SUNGOLDPOWER Solar and Wind Power Kits
The SUNGOLDPOWER Solar Panel Kit comes with two 100-watt solar panels, a 20A PWM Solar Charge Controller, MC4 connectors and extension cables, and two sets of Z-brackets. Installing these solar and wind power systems is a breeze. The solar panels require no grid connections and will generate sufficient energy to power a small home or a modest business. The SUNGOLDPOWER Solar Panel Kit is available in several color combinations to complement your home.
25-year service life guarantee
With a 25-year service life guarantee, you can be sure that your new solar panel system will produce power for years to come. While your battery's warranty will cover manufacturing defects, it won't cover the loss of power. If you have a solar panel that produces more than 10 kW/h, you should be able to continue using it for at least that long.
The SUNGOLDPOWER Solar Panel Kit comes with two 100-watt solar panels, a 20-A PWM Solar Charge Controller, MC4 connectors and cables, and two sets of Z-brackets. These components work together to deliver consistent solar power, and are designed to be lightweight and durable. All hardware and connectors are dust and IP67-rated, ensuring that your system will last for decades.
No grid lines
A SUNGOLDPOWER solar and wind panel kit includes two 100-watt solar panels, a 20A PWM solar charge controller, and MC4 connectors, extension cables, and two sets of Z-brackets. These solar panels provide a clean look and allow for optimal solar absorption. These panels also feature no grid lines in the front. Unlike conventional solar panels, this SUNGOLDPOWER kit does not require grid lines, which can cost tens of thousands of dollars per mile.
High-efficiency SunPower cells
The high efficiency of SunPower solar cells is due in large part to the company's unique back-contact technology. Invented by SunPower founder Dick Swanson in the early 1980s, this technology avoids metal gridlines on the front surface of the cell, meaning more light is converted into power. A back-contact architecture also helps improve front surface optimization, resulting in less metal on the front surface and localized contacts and gridlines.
Photons, or tiny particles of light, have different frequencies. These photons are responsible for the visible and invisible light emitted from the sun. When these photons strike a PV cell, they are scattered by the cell's surface, reflecting some and absorbing others. Some of the reflected photons may turn into heat. The remaining photons, however, have the right amount of energy to separate electrons from atomic bonds, converting sunlight into electrical current.
Another difference between high-efficiency and low-efficiency solar panels is the type of cell. SunPower solar panels use prime cells, which are the highest efficiency silicon cells in the market. These solar panels have higher energy conversion levels, are shade-resistant, and can recharge batteries more quickly than standard silicon panels. The panels are made in the same factories that produce the company's residential solar panels. That's one of the reasons why the high-efficiency SunPower cells are so important.
The most efficient solar panels use N-type monocrystalline silicon or heterojunction cells. While most other manufacturers use mono-PERC cells, several large-volume manufacturers are switching to N-type cells. High-efficiency SunPower cells are a major advantage when it comes to solar panels, as they are based on commercial module architecture. And the technology they use is highly advanced. The next generation of solar panels will have high-performance IBC cells.
The latest generation of solar panels features a unique manufacturing process, known as heterojunction, that increases efficiency. These cells are used to build high-density 60 cell panels. Using this technique, REC is able to achieve higher cell density and power output than competitors. These panels also have higher reliability. These high-efficiency SunPower cells are a major factor in generating power for homes and businesses.
While silicon-based solar cells are the most efficient, perovskite-based solar cells are on the verge of surpassing silicon-based cells. They will be cheaper to mass-produce and more efficient than conventional silicon-only cells. And in the meantime, researchers are experimenting with a hybrid solar cell containing silicon and perovskite materials. While it might take awhile before the technology is ready for widespread use, the high-efficiency SunPower cells should give us something to look forward to.
In the meantime, China is breaking the rule of "more efficient = more expensive." With its new, gap-less solar cells, Chinese companies are already surpassing SunPower's 20 percent efficiency. These high-efficiency solar cells cost less per watt than SunPower's. This means that solar energy is more affordable than ever and that U.S. manufacturers may no longer be able to sustain their premium pricing.
