Solar Module Descriptions: 

A solar panel, or photovoltaic PV module, is a device that is composed of solar cells and which, when struck by photons of light from the sun, generates an electrical current which can then be used to power DC or AC electrical loads.

 This high efficiency waterproof 245W mono-crystalline solar panel is ideal for all on-grid roof installations on houses and commercial buildings, as it has been manufactured to the highest standards and certified by MCS and TUV to be suitable for any on-grid solar installations. The solar panel is also perfect for all off-grid installations on caravans, campervans, motor homes and boats for charging leisure battery banks or for off-grid household solar systems with batteries.

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:The principle of solar controller
The controller is divided into square matrix (series, parallel) and DC-DC conversion (with MPPT and no MPPT). The principle of withdrawal is the controller to detect the voltage of the battery, when the set value to withdraw from the square: parallel type of Chiang out of the square in parallel to the controller on the dummy load; series directly to the square open circuit. DC-DC conversion type: some parameters will be cured to the controller (usually the charging voltage is set to 55.2V), the square output voltage through the converter fixed to the set value to the battery charge; with MPPT with the above function , But also through the internal MPPT module to track the maximum power point of the matrix so that the matrix has been working in the solar cell's maximum operating point.
Q:What are the solar controller models?
Contact manufacturers, different manufacturers adjustable model is not the same as our company is this model: (light control + time control, time control, testing three models) Beijing reed hi Yuan New Energy Technology Co., Ltd.
Q:Solar water heater all intelligent controller how to install
Different solar water heater brand, the controller used is not the same. But the total is divided into the next type and side of the two, if you understand the installation of solar energy can first look at the probe to stay and then install the mouth. If you do not know you only looking for solar manufacturers aftermarket.
Q:How to choose a solar controller
Of course, you need other features, then it is necessary to say your needs, such as when the battery is not electricity you have to load to work, you can have electricity complementary controller; you want the lights in the first 5 hours Full power, midnight midnight power, then you have to choose with half the power of the controller; you need to light from heaven to 0:00, 0:00 automatically shut down the load, 4:00 and bright until dawn, you can choose double Of the controller
Q:Solar panels for solar panels
Solar controller is composed of dedicated processor CPU, electronic components, monitors, switching power tubes and other components.
Q:Solar controller 10a, a represents what
A, represents the current. Indicates the current that is allowed to pass during operation of the controller.
Q:What is a solar controller?
Solar controller uses high-speed CPU microprocessor and high-precision A / D analog-to-digital converter, is a computer data acquisition and monitoring and control system. It can collect the working data of the PV station in real time, obtain the working information of the PV station at any time, and accumulate the historical data of the PV station in detail, and provide the accurate and reliable evaluation of the reliability of the PV system design and the reliability of the quality of the inspection system Full basis. In addition, the solar controller also has a serial communication data transmission function, can be a number of photovoltaic systems sub-station for centralized management and remote control.
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 is the meaning of the 30A solar controller?
This 30A proves that the controller has a maximum current of 30A.
Q:Solar water heater controller power screen is not displayed
Check the circuit, if the circuit is good, then you have to get the seller to see, because you know where is bad, you no tool material, can not change.
