Be aware with solar panels quality With a growing photovoltaic sector and with photovoltaic systems for self-consumption and grid connection increasing every day, it is essential to know what we must demand from a solar panel to ensure good quality and avoid being deceived by dishonest manufacturers. The reality of solar panel quality Sales of photovoltaic solar modules have been growing at record levels in recent years, but we must be very cautious when choosing one brand or another. [...]
SolarWorld German solar panels will supply 60MW to Turkish market SolarWorld, the German manufacturer of photovoltaic modules based on PERC monocrystalline technology, will supply a total of 60MW during the first half of 2018 to its strategic partner in Turkey, the EPC company Inosolar. In this way, the German solar panel brand confirms its complete recovery after the insolvency process that went through months ago. The signing of the supply contract took place last week, during an Inosolar visit [...]
How solar panels works - The basics ones Introduction: When the photovoltaic cells of the pv panels are illuminated while they are connected to an external load, they worka as a generator of energy and generate current and voltage values that are variable depending on the temperature and irradiance (magnitude that describes the radiation or intensity of solar illumination that reaches us as an instantaneous power per unit area, W / m2 or [...]
What is the function of Junction Box and Bypass Diodes in solar panels? Junction Box: It is located at the back of the solar panel, from where the interconnection terminals come out. In this box are marked the positive and negative output of the pv panels and inside it, protected with silicone, are placed the protection diodes (bypass) of which we will talk next. As an example, an image of the SolarWorld solar [...]
How is compossed a solar panel? The manufacturing process of pv solar panels is composed of several phases, in today's article, we continue with the previous article, about the solar cells, and describe the process of rolling, curing and framed. Lamination and curing The rolling materials are: EVA (Ethylene-Vinyl-Acetate): which is the encapsulant. Tedlar: is a material made up of three layers Tedlar-Polyester-Tedlar, is responsible for the tightness of the solar module by [...]
Connection of cells in pv solar modules The manufacturing process of a photovoltaic module is composed of several phases, in today's article, we will see two of them, the taping and the interconnection between the solar cells. Cell taping: The front grid of the cells is composed by the "fingers", which are the ones that collect the photogenerated current in the cell, and the "bus" that is the current collector where all the fingers are [...]
Today's article is aimed at those who are starting to enter into the world of photovoltaic energy and need information about the types of solar panels that are most commercialized in the current photovoltaic market.
