East-West arrays are ideal for meeting this pattern of electricity demand. For a similar reason, East-West arrays are very popular with Irish dairy farmers who go solar. This is because power-hungry milking equipment is mostly used in the morning and in the evening.
However, boosting the power of East-West solar panels to match South-facing solar panels can cost very little. The benefit of a better generation profile is often well worth this small added cost. You can do this with an East-West system because the panels will never all be at maximum output at any one time. This way, DC over-sizing helps you get the maximum return for your investment by controlling inverter costs. Solar panels in Ireland will produce some electricity no matter what direction they face.
However, North-facing solar panels produce substantially less power than South-facing solar panels. North-East and North-West are also fairly poor choices of orientation. Some homeowners choose to have panels on both east and west-facing roofs if they do not have a south-facing home. There is virtually no debate regarding the most effective direction of solar panels — but in terms of the correct angle for the effectiveness of panels, there is far less in the way of a one-size-fits-all solution.
If you were living directly on the equator this would be simple, as a horizontal panel at 90 degrees would have the sun directly above at all times. However, with your solar panel in the UK, the sun is at a different angle relative to the Earth — and this changes throughout the year.
Ultimately, this means choosing an angle that is going to give you the best possible benefit. In fact, this will depend on the specific of your home and the angle of your roof. It is best to have your panel pointing directly at the sun in the middle of the day during the summer, so your panel should be set up to achieve this. However, you should be aware that in doing so you will make your panels slightly less effective during winter. While you might not be aware of it, there are many different types of solar panel from a range of providers.
The two most common are the cheaper but less efficient polycrystalline solar panels and the more expensive but more efficient monocrystalline solar panels. While these panels work to achieve different levels of output, this is not down to their positioning, so you can choose the panel that is right for you separately from deciding its placement. The majority of solar panels owners choose to have their panels attached to their roof.
This has led to something of an assumption that they have to be placed on the roof. When solar collectors are used for heating and lighting specifically - particularly in the form of fenestration such as windows - it is actually best to have these collectors facing somewhat east. Warming the house for the day means morning sunlight is needed most.
The angle or tilt of a solar panel is also an important consideration. The angle that a solar panel should be set at to produce the most energy in a given year is determined by the geographical latitude. A general rule for optimal annual energy production is to set the solar panel tilt angle equal to the geographical latitude. Essentially, the closer a solar panel is located to the equator the more the panel should be pointing straight up. The closer the panel is to the poles, the more they should tilt towards the equator.
The angle of solar panels can also influence the power output due to climatic and environmental factors. In northern climates, snow accumulation on low-tilt panels can reduce or completely block the Sun's rays from reaching the solar panel during the winter months.
Although this effect will vary for every location, one study in Edmonton, Alberta, Canada concluded that the annual energy loss due to snow accumulation ranges from 1. Fossil Fuels. Nuclear Fuels. Acid Rain.
