Compact 4V 100mA Solar Cell Panel

Product Code : SCL-SK-12163

Compact 4V 100mA Solar Cell Panel (SKU SCL-SK-12163) is a photovoltaic panel rated at a nominal 4 V and 100 mA, about 0.4 W, for school and college experiments on solar electricity. With it, students can measure panel voltage and current and power LEDs, small motors or buzzers where the load ratings match. Science Lab Supplies manufactures the panel at its Plot 448, HSIIDC Industrial Area unit in Saha, Ambala, India, and quotes it without middlemen to schools, colleges, contractors and distributors.

Specifications

The panel's electrical ratings and fittings are listed row by row below. In short, it delivers a nominal 4 V at 100 mA, a calculated 0.4 W, and comes with leads, crocodile clips and a mounting base; actual output varies with light intensity, panel angle, load resistance and cell condition.

Applications and Experiments for the 4V 100mA Solar Cell Panel

The panel is a building block for solar practicals. Connected to meters and a variable load, it can serve as the cell in a simple solar cell characteristic kit for studying output against light level and angle; connected to a small load, it powers student-built LED, fan or pump models.

• Secondary physics: measuring voltage and current from a solar source, for example on the DC ranges of a Digital Multimeter.
• Senior secondary physics: solar cell characteristics, with the load stepped through a decade Resistance Box.
• B.Sc. and diploma electronics: open-circuit voltage, load current and polarity.
• STEM projects: solar cars and LED, fan or mini-pump models where the load suits a 4 V, 100 mA supply.

Do not connect the panel to mains electricity, short the terminals for long periods, bend it or use it with cracked cells.

Standard Scope of Supply

Each panel is supplied with connecting leads, crocodile clips and a mounting base, together with an activity guide and a storage box. Cell type, dimensions, terminal style and construction material for the panel quoted are confirmed on the quotation, and extra meters or loads can be added to the same order.

Packing, MOQ and Lead Time

Panels can be quoted one at a time or in quantities for a whole class. Each quotation gives packing, delivery time and price for the number requested, and solar LED, fan or pump models can be quoted with them by this school science kit supplier in India.

Science Lab Supplies is registered as an exporter with an Importer-Exporter Code and can ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. For class quantities, send a note from the contact page, enter the panels in the enquiry cart, or see the lab tender page when buying through a tender.

Frequently Asked Questions

What does 4V 100mA mean on a solar panel?
It is the nominal rating: about 4 volts and up to 100 milliamps in good light, or roughly 0.4 watts. In weaker light, or with a heavy load, the panel delivers less.

What can this panel power?
Small low-voltage loads such as an LED, a buzzer or a small motor, provided their voltage and current needs suit a 4 V, 100 mA source. Check the load rating before connecting.

Is Science Lab Supplies the manufacturer or a trader?
These panels are produced at the Science Lab Supplies unit in Saha, Ambala, India, so the company quotes them as their manufacturer and buyers receive each quotation directly from the maker.

How should the panel be handled?
Keep the surface clean and scratch-free with a soft dry cloth, avoid bending, dropping or wetting it, do not strain the leads or short the terminals, and store it dry between lessons.
