This chart is for sizing stranded wire for a 2% voltage drop in 12 volt systems.
Double the lengths for 24 volt systems and quadruple it for 48 volt systems.
Although a 5% voltage drop is acceptable for AC systems, 2% is the standard
for PV systems due to the savings of efficiency.

SIZING A REMOTE PV SYSTEM
We do not design electrical systems by the size of the home or the number of people living within.
Electrical usage varies over a wide range depending living habits. One person can easily use 10 or more
times as much electricity as another. We size photovoltaic systems based on your estimate of your
electrical usage. The more accurate the estimate, the better a system will fit your needs. You must know
how much electricity each light, appliance or motor uses and then estimate how much it will be used each
day (24 hour period). All electrical devices are rated in watts, like a 100 watt light bulb. If a motor or appliance
has a nameplate that only gives volts and amps, the watts can be calculated by multiplying the rated volts
times the amps.

STEREO TAPE PLAYER 1 80 2 160
FLUORESCENT LIGHTS 2 40 3 240
TOTAL AC USAGE PER DAY IN WATT HOURS 600
To adjust the loads for system efficiency and operational losses:
Multiply the DC loads by 1.3 to adjust - 800 x 1.3 = 1040 watt hours per day.
Multiply the AC loads by 1.4 to adjust - 600 x 1.4 = 840 watt hours per day.
The AC adjustment is more to account for inverter efficiency.
Adding the DC and AC adjusted loads together gives a total of 1880 watt hours per day.
MODULE SIZING
The next thing to do is pick a module from page 8. Pick a 100 watt module. Look atthe map on page 9 and
get the average hours per day of peak production. Let's pick the middle US with a production number of 4.
Multiply 4 times the module rating. 100 x 4 = 400 watt hours per day per 100 watt module. Divide the module
production into the adjusted load. 1880 / 400 = 4.7 - you would need 5 - 100 watt modules for this load in this
location. 5 - 100 watt modules produce a current of about 6 amps each so you will need a charge regulator
of at least 30 amps. 5 (modules) x 6 (amps) = 30 - Get a larger one if you have any plans for future expansion.
BATTERY SIZING
Batteries are rated in amp hour capacity. Pick a 220 amp hour battery from page 11. Since it is 220 amp
hours (AH) at 6 volts (V) it has a total capacity of 1320 watts (220 AH x 6V). You must adjust the battery
capacity for efficiency and depth of discharge and we use an adjustment of 70%. Multiply the capacity
1320 x .7 for a total adjusted capacity of 924 watts of usable storage per battery. Since the total adjusted
load is 1880 watt hours a day, you will need two batteries for each day of storage. You want 5 days of
storage so you will require 10 batteries for this system.
INVERTER SIZING
Inverters are sized to the largest AC load you will use at one time. If you plan to use all of the AC lights and
appliances at one time and have enough capacity to run a power tool you will need an inverter of at least
1000 watts. Since charge controls and inverters are not modular, like modules and batteries are, it is best
to get a larger one than needed if you have any thought of expanding your system at a later date.

enclosure with one side having a transparent or
translucent glazing(s), normally two layers of
glass. The side of the tank facing the glazing is
painted black to absorb the solar energy which
is conducted directly to the water in the tank.
Batch solar water heaters work great in the

tropics. Due to winter nighttime heat losses we
do not recommend them in climates above
approximately 35° N. latitude. The only thing
on one side of the collector between the hot
tank and the cold outside air is 2 layers of glass.
In climates harsher than this, throughout the
winter months the heater tends to lose at night
most of the daytime energy gained. Batch water
heaters are simple, reliable, easy to install and
are typically low cost. They can provide fifty to
ninety percent of hot water needs depending on
usage and climate. The piping to and from the
heater is the weak link in the chain. It should be
well insulated and heat tape should be installed
in harsh climates.

PASSIVE THERMOSYPHON SOLAR WATER HEATERS
Thermosyphon solar water heaters use the
natural convection of liquids to collect the solar
energy. Liquids expand upon a rise in
temperature and, therefore, the heated liquid is
lighter than the same cold liquid. With the

systems. When the sun heated water in the COLLECTORS
collector starts moving due to natural
convection, it is piped to the top of the storage
tank. The colder water in the bottom of the tank
flows to the bottom inlet of the collector. The
system does not require a control and will not
cycle backwards at night if the tank is at least
18" above the collector. The use of a passive
check valve in the system will prevent reverse
thermosyphoning if the tanks hot water inlet is STORAGE
above the collector outlet and the tanks cold TANK
water outlet is above the collectors cold water
inlet. This allows the tank to be just slightly

installation possibilities. These systems cannot

is heated, it moves by natural convection to the
top of the heat exchanger, transferring the

classified as low head (3' to 10'), medium head
(10' to 20') and high head (more than 20'). Low
and medium head pumps are normally used for
closed loop (glycol and DHW) systems. High
head pumps are used for drainback systems and
large baseboard or radiant floor heating
systems.
Pumps for domestic hot water or other open

loop systems should have bronze or stainless
steel housings to prevent scale from building
up. Pumps for closed loop systems may have
iron housings although a bronze or stainless
steel housing will normally last longer.
Pumps and Flow Rate

