Solar Energy may be having a lot of benefits, but it is also not something that is free of problems. It has multiple benefits which does outweigh the problems, but the problems highlighted here are the factors that is causing a hindrance to bring solar energy to an international scale and to use it effectively.
Whatever benefits that have been mentioned about solar energy till now are just predictions of what the Earth could gain by its implementation. It doesn’t really have true large scale success stories to boast about.
Integrating a solar energy system into a society is a very costly affair for a government and if it happens to be a developing country, one can easily forget solar energy. Governments are not ready to give up the infrastructure they already created for fossil fuel technologies and will not easily take up an amount for solar infrastructure.
This is a sad but core reality of using solar energy. The manufacturing of equipments itself is a business that very few dare to invest in, considering the stubborn unwillingness to give up fossil electricity.
Again comes the dreaded pollution. Not only does this damage the environment, it also damages the photovoltaic cells that would be used to harness solar energy. Exposed to areas to cloudy or polluted areas, solar energy cannot perform its best. This too is a limitation which scientists have tried to tackle with. They have come up with latest designs that helps to overcome such problems and hopefully the technology will get better to tackle the worst affects.
Solar Energy devices require large, spacious areas to be installed, and though it is good for rural areas, it is difficult to adjust it in a crowded urban city. There would be pollution plus clouds plus less space.
Mild Weathered Countries
As stated earlier solar energy requires strong sunlight, therefore it is best only for countries that are typically very hot. For European or surrounding countries, it is not very helpful. These countries are usually quite cloudy and rainy and even if they use solar energy they need very strong panels and often quite a lot of them. Again problem with panels is they require large empty space and urban cities cannot afford that kind of space.
Solar energy cannot be accessed during the night time and therefore extra equipments or batteries that will store this energy will be required. When energy is converted from DC to AC, a lot of energy itself is lost during the process and to support that loss, powerful grids have to be installed. At times a complementary solar energy station is also required to provide with the required energy during bad weather or during night time.
Solar energy can only then be affective when all these issues are cleared. The time required for fixing the problems would require at least a quarter or half of a century. Hopefully by the next century, solar energy may be affective enough, as right now, fossil fuel still rules the day with all its might.
