Solar energy is now considered the most efficient and renewable energy source known to mankind. With the development of different technologies, different uses of this renewable energy source are being discovered. The solar lamp is one of the most effective uses of the sun’s energy. It is also one of the fastest growing industries in the world.
The constantly increasing demand for these lamps and luminaires can be attributed to two factors:
* The need to cut costs
* Control pollution
There are many pros and cons associated with these lighting options. Some of the key benefits are as follows.
Zero Energy Costs: One of the biggest advantages of a solar lamp is the zero energy costs. Since these lamps and lights get their energy from the sun, they can work for free. It is therefore widely used in parking lots and other places where lighting is constantly required. It helps to save energy and costs.
Low Maintenance: These lighting systems are known to last a lifetime as they rarely require any type of maintenance or repair. These systems draw their energy from the sun and therefore charge themselves automatically every day. However, the panels of these systems must be dusted once a week to avoid dust build-up.
Eco-Friendly: It is also known to be eco-friendly as it does not involve the use of toxic chemicals or gases to generate energy. Because these lights get their energy from the sun, they are considered environmentally friendly and safe for humans.
No Wire: Another advantage of the solar lamp is that the lights do not contain any wires. Each individual light contains a rechargeable battery pack and a photovoltaic module. It can therefore be easily installed and rarely requires the need for a professional for installation.
Packed Sets: These lighting systems are available in pre-packed sets. Walkway lighting kits include rechargeable batteries, LED bulbs, PV panel and housing. The boxed sets are fairly easy to install and rarely require professional help.
Quick Installation: Solar lights are easy to install as they contain no wires or circuits. It involves only minor assembly and is therefore easy to install.
Although these lighting systems have a number of beneficial properties, they are not without disadvantages. The most common shortcomings or disadvantages are as follows.
Initial Cost: The initial cost of these lighting systems is quite high, but they require less maintenance and repairs. It is a huge investment to redesign the lighting systems.
Exposure to the Sun: The batteries in these lighting systems depend on the sun for energy, but sometimes climatic variations such as an overcast sky or a storm can prevent the batteries from charging. Therefore, these lighting systems are ideal for areas where there is a lot of sunlight.
Non-critical option: Due to these disadvantages, solar lamps can be used mainly for decorative purposes, and not for critical ones.
