Chinese Factory Half Cell Solar Module 100W -550W Mono Solar Panel

Solar Panels (also called solar Modules) is a core part of solar power systems and the most important part of solar power systems. Its role is to convert solar energy into electrical energy, or send it to a battery for storage, or to drive the load.
A solar panel's effectiveness depends on the size and quality of the solar cell and the transparency of the protective cover/glass.
Its Merits: High efficiency, Long life, Easy installation.

Are your inverters pure sine wave output?

Q:Yes, all our inverters from Guangdong Solarthon Technology Co., Ltd. provide true pure sine wave output.Contact us

A:What kind of output can you provide?

Q:Normally, we produce inverters with self-adapting voltages of 110V, 115V, 120V, 220V, 230V, and 240V, operating at 50/60Hz. If you have any special requirements, please let us know for engineer consultation.

A:What's the difference between a low frequency and high frequency inverter?

Q:A low frequency inverter offers various protections, strong adaptability to different environments, and higher reliability with voltage regulation.

A:What's the difference between a pure sine wave inverter and a modified sine wave inverter?

Q:A pure sine wave output inverter is comparable to the public power grid, if not better. It has a low repair rate, long lifespan, no harmonic pollution, and is environmentally friendly while protecting appliances. On the other hand, a modified sine wave output can negatively impact appliances and cannot handle inductive loads such as air conditioners and refrigerators. Certain motor control circuits are also not compatible with the modified wave.

A:What appliances can your inverters handle?

Q:Our inverters from Guangdong Solarthon Technology Co., Ltd. can be used with household, office, and agricultural appliances, as well as other inductive loads like refrigerators, air conditioners, water pumps, etc.

A:Can you print our company logo on inverters, nameplates, and packaging?

Q:Yes, we accept OEM orders from Guangdong Solarthon Technology Co., Ltd. and can customize the products with your company logo.

A:How do I choose the right inverter?

Q:Simply tell us your requirements, and our sales team from Guangdong Solarthon Technology Co., Ltd. will recommend a suitable inverter for you.

A:How can I solve technical problems?

Q:We provide 24-hour after-service consultancy from Guangdong Solarthon Technology Co., Ltd. to help you easily solve any technical problems you may encounter.

A:Do I need a power inverter?

Q:Actually, a power inverter is not absolutely required for a solar energy system. However, without one, you won't have access to 220 or 230 volts AC and will solely rely on battery power. While this may be acceptable for small RVs or cabins, most people prefer to use normal AC appliances.

A:What's the difference between 12, 24, and 48 volt inverters?

Q:The voltage refers to the input voltage from the battery bank. The main consideration is that higher voltages result in lower currents, allowing for the use of smaller wires between the solar panel array and the battery bank. It's important to ensure that the solar panels, inverter, and battery bank all use the same voltage when deciding on a system voltage.

A:What should I do if the product is broken?

Q:If any product from Guangdong Solarthon Technology Co., Ltd. is faulty, you can send us pictures or videos, and we will assess the issue and provide free spare parts for the PCB board as part of our after-sale service.Contact us
