Solar energy utilization is one of the effective ways to solve current energy and environmental problems. Among various energy conversion forms, electric energy has the advantages of clean, convenient, easy to store and transport, so photovoltaic conversion has become a major solar energy utilization method.
When under the sun, the principle of solar cell phone charger is to convert light energy into electrical energy and store it in the built-in battery through the control circuit. It can also directly charge mobile phones or other electronic digital products with the electrical energy generated by light energy, but it must be based on sunlight. Depending on the luminosity, in the absence of sunlight, it can be converted from alternating current to direct current and stored in the built-in battery through the control circuit.
120 watt folding solar panel
Solar panel (Solar panel) is composed of one or more solar cells, by absorbing sunlight, the solar radiation energy is directly or indirectly converted into electrical energy (direct current) through photoelectric effect or photochemical effect, mainly used for solar power generation System power supply.
The flexible foldable photovoltaic panel independently developed by SCIENTEK ELECTRICAL is made with the latest fabric technology, which can be folded multiple times, reduces space occupation, and is convenient to carry. It is suitable for emergency rescue, travel, in-car charging, military and other special occasions.
Packaging materials: TPT (ORPET), EVA, semi-flexible battery sheet, soldering tape, junction box.
solar power panels: folding solar panels
When the light irradiates the surface of the solar cell, part of the photons are absorbed by the silicon material: the energy of the photons is transferred to the silicon atoms, causing the electrons to transition, becoming free electrons, gathering on both sides of the PN junction to form a potential difference. At this time, under the action of this voltage, a current will flow through the external circuit to produce a certain output power.
Monocrystalline silicon: conversion efficiency is 15~18%, service life is 20-25 years, good stability, black, four corners are arc-shaped; polysilicon: conversion efficiency is 10-15%, service life is 20-25 Years, good stability, dark blue, with patterns on the surface, and square corners.
