An on-grid solar system (also called a grid-tied solar system) is a solar power setup connected to the public electricity grid. It uses solar panels to generate electricity, which is either used on-site or sent back to the grid. When the solar panels produce more energy than needed, excess electricity is fed into the grid, often earning credits through net metering. When solar production is insufficient, electricity can be drawn from the grid. On-grid systems do not require batteries for storage, making them cost-effective and efficient, with the grid acting as a backup power source.
Solar Panels (Photovoltaic Panels):
Convert sunlight into electricity using photovoltaic cells.
Inverter:
Converts the DC (direct current) electricity produced by the solar panels into AC (alternating current) electricity, which is used in homes and businesses.
Electric Meter:
Measures the electricity consumed from the grid and the excess solar power exported to the grid.
With net metering, you can receive credits for the surplus energy generated.
Grid Connection:
The system is connected to the local electricity grid, allowing for bi-directional energy flow—solar power going to the grid and grid power coming to the system as needed.
Cost Savings on Electricity Bills:
Reduces reliance on grid electricity, lowering monthly electricity costs.
Excess power can be sold back to the grid (via net metering) and credited to your account, reducing overall energy costs.
No Battery Storage Needed:
Unlike off-grid systems, on-grid systems don’t require expensive battery storage. Excess energy is sent to the grid instead of being stored for later use.
Environmentally Friendly:
Solar energy is renewable and clean, helping to reduce your carbon footprint by decreasing reliance on fossil fuels and conventional power sources.
Grid Independence (During Daylight Hours):
During the day, when sunlight is abundant, your home or business may run entirely on solar power, reducing the amount of energy pulled from the grid.
Government Incentives and Rebates:
Many governments offer incentives, tax credits, and rebates for installing solar panels, making it more affordable in the short term.
Easy to Scale:
On-grid systems can be easily expanded if you want to increase energy production by adding more solar panels or upgrading the inverter.
Low Maintenance:
On-grid systems require minimal maintenance. Solar panels generally last for 25 years or more, and inverters may need replacing after 10-15 years.
Reliable Power Supply:
The grid acts as a backup, ensuring that you have access to power even if your solar panels aren’t producing enough energy, such as during cloudy days or at night.
Increase in Property Value:
Homes and businesses with solar power systems are often viewed as more energy-efficient, and may have higher resale values.
No Need for Large-Scale Battery Storage:
By feeding excess energy back to the grid, you eliminate the need for expensive energy storage systems, keeping overall costs lower.
