The general rule is that countries in the northern hemisphere should place their solar panels facing true south and in the southern hemisphere true north. This is because the earth rotates on its axis at a slight tilt. This is called the ‘projection effect’ is the main reason why the polar regions are much colder than equatorial regions on Earth On an annual average the poles receive less insolation than does the equator, because at the poles the Earth’s surface are angled away from the Sun.
Note that it is True south and True North and not magnetic North or South. Not to go to much technically into it but the Magnetic North or South are influenced by other forces in the earth’s crust that bends the direction. If you are really bent on finding out what would be the best placement for solar panels in your house then it is highly recommended that you take the services of a professional solar installer while carrying out the observation and the analysis yourself.
Other Factors Determining Solar panel Positioning
There are a number of other factors determining the orientation and positioning of solar panels and these include the direction that the property or the roof is facing, the tilt or the angle of the roof, the strength of the roof and the weather type like hail, snow and raining hitting the area all round the year.
Obstructions that might cause shading are also one of the most important factors determining the orientation and positioning of solar panels. The reasons why rooftops seem to be popular when it comes to positioning solar panels is due to the fact they are most likely to receive a significant amount of sunlight needed for the production of solar energy.
To maximize the energy production of your solar panel system, your solar system needs to be installed where the panels remain exposed to a good amount of sunlight. This is the reason why rooftop solar installations in homes is very popular. However, if your roof is not suited for solar panel installations, you also have the option of installing the panels on the ground. During the perfect home solar panel installation, your home must have a very large and sunny roof with 30-degree pitch. Nevertheless, the most ideal conditions are not needed for benefiting from solar energy. By installing solar panels on the roof of your house you can actually save on electricity bills and you can also help the surroundings.
Is Solar Panel Installation Suited for the Place Where you Reside?
In spite of the fact that you do not live in a specifically sunny area, solar panels might still serve as a smart investment for you. Going solar will help you in saving a huge amount of money and these savings are completely dependent on two important things: electricity rates and availability of solar incentives and rebates in the area where you live. Consequently, the sunniest places always do not offer the best long-term savings from solar. Perhaps, people located in the Northeast can make good savings from the use of solar panels in comparison to the homeowners living I sunnier states.
Right Placement of Solar Panels
Basically, you can take the help of your solar panel installer for picking the right placement and it is essential that you feel extremely comfortable with the installer’s explanation of why and where. Generally speaking, there is one important rule to installing solar panels and that is the more sunlight is able to reach your panels, the more electricity will be generated and the more money you will be able to save on your electricity bills. More often, solar panels are found placed at angles on rooftops and there is good reason for such placement. Installing solar panels at definite angles on rooftops can help in saving money, reducing CO2 footprint and in satisfying the production of solar power.
Installing Solar Panels on the Ground
Solar panels work best when installed on rooftops, but they can also be installed on the ground, on exterior corridors and over parking areas and even close to walls. Any of the positions mentioned here might offer maximum sunlight depending on the setting and the condition of the property and the amount of solar power needed.
