In the face of a lot of information about solar energy, people will still be troubled by some rumors. One of the goals of Love PV is to be a solar rumor terminator to help you eliminate the incorrect understanding of solar energy. Here are 5 solar rumors you shouldn't believe. Here are 5 solar rumors that you shouldn't believe, focusing on the cnbeta users' questions about the energy emitted by solar cells that cannot compensate for the energy consumed by solar cells.。
In the face of a lot of information about solar energy, people will still be troubled by some rumors. One of the goals of Love PV is to be a solar rumor terminator to help you eliminate the incorrect understanding of solar energy. Here are 5 solar rumors you shouldn't believe。
Gossip 1: Solar energy is only suitable for warm areas. The average temperature in an area does not have much impact on solar panels。
In fact, the conversion efficiency of solar cells will increase at low temperatures. So even if you live in a cold area, you still have enough sunlight to shine on the solar panels. Germany, the northern country (Germany's latitude is equivalent to China's Heilongjiang Province) is not known for its sunny sunshine, but it is the world leader in the use of photovoltaics. In 2009, the installed capacity has exceeded 9800MW. The panel area used can cover the roof of more than 2 million residential houses。
So, the next time you hear this, you can easily point out that high latitude or low temperature does not mean that solar energy cannot be used in this area。
Rumor 2: After installing solar modules, you still need traditional fossil fuels as backup energy。
Almost all current home solar cells can be connected to the grid. In addition to the electricity generated by the solar panels, the remaining electrical energy can be sent back to the grid. This actually means that the electricity meter at home can be turned upside down. More importantly, the house is still connected to the grid, and it can also use the power generated by the power plant when the solar cell does not reach the maximum power at night or on cloudy days。As long as you install this grid-connected solar power system, you don't need to prepare a spare diesel generator. (At present, there is still a lack of corresponding electricity price subsidy policy, FiT)。
Gossip 3: Choosing solar energy means giving up modern and comfortable life.
After installing the grid-connected solar power system, your home is still connected to the grid, and the electricity generated by the solar energy can offset a significant portion of your demand for grid power. In this way, you can use the battery to stay up all night without using a battery, and you can reduce the cost of a large part of the electricity while using the household appliances。
Gossip 4: Solar energy is not ready for large-scale use This is perhaps one of the most damaging rumors, as it has caused many homeowners to suspend plans to install solar energy. After decades of research, billions of research funding has brought us reliable solar power technology. At the same time, governments are encouraging commercial and residential solar power projects。
Rumor 5: Manufacturing solar cells consumes more energy than it can produce.
Energy Payback Time (EPBT) is a measure of the amount of time it takes to consume energy during the manufacturing process of solar cells. The National Renewable Energy Laboratory (NREL) report shows that photovoltaic solar modules recover energy costs in 1-4 years, depending on the type of battery (the latest CdTe battery EPBT is less than one year). Considering that solar cells can last for 30 years, photovoltaic systems can provide zero-emission electricity for 26 to 29 years. Have you heard more rumors about solar energy?
