If you've ever been curious about balcony solar panel, then this article is definitely a must-read for you. Balcony PV has become a hot trend. Let's talk about this exciting new energy topic together.
1. What is balcony photovoltaic
Balcony photovoltaics, also known as micropower generation systems, are a compact solar power generation solution. It is no longer limited to large roof installations, but integrates high efficiency solar panels into balconies or building facades, enabling personalized energy production.
2. How balcony solar panels work
Balcony solar panel typically consist of one or two PV modules, typically with an output of 300 to 600 watts, with a solar microinverter attached to the back. It converts the generated direct current into alternating current for use by household appliances.
The cable can be connected to the power cord and then plugged into a normal socket on the balcony or in the apartment. This will connect the solar system to the home grid.
Once the light hits the solar module, electricity is generated, which flows into the home grid and powers the equipment that is currently needed. As a result, the meter runs slower and less electricity is drawn from the grid, saving money on electricity bills.
If the sun is shining, even if the family's refrigerator, router, and computer are all draining power, the meter counter can even stop completely. If the system generates more electricity than the home currently needs, the excess electricity can also be fed into the public grid.
3. What is the role of balcony solar panel
Compared to rooftop photovoltaic systems, balcony power plants have a limited amount of power generation. The main goal of the system is not to pursue maximum power output, but to generate solar electricity at a lower cost to meet the household's own electricity needs, reduce dependence on the grid, and thus reduce the household's electricity bill.
For example, a 300-watt solar system (with power inverter 2000) costs around 400 euros (as of August 2023) and can save around 50 to 100 euros per year on electricity bills. For larger systems with 600 watts, it is usually possible to save a household between 100 and 200 euros in electricity bills.
4. How much you can save with balcony solar panel
- Generation
The amount of electricity generated by balcony solar panel is related to its orientation, angle to the ground, location, and area insolation.
- Electricity consumption during the day
When solar power generation is available during the day, it is possible to further increase the self-consumption ratio and profitability of solar energy by scheduling when solar power generation is at its highest. Such a strategy can significantly reduce the need for customers to purchase electricity from the grid.
For example, consider the following questions: What devices need to run around the clock, and some common devices include refrigerators, routers, and heating equipment.
In addition, consider spreading the operating time of frequent home cooking and using appliances such as washing machines and dishwashers so they can run at different times of the day. For those who are barely at home during the day, one should consider choosing a solar power system configured with lithium battery.
This way, when excess energy is generated, you can store it for use at night or on cloudy days. With these power usage strategies, you can make better use of your solar power system and achieve greater energy savings and economic benefits.
- Grid tariffs
In the case of high electricity prices, choosing to install a balcony power generation system will speed up the return on your investment.
5. What you need to consider before buying balcony solar panel
● Use a new meter
The goal of plug-in solar systems is to reduce the user's dependence on mains. However, in some cases, more solar power may be generated than is currently needed, and the excess power is incorporated into the grid. In order to prevent meter reversal, a bidirectional meter needs to be installed.
Therefore, before installing a balcony PV system, check with the grid operator if the meter needs to be replaced. Information can be found by typing your place of residence into an internet search engine and searching for "grid operator".
● Installation
When installing solar panels, it is important to ensure that a secure assembly is carried out. Here are some considerations and recommendations:
- Installation height restrictions
This type of installation may not be carried out in accordance with architectural glazing standards without first obtaining a general building permit or individual approval.
- Special solar modules
Some special solar modules may be approved for use. These modules can be identified by a general building inspection.
- Installation requirements
The installation of solar panels must meet the structural and strength requirements of the building. They should be able to withstand a variety of weather conditions, including storms, etc. Make sure to use a connection material that is durable and suitable for outdoor use, and avoid materials that are fragile or not weather-resistant.
6. How to buy balcony solar panel
So how to buy balcony solar panel for a home solar PV system? Before buying, you need to clearly choose what power solar cell modules are. If the annual electricity consumption of a household is less than 2,500 kWh, usually 300 watts of solar modules are sufficient.
You can also consider power inverter 3000w. But if the demand for electricity is greater during the day, more is needed. If you use more than 2,500 kWh of electricity per year, it's usually worth considering two balcony solar panels.
Cost: In most cases, the purchase cost will be recouped in less than a decade. When purchasing, there are also possible shipping costs and delivery times to consider, as it usually takes a few weeks for the supplier to deliver the mini PV system.
7. Conclusion
This is a simple solar PV system. Balcony solar panel is photovoltaic power generation systems that are installed on balconies. Easy to install, plug and play. All you need to do is attach the system to the balcony railing and plug the system cable into the socket at home.