If the system controls are working correctly, an
inoperative pump may be due to a stuck
impeller, a burned-out motor, or a broken shaft.
These types of problems may be expected over
the lifetime of any component subjected to the
temperature and cycling stresses of a solar
system pump. Even though a solar pump is
operating and is being controlled correctly,
there still may be problems with the actual flow
rate in the collector loop. If the pump has been
sized to just barely overcome the pressure head
of the collector loop, an unexpected added
resistance can stop all flow through the
collector. For example, air in the fluid may,
over a period of time, collect in a section of
piping, especially if it cannot escape through a
vent to the atmosphere. This "air lock" can
prevent any flow if the pump does not have the
capacity to compress the air completely and
force it through the system. In an indirect

DIFFERENTIAL CONTROLS
Differential controls are used in virtually all active systems that use liquid collectors except
photovoltaic powered designs. A differential controller uses an electronic comparator circuit which
constantly measurers the output of two thermistors which are called sensors. The sensors change their
resistance upon a change in temperature and the controller turns equipment ( normally pumps and
blowers) on and off depending on the difference in temperature between the two sensors. This type of
control maximizes the efficiency of hot water systems by always transferring energy from the
collectors whenever even slight gains are available. Controllers normally turn pumps on when the
collector(s) is between 5 and 20 degrees F. above the storage cold water. When the collector
temperature falls to between 5 and 10 degrees above the tank cold water temperature the pump turns
off. Systems with heat exchangers normally have differentials of about 15 to 20 "on" and 5 to 10 "off ".
Direct pump systems have lower differentials since there is no loss through a heat exchanger.
Controllers made today also have a storage high limit of 160 to 180 degrees which is field setable.
Many controls also allow for a thermostat to be connected and also have options for digital readouts of
collector and storage temperatures.
Swimming pool differentials have very low turn on and turn off differentials and high limits. Typically
a 3 to 5 degree turn on and 1 to 2 degree turn off.

Integrating Radiant Floor Heating Systems with Solar Energy
All Solar Radiant Floor Systems are custom designed, there is no “cookie cutter” system of
this type because all homes are different and the way the solar energy is used varies with the
lifestyle of the homeowners.

WATER HEATING WITH AIR COLLECTORS
Air collectors may be used to heat domestic hot water using an air to liquid heat exchanger which is
much like a car radiator. A small blower flows air through the collector and passes it over the fins of
the heat exchanger and returns the now cooled air to the collector. A 1/100th horsepower pump draws
water from the bottom of the storage tank and flows it through the copper tubing in the heat exchanger
and back to the top of the tank. The heat from the solar heated air is transferred to the water. Although
air collectors are not quite as efficient as liquid collectors in heating water, the systems are simpler and
require less maintenance than glycol water heaters. An air collector solar water heater uses the same
type of differential control as a liquid system, but the differential is usually higher to account for the
lower heat capacity of air. The system must have a backdraft damper to prevent freezing the heat
exchanger tubing in cold weather. See the diagram on pager 57.

systems are called centrifugal and resemble a
treadmill in a squirrel cage. Although ducting
systems are used in many solar heating
systems, the blowers main purpose is to
circulate air through the collector. Small
highly efficient, permanent split capacitor
motors are used on these blowers. Systems
powered by photovoltaics normally use a 12
volt D.C. blower.
Fans with propeller type blades can only

circulate air through a minimum of duct work.
They are used in solar heating for “through
the wall” applications where solar collectors
are mounted on a southern wall instead of the
roof. Using a fan to circulate air through more
than a few feet of duct will produce
discouraging results.

THERMOSTATS
Line voltage, heat only thermostats are used on
air collector space heating systems. They may
be set by the user to regulate indoor
temperatures and turning the thermostat all the
way down effectively shuts the system off
when not in use. Cooling line voltage
thermostats are used to control blowers that
distribute excess heat from sunrooms.
HEAT-COOL THERMOSTAT $28.00

HEAT ONLY THERMOSTAT $55.00
LOW VOLTAGE
24 volt thermostats are used to regulate indoor
temperatures and are mainly integrated into
liquid collector space heating options. For these
applications they are normally wired in series
with either an aquastat or differential controller.

AQUASTATS
Aquastats utilize a remote bulb filled with freon
to sense water temperatures in solar storage
tanks. When the water is hot enough (80° to
100°F), the aquastat will turn on a pump to
deliver the hot water to its desired location.
When the tank temperature falls below the
selected temperature the pump shuts off.
