“How much electricity can solar panels generate in a day” is really a problem that many friends are very, very concerned about. Before that, let’s understand the main factors affecting the power generation efficiency of solar panels.

The first is the illumination angle. We know that the sun rises in the East and sets in the West. With different illumination angles, the power generation efficiency of solar panels is also different. In the case of vertical irradiation, its power generation efficiency is the highest;

The second is the light intensity. The greater the light intensity, the greater the working current of the solar panel;

The third is shadow shielding. If some external air conditioners and satellite TV on the top of the RV block the solar panel, it will certainly reduce its power generation efficiency, so it must be avoided during installation.

In addition, some dust and sundries on the solar panel will also affect its power generation efficiency.

So how much electricity can solar panels generate a day?

If you want to ask, how much electricity can solar panels produce a day? Under the influence of so many factors, it is difficult to give an absolutely certain number.

However, we can make a theoretical calculation: a 100-watt solar panel can theoretically emit 100W * 6h = 600wh = 0.6kwh = 0.6 kwh under standard lighting conditions (light intensity per square meter is 1000W) and the average sunshine duration is 6 hours.

After all, there is a gap between theory and reality. This figure must be discounted in the real scene. If we calculate various losses (line loss, illumination angle, illumination intensity, etc.), a 100-watt solar panel can generate about 0.6 * 70% = 0.42 kwh a day at a conversion rate of 70%.
