FAQ

We have organized several common questions for our clientsmay help you sincerely

①What price for each watt?

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

②What is your size for each module? Can you tell me the Parameter of your module?

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

③Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?

Yes, we can, we have two companies for solar region, one is CNBM International, the other is CNBM engineering Co.

We can provide you not only the solar module but also the off grid solar system, we can also provide you service with on grid plant.

④What is your warranty system?

 Our product  performance guarantees for 25 years

• 12 years guarantee for workmanship

• Timeliness of delivery

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

⑤How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

⑥ Can you do OEM for us?

Yes, we can.

⑦How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served.

 

Q: Does the new horizons has a solar panel for it power resources instead using nuclear generator?
It uses the nuclear decay of plutonium in a 'Radioisotope Thermoelectric Generator, or RTG. The heat of plutonium decay is captured and converted to electricity. Pioneers 0 and , Curiosity on Mars, and other deep-space probes use this, as the sun's light is too dim to use solar panels.
Q: How do solar panels affect the electrical grid?
Solar panels affect the electrical grid by supplying clean and renewable energy. When solar panels generate excess electricity, it can be fed back into the grid, reducing the overall demand for fossil fuel-based power generation. This helps to stabilize the grid and reduce carbon emissions. However, the intermittent nature of solar power can create challenges for grid operators in managing variations in supply and demand.
Q: Online stores selling solar photo-voltaic generation kits gives specs indicating the power generation capability of the system. For example, Solar World Grid-Tie Solar Electric System with 245W Panels PV Powered PVP2000 Inverter, .2 to 2.4 kW. This seems to indicate that the system can generate .2 to 2.4 kW. Is that per day? Per month? I'm trying to calculate the return on investment, but can't because I don't know how much power a system such as this will generate in a month.
That would have to be in that instant of time or they would say kilo watt hours or KWH for short. But being the sun doesn't shine at the same intensity over any given hour you couldn't say a solar panel rated at 2.4KW would produce 2.4KWH of electric in a given hour. The power produced would have to vary as clouds passed over head. The power would also be reduced on days of heavy overcast or rain/ snow.
Q: i hav e a project for school we need to calculate cost to buy and install solar panels in our school
to okorder / you should really be able make report with this informatin. So for your school it would cost millions, you need to figure out how many kilowatts your school use, then use the information above to calculate how large of system would be required you will be very impressive and the most informed person in your school.
Q: Exactly How much power will this kit produce? for example. Will it only be able to power the 2 light throughout an entire day or would it be able to power a couple TV's with a couple lights. Or a Refrigerator? washer dryer? I'm just wondering exactly what it will be able to do and if it's worth paying $200 for if it'll only power two lights. Don't get me wrong, That's great and will make a difference but i'm looking for something that will make a little bit of a bigger difference. Would the 80 watt monocrystalline solar panel be much better? if so, what would it be able to power? double?
Yes, 80 watts will be nearly twice as useful as 45 watts - but 80 is still a small number. Solar panel systems need an inverter and there's a slight energy loss at the inverter. And, if you want to use the day's energy at night, you'll need a battery or two. And every time you move energy into or out of a battery, you lose a little of the energy. All this is to say that you need to sum up the wattage of your appliances and add a fudge factor to accommodate for the losses. I looked at the kit and was moderately impressed. $200/45=$4.44/watt; that's a reasonable price but the links I left below talk of prices as low as $2.58/watt. Also the Harbor Freight kit doesn't contain an 'inverter' which you would have to buy. Also the wattage advertised for any solar panel assumes the thing is clean and pointed right at the sun on a clear day.
Q: I have a home made 24 volt electric cart. It is powered by two 2Volt deep cycle batteries. Since the motor runs on 24 volts the batteries are wired in series to produce the 24 volts. I only have a 2 volt battery charger, but I also have two 2 volt solar panels. It is a pain having to unhook wires, rewire it, or charge them one at the time.HERE IS THE QUESTION REALLY... Can I wire the two 2 volt solar panels together in series (ie: negative to positive) then connect it to the existing 24 volt system and have it charge the batteries fine. I know basic wiring, but I know nearly nothing about solar panels, will it work fine? will it cause them to break? or short out?(additional info, the solar panels are only rated at 5 amps so it will not overcharge the batteries or anything)
Wiring the panels in series should be ok as long as they are exactly the same. Different impedance's could damage the panels. Remember that Voltages and Amperage's are indirectly proportional meaning that if you series your panels your voltage will rise but the amperage will be reduced.
Q: can solar panels be on houses? malls?stores? WHAT ABOUT TRAINS?
Hope This Helps!:)
Q: What is the difference between on-grid and off-grid solar systems?
The main difference between on-grid and off-grid solar systems lies in their connection to the traditional electrical grid. On-grid solar systems are connected to the grid, allowing them to both generate and consume electricity from the grid when needed. They can also feed excess electricity back into the grid, earning credits or compensation through net metering. In contrast, off-grid solar systems are not connected to the grid and operate independently, relying solely on solar energy to generate and store electricity in batteries for use when the sun is not shining. Off-grid systems are typically used in remote areas where grid connection is not available or for those seeking complete energy independence.
Q: How much space is required for installing solar panels?
The amount of space required for installing solar panels varies depending on the size and type of the panels. On average, a residential solar panel system typically requires around 100-400 square feet of roof space per kilowatt of installed capacity.
Q: China is the world's biggest producer of solar panels
America should be making the panels and imposing large tariffs on any country trying to import theirs here.
