Balcony System
Balcony System
A balcony solar system is a compact Solar System solution designed for urban apartments—unlike traditional rooftop systems (which need large open roofs and complex renovation), it installs directly on balcony railings/ceilings, uses low-voltage components (≤220V), and connects to home grids without major approval. KINGSUN’s version further optimizes for small spaces: single-module power 1-5kW, weight ≤5kg/㎡ (safe for balcony load-bearing), and plug-and-play design.As a leading Solar System Manufacturer, KINGSUN ensures high-quality components and reliable performance for every installation.
No Rooftop, No Renovation
“Installs on balcony railings/ceilings (no drilling into walls for most models) – suitable for renters (no damage to property) and homeowners (no need to apply for roof renovation permits). 90% of urban apartments in China/Europe can fit our 1-3kW system.”
Lightweight & Space-Saving
“Module weight ≤5kg/㎡ (e.g., 1kW system weighs only 8kg), well below standard balcony load-bearing limits (≥20kg/㎡). Single-module size 1200×600mm – fits balconies as small as 1.5㎡ (e.g., 1.2m×1.2m closed balcony).”
30-Min Quick Installation
“Plug-and-play design: Pre-wired connectors + magnetic mounting brackets. No professional electrician needed – follow the manual to install in 30 minutes (tested with 50+ apartment owners, average install time 28 mins).”
Low-Voltage Grid Connection
“≤220V AC output (matches home socket voltage) – no need for high-voltage grid approval (simplifies process from 1-2 months to 3-5 days in most cities). Compatible with home appliances (directly powers fridges, TVs, air conditioners).”
Closed Balcony
Adaptation Solution:Choose anti-glare modules to prevent direct sunlight from affecting indoor lighting. Install them on the outer side or top of the balcony railing.
Case Study: In a Shanghai apartment with a 1.8㎡ enclosed balcony, a 1.5kW portable system was installed, generating 1,800 kWh annually, covering the basic electricity needs of the living room and bedroom.
Open Balcony
Adaptation Solution: Select modules with IP67 waterproof rating to protect against rain, and install them on balcony railings or ground-mounted brackets.
Case Study: In a Guangzhou residential complex with a 2.5㎡ open balcony, a 2 kW embedded system was installed, paired with an energy storage battery, providing up to 4 hours of power during outages.
Q1: Can I install a balcony solar system in a rented apartment?
A1: Yes—choose our portable model (magnetic/hook mounting, no drilling). It’s detachable (takes 3 mins to remove when moving) and won’t damage the balcony, so you don’t need the landlord’s approval (we provide a “renter guarantee” to cover any potential damage).
Q2: How much electricity can a 1kW balcony solar system generate?
A2: 1200-1800 kWh/year (varies by region: 1800kWh in Guangzhou, 1500kWh in Shanghai, 1200kWh in Beijing). This covers 30-50% of a family’s monthly electricity use (e.g., powers a fridge + TV + 2 lights for 30 days).
Q3: Is the balcony solar system safe for my home?
A3: Yes—all components have VDE/UL safety certifications. The system has 5 protections: overcurrent, overvoltage, short circuit, overheating, and leakage. It automatically shuts down if there’s a grid fault, so it won’t affect home circuits.
