Benefits of Solar Panel
Long-Term Stability
The energy industry is plagued by fluctuations in prices as supply and demand continually change. In general, however, electricity prices are on the rise. With solar panels, however, you can mitigate the risk of rising electricity costs, even if prices skyrocket.
Increase Real Estate Value
Installing solar panels on your facility raises your real estate value. At the same time, if you ever choose to sell your building, you can attract a new set of prospective buyers looking for energy-efficient technology. A comparative case study concluded that homes with solar panels typically sell 20% faster and for 17% more.
Start Saving Right Away
With a solar power purchase agreement (PPA), you can essentially lease your solar system for little to no money down, allowing you to start saving on electricity bills right away. Your solar partner takes care of installation, maintenance, and repairs. That way, you can get the latest in energy-efficient technology with minimal hassle. At the end of the lease, you then have the option to buy your system.
Quick ROI
If you choose to pay for your solar system outright, you can experience a full return on your investment in as little as 10 years.
Leverage Incentives
Solar solutions open up many possibilities for tax breaks, rebate programs, and other incentives to help cover the costs of your solar panel installation. By leveraging these savings programs, you may potentially be able to cover up to half of your upgrade expenses. Solar renewable energy credits (SRECs) can even help you generate positive cash flow over time.
Get Guaranteed Reliability
Most reputable solar energy companies offer a 20- to 25-year warranty with their solar panels. The standard in the solar industry is a performance warranty that guarantees 80% performance after 25 years of operation. But with proper maintenance, solar panels generally last much longer than this. In many cases, you can expect solar panels to generate optimal levels of electricity for anywhere from 30 to 40 years.
Protect the Environment
While solar panel solutions offer a number of financial benefits, you shouldn’t overlook the environmental advantages of going solar. Solar electric power can help you lower your carbon footprint substantially by freeing you from your dependence on fossil fuels. For residential solar systems, you can offset up to 100,000 pounds of carbon dioxide in 20 years, which is equal to driving a car for approximately 100,000 miles. These figures can be even higher for industrial applications.
Material of Solar Panel
Silicon Solar Cells
Silicon solar cells convert the Sun's light into electricity using the photovoltaic effect. Soldered together in a matrix-like structure between the glass panels, silicon cells interact with the thin glass wafer sheet and create an electric charge.
01
Metal Frame (Typically Aluminum)
A solar panel's metal frame is useful for many reasons; protecting against inclement weather conditions or otherwise dangerous scenarios and helping mount the solar panel at the desired angle.
02
Glass Sheet
The glass casing sheet is usually 6-7 millimeters thick, and although it is thin, it plays a significant role in protecting the silicon solar cells inside.
03
Standard 12v Wire
A 12V wire helps regulate the amount of energy being transferred into your inverter, aiding with the sustainability and efficiency of the solar module.
04
Bus Wire
Bus wires are used to connect the silicon solar cells in parallel. Bus wires are covered in a thin layer for easy soldering and are thick enough to carry electrical currents.
05
Solar Panel Manufacturing Process
Building The Solar Cells
The primary components of a solar panel are its solar cells. P-type or n-type solar cells mix crystalline silicon, gallium, or boron to create silicon ingot. When phosphorus is added to the mix, the cells can conduct electricity. The silicon ingot is then cut into thin sheets and coated with an anti-reflective layer. Then, narrow slits are cut in the cells to funnel the flow of electricity.
Solder Solar Cells Together To Create A Panel
After the phosphorus gives the silicon wafers their electrical charge, metal connectors link each solar cell in a process called soldering. The number of cells soldered together depends on how big the solar panel is manufactured. For reference, 60 cell-panels are standard size, and 72-cell panels are generally used for commercial projects.
Install A Back Sheet, Front Glass Layer, And Frame
A back sheet is installed to the bottom of the solar cells for protection, usually made from an ultra-durable plastic material. Next, a thin glass sheet is installed on top of the solar cells to filter the sunshine into the solar cells. These parts are held together by ethylene vinyl acetate (EVA) glue. All these components are confined by a metal frame that latches onto mounting clamps on your roof.
Install The Junction Box
The junction box protects a solar panel's wiring from damage to keep the flow of electricity moving from the panel to its inverter, preventing electricity from reversing direction. This functionality is essential when a solar panel isn't producing electricity because that panel will try to consume energy instead. The junction box doesn't allow any reversal of electric flow, so your solar panels can function correctly.
Quality Testing
Each solar panel to hit the market is tested under Standard Test Conditions (STC) to ensure that the panels meet their projected outputs, efficiencies, and everything else the manufacturer promises in their technical specification sheet. Panels are put into a flash tester where "standard” conditions are simulated: 1000W/m2 irradiance, 25°C cell temperature, and an air mass of 1.5g. If it passes, the solar panel is ready for shipment and installation.
