How to achieve high efficiency of solar panels
- May 02, 2018 -

What is solar efficiency?

Solar efficiency refers to the amount of sunlight that can be converted to useful electricity. Photovoltaic solar efficiency can be measured by looking at solar cell or solar panel efficiency. In simple terms, a solar panel consists of a set of solar cells that are adjacent to one another on the top of the backsheet and covered by glass. Solar cell efficiency refers to the amount of light that a single cell can convert into electricity, while the efficiency of a solar panel is the amount of light that the entire module can convert into electricity.


You should pay attention to the efficiency of the solar panel, because it represents the actual amount of electricity generated by the solar system. It is important to know that the efficiency of solar panels is generally lower than that of solar cells because the glass that covers the panels reflects some of the sunlight. In addition, the interval between cells also means wasteful efficiency.


Why is solar panel efficiency important?


As you might guess, the more efficient the solar panels, the better the results. High-efficiency solar panels will maximize your overall investment return because you will generate the maximum possible amount of electricity through the minimum number of panels. Therefore, you will need less roof space, less time and money to install them.


You may have concluded that high-efficiency solar panels will be more expensive than less efficient solar panels. The typical commercial solar module has an efficiency of 16.5%, which means that about one-sixth of the solar modules will actually be converted to electricity.


The challenge for solar panel manufacturers is to maximize the efficiency of solar panels while reducing production costs. The panel must be reasonably priced so that people can afford it, so while 16-20% of efficiency doesn't sound very tempting, it is still sufficient for home use. In fact, people who own such solar panels need more power than they do, so they can sell their surplus back to the grid. So after all, this number is pretty good! Get (so far) the most effective solar panels.


So... Solar panel efficiency is an important factor that needs consideration and hope that technological improvements will lead to more efficient solar panels. However, solar energy efficiency should not be the only issue that needs to be considered when deciding to purchase solar panels for household electricity. You should keep in touch with their well-served suppliers and be attractive in terms of value.


In the process of converting sunlight into electricity, the overheating of solar cells can cause a staggering loss of energy. This not only affects the efficiency of solar panels, but also reduces its service life. As the cells heat up, the efficiency decreases by about five percent for every increase in temperature.


Because ventilation or liquid coolant is still very expensive and not worth it, no cost-effective cooling mechanism has been found. The good news is that a group of researchers at Stanford University in California recently discovered that if a layer of silica glass with tiny pyramids and pyramid structures is placed on top of a silicon solar cell, the cell's operating temperature drops considerably. These silica glass and pyramid structures transfer unwanted heat to the atmosphere, eliminate unwanted infrared radiation, and cause the solar cells to remain cool, thus being more efficient.


Although we seem to have to wait many years to apply this technology to the roof, some people think that this model is not feasible in the real world, but we will be optimistic that this discovery will lead to the development of more solar panels but not Too expensive to convert solar energy into more popular and attractive home alternatives.
