Rationale Bilateral- and reginoal development measures lead to an
increased dissemination of PV-Systems ( > 1.000.000) Main environmental risk of PV systems are the lead
batteries, especially the lead recycling In many countries no regulated recycling or disposal
system for batteries in place A lot of available PV Systems are of poor quality with a
low lifespan (battery < 300 cycles) Lead price is increasing Role of the informel sector in recycling will increase But: Advantages of PV Systems outweigh the risks

PV - Batteries Batteries mainly consist of: lead metal (Pb),
lead dioxide (PbO2), sulphuric acid, lead sulfate (PbSO4)
Lead is toxic, harmful to the environment and causes cancer
Sulphuric acid additional contains lead particles Inappr. opening of batteries releases “lead-dust”

Electrification projects / status of replacement systems Within EnDev 9 projects
with PV - electrification component using batteries
Battery recycling system partially analysed
Honduras: replacement system for batteries through regular “battery replacement fee”

Way forward Increase user awareness Analyse current recycling practise
Solar and car batteries Select pv-systems with high quality Develop improved recycling / replacement
