How solar power can work for you:

Solar energy works by gathering and transforming the sun's beams into energy. This is accomplished by the use of solar photovoltaic (PV) panels, which are often mounted on the roof or in other adjacent sites. Through a mechanism known as the photovoltaic effect, these solar PV panels convert the sun's rays into direct current (DC) energy. The DC power is then passed via an inverter, which transforms it to AC power, which is used to power most homes and businesses. This power is also distributed throughout the building via an electric panel. 

What Happens When a Solar Cell Produces Electricity?

A solar cell is made up of two layers of silicon that have been treated to allow energy to flow between them when exposed to sunshine. One layer is charged positively, while the other is charged negatively. Photons penetrate the layers and give up their energy to the silicon atoms in the electron frame. When photons impact the silicon layers, electrons travel via the junction between the positive and negative layers, creating an electric current.

What Size of Solar Panels do You Need?

Well, the size you'll need to install at home is mostly determined by your electricity consumption. A normal home uses roughly 20kWh of electricity each day on average. As a result, you can construct a 5kW solar system to meet your daytime energy requirements. However, because solar systems are quite inexpensive, it is recommended that you install the largest panel you can afford. Feed-in tariff arrangements allow you to profit from the excess energy you create by feeding it back to the grid. Solar panels with capacities of 6.6 KW, 8 KW, and 10 KW are also available, with prices varying proportionally.

How to Choose the Best Solar Company in Perth?

Solar panels are the ideal item to use if you've opted to generate your electricity at home. However, for the best outcomes, the best solar system must be installed. Here are some helpful hints on how to choose solar panels in Perth that can properly meet your electricity needs:

  • Solar panel cost–Of course, the cost of the solar system will have the greatest impact on your decision. Well, it depends on factors such as size, quality, brand, durability, and any certifications, among others.
  • Quality refers to the procedures employed in manufacturing as well as the materials used. Panels are made from a variety of materials, each with its price, quality, and efficiency.
  • Size–When choosing a size, make sure it is large enough to fulfill your daily power needs. Additionally, you must have sufficient space to install it.
  • Durability is important, and most panels come with a warranty of at least 25 years. You can distrust the system (and the brand) if it doesn't come with a longer warranty period.
  • The impact of heat on the panel's operational efficiency is measured by the temperature coefficient. Choose a unit that has a smaller proportion for each degree of Celsius.
  • Solar panels come in a variety of shapes and sizes. Monocrystalline, multi-crystalline (polycrystalline), thin-film, PERC, bifacial, and interdigitated back contact solar cells are among the options.
