Forewordby Ben Law
This excellent practical book contains all you need to know to set up a 12 volt,off grid solar system. It contains a wealth of information from constructing12 volt circular saws to electric guitars. There is even a solution for makinga 12 volt washing machine, the 'holy grail' amongst many of us living off theNational Grid.
Michel Daniek cleverly combines his mechanical training with solar energyto offer many DIY solutions for anyone living or aspiring to live with anautonomous energy supply.
I have been living with 12 volt electricity for 16 years, and I have had tolearn, change, upgrade and experiment to reach the system I now have atmy Woodland House, running on 12 volt solar and wind power with a largebattery storage capacity. I made many mistakes along the way, like sufferingvoltage loss from insufficient sized cables in my first caravan. I struggled tofind the necessary knowledge and experience to help me unravel what at thetime felt like complex physics.
Yet,here in one book are all the answers I needed. Volts, amps, watts and ohmsare explained with logical clarity - and batteries don't wear out because Michelhas solutions to repair them! This is what is so empowering about this book,it allows and encourages you to create simple 12 volt tools from everydayitems such as windscreen wiper motors and -motorbike starter motors. I amparticularly impressed with the bicycle wheel sun following system to gain themaximum potential from your solar panels. And if you have problems withyour panels, Michel has answers for how to repair them.
For anyone who is living in a truck, bender, caravan, yurt or other low impactdwelling,or if you are inquisitiveabout options beyond the national grid and alternative energy supplies, DIY 12 Volt SolarPower is full of practical solutions andis sure to become a well thumbed classic for many off griders around the globe.

About This BookWhen I started to work with solar energy, I thought I had found asolution for at least one part of our global problems. Very enthusiastic,I started to give solar workshops all over Germany. I found it quite easyto convince and inspire people but after a year I was sick of telling thesame thing over and over again, so I decided to write this book. It wasabout this time that I moved from cold Germany to this crazy townhere in the south of Spain which with its abundant sunshine, has proveda perfect playground for my solar experiments. When I first arrivedthis area still needed a lot of development - many people were stillliving with candles. It was a pleasure for me to bring the luxury ofelectric light and music into their lives.
However energy use consciousness was sadly lacking. Things developed really quickly and the level of consumer demand soon outpacedthe capacity of my small solar systems. Many people changed to usingelectricity from the National Grid. My idealism with solar energy wasbadly punished but it opened my eyes to the fundamental problembehind the destruction of our planet: consciousness.
I started to write a book about it but the theme is so huge ... HoweverI still think that small scale solar energy is an important field of learningto increase awareness of one's own energy use. It's just one little step,but it is a step in the right direction.
So... let the sunshine in!!!
Thanks to all of you! Thanks for all the great help, enthusiasm, idealismand all the love that the world needs so badly in these times ofchange.
This book was originally written in German in the sunny winter of1997-98 in EIMorreon, Spain. It was translated into English by CathyGreen, Rod Wilson and Abi Hill nearly at the same time. The drawingsare by Carma Sola, Demian Oyarce, Michel Daniek and Marion Miller.Proof reading was done by Achim, Felix, Elke, Frederik, Christian,Gunther and Patricia.
In 1999 it was translated into Spanish by Concha Buenaventura andNatalia Rodriguez. A new typed Spanish version will soon be available with great help from Nadin, Timbe-Drums and ConchaBuenaventura.
In the summer of 2005, I rewrote and typed out the English version,adding some new material, including many experiences from theprevious seven years of living and working with solar electricity insouthern Spain. Special thanks for Jeem, Daniel Wahl and PatrickWhitefield for their good help with that.

The electricity industries do not produce many power saving appliancesor teach people to use energy more efficiently. Instead they put productson the market such as TV's with standby buttons and appliances that usepower even when they're switched off. These appliances are continuallyadding to your fuel bill, CO2 emissions and creating electromagneticfields (electrosmog) even when they are not being used. We can standup to these commercial and political manipulations by using alternative,decentralised energies to show thatit is possible tolive free from thegrip of large energy concerns. We can lead by example!
Alternative energy includes fast growing biomass fuels such as rape,hemp and coppiced willow; heaters using insulated storage tanks; solarcars; wind and water energy. Last but not least is photovoltaic energyfor producing solar electricity. This must become affordable foreveryone and part of our everyday lives. It is important that growth isencouraged - the more consumers spend money on solar panels, themore producers will be encouraged to market them, drastically reducingthe cost. But within this process there must also be a change in patternsof energy consumption because todays wasteful attitude cannot be thebasis of a solar future.
For many people, solar energy is already a part of their lives. People withmany different motivations are creating new power systems and houseswith autonomous energy supplies. There are solar associations spreadinginformation and setting up groups to create solar systems. Howeverwhereas a solar water heating system will pay back the initial financialoutlay within only a few years, a solar electricity system connected to theNational Grid is only financially viable if it's on a large scale. Thereforemost solar power systemsare now in alternative communities where theyhelp to fulfil the desire for an autonomous and ecological life.
Low voltage solar power systems can allow us to maintain our standardof living without the electrosmog of the National Grid. Solarpowersystems with battery storage are being put together by people lookingfor new ways of living and a way out of this apparent dead end as webecome less and less able to ignore the worldwide ecological crisis allaround us. More and more people want to act instead of just sittingback and watching the earth being destroyed. Many people would liketo have a future!
models were made with plastics containing Fluoride. However todaythey are made with PVC instead which is recyclable and non toxic.There are some toxic satellite solar cells but these are not the sort youwill find in the shops.
Another rumour is that solar cells are ecologically unviable because theyrequire such a large amount of energy to produce. I have informationthat, depending on the methods of production, solar cells will recoupthe energy used within 3 to 7 years.
Poly and mono crystalline cells have now been in use for around 40years and (apart from those which have been damaged) are still workingperfectly. The very early solar panels had some problems with brokenback covers, so water or humidity could damage the silicon cells. Plussome old series of AEG solar panels were made with aluminiumconnectors between the single cells inside the panel which also causedproblems after 10 years or so. All modern solar panels use silverconnectors and do not have these problems.
Every single silicon plate in the panel increases the voltage of the panelby 0.55V. Every solar cell has more or less this same voltage regardlessof its size because the size of the solar cell affects the power in amperesbut not in volts. Ther
