Factors Affecting Your Solar Energy Output
Many factors affect the energy output by your solar energy system. Some vary and some are fixed, but knowing what these factors are can help you combat them. There are also things you can do both before and after your system is installed to increase the efficiency of your solar energy system.
The electrical output of solar panels is measured in watts. The amount of wattage produced by solar panels is what differentiates them from each other. There are several scenarios during which solar panels reach their maximum output. High noon is one of the main ones since it is during the hottest part of the day. When it is not raining or snowing and the skies are clear, solar panels are able to produce at maximum efficiency. Other conditions include the sun being perpendicular to Earth, solar panels being optimally tilted and the panels facing southward.
Weather conditions can majorly impact the energy output by your solar energy system. Clouds, rain, snow, fog, haze and smog can all reduce the amount of sunlight that reaches your solar panels. As a result, the power your solar energy system generates is greatly reduced. To combat this, make sure that your system includes a battery bank.
A battery bank can save excess energy produced on clear and sunny days. You will be thankful for this on days when your system is not producing much.
Time of Day
Solar energy is at its peak at high noon. Although your solar energy system will produce power in the morning and late afternoon, the majority of your system’s output will be produced around noontime. Your system will be more efficient during the summer than it will be during the winter when the days are shorter. Once again, however, having a battery bank included in your solar energy system can help to combat this problem.
Proximity to the Equator
Your proximity to the equator affects the power generated by your system. Your solar panels will generate more electricity the closer you are to the equator.
Your solar energy system needs to be installed in an open area unaffected by shade. If even a small section of the solar panels are shaded, the energy output will be reduced. This issue is why it is so popular to place solar panels on roofs. This method works only if you do not have any large trees or other structures that shade your roof.
Even when installed on your roof, solar panels can become dirty. Pollution, traffic dust and even bird droppings contribute to soiling the solar panels. When the panels are dirty, their efficiency is reduced. To combat this, be sure to have the panels cleaned regularly, whether you do it yourself or pay somebody else to do it.
You can help your solar energy system be more efficient by making sure it includes a control flow system. The control flow system reduces the volume of water that needs to be heated, thereby increasing the solar energy system efficiency.
Another way to increase the efficiency of your solar energy system is to install solar roof shingles instead of traditional solar panels. Since solar shingles cover the entire surface of your roof, problems such as the tilt angle can be done away with. You can also save money, as you will not need to install additional components like control flow systems to combat efficiency problems.
