Imagine a small device installed on your balcony that can constantly generate electricity for appliances at home and even sell part of the generated electricity. That's something straight out of a science fiction movie, but it's real. The recent explosion of "balcony photovoltaic" is setting off a home energy revolution, and some people even boldly predicted that this might open the next "trillion-dollar market"! It means that we all have an opportunity to become a small power station "boss".

Definition of Balcony Photovoltaic

Balcony photovoltaic system, as the name suggests, is a compact photovoltaic power generation facility specially designed for the family balcony and other spaces. A new-type product, similar to an external unit of the air conditioner but installed on a balcony and connected via the power outlet, can easily become your mini home power station. Typically, a balcony solar system is comprised of panels fixed to balcony railings or walls and a unit for storing the energy of batteries. In summary, the system captures sun-generated energy during the day that it stores in batteries, drawing energy when demand is high during peak hours or at night. This type of PV is very suitable for townsmen, especially in big cities where most homeowners do not have a yard but live in apartments.

Why balcony PV has grown so popular

1. Plug-and-play advantage

Because of the plug-and-play installation, the balcony photovoltaic systems gain much favor. Compared with traditional house solar panels, these systems are rather easy to install and don't require any complicated building process. Users easily mount a PV system on the balcony using a miniature inverter mount for the balcony and quickly connect with an electrical outlet for fast building of a small facility for home power generation.

2. Simplified Grid Connection Process

This ease of installation, further sweetened by an easy grid connection process, has made the systems quite applicable for home self-generation. They work well with the existing power system whereby one can generate their own clean energy and decrease dependence on traditional sources.

3. Wide applicability

The applications of the balcony PV systems are many. Be it an apartment in an urban high-rise or a stand-alone home in the suburbs, these systems can be adapted to fit  balconies of different sizes, providing a flexible energy solution for all types of homes. This flexibility also extends the possibility of new ground being broken by the balcony PV systems in the renewable energy market.

4. A new focus on renewable energy

It is because of this simplicity and ease of use that the new focus of the renewable energy sector has been on balcony PV systems. This has also grown interest and demand rapidly, with rising interest in reducing carbon emissions and lowering energy bills. This is likely to push the expansion of the market in the balcony PV segment into the trillions and create huge opportunities for companies and investors.

5. Environmental benefits

This makes their positive impact on the environment not go unnoticed. These turn solar energy into electrical, contributing to a reduction of gas emissions and easing the environmental pressure of energy production. In a world that focuses increasingly on sustainability and the protection of the environment, balcony PV systems play a role in advancing the transition toward cleaner and greener energy use.

What is the economic advantage that balcony power plants provide?

It is difficult to generalize the economic value of a balcony power plant, since it is very dependent on several factors, such as the general size of a balcony may be small for placing and installing a specific number of photovoltaic panels according to the sunny direction the place gets or receives with the intensity of solar radiation in the same area that can be accepted by that panel.

Generally speaking, in the case of installation of a balcony power station on an area ranging from 1 to 2 square meters and located in a place with good conditions of solar radiation, it is possible to produce between 200 and 400 kWh of electricity per year on average for each photovoltaic panel.

It has to be underlined that these figures can be significantly different depending on the several conditions mentioned above. According to experts, home-installed balcony power plants can meet about 10 to 20 percent of a household's electricity needs. That is, even though a balcony power plant cannot meet all the electrical needs of a household, it can reduce dependence on the conventional grid to an extent and provide economic benefits to the household.
