In front of a lot of information on solar energy, it is still plagued by some rumors, here are five you should not believe that solar misunderstanding.
1.solar energy only in warm regions
The average temperature of a region will not have too much of solar panels. In fact, the solar cell conversion efficiency at low temperatures would rise some. So, even if you live in cold areas, you still have enough sunlight in solar panels. Germany, the northern countries (Germany, the latitude is equivalent to China’s Heilongjiang Province) is known not to sunny, but it is the world leader in the use of PV in 2009, the installed capacity has more than 9800MW. Used by the solar panels can cover an area of over 2 million homes in the roof. So, next time you hear that, you can easily point out that high or low temperature latitude in this area does not mean you can not use solar energy.
2.The solar modules installed, you still need traditional fossil fuels as a backup source of energy.
Now almost all household solar cells can be connected to the grid. Electricity generated by solar panels in addition to domestic supply, the remaining power can be sent back to the grid. This actually means that the family can turn the meter backwards. More importantly, housing is still grid connected, solar cell at night or cloudy days, can have up to less than the maximum power emitted by power plants. If you install this grid solar power system, will not have to prepare a backup diesel generator, and China is still a lack of appropriate price subsidies.
3: Select solar energy to give up the life of modern comfort
Installed grid solar power system, still connected to your home network, and the issue of solar electricity you can offset a considerable portion of the power supply needs. This way, you do not need batteries can power day and night, while in the normal use of household appliances can also reduce a large portion of electricity expenses.
4: not ready for large-scale solar energy use
This is perhaps one of the most hazardous of the rumors because it makes many owners defer the installation of solar plan. Decades of research, billions of research funding has brought us a reliable solar power technology. At the same time, governments are encouraging commercial and residential solar power projects.
5: Manufacturing solar cells produces less energy than all the power it more than
Energy payback time (Energy Payback Time, EPBT) is a measure of solar energy generated using the process of repayment of the energy consumed in the manufacturing process time required. U.S. National Renewable Energy Laboratory (NREL) report shows that the cost of photovoltaic solar energy components to recover the time between 1 to 4 years, due to different type of battery (new battery EPBT CdTe less than 1 year). Taking into account the solar cells can continue to work for 30 years, PV systems can provide 26 to 29 years of zero-emission electricity.
