FAQ

We have organized several common questions for our clients,may help you sincerely:

1.What price for each watt?

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

2.Can 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.

Q:Mono-crystalline or poly-crystalline solar panel?
All solar photovoltaics drop in efficiencies with higher temperatures but it isn't the 45+ C you have to worry about but rather the heat from the sunlight striking the panels. There are hybrid systems which passes water in pipes attached to the back of the solar panels to cool the panels and preheat the water for solar thermal collectors. The difference between mono-crystalline and poly-crystalline are that mono-crystalline are more efficient and more costly to make.
Q:how many 45 watt solar panels would I need?
Lets say, for a simple approximation, that the 45 watt panel produces 45 watts /3 of the time and nothing the rest of the time. Each day, this will produce 8 hours times 45 watts = 360 watt hours. Also assume the battery charge controller and inverter waste half of that power, leaving 80 watt hours per day. If you use compact fluorescent lamps, that would allow you to burn 80 watts worth for an hour every day, or 90 watts for 2 hours, etc. That is a lot of light for a shed. You might consider using much less efficient tungsten filament lamps, but eliminate the inverter and choose low voltage (automotive) lamps that can run directly across the battery and lower the total cost, but give you only about half the light times time. The main advantage of the inverter might be that it would allow you to use small power tools or appliances in the shed. -- Regards, John Popelish
Q:Can a solar panel work with an inverter?
There could be a couple of reasons why it isn't working. First, 2V panels actually put out a considerably higher voltage because it is presumed that they will be used to charge a 2Vdc battery. That requires applying a voltage greater than 2Vdc, and usually there is a solar controller that regulates the solar power to the battery. It also has a voltage drop. Look at the first reference reference, and you will see these values for a particular panel: Voc: 2.6V (open circuit voltage) Vmp: 7.2V (voltage at maximum power point) Voc is the voltage the panel produces under standard sunlight and temperature conditions (25°C), with no load applied. As load is applied, the voltage drops (see reference 2). Power is the product of current times voltage, so at one set of conditions (namely at Vmp) maximum power is available from the panel. Your inverter might not be working for either of two reasons: ) it has input protection circuitry that locks out operation when it senses an overvoltage, as in the 2.6V open circuit voltage, or 2) the panel does not produce enough current and the voltage from the panel collapses under excessive load. For example, if you load your inverter to 20W, then nominally the 2VDC input to the inverter must supply 20W/2V/eff = 0A/eff Assuming the inverter has an efficiency of 80%, the input current required is: 0A/.8 = 2.5A A solar panel operating at maximum power would need a rating of about: 2.5A x 7.2V = 25W Is your panel that big? The other option, as mentioned by others, is to charge a battery that runs the inverter. Other nuances: Voc increases as temperature decreases. Sunlight intensity varies (obviously), so the panel may produce less than rated power. The power specifications often are printed on the back side of the panel.
Q:How do you make solar panels?
It's possible to put together pre-made solar cells into your own panels, but the result will be far less durable, and more costly than simply buying commercial panels. You may encounter some websites offering to sell you information on how you can power your home cheaply with homemade panels. Every one of those I've seen is a scam. Save your money. Do you need a lot of panels to make electricity? To make a system that is worth it generally takes at least a dozen panels, although I'm sure exceptions exist. Also, it generally needs a professional install to meet legal requirements, although a few skilled homeowners do manage to do their own.
Q:how do solar panels work?
Sunlight hits the solar panel, and DC power is generated. By the power is not stable. It becomes stronger or weaker according to the strength of sunlight.
Q:Adding Solar Panels to my home in Portland, Oregon?
I wish it was that easy! Maybe it will be soon. But at this time, no, there isn't. And if you have a solar collection system, you have to have a way to store the energy when you're producing more than what you are currently using. That usually involves an expensive battery array. But it's necessary. The power coming directly from the solar panels will be erratic and sending it to the battery array for storage and then use allows for the home to draw a consistent level of power. And this battery system also allows for storage of electricity for use when the sun isn't shining like at night. The system should be set up to use your power first, then go to the grid. It should also allow for distribution to the grid when your system has stored all the power it can and that's when your meter will run backwards and the power company will be paying you! There are a lot of federal and state income tax rebates for alternative energy installation costs. Check out what Oregon might toss into the package along with the Feds and see where you might come out.
Q:How to make 2V 4.5A solar panel from solar cells?
To increase current, you connect the cells in parallel. But I think you really mean you need 4.5 watts rather than 4.5 amps of current. For an RC car, 4.5 amps would be huge, literally a regular car battery. So I think you mean you need a 2v, 4.5w panel. That would make more sense for an RC car battery. I went on OKorder and bought a 2v, 5 watt panel for about $30.
Q:Does anyone know a company that will make custom solar panels?

Q:45 Watt Solar Panel Kit Harbor Freight?
This Site Might Help You. RE: 45 Watt Solar Panel Kit Harbor Freight? 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...
Q:Can I made my own solar panel?
I don't think it would be very easy to do with household stuff, or even with anything you can find in stores. All I can tell you is that typical electronics LED lights tend to create current when they have light shining on them, but you would need millions for them to be any use.
