Read the following text and answer the question. Solar energy is derived from the sun’s radiation. The sun is a powerful energy source, and this energy source can be harnessed by installing solar panels. Many people are in favor for solar energy for it is renewable. However, it is also widely criticized for being expensive or not efficient. The most important reason for those who are in favor for solar energy that it is a truly renewable energy source. It can be harnessed in all areas of the world and is available every day. We cannot run out of solar energy, unlike some of the other sources of energy. Solar energy will be accessible as long as we have the sun, therefore sunlight will be available to us for at least 5 billion years when according to scientists the sun is going to die. In addition, solar energy systems generally don’t require a lot of maintenance. We only need to keep them relatively clean, so cleaning them a couple of times per year will do the job. Also, the technology in the solar power industry is constantly advancing and improvements will intensify in the future. The pros believe that innovations in quantum physics and nanotechnology can potentially increase the effectiveness of solar panels and double, or even triple, the electrical input of the solar power systems. On the other hand, many people say the initial cost of purchasing a solar system is fairly high. This includes paying for solar panels, inverter, batteries, wiring, and for the installation. It’s also known to take a lot of space as the more electricity we want to produce, the more solar panels we will need. Solar PV panels require a lot of space and some roofs are not big enough to fit the number of solar panels that we would like to have. To conclude, solar energy can be a potential alternative energy if there is a method of reducing the initial cost and saving space. Otherwise, there will always be pros and cons to the idea of solar energy installation. What is the text about?
