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:Solar controller can not charge what is the reason
Float control point voltage: the general charge is completed, the battery is also standing for some time, so that the end voltage naturally fall, when the drop to the "maintenance voltage" point, it entered the float state, are currently using PWM (both Pulse width modulation), similar to the "trickle charge" (that is, a small current charge), a low battery voltage to charge a little, a low charge on the point, an share of a place to avoid the battery temperature continues to rise, This is very good for the battery, because the internal temperature of the battery charge and discharge a great impact. In fact, the PWM method is mainly designed to stabilize the battery terminal voltage, by adjusting the pulse width to reduce the battery charge current. This is a very scientific charge management system. Specifically, at the end of the charge, when the remaining capacity of the battery (SOC)> 80%, it is necessary to reduce the charging current to prevent excessive release (oxygen, hydrogen and acid gas) due to overcharging.
Q:What brand of solar controller is good
The State Administration of Quality Supervision, Inspection and Quarantine announced the Chinese brand-name products, the entire solar water heater industry is currently only selected eight companies, as follows: force Norit Shandong force Norit New Energy Co., Ltd. billion to Shandong billion solar energy Co., Ltd. Sunrise Oriental sun rain Lianyungang City sun rain water heater Manufacturing Co., Ltd. Huayang Jiangsu Province, Yang Yang Solar Co., Ltd. Huang Ming Shandong Huang Ming Solar Group Co., Ltd. Sang music digital Shandong Sang Le Solar Co., Ltd. Tsinghua sunshine Beijing Tsinghua sunshine solar equipment limited liability company Brilliant Jiangsu Huaiyin brilliant solar energy limited company
Q:Solar water heater all intelligent controller how to install
The controller can also control the electric heating. When the electric heating key is pressed, the controller turns on the power of the electric heater 7 and the electric heater operates until the user specifies the temperature. When the temperature drops below the specified temperature 3-5 degrees, the controller restarts the electric heating and heats the water to the specified temperature. Users can also specify the heating time, at a time, the temperature of the solar water tank can not reach the set temperature, the controller will turn on the electric heater, the water tank to the water set to the temperature so far. The controller also has a protective effect, and when the water level drops to a certain point, the electric heating stops until the water level rises above that point. (Usually 50% of the water level).
Q:How to choose a solar controller
Hongyi HY-12 / 24V10A solar controller designed for solar DC power supply system, solar DC street lamp system design, and the use of a dedicated computer chip intelligent controller. Use a one-touch touch switch to complete all operations and settings.
Q:Solar panels for solar panels
Using the series PWM charging the main circuit, so that the charging circuit voltage loss than the use of diode charging circuit reduced by nearly half, the charging efficiency of 3% -6% higher than non-PWM, increased power consumption; over discharge recovery to enhance the charge, Normal direct charge, float the automatic control mode so that the system from a longer life; at the same time with high precision temperature compensation; intuitive LED LED indicates the current battery status, allowing users to understand the use of the situation; all control all use industrial chip ( Only with I industrial controller), in the cold, high temperature, humid environment to run freely. At the same time the use of crystal timing control, timing control accuracy.
Q:How to adjust the solar controller
The controller is designed for solar DC power supply system, solar DC street lamp system design, and the use of a dedicated computer chip intelligent controller. Use a one-touch touch switch to complete all operations and settings.

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:How the inverter is connected to the solar controller
No, no load will not work!
Q:How the solar controller wiring,
Power cord - usually with the controller with a three-pin plug power cord, has a good controller; sensor line - two lines and four lines, according to the label with a plug or terminal connected to the controller; solenoid valve - Two, according to the label connected to the controller; electric auxiliary heating line - three, according to the label connected to the heating bar.
Q:What is the power of the solar controller?
Generally in accordance with the current to count. Depending on your system voltage, such as 12V or 24V
