FAQ：

1.Price per watt?

It depends on the quantity, delivery date and payment terms.

2.Parameter of the module?

We have different series of panels in different output, both c-si and a-si. please take the specification sheet for your reference.

3.Can you provide the peripheral products of the solar panels, such as the battery, controller etc.?

We have two companies(CNBM International & CNBM engineering Co.) with different approaches. We can supply not only the solar module but also Solar Cells, off grid solar system, even service with on grid plant.

4.Warranty policy?

Our product performance guarantees for 25 years

• 12 years guarantee for workmanship

• Timeliness of delivery

• Quality Products certified (TÜV, UL, CE, ISO)

5.Lead time?

In 3 days after purchasing, we will arrange the factory delivery ASAP. The specific time of receiving is related to the state and position of customers. Commonly 7 to 10 working days can be served.

Q: I want to know how you can store energy using a solar panel. The energy stored needs to be stored so that a light or laptop charger can plug in to it.: Batteries my man... but you will need a charge controller the silicon panel will produce dc and you will need an inverter for an ac light

Q: What are solar panels?: Solar okorder

Q: I am trying to built a circuit that will power two USB ports (both 5V and 0.5 amps) from the output of a solar panel that produces 20V at 0.2 amps. I have a voltage regulator that runs at 5v and 0.5 amps but I can't figure out the best way to boost the current up to 0.5 amps before I incorporate the voltage regulators.: The previous answer about wattage is correct, so this is your first problem. Try increasing the number of solar panels by connecting them in parallel. To answer your question about increasing current, a voltage regulator wastes energy to regulate voltage. You need somthing that is not so wasteful, and that is a DC-DC converter. You will need to buy a 20V-5V model. this will give you less voltage but more current than you origionally had with your solar panel. You can alter voltage and current capacity, but you cant increase power (watts) with a DC-DC converter.

Q: I want to add solar panels to my home. I was looking online and it seems there are so many different kinds! How does it hook up to the electrical grid? How much do I need for a 2000 sf home?: This is still not a trivial project, although it is getting easier. The usual way to do this is to contact professional installers for free quotes. In the process of getting the quote, you'll learn what considerations go into sizing a solar system. They'll look at your energy usage, and also whether your house has a good, clear, south-facing roof that doesn't get shaded during the day. They'll also look at your electrical panel to see whether they can hook right up, or additional work is needed. There are rumors of companies like Akeena planning to sell panel kits in Home Depot (in areas that Akeena does not directly serve). The idea would be that a pro installer would pick up the kit there, but a highly skilled homeowner might be able to make it work. A permit will probably be required by your jurisdiction, but that's no different than applying for any other construction. And you'll have to inform your power utility in advance, which may or may not be routine, depending on how often people connect solar in your area. If you want to see how we connected our system, a link is below. I did not really save money by doing it myself. That's because pro's can get better prices on the panels, which makes up for the labor cost.

Q: Can solar panels power an entire house?: Yes, solar panels can power an entire house. The number of panels required depends on the energy needs of the house and the amount of sunlight available in the area. However, with proper installation and integration of a solar panel system, it is possible to generate enough electricity to meet the needs of an entire house, including appliances, lighting, heating, and cooling systems.

Q: Can solar panels be installed on carports or other structures?: Yes, solar panels can be installed on carports or other structures. In fact, carports are a popular choice for solar panel installations as they provide an ideal location for capturing sunlight and also offer additional benefits such as shading for parked vehicles and protection from the elements. Installing solar panels on other structures like roofs or pergolas is also feasible, depending on the structural integrity and suitability of the location for harnessing solar energy.

Q: Can solar panels be installed on a building with historical significance?: Yes, solar panels can be installed on a building with historical significance. However, it is important to consider the potential impact on the building's aesthetics and historical value. Careful planning and consultation with preservation experts can help ensure that the installation is done in a way that minimizes any negative visual or structural impact on the building while still harnessing the benefits of solar energy.

Q: i am very new to the solar world and i need help with some stuff to understand what i need to do.what AH battery should i use? i am planning on getting a 2V deep cycle gel based battery but i want to get the most power for my system so should i use something like a few 00AH in a battery bank system or a bunch or 50 or so amp hour batteries in a bank. also what kind of power am i looking at for the best battery system. in other words what kind of basic appliances like lighting, laptop,space heaters etc can can i run on the selected battery system and for how long? any help would be highly appreciated.: This site has some good info and links to more info about renewable and alternative energy. Hope it helps you. Good luck.

Q: Can solar panels work during cloudy or rainy days?: Solar panels can still generate some electricity during cloudy or rainy days, although their efficiency may be reduced. The panels can still absorb and convert diffuse sunlight into electricity, albeit at a lower rate compared to sunny days.

Q: Can solar panels be installed on tile roofs?: Yes, solar panels can be installed on tile roofs. Specialized mounting systems are designed to secure the panels to the tile roof without damaging it, ensuring a safe and efficient installation.
