Basking in the abundant sunshine, solar panels offer a transformative way to shape Australia’s energy landscape.
With an average of 250 sunny days, the data shows over 3 million Australian houses are now equipped with solar energy systems. They are embracing this renewable energy source to reduce their carbon footprints and adopt more sustainable lifestyles.
But as the solar adoption rate rises, a trending question emerges: Are solar panels connected to electricity?
The question might have multiple answers depending on your location, purpose for using solar, and environmental conditions.
So, in this blog, let’s explore the question further and find all the possibilities of integrating solar panels with electricity!
Solar Energy 101: Power Your Home with Sunlight
Solar energy systems are renewable energy sources derived from direct sunlight. They offer a sustainable energy solution that is replenished faster than utilized.
Moreover, solar plays a pivotal role in mitigating climate issues by lowering carbon emissions and reducing the reliance on fossil fuels. From heating and cooking to powering homes and vehicles, this energy is widely used for various applications.
So, before delving into the complicated part, let’s examine the basics of solar panels and how they work with electricity.
What Are Solar Panels?
Solar panels are devices that trap sunlight with their PV cell surface and convert light into usable electricity. The cells are usually made from silicon wafers, and they can power electrical loads during cloudy days or nighttime.
Solar panels can be classified into three leading groups: Monocrystalline, Polycrystalline, and Thin-film panels.
Each of them has unique features that work well in different scenarios. For example, Monocrystalline solar panels are best suited for residential use. They are more compact, durable, and highly efficient.
On the other hand, polycrystalline or thin-film solar panels are a good fit for large-scale projects and industrial setups. They are bulky, have lower heat tolerance, and last shorter than Monocrystalline panels.
Some of Australia’s most efficient Solar Panels, like SunPower, REC, Jinko, and Trina, also use Monocrystalline panels.
Despite their high prices, Monocrystalline panels’ high-efficiency rates (15-20%) and longevity of around 25 years made them a popular option in the solar panel industry.
How Do Solar Panels Transform Sunlight?
From the above part, you already have an idea about solar panels. But do you know how solar panels work?
Well, the process is pretty simple:
The solar panel turns sunlight into electricity through the photovoltaic effect. In this process, as the sun’s rays hit the solar panel’s surface, they start to excite the electrons in silicon.
The electric field inside the solar cells pushes these free electrons, resulting in an electric current flow known as direct current (DC).
Now let’s see how solar panels work with electricity.
Since most Australian households are grid-tied and use alternating current for home appliances, DC electricity must be converted before use. An inverter assists in this DC-to-AC conversion, and the converted electricity is then distributed and used to power homes.
However, by adding solar battery storage, excess energy can be stored for later use instead of being sent back into the electricity grid.
Are Solar Panels Always Connected to Electricity
The answer is “No.” Solar panels don’t always require an electricity connection to generate power. Even without an external electric connection, they can produce electricity using sunlight.
Wondering when solar panels require an electricity connection? This actually depends on the system design and how the electricity is used.
As mentioned earlier, solar panels produce electricity in the DC form that the inverter needs to convert to AC electricity. These solar inverters come in various forms, and some require an external power source to perform their task.
Let’s hover over the following segment for a clear understanding. Shall we?
Bridging the Gap | How Solar Panels Connecting Electricity Grid in Australia
Even though solar panels can be a clean, reliable power source, they won’t always be able to fulfill all your energy needs. Why?
Solar energy is intermittent! This means that solar power generation fluctuates based on several factors, such as daylight hours, weather conditions, and seasonal variations.
The sun’s angle and irradiance change with the season and time of day, thus impacting the overall energy production rate. Therefore, it’s better to connect the solar panel to electricity to manage the intermittency and overcome the energy issue.
By integrating solar power with other renewable sources, energy storage systems, or electric grids, you can enjoy a more reliable, consistent, and resilient energy system.
So, keep in mind that solar can minimize but not entirely eliminate the power that can be obtained from the electric grid system.
Exploring Types of Solar Panel Connections
In general, three types of solar inverters are available in the market: On-Grid, Off-Grid, and Hybrid Inverters.
Among all the types, only On-grid solar inverters need an external electricity connection to convert DC power into AC power. While, Off-grid and Hybrid inverters can function independently without an electric connection and use battery storage as a backup.
Grid-Tied Solar Systems
On-grid or grid-tied solar systems use string inverters that are directly connected to the utility grid. In Australia, most houses with rooftop solar are tied to the national grid system, which is less complex and more cost-effective.
The inverters help in the DC to AC-conversion process. This synchronization with grid power allows excess energy to be fed back into the grid, ultimately saving electric costs.
However, it’s important to remember that on-grid systems do not provide power backup during grid outages. You must have your own backup system, like generators or batteries, to power your home.
Off-Grid Systems
Residents don’t need to connect solar panels to electricity in an off-grid solar solution. As it is disconnected from the grid, this stand-alone power system operates best in remote locations where grid access is unavailable.
Also, the off-grid system needs battery storage to store this excess power during peak daylight hours. As solar energy is only available for 6 to 7 hours during the day, this excess energy can be used for nighttime.
So, how big a battery should you opt for?
Well, it depends on the resident’s energy usage pattern. Some houses can run with a 6KW battery, while others need a 10kW battery to run smoothly for longer hours.
Hybrid Systems
Are you looking for a flexible energy system? Hybrid systems allow you to benefit fully from both on-grid and off-grid functionalities.
In this system, users can store excess energy in batteries and also remain connected to the electric grid. Depending on the setup, they can either draw power from the grid or use stored energy from the battery, whatever they feel is suitable.
However, one issue is that hybrid systems are complex and usually more expensive than standard on-grid or off-grid inverters.
The Connection Process for Solar Panels with Australia’s Electrical Grid Systems
In Australia, solar panels connected to electricity are a game changer for an energy-efficient, sustainable future. But if you choose to install solar panels and connect with the Australian grid system, you must go through several steps.
Here is a detailed breakdown of how to connect solar panels to electricity or grid systems in Australia:
- In the initial phase of the grid connection process, homeowners must pick a reputable, expert installer.
- After the solar panel installation, they must send a grid connection application to the local electricity distributor.
- The application must have all the necessary details about the project, such as the size of the solar panel, expected energy generation, and solar installation plans.
- Then, after a certain application period, the electricity distributor conducts a technical assessment that includes evaluating local infrastructure and grid capacity.
The main purpose of this analysis is to determine the feasibility of connecting the solar panel technology with the grid system.
- The next step is negotiating and signing an interconnection agreement outlining responsibilities, costs, and timelines. Focus on how costs are shared between the utility and the project developer.
- After completing all the paperwork, the installer sets up a smart meter to track your electricity consumption rate and the energy your solar panel generates, which is fed back to the grid.
- Once everything is confirmed, the utility company will provide the final approval, and the system will be energized, allowing a connection to the grid.
- Maintain compliance with utility regulations and perform regular maintenance to ensure ongoing safe and efficient operation.
Overall, the grid connection process can be complex, often requiring collaboration among multiple stakeholders. Therefore, proper knowledge of local regulations and requirements is necessary to facilitate a smooth connection.
