Hybrid solar systems allow homeowners to use both solar and grid energy. These systems offer the self-sufficiency of off-grid solar setups while still connecting to the main electricity grid. During peak sunlight hours, solar panels generate energy and recharge battery storage. If there’s a solar shortage, like during cloudy days or at night, the grid power comes into play.
The upfront costs of a hybrid solar system can vary based on system size and design. Our team reviewed the best solar companies available nationwide that offer hybrid solar systems. Below, we’ll explore how hybrid solar systems work, how much they cost, and the pros and cons of using them.

How Does a Hybrid Solar System Work?
A hybrid solar system combines the function of photovoltaic panels with energy storage techniques. Solar panels on your roof or on the ground convert sunlight into electricity that powers your home. Any excess energy flows into the grid or a battery bank, where it is stored for later use.
Other key components of a hybrid solar system include the following:
- Battery bank: Solar batteries (typically lead acid or lithium-ion batteries) store energy that isn’t used immediately.
- Charge controller: The charge controller protects batteries from overcharging, which limits their lifespans.
- Hybrid inverter: The hybrid inverter converts the direct current from solar cells into an alternating current. It also manages the power from the solar panels and the battery and connects to the grid.
- Metering/monitoring system: Hybrid installations include a solar metering and monitoring system that tracks energy production and usage. This system also monitors efficiency and helps with energy management.
- Solar panels: Each panel, or module, is made up of dozens of solar cells that capture sunlight and generate electricity.
Hybrid systems combine on-grid and off-grid capabilities. They ensure a continuous power supply by switching between solar power, battery power, and grid power as needed. This means you’ll have power even during grid outages or cloudy conditions.
Hybrid systems minimize reliance on the grid, allowing you to use stored power during peak price times or emergencies.
Hybrid Systems vs. Grid-Tied Systems vs. Off-Grid Systems
Homeowners can choose from three main types of solar power systems:
- Grid-tied solar system: Grid-tied systems include a solar inverter that connects directly to the utility grid, which directs surplus energy back to the grid.
- Hybrid solar system: Hybrid systems connect to the grid and a battery system. These systems can draw and convert energy from solar panels or storage.
- Off-grid solar system: Off-grid systems are self-sufficient and send surplus energy to storage batteries.
Benefits of a Hybrid Solar System
A hybrid solar panel system can help you save money on your electricity bills or provide your home with a battery backup. Hybrid solar systems offer a range of benefits for homeowners, including the following:
- Cost savings: Homeowners can save money on their monthly energy costs by using hybrid solar systems. The combination of solar power and battery storage is especially advantageous if a local utility company doesn’t offer net metering or charges time-of-use rates. You can increase your savings if you implement solar heating systems throughout your home.
- Flexibility: You can customize hybrid systems to meet your unique energy needs as they change.
- Peace of mind: A hybrid system functions as a home battery during power outages or blackouts so you can continue to use essential appliances.
- Sustainability: A hybrid solar system produces clean, renewable energy, reduces your reliance on fossil fuels, and ensures that any surplus energy doesn’t go to waste.
Homeowners can often qualify for state and federal tax credits, such as the federal solar tax credit, if they invest in hybrid systems. Some solar panel manufacturers and utility providers offer rebates and incentives for consumers who invest in solar energy systems.
Hybrid Solar System Disadvantages
There are some disadvantages to using hybrid solar systems, including the following:
- Compatibility concerns: There is no guarantee that current hybrid converters will be compatible with newer, more efficient battery designs, which could restrict your future upgrade options. Upgrading an existing solar system to a hybrid setup is costlier and more complicated than you might expect.
- Complex installation: Installation of a hybrid setup is complex, which can translate to higher up-front costs.
- High up-front cost: The initial cost of a hybrid system can be prohibitive. Hybrid inverters are typically more expensive than traditional inverters because they have more functions, and solar batteries can add thousands of dollars to the cost of installation.
Consider why you want to invest in solar panels to determine whether a hybrid system is worth the cost. The benefits of battery storage may not offset the higher up-front cost of a hybrid system. Grid-tied systems may be a better solution because they offer a simpler and more cost-effective option with a quicker return on investment.
Cost Considerations
A typical hybrid solar system setup costs homeowners an average of $30,000 for a 6kW system with monocrystalline panels and three lithium-ion batteries. Your costs could be significantly lower or higher depending on the size of your system and the quality of the components.
The types of panels and batteries your solar PV system uses are the most significant cost variables. Flooded lead-acid batteries and monocrystalline or thin-film panels are less expensive, while lithium batteries and monocrystalline or bifacial panels are more expensive.
Pricing varies by location, installation complexity, and the contractor you hire. DIY installation is not recommended, but you can save money by shopping around and comparing quotes.

Maintenance Tips for Hybrid Solar Systems
Regular solar panel maintenance ensures that your hybrid system continues to operate efficiently. These small steps can help optimize system performance and extend battery life. Here are some recommended practices:
- Check battery levels regularly to ensure adequate energy storage.
- Avoid overcharging and deep discharging the batteries, as these can damage battery life.
- Consider adding a battery monitoring system to track the state of the charge.
- Clean the panels every six months, and check battery health and the inverter every three to five years.
Our Conclusion
Hybrid solar systems cost more to install initially. These setups, which blend solar panels with batteries and sometimes a grid connection, provide off-grid power for nighttime usage and backup power during an outage. All-in-one solar systems offer reliable electricity, and their energy savings can help lessen costly electricity bills and utility price hikes. However, homeowners must weigh their energy needs and the solar panel system’s cost before investing.
A hybrid system’s estimated monthly energy savings vary by location, solar panel size, and other factors. Hybrid systems tend to make the most sense for customers in the Northeast or for those who use just over the average amount of electricity. We recommend contacting solar companies for an estimate specific to your home and budget.
FAQs About Ground-Mounted Solar Panels
How long does a hybrid solar system last?
The average lifespan of solar panels is up to 30 years, while inverters and lithium solar batteries need to be replaced after about a decade. Ten-year warranties are common for inverters and lithium solar batteries.
Are hybrid solar systems worth it?
Whether hybrid solar systems are worth it depends on your individual energy needs, local energy policies, and initial costs. Hybrid solar systems can be a good investment for those seeking energy independence and lower electric bills. They provide the benefits of both grid-tied and off-grid systems but have a higher up-front cost. We recommend talking to a solar company to discuss their perks and financing options.
Are there DIY options for hybrid solar systems?
You can find some DIY options for installing hybrid solar systems, but we recommend hiring a professional. Hybrid systems are complex. Professional installation ensures you’ll stay safe and remain in compliance with local codes and regulations.
What is the best battery for a hybrid solar system?
The best battery for a hybrid solar system depends on your needs and budget. Lithium-ion batteries are the most popular option because of their performance and lifespan, but they are more expensive than standard lead-acid batteries.
