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:Do solar panels require a backup generator?
No, solar panels do not require a backup generator as they generate electricity directly from sunlight, eliminating the need for external power sources.
Q:what do I need to do to disconnect a solar panel from a battery to protect the panel?
Know that solar panels almost always incorporate a blocking diode to prevent a battery from back-feeding through an un-illuminated panel. Know that solar panels are usually connected to a battery via an electronic switching charge controller, not directly connected. Know that when a solar panel is open-circuited (disconnected from everything) it's terminal voltage will rise to almost twice it's nominal voltage. (22V is common for a 2V panel), unless it is stored in total darkness.
Q:How often do solar panels need to be replaced or repaired roughly? Is it costly to do so?
I'm okorder /... . That means that not only do they guarantee the panel won't completely die, they guarantee that it will deliver a certain amount of power. That suggests that manufacturers expect most panels to last longer than 25 years. Our panels have been up a little over 5 years - no trouble yet. In a dirty location, or where the panels are mounted flat, occasional cleaning may be required. In many place, the morning dew and slant of the panels is enough to keep them clean. In my limited experiments with our panels, I saw little difference in power production between a panel that appeared dingy to the eye, and one that was just cleaned. There is a component called an inverter used in most solar power systems. That generally has a warranty of 0 years, so expect it to break after 5, to be replaced at a cost of a few thousand dollars. Or maybe repaired for less. The kind of solar power popularly installed today does not use batteries. Batteries are generally only for remote installations that did not have grid power when the solar was first put up.
Q:my dad met a guy representive for a solar panel company at a swapmeet Scam?
Hard to say. Solar panels are becoming more common these days. May want to ask if the vendor is licensed and bonded contractor (if he's doing installation as well as panel sales). Find out the name of the equipment that this guy is selling (panels and other hardware) and do a search. For that matter, get the guys name and do a search on it to see he pops up elsewhere.
Q:Can solar panels be used for powering a concert venue or entertainment center?
Yes, solar panels can be used to power a concert venue or entertainment center. Solar energy can be harnessed through panels and converted into electricity, which can then be used to power various aspects of the venue, such as lighting, sound systems, and equipment. By utilizing solar panels, these venues can reduce their carbon footprint and potentially save on energy costs in the long run.
Q:Do LED lamps ever go bad?What's the life expectancy of solar panels?
ED stands for light emitting diode, an electronic device which turns electric power into light with nearly perfect efficiency. When used in flashlight or othe battery powered lights, they will provide equal amounts of light for 00 times as long as ordinary incandescent light bulbs. Because of there very low power usage, led light are ideal for solar powered lighting systems. They are now made in every form and size, for DC or AC power, for homes, automobiles and outdoor lighting. Although they cost more, the savings from 20 year life expectancy and % power use mean savings of 95% over several years. sunsourcepower
Q:Can solar panels be installed on a south-facing wall?
Yes, solar panels can be installed on a south-facing wall. In fact, a south-facing wall is often the most ideal location for solar panel installation as it receives the most sunlight throughout the day.
Q:Can solar panels be used in apartments or condominiums?
Yes, solar panels can be used in apartments or condominiums. However, the installation process may vary depending on the specific building structure and ownership arrangements. In some cases, individual units can have their own solar panels installed, while in others, a shared or community solar system may be implemented to provide renewable energy to the entire building.
Q:Hi. I have been looking into getting solar panals but I only want them for one room. See, we're expanding the house by adding a basement, the basement isn't going to be that big but we wanted to have solar energy for the basement only. Could anyone give me a rough estimate on the cost of solar panals for my basement?
If you're really planning on solar energy, don't waste it on your own consumption. The Hydro company pays you for the energy you put back into the grid....the strange thing is, you buy the power back for less than you sold it, so you actually profit on the power you make! look into this. I wired a nice house for a doctor, and although I didnt supply the solar system, I learned of this concept there. The guy who installed her system charged her around $40,000.00 and the system would never be able to run any large portion of their home. They, of course sold the energy to the utility.
Q:I'm curious to know if the small solar panels on a calculator (ie TI-32) could produce a voltage similar to what is used in a single-use (disposable) camera, approximately 4V.
