How to calculate the proceeds of solar panels?

With solar panels on the top of your roof, you will now generate 100% sustainable solar energy. The proceeds of your solar panels are denominated by kWh. With Soly, it is possible to monitor the proceeds by month, day and even on an hourly basis. Saving money or even making money with solar energy is - of course - a lot of fun. The actual proceeds of solar panels is however based on several factors. Daily sun hours, the orientation of your roof and even the slightest fraction of shade. They all influence the final proceeds. We’ve decided to integrate this formula in a roof scan for solar panels: Solarcheck. It’s easy to use, and it’s free. How do we calculate the proceeds of solar panels?

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.

Costs and revenue solar panels

Lease of Purchase?

Next to the revenue generated by solar panels, we also like to focus on the expenses. This will provide for a transparent display on whether solar panels are an interesting investment. As you might know by now, we are both offering Solar Lease and Solar Purchase. This has a huge impact on both the cost- and revenue side of solar panels. In fact, the yield, the number of solar panels chosen and the associated costs run more or less proportionally to each other. It is also based on the situation.

We have the description of both concepts on this website. Find out which suits your annual consumption.

04.

Choose the number of solar panels

Based on the information provided above. It's a first step towards 'zero on the meter'.

05.

We will calculate your price, payback period and proceeds

This will all be shown in the last step of the Solarcheck. An accurate overview of what to expect.

06.

You receive an overview free of obligation

Next, you can still think quietly about whether you should go with us or not. We'll be happy to lead the way.

Happy? Take the next step together with Soly. Our Solarcheck will help you make the right decisions. Receive an indication of the possibilities for solar panels at your address.

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.
