Re: solar powered hi-way arrow boards used to generate power??can it be done using the panels??

I had a look at the video it is very interesting, I also took a look
at [link] a
video claiming to supply FREE ENERGY - off the grid from a generator
invented recently in Australia. The video is from Sky News Australia
and if the claim is right and works we could all be in for some very

You would need to know the wattage so that you could determine the amperage
or how fast the panels charge the battery, also i would recommend the optima
gel batteries though pricey, and a charge controller to protect the
batteries

What sort of voltage do you think they put out/ I could get 4 panels and 16
batteries...The panels are about 30 inches by 48 inches..Thanks

yes you could, though probably nominal voltage, unless you have a large

mchugh...@aol.com (leroybrown) — Tue, 10 Oct 2009 03:05:18 UT

Can I get a bunch of panels and batteries from old hyway arrow boards
and connect them to generate solar power ? Has anyone ever tried
this ..would it work??

My very first solar installation

My first Solar installation

For some time now I have had what i would call an emergency solar
lighting system in my house for use only at times of mains/grid
failure. This does in fact happen quite a few times during the year,
the system quite simply has one roof mounted 65w roof mounted panel

Certainly that is possible, I have a very basic system at home in the
south of England consisting of a 40w solar panel, charge controller,
two 110 amp leisure batteries and two inverters. One inverter is a
pure sine wave (600w) and the other is a modified sine wave (1200w)
they are basically for emergency power in case of a power failure, but

I should have mentioned that if 24v system was used then this might
just work.
I know the the inverter is around 90% efficient, but the main idea was
to support a low wattage solar panel until money would allow the
purchase of much larger system. Another idea I had was to help
charge up the batteries (from very overcast days) to make best use of

In theory this could be possible, but the inverter demands a high
ampage and will always use more power consumption than it provides,
that's a fact of life.

The real test would be when the 150w is being used as this is when the
ampage rises in the inverter, the battery would not keep up with the

m...@weathersystemsonline.co.uk (mail@weathersystemsonline.co.uk) — Wed, 11 Nov 2008 20:12:30 UT

I was wondering if it was possible to use a inverter connected to a
battery that feeds power to a battery charger via an controller that
in turn tops up the battery thereby if my calculations are right, the
battery never run down and yet get about 150w spare capacity from an
300w Inverter (FREE ELECTRICITY)?

The next questions should also be

How much do I think I already know?
How much do I want to learn?
How much do I want to pay? - the information is free, but you maybe
better off buying a book to help yourself get focused first. Then go

Correction made to the battery discharged voltage from 11.8v to 10.5
this can sometimes be disputable but it would be safe to assume that a
voltage somewhere in between would be safest, although it is not to be
recommended to take a battery near to the bottom of the range.

Looking After Your Leisure Battery

Looking After Your Leisure Battery
First of all, what is a leisure battery!
There are two main types of battery:-
1. Standard car battery
2. Leisure battery for marine, caravan or such things as solar power
Although it is not impossible to use either battery in any of the
above situations, the leisure battery has been designed to supply
