Summary: This article explores the dimensions, efficiency, and real-world applications of 340Wp photovoltaic panels. Learn how their size impacts solar energy projects for residential, commercial, and industrial use, with actionable insights and data-driven comparisons.

What Makes 340Wp Solar Panels a Popular Choice?

With the global solar market projected to grow at 6.5% CAGR through 2030, mid-power panels like 340Wp units strike a balance between space efficiency and energy output. These panels typically measure around 1.9m x 1.0m – roughly the size of a standard door – making them versatile for rooftop installations.

Key Specifications Comparison

Practical Applications Across Industries

• Residential Rooftops: 10-15 panels can power a 3-bedroom home
• Agricultural Use: Water pumping systems requiring 3-5kW capacity
• Commercial Buildings: Parking lot canopies with 50-100 panel arrays

Consider this: The average U.S. household uses 10,632 kWh annually. A 340Wp system covering 60m² roof space could meet 80-90% of this demand in sunny regions. Not bad for panels that occupy less space than a compact car!

Installation Pro Tips

1. Allow 15-20cm clearance between rows for maintenance
2. Use tilt angles matching your latitude ±10°
3. Combine with micro-inverters for shaded areas

Why Choose 340Wp Panels Over Other Options?

While 400W+ panels dominate headlines, 340Wp models offer three distinct advantages:

• Easier handling (22-24kg vs. 28-32kg for high-wattage panels)
• Better compatibility with older racking systems
• Reduced voltage drop in long string configurations

As solar installer Mike Chen from Arizona notes: "For retrofit projects with space constraints, 340W panels often provide the best watt-per-dollar ratio. Their size fits most existing mounts without structural upgrades."

Frequently Asked Questions

How many 340Wp panels do I need for a 5kW system?

Typically 15 panels (15 × 340W = 5.1kW), accounting for 14-16% system losses.

Can these panels withstand harsh weather?

Most 340Wp models carry 25-year performance warranties and can endure 2400Pa snow loads – equivalent to 4 feet of wet snow.
