FAQ

We have organized several common questions for our clients,may 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)

Q:0W solar panel can use on what?
0w Solar Panel Kit
Q:Solar Panel Current=Battery Current+Load Current?
I am not sure about your question ? If your Q is, what is the solar panels current output, it is 8.73A regardless of the load. If the Q is, How much extra current is available in this circuit, the answer is 3.58A ( 8.73 - 4.32-.83= 3.58)
Q:What is maximum system voltage in solar panel?

Q:How can I make a sun tracker for a solar panel?
tbls0 has a good idea for the tracker, but let's take this one step farther. A clock motor large enough to move a solar panel, unless it is a very small one is going to be large, and expensive. Use the timer motor, as suggested, but attach a slotted disk to it, with a light source on one side, and a detector on the other side. As each slot comes up and allows light to pass through, this creates a one shot pulse which is used to cause a stepper motor to move position to keep the panel aimed at the sun. At the end of the panel travel for the end of the day, a switch could be set to close, bypassing the step control to put the motor into full constant speed reverse, this causing the panel to swing back to the morning position. The whole affair gets it's start up call by means of a light detector, similar to those used to turn lights off at sun up. The control would, of course be set to turn the system on to track the sun during the day. While some digital control is going to be needed, the system would not need a computer to run it.
Q:Can I hook up a Solar Panel to a car battery? Does it matter the kind of car battery?
Those answers are partly correct. You cannot recharge two 2 volt batteries in series with a photovoltaic panel with an open circuit voltage of 8 volts. You possibly over charged your 7.5 AH battery with a 00 watt photovoltaic panel, which can supply 8 amps to the battery with unusually bright sun light = fully charged in one hour. More likely you did not charge the battery for a month or more which killed it. Also discharging below 2.6 volts shortens the life of the battery, or short circuiting the terminals even briefly. Yes a deep cycle sealed lead acid battery rated 2 AH is likely the best unless you buy a 00 amp hour marine battery which weighs about 80 pounds and will take at least two days of bright Sun to fully charge.
Q:what materials would you use and how would you construct solar panels enough to run a household?
Silica based solar cells are not the kind of thing you whomp up in you basement. Here are a couple ideas for solar systems you can build and install yourself. Take a 4 x 8 sheet of /2 inch plywood. Frame sides with 2 x 4's. Screw tin cans in a staggered row (checker board) pattern inside frame. The more cans the more heat you get so place them nearly touching. Paint cans and entire assembly flat black. Cover top with glass, plexiglass (best) or heavy mill clear plastic (cheapest)Place on roof. Drill 3-4 inch holes in opposing sides. Run pipe or tubing into house. Attach to small low speed fan. The black paint will absorb sunlight and heat. The air moving through box will carry heat into house. It's a cheap efficient way to help heat your home. You can vary size and shape of box to fit your roof. If you use more than one box, hook them up in series. More boxes mean more surface area means more heat. To heat water. Take a steel tank. A car gas tank works well. It is galvanized so it won't rust, is cheap, and easily available at any auto salvage yard. But you will have to flush in throughly to remove gasoline odor. A steel 55 gallon drum is easier to work with but may cost more. Paint exterior of tank flat black. Weld/glue/clamp water pipes to tank. Place on ground in area that gets lots of sunlight. Attach water supply to tank and route discharge pipe to house or appliance. Black painted steel absorbs heat from sun light and heats water. In spring and fall you get warm to hot water. In summer you get scalding hot water and in winter you get cold to luke warm water. Both of these solar powered systems are seasonal and their output varies according to location and climate, but they are very inexpensive and easy to build and provide FREE heat and/or hot water for many years with little or no maintainence.
Q:Solar Panel Question...?
Nice enough idea you have there, but practical reality is waiting to bring you back to your senses. The appliances you want to operate take a lot of power. You would need an awful lot of solar cells or a very cumbersome windmill to provide sufficient energy for them. You will find that for a mobile kitchen, an ordinary generator running on gasoline or diesel will be much less expensive to buy and maintain, less trouble to haul around, and much easier to replace if necessary. Considering that propane will probably prove less expensive yet, go with that for as many appliances as possible.
Q:What capacity solar panel do I need to charge batteries with a total capacity of 25,000 mAhours in 8 hours?
WIRE THEM IN PARALLEL BUT MUST VIA ONE BLOCKING DIOED FOR EACH 4V BATTERY BANK ( LIGHT) BETWEEN SOLAR PANEL OUTPUT TO EACH BATTERY BANK. DIODE USES LIKE N5404 THAT CAN HANDLE 3A OR HIGHER IS BETTER. TOTAL AH = 9.8 AH FROM ALL 4 LIGHTS. NOT 25AH FROM YOUR MISTAKE RATE. TO CHARGE THEM FULLY IN 8 HOURS, CHARGING CURRENT AT LEAST .3A BUY SOLAR PANEL HAS OUTPUT 6V 2A ( OR 0W ) IS GOOD ENOUGH.
Q:question about GE solar panels?
Retail, between $5 to $6 /watt.
Q:hi i am asking about the life of solar panels?
They degrade over time, losing efficiency. They're generally good for several decades.
