HSINCHU, Taiwan – Big Sun, a Taiwanese solar company, is taking big steps to produce solar systems that track the sun’s movement and produce more electricity than the average solar power system.
The result of the company’s work is that one day these systems will generate power on a utility scale and for the individual homeowner.
According to the company, for solar to achieve “grid parity” or equal importance for power production as fossil fuel power plants, photovoltaic (PV) systems to be as efficient as possible, meaning they must generate as much power from as much sunlight as possible. To meet this goal, solar tracking has been seen as vital to the efficiency of a system.
In other words, the most efficient way to get the most sunlight is to have solar panels track, or move, with the sun as it moves across the sky.
The main difference between solar trackers and fixed-tilt solar systems is that the modules of solar trackers can change their tilt angles at different times of the day to maximize power generation.
Fixed-tilt systems lose power-producing sunlight as the sun moves away the direction the system is pointing.
In most cases solar panels in the Northern Hemisphere face south, and the angle of the panels depend on other factors such as the building location and local regulations. Either way, as the sun moves across the sky during the day and away from the tilt of the panels, the fixed-position solar panels produce less power.
This is where Big Sun, a solar energy company founded in Taiwan comes in. Just last week, Big Sun announced an exclusive, innovative duel-axis tracking system, the iPV Tracker, that is able to smart track the sun’s movement through the sky and is proven to increase annual power generating efficiency up to 50 percent verses fixed-tilt systems, even reaching 100 percent power increase in high latitude areas.
And while the system is primarily a utility-scale system, it will no doubt be developed for individual consumers at an affordable price in due time.
For the moment, the utility scale system offers many benefits for any community or utility moving into the solar market. The best reason for using this system would be that it enhances the power grid to make up for shortfalls during peak load times. Moreover, iPV Tracker, with its self-sufficient power operation, is able to maintain a stable rate, which a fixed tilt system cannot beat.
Furthermore, iPV Tracker appears to the only PV system to contend against acts of nature.
With its exclusive characteristics it can re-orient itself in response to natural calamities such as hurricanes, snowstorms, sandstorms and floods. In all conditions the company says it operates and generates power without loss.
Summer Luo, chairman of Big Sun Group, says the iPV Tracker is designed for systems to continuously generate power throughout the whole daytime period and is able to supply power according to the daytime load curve.
“iPV Tracker is a high beneficial dual axis tracking system that brings out the efficiency and brings down the cost of your PV plants,” Luo said. “Increased investment will return multiple benefits. All in all, iPV Tracker is the highlight of Taiwan, stands alone in the renewable energy space, and has earned acclaim.”
Big Sun was founded in 2006. Its core business is focused on the design, production, and sale of high-quality solar products. Big Sun’s main products include 6″ mono-crystalline silicon solar cells, the iPV Solar Tracker and the web-based iPVita monitoring & control system. The current conversion efficiency of Big Sun’s 6″ mono-crystalline silicon solar cell is 20.0% (60-cells module with up to 290 watts power). Based on its extensive product lines, Big Sun can offer vertical integrated PV power system solutions.
