From Balconies to Powerhouses: Depth Look at the Growing Adoption of Balcony Photovoltaic Systems
What is the Balcony pv power plant built in balcony
Balcony power plants built in balcony also known as a self-generation system, is usually installed on south-facing balconies, terraces, gardens, garages, small roof tops, fences, etc.
You can install this self-generation station where you live, even if you're a renter. Traditional PV systems require equipment to be installed on rooftops, which require enough available area and adequate support.
Balcony PV system avoid these restrictions, and make better utilization of space. Especially for tenants, its rapid installation and disassembly are more convenient.
By using a small plug-in solar power plant, you can produce your own solar power and be a model towards climate protection and energy transition!
With your small solar system, you can collect solar energy in minimal areas. Even if you move, just unplug the power plug and bring the mini solar system to your new apartment. It's so easy for you to move it .
The past, present and future of balcony PV industry
Background of the balcony PV industry
The concept of energy self-sufficiency is gradually penetrating into people's minds, and the demand for energy by urban residents is continuously increasing. However, roof space available for photovoltaic installation is scarce. Thus, traditional balcony solar have become very prevalent and have seen extensive construction. Therefore, the balcony solar system was born.
The present of the Balcony PV Industry
In recent years, Balcony PV Industry has been widely promoted and applied. For example, new legislation in Germany has spurred the development of balcony PV systems, and this figure is expected to continue to rise. All over the world, more and more countries and regions are incorporating balcony photovoltaic into their energy policy and have increased support for such projects.
At present, balcony PV system has becoming an effective way for families and businesses to save energy and reduce carbon emissions. However, at the same time, how to improve its power generation efficiency and reduce installation and maintenance costs have remained important issues that need to be resolved.
The future trend of the Balcony PV Industry
Balcony PV system is an innovative solution to address the limited rooftop resources in cities. Its main feature is that it can be installed in limited balcony space, making it suitable for residential buildings or high-rises. This form of PV power generation doesn't need separate rooftop resources, significantly improving the spatial utilization efficiency of solar power and also noticeably enhancing the popularity of solar power.
The installation subsidies of balcony PV system
Policies and subsidies for balcony PV vary in different countries and regions.
Germany's Balcony PV Subsidy Policy: The German government offers a series of subsidies for balcony PV, including financial subsidies for the energy storage part.
As of January 1, 2021, a new solar cell subsidy policy, the so-called "Green Deduction," has been implemented. This subsidy is given in the form of a 20% tax deduction and is likely to remain valid until 2024.
In addition, there are special time windows each year that provide additional subsidies. You need to check the eligibility conditions and application procedures on local websites, to make sure you are certain qualifications to receive the subsidies.
In Spain, commercial or industrial solar installations can enjoy a subsidy of 15%. If it's a small or medium enterprise and its in-house power is equal to or less than 15 kilowatts, then the subsidy can reach up to 45%. There are also corresponding subsidy policies for individuals. However, due to subsidy limitations, there are quotas. Not all users installing balcony photovoltaic systems can benefit from this subsidy. Starting early with balcony solar plant increases your chances of securing a quota.
Analysis and calculation of balcony PV power plants and income
Capacity experiment of the balcony solar power station
According to the Stecker Solar Simulator, a solar simulator for calculating investment returns, we can draw two conclusions.
Using the same data set — for a household of two people with an average annual electricity consumption of 2500 kWh, calculated at a rate of 33 euros/kWh, and with the solar power station installed at a 45-degree angle on the balcony railing — we conducted two comparative experiments.
1.The larger the micro-inverter outputs, the shorter the investment payback period.
2. The larger of battery capacity, the shorter of the investment payback period
