Highly Portable Folding Solar Briefcase Kit: Extremely handy, 13W kit complete with
leads, adjustable support, charge indicator and blocking diode to
protect your battery. Powerful
enough to be really useful yet very easy to use and compact for easy stowage
so ideal for
motorhomes, caravans, boats and camping. The adjustable support enables
an optimum angle to the light, maximising output. This is an important
feature because pointing at the light gives 4-5x more change than laid
flat so this may give an equivalent charge to a flat mounted panel of
maybe 60W! What more can we say?

Solar
Power By Alden: 75-100 watts of electricity for free! Completely silent and
ultra-green
recharging will maintain fully charged batteries even when wild camping, or simply
give you peace of mind about your batteries in general. If any or all of these
benefits appeal
then solar power may well be the way to go! Although
solar power is amazingly common in Europe we seem to have been quite slow in
adopting the
zero running cost benefits here in the UK.
Solar is a hot topic at motorcaravanning because our increasing on-board
laptop use means we're now rather short of power on a daily basis. Alden solar and to some extent satellite seem to be almost
standard fit in France where they are the market leader and
recommended by numerous enthusiastic 'camping-caristes'.
Beginners
Guide: Out of the great mass of information I've waded through
recently there seem to be just a few solid guidelines for those of a
less technical disposition.
1. Don't worry about the different
cell technologies, the 'mono-crystalline' type are the most common
because they give more 'bang for your buck' in most circumstances and so
suit most people most of the time.
2. Whatever size you think
you'll need it won't be big enough! This is especially true further
north. You
can make all sorts of calculations
but in practice you should go for the
biggest you can sensibly fit and afford. For general holidaying that
will be between 50-100W.
3. Flat panels are the most
convenient being 'fit and forget' apart from an occasional wash.
4. Quite apart from overall capacity, there is some extra advantage in
having two panels rather than one. In practice only those with higher
power demands will spend the extra on this in which case point five also
comes into play ...
5. You can get four or five or more times the normal
output from a panel by making it face the sun. The Alden auto-elevating
unit claims to provide about 5x the daily charge of flat mounted panels.
This
unit is about the same cost as installing fairly substantial twin panels
so is usually for the heavier user or those who like to spend a few bob
on 'doing it properly'.
6. To complete a kit you need a regulator
& wiring and some high-bond Sikaflex, all are included in the Alden kits
along with a waterproof cable entry box.
7. Balance your solar
capacity with suitable leisure batteries, preferably 2x90/110Ahr leisure
batteries with a 100W panel e.g. and four such batteries with twin 100W panels.
(Watch your payload in the latter case!).
8. Comparison with wind
power is inevitable. Wind generators have quite high output when the
wind is blowing, but generally have to be set up and then stored away
for each use. They tend to be both heavy to manipulate and quite noisy
in use, sometimes irritatingly so for both you and your neighbours.
9. Fuel Cells & Generators are both worth considering. Their relatively
high output and full independence from the vagaries of the weather are
the main attractions. Generators are notoriously noisy (even the silent
ones!) and both require you to carry fuel. Generators are relatively
polluting whereas the nearly silent fuel cells have much greener
emissions, both carry fuel costs of course - in strong contrast to
completely free solar energy.

Kiteco: Kiteco solar panel kits are for people who want high
quality solar panels at a competitive price. With mono-crystalline cells
fitted in metal frames they are ready to mount on motorhomes, caravans
and boats. Alden recommend fixing with Sikaflex adhesive and this is
included as is a regulator and wiring. Available in three power outputs of 75W, 85W, and 100W. All
are lightweights at 8.3 to 9.5Kg
and come with a 25 year warranty. Dedicated versions for new Rapido are
also available as below. Buy Below >>> (PgDn)
Sizing: There have been some surprising variations in Kiteco sizes
of late and very few seem to correspond with Alden's published info(!)
The sizes given below are from actual stock in early 2008.

Sunpower 'Phenix': For the ultimate in solar power efficiency,
the 'Phenix' may be the only choice. Using sophisticated electronics,
the panel tracks the sun's elevation and direction throughout the day, ensuring that
maximum power is always generated. Naturally enough when parked for
travelling it charges just like a static flat panel. On an average day this unit will
produce more than five times the power of a fixed flat model. An eye
witness account - "January at 10.15 am and the Phenix was putting out
4 Amps!" The sky was clear but the sun was very low and a flat
panel would have produced <1 amp. When the
sun goes down or when the engine is started the panel will automatically
lower itself and lock into a safe position. A regulator and wiring are
supplied. Nominal panel rating 100W, dimensions 1250x680x16mm, weight
20Kg, clear height for rotation 90mm. Warranty; panel 25 years, mechanism 3 years. We're sometimes
asked about wind resistance and the official advice from Alden is "the Phenix and any of our satellite dishes should be parked when the
wind reaches force 5 and must be parked when it reaches force 8". Buy
