Solar power has gained many supporters since the 1980s, but it is still regarded as relatively new technology. It has developed to the point where anyone can use solar energy to provide power to a home or electronic device. Small solar calculators are a familiar way that the technology can be used, but it is also possible to place panels on the roof of a building. There are a few types of solar panels available on the market, but the most efficient and well known type is the monocrystalline solar panel. This panel is slightly more expensive, but has many features. It uses the same components as other types of solar panel. Buyers can find monocrystalline solar panels at specialist retailers and online from eBay.
How Do Monocrystalline Solar Panels Work?
Solar panels are a passive method of creating electricity to power devices. Many people in Australia have installed solar panels to take advantage of the amount of sun that the country receives. Some of these solar panels are made using monocrystalline silicon in multiple rows of two stacked wafers of doped silicon. Doped wafers have minute amounts of boron and phosphorus added to the silicon. This creates a positive charge in one wafer and a negative charge in the other. This contrasting charge works just like a battery to create an electron field.
When a panel of stacked wafers is exposed to the sun, the sun's photons displace the electrons in the silicon wafers. They float through the wafers until they encounter the electron field, which acts like a highway to send the electrons to the wires in the solar panel, and through the inverter to the house or a electrical device. These solar panels can also be used to charge batteries. In a similar way to a battery, the panels must receive electrical power from the device or the household wiring to create a closed loop so that the electrons continue to flow.
Features of Monocrystalline Solar Panels
Monocrystalline solar panels have a number of features that make them a better choice compared to other styles of solar panels. They are more efficient, harnessing up to 17 per cent of the sun's energy that hits the panels when compared to just 10 per cent for thin film solar panels. Monocrystalline solar panels are also more durable when compared products made from other materials. The panels are usually covered by tempered glass and come in an aluminium frame, which means they are well protected from the elements. Monocrystalline solar panels have been in use longer than thin film versions, so have more research and studies to back up their effectiveness and lifespan.
Components of Monocrystalline Solar Panel Systems
There are multiple components in a monocrystalline solar panel system. Each component has a straightforward, uncomplicated function.
Monocrystalline solar panels harness the sun's energy. These panels are usually rectangles that are around 61 centimetres wide and 91 to 122 centimetres long. However, panels can be made to any size, even as small as the palm of a hand. The panels have multiple rows of silicon wafers lined with metal wires and covered with an anti-reflective coating. Tempered glass is used to protect the wafers. The back of the panel has DC wires that lead to the inverter.
The inverter is placed between the panel and a battery, household current, or electrical device. It changes the low voltage DC current flowing from the panel into AC current that is more compatible with electrical wires.
The junction box is a small plastic device that is fixed to the back of the solar panel. It is where the metal ribbons or wires carrying electrical current from the solar panel meet with the cables that carry electricity to the rest of the solar system. The ribbons interface with the cable prong to transfer power.
A separate solar panel monitoring system can help a great deal when using solar power in the home. The system operates in conjunction with any electric meter placed at the house by the utility company. This monitoring system can tell the owner how much power is being produced, and even where the system sends it.
Mounting equipment is necessary to attach the solar panel to the roof or side of a building. This equipment consists of aluminium or steel brackets, screws, and bolts. Sometimes freestanding panels are mounted on poles sunk into the ground and secured with cement. The mounting equipment should be strong enough to keep the panel in place for several years, or even decades.
The disconnect switch is usually mounted inside the home or near the solar system. There may also be multiple switches placed within easy reach. The disconnect switch shuts off the solar power to the home in case of an emergency. Anyone in the home or working with a solar power system should know how to use the disconnect switch.
Safety Concerns for Monocrystalline Solar Panels
Solar power is a great way to help reduce pollution and improve a household's carbon footprint. However, even monocrystalline solar panels have safety concerns. Solar panels create electricity and a working system has live current running through it. Make sure that the power is switched off before working with a panel. Only use solar panel systems rated for the device or the household current they are connected to. When wiring the system pay careful attention to the direction of the polarity so that power flows through the system properly. Do not place the electrical system near gas or flammable liquids. Do not wear metal or jewellery while working with the system. Always use a charge controller on a battery. Inspect the system and wires regularly for damage or frayed wires. Finally, work in pairs when checking or fixing solar panels on the roof of a building.
How to Buy Monocrystalline Solar Panels on eBay
eBay sellers offer a range of monocrystalline solar panels, as well as the components to complete the system. The products can be found by using eBay's search engine. Simply enter any keyword from the generic to the specific. For instance, you can search for a type of solar panel, such as "folding solar panel kit". Another way to look for low prices on products is to check on the eBay Deals page. This section is filled with products available at even lower prices compared to those in the main area of the site. Look for monocrystalline solar power products at an additional discount with free postage.
Read the item description carefully to understand the type and size of the solar panels. Check whether the panels are part of a system or whether additional components are required to install them.
Monocrystalline solar panels are made with doped silicon wafers. These wafers are stacked in pairs and in multiple rows on each panel. The top of the wafer is lined with metal wires that help move electrons from the wafer into the solar panel wires. This form of passive energy collection has an efficiency of 17 per cent compared to 10 per cent with other types of solar panels. There are several components for a working solar system, from the panel to the disconnect switch. Each of these parts serves a straightforward purpose, and is essential to power a home or small electronic device. Certain safety procedures must be observed when installing or repairing solar panels because they have live current running through the wires. Monocrystalline solar panels can be purchased from sellers on eBay.
