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:Reasons for installing solar panels in a school?
You have to approach it as an investment. Ignoring the cost of an inverter for net metering, if we consider a 500 W panel installed for $0 a watt which is $5,000 and consider an average of 8 hours of usable sunlight per day, and at a rate of $0.0 per kWh (schools probably get $0.03 per kWh) then the panel would be saving $2.7 per month in electricity. Considering that the panel has an expected lifespan of 20 years, that would give you an internal rate of return such that the monthly rate satisfies the equation: $5,000 = $2.7 * ( ( - / R^24 ) / ( - / R ) - ) By binary method we get R = 0.99588342. Taking this to the 2th power to annualize it we get Ra = 0.9570 which means that we are getting an annual return of -4.83% per annum so investing in the solar panel is the same as making an investment at an interest rate of -4.83% per year. True interest rates are low and you only get about .3% per annum by putting money in a CD but that still beats investing in solar panels which gives you a negative return on your money. Solar panels need to get a lot better before they are a good investment.
Q:How much does 000 square feet of solar panels cost?
My Father-in-Law had around 300sqft of solar panels installed for the equivalent of around £3000 or $5000. These were just the cheap and relatively inefficient black plastic tubes that were installed on his roof. This was in South Africa where the labour rates are quite cheap. The system works okay and heats a 40ft x 20ft outdoor pool to over 30C in the height of summer. Rather than a pool heater, I think it might be good to look at an air source heat pump to help heat the water in Autumn/Winter when you don't get enough sun to heat the pool. These will be expensive (over $5000), but they will use less than 30% of the electricity of a standard electric water heater. Just the solar panels could cost you $5-20K including fitting.
Q:How much electrical energy is generated from one acre of solar panels?
Above the atmosphere, total solar flux is about 365 Watts per square meter. After passing through the atmosphere, the rule of thumb is about 000 Watts per square meter if the Sun is directly overhead. Solar panels are far from 00% efficient, though ... most silicon-based cells run about 20% efficiency. Which leaves you with roughly 200 Watts per square meter. One acre is 4046 square meters, which means that if you had an entire acre of silicon solar panels, they could generate a theoretical 800 kilowatts on a sunny day at noon. With the Sun 30° above the horizon, you could expect a 30% drop in power, declining to zero at sunrise and sunset. And that's assuming zero cloud cover, which is also an unreachable ideal. To give you an idea of scale, an average American home uses or 2 kilowatts. A large coal or nuclear power plant generates about a million kilowatts.
Q:Does a solar panel work on a cloudy day or a rainy day?
depending whether the solar array is back to grid or stand alone. Back to grid refers to the array being connect through the inverter to the main electricity supply grid. So when you are producing electricity from the solar array it feeds back into the main grid. Now if you are using more electricity than your array is producing then none will feed into the grid. The stand alone systems require batteries, which are charged from the electricity produced by the solar array. Solar arrays produce electricity on cloudy and rainy days but at a greatly reduced rate ; therefore little to no usable electricity is produced. Stand alone systems require batteries to store the electricity for use at night time and other times when the array is not producing . The back to grid systems require little to no maintenance as the electricity produced is fed back into the electricity network and stored there. Your meter is replaced with a dual meter . It reads your usage and your production. If in Australia you will get paid for the electricity you feed back into the grid. hope this helps.
Q:solar panels on projectors?
Solar panels put out DC voltage, like a battery. The projectors that plug into the wall require AC voltage. Unless you got a travel projector that plugs into a cigarette lighter (does that exist?), you would need to convert the DC power from the solar panel to AC for the projector with an inverter. And if you want to use it when the sun isn't shining, you'd need batteries to store the power.
Q:How many solar panels would I need to power my washer machine?
Solar panels produce power in proportion to the amount of sun light and inverse proportion to the temperature. To use solar power you will need in addition to the panels a bank of batteries a charge controller and an inverter to convert to 20v. The panel(s) will only be used to recharge the batteries and the batteries connected to the inverter is what is going to run your washing machine. You therefore need to know how long is the machine going to run, how often and how much charging can you expect to get from each panel in order to figure out how many panels you will need and how many batteries. If you do only one load very infrequenly, you will be able to use a smaller battery bank and charge at a lower rate.
Q:Maintenance of Solar Panel?
panels need full sun. any shade reduces out put. leaves left on them will cause the individual cells burn out. they nneed adjusting every season, an washed with a soft cloth once a year.
Q:Has anyone gotten their solar panel rebates in Florida?
In case you hadn't heard the state is broke.
Q:Solar panel battery charging?
it depends how big the panel is. a small trickle charger (like a 2W panel with built-in diode), just connect + to + and - to - (parallel) to trickle charge the battery. The diode will keep the batter from discharging through the panel when there is insufficient sunlight. for a large panel (like a 220W 24v panel), you best go through a charge controller. the charge controller has 2 leads for the solar panel input, 2 leads for the battery connection and 2 leads for the 2v load. just follow the instructions to connect the panel and battery to the controller, and MAKE SURE YOU USE THE REQUIRED FUSES. very straightforward stuff -- just RTFM
Q:Shouldn't 0bama increase our tax benefits for solar panels so we can buy more Chinese products?
China is also the world leader in using solar panels. Most solar panels in the US are not from China. There are several companies here in the US that make solar panels, and many states do increase the tax rebate for buying local products. Most flat plate water heating panels installed in the USA are made in the USA. Wouldn't it be nice to get people to buy more sustainable energy products and increase manufacturing jobs in the US, while actually improving the air quality and reducing our dependence on foreign oil? Oh, and perhaps we could get the money by cutting the amount of taxpayer funds subsidizing the oil and coal industries?
