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.

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 10a, a represents what
10A indicates that it can control the maximum current is 10 amps, the use of the load can not be greater than this current.
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 to adjust the solar controller
Charging and overpressure indication: When the system is connected normally and the sun is exposed to the photovoltaic panel, the charging indicator (1) is green, indicating that the system charging circuit is normal; when the charging indicator (1) Description of the system over-voltage, the treatment see the fault handling content; charging process using the PWM method, if there have been over-discharge action, the charge must first increase the charging voltage, and keep 10 minutes, and then down to the direct charge voltage, Live activation of the battery, to avoid sulfide crystallization, and finally dropped to the float voltage, and keep the float voltage. If there is no over-discharge, there will be no way to enhance the charge to prevent the battery water loss. These automatic control processes will allow the battery to achieve the best charging effect and to ensure or extend its service life.
Q:How the solar panels with the controller
Hong-wing HY-12 / 24V10A solar street light 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. With full short-circuit, overload, unique anti-reverse protection, full, over-automatic shutdown, recovery and other full-function protection measures, detailed charge instructions, battery status, load and a variety of fault instructions. The controller through the computer core search chip on the battery terminal voltage, discharge current, ambient temperature and other parameters related to the battery capacity sampling, calculated by a dedicated control model to achieve the characteristics of the battery discharge rate, temperature compensation correction of high efficiency, high accuracy Rate control, and adopted a high efficiency PWM battery charging mode, to ensure that the battery work in the best condition, greatly extending the battery life. With a variety of work patterns, output mode selection, to meet the various needs of users.
Q:Solar water heater all intelligent controller how to install
Different manufacturers are not the same, you can call to contact after-sales processing
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:What is a solar controller?
Can control the solar street light, the switch controller is the solar controller; domestic well-known brands should be far away power and the exchange of energy to the sun in the science and technology in Beijing; we are the power to do LED lighting business is brand goods
Q:Solar controller red light flashing
Installation of the controller should pay attention to: 1, waterproof; some of the controller on the market is not easy to produce waterproof, easy to penetrate the water vapor in the poles, resulting in short circuit and other issues; 2, pay attention to the controller and system rationality, 3, the main function of the controller is to protect the battery, must pay attention to.
Q:How to debug a solar street light controller
Manual mode (5 ·): In this mode, the user can press the button to control the load on and off, regardless of whether it is during the day or night. This mode is used for some special loads or when used for commissioning.
