Longi 660 Photovoltaic Panel Dimensions Demystified

Longi 660 Photovoltaic Panel Dimensions Demystified

Understanding the Solar Workhorse

When considering solar installations, the Longi 660 photovoltaic panel often emerges as a top contender. This solar behemoth measures approximately 2,278mm in length × 1,134mm in width – roughly the size of three standard office desks placed side-by-side. With a depth of 35mm, these panels maintain a streamlined profile while packing serious energy-generating muscle.

Why Size Matters in Solar Arrays

• Roof Real Estate: Each panel covers about 2.58m² – crucial for calculating how many "solar tiles" your roof can accommodate
• Weight Considerations: Tipping the scales at ~35kg per unit, structural integrity becomes paramount
• Efficiency Ratio: Delivering 660W output, it achieves ≈21.3% conversion efficiency – like squeezing orange juice from 21% of the fruit's mass

The Goldilocks Principle in Solar Design

Recent installations in Arizona's Sonoran Desert demonstrate how these dimensions enable remarkable energy density. A 100-panel array covering 258m² generates enough electricity to power 40 average American homes – essentially creating a miniature power plant on your rooftop.

Installation Sweet Spot

• Commercial Edge: Warehouses love these panels – their size-to-output ratio slashes installation costs by 18% compared to smaller units
• Residential Hack: Ground-mounted systems using LR4-72HPH modules show 12% better annual yield in mid-latitude regions

Beyond Tape Measures: Hidden Dimension Factors

While you're busy calculating panel counts, don't overlook the invisible dimensions. The 1.5cm frame clearance requirement affects total system size more than most anticipate – it's like needing breathing room between marathon runners in a packed race.
