Understanding the 690W Photovoltaic Panel Dimensions

When planning a solar energy system, one burning question often arises: "What size is the 690W photovoltaic panel?" Let's cut through the noise. A typical 690W solar panel measures approximately 2279×1134×35 mm (length × width × thickness). But wait – size isn't just about physical dimensions. Let's unpack what this means for your energy needs.

Key Specifications at a Glance

• Power output: 690W
• Efficiency: 21.5%+
• Weight: ~35 kg
• Cell type: Mono PERC half-cut

Why Panel Size Matters in Solar Projects

Think of solar panels like puzzle pieces – their dimensions determine how many you can fit on a roof or ground mount. For commercial installations, the 690W panel's high power density means:

• 15% fewer panels needed compared to 550W models
• Reduced installation labor costs
• Optimized space utilization

Case Study: Warehouse Installation

Panel Type	Quantity Needed	Total Space
550W	120	1,200 sq.ft
690W	95	980 sq.ft

This 18% space saving translated to $8,500 in reduced mounting system costs.

Industry Trends Driving High-Wattage Panels

The solar industry is racing toward TOPCon and heterojunction technologies – but why? Higher efficiency panels like the 690W model address three critical needs:

1. Land scarcity in urban installations
2. Demand for faster ROI
3. Grid parity challenges

Fun fact: A single 690W panel can power a refrigerator for 40 hours! Now that's what we call energy density.
