Solar Power Systems to Generate Electricity
Solar Power is the most reliable energy source that can be used to power up your home and business needs with a solar system. It is the cleanest energy source that is having the disinfecting properties. Nowadays as an alternative to the traditional power generation systems, solar power is used to generate electricity. Solar panels (Photovoltaic panels) are used to create electricity from sunlight (solar energy).
To understand the power generation from solar energy let us see the components and processes in detail.
Solar panels or photovoltaic panels consists of many photovoltaic cells. (”Photovoltaic” means “electricity from light” photo = light, and voltaic = electricity). When the “particles of light” (photons) hit on these photovoltaic cells on the solar panels, electrons are emitting and generating a flow of electricity. Photovoltaic cells are usually made up of any semiconducting materials like silicon. Photovoltaic cells need a magnetic field or an electric field to generate electrons. To create this, silicon is combining with other materials and makes a positive or negative charge on opposite poles. Electric fields are generated when opposite charges are separated. When photons hit on photovoltaic cells, this process is happening and thus generating a flow of electrons called electricity.
Solar Power Systems – where to install the Solar panels
Solar panels should place in a proper place where it is possible to get enough sunlight. In the most type of the Solar systems, Solar panels are placing on the roof of a building or house. It is because there won’t be any shade and hence will get enough sunlight to produce the power. During daytime between 9 am to 3 pm is the most sunlight getting hours. A south facing installation will provide you enough energy between these prime hours on a sunny day. Some other factors may affect this power production. Rainy days or shades of trees etc. can affect the power generation. Even one cell among the 36 cells in a solar panel is shaded; it will affect the power production very much. To avoid this situation, many solar companies are using a device called ‘solar pathfinder ‘ to carefully identify the shading in a potential area before installation. It is important to install the solar panels in the correct place where it can get the maximum sunlight throughout the year. The angle of sunlight can detect with pivoting panels that can track the sun in the sky.
Solar Power Systems consists of a number of solar panels based on the power requirement. The electron flow or electricity generated by the hitting of photons on photovoltaic cells can be collected and channeled together. This is done by wiring the individual solar panels in a series together, to form a solar photovoltaic array. Strings from these photovoltaic arrays are combined in an electrical box called “fused array combiner”. The connections from here deliver power to an inverter. Direct Current (DC) will be producing at this stage and it should be converted to AC (Alternative Current) to be useful for home and business needs.
Inverter in a Solar Power System
The inverter in a Solar Power System converts the DC into 120 Volt AC. This electricity can be used by connecting inverter directly into a “dedicated circuit breaker in the electrical panel”. Place the inverter in an easily accessible location and near to the electrical mains if possible. Inverters may make a slight noise and hence this should be taken into consideration while placing it in a location.
Net meter – Solar Power System
In a solar power electric system, the DC produced from the solar arrays is converted into AC power and served directly into the “utility power distribution system” of the building or house. This power generated is “net metered”, when the solar arrays are generating electricity. When the utility power goes offline, the grid-tied systems will automatically shut off and thus protect workers from power being back served into the grid. These types of “solar-powered electric systems” are known as “on grid”. Means they are “battery-less”. Most of the Solar Power Systems are being installed like this today.
