What is a hybrid solar system? How does it work? A guide

Going solar doesn't just mean installing solar panels — hybrid solar systems include battery storage so you can save the power your panels generate during the day and use it later, when the sun isn't shining. Learn how Panasonic solar and battery storage systems can help make your home more energy independent.

A hybrid solar system integrates battery storage with solar panels and connects to the grid. During daylight hours, the solar panels generate electricity, and any surplus energy is stored in the batteries for nighttime use when the sun is not available.

Hybrid solar systems are known for their efficiency, reliability, and being a wise investment for homeowners wanting to harness solar power.

What is a hybrid solar system?

A hybrid solar system utilizes solar panels, a hybrid inverter, and a battery bank to generate and store electricity. Solar panels convert sunlight into electricity, while the battery bank stores the excess energy for later use.

These systems provide both on-grid and off-grid capabilities, ensuring power availability even during grid outages.

How does a hybrid solar system work?

Hybrid solar systems generate electricity using solar photovoltaic (PV) panels and manage energy use smartly by switching between solar power, battery storage, and grid power. This capability helps you avoid using expensive grid power during peak hours, reducing your electricity bills.

The system stores the renewable energy produced by the solar panels on your roof. In the event of a storm or power outage, the system automatically kicks in to power essential household loads, keeping critical devices like lights, refrigerators, and phones operational.

The benefits of a hybrid solar system

A hybrid solar system is ideal for those who prioritize uninterrupted power during outages, or those dealing with utility companies that use time-of-use rates and demand charges but do not offer net metering for excess energy sent back to the grid.

This type of system can effectively manage time-of-use electricity rates, further maximizing solar savings on your monthly electric bills.

1. Cost-Effectiveness

Hybrid solar systems enable you to lock in low energy rates for years, protecting you from future rate hikes. It also allows for efficient management of time-of-use rates for maximum savings.

2. Flexibility and Scalability

Hybrid systems are customizable to meet specific home energy needs and can be scaled for future energy requirements. For instance, if a homeowner needs a backup power source for essential loads like medical equipment, the battery bank can be sized accordingly to meet those needs. Hybrid PV systems thus offer flexibility and scalability unmatched by other PV system types.

3. Environmental Sustainability

As more people seek ways to reduce their carbon footprint, hybrid solar systems become an excellent option for those committed to environmental sustainability.

4. Reduce the Risk of Outages

Designed to provide power during grid outages, hybrid solar systems ensure you have electricity even when the grid is down due to technical issues or severe weather, maintaining your home's functionality.

Conclusion

In conclusion, hybrid solar systems are a fantastic choice for homeowners aiming to lower electricity bills while ensuring reliable power during outages. If you're interested in a hybrid solar system, be sure to research and find a reputable solar panel installer.

There are three types of solar panel systems: grid-tied (on-grid), off-grid, and hybrid solar systems. Each type has a distinct setup impacting equipment use, installation complexity, and the overall cost and savings potential.

Which one is the best for your needs? Let's delve into the pros and cons of each solar system type.

Grid-tied solar systems

Grid-tied systems connect solar panel installations directly to the utility power grid, allowing homes to use both solar energy and electricity from the grid. If the panels generate more electricity than needed, the excess is sent back to the grid, sometimes earning bill credits through net metering policies.

Grid-tied systems are popular due to their cost-effectiveness, especially in areas with full-retail net metering, but they don't provide power during outages.

Pros

• Cheapest home solar system

• Requires less equipment

Cons

• No backup power

Off-grid solar systems

Off-grid systems are completely disconnected from the utility grid. They require extensive battery storage and often an additional power source like a generator. These systems are common in remote areas lacking grid access.

Off-grid systems offer self-reliance and are critical for remote locations but tend to be very expensive due to the significant battery storage needed and require mindful energy consumption.

Pros

• Provides electricity where there is no grid access

• Self-reliant

Cons

• Very expensive

• Requires lifestyle changes

Hybrid solar systems

Hybrid solar systems, also known as "solar-plus-storage" systems, combine the attributes of both grid-tied and off-grid systems. They connect to both batteries and the grid, providing power during outages and reducing reliance on the grid through stored energy usage.

These systems can maximize clean energy use and save money, although the high upfront cost of batteries might not always make financial sense.

Pros

• Provide backup power

• Increase energy independence

• Can potentially save more money on electricity bills

Cons

• Expensive

• Not always the right financial choice

How to pick the best solar system for you

Generally, a simple grid-tied system offers the best financial return due to its low initial costs and straightforward design. However, a hybrid system might be more appropriate if you experience frequent outages, prioritize energy independence, or want to maximize the use of renewable energy for your home.

Off-grid systems, while less practical for most homeowners, are perfect for remote locations like mountain cabins. The best approach is to contact local solar companies who can provide personalized advice based on your specific needs and conditions.
