Solar energy has become an attractive option in the search for sustainable energy sources. Choosing the correct solar system with a battery is crucial because more and more people and companies are using solar panels to gather solar energy. An essential function of solar batteries is to store extra energy produced in sunny spells for use on overcast days or at night. We’ll go over the important aspects to consider when selecting the best solar system with a battery for your needs.
What Is A Solar System With A Battery?
The solar panel captures light from the sun and converts it into electricity for home
appliances. The electricity is used directly, but if you connect a battery, you can store the energy for future use.
When batteries and solar panels are integrated, further electricity generated by your
solar panels during the day is not lost.
Alternatively, when your panels aren’t receiving enough sunshine, you can store them and
use them at night or on overcast days. Solar battery storage is one of the effective ways to energy saving.
This configuration is very useful since it reduces your reliance on purchasing
electricity from businesses, which can result in cost savings and environmental benefits as it uses less energy from
fossil fuels.
How Does Solar Battery Work?
Solar battery works as solar battery backup. Solar panels, consisting of solar cells,
convert sunlight into electricity through the photovoltaic effect. The electricity is converted into AC using an
inverter. A battery stores excess electricity, similar to a rechargeable battery. When Sunpower panels aren’t working, the battery can
provide stored energy to power the home. Modern solar batteries often have smart technology that optimizes energy
storage and usage, saving costs and making the most of sunlight.
Why Combine Solar With Solar Battery Storage?
Why Combine Solar With Solar Battery Storage?
- Storing Extra Energy For Later Usage:
Utilise stored energy at night or during blackouts to achieve energy
independence.
- Lower Energy Costs
Utilise stored energy instead of obtaining electricity from the grid to maximize
self-consumption.
- Enhanced Savings From A Decrease In The Solar Feed-In Tariff
Energy storage becomes more economical than selling excess power back to the
grid as feed-in tariffs decrease.
Main Components Of Solar System With Battery Storage
A solar and battery package is an effective combo to store renewable energy. Some of the
main components are:
- Solar Panels
With photovoltaic (PV) panels, sunlight is converted to electrical power. Seek
out high-efficiency brands like SunPower, REC, or LG.
- Inverter
converts the DC output of solar panels into AC power for home use. Hybrid
inverters regulate both solar input and battery storage.
- Storage Battery
Lithium-ion batteries, like those found in LG Chem and Tesla Powerwall, are
well-liked due to their durability and effectiveness. Also requires a solar battery charger.
- Observation System
Use apps to monitor energy production and use to maximize savings.
How To Calculate The Size Of Solar And Battery System
- Get To Know Energy Consumption
Check your electricity bill to find out how many kilowatt-hours (kWh) you
consume each day. In Australia, the average household uses 16–30 kWh daily.
- Calculate Solar Panel Requirement
A typical 1kW solar panel installation generates about four kWh per day under
optimum conditions. It would take a 5–6 kW solar system to cover 20 kWh of electricity each day.
- Determine Battery Size
The amount of energy you wish to store determines a battery’s size.
Types Of Batteries For Solar System
Lithium-Ion Batteries
Because of their lightweight, small size, and extended cycle life, advanced
lithium-ion batteries—which are renowned for having a higher energy density, a longer lifespan, and fewer
maintenance needs—are becoming more and more popular.
- Lead-Acid Batteries
Conventional, less expensive batteries in solar power systems are more
susceptible to temperature changes, have a shorter lifespan, and need routine maintenance. They are
nevertheless commonly utilized despite these disadvantages.
- Saltwater Batteries
Compared to lead-acid and lithium-ion batteries, saltwater-based batteries have
a lower energy density, a longer lifespan, and a higher temperature tolerance. However, they are less widely
utilized and do not contain any hazardous ingredients.
- Flow Batteries
Flow batteries are a sort of energy storage technology that has scalability,
durability, and a long lifespan. They are made up of two electrolyte tanks that flow through a membrane to
generate electricity through a chemical reaction.
Advantage Of Solar Panels With Battery
● Increased Energy Independence
● Cost Saving
● Rate Optimization
● Provide Backup During Outages
● Decrease Of The Carbon Imprint
Disadvantages Of Solar Panels With Battery
● Initially High Cost
● Battery Maintenance And Longevity
● Installation Could Need A Substantial Amount Of Roof Space
Solar System With Battery Cost In Australia
The cost of the solar system with battery storage depends on various factors such as
system size, battery capacity, and installation requirements.
- Solar System Cost
The initial cost of a 5-10kWh solar system is between $5000 – $10000, depending on the quality of the panel and inverter used.
- Battery Cost
Battery cost depends on the battery capacity. 5kWh battery cost is $5000 – $7000, whereas 10kWh battery cost is $6000 to $15000.
- Installation Cost
The installation cost depends on the complexity of the system. The cost is typically $1500 to $3000.
Conclusion
Investing in a solar system with battery storage guarantees long-term cost savings, environmental benefits, and energy independence. Whether you choose an off-grid or hybrid setup, make sure your system is properly sized, has high-quality parts, and utilizes any government incentives that may be available. With the right installer and the right preparation, you may enjoy consistent, clean energy for many years to come. GOAL Solar is one of the best Solar suppliers australia.
