solar radiation from the sun. The sun is a powerful energy, can be used by installing solar panels. You know it will provide enough energy for earth in one hour to meet global energy demand one year? However, we can only use 0. 001% of the energy. When it comes to renewable energy, solar energy is a hot topic for a reason. Although solar energy is widely criticized for expensive or inefficient, but it proved very useful - — Not only good for the environment, also beneficial to the economy. Because of various solar panels subsidies and rising demand, solar battery storage system greatly improve and complement the technology, make it become a more efficient and clean energy. The main principle of solar cells, the advantages and disadvantages; The advantage of solar energy. Renewable energy in all the benefits of solar panels, solar energy is really important renewable. It can be used all over the world every day. According to scientists, we can at least get the sun in 5 billion. 2. Reduce power generation electricity solar system to meet some of your energy demand, energy bill will drop. In addition, the solar energy can not only save electricity, also can be the rest of the power output to obtain electricity to the grid. Depending on the size and power consumption of the solar system. 3. Diversification of the application of solar energy can be used for various purposes. Solar energy can be used to provide energy for satellite in space, these satellites can't connected to the electricity grid. Solar energy can also be integrated into the building materials. Sharp company recently launched a transparent solar window. 4. Maintenance costs low solar system usually do not need a lot of maintenance. As long as they remain relatively clean, can wash a few times a year. In addition, with no moving parts, so there is no wear and tear. Inverter is usually the only need to replace parts in 5 to 10 years later, because it has been committed to convert solar energy into electrical energy and thermal energy ( Solar photovoltaic and solar thermal energy) 。 In addition to the inverter, you also need to cable maintenance, to ensure that the solar system run efficiently. Therefore, in the pay after the initial cost of the solar system, you can expect to spend less on maintenance and repair work. 5. Technology development of solar energy industry continues to develop, improve will strengthen in the future. The innovation of the quantum physics and nanotechnology could improve the efficiency of solar panels, solar system energy input double or even triple. The cost of the disadvantage of solar 1. Buy solar system of the initial cost is very high. This includes pay for solar panels, inverter, battery, electrical, and installation costs. Solar technology, however, is still in development, so the prices will surely fall further in the future. 2. Depends on the weather though solar still can collect in rainy day, but reduced the efficiency of the solar system. Solar panels on the sunlight gathered solar energy efficiently. Therefore, cloudy and rainy days will have a significant impact on energy systems. You should also consider not to collect solar energy in the evening. On the other hand, if you still need your water heating solutions work at night or in winter, hot plate is another factor.
