Understanding the Size and Applications of 380W Photovoltaic Panels

Why Panel Size Matters in Solar Energy Systems

When planning a solar installation, the 380W photovoltaic panel size becomes a critical factor for both residential and commercial projects. These panels strike a balance between high energy output and space efficiency, making them ideal for rooftops or ground-mounted systems. But how do their dimensions compare to other options, and what makes them a smart choice? Let’s break it down.

Key Dimensions of a 380W Solar Panel

A typical 380W panel measures approximately 2.1 meters in length and 1.0 meters in width, with slight variations depending on the manufacturer. Here’s what you need to know:

  • Surface area: ~2.1 m² per panel
  • Weight: 22–25 kg (easy to handle during installation)
  • Efficiency: 19–21% (higher than standard 350W models)

Case Study: Rooftop Installation in Urban Areas

In a recent project for a mid-sized warehouse in Germany, 120 units of 380W panels were installed across 250 m² of roof space. The system generated 54 MWh annually, reducing grid dependency by 78%. This success highlights how the compact 380W photovoltaic panel size maximizes limited spaces.

Panel WattageDimensions (m)Annual Output per Panel
380W2.1 x 1.0520–550 kWh
350W1.9 x 1.0480–500 kWh
400W2.2 x 1.1560–590 kWh

Industry Trends: Bigger Isn’t Always Better

While 400W+ panels dominate headlines, the 380W photovoltaic panel size remains popular due to its versatility. Emerging technologies like bi-facial modules and PERC cells enhance performance without increasing dimensions. For example, dual-glass designs now boost durability by 30% while maintaining the same footprint.

FAQ

Q: How many 380W panels fit on a 30 m² roof? A: Approximately 14 panels, accounting for spacing and mounting hardware.

Q: Do higher-wattage panels reduce installation costs? A: Yes – fewer panels mean lower labor costs, but balance this with roof load capacity.

Q: What’s the lifespan of a 380W panel? A: Most degrade by only 0.5% annually, maintaining 85% output after 25 years.
