Why Solar Panels Are Kept Inclined

Why solar panels are kept inclined.

The radiation should be perpendicular to panels for maximum efficiency. Since solar panels are more productive when the sun s rays are perpendicular to their surfaces the certainly best orientation is the one directly true south azimuth angle 180. The inverter runs to a smart meter that records the amount of energy you use and also the excess solar energy that is sent back to the utility. Solar power is self sufficient and installing solar panels on your roof is a safe and easy path to contribute to a sustainable future.

Solar panels generate electricity when sun rays falls on it. The other reason is that your solar panel system is connected to the grid via a solar inverter or grid tied solar. In the past panel manufacturers would not offer warranties on panels installed at an angle lower than 2 degrees but these days most of the top manufacturers will give warranties even if their panels are installed at 0 degrees completely flat. Hence it s safe and environmentally friendly.

Yet people are still in doubt why solar energy is good. A solar panel should have high efficiency. Solar panel converts the absorbed light from the sun to electricity. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.

As you might have observed the trajectory of sun is different during summers and winters. So if the grid shuts down so will your solar panels. Solar panels contain cells of semiconductive material usually silicon usually encased in a metallic frame and tempered glass. When subject to sunlight photovoltaic cells create a flow of electric charge inside the solar panel due to the photoelectric effect this flow travels in a circuit of wires that connect groups of solar panels called arrays.

Panels are usually oriented towards the south in the northern hemisphere because the sun mostly is in the southern part of the sky. To keep it simple. It only happens when the sun is relatively low so it doesn t have a huge influence on the total yield. The solar panel is set up inclined so as to absorb the maximum amount of sun rays.

Many people are aware that solar is a great home efficiency upgrade and are eager to reduce their carbon footprint while also improving property value. So in a system with fixed solar panels we take latitude angle of the location. The sun sometimes is in the northern part of the sky e g.
