5. Ensure the product is not shipped collect, unless approved by management prior to Carmanah
receiving said product, or THE PACKAGE WILL BE REFUSED .
6. Test items or items that are not under warranty, or units that are not defective, will be charged a
minimum bench charge of ($50.00 US) plus taxes and shipping.
7. A 15% restocking charge will be applied on goods returned and accepted as “new” stock.
13. PHOTOVOLTAIC SYSTEM GLOSSARY
Ampere : A unit of electrical current. Designates the number of electrons flowing per second through a
conductive material.
Ampere-Hour
(
Ahr
): A unit of energy, typically referring to battery capacity. One ampere of current
flowing for one hour.
Azimuth of the Sun : The angular measure between due south and the point on the horizon directly
below the sun.
Array : A number of photovoltaic modules electrically connected to produce a single electrical output.
Angle of Incidence : The angle between a ray of sunlight striking a surface and a line perpendicular to
that surface. Rays perpendicular to a surface have a zero angle of incidence.
Battery : Two or more electrochemical cells connected to provide energy storage.
May be used to designate one cell. PV system batteries may be “sealed” or “wet acid”.
Blocking Diode : A diode application that prevents a battery from discharging through the array at night
or if the array becomes shaded. Most charge controllers are equipped with a blocking diode.
Charge Controller : The PV system component that controls the battery’s state of charge. It may also
provide other system control functions.
Charge Rate : The current applied to a battery to restore its energy capacity. The battery manufacturer
will usually have a recommended charge rate for their product. The rate is typically 10 –20 percent of the
amp hour capacity at the 20-hour rate.
Current : DC or Direct Current is the type of electron flow provided by a battery or solar cell, which flows
in one direction. The unit for current is ampere or amp for short and designated by the letter I .
Cycle One battery cycle equals one discharge and one charge.
Deep Cycle Battery : Batteries that are designed to discharge as much as 80% of their capacity as
opposed to engine-starting or “shallow cycle” batteries which are designed for heavy cranking but will not
stand up to repeated deep discharges.
Depth of Discharge : A measure of how much energy has been withdrawn from a battery, expressed as
a percentage of full capacity. A 100 Ahr battery from which 30 Ahr has been withdrawn has undergone a
30% depth of discharge (DOD). This term is the inverse of state of charge (SC); the example battery
would be at 70% SC.
Diode : A semi-conductor device that allows current to flow in one direction only.
Equalization : The process that equalizes the specific gravity of all the cells in a battery by means of a
controlled overcharge that breaks down sulfation on the battery plates. Most inverter/chargers and some
charge controllers are equipped with this feature.
Grid-Connected : A power system interconnected with the grid (or mains ) of the local electric utility. Also
referred to as utility-interactive.
Hybrid System : A power system consisting of two or more energy sources (e.g., a PV array and a wind
generator.)
