There are as many advantages as using solar powered lamps. The primary advantage is that we do not need any facilities or networks. Because the transmission of the electricity line, such as the network, is always the work load and the user is in trouble. The second most important advantage is that you install the solar-powered lamp system, and perhaps for years you do not pay any extra maintenance charges such that it works on its own and goes out, so solar-powered lamps are inexpensive. It is very reliable because it is in a structure isolated from cables, it is very cheap and it is suitable for cutting and it can be regarded as features that the electricity you spend is obtained from the sun rather than your pocket.
