Solar Panel Installation – As the human population increases, it is very likely that a power crisis will arise. Coupled with the increased fuel prices and the use of fossil fuels for conventional power plants, reserves will become scarce in the long term. This electricity crisis must occupy everyone because if it is not expected, this crisis will come faster. Besides being smarter about using electricity, switching to new and renewable energies by installing solar panels can be a solution to saving electricity. Here is what you need to know about solar panel installation guide.
What are solar panels?
Solar panels are devices that can convert solar energy into electrical energy. Photovoltaic technology (photovoltaics / PV) is used to convert solar radiation into electrical energy. This generated electrical energy is stored in a battery that you can use for electronic devices and adapt to your electrical needs.
History of the solar panels
The sun is one of the giant stars in the universe. This sun offers an unlimited variety of energy in it. With the development of technology, solar energy can be used as an alternative source of the electrical energy much needed by mankind.
For historical reasons, this technology already existed in the 18th century, in 1839 to be precise. A physicist from France named Alexandre Edmond Becquerel was the first to shape photovoltaics.
Initially, photovoltaics was initiated by irradiation experiments with two electrodes. Selenium, with which small amounts of electrical energy can be generated, is used for this irradiation. This experiment is proof that electrical energy can be obtained from light energy.
In 1904 Albert Einstein also researched solar cells, the so-called photoelectric effect experiment. It wasn’t until 1941 that a researcher named Russell Ohl succeeded in developing solar panel technology. This technology became known as solar cell technology and is used to this day.
The sun as an alternative energy and saving energy
Energy from solar panels is often used as alternative energy to overcome rising prices for conventional and unsubsidized electricity. The main energy comes from solar energy, which you can obtain free of charge. Geographically, Indonesia lies 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 make optimal use of solar energy as an alternative energy source for electricity for authorities, industry, and households, you can save electricity costs. You can use the money saved from saving electricity for other purposes. The facts on site say that the use of solar panel technology can cut electricity bills by up to 50%.
Types of solar panels
It is very important for you to know the types of solar panels. The goal is that you don’t go wrong in choosing the right solar panel to suit your needs. Below are some of the types you need to know about:
Monocrystalline silicon
It’s one of the most common types of solar panels. This type of solar panel has various advantages such as high efficiency and long service life. The solar cells that make up the panels are made of pure silicon crystals that are machine-cut into thin slices to form a circle. These solar cells are called “monocrystalline” because the silicon used is monocrystalline silicon.
The efficiency of monocrystalline silicon solar modules reaches more than 20%, which is much higher than that of other types of solar modules. This high level of efficiency indicates that this solar panel can convert solar energy into electricity, so only a smaller cross-sectional area is required to produce the same energy as other types of solar panels. Even so, monocrystalline silicon is the most expensive type of solar module with the best quality.
Thin film solar cell
This type of solar panel is called “thin film” because it uses very thin solar cells, around 10nm in size, which are much thinner than the 200-300nm type of crystalline silicon. This thin film is applied to a surface such as glass, Plastic or metal applied.
With a very thin size, this solar panel becomes very light and flexible. In addition, this solar module does not experience a drop in performance at higher temperatures as with other types of solar modules. Unfortunately, the energy conversion efficiency of thin films is still low at around 10%.
Polycrystalline silicon
Is a type of solar panel made of silicon crystal rods that are melted or melted and then poured into a rectangular shape. The advantages lie in the clearer and also denser arrangement. The properties of this solar panel are quite unique in that the solar cell has cracks or fragments. As the name suggests, this type of polycrystalline silicon solar module is made up of many crystalline silicon fragments.
The efficiency of polycrystalline silicon solar modules reaches 17%. Although the efficiency is lower than that of the monocrystalline silicon type, this type of solar module is widely used because of its relatively lower price.
Examples of the use of solar panels
Examples of solar panel uses are easy to find in life. For example, the use of solar panels at home can be used as an alternative source of electrical energy from solar energy to electrify the house. Solar panels can also be used as an energy supplier to power a wide variety of electronic devices such as fans, machines, computers or entire buildings.
With solar panels, you can also charge your devices like cell phones or tablets or cook with an oven and an electric stove. Solar energy can be used for indoor and outdoor lighting. Finally, solar energy is also useful for water heaters that use solar energy.
For public facilities, solar energy makes sense to illuminate streets and public facilities. This allows the state to save costs. For industrial companies or office buildings, solar energy can be used for office or company activities until the afternoon, then PLN electricity can continue to be used at night. This makes the company cheaper its electricity.
Solar Panel Installation
When installing a Solar Power Plant (Solar Power Plant), it is important that you know the tips or installation procedures that are good and correct. An incorrect installation leads to the Solar Power Plant not functioning optimally or not correctly. Here are some things to consider when installing Solar Power Plant.
Things to consider when installing Solar Power Plant:
Selection of the installation location for solar modules
The installation of solar panels should be placed on the roof of the house since the location is exposed to direct sunlight. Care must be taken that the location of the roof is not exposed to shade from trees or surrounding buildings, which could impair the performance of the solar modules.
Installation of solar power plants
In order for Solar Power Plant to be used over a long period of time, be sure to purchase high-quality Solar Power Plant components. You can buy from companies that already have good credibility, offer product warranties, and have professional and reliable services.
In addition to solar panels, you will also need an inverter, roof-mounted solar panel mounts, cables, and electrical protection devices such as circuit breakers. You will also need carpentry tools such as a screwdriver, an electric drill, or an L-wrench.
The solar panels are mounted on the roof with a solar panel holder, which is usually made of aluminum. Next, the solar panels are connected in series. The connector of solar panel is then connected to an inverter where the direct current (DC) generated by the solar panel is converted into electrical alternating current (AC), which can be used for home electricity needs.
The inverter is then connected to the building’s electrical installation via a cable and a circuit-breaker protective device is installed in front of the connection point to the building’s electricity. After all phases of the installation have been completed and it has been ensured that the installation is safe, tests and commissioning are carried out to ensure that the Solar Power Plant system is functioning properly. After all the steps have been properly and safely carried out, the Solar Power Plant system is ready to generate electricity for you to use.
