How do solar panels work?

Solar energy is obtained by turning the sun’s energy into electricity. This electricity can be used for your home or business. The sun releases packets of energy called photons, which can be used in remote places and even in space.

Today solar energy can be used for multiple things like heat for making hot water, heating up building and cooking, generate electricity with solar cells. It also can be used for drying clothes, and by plants for photosynthesis.

Solar Panels rely on light from the sun, not heat. If the climate is extremely hot, solar panels are usually less efficient. They convert sunlight into DC electricity. When photons touch the silicon cell in the solar panel, the electrons are released creating energy.

Solar Panels are made up of interconnected cells that together form a circuit. They come in various sizes, styles and they have different purposes. A single solar module only produces a limited amount of power, and that’s the reason why most installations contain multiple modules.

Photovoltaic System

The typical photovoltaic system includes:

  • Array of photovoltaic modules
  • Inverter
  • Battery pack for storage
  • Interconnection wiring
  • Solar tracking mechanism (optional)

The most common use of solar panels is solar water heating systems. The price of this type of renewable energy in many countries is cheaper than the ordinary fossil fuel electricity.

In Malaysia, the government has several strategies to encourage the use and growth of renewable energy as sunshine is abundant all year round in the country. The demand for solar energy has risen more and more each year as consumers and businesses learn more about the benefits not only for the environment but also to the economy.

According to the Sustainable Energy Development Authority of Malaysia (SEDA) the market for solar energy has growth much more than any other renewable energy technology. Around 95% of the applications were for less than 72kWp, showing the acceptance of this type of energy from the general consumer.

Malaysia is the world’s third-largest producer of PV cells and modules putting the country in a good position to benefit from the growing solar power usage worldwide.
Shopping for solar used to be a long and complicated process, now it is easy and you can request free quotations. There are hundreds of solar companies in Malaysia, so find the one that is right for you.

As you can see there are many reasons why homeowners go solar, with the most common ones being:

  • Improving the environment
  • Cutting energy costs

But they are other benefits as well:

  • Renewable Energy Source: It can be used in all areas of the world and is available every day. Solar energy cannot run out, we will have access to this energy as long as we have the sun.
  • Diverse Applications: With solar power you can produce electricity or heat. So you can produce electricity in areas without access to energy grid.
  • Low Maintenance Cost: Solar energy systems don´t require a lot of maintenance, you just have to keep them clean. But you should only clean the panels a couple of times a year. You can hire cleaning companies or you can do it yourself. The majority of solar panel manufacturers will give you a 20 to 25 years warranty. The only part of the solar system that need to be changed every 5 to 10 years is the inverter. So after the initial cost, you can expect very little spending on maintenance.

No matter what your motivations are for going solar, just remember to do your research and contact at least two solar power companies to get the best deal. Remember solar power is expensive but your investment can return in seven to eight years, plus studies show that houses with solar panel systems have higher property values and sell more quickly.

As people learn and become more educated about the benefits of solar power, the demand for this type of energy will increase. Keep in mind that the sun is a near-infinite source of energy. So, use it to the fullest to save the environment and money at the same time!
