Hybrid Solar Panel

According to data collated in 2021, solar power is used to generate roughly 10 percent of the world’s energy.^[1] While this might appear to be a rather paltry number, it is important to remember that photovoltaics are one of the most reliable sources of energy and their presence is indeed on the rise. This is also why a number of innovations have come to light in recent years. One example can be seen in a type of technology known as a hybrid solar panel.

What exactly is a hybrid solar panel? How does a hybrid solar panel differ from other common configurations? What advantages can hybrid solar panels offer and might there be any drawbacks to address? These and similar questions will be examined throughout the remainder of our article.

What is a Hybrid Solar Panel?

One common problem that has been associated with traditional photovoltaics involves the simple fact that the sun is not always shining. In other words, this technology serves little purpose on cloudy days or during the overnight hours. Such concerns are now being addressed with the use of hybrid solar panels.

The main intention of a hybrid solar panel is to store excess energy so that it can be used at a later time. This is accomplished through the use of an on-board battery. Briefly, a hybrid solar panel can be broken down into a handful of key components^[2]:

The solar panels themselves

A battery bank

First, the photovoltaic panels will capture the energy emitted by the sun. This is then sent to a hybrid inverter; a device that "intelligently" handles power output before sending this energy to the battery bank for storage.^[3] Note that an inverter will also change the type of energy from direct current (DC) into alternating current (AC). This is needed to power common items throughout a home or business.

A final interesting aspect of a hybrid solar panel involves the fact that it can also control the input from mains electricity sources. While hybrid solar panels are often considered off grid power systems, they can still be used in synergy with typical third-party networks.

The Types of Hybrid Solar Panels

Hybrid solar panels can generally be segmented into three discrete categories as seen below^[4]:

“Zero” generation
First generation
Second generation

Zero or "0" generation hybrid solar panels are the most basic models. These are comprised of a series of photovoltaic cells, a heat absorption unit and an electrical junction box.

First-generation hybrid solar panels are outfitted with an additional back insulating panel. This helps to prevent them from losing heat to the environment while providing the unit with a more energy-efficient edge. First-generation hybrid solar panels are currently the most common types utilised by consumers.

Second-generation hybrid solar panels are outfitted with an additional transparent front cover. This further reduces thermal loss and generally makes them more suited for colder environments. However, hybrid panels also cost more than the other two setups previously mentioned.

Is There a Difference Between Off Grid and Hybrid Solar Systems?

Readers may actually be surprised to learn that there are few functional differences between a series of solar panels reliant upon mains electricity and off-grid configurations. The main disparity is that hybrid panels will not need a third-party source of energy to function.^[5] This allows them to function at various other times in a similar manner to any other uninterruptible power supply (UPS).

The Benefits of a Hybrid Solar System

Now that we have a fundamental understanding of a typical hybrid solar panel, it is a good idea to peruse some of its advantages. Many will argue that the most notable benefit involves the ability of consumers to access a readily available power supply even if the panels themselves are not producing photovoltaic energy. This is once again due to the presence of an onboard battery bank. Here are some other unique attributes to mention^[6]:

This technology can be used in conjunction with other forms of alternative energy (such as a wind solar hybrid system).
Increased levels of reliability due to battery backup.
Surplus energy can be exported back to the grid; resulting in further end-user savings.
Additional batteries can be installed without needing to upgrade the inverter.
They are ideally suited for locations associated with rolling brown-outs or otherwise unreliable grids.

These are some of the reasons why hybrid solar panels are also employed to address industrial concerns such as traffic technologies and systems that require around-the clock functionality.

Are There any Possible Drawbacks to a Hybrid Solar Panel?

There are still some possible hybrid solar panel pitfalls to mention. For example, hybrid solar panels are considerably more expensive than traditional versions. Furthermore, users will need to be trained in the proper maintenance techniques. Hybrid panels also have a shorter lifespan in relation to standard models; generally between seven and 14 years. Replacements may thereafter be warranted.^[6]

Conclusion

Whether employed within the measurement technology sector or used for domestic purposes, hybrid solar panels are here to stay. When used in conjunction with cutting-edge fuel storage systems, the benefits become even more clear. There is little doubt that hybrid solar panels should enjoy a bright and efficient future.
