1 Seite 1 Replacement of batteries of PV-Systems GTZ 3 rd EAST AFRICA REGIONAL ENERGY MEETING, Addis Ababa, Ethiopia, 27th – 30th October Presented by Andi Michel, Energising Development, GTZ

2 Seite 2 Page Content  PV – Systems  Rationale  PV - Batteries  Dangers  Electrification projects  Status of replacement systems  Way forward / Knowledge exchange

3 Seite 3 Page PV-Systems Consumer Charge controller PV-cells BATTERY 1000 cycles app. 3 years

4 Seite 4 Page Rationale  Bilateral- and reginoal development measures lead to an increased dissemination of PV-Systems ( > )  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

5 Seite 5 Page PV - Batteries  Batteries mainly consist of: lead metal (Pb), lead dioxide (PbO 2 ), sulphuric acid, lead sulfate (PbSO 4 )  Lead is toxic, harmful to the environment and causes cancer  Sulphuric acid additional contains lead particles  Inappr. opening of batteries releases “lead- dust”

6 Seite 6 Page Common recycling practise  Variation between rural and urban

7 Seite 7 Page Battery recycling factories Bhubaneswar and Kolkata, India Source : Blacksmith Institute 2008 OK International 2008

8 Seite 8 Page 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”  Your experience !

9 Seite 9 Page Way forward  Increase user awareness  Analyse current recycling practise  Solar and car batteries  Select pv-systems with high quality  Develop improved recycling / replacement systems  Exchange within projects   recycling of PV batteries of PV batteries
