1, the use of solar thermal energy, such as solar water heaters, to use more current but also more widely;
2, solar power, solar energy utilization is the key research areas, the popularity of the major obstacles:
①   photoelectric conversion of the silicon used to complete the high cost of photovoltaic cells, conversion efficiency is low, life is short;
②   batteries used to store electrical energy costs are high, life is limited, causing environmental pollution.
Foreign power networking solutions using energy storage problem, not the battery storage power, direct power supply, the effect is very good, but need to scale, and coordinated management of government intervention. Silicon photovoltaic cell technology is the rapid development and advancement. Currently the main use of solar power is also difficult to obtain in some areas or other places of power resources.
