Do Solar Panels Need To Face The Sun

West facing solar panels get less sun than those that face south but it s not as little as you may think.

Do solar panels need to face the sun.

Best direction for my panels. Take solar lights for an example. Yes so long as the size and power of the solar panel is relative to the thing it needs to power. 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.

So do solar panels work when there is no sun. 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. The placement and orientation of solar panels is just as important as which type of solar panel is used in a given situation. Net energy metering and time of use.

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. When the sun shines onto the surface at an angle the panel will still generate electricity but it will be less effective. 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. It is at this location that your panels will receive the maximum sunlight throughout the day.

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. However each of the above only considers. If your roof does not face the right direction then surface mounted panels or pole mounted panels may be. Solar panels perform at their best when the sun is shining straight on to the panels.

According to the concord consortium makers of energy3d solar energy modeling software a home in boston ma with panels that face west would get 80 of the electricity that a house with south facing. Recently the new york times and popular science even purported that solar panels should face west rather than south to avoid unintended consequences. 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.

The most optimum direction to face your solar panels is somewhere between south and west. 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.
