Who Needs This Information and Why?

If you're researching 405W photovoltaic panel specifications, you're likely a solar installer, project developer, or an eco-conscious homeowner. This article breaks down technical details while aligning with Google's search algorithms—think of it as your GPS for navigating solar panel efficiency and market trends.

Key Features of 405W Solar Panels

• Efficiency Range: 20.5%–22.3% (industry-leading for mid-power modules)
• Cell Type: Monocrystalline PERC with half-cut cell technology
• Temperature Coefficient: -0.34%/°C (better heat tolerance than polycrystalline panels)

Technical Breakdown: What Sets 405W Panels Apart?

Let's cut through the jargon. A typical 405W panel measures 1.8m x 1.1m—compact enough for residential roofs yet powerful for commercial arrays. The secret sauce? Bifacial design that captures reflected light, boosting output by up to 25% in snowy or sandy environments.

Industry Trends Shaping Solar Technology

The solar world's buzzing about TOPCon cells and microinverter integration. While 405W panels already outperform older 350W models, manufacturers are now testing n-type silicon substrates that could push efficiencies beyond 24% by 2025.

Real-World Application: Case Study

A Midwest farm replaced 120×300W panels with 80×405W units—same energy output, 33% less roof space used. Now that's what we call working smarter, not harder!
