This estimation of the impact of your donation has been formed by over 30,000 direct research interactions with people who have bought solar lights from us.

When we first launched our Impact Calculator in 2015, it was the first time in history this impact had been understood in real data.

To gather quantitative impacts, we have spoken with people before they have purchased a solar light and after. By doing this, you can see how much a family’s life has changed. 

This is your impact. The most amazing thing is the impact of one whole solar light comes with a donation of just £4.
