5 Photovoltaics,Batteries, Cable and Wire
A note to our customers:
We no longer stock nor offer for sale photovoltaic modules.
We are doing this for a number of reasons.
First, they take up a lot of room on the shelf and once we repack them for
safe shipping, there is little profit in them.
Secondly, we would rather have the money invested in inventory that you
need and no one else stocks.
Having modules drop-shipped has become a nightmare so we will let
others deal with that.
Thank you for working with us,
A bit of advice for purchasing photovoltaic modules.
Stick with brand names such as Shell Solar, Kyocera, Uni-Solar, Matrix,
BP Solar, Evergreen and Solarex.
Check the voltage on the module, there are some "great deals" out there
on modules with odd voltages.
Many of these are left-over specialty modules designed for specific grid-
These are not designed for charging batteries or operating water pumps.
You may get a good price per watt for the modules but give up the savings
on the cost of a charge controller that can handle the voltage output.
A standard 12 volt photovoltaic module should have an open circuit, Voc of 20.0 to
22.0 volts and a maximum power voltage, Vmp of around 18.0 volts.
A standard 24 volt photovoltaic module should have an open circuit, Voc of 40.0 to
44.0 volts and a maximum power voltage, Vmp of around 36.0 volts.
A standard 48 volt photovoltaic module should have an open circuit, Voc of 80.0 to
90.0 volts and a maximum power voltage, Vmp of around 72.0 volts.
Please keep this in mind when you are planning to charge batteries or when
you are going to run the module(s) through a linear current booster, PPT unit, to
operate a pump.
Whatever the open circuit voltage is on a module, it will drop as soon as it is
connected to a charging system or LCB in a pumping set up.
A 12 volt battery bank needs to receive about 13.25 to 13.75 volts to charge.
A 24 volt battery bank needs to receive about 27.50 to 28.50 volts to charge.
A 36 volt battery bank needs to receive about 41.50 to 42.50 volts to charge.
A 48 volt battery bank needs to receive about 54.00 to 55.00 volts to charge.
We use modules at our location that are over thirty years old.
If someone tells you that an old "solar panel" is worth as much as a new
one and puts out as much power - don't believe it.

WEIGHT: when purchasing batteries please consider the location of the
installation and how easy it is to get to it. I have turned down great deals on
deep cycle batteries (high quality ones) because I knew that I could not handle
them. Some of these batteries weigh 150 lbs and more. I can straight lift into
my van (using a hoist) up to 600 lbs. and handtruck about 250 lbs. to the
battery bank location (that is with no steps or stairs), with batteries this heavy,
that is as far as I go, no lifting without using rigging (time consuming and
expensive.) Most people can handle a 75 lb. battery if done properly.
A standard 6 volt / 225 amp hour deep cycle golf cart battery weighs
about 65 pounds.
No deal is a good deal if you wind up getting hurt.
It is also best to purchase your batteries locally as shipping costs can be
PLEASE NOTE: we personally use AGM, gel cell and flooded batteries and
have been using deep cycle batteries for over 25 years, our good and bad
experiences may be useful to you.
We no longer stock batteries.
We purchase our batteries from Powertron Battery Co. in the
city of Santa Ana.
They have a wide selection of in-stock flooded, AGM and gel cell
batteries suitable for alternative energy uses as well as automotive
and industrial batteries.
They will also ship sealed batteries to customers out of the Southern
If you would like to purchase batteries directly from them please
call (714) 543 - 4858 and ask for either Craig or Drew.
They know their batteries and will give you excellent service.
We do not sell cable and wire but would like to recommend
Hardware Specialty Co. in Seattle, Washington.
I have purchased cable from them for several years.
Just ask for the cable and wire department.
