indicates the exact amount of stored power available after accounting for energy loss. The higher the efficiency, the lower the energy loss.
Battery Life and Warranty
Battery Life Battery life is measured in cycles (one full charge and one full discharge). It determines how many cycles a battery can go through before its capacity declines. When selecting a battery, choose one with a higher cycle count, as this translates to a longer lifespan.
Warranty
Warranties are provided by manufacturers and cover repairs or replacements within the warranty period. Before purchasing, always choose a solar battery system with a long warranty period. Lithium-ion batteries are more durable than other types, often offering warranties of 10 to 15 years.
