Solar energy is one of the most renewable sources of energy that we have on earth. Solar energy starts with the sunlight. Solar panels (“PV panels” or more commonly known as “solar cells”) are used to transform the sunlight into solar energy which is made into electricity that can be employed to power electric loads. It is possible to capture and store the solar energy for future use in order to make electrical appliances or heat our homes. Solar energy products are a very popular way to contribute to the preservation of our environment.
There are three types of Solar Panels: Photovoltaic cells (“PV”), which use photovoltaic technology to create electricity; Active Solar modules (“AS Module”), which use the combined energy of a battery and an inverter to store energy for use when it is not cloudy or night time; and Differential type Solar modules (“DTS”). Both PV and DTS Solar Panels are mounting on Solar Panel’s frame which consist of many individual PV cells (“solars”), which are wired together to create an array. This array of solar cells creates an electrical current when sunlight hits the cells. This current is then routed through wires which are connected to an inverter which converts this current into usable electricity. The electricity generated from Solar Panels can be stored by the inverter and then used when necessary, or can be sold back to the utility companies, depending on the provider’s Renewable Energy Agreement.
Solar energy products are usually manufactured using what is known as crystalline Solar module. Crystalline Solar modules, as the name suggests, are made from crystalline silicon, which is a semiconductor. This type of Solar module has proven to be effective and reliable and is often used in applications where other Solar Panels is unsuitable, such as long-term use, or applications which need very high power conversion efficiencies. The efficiency of crystalline Solar modules means that they produce electricity at a much higher efficiency than most other Solar Panels. Another advantage of using crystalline Solar modules is that they do not suffer degradation of their electrical charge even when exposed to extreme weather conditions. This is because, unlike many other Solar Panels, their crystalline structure does not suffer damage easily, and its crystalline structure is immune to damage caused by heat, cold, chemicals and oxidants.
Solar energy panels are made from different materials to achieve specific results. Solar Panels can be made from silicon crystals, P-type silicon crystals, or a combination of both. Solar energy modules made from crystalline silicon have proven to be the most efficient, and therefore relatively cost-effective Solar Panels. In terms of cost per kilowatt hour (CWh), crystalline Solar Panels are still significantly more efficient than other Solar Panels, but considerably less efficient than wind or solar power generators. As the efficiency of crystalline Solar modules increases with increasing temperature, the cost per CWh decreases.
When a Solar Panel is working at its maximum output capacity, it is called “activation energy”. Solar activation energy is basically the amount of electricity produced during hours when the Solar Panel is not in use and is equal to the total sum of watts divided by the total time the Solar Panel is switched-on. Activation energy is the largest factor in determining the efficiency of any Solar Panel. As activation energy increases with increasing temperature, the cost per CWh decreases. This means that Solar Panels can become even more cost-efficient over time.
Solar energy panels play an important role in our environment. Although Solar energy panels may initially cost more to build and install, the long-term savings from using Solar energy are large. Solar energy panels may not be as easy as breaking open a tab of cells, but their steady record of producing electricity without polluting the environment makes them a worthwhile investment for homeowners looking to reduce energy costs.
