Solar Panel

A solar panel, also known as a photovoltaic module, is a device that directly converts sunlight into electrical energy. It provides renewable energy support for robot chassis, reducing energy consumption costs and extending range through the roof or chassis. Its core principle is based on the photovoltaic effect of semiconductor materials: When photons strike the surface of a semiconductor, the energy is sufficient to excite electrons and form a current, generating direct current (DC).

Advantages of Solar Panels

Extended Battery Life

On sunny days, solar panels can generate an average of 50-150Wh of energy per day (depending on power output and sunlight intensity), reducing the frequency of charging.

Reduced Energy Costs

By utilizing solar energy to replace grid power, solar panels are ideal for deployment in remote areas (e.g., agricultural robots, outdoor inspection robots, logistics delivery robots, etc.).

Environmental Benefits

Zero carbon emissions, compliant with ESG (Environmental, Social, and Governance) standards.

Core Components of Solar Panels

Solar panels consist of the following key components, which work together to achieve efficient photovoltaic conversion and long-term stability:

Solar Cells: The core components that directly convert light energy into electrical energy.

Glass Layer: Protects the cells from mechanical damage and environmental corrosion while ensuring high light transmittance (>90%).

EVA Film: Bonds the cells, glass, and backsheet, providing insulation and cushioning protection.

Backsheet: Blocks moisture, UV rays, and mechanical impacts, providing electrical insulation.

Aluminum Alloy Frame: Secures the structural components, enhancing wind pressure resistance and load-bearing capacity (2,400 Pa wind pressure resistance, 5,400 Pa load-bearing capacity).

Junction Box: Collects current and connects to external circuits, with built-in diodes to prevent reverse current (“hot spot effect” protection).

Applicable Environments

The application of solar panels in robot chassis requires precise matching of component types and system design based on environmental characteristics. Example scenarios:

Agricultural plant protection robots

equipped with solar panels continuously recharge while working in the fields, increasing the duration of a single task by 30%.

Outdoor inspection robots

equipped with sun-tracking gimbals increase power generation by 40% and can still maintain 12 hours of battery life in desert environments.

Desert exploration robots

equipped with 300W monocrystalline silicon modules + tracking systems generate an average of 1.5 kWh per day, maintaining 85% power generation efficiency at 50°C, and can operate continuously for 7 days without manual charging.

Logistics delivery robots

use 200W flexible solar panels, generating an average of 0.8 kWh per day, with a 25% increase in runtime in cloudy conditions, and achieve fully automated charging via wireless charging.

Factory inspection robots

are equipped with 150W monocrystalline silicon modules, maintaining 75% power generation efficiency at 60°C in factory workshops. Combined with lithium-ion batteries, they can perform continuous inspections for 12 hours, reducing the need for human intervention.
