The concept of living fully off the grid is appealing to some solar power enthusiasts. Instead of disconnecting from the grid, it is more beneficial to invest in a battery backup system.

If your solar battery ever dies, you can still rely on the grid for backup power as long as you're connected to it. With net metering, you may even be paid by your utility provider for the power you produce but don't use.

In this post, we'll discuss what hybrid solar PV systems are, why they can be preferable to off-grid ones, and which solar batteries work best. Find out whether a hybrid system is the best renewable energy solution for your home's electrical demands by reading this.

What is a Hybrid Solar System?

Using the energy produced by solar panels requires a conversion process before it can be used to power your house. There are a few ways to achieve this: you may stay connected to the grid, go entirely off-grid, or have a hybrid system.

Solar hybrid systems keep your panels linked to the utility grid while also storing extra energy in batteries. Through an inverter, the solar energy collected by the panels is converted into useful power. The power is then either sent to your house, stored in a battery, or released back into the grid.

A hybrid solar system guarantees continuous electricity production regardless of external factors. If you have a backup battery, you can save the energy that your solar panels generate but that your house doesn't need. Afterward, this battery will provide your energy needs throughout the night, during system outages, or during severe weather when the sun isn't shining.

If the energy stored in your hybrid solar system's battery is completely depleted, you may still get electricity from the grid.

How a hybrid solar system works

In order for a hybrid solar system to provide electricity to your house, solar panels must first transfer their output to an inverter. Your house battery stores any excess energy that is generated but not needed to power your home.

When solar panels aren't providing enough electricity, this battery can keep your house running. If there is energy left over after those processes, it is fed into the grid.

How much does a hybrid system cost?

A 6 kilowatt photovoltaic (PV) solar system, which can provide enough energy to power most American houses, costs about $12,000 in the United States once the federal tax credit is applied (as of August 2022). The price of installing a solar energy system depends on many factors, including the size of your house, the cost of the contractor, and the price of solar panels in your state.

The cost of hybrid solar systems is inflated by their reliance on a backup battery. You should plan on spending at least $8,000 per decade to replace your batteries since they only have a decade or so before they die.

With a backup battery, you may rest certain that your house will always have electricity, but you must weigh this convenience against the expense.

In what ways do hybrid solar systems benefit from different types of batteries?

While solar lead acid batteries were formerly prohibitively expensive, they have become more affordable in recent years.

Solar batteries from Panasonic and Sunpower are widely regarded as the best on the market today.

  • Panasonic EverVolt: The AC-coupled home battery storage option has a storage capacity of 11.4 kWh to 17.1 kWh for off-hours usage. Up to a day's worth of power might be provided by this. Panasonic's battery also comes with a generous 10-year guarantee.
  • Sunpower Equinox: The Sunpower Equinox battery has a capacity of 13 kWh–26 kWh and a 10-year product guarantee.

Popular battery options include the Tesla Powerwall as well as those from Panasonic and Sunpower. The 14 kW storage capacity of the Tesla Powerwall is what sets it apart from its rivals. This is about equal to half of the typical daily power use of a residence in the United States.

Also, powerwalls may draw from the whole range of available energy without harming the battery. The lights in your home will always be on with a Tesla Powerwall since they are durable and reliable.

Working with a professional installer means getting advice on which battery is ideal for your setup.

Is it preferable to go off-grid entirely or to create a hybrid solar system instead?

In contrast to a hybrid solar system, which may get its electricity either from the battery or the grid, being entirely off-grid means you'll have to rely only on a backup battery to keep up your energy consumption.

If you like to be in total control of your electricity supply, an off-grid solar system may appeal to you. However, you'll need to exercise extreme caution in your energy management and consumption practices to ensure that your backup battery is never depleted.

If you use up all your stored battery power too quickly or if bad weather prevents your solar panels from collecting enough sunlight for many days, a hybrid solar energy system may help keep the lights on until the sun comes out again.

Your electricity might go out during a hurricane or snowfall if you don't have this backup.

Is there a DIY hybrid solar system kit?

Installing solar panels yourself is a possibility; however, a hybrid solar system does not come in a "do-it-yourself" package.

If you want to install solar panels, you'll have to get the necessary equipment and pay for it yourself. Thankfully, services like Grape Solar exist to simplify this process. In addition to your do-it-yourself solar panel installation, a solar battery must be set up for the system to function as a hybrid.

DIY solar panel installation may save you money in the short term, but in the long run, it's better to have a professional take care of the permissions, inspections, and sizing your system to your needs.

The risks of DIY solar installation, such as missing out on rebates and harming your roof, outweigh the benefits.

A few things are required for a do-it-yourself solar panel installation, including:

  • Solar panels: 14–36 panels, depending on energy needs and panel efficiency.
  • Racking and mounting: a variety of options exist, some better suited to your roof pitch than others.
  • A solar grid-tied inverter: This transforms DC power into AC electricity that may be used by both the home and the grid.
  • Electrical wiring: This connects the solar panels to the hybrid inverter, which then connects to the residence, battery storage, or net meter.
  • Solar battery bank: A solar battery bank stores extra power for your house and is what distinguishes a hybrid system from merely grid-tied systems.

Benefits of a hybrid solar system: is it worth it?

In order to exert maximum control over one's electrical system, a hybrid setup is ideal. With solar panels and a backup battery, you may be your own energy supplier while still having the security of being linked to the main electrical system.

Hybrid systems' long-term cost savings more than compensate for their greater outlay of capital. The solar battery will keep the majority of the extra energy produced by your system rather than sell it back to your utility. Even though the net metering credits won't show up on your energy bill, you're still receiving the same amount of power. You might save even more money with a hybrid system if your power company doesn't provide complete retail net metering.

The versatility of a hybrid system lies in its ability to protect you from both adverse weather and the dark. If you need more power than your backup battery can offer, you can always plug into the grid.

In order to guarantee that you never have an energy blackout, hybrid solar systems are your best bet.

Does a hybrid system make sense for you?

To guarantee that solar energy is always powering your house, a backup battery is an excellent investment if you can afford one.

You may produce your own power while still enjoying the benefits of a grid connection, namely increased stability. A grid-tied solar system is a good compromise if you can't afford a backup battery.

In any case, you may save a lot of money and secure your energy independence by installing solar panels.


To sum up, a hybrid solar system is a renewable energy system that uses solar panels and a backup generator to continuously provide power to the grid. It is possible to utilize solar power throughout the day and then switch to the generator if the sun doesn't shine brightly enough or if the electricity goes out. Powering homes and businesses with power generated by hybrid solar systems may be an economical and dependable choice. They help safeguard the environment and advance sustainability by decreasing dependency on nonrenewable energy sources.

Which is better, an off-grid or hybrid solar system?

There is no way for off-grid inverters to sync up with the power grid. Those are meant to function independently. You can't inject solar or battery-generated electricity into the utility grid using an off-grid converter. However, the hybrid inverter may send electricity back to the mains.

What are the advantages of a hybrid system?

Hybrid systems provide you more leeway to adapt to changing needs since you may choose the precise instruments for your system independently of the bus.

What is the disadvantage of hybrid solar PV systems?

The primary drawback of a simple hybrid inverter is that it cannot provide electricity to your home in the event of a blackout since it lacks a grid isolation mechanism. That's why, if you have a reliable power grid, a simple hybrid inverter is your best bet.
