DIY solar panels
This website offers information about how to build your own solar
panels. Below is a picture of my first panel, placed on top
of the shed. It
has been a bit photoshop'd because the photo was taken in the twilight,
however only
the colors and brightness have been changed a little:
And now for something else: Friends of us are helping out with a
charity project. They want to bring solar energy to Africa (amongst
other projects). Do you have something to share then click once on the

Solar panels.
To my opinion solar panels are very expensive. A
panel of 100 Wp (Watt peak) costs around 400 Euro. I do not know
the exact price but it will not be much lower and that is too
expensive.
This is a rough calculations (based upon dutch electricity prices) and
will without a doubt be far from the truth, but
still: 100 wp is about 80 kWh on an annual basis (a little less I
think, but ok). This is with an energy price of 20 Euro cents about 16
Euro per
year. So that would be 400/16 = about 25 year. Which would be too long
for the lifespan of the panel (without maintenance). This is
only the price
of a panel. In addition an inverter is needed. This inverter will
return the collected energie back into the electricity grid.
Converters have different prices, and range from approximately
50
to 75 Euro per 100Wp. Also you'll need some installation and
mounting
materials. Let it then be done by a "professional" and a price
of 500
Euro per Wp is not unusual and then you would have a
cheap installation. Note: these are all dutch prices.
Detail regarding installation material in the solar world, Tyco and
multi connectors (3 and 4) are very common. These are of standard IP67
and IP68
(as I remember) what I think means that the connectors
are waterproof. And that is beautiful. These connectors are expensive
but the costs are acceptable (so somewhere between 2 and 4 Euro per
piece).
Until you realize that you need a tool with which you have the
connectors connected to the wires. This tool will cost somewhere
between 300
and 400 euro.To met this indicates that the solar world is not
cheap and
that home is something to achieve when doing things yourself. I have
decided to avoid as much as
possible these connectors. I'm going to take a long electric wire to my
panel. During installation this will give some struggle, but
this is hopefully once.
This website was translated from dutch into english, partly using
google tools. My english is reasonable, but definately not good, so
there will be many errors. If you feel the need to correct some then
send me a mail...
As indicated, my goal is to build solar panels. I have
been looking for information for a long time and found little until I
recently searched
again and encountered the
website
of Chis van der Zwaal. He has just done it
and described his concept clearly. I liked it so much that I
will try this as well. Take a look at his
website
because he has a lot of information about making solar panels.
For anyone who perhaps would like to try theirselfs I
created this website. I intend to
keep track of the costs (an important aspect, I think, because
the
costs are too high to be something purely for the hobby)
and how I'm going to build the panels. At the time of this writing I
know pretty much what I want to do. First a pilot project then a
complete
install (I do not know exactly how much in total it will be, but
somewhere between
600 and 2000 Wp). Most
orders are made and some are already received. The first is a
pilot project to
determine feasibility.
