Do Solar Panels Need To Face The Sun

Recently the new york times and popular science even purported that solar panels should face west rather than south to avoid unintended consequences.

Do solar panels need to face the sun.

If your roof does not face the right direction then surface mounted panels or pole mounted panels may be. So do solar panels work when there is no sun. Yes so long as the size and power of the solar panel is relative to the thing it needs to power. The placement and orientation of solar panels is just as important as which type of solar panel is used in a given situation.

Since the majority of solar panel owners keep their system on the grid we can split this grouping into simply those who pay for energy based on a tou payment. When the sun shines onto the surface at an angle the panel will still generate electricity but it will be less effective. Take solar lights for an example. However each of the above only considers.

There is still a wide misconception solar panels need heat to make energy. Can solar panels work in winter and does solar really work in the uk. When in fact solar panels need light not heat. The sun moves from east to west during the day and is higher or lower in the sky depending on the season lower in winter higher in summer.

The most optimum direction to face your solar panels is somewhere between south and west. In order to collect energy more efficiently solar panels should be angled to face as close to the sun as possible. A solar panel will harness the most power when the sun s rays hit its surface perpendicularly. No but all solar panels perform best when the sun is at its best and that is in the summer.

Let s dig a little deeper to show how to determine true south and look at the best tilt angle for solar panels. Net energy metering and time of use. Solar panels perform at their best when the sun is shining straight on to the panels. The direction that your solar panels face is ultimately dependent on whether or not your system is connected through net energy metering nem and under a time of use tou payment structure.

Best direction for my panels. The more sunlight reaches your solar panels the more electricity you can generate and the more money you ll be able to save on your electric bill. Photovoltaics produce power when the angle at which the sun s rays hit the panel surface the angle of incidence is small or when light strikes the panel as close to perpendicular as possible. Yes panels make less energy in the winter simply because the days are shorter but even on the shortest days solar panels generate all or most of the power you ll need to wash your dishes and clothes use the dryer lights heat pump and appliances.

If your panels face south they ll receive light throughout the day. Ensuring that solar panels face the correct direction and have an appropriate tilt will help ensure that they produce maximum energy as they are exposed to the highest.
