Sizing your power station

To start the process of selecting a remote power station, you will need to make a list of your electronic equipment power draw. The remote system size you choose depends on the amount of electricity you require (Watts & Duty Hours/Day), and the available solar insolation in the area where the equipment will be located. (Average Sun Hours in December.)

 Watts ÷ Amps = Volts   1 kWh (Kilowatt-hour) = 1,000 Watts 

 

lowest peak sunhours

(1) Remote Power System Design Steps:

  • 1. Identify your location & select the lowest available solar insolation in the area the equipment will be located.
  • 2. Determine your load in DC Watts then duty hours per day. (To convert AC loads to DC, divide AC Watts by 0.80)
  • 3. Based on your DC watt load, select the remote power system you need. You should always round up to the next largest system.
  • 4. Determine days of autonomy. (Number of days of no sun for battery reserve calculation.)

(2) Sizing your System. Calculate Your Electronic Equipment's Daily Load

(EXAMPLE) Electronic Equipment Power Draw, DC Amps 1.5 Amp continuous (24 hours(1 day) load at 12 Volts DC (VDC)

telecommunication
  • DC Voltage 12VDC
  • Listed Equipment Power Draw 1.5 Amps
  • Duty Cycle 24 Hours
  • 1.5 X 24 = 36 amp-hours per day (Ah per day) @ 12VDC

(EXAMPLE) Electronic Equipment Power Draw Calculated in Watts

  • Electronic Equipment Wattage Draw 60 Watts
  • 60 Watts continuous (24 hours/day) load at 12 Volts DC (VDC)
  • Duty Cycle 24 Hours
  • 60 X 24 = 1440 watt-hours (wh per day)
  • Watt Hours Per Day (wh/day) 1,440 wh/day
  • Desired System Voltage 12VDC (48VDC)
  • 1,440 wh/day /12VDC = 120 amp-hours per day (Ah/day) @ 12VDC

*STC - To learn more about solar panels and how they are measured you need to know what STC stands for. STC in an acronym for "Standard Test Conditions". All solar panels are rated in Watts. The watt rating is how much power (amps times volts) the panel will produce in full sunlight at 25 degrees C (77F). This is the industry standard (STC) for all PV panel ratings (PV means Photovoltaics which is a fancy word for solar). Solar panel manufactures have long used this test standard which is 1,000 watts per square meter solar irradiance, 1.5 Air Mass and a 25 degrees C. cell temperature.

PTC is an acronym for "PV-USA". The PV-USA test conditions was developed at the PV USA test site at the University of Davis, California for standards established by the California Energy Commission that are considered closer to real world conditions (Real World Vs STC factory test conditions). The PTC rating test is 1,000 watts per square meter solar irradiance, 1.5 Air Mass, and 20 degrees C. ambient temperature at 10 meters above ground level and wind speed of 1 meter per second. In California, solar panels manufactures must be tested and rated independently at the PV USA test facility at the University of Davis (CA) to be considered for rebates.

The ambient temperature rating (PTC) is generally considered a better real world standard than factory conditions because silicon solar cells average about 20 degrees C. above ambient temperature in the real world, cell voltage drops as temperature increases. A module's power output in real life conditions is lower than the power measured at the panel manufacturing factory where cell temperature is maintained at a controlled 77 degrees F. (25 C).

STC Vs PTC Cell voltage drops about 0.08 volts per degree C. in environments which exceed 25 degrees C. That means an STC rating of 17 volts can actually become a PTC (PV-USA) rating of 15 or 16 volts. Using Ohm's Law, volts times amps is equal to watts which equals power, so a reduced voltage, means reduced watts.

Neither PTC nor STC account for all "real-world" losses. Actual solar systems will produce lower outputs due to soiling, shading, module mismatch, wire losses, inverter and transformer losses, shortfalls in actual nameplate ratings, panel degradation over time, and high-temperature losses for arrays mounted close to or integrated within a roofline.

Remote Power, Telecommunication, Scientific Data Transmittal, Security Systems

Remote power systems our Solar Energy Consultants have provided here are the ideal solution for telecom, security, telecommunications, scientific equipment, and data reporting. Each pole mount kit incorporates solar panels, a charge controller for the battery bank, DC distribution capabilities, and an optional telecommunications-grade DC/AC Inverter into a robust passively cooled outdoor enclosure and solar panel rack. The system can be located in the telecommunications compound along with the telecommunications ground-mounted equipment to provide a reliable source of power.

Remote power systems can be configured to provide a range of DC or communication grade AC power. Systems include the most recent advances in solar manufacturing, charge controllers and pole mounted battery enclosures. Remote power systems charge controller include temperature-compensated 3-stage battery charging, battery low voltage disconnect, lightning protection options and complete circuit protection. Each system comes with a 2 - 5 limited warranty on the controller, 10 years on the IronRidge racks and the solar panels carry a 20 to 25-year manufactures performance guarantee.

Solar panels used in our remote power systems provide the energy source to the batteries charged each day. The number of solar panels needed depends on the location of the system, the loads the remote power systems will be powering, days of autonomy and available of sunlight. Solar panels convert the sun's energy into direct current (DC) electricity. We use high performance monocrystalline or polycrystalline panels in our remote power systems. The solar panels are securely attached to a rack mounted on a pole (supplied by other) adjustable enable tilt alignment to match the latitude at which the module is installed for maximum solar irradiance. Solar panels sometimes come with a "J" box or junction box. The junction box is usually used on panels smaller than 140 watts, though this is not always the case. The junction box provides a junction to connect the solar panel to the charge controller via wiring supplied with the kit inside the battery enclosure. Multiple solar panels can be connected together, either in series or parallel depending on voltage requirements, and via a single multi-conductor cable connected to the solar charge controller.

Remote power systems come with racking to mount the panels. Racking is available in varying sizes and configurations to accommodate the types, number and size of solar panels and pole sizes on which they will be mounted. The most common is schedule 40 pole which are never supplied with the remote power system. The customer is required to provide the pole size consistent with the solar system size (which determines the pole size needed.)

The remote power systems enclosure houses the battery, charge controller, wiring, termination blocks and fusing if used for the system. The remote power systems enclosures arrive on site ready to be wired per the customers needs. The battery enclosure is typically sized to accommodate batteries which are staged in the bottom of the enclosure. Battery enclosures are sized according to the number of batteries and pole mount or chest style depending on the remote power system.

To properly size your remote power system, you will first need to calculate home many watts your equipment requires per day, and does the power you require DC (Direct Current) or AC (Alternating Current). You will then need to decide how many days of autonomy you want to be able to run your system and last but certainly not least the size of your budget. Here are some simple questions that will need to be answered during the design phase:

Telecommunications or Security Equipment Load will Affect the Battery and Solar Panel Design;

  • Daily energy draw from the battery bank measured in DC Watt-hours
  • The surge demand of the equipment
  • Number of days of autonomy (Means no Sun)
  • Daily depth of discharge (as percentage of battery nominal capacity)
  • Maximum depth of discharge (as percentage of battery nominal capacity)
  • Nominal DC voltage of the system
  • Lowest expected ambient temperature

Sizing the solar panels is critical to ensure there is an adequate supply of electrical energy to recharge the batteries. Because solar panel power inherently fluctuates with the sun, it is important to include the following factors when sizing and selecting the solar panels for remote power systems.

  • Is the remote power system going to be just solar panels or is a small wind turbine going to provide supplemental power.
  • Solar panels tilt angle
  • Solar Panels orientation
  • Any de-rating factors that may be applicable such as the effect of dust layer (soiling), temperature, etc.
