Balcony solar systems are small-scale photovoltaic installations designed for compact spaces like balconies, patios, railings, or building facades. They offer plug-and-play convenience and self-consumption capabilities. This helps reduce reliance on traditional power grids.
Components of a Balcony PV System
Photovoltaic Modules: These are the core components of a balcony PV system, converting solar energy into electricity. A typical system includes 1-4 photovoltaic modules.
Microinverters convert the direct current (DC) generated by the photovoltaic modules into alternating current (AC) for household use. They offer high safety, efficient power generation, and strong reliability. Microinverters support connection to a small number of photovoltaic modules. This makes them well-suited for balcony photovoltaic system applications.
Mounting Brackets and Connection Cables: Mounting brackets secure photovoltaic modules, ensuring stable installation on the balcony. Connection cables link photovoltaic modules to microinverters, transmitting electrical energy.
Application Scenarios and Advantages of Balcony Photovoltaic Systems
Balcony photovoltaic systems are mainly deployed on balconies, terraces, courtyards, and street-facing commercial spaces. These locations often have unique architectural structures and limited installation space. As a result, the installed capacity tends to be small. For shops and villas, daytime electricity use is high, and rates are costly. The electricity from photovoltaic systems during the day can be largely consumed on-site. Balcony photovoltaic systems are very suitable and help users save on electricity costs.
Advantages and Solutions of Balcony Photovoltaic Products
With accelerating urbanization and limited residential space, balcony photovoltaic systems show great future market potential. For these applications, Growatt introduces the NEO series microinverters and the NEXA 2000 balcony photovoltaic storage integrated unit. These offer several advantages:
Low-Voltage Design
Arc flashes from high DC voltage are a main cause of fires in PV power stations. The DC side of balcony PV products uses a 60V low-voltage safety design. This eliminates the risk of high-voltage arcing on the inverter’s DC side at the source, ensuring household safety.
Module-Level MPPT Tracking
The NEO series microinverters feature 2-4 MPPT channels and are well-suited for complex rooftops. Each MPPT channel is connected to a single module. This ensures maximum power point tracking for modules with different installation angles and power ratings. Energy generation is thereby maximized.
Smart Monitoring
Built-in WiFi or RF modules allow instant connection by scanning a QR code. Integrated with Growatt’s smart control system, users can remotely monitor real-time power generation data.
Three tailored solutions are available to meet diverse user requirements:
Balcony PV Solution – Non-Backflow Scenario
This WiFi-enabled microinverter solution offers smart monitoring via WiFi connection. It is ideal where daytime electricity use is high and all PV power is fully consumed.
Balcony PV Solution – Anti-Backflow Scenario
The anti-backflow scenario utilizes RF version microinverters.
+ Grohome Manager-X + CT to enable intelligent monitoring and anti-backflow functionality.
Balcony Solar-Storage Solution – Anti-Backflow Scenario
For users needing energy storage, the NEXA 2000 balcony solar-storage system combines a photovoltaic inverter and battery storage. A single NEXA 2000 system covers power generation, storage, and consumption needs. This maximizes the use of green solar electricity. A wireless smart meter monitors reverse power flow. Through RF wireless communication, it regulates the NEXA 2000′s charging and discharging power to prevent backflow.
The NEXA 2000 also supports stacking up to three 2048Wh expansion battery modules. This wiring-free connection quickly scales system capacity to 8kWh, meeting diverse capacity needs.
