The product’s lifecycle depends on the battery life. The batteries are rated to give 500 cycles (full charge-discharge) or 18 months of continuous use. Life expectancy can go up to ± 4 years if batteries are partially discharged every day.
Suntoy originally developed the Consol Solar Jar for improving energy-access in areas without electricity within South Africa.
The product has 120 mW power output, 15 Lm light output and up to 80% of efficiency. After a fully-charging clear sunny day, the Solar Jar can produce 6-9 hours of light per day and ± 2 hours of run time (from 1 to 3 hours/day) from charge on rainy, overcast day. The batteries should give ± 400 full charges before they begin to deteriorate.
