The energy crisis has sent home energy bills skyrocketing and more and more households are looking for ways to save money on their electricity bills. While many choose to install photovoltaic panels on the roof of their homes, what about those tenants or apartment owners who don’t have their own roofs? Photovoltaics, or the first choice. Using your own small balcony to build a mini PV power station, even on a small scale, can reduce ongoing electricity costs over time. maysun has put together this article for you, let’s learn about mini PV power stations on balconies!
What is balcony PV
Urban development of distributed photovoltaic, often limited by the roof resources, in order to build distributed photovoltaic power station, a variety of photovoltaic application model came into being. Balcony photovoltaic power generation is a new model that has recently emerged, which uses balcony resources to layout solar power generation system.
The advantage of installing balcony photovoltaic power generation is that no independent roof resources are needed, either in residential buildings or high-rise apartments. Without damaging the main structure of the building, the photovoltaic modules are laid at the balcony outside the house, and of course you can install them on the wall, terrace, garden, just a few pieces. Not only covers a small area, but also makes full use of the building resources, to achieve construction, environmental protection, energy saving, power generation, practical in one, cleaning and maintenance is also relatively easy.
What conditions do you need to meet to install balcony PV panels?
It is usually off-grid power generation. As long as your balcony faces south, you can build this “balcony power plant”, of course, it is also suitable for balconies facing southwest or southeast. The size of the system determines the performance and ultimately the cost, and the amount of power generated depends on the number of solar panels installed and the power level.
“Balcony power plants can be installed in a variety of ways, depending on the latitude of the location, the tilt angle of the panels, and the load-bearing capacity of the balcony. A common wall-mounted type is to tilt the panels parallel to the wall, or they can be placed directly in the middle of the balcony using wheeled racks, or installed as an overhanging canopy.
The electricity generated must be directed into a wall outlet; do not use extension cords or power strips. The Consumer Protection Association recommends that every family installing a solar PV system check their homeowners insurance coverage and ask if the PV system can be included in an existing insurance contract.
In January 2023, the German VDE proposes to simplify the threshold for the installation and use of balcony PV in the hope that this type of PV will be widely used in the future. A federal state has even decided to grant subsidies to allow residents to install mini solar systems on their balconies.
In Italy, the power is limited to less than 800w without having to show any authorization, but must comply with some regulations.
Advantages and disadvantages of balcony PV
The new model of balcony PV, compared to other rooftop projects, has both advantages and disadvantages in terms of installed capacity.
Advantages:
1. small size does not take up space, can be laid outside the house PV modules on the balcony, wall, etc.
2. low threshold, almost no management authorization required (some countries need to contact the apartment manager)
3. Solar panels with four-wheeled support, which can be moved and adjusted to fit the best direction of sunlight (available for camping)
4. Can be used in case of power failure
5. Easy to maintain and clean
6. Low cost
Installation of balcony PV has many advantages, but it also has some considerations: 1:
1. Small PV systems cannot guarantee to cover the daily energy needs of the whole apartment, and the small number of installations results in small power generation capacity
2. Wall-mounted solar panels require professional construction personnel and have a high risk factor for installation.
