This video was made as another example for making homemade solar panel on minimum budget located in UK. Website will be coming soon. On this channel will be shown 5 examples of magnetic , solar and water generator which I tested , including not working ones to avoid same mistakes which I made to save some coins to another guys which have similar hobby 
To share knowledge for good purposes . This series is about building solar panel as a basic source energy for charging batteries , led lighting , powering low energy motors and then in future only multiply if possible . It has 3 parts :
part 1 – making frame
part 2 – soldering solar modules
part 3 : insulation
Output from this panel I get 10.54V and 0.23A , so it can charge 6V battery or – make 2 to charge 12V or – change dimensions basic frame or – put another row side cut solar modules … etc . Total cost of material was about £50. Full price list will be located at future website. When I will finish editing all videos I will put link here .
I did not count total hours because I did not mind
Video was recorded with android tablet Nexus 2013 on stand and edited with Windows movie maker – free download at http://download.cnet.com/Windows-Live-Movie-Maker/3000-13631_4-10965753.html
Front and end photo banner on video was made with Magix Photo Designer 7- free download at http://download.cnet.com/Magix-Photo-Designer/3000-2192_4-173446.html
Music I made when I buy and tested software Magix Music Maker 13. Licensed ! That was for You tube guys , before they try cut me again
Playlist from another channel http://www.youtube.com/playlist?list=PLMcK6S99KR1r1dwP4SHVizFZZ8ulPkTBQ
For some songs I did made also video versions , playlist is on my another You tube channel at https://www.youtube.com/watch?v=JEyQHHC6TnU&list=PLVR4yXIvD_ISzWD18KNH6cBLp_6oelMxv&index=1 when I wanted to cover slideshow and test possibilities of video making and editing with Music Maker.
All music separate – instrumental – with clean sound is at https://soundcloud.com/3styller and if You don`t like switch off the sound
I forgot put in this video part wire connections , diode , battery examples with charger…. so I put it on beginning 3 part.
