With EV charging in Central Kentucky, the notion of mobility is changing for the better.…
If you think that all solar installers work to the same quality standards, you’re setting yourself up for disappointment. Only a few provide reliable post-installation residential solar panel cleaning in Central Kentucky when problems with underperforming solar power systems arise. A modern solar energy system that’s properly designed, installed, and maintained should provide decades of reliable service.
What You Should Know About Solar Panel Production
Steps in Solar Panel Production
Did you know that a solar PV module comprises solar cells, glass, EVA, back sheet, and frame? Today, you can find three types of solar panels on the market: monocrystalline, polycrystalline, and thin-film solar panels.
It’s important to note that several materials are used to manufacture solar panels at the cell structure level. These types include mono silicon, polysilicon, or amorphous silicon (AnSi). Moreover, the manufacturing process of both mono silicon and polysilicon cells is the same.
Step 1: Silica Sand
In most cases, solar panels are made of silica sand, the primary component of natural beach sand. Although silica makes up more than half of the Earth’s crust, converting this raw material into high-grade silicon is both expensive and energy-intensive. It involves heating silica sand with a form of coal called coke in an arc furnace at extremely high temperatures.
Step 2: Ingots
In the form of solid rocks, the silicon is collected and heated at high temperatures to produce ingots shaped like cylinders. Moreover, manufacturers use a steel cylindrical furnace to form the ingot’s desired shape. They ensure the perfect alignment of all atoms during the melting process based on the required structure and orientation.
Furthermore, the element boron is added to the process to allow for the silicon’s positive electrical polarity. A single crystal of silicon produces monocrystalline cells. Since mono silicon is more efficient at converting solar energy into electricity, monocrystalline panels are more expensive than other alternatives.
Alternatively, polysilicon cells are produced by melting multiple silicon crystals together. After heat application, these crystals have a shattered glass look. Furthermore, cooled ingots are left with flat sides after being ground and polished.
Step 3: Silicon Wafers
Silicon ingots are sliced into ultra-thin disks called wafers. To ensure precision cutting, wafer manufacturers use a wire saw. Each wafer should be as thin as a piece of paper.
Since pure silicon has a shiny appearance, it reflects the sunlight. Applying an anti-reflective coating on the wafer’s surface facilitates sunlight absorption and reduces the amount of solar energy lost.
Step 4: Solar Cells
A wafer is a thin slice of semiconductor or crystalline silicon that works as a substrate for solar cells that convert sunlight into electricity. The metal conductors placed on the surface of each treated wafer create a grid-like matrix that ensures solar energy conversion efficiency.
Moreover, phosphorus is diffused in a thin layer over the wafers’ surface to charge it with a negative electrical orientation. The combination of boron and phosphorus creates a positive-negative junction that’s crucial for ensuring effective solar cell production.
Step 5: Solar Panels
Metal connectors link soldered solar cells together in a matrix-like structure to make up solar panels. Once the cells are integrated, a thin glass coating is placed on the side of the panels that face the sun.
Furthermore, a PV back sheet made of a polymer or a combination of polymers is placed at the bottom of each panel. Besides acting as an insulator, the back sheet protects the solar cells and electrical components from external stresses.
Next, the PV junction box is installed directly on to the back of each panel to serve as the interface between the panel’s conductor ribbons and the DC input and output cables. The frames are attached to the panel’s PV laminates to protect them against impact and weather. Finally, a thermoplastic polymer called EVA (ethylene-vinyl acetate) forms an insulating and sealing film around the solar cells.
Step 7: Testing
The newly manufactured solar panels are tested to ensure they meet the expected performance. In most cases, manufacturers use STC (Standard Test Conditions) as a reference point during the testing process. Solar panels that make the cut are cleaned and inspected before they’re shipped.
How to Get the Most Out of Your Solar Power System
Monitor the Health of Your System
Unless you monitor your system’s performance, you won’t know if your entire solar power system is performing at its peak. For this reason, it’s best to ask your solar power company about remote monitoring thru a customer portal on the manufacturer’s website or through smartphone apps. If you leave the monitoring to the company, they’ll contact you to discuss your options as soon as they spot a problem.
Your solar panels will produce more energy if they get more sunlight. If trees and shrubs grow around your home, keep them trimmed so that they won’t stand in the way between your solar panels and the sun.
You’ll also want to consider the sun’s path from dawn until dusk. Additionally, follow the shadows as they move throughout the day so that your panels can get maximum sun exposure.
Keep Your Solar Panels Clean
Dust, dirt, bird droppings, insects, pollen, fallen leaves, organic growth, and thick layers of snow and ice can wreak havoc on your solar panel efficiency. Whether you’ve had solar panels on your roof for years or you’re looking to install a solar power system soon, you’ll want to ensure regular solar panel cleaning to get the most out of your investment.
Pick the Right Solar Partner
Purchasing a solar power system is a long-term investment. For this reason, it’s best to select the right solar installer with the skills and experience to custom-engineer an optimized system that works for you. Also, you’ll want to check if they have the resources to service your system over its lifespan.
