It's just that simple.
How do solar panels actually work?

Solar panels absorb sunlight and convert it into electrical energy. In simple terms, the more sunlight they absorb, the more electricity they produce. Solar panels should therefore be positioned to allow the most possible sunlight to reach them. You thus generate electricity on your roof yourself and save money on your electricity bills. Denim has been shouting about this from the rooftops for years. Shhh, listen. Can you hear us?


What are the advantages of solar panels?

And don’t forget, houses with solar panels are worth more.

How much energy do solar panels generate?

We keep everything simple. One plus one is two. The amount that solar panels generate depends on various factors. These include the power of the solar panels, their position in terms of the sun, the tilt angle, any shadows from trees or chimneys, the quality, and of course – and not entirely unimportant – the intensity of the sun and the number of hours of sunshine. Oh, sorry. We couldn’t make this any easier.

How many kWh does one solar panel generate in one year?

Hold on, here it comes. You need a few interesting facts and terms to calculate the amount of kilowatt hours a solar panel is likely to generate in one year. Take the total number of the system’s Watt peak and multiply it by 0.9. This calculation applies to a favourable position towards the sun and a tilt angle of about 35 degrees. A definition: the maximum capacity of solar panels is expressed in Watt peak (Wp). That was today’s maths lesson. See you tomorrow.  

What is the payback time of solar panels?

You don’t get the ten cents you put in today back tomorrow. It’s an investment. On average, the payback time is about 7 years, but that depends on various factors.
