How Solar Energy is Converted to Electricity?admin / No Comments
The initial step to convert solar energy to electricity is to install Photovoltaic (PV) cells or solar cells. Photovoltaic means light and electricity. These cells arrest the sun’s energy and convert it into electricity. These solar cells are made of materials that show photovoltaic effect, meaning when the sun rays strike the Photovoltaic cell, the photons of light spook the electrons inside the cell triggering them to start flowing, ultimately producing electricity.
When looking to buy solar panels, it would be beneficial to know the options available in the marketplace. Here is an outline of the main ones:
Polycrystalline – This utilizes Multicrystalline Silicon
Monocrystalline – This is ideal for small spaces
Thin Film – Typically bigger in size and a lot more efficient during the day
The disparity between the material used to manufacture monocrystalline and polycrystalline lies in the constitution of the silicon substrate utilized to manufacture solar cells and ultimately, solar panels. As the name suggests, polycrystalline implies numerous crystals, while monocrystalline implies a single crystal. The larger the crystal sizes, the more efficient the solar cells, which explains the reason monocrystalline cells are normally 10 – 15% more efficient than the polycrystalline crystals.
How Solar Panels Work?
The solar panel should be mounted on an open area that is not obstructed by trees or any installation. A roof is normally the best bet. It’s then wired into the building through the inverter. The inverter is a device that converts AC (alternating current) to DC (direct current). So, in this case, the alternating current is the energy created by the solar panels. This solar energy is converted into AC. The reason for converting the direct current into alternating current is to enable the energy to be used by various home appliances just the way you power your electronics with normal electricity.
Considerations to Keep in Mind Before Installing Solar Panels
Before taking any step to install solar panel in your home, make sure the solar power befits you and your home. Then, ensure that sufficient sunlight is available in your locality. The suitability of solar energy varies considerably with how much sun an area receives. If your area does not receive sufficient sunlight, investing in solar panels will not be the best cause of action.
After determining that your area receives adequate sunlight, make sure installation space is available. We’ve learned that solar panels are quintessentially set on roofs of buildings. While this is laudable, it’s not the only option. If you have an open space to spare in your backyard, it would be an ideal spot for ground mounts. The backyard option is ideal for those whose roofs are heavy shaded or not structurally essential for solar panels. Also, it is paramount to know the local laws regarding solar panel installation to avoid getting into trouble with the local authorities.
