A new type of solar panel made up of 40 tubes that resemble light sticks was introduced. This method of replacing flat plates with tubes effectively solves the problem of the direction of the sun's incident direction.
Solar energy is a low-cost and easy-to-operate power generation method. However, the practicality of this technology is not yet fully mature. One of the major problems is that if the sun is in different orientations, if the sun does not shoot in the direction of the solar panel, Then the cost of supplying solar systems for a family will increase significantly.
In order to solve this problem, a company based in California has developed a new type of solar panel that is specially designed to deal with the problem of sun's incident direction change.
The standard solar panel is a combination of photovoltaic cells made of silicon, somewhat similar to a computer's chip. These cells absorb the photons in sunlight and then convert this energy into electrons and form a current loop. Solydra is a solar energy manufacturing company that uses the unique and unique ways of manufacturing photovoltaics, like First Solar, Nano Solar, and Global Solar. Because these solar panels use less material, their cost is also lower. More importantly, these companies also put steel, glass and plastic in the bottom of the solar panel. The use of these materials further reduces the cost of the product.
The most effective part of the new thin-film solar devices produced by these companies is CIGS (Copper Indium Gallium Selenide). Although this material is inferior to silicon in converting sunlight into electricity, it has many advantages such as low cost and flexibility.
The Sorrera company covered a layer of glass in the CIGS, and then placed it in a sealed glass tube at the bottom. This tube looks somewhat like a light stick, and 40 such tubes are combined into one solar panel. The use of tubes instead of flat plates allows the device to absorb sunlight as much as possible, including diffuse light from all directions. Even the light reflected from the roof can't be ignored. In addition, the traditional solar panels must be placed obliquely and should be careful not to cover the adjacent solar panels, and the tubular solar panels can be placed horizontally over the entire roof. At the same time, solar panels are also very light, which makes them easier and faster to adapt to the surrounding environment. As for economic considerations, Soredra estimates that the installation cost of this new solar panel will be half that of conventional solar panels.
In the face of the US 30 billion square feet of rooftops, Solardrey’s CEO Chris Gronet is ambitious. “These roofs are large enough for the company’s products to provide 15 billion kilowatts of electricity. Enough to supply 16 million families."
