Just How Much Electric Power Can A Solar Panel Generate? How Many Panels Do You Need?
Find out how to calculate solar production and your true energy needs. The photovoltaic panels in the Polysilicon Solar Market that convert sunlight to electricity are essential in producing solar power. The size and material of the solar panel, with its orientation to the sun and the amount of sunlight, determines its capacity to produce power.
Simply How Much Power Does A Solar Panel Generate?
The solar panel is tested under Standard Test Conditions (STC) that is equivalent to full sun at sea level of 25 degrees Celsius, after manufacturing. After which the panel is rated for the number of watts produced under the test conditions. For instance, a normal solar panel meant for a home system might produce up-to 200 Watts. If five such panels are combined the will produce 1000 Watt or one Kilowatt. This implies if the sunshine on the one KW array for an hour, it will translate into one kWh of electricity. If the array is exposed to the sun for six hours, then it can produce six kWh. This is the amount of energy that will be available for you are to operate your electrical appliances.
The magnitude of sunlight expected throughout the entire year will determine the number of KWh you can expect from the solar array. However, days may vary in length with the seasons. On cloudy days, the panels will only produce about 20 - 60% of their full rating based on the cloud thickness. Climate data is used to determine the average solar radiation per day throughout the year when calculating. This involves multiplying the solar radiation by the panel rating to determine the expected energy output.
How Much Electricity Do You Use?
The amount of electricity required will determine the number of solar panels that you need. Electricity is also measured in kWh. If you are connected to an electrical utility provider, it will be easy to get this information on the utility bill. Evaluate the KWh delivered between actual readings to determine your monthly usage.
You will need to calculate the power you need if you decide to use a standalone (off-grid) solar power system. First, multiply the power (in kWh) that one appliance uses by the number of hours per day that it is in use. This will provide the estimate for the kWh required by that appliance for one day. Repeat this for every appliance using electricity in your home. This calculation is referred to as a load analysis.
Do You Need To Use All That Power?
Solar power installation is usually expensive. Therefore it is important to use less energy and buy fewer panels. There are things that you normally do not need that should be shut down.
How Can I Get More Value For My Solar Energy Dollar?
Despite the Polysilicon Solar Market system ability to offset all of the energy that you use, it will be less costly to save energy first. This will involve using energy efficient lighting and appliances or Shutting off the lights, computer, or TV when you are not using them.
