Solar panels can be an alternative to independent electricity generators. The use of solar panels is also much more economical and promising. Electricity affairs are a top priority that must be budgeted for in family expenses. The reason is because almost all daily activities and use of these electronic devices depend on electricity.
No matter how sophisticated the current technology is, it cannot be operated without electricity. Therefore, electricity is a major requirement that must exist. Unfortunately, the cost or electricity tariff continues to increase. This makes people think about saving electricity use so that the costs incurred do not swell.
Electricity Basic Tariff Issue
Every year the basic electricity tariff will increase due to electricity consumption which continues to increase. Based on the Decree of the Minister of Energy and Mineral Resources Number 143K/20/MEM/2019 concerning the National Electricity General Plan for 2019 to 2038, ESDM projects that the average growth in national electricity demand will reach 6.9 percent per year.
As the human population increases, an electricity crisis is very likely to occur. Coupled with the increase in fuel prices and the use of fossil fuels for conventional power plants in the long term, the reserves are also dwindling. This electricity crisis must be the concern of all people because if it is not anticipated this crisis will occur more quickly. Apart from being wiser in electricity usage day by day, using solar fan may would help it, a little bit. switching to using new and renewable energy by installing solar panels can be a solution for saving electricity.
What Is a Solar Panel?
Solar panels are devices that can convert sunlight energy into electrical energy. Photovoltaic technology (photovoltaic / PV) is a technology used to convert solar radiation into electrical energy. This generated electrical energy will be stored in the battery, which you can use for electronic devices and adjust it according to their electricity needs.
History of Solar Panels
The sun is one of the giant stars in the universe. This sun provides a variety of unlimited energy in it. With the development of technology, solar energy can be used as an alternative source of electrical energy that is much needed by mankind, which means that the sun produces electrical energy using solar panel technology.
Based on history, solar panel technology existed in the 18th century, in 1839 to be precise. A French physicist named Alexandre Edmond Becquerel first sparked photovoltaic technology.
Initially, photovoltaic technology was initiated through irradiation experiments with two electrodes. This irradiation uses selenium which can be used to produce small amounts of electrical energy. This experiment is proof that electrical energy can be generated from light energy.
In 1904, Albert Einstein also did research on solar cells called the photoelectric effect experiment. It was only in 1941, a researcher named Russell Ohl was able to develop solar panel technology. This technology became known as solar cell technology and its use is still used today.
The Sun As Alternative Energy and Energy Saving
Energy from solar panels is often used as an alternative energy to overcome the increase in conventional and non-subsidized electricity prices. The main energy comes from solar energy which you can get for free. Geographically, Indonesia is located on the equator, so Indonesia is very rich in solar energy sources with an average solar radiation intensity of around 4.8 kWh/m2 per day throughout Indonesia.
If you maximize the use of solar energy as an alternative energy source for electricity for agencies, industry and households, you can save on electricity bills. You can allocate the funds you save from saving electricity for other purposes. Facts on the ground say that electricity bills can be reduced by up to 50% by using solar panel technology.
Differences and How Solar Panels Work
The difference between solar panels and solar cells
What is the difference between solar panels and solar cells?
The solar cell is the core of the solar power panel. These cells are arranged in parallel and connected in series and parallel which then form a single solar panel unit. It can be said that solar panels are a combination of many solar cells. The number of solar cells arranged in a solar panel varies from 32 to 96 cells, but in general what is used is a type of solar panel with 72 cells.
How Solar Panels Work
The working principle of solar panels is as follows:
- Solar panels convert energy from the eyes electric day
- The inverter changes the electricity generated by solar panels from direct current (DC) to alternating current (AC)
- Energy is used to power your electrical equipment
Benefits of Solar Panels
The expansion in regular power or PLN power is very large, especially for non-subsidized electricity. The rate of increase can reach 9.7% per year. The cause itself can be caused by various factors. However, the most important role in the increase in electricity rates is the price of fuel. This has an indirect impact on the level of the economy and also the level of social welfare.
Indeed, electricity bills do not increase every year. However, once an increase occurs, the percentage increase can be as high as 30%. In terms of its use, the benefits and functions of solar panels are very environmentally friendly when used because they do not use conventional fuels. The main energy comes from the sun and can be obtained for free.
The most pronounced benefit from panels and solar energy is being able to save expenses. In addition, solar energy can contribute to reducing global warming. You also avoid dependence on conventional electricity. The benefit of installing solar panels is that these solar panels do not require a large area and the installation is very easy.
