Visit Home Build Solar System on http://home.kpn.nl/maas5455/and experience how also you can make not only solar panels but also how to make the whole system for half the price of panels you buy in the shop for free.
Those systems are mostly made from materials you can buy locally in your DIY shop and materials which are easy to get online.
Its time to harvest the sun and get your electricity for free.

Step 1: The Initial Intention
Step 2: Start Of The Challenge
Step 3: Building Process
When I finished soldering the cells, the cells where up side down (as I soldered the backside of the cells last) so could place on the back of each cell a little bid silicone and glued the cells on a 4mm glass sheet (this sheet will eventually become the back of the panel).
Now I left it all to dray and the silicone to vapor out (its really important to let the silicone vapor out real good as the vapors react with the solder on the cells).
Next I turned the glass sheet over and placed small tile crosses (they use to place tiles on a wall or on the ground to keep a standard distance between the tiles) in between the cells so that at a later stage of the building process the 2 plates of glass will form a stiffer construction. When they are in place I did put silicone sealant all around the edge of the glass plate at a distance of about 3 cm from the edge (which I left empty for filling at a later stage).
Then I placed the other plate of glass on top of it so the cells are now sandwiched between 2 glass sheets of 4mm thick (yes I just made double glassing with solar cell imbedded, how easy can a plan be).
Step 4: Vaporing Out Of The Panel
Step 5: Junction Box At The Back
Step 6: The Inverter
Step 7: Figure Facts
A guess what, I was also not prepared to pay the full solar panel world price for this neither.
I went to a local DIY store and bought an ELRO M12 Power Calculator, which is actually mend for calculating the usage of electrical appliances but works also fine to calculate any solar production (this calculator is working both ways it can give and take electricity from the net).
And this calculator plugs straight into the mains power supply with no difficult wiring (thats what we need).
Factory figures gave me that each cell gives 0.5V x 6A = 3Wp, but this in the perfect circumstances. For a whole panel this would mean 28 cells x 3Wp = 84Wp.
But from previous gained knowledge I know that this is always given as an to optimistic figure and that around 20% less production will be achieved in real live.
In this case this would mean a true expected production figure of 67Wp.
My panels are certainly not facing the optimum way, but this is for now also not the meaning (as silly as it sounds).
The panels are placed at a 10 degree angle (instead 35) and not exactly facing South.
But where they are placed is a temporary installation with the reason that I want to see how theyre behaving in real weather with cold temperatures, lots of rain and a blasting sun.
A real setup will come in the near future.
Taking all of this in account the panels are producing 15V x 3A = 45Wp each.
Concluding that the voltage of the cells are used to the maximum.
The amperage can go higher, this can be done by changing the angle of the panels more into the sun, but is currently not possible due to their placing location.
Step 8: In Production
Step 9: Future Thoughts
After this its time to make a sun tracker and make more panels but than bigger ones.
Than the panels will give more output due to the size and will always be facing under the right angle to the sun for maximum output.
And it speaks for it self that all gained knowledge will be published on the site for everyone to access.
And for the critic, yes youre right this is not free electricity as I had to pay for the parts but when I reached the breakeven point the costs are paid back and then the system will give me free energy by harvesting the sun.
To share my experiences Ive made a website where you can see for yourself how I did it, my production records to show how the system is behaving, and how you can do this yourself by means of text, photos and films.
