Welcome to Solar Energy 101! If you are new to solar panels and generators, both the technology and the setting up process can seem challenging. That’s why we have put together this guide on the basics of solar panels and the basics of solar generators.
We will cover the basics as we dive deeper into what you need to know about using solar energy and understanding solar panels and generators.
Solar Panels 101
In this section, we will explore what solar panels are, how they work, and the different types available in the market.
What Are Solar Panels?
Solar panels convert the energy from the sun into electricity. They are composed of solar cells, which are made up of semiconductor materials like silicon. When sunlight hits these cells, electrons are released, creating an electric current that can power electrical devices and appliances.
Solar panels come in a variety of sizes and configurations, from small portable panels that can be used to charge mobile devices to large-scale installations that can power entire buildings or even cities. The most common type of solar panel is the flat-plate panel, which consists of multiple solar cells arranged in a grid-like pattern and encased in a weather-resistant material.
How Do Solar Panels Work?
Solar panels capture and convert the renewable energy present in sunlight into usable electrical power that can be utilized to provide energy for electrical loads. The panels are made up of individual solar cells that consist of layers of silicon, boron (which provides a positive charge), and phosphorous (which provides a positive charge).
The solar panels absorb photons from the sun, thereby producing an electric current through the photovoltaic effect. The resulting energy created by photons striking the solar panels’ surface allows electrons to be dislodged from their atomic orbits and released into the electric field produced by the solar cells, which pulls these free electrons into a directional current.
The metal plates on the sides of each solar cell collect the electrons pushed out by the electric field and transfer them to the connecting wires. At this point, the electrons move in the form of electricity through the metal wires to a solar inverter that supplies energy to your home.
Types of Solar Panels
There are several different types of solar panels, each with its unique characteristics, advantages, and disadvantages. Here are some of the most common types of solar panels:
1. Monocrystalline Solar Panels
Monocrystalline solar panels are made from a single, high-purity silicon crystal, which makes them highly efficient at converting sunlight into electricity. In fact, these cells have an efficiency ranging from 15% to 20%.
Monocrystalline solar panels conduct electricity more efficiently and work better in the shade and high temperatures, allowing them to produce more solar energy compared to other similar-sized panels. They are also durable and long-lasting. Nevertheless, they tend to be more expensive compared to other types of solar panels.
2. Polycrystalline Solar Panels
Polycrystalline solar panels are essentially fragments from several silicon crystals that are heated, melted, and compressed to make a large solar panel. These cells have a non-uniform, gemlike, and multifaceted surface and are typically blue in color. They come with a glass casing usually made from anti-reflective glass, along with a back sheet, which protects them against damage.
Polycrystalline solar panels are less expensive but also less efficient than monocrystalline solar panels, with an efficiency between 12% and 16%. These panels are the most commonly available solar panels internationally, mainly because of a production boom in China over the past couple of years.
3. Thin Film Solar Panels
This type of solar panel is made of a thin layer of photovoltaic material or a combination of materials, such as copper indium gallium selenide, cadmium telluride, or noncrystalline amorphous silicon deposited onto glass or metal. These solar panels are typically bigger and have a uniform, black appearance.
The efficiency of thin film solar panels is the lowest, ranging from 7% to 13%. However, their main benefits are that they are easy to manufacture, low-cost, portable, lightweight, and flexible. Nevertheless, they are less durable than monocrystalline and polycrystalline solar panels and have a shorter lifespan.
Solar Generators 101
In this section, we will explore the basics of solar generators and understand how they work.
What Are Solar Generators?
Solar generators are devices that convert solar energy from the sun’s rays into electrical energy, which can be used to power various electronic devices and appliances. They usually consist of solar panels, a battery, a charge controller, and an inverter. Solar generators typically have multiple outputs for charging several devices simultaneously.
There are different types of solar generators available on the market, ranging from small portable units that can power a single device to larger units that can provide enough power to run an entire home or cabin. The size and capacity of a solar generator depend on the amount of power needed, the length of time it will be used, and the number of devices that will be powered.
How Do Solar Generators Work?
A solar generator functions by generating electricity using sunlight and storing it in a battery for later use. Here’s a more in-depth breakdown of the process.
- The solar panels transform the energy from the sun into direct current (DC) electricity and pass it to the charge controller.
- The charge controller monitors the electricity’s voltage before storing it, making sure the correct amount of current enters the battery.
- The battery stores the solar power for later use.
- The inverter transforms the energy stored in the battery to alternating current (AC) electricity that most devices and appliances use.
Applications of Solar Generators
