Do Solar Panels Need To Face The Sun

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.

Do solar panels need to face the sun. No but all solar panels perform best when the sun is at its best and that is in the summer. 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. 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. If your roof does not face the right direction then surface mounted panels or pole mounted panels may be.

However each of the above only considers. Solar panels perform at their best when the sun is shining straight on to the panels. Can solar panels work in winter and does solar really work in the uk. So do solar panels work when there is no sun.

Take solar lights for an example. A solar panel will harness the most power when the sun s rays hit its surface perpendicularly. If your panels face south they ll receive light throughout the day. The placement and orientation of solar panels is just as important as which type of solar panel is used in a given situation.

Let s dig a little deeper to show how to determine true south and look at the best tilt angle for solar 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. In order to collect energy more efficiently solar panels should be angled to face as close to the sun as possible. West facing solar panels get less sun than those that face south but it s not as little as you may think.

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

Yes so long as the size and power of the solar panel is relative to the thing it needs to power. It is at this location that your panels will receive the maximum sunlight throughout the day. When the sun shines onto the surface at an angle the panel will still generate electricity but it will be less effective.
