How Solar Panels Work

The solar panels absorb sunlight during daylight hours and convert the energy from light into solar electricity to power our homes. Solar power can then be used to provide electricity for all of your electrical needs!

Solar panels are made up of individual solar cells that use layers of silicon, phosphorous (which provides the negative charge), and boron (which provides the positive charge) to generate electricity. Photons from the sun strike the surface of a solar panel that initiates an electric current by knocking out electrons loose trapped in atomic orbits into an electric field generated by the solar cells that attracts them with force and pulls these free electrons into a directional flow. This whole process is called the Photovoltaic Effect.

The solar panel is a combination of 3 materials-silicone, solar cells, and glass.

Solar panels are made up of either 72 or 60 solar silicon cells. They’re electrically interconnected in series and parallel, sandwiched between glass and plastic, framed with metal brackets before being installed on the roof for a clean energy future. A typical mono-crystalline cell produces around 250 to 300 Watts at an open voltage of 38 Volts DC.

Solar cells are a vital ingredient in solar panels. They’re made by slicing crystalline silicon into wafers, then cutting, shaping, and polishing them to create the final product. Photons passing through these modules can be converted into electricity with no pollution or noise generated from traditional power plants!

Note: Silicon (Si) constitutes almost 30% of the earth’s crust and is the 7th most abundant element in the universe.

Here are the steps that describe how solar panels produce electricity:-

1. Solar panels absorb sunlight and become active.

2. The solar cells on solar panels produce electricity (Direct Current).

3. DC electricity is not the type of power that most homes use. Solar inverters convert direct current into Alternating Current (AC) electricity.

4. Then the alternating current is distributed to your home through your electrical panel.

Do the calculation:-Calculate how much electricity you use and at what times you use it to size your solar panel system. Homeowners typically use 20 kWh of energy a day. An average home such as this would need a system of 5kW to meet its daytime additional energy needs. 

Warranties:-Solar panels typically have a product warranty of 10 years, but they can be as long as 25 years. Most solar panel performance warranties last for 25 years, making them perfect products if you’re looking for an investment that will last. An inverter’s warranty generally ranges from 5 to 10 years, while solar batteries come with a typical 10-year warranty. Choosing a product with an Australian presence or locally sourced suppliers can simplify the warranty process.

Cost:- A large population often buys based on price, but you should not view price as the deciding factor. Value for money goes beyond price. This means:

• The lifespan of the system

• The size of the system

• How much electricity it will produce in the long run?

• What will be the savings on the electricity bill?

Here is the approximate price of the solar panels:-

Size of the Solar Panel System: 3KW, 5KW, 6.6 KW, 10KW

Average price (approx): $4,193 $5,488 $6,584 $9,975

You can expect to spend approximately between $6,000 and $8,500 for a quality 6.6kW system. We recommend buying a higher efficiency panel and an inverter that will hold their performance for a longer period and produce solar power for the best performance.

The cost of power is increasing in Australia, leaving solar installations on the rise. With the cost of panels dropping, installing them with your home’s electrical system will save you money in the long run. The price of solar panels in Australia is at its lowest point ever. Good solar panels are now so cheap that you can get a return on your investment in 3-5 years.
