According to the International Energy Agency’s World Energy Outlook 2020, solar energy has become the “cheapest electricity in history.” Its affordability, environmental benefits, and accessibility make it an appealing option for homeowners considering a switch to one of the most efficient renewable energy sources. Before making this transition, it’s essential to understand the different types of solar power systems available.
The two most common solar energy solutions are:
- Hybrid Solar Energy Systems
- Grid-Tied Solar Energy Systems
Both systems utilize solar PV panels to generate electricity, which is converted into a usable form with the help of an inverter. The generated solar energy can be self-consumed, stored, or sold back to the grid depending on the system in use.
1. Hybrid Solar Energy Systems
A hybrid solar energy system operates similarly to a grid-tied system in terms of energy generation but provides the added advantage of grid independence. These systems can operate continuously, regardless of grid availability. They include energy storage that allows excess energy to be stored for later use, such as during nighttime or power outages. This capability makes hybrid systems resilient during blackouts and allows for energy usage during high tariff hours, leading to lower electricity bills. Any surplus energy that isn’t self-consumed or stored can be exported back to the grid, potentially yielding greater savings and a quicker return on investment.
Key benefits of hybrid solar energy systems include:
- Energy Storage: Excess solar energy can be stored for later use, ensuring consistent power availability.
- Outage Resilience: They remain functional during power outages or load shedding.
- Cost Savings: Stored energy can be utilized during peak tariff hours, reducing reliance on grid electricity.
- Net Metering: Surplus power can be sold back to the grid, benefiting from zero or negative energy bills.
- Reduced Policy Dependency: They are less affected by changes in net metering regulations compared to grid-tied systems.
- Scalability: Additional storage can be added without needing to replace the existing inverter.
While hybrid systems have a higher initial cost due to the hybrid inverter and batteries, they tend to be more reliable and can often recoup the initial investment faster than grid-tied systems.
2. Grid-Tied Solar Energy Solutions
Grid-tied solar energy systems connect directly to the electrical grid and are unable to generate power when the grid is down. They only produce solar energy when both the sun is shining and the grid is operational, making them less effective during power outages or load shedding. These systems lack energy storage capabilities, meaning that excess energy cannot be saved for future use. However, grid-tied systems do offer net metering, allowing excess electricity to be sold back to the grid.
Although grid-tied solar energy systems are generally more affordable, their inability to store energy and reliance on the grid for power savings make them highly dependent on external sources for continuous electricity generation.
