What Is A Solar Mounting System? A Complete Guide To Types And Features

When starting a solar power project, a critical component is the napelemes rögzítő rendszer—the structure that supports your solar panels.

This article explains the different types of solar mounting systems, their foundations, materials, and where each is best used. Whether you’re planning a new installation or looking to optimize your design, understanding these systems is essential.

What Is a Solar Mounting System?

A napelemes rögzítő rendszer is the structural base that holds solar panels in place. It’s engineered to match local conditions—such as ground strength, sunlight angle, and regional hazards like typhoons or heavy snow.

Without the right mounting system, solar panel performance and durability can be compromised.

Types of Solar Mounting Foundations

Concrete Foundation

A concrete foundation strengthens the mounting base. It includes three main types:

Block Foundation (置き基礎): Concrete blocks are embedded underground. Offers stability but incurs digging costs.

Strip Foundation (布基礎): Blocks are connected in a row, increasing strength and cost.
Mat Foundation (ベタ基礎): A single, connected concrete surface. Highest cost, but offers top stability.

Pile Foundation

Pile foundations use poles or screws embedded in the ground. Key types include:

Steel Pipe Pile (単管杭): Simple and cost-effective, but low in wind resistance.
Standard Screw Pile: Requires dedicated machinery. Stability depends on soil hardness.

Large-Flange Screw Pile (大羽スクリュー杭): Bigger blades offer stronger grip in soft soil.
C-Type Steel Pile: Inexpensive and easy to install, but weaker against vertical force.

Material Characteristics

Different materials offer varying performance:

Anyag	Characteristics
Stainless Steel	Rust-resistant and durable but heavy and costly
Aluminum	Lightweight and rustproof, but lower strength unless specially shaped
Galvanized Steel	Strong and corrosion-resistant (if coated), but heavy and expensive

Ground-Mounted Structure Types

Metal Roof Structures

Used on trapezoidal or standing seam roofs. Types include:

Flat (平置き): Simple and cost-effective.
Tilted (傾斜型): Increases sunlight exposure but costs more.

Flat Roof Structures (陸屋根)

Flat roof installations are common on commercial buildings. These use ballasted or fixed aluminum mounts to reduce roof load.

Solar Carport Structures

These mounts are installed on carport roofs, ideal for dual-purpose space:

Power vehicles via EV charging
Offset facility power costs

📌 Popular options:

Agricultural Solar Structures

Solar sharing systems allow farming and solar generation together. High-clearance poles (5–6m apart) leave space for equipment and sunlight.

How Height Affects Performance

Solar panel height affects:

Snow resistance: Too low and panels may be buried.
Shading: Tall grass or nearby objects can block sunlight.

📌 Suggested minimum height:

50 cm in general
100 cm in snowy areas

Choose the Right Mount for Your Region

Each project has unique conditions:

Soil condition: Affects pile vs. concrete foundation choice
Snow load / wind zones: Impact material and height decisions
Use case: Ground, roof, agriculture, or EV charging

For open land installations, the most common types are:
