High Efficiency Rigid Solar Panel With SunPower Cells In 2023
Rigid solar panels can typically last up to 25 years and can be used on roofs, caravans, boats, farms etc.
Solar cells differ due to their conversion efficiency and cost.The most common are monocrystalline and polycrystalline cells. And Today’s article introduces you to sunpower solar cells.
How do solar panels work?
When sunlight hits a solar panel, the energy from the sun is absorbed by the photovoltaic cells in the panel. This energy creates electrical charges which move in response to the internal electric field in the cell, resulting in the flow of current.
If electrodes are led on either side of the internal electric field and a load is connected, then the load will have “current” flowing through it, resulting in power output. In this way, the sun’s light energy is turned directly into usable electricity.
So how long can a rigid solar panel supply you with electricity? Does the output power fade?
How long do solar panels last?
Rigid solar panelshave a service life of up to 25 years. Rigid solar panels are more robust and durable than other types of solar panels, such as flexible solar panels and portable solar panels.
However, all solar panels are subject to power degradation.Over time, the power output decreases – by approximately 0.8% per year. So you can expect your panel to produce 99.2% of its original output in the second year, 98.4% in the third year, and so on.
In addition, you can also look at the warranty period of your solar panels. The longer the warranty period, the longer the life expectancy.
If you want to install a rigid solar panel on the roof of your house, on the roof of your caravan or on your yacht, here you can find a solar panel from SUNGOLD.
Introduction to high efficiency rigid solar panels
SUNGOLD’s SGSP series solar panels are made from sunpower cells and have a conversion efficiency of over 24%. The solar panel also has an IP67 waterproof rating for outdoor environments. It also features anti-reflective, high transparency tempered glass for enhanced stiffness and impact resistance.
The SGSP series solar panels are guaranteed for 10 years and have a 25-year lifespan. You can save money on your home’s energy bills by installing solar panels on your roof to take advantage of solar energy.
An important point is that SunPower cells are made using the classic IBC cell process. There are no grid lines on the front side of the cell to avoid shading losses from the metal electrodes. The cell absorbs the maximum amount of sunlight and increases conversion efficiency.
What is an IBC cell?
The most distinctive feature of IBC solar cells is that the PN junction and metal contact are located on the back of the solar cell, completely avoiding the shading of the metal grid electrodes on the front side.
This cell structure maximises the use of incident light, reduces optical losses and has a higher short-circuit current. At the same time, the optimized metal grid electrodes on the back reduce the series resistance.
This type of solar cell with no shading in front not only has high conversion efficiency, but also has advantages such as aesthetic appearance, which makes it suitable for application in BIPV and has great commercialisation prospects.
The IBC cell is currently the most complex process and the most difficult structural design among commercial crystalline silicon cells, marking the highest level of crystalline silicon R&D and manufacturing.
Bottom line
Photovoltaic modules using IBC cells have the advantage of minimising wastage of light-receiving area and facilitating welding between cells, which is conducive to cost reduction and wider application.
