FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: What is a solar PV module?

A: A solar PV module consists of many solar cells that are connected together (typically in series) and packaged in a frame (typically made of aluminum).

Q3: What are the advantages and disadvantages of monocrystalline solar PV modules?

A: Monocrystalline solar PV modules are the most efficient type of solar PV modules, with the exception of CdTe thin film solar PV modules. As a result, monocrystalline solar PV modules are more expensive when compared to almost all other types of solar PV modules.

Q:Solar panels.......Earning potential.?
it depends on your solar panel, but you can sure supply most if all of your electronics and electric stuff in your house on a sunny day. If you want to know exactly how much power it supplies and how much $$ you can save you simply have to calculate how much power your home consumes per day/month. I know of people totally reliable on solar power for their home and I too will put solar panels on my home one day.
Q:harbor freight solar panels ?
I bought my first set 8 years age and the 45 watt set finally gave up the ghost last week. I have another 45 watt set 3 years old and has maintained 4 2 v deep cell batteries at 3.5 to 3.8 volts for the last 3 years. I have them on my cabin and use them mainly for lights and TV. but with my 2000-4000 watt inverter runs the microwave nicely.
Q:solar panels for my home.?
Check your electric bill, and see how many kilo watt hours you have been using for the last year. That will give you a clue as to how many panels you will need in the array,and how many batteries you will need, what size inverter is needed plus would you want a true sine wave or modified.And that's just for starters. But of course you might get a break from your electric Co.(Rebate) also from your state,and possibly something from the Feds. I have installed on the travel trailer a 25 watt panel($850) a 22amp.charge controller ($45) a pair of Trojan 425 watt 6 volt batteries ($300 each) and a 2000 watt inverter modified sine wave ($2000).The only thing I can not run with this set up is the A/C which requires 3000 watts of power. So as you can see your project could get very expensive. I hope this sheds enough light on the subject for you.
Q:How Do solar panels work?
Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .
Q:Any drawbacks for solar panels?
There okorder.com/... ). These systems provide relatively high efficiency, since they don't convert sunlight to electricity, and they can be used to supplement or replace energy used for space and hot water heating - some of the largest residential uses of energy. Like any other appliance or household system, solar panels used to collect heat will require periodic maintenance. Hope this helps.
Q:Amount of solar panels needed to run a/c and pool pump?
Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.
Q:solar panel, dc light help?
3 w for 2 hours/night is 36 watt hours. You'll get about 500 watt hours/day from your panel on the average, which for a 2 volt battery is about 40 ampere hours. You can get an 80 amp-hour sealed gel cell battery to charge with this panel (with a suitable charge controller). You want to size your lights so the battery can provide three days of light without discharging it more than 50%, so that's abnout 600 watt-hours/3/36 = about 4 orf 5 lights. Cost for this system woulkd be over $500. The advantage of the self contained light is they use a lithium or nickel battery rather than a lead acid, so it can run totally dead without damage (unmlike a sealed lead-acid battery). That would be a far cheaper way to go. DK

Q:solar panel inverters?
Investors in this ground-breaking technology include Rockport Capital Partners, Third Point Ventures and Applied Ventures, the venture capital arm of solar equipment manufacturer Applied Materials. Enphase Energy's CEO Paul Nahi said the company raised money earlier than expected due to strong demand for its microinverters. So what are these microinverters? The Enphase Micro-inverter shifts DC to AC conversion from a large, centralized inverter to a compact unit attached directly to each solar module in the power system. Distributing the conversion process to each module makes the entire solar power system more productive, reliable, and smarter than traditional solar panel inverter systems. Usually, one single inverter is dedicated to a rooftop array of panels for a homeowner. Enphase Energy, however, have built a DC-to-AC inverter that is placed on each single panel. This makes it more reliable than a centralized inverter and more efficient, so panels can generate more electricity, Nahi said. Enphase has already started shipping its microinverters and has tied up deals with several panel distributors and installers. The future of inverters? Enphase Energy has been able to improve the DC-to-AC conversion efficiency to around 95%. Because of this, Nahi predicted more companies will turn to decentralized inverters. There's been very little question on the benefits of microinverters, but people didn't think it was possible to get the efficiency levels required, he said. Now it seems that they have.

Q:can a small solar panel be charged with lamps?
That would depend on the frequency that the solar panel accepts and the frequency of light that your lamp gives out. It may or may not work. The sun gives out a much broader spectrum of light, which is why solar panels are much more effective in sunlight. I have seen solar panels charged by lamps, but it usually doesn't work that well and I have never seen it work with fluorescent lighting.
