Proceeds and return out of solar panels
Would you like to find out the proceeds of solar panels? Keep an eye on the capacity and peak power. On average, a solar panel uses only 88% of its capacity. This may sound strange, but keep in mind that it’s an average, giving all the factors that could influence the proceeds, such as the orientation of the roof, the inclination angle relative to the sun and the sun hours on a daily basis. With solar panels, its peak power is calculated based on the most favorable circumstances. In practice, these circumstances do not always apply.
In fact, 88% of the capacity of a solar panel means 1 Wp ≈ 0,88 kWh of generated electricity. Suppose you have a solar panel with 390 peak power, providing proceeds of 390 x 0,88 = 343,2 kWh. With these numbers in mind, you can now easily calculate the number of solar panels you need to offset your annual power consumption.
Solar panels yield per year, month and day
In fact, that is very easy. However, we will give you an easy formula on how to calculate the proceeds of solar panels over time.
Solar panel proceeds per year
Total peak power x 0,88 = .. kWh per year
Solar panel proceeds per month
(Total peak power x 0,88) / 12 = .. kWh per month
Solar panel proceeds per day
(Total peak power x 0,88) / 365 = kWh per day
Of course, this is just an annual average. Solar panels – obviously – will be generating more solar energy in summer, compared to the winter. This is however an easy way to make a quick calculation of the potential proceeds of solar panels.
