Compact 4V 100mA Solar Cell Panel

Product Code : SCL-SK-12163

The 4V 100mA Solar Cell Panel is a compact photovoltaic teaching component used for demonstrating how light energy is converted into low-voltage electrical output. It is suitable for schools, colleges, STEM labs, physics practical rooms, electronics training, renewable-energy activities, science exhibitions, distributors and educational procurement buyers.

Product Description

The Compact 4V 100mA Solar Cell Panel from Science Lab Supplies is intended for practical demonstrations of photovoltaic electricity and basic solar circuit behaviour. The supplied product name confirms a nominal output of 4V 100mA, equal to a calculated 0.4 W at those stated values. Cell type, dimensions, terminal style and construction material must be confirmed before final catalogue publication.

This panel helps students observe the relationship between light intensity, polarity, voltage, current and load response. It can be used with approved low-voltage devices such as LEDs, small motors, buzzers, meters or rechargeable circuits where the load rating is compatible with the stated 4V 100mA output.

Key Features

• Nominal 4V 100mA output: suitable for low-voltage classroom photovoltaic demonstrations.
• Compact solar-cell format: easy to position under sunlight or an approved classroom light source.
• Photovoltaic learning component: demonstrates direct conversion of light into electrical energy.
• DC circuit practice: helps teach polarity, open-circuit voltage, load current and simple wiring.
• Calculated power reference: 4V at 100mA equals 0.4 W under the stated electrical values.
• STEM project use: suitable for solar cars, LED models, fan models, mini pumps and electronics projects where ratings match.
• Specification-dependent performance: output depends on light intensity, panel angle, load resistance and cell condition.
