Solar Panels
How to Build a Solar Panel:
1: Creating a Template & Putting Frame Together. 2: Assembling the Solar Cells.
3: Creating Holes for My Connections. 4: Gluing the Solar Cells Down.
5: Soldering Bus Wire. 6: Visiting the Electric Side.
7: Adding Even Pressure on the Plexiglass. 8: Installing the Junction Box.
What materials are used to make Solar Panels:
By far, the most prevalent bulk material for Solar cells is crystalline Silicon (c-Si), also known as "Solar grade Silicon". Bulk Silicon is separated into multiple categories according to crystallinity and crystal size in the resulting ingot, ribbon or wafer.
Solar Panel manufacturing process:
After having produced the Solar cells and placed the electrical contacts between the cells, they are then wired and subsequently arrayed.
Solar Panel lamination:
Sealed into ethylene vinyl acetate, they are put into a frame that is sealed with Silicon glue and covered with a mylar back on the backside and a glass plate on the frontside. This is the lamination process and is an important step in the Solar Panel manufacturing process.
What are the 3 types of Solar Panels:
There are hundreds of companies manufacturing Solar Panels today. Most of the Solar Panel options currently available fit in one of three categories: monocrystalline, polycrystalline (also known as multi-crystalline), or thin-film.
How long do Solar Panels last:
Crystalline Panels are usually guaranteed for 20-25 years, while film Panels are generally guaranteed for only 2-5 years. The regular warranty for photovoltaic Solar Panels lasts 25 years.
Do Solar Panels Need Servicing:
One of the reasons that Solar Panels are such a good investment is that they require very little Maintenance. Most Solar Panel Systems are fine with basic Checks and cleaning 1-2 times a year. The Solar Panels themselves require little to no Maintenance. Finally, the structure is then supported with aluminum Frames and ready is the PV module.
Power output check
Before the ready Panel can be sold it must Sustain a Testing Procedure to ensure its Power output.
Flash Test
Apart from a visual Test of the Panel, the Testing included a flash Test that Measures the open-circuit voltage (VOC), voltage at maximum Power point (VMP),
short-circuit current (ISC), Current at Maximum Power Point (Imp),
Maximum Power (Pm (W)) and the Fill Factor (FF).
The Parameters of the Modules are Measured at Standard Test Conditions (STC).
Standard Testing conditions (STC):
STC Specifies a Temperature of 25°C and an Irradiance of 1000 W/m2 with an air mass 1.5 (AM1.5) Spectrum. These Correspond to the Irradiance and Spectrum of Sunlight incident on a clear day upon a sun-facing 37°-tilted surface with the sun at an angle of 41.81° above the Horizon.
This condition approximately represents Solar noon near the Spring and Autumn equinoxes in the Continental United States with the Surface of the Cell aimed Directly at the sun.
Note: If you want to start independently, first have a clear Document and have Practical experience, get trade Licenses from Local authorities, then you will be successful.
