Solar Module Descriptions: 

Solar Power Modules (known as Photovoltaics - PV) can generate electricity for your home or business, either as part of a stand-alone solar power system, or for buildings already connected to the local electricity network.

PV systems use the most abundant energy source on the planet, solar radiation, to generate electricity. They are silent, consume no fuel and generate no pollution. They also contribute to the reduction of greenhouse gas emissions; a 2kW PV system on a house will prevent the emission of about 40 tonnes of CO2 during its projected 30 year lifetime. Furthermore, the use of PV will reduce your electricity bills and exposure to fluctuating and steadily rising electricity prices.

FAQ

 

Q: What kind of loads can I run on PV?

With a correctly designed PV system you can power almost any electrical load. However, as the load size increases the expense also increases. Loads like hot water heaters, air conditioners, room heaters and electric stoves should be avoided. The added cost of trying to power loads like these is very cost prohibitive. If these loads have to be powered it will be a lot less expensive to change the appliance to use an alternative fuel type like propane.

Q: When do I need a charge controller and why?

The safest way to figure out if you need a charge controller is to take Battery Amp Hour Capacity and divide this by the Solar Panel max. power amp rating. If the quotient is above 200, you don't need a controller. If the number is less than 200 than you need a controller.

For example if you have a 100 amp hour battery and a 10 watt panel, you take 100 and divide it by .6 (600mA) and you get 166.6. Since this is less than 200 you need a charge controller. If you have a five-watt panel in the above example you take 100 divided by .3 (300mA) and you come up with 333.3. Since this is larger than 200 you do not need a charge controller. However you still need a blocking diode, to prevent the battery from discharging to the panel at night. So as a general rule of thumb you don't need a charge controller unless you have more than five watts of solar for every 100-amp hours of battery capacity.

Q: What is PV & how does it work?

PV stands for photovoltaic. Photo = Light and Voltaic = Electricity. A solar cell converts light to electricity.

A solar cell is made of silicon. Computer chips are made of this same material. Basically, when light strikes the surface of a solar cell some of it is absorbed into the silicon. This light energy bumps the electrons loose and causes energy to flow.

By packaging approximately 36 solar cells together a solar panel or a solar module is created. When you have more then one solar panels you create a solar array.

Q:How to choose a solar controller
And you have this system has two loads, you want to separate the controller, you can choose a dual controller! And so on and so on, more details can be consulted with me
Q:Solar controller one machine how
4LED display status, dual digital display mode of operation (a key operation intuitive, with power saving mode); can also be compatible with 12V system and 24V system (fully compatible) LED lamp operating current size, that is, the first period of work adjustable power ; The second time period, the third time period the power size adjustable, adjustable range of 10% -90%; the first time period, the second time period, the third time period, before dawn lights time adjustable; Tune, that is, after a few days after the delay in time to turn on the lights.
Q:How to debug a solar street light controller
Pure light control (0): When there is no sunlight, the light intensity drops to the starting point, the controller delay 10 minutes to confirm the start signal, according to the set parameters to open the load, the load began to work; when there is sunlight, light intensity to start Point, the controller delay 10 minutes to confirm the closure of the signal after the closure of the output, the load stops working.
Q:What is the system voltage of the solar controller?
General solar energy is now used LED lights, because the solar power is limited, with LED more power, the general 3, 4 watts when the general lights a 20 watts of brightness.
Q:What are the solar controller models?
You that the controller is the manufacturer, go to their website under the instructions can be
Q:How the solar controller wiring,
Controller (English name: controller) refers to the order in the order to change the main circuit or control circuit wiring and change the circuit resistance value to control the motor start, speed, braking and reverse the master device. It consists of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is a "decision maker" that issues a command to complete the coordination and command of the operation of the entire computer system.
Q:Solar controller red light flashing
Solar controller is divided into a variety of types, the lights are also representative of the battery, battery components and load, you said the red light flash is the end of the indicator light. You can also look for the controller's instructions, the above will generally refer to the reasons for the light flash.
Q:What is a solar controller?
The controller is the microcomputer on the water valve above the show solar water tank temperature control Sheung Shui to a certain level of electronic valve will automatically shut down the water is not on the water level to the most electronic valve will automatically open the solar water tank temperature is higher than 75 degrees above the water tank That is, no water, the electronic valve will not open to avoid solar vacuum tube break
Q:How does the solar controller set up Sheung Shui?
Press and hold the water level key for 3 seconds, hear the "drop" sound, the display temperature of the two digits and the "time to add water" indicator light at the same time flashing, repeat the water level key to set the time to add water time. Set the time in Beijing plus the number of hours set into the regular water, such as set at 12 o'clock in the hour, regularly at 8 o'clock every day on the water, set the number of hours 20 (range 00-23), wait 5 seconds to automatically save and exit the "regular water" indicator light is on, the regular water function takes effect, after 8 o'clock every day will start the regular water. To cancel the time to add water: hold the water level key for 3 seconds, hear the "drop" after the "time to add water" indicator off, the time to add water function to cancel.
Q:What is the use of solar controller
Some controllers also have a negative load power adjustment mode. Explain that the above is based on electricity and photoelectric interiors to describe the street system, but you can make independent of the other system
