| Details: | Solar powered light box is a relatively simple concept. In a basic way, the system operates like a bank account. Withdrawals from the battery to power the light source must be compensated for by commensurate deposits of energy from the solar panels. As long as the system is designed so deposits exceed withdrawals on an average daily basis, the battery remains charged and light source is reliably powered.
The key to solar outdoor light box is the solar power pack, which houses photovoltaic solar panels, a proprietary microprocessor control system, and batteries. This is attached to specifically designed lights having super reflectivity and high energy ballasts. . The sun provides a direct source of energy to the solar panel. . The battery is recharged during the day by direct-current (DC) electricity produced by the solar panel. . The light source is powered by the battery each night. . Electronic controls are used between the battery, light source and solar panels to protect the battery from overcharge and discharge, and to control the timing and operation of the light. How does solar power work? In principal, it's simple. A solar panel converts light to electricity. During daylight, even on cloudy days, this "solar generator" (solar panel) charges long-life batteries, which store the energy until needed. Thus, the energy of the sun is harnessed to product power. In practice, of course, solar outdoor lighting is a little more complex. In addition to large capacity batteries and solar panels, the system also incorporates sophisticated proprietary charge regulators, which stop the flow of solar generated electricity when the batteries are fully charged, and then resume charging when more power is needed.
