Explaining the different types of solar panels
Solar energy after years of development, solar charging technology has also undergone great changes, from the initial polycrystalline silicon solar panels, monocrystalline silicon solar panels, semi-flexible solar panels to thin film solar panels, solar panels are becoming more and more mature technology, but also more and more relevant to the application of life, while the efficiency and effectiveness of charging has also been greatly improved, from the initial conversion rate of only 8% to the current conversion rate of up to SUNPOWER solar panels with a conversion rate of up to 24.2% have made solar charging popular in the next 3-5 years!
Polycrystalline solar panels are made from polycrystalline silicon solar cells arranged in different arrays to form photovoltaic modules of different powers to meet the electricity needs of different appliances. The production process of polycrystalline solar panels is similar to that of monocrystalline solar panels, but the photovoltaic conversion efficiency of polycrystalline solar panels is much lower, with a photovoltaic conversion efficiency of around 12% (Sharp Japan launched the world's highest efficiency polycrystalline solar panels with an efficiency of 14.8% on July 1, 2004).
The photoelectric conversion efficiency of monocrystalline silicon solar panels is around 15%, with the highest reaching 18%, which is the highest photoelectric conversion efficiency of all types of solar panels, but the production costs are so great that it has not been able to be used widely and universally in large numbers. As monocrystalline silicon is generally encapsulated in tempered glass and waterproof resin, it is robust and durable, with a life expectancy of generally 15 years and up to 25 years.
In terms of production costs, it is somewhat cheaper than monocrystalline solar panels, with easy material manufacture, savings in electricity consumption and lower overall production costs, hence the massive development. In addition, the service life of polycrystalline solar panels is shorter than that of monocrystalline solar panels. In terms of performance to price ratio, monocrystalline solar panels are also slightly better.
Sunpower solar panels, a semi-flexible solar panel that can be bent at around 45 degrees, are also currently the most efficient solar panels, with a conversion efficiency of up to 24.2%, and are lighter, thinner and softer than polycrystalline and monocrystalline solar panels, which are less likely to be crushed. In terms of light absorption, polycrystalline and monocrystalline can only absorb blue light, while sunpower solar panels can absorb red, orange, yellow, green, green, blue and purple seven colours of light, while visible light and different visible light can be absorbed, greatly enhancing the sensitivity of light absorption, its low light sensitivity is stronger, in indoor light there is a charging response, in the strong light of the bath can achieve charging, but the current will be smaller. For other types of solar panels, there is essentially no charging response.
SunPower not only offers the industry's more efficient solar panels, its solar panels are not only available in two options in terms of appearance, but also in three options at different levels of technology (from low to high conversion rates). The three series are called 205, 210 and 215, and the aesthetics of the solar panels have been taken into account while increasing the conversion rate. It breaks the pattern of traditional solar panel grid layout and is more aesthetically pleasing when applied to solar charging digital products, so the solar charger products applied by sunpower solar panels are more popular among enthusiasts, such as the third generation of high sensitivity solar panels used by the haogood brand 28W quantity solar charger, which is well received by enthusiasts.
With the development of solar energy application digital products, flexible thin film solar panels with its small weight, extremely thin, bendable, simple manufacturing process and other advantages have also been certain applications, the current domestic Hanergy as the representative of the thin film solar panels, widely used in solar folding bag, solar backpack, solar charging paper, solar tile, etc.. Although the advantages of thin-film solar panels are outstanding, the photoelectric conversion efficiency of thin-film solar panels is not as high as the conversion efficiency of traditional crystalline silicon cells. The improvement of the conversion efficiency of thin film solar cells is the main direction of continuous research in the solar technology sector, and the current conversion efficiency is around 12%-16%. So in comparison with SUNPOWER solar panels, we found that for the same power of solar charger, the area using SUNPOWER solar panels is more than one third smaller than that of thin film. So in terms of solar charging efficiency, the SUNPOWER solar panel charger will have a better charging speed, but the lightness of the thin film solar charger will be better.
Through the above interpretation, each type of solar panel has its own advantages and shortcomings, but from the end application point of view, SUNPOWER solar panel chargers are more suitable for application on solar folding bags, while thin film solar panels can be used on solar backpacks because they can be bent at a large angle is quite perfect, and I believe that the majority of donkeys through in-depth understanding will be better to choose their own preferred Solar charging digital products
