What Is the Size of a 130 Watt Solar Panel A Practical Guide

If you're considering solar energy for your home, RV, or small business, understanding the physical dimensions of a 130-watt solar panel is crucial. This guide breaks down the typical size, weight, and applications of these panels—perfect for optimizing space and energy output.

Typical Dimensions of a 130 Watt Solar Panel

A standard 130-watt solar panel measures approximately 64 x 26 x 1.4 inches (162 x 66 x 3.5 cm). However, sizes can vary slightly depending on the manufacturer and technology used. Here's a quick comparison:

• Monocrystalline panels: Compact design, averaging 60 x 26 inches.
• Polycrystalline panels: Slightly larger, around 64 x 26 inches.
• Thin-film panels: Lightweight and flexible, up to 30% thinner.

Weight Considerations

Most 130W panels weigh between 18.5 to 22 pounds (8.4–10 kg). This makes them ideal for rooftops, RVs, and portable setups where weight matters.

Where Are 130W Solar Panels Used?

These mid-sized panels strike a balance between power and portability. Common applications include:

• Off-grid cabins and tiny homes
• RV and marine energy systems
• Small business backup power
• Agricultural sensors and irrigation

"A 130W panel can power a refrigerator for 4–6 hours daily when paired with a 200Ah battery—perfect for weekend cabins." – EK SOLAR Energy Analyst

Key Factors Affecting Panel Size

1. Cell Efficiency

High-efficiency monocrystalline cells (22%+) allow for smaller panels. For example, EK SOLAR's 130W model uses PERC cells to save 15% more space than conventional designs.

2. Frame Material

• Aluminum frames: Lightweight but rigid
• Frameless designs: 2–3 lbs lighter but less durable

3. Technological Advances

Half-cut cells and multi-busbar (MBB) designs improve energy density. Newer panels generate the same power in 5–8% less space compared to 2020 models.

Case Study: Off-Grid Installation

A family in Arizona installed six 130W panels (total 780W) on their 200 sq.ft cabin roof. The system:

• Occupied only 85 sq.ft of roof space
• Powered lights, a 12V fridge, and charging stations
• Reduced generator use by 90%

Brand	Dimensions (inches)	Weight (lbs)	Efficiency
EK SOLAR 130W	64 x 26 x 1.4	18.5	21.8%
Brand X	66 x 28 x 1.6	21.2	19.5%
Brand Y	62 x 25 x 1.2	17.8	20.3%

Optimizing Your Solar Setup

1. Measure available installation space
2. Calculate daily energy needs (in watt-hours)
3. Consider future expansion possibilities

FAQ: 130W Solar Panel Dimensions

• Q: Can I mount multiple 130W panels vertically?A: Yes, but ensure at least 4-inch spacing for airflow.
• Q: What's the smallest roof space needed?A>For a single panel: ~11.5 sq.ft (1.07 m²).
