 FAQ

Q 1. what's the payment term?  

A. We accept TT,30% deposit and 70% balance agaisnt copy of BL

Q 2. how's the delivery time ?

A. usually it will take about 25 days for production

Q 3. tell me the standard of package?

A. For the small capacity, it use carton, but for big capacity, we will use strong wooden case for protection

Q 4. what kind of material of transformer?

A. we have two types, one 100% copper and the other is copper with aluminum.It depends on your requirment. In fact,those two have no difference if normal work well. Only except the longlife. Copper is better and also higer price.

Q:Could solar panels contribute to global warming?
I highly doubt it because they don't trap heat like carbon gas does in the atmosphere. Fossil fuels are literally destroying this planet and could eventually be it's demise it we don't accelerate it's elimination. If we could make the clock turn back to the early 20th century and focused on harnessing the sun and wind instead of burning fossil fuel as a means of transport and energy, we wouldn't even be talking about global warming or air pollutants that contribute to global health every year. The only thing the black panels to is create a darker surface but not much different than natural colors like dark dirt, dark green grass etc.
Q:How powerful are solar panels?
if you are talking electrical solar panels, they are rated in watts they generate in full sun. usually these panels are used in tandem with batteries, so they charge up during the day and the batteries hold a reserve of power for later use. If you figure 8 hours of useful sunlight per day, then a 40 watt panel will light a 40 watt bulb for 8 hours. you can also measure capacity in watt-hours. this would be 40x8 = 320 watt-hours. the general method is to determine how much electricity demand you have over a 24 hour period to get the total watt-hours. then divide that by the watt-hour capacity of one panel to get the number of panels needed.
Q:How much for a 8kwh solar panel system?
Figure 8 hours of sun per day, so 8 kW-hr is a rate of kW, which is a medium sized panel, probably not enough to operate your house totally, unless you have a very small unit. Averaged over 24 hours, that is power at a rate of only 300 watts, enough for a TV. Average US home use is .2 kW, which over 24 hours is 29 kW-hr, plus you need extra for cloudy days, peak demands, and to charge batteries. You have to decide off-grid or on-grid, and if you want to (and are allowed to) sell excess power to the power company. Off gird, the cost of batteries and charge controller are a large part of the cost. On-grid, you have to purchase equipment approved by the power company to match your power with the grid. Panels will cost about $3 per watt, so for 000 watts that is $3000. Double that for installation, then add in cost of charge controller, inverter, batteries, etc. The last items depend on your alternatives, see paragraph above. .
Q:Which stores can you buy solar panels at?
This one.
Q:help understanding solar panel stuff?
Any fan you find in a store is going to expect AC, not DC, which is what solar panels produce. An inverter changes DC to AC. You'll probably want a deep cycle car battery to smooth out overages and underages. Any fan will tell you how many watts it uses. Panels should (i haven't looked) tell you how many watts they produce. Just off hand, I'd guess you're looking at a 2'x4' panel. Considering how much you'll be paying for the rest of the stuff, a good 00' cord is appropriate,. Last, it's worth the experience, but you'll never recover the cost of everything that you'll have to buy. Have fun.
Q:List of new solar panel manufactures?
damn I wish i could help you but I think the United States is too cool for solar I would move to Italy or Germany or China or India if you want a good solar job those guys know how to see into the future of energy
Q:How do you store energy using a solar panel?
probably a deep discharge lead calcium batteries, with a switching regulator cycloconverter or cycloinverter output to match the current and voltage requirements of the operated device.
Q:Can one benefit from solar panels?
In theory, yes. But the fact that nobody is doing it implies there is something wrong with the idea. Solar panels are not exactly new.
Q:does vibration affect solar panels?
probably not much. If you had it at an optimal angle to the sun and it vibrated out of that position then you could be loosing some efficiency.
Q:How much energy does this particular solar panel produce?
To calculate an estimate of your power usage, follow the first link below. Although you can have whatever sized system you want (at a cost) those on solar power generally keep their power usage down by cooking on gas, not using an electric kettle, using low energy light bulbs. Powering AC would up your power requirements considerably. We run a medium sized house on 860 watts of panels in southern Spain (plenty of sunshine). That includes the washing machine, pool, and running two laptops and wireless network all day,and a ceiling fan on summer nights. Hower we cook on gas, would not consider AC, and the fridge runs on gas (though if the fridge had to be replaced I would buy electric and add an extra pv panel).
