Germany Balcony Solar Project

The project is primarily aimed at apartment dwellers and small homeowners, utilizing balcony space to install solar panels for achieving self-sufficiency in clean energy.



Project Introduction

The Germany Balcony Solar Project is an innovative renewable energy solution that has gained popularity in Germany in recent years. This project is primarily aimed at apartment dwellers and small homeowners, utilizing balcony space to install solar panels for achieving self-sufficiency in clean energy. Since the summer of 2024, the balcony solar project has quickly become popular due to its simplicity, practicality, energy-saving, and environmentally friendly features, making it the preferred choice for many households to achieve energy independence and reduce electricity costs.

Project Details

The project is located in a typical apartment building in Germany.

The core of the project involves the efficient combination of solar panels, micro-inverters, and DC-AC wiring systems.

The solar panels are installed on the balcony, with micro-inverters responsible for converting DC power into AC power for household appliances. During implementation, the design is customized based on the balcony’s orientation, area, and sunlight conditions to ensure maximum power generation efficiency.

Applications

The balcony solar system is widely used in daily life. For users who work from home, the system can meet the power needs of computers, lighting, and other devices, reducing electricity costs. During sunny days, it can also provide power for high-energy appliances like washing machines, contributing to a green and clean energy solution. An optional micro-storage device can be added, allowing the system to release stored energy during the night or on cloudy days, further enhancing energy utilization and reducing dependence on the grid.

Main Equipment

The main equipment of the balcony solar project includes solar panels, micro-inverters, and DC-AC wiring. It uses high-efficiency TOPCon modules with high conversion efficiency and long lifespan. The system is equipped with a visual energy management system, allowing users to monitor the system’s operational status in real time.

Core products

Satellite Communication Energy Cabinet
Satellite Communication Energy Cabinet

The Satellite Communication Energy Cabinet is a PV energy storage cabinet from Highjoule Technology Group designed specifically for off-grid satellite communication sites. The system consists of PV modules, an MPPT solar controller, an LFP (Lithium Iron Phosphate) battery pack, a thermal management system, and a power distribution unit, forming a complete off-grid PV generation and energy storage system that provides stable power to satellite communication base stations. The system adopts a modular design and can be efficiently operated and maintained via local and remote monitoring. It supplies 48V DC and AC 120V–200V power to satellite and other industry communication equipment, supporting floor-standing and pole-mount installation.

Outdoor Battery Cabinet
Outdoor Battery Cabinet

The Outdoor Battery product line is centered on green low-carbon, high-efficiency, and intelligent coordination principles. It covers both indoor and outdoor configurations, with lithium batteries (or lead-acid batteries) forming battery energy storage cabinets. Each cabinet also houses environmental sensors, battery circuit breakers, battery cables, and thermal management accessories to form an integrated battery cabinet.

Hybrid Power System
Hybrid Power System

The Site Hybrid Power System is a next-generation multi-energy integrated power supply for 4G/5G base stations, communication equipment rooms, edge data centers, and outdoor compact sites. It breaks the traditional “single grid input, single DC output” architecture to achieve multi-source energy input + multi-voltage output + intelligent coordinated dispatch. At the site level, it accommodates grid power, PV, energy storage, diesel generators, and other sources, delivering a highly reliable, efficient, and simply deployable power framework for 5G equipment, transmission equipment, and IoT loads. Power range: 6 kW–36 kW; available in both 3U and 1U circuit breaker configurations.

Stacked-PV MPPT Solar Controller
Stacked-PV MPPT Solar Controller

The Stacked-PV MPPT Solar Controller is specially developed for PV capacity expansion at base station sites. Using a series-connection scheme, the system consists of PV modules, a stacked-PV MPPT controller, and a DC meter. Each PV string is series-connected to the controller, which steps down the module output voltage to −48V and injects it onto the rectifier output busbar to supply DC loads. Designed for communication base stations, it supports wall-mount and pole-mount installation. The product is available in outdoor and rack-mount versions.

Outdoor Hybrid Energy Cabinet
