Solar Panel The Direction Of Current

For those who are not part of a tou model with their utility company the direction that you want to face your solar panels is south.

Solar panel the direction of current.

In general there s one big rule. If you re in the u s. A solar panel consists of solar cells which convert light energy from the sun into electric energy. Therefore directions like southwest or southeast are fine.

The conventional wisdom in the northern hemisphere is that the best direction to face solar panels is south since that is generally where they d receive the most sunlight. Now a compass tells you magnetic north and south but it does not show you true north and south. However solar panels can be orientated on any roof that faces south of either east or west. The output voltage varies depending on the size of the solar panel its wattage rating and of cause the amount of sunlight available on a certain day.

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. However there is a difference between magnetic south and true south that must be considered. In the northern hemisphere the general rule for solar panel placement is solar panels should face true south and in the southern true north. The manufacturers provide the cell voltage current and power rating at the stc having irradiance of 1000 w m 2 and temperature of 25 o but in practice the solar cell temperature varies due to ambient temperature and further the cells are enclosed in glass due to which the temperature of the solar cell further increases.

Or elsewhere in the northern hemisphere the best direction for solar panels to face is true south though there is an exception. Usually this is the best direction because solar panels will receive direct light throughout the day. However the electricity system is not as simple as it sometimes seems and the best direction to face solar panels may actually be west. Selecting yes in the daylight saving field will cause the solar position calculation to assume the current time has been adjusted forward one hour from standard time.

Solar panels should face south for any home in america to obtain maximum power generation. 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. The rule is that if you live in the southern hemisphere you should point your panels true north and if you live in the northern hemisphere you should point them true south.

The electric energy produced is usually direct current dc. This is because the sun is always in the southern half of the sky in the northern hemisphere.
