Functioning And Advantages:
A solar light makes use of a solar panel to create electric current, which is stored in a battery. The solar panel generates electricity by converting energy from sunlight that is incident upon it. You can use the energy stored in the battery to provide illumination in various settings, ranging from solar garden lighting to solar security lights.
Whether you want a solar shed light or solar patio lights, the technology behind the system is the same: a panel converts solar energy into electricity, which charges a battery. However, depending on the exact location where you want the light to be installed, it may be possible to have the panel in the same place.
For instance, unlike units for garden lighting, one for a shed may not have sufficient direct sunlight available to allow the panel to charge a battery. Therefore, the panel would have to be installed in a different place, most likely on top of the shed. Some minimal amount of wiring from the panel to the battery and lamp will be required.
However, considering the fact that sheds are often not included in the electrical wiring plan of the main house or building, this is not a disadvantage. In fact, the complexity and expenditure involved in drawing wires for a shed's lighting is far greater than what a simple solar shed light will require.
Besides this, solar patio lights and solar garden lamps offer large savings on power bills since they don't require an external power supply. This also makes them environment-friendly.
Regardless of the application, your main choices will be concerning the actual light emitter and the battery. In the former, you may choose from among incandescent bulbs, compact fluorescent lamps (CFL), or light emitting diodes (LED). Batteries are usually either lead-acid or nickel-cadmium types.
Incandescent bulbs are quite energy inefficient and consume a lot of power, draining batteries very quickly. CFLs are relatively much more efficient, while LEDs are by far the most efficient, radically reducing consumption of incandescent lights by as much as 80%. Unsurprisingly, LEDs are the most expensive of the lot and incandescent bulbs the cheapest. However, LEDs also last far longer than any other type of light and in the long run, are definitely cheaper to operate.
Nickel-cadmium batteries are more efficient and long-lasting than lead-acid batteries. As with the lights, nickel-cadmium batteries are also more expensive when you compare the cost. But again, they are better suited to the frequent charge-discharge cycles needed by a solar shed light and are cost-effective over longer time frames.
