Charging via Solar

Good to know before you start Solar Charging

A wide variety of factors have an impact on how fast the sun is able to charge your Solar Charger. The most important factors are:

  • Season & Location
  • Time of day
  • Cloudiness

Seasonal impact & Location

One of the biggest factors that shouldn’t be underestimated is the impact the seasons have on the power of sunlight. Optimal conditions are of course during the summer, but in winter the sun can be around 50% less powerful!

Not only does the sun simply shine fewer hours during the winter, it also doesn’t appear as high in the sky. This lower angle means the same amount of sunlight is spread out over more surface, making it effectively less powerful

This difference less apparent around the equator, but increases the further you move towards either pole.

Time of day impact

As mentioned in the text above, the angle of the sun has a big impact on the effectiveness of solar panels. Of course the angle doesn’t only change with seasons - it also changes throughout the day. This means that the peak solar hours are often between 11am and 2pm.

The impact of clouds

As you can imagine, clouds have a very big impact on the effectiveness of solar panels. Depending on the intensity and denseness of the clouds, the impact could be as much as a 90% reduction in power generation.

So how long does it take to fully recharge my solar charger?

Because the estimated charging times can vary a lot depending on the circumstances, we have done calculations for 3 different scenarios:

  1. Perfect sunny day in summer
  2. Mostly sunny day in spring or fall
  3. Mostly sunny day in winter

We will not offer estimations for very cloudy days, because it is really not effective enough.

In the table below you can see how many days it takes to fully recharge your Solar Charger.
