Solar energy comes from a sun. Solar panels are used to change sunlight (composed of energy particles referred as “photons”) into electrical energy which can be utilized to run electrical charges.
They can be utilizing for a variety of purposes, including remote cabin power systems, broadcasting, remote sensors, and can also be used for commercial and residential solar systems to generate electricity.
History of solar panels:
The history of establishment of solar system goes back hundred years. In the past, it was mainly used to generate steam, which was later used for starting the machinery. However, it was not until Edmund Becquerel discovered the “photoelectric effect” that he made it possible to convert sunlight into solar power.
Becquerel’s discovery led Charles Frits to invent the first real solar cell in 1893, which was made by coating of gold on a selenium foil. There was a device from the beginning, which we call solar cells today. Russell Ole, an American innovator at Bell Labs, obtained the world’s first patent for silicon solar cells in 1941. In 1954 the first module of solar panel was invented by Ohl’s with the same company.
Nowadays, solar energy and complete solar collectors are used to power various appliances. Yes, solar cells are still used in pocket calculators as solar panels. But they provide solar energy for entire residential and commercial area (such as the Google California’s headquarters).
How solar panels works:
Solar panels store energy from sunlight and change that energy into electrical energy, which can be used to generate electricity. Solar modules are composed of multiple solar cells, which are created by layers of silicon and phosphorous (providing negative charges), and boron (providing positive charges).
The solar panel absorbs photons, which initiates electricity. The ending energy is generated by photons hitting the base of the solar panel, which allows electrons to escape their atomic trajectories and converted into the electric energy with the help of solar cell. It then converts free electrons into a drawn directional current. All this procedure is called the photoelectric effect.
The solar panels can generate enough solar energy to meet all your energy needs. The excess electricity generated is sent to the main grid to facilitate the electricity used at night. In a balanced grid-connected configuration, solar panels generate energy during the day and are used in the house at night.
The clean metering program allows solar generator owners to charge a fee when their system generates more energy than their household needs. For off-grid solar applications, the required components are battery packs, charge controllers, and in most cases, inverters. The solar panel sends direct current (DC) to the battery through the charge controller. Then the electricity comes from the battery. An inverter can change direct current into alternating current (AC) which is used in non-DC equipment.
Using inverters, solar panels can be expanded to meet the most demanding electrical load requirements. Alternating current can be used to power residential or commercial buildings, caravans and ships, remote cabins, passenger cabins, or loads in houses to remotely control traffic. , Telecommunications equipment, gas and oil flow monitoring, SCADA, RTU, etc.
Benefits of solar panels:
For many applications, the use of solar panels is a very practical way to generate electricity. Off-grid refers to living in a place where there is no power supply from the main grid. Remote houses and huts benefit greatly from solar energy. You no longer need to spend a lot of money to install masts and cables from the nearest access point to the main network.
Solar power systems may be cheaper and, if properly maintained, can provide more than 30 years of electricity. In addition to the fact that solar panels can keep you away from the grid, perhaps the biggest benefit of using solar energy is that it is a clean, renewable energy source. It is becoming more important to make every effort to reduce atmospheric pressure through greenhouse gas emissions.
Solar panels have no moving parts and require minimal maintenance. If properly maintained, they can be durable for decades. Last but not least, the advantages of solar collectors and solar power generation: After the initial installation cost of the system is amortized, the system will produce electricity during the remaining service life, depending on the circumstances, up to 15-20 years. System quality is absolutely free! Additional income from the power company’s.
If you use less energy than the solar power system generates, you can sell the excess energy to your power company, sometimes with a surcharge. There are many other uses and benefits of using solar panels to generate electricity, which are not listed here. But browsing our website will give you a good understanding of the versatility and convenience of solar energy.
Steps for installing solar panels:
- Installing scaffolding first, you need to install scaffolding on the roof to ensure safety during the entire installation process.
- Install the solar panel platform the next step is to configure the solar panels installation system that is used to support the bases of the solar panel. The entire installation frame should be tilted eighteen to thirty-six degrees to maximize exposure to sunlight.
- Installing the solar module when installing the bracket, first solar panels must be fitted in mounts. Be sure to tighten all bolts and nuts to ensure stability.
- Connect the solar panel. After installing procedure, next step is to connect the solar panels with electrical wiring. To connect with the electrical wiring, connectors are used because without them, the installation is not complete. Connectors are mainly used in installation to shut down the supply of current in the area of installation.
