What is the orientation of my roof to the sun?
The best type of roof for solar panels is a south facing roof as they tend to generate the most electricity from solar panels. South facing roof panels see the sun when it is at its most intense for the longest period of time, which is why they generate the most energy.
Which way does your roof have to face for solar panels?
Which way do solar panels face? The conventional recommendation is that a roof direction should face south for best exposure to the sun. Though south facing roofs will have the most direct sunlight exposure, the takeaway is that your roof does not have to face south for solar to make sense.
Can my roof support solar panels?
Yes, your roof can handle the weight of solar panels, as long as they’re installed properly. … You don’t have to worry about the weight of solar panels on your roof. Solar panels, including all the mounting equipment, weigh about 2- to 4-pounds per square foot.
Can you put solar panels on a west facing roof?
East and west-facing rooftops are also acceptable for solar panel installation and will still generate a significant amount of electricity throughout the day.
How do I know if my house is south-facing?
The easiest way to work out your aspect is to stand by the outside wall at the back of your house with a compass and see which way is south. If south is directly ahead of you, then your garden is south-facing.
What is the best direction for a house to face?
North or north-east facing properties are considered the most desirable because they get the most direct sunlight through the day, especially in winter when the sun is at its lowest.
What is the angle and direction of solar panels?
While the angle of your solar panels is important, a more important factor in your energy production is going to be the direction your panels face. For the best results, solar panels should be oriented towards the south. This is because the sun is always in the southern half of the sky in the northern hemisphere.
How do you find the true south of a solar panel?
Solar Noon Method
This method uses the fact that the sun is always due south at solar noon. A shadow cast by a vertical object at solar noon runs true north-south. So, at solar noon, use the shadow cast by a plumb-bob string or the vertical edge of a building to determine true south.
Why are solar panels installed in south direction?
The most optimum direction to face your solar panels is somewhere between south and west. It is at this location that your panels will receive the maximum sunlight throughout the day.
Does solar ruin your roof?
Solar panels are not inherently bad for your roof. The potential for solar panels to damage your roof stems from the method of installation. … These nails and bolts are typically driven directly through the roofing and into the attic or ceiling.

Why are solar panels bad?
Solar panels are bad for the environment because toxic chemicals are used in their manufacture. The fabrication processes have waste products which can be harmful to human health and the ecology. Old solar panels may become toxic waste due to the heavy metal content of the solar cells and other contaminants.
Which is better for solar East or West?
SOLAR PANEL PLACEMENT
If the solar panels face directly east or west, the production is closer to 20% less than directly south-facing panels. … West-facing solar panels receive the most sun at this time and, therefore, displace more grid energy during these peak demand periods.
What side of the house do you put solar panels on?
The traditional advice is to position solar panels to be south-facing. This is because, for those of us living in the Northern Hemisphere, the sun is always along the southern part of the sky as we complete our yearly orbit around it.
What happens to solar panels after 20 years?
Do Solar Panels Degrade over Time? As with most technologies, solar panels will naturally produce less energy over time. This reduced power output is called the degradation rate. … After 20 years, your panels should still be working at about 90% of its original output.
