INTRODUCTION
This installation Manual contains essential information for the electrical and mechanical installation that your must know before installing CUSTOMER PV modules. This also contains safety information you need to be familiar with .All the information described in this manual are the intellectual property of CNBM and based on the technologies and experiences that have been acquired and accumulated in the long history of CUSTOMER. This document does not constitute a warranty, expressed or implied.
COMPONENTS
WORK PRINCIPLE
WIRING
To ensure proper system operation to maintain your warranty, observe the correct cable connection polarity(Figures 1&2) when connecting the modules to a battery or to other modules. If not connected correctly, the bypass diode could be destroyed.
PV modules can be wired in series to increase voltage. Connect wires from the positive terminal of one module to the negative of the next module. Figure shows modules connected in series .
GROUDING
All PV models must be grounded by electrical connection of the module frames to ground. Please be careful in arranging the system ground so that the removal of one module from the circuit will not interrupt the grounding of any other modules.
The modules should be grounded to the same electrical point as described below.
Each PV module has a hole on the side frame of either a bolt, nut and washer grounding the module to the frame, a ground lug fastened by bolt or screw, or appropriate screw(hardware not provided).An example of acceptable ground connection using a bolt, nut and washer retaining a ground lug is shown in figure 3,in a connection of this type, the hardware(such as a toothed locked washer/star washer) must score the frame surface to make positive electrical contact with the frame. The ground wire must be considered within the requirement of local and regulation at the site of installation.
- Q:Are solar Panels worth it, Do they really quot;save moneyon electricity?
- “Where you have good (sunlight) and access to financing and a combination of federal and state incentives, you have a number of markets around the country that are very vibrant, and it’s very cost-effective with financial paybacks in the order of five and 0 years,” said Robert Margolis, a senior energy analyst at National Renewable Energy Laboratory (NREL).
- Q:Hello Yahoo, I am doing another one of my wacky inventions however I need something that will give me 2V of power!I don't want to connect loads of AA batteries into a battery holder as this shall run out quickly and become expensive in the long run, I don't want to carry around a big car battery either.I have been searching around on OKorder .uk and found some Solar-Powered 2V Trickle Chargers. These say they shall work on cloudy days (which is perfect as the majority of the time that is all we get!) but could I use it as an independent power source?If I attached the thing I want to run to the solar panel will it supply it with 2V of power?
- If you want to run something from a solar panel, you should remember that the power from the panel is only available when there is reasonable sunshine on the panel. Usually the solar panels are used with solar regulators in order to charge batteries. These batteries are used as energy storage for when the sun is not shining. Now, this does not mean that you cannot drive instruments directly from the solar panel and regulator. To do this, you will need a panel that has sufficient power to drive your instrument. An example is the solar powered garden or fountain pumps. I have driven 2V computer fans directly from the small solar panels - useful for cooling of things such as pool pump housings. The solar regulator is used to convert the solar panel output to a 3.5V output in order to charge lead acid batteries. I have used MPPT regulators (maximum power point tracking) which is more efficient than the standard solar regulator. If you don't use these regulators you may find the solar panel producing up to 7-9V in good sunshine which is not good for your instruments that are expecting 2-3V. Hence the answer to your question is that you will need to have a battery being charged to get useful power from the solar panels via a solar regulator.
- Q:I'm doing a science fair experiment with a tiny two-inch solar panel that only gives off like .5 volts of energy, but I need to know how many volts an average sized solar panel (like one you'd get to run your house) would produce. And how many panels do people usually get?
- You should read up on the different electrical units. You say .5 volts of energy, but this makes little sense. Energy is measured in Joules. Power in Watts. Solar panels will produce different voltages and currents, depending on the amount and angle of sunlight hitting them. Power = volts * amps. Before installing solar panels a home owner should do an energy audit to find out how much power they currently use - and how much that could be reduced with some easy changes. Solar panels are expensive, so it makes sense to reduce the amount that you need to install. In some places you can sell extra power back to your utility - so having extra panels might give you some small amount of money back - but this is rarely enough to justify the cost of the extra panels. I put 28 panels on my house (see picture in source URL). My utility has tiered pricing for electricity (first few kWh each month are cheap, but price for extra ones goes up in stages). My panels keep me from having to pay the higher rates.
- Q:How much energy can solar panels generate?
- The amount of energy solar panels can generate depends on various factors such as the size and efficiency of the panels, the location and orientation of the installation, and the amount of sunlight available. On average, a typical solar panel can generate about 250 to 400 watts per hour. However, larger solar installations or those with higher efficiency panels can generate several kilowatts or even megawatts of energy, which is enough to power homes, businesses, or even entire cities.
- Q:Properties of solar panel?I know this is too general,but i am to write a report on the materials used to make solar panels,and i am to include the physical, mechanical ,and chemical properties of the materials.It's just too general,such that i am lost.There are so many types of solar panels.So i hope some experts on this subject can give me a general guide lines ,maybe the tensile strength ?as much as you can please.
- Solar power Power Can Help Preserve You Money The cost of power is going up, and will only keep going up. Reaction Solar power Power Systems will help you save a large number of kWh each season by utilizing screen technology. Power created by your program are kilowatts you don't need to pay for! Every electricity program will make a number of Small-scale Technology Accreditations (STCs) upon purchase based on the size of the program and the location where it will be set up. These STCs have a market value and can be exchanged and marketed just like stocks. Power created by your solar PV program can be marketed to the lines for a top quality cost via Feed-in charges. These feed-in charges are different in every state, but the primary idea is te same, to compensate entrepreneurs of small-scale power creation. You are eligible to sell some or all of the ability you produce for more than you would normally pay for it. Would you like to decrease costs with solar power? Contact Reaction and get it done these days. Solar Power Can Help Preserve The Environment click to enlarge Producing usable direct sunlight generates no dangerous pollutants. Every season coal-fired power vegetation belch a large number of loads of as well as contamination into the weather so we can run our refigerators, toaster ovens, and have hot bathrooms. Taking your power form your own ceiling means you are no longer leading to that contamination. In fact, power companies will be paying you for electricity! Help Sydney accomplish its 5% green energy focus on by 2020 and international objectives of 20%, by changing to solar power and decreasing your own effect on international warming. Compared with other small-scale turbines, solar power is completely quiet. Turn the team radiation into power without making a audio and decrease environmental disturbance.
- Q:I have a solar panel 7.5V .25W 50mah, connect 2 in parallel to power a RC boat. The boat use to run on 6cell battery pack - 7.2V 800Mah.The dc motor requirement based on the provided battery pack, i assume would be 7.2V and rated at (7.2V * .8Amp) = 2.96 Watt.Would two of my solar panels run this DC motor ?are my calculations or understanding correct ?do lend a hand dear ''world''
- solar cells are not rated in mah, they are rated in ma or amps. I'll assume this one is 50mA. Two in parallel will give you 300mA, so that will charge a 800mA-hr battery in 800/300 = 3 hours. Theoretically, in bright sunlight if the array is exactly at right angles to the sun's rays. The problem is, depending on the type of cells, the battery pack will need 8 volts or so to charge, and your solar cells won't deliver that. If the sun is at an angle, you may get only 3-5 volts. so you have to put them in series, so you will get only 50mA out of them, which will charge the battery in 6 hours of bright sunlight. Would two of my solar panels run this DC motor ? If the motor is .8 amps, you need the battery, the arrays are not near enough. Or are you attempting to replace the battery pack with the solar array? Your english makes that difficult to understand. If so, put them in parallel to get the 300mA, but that would run the .8 amp motor very slowly. If you had 2 of the solar panels, it might run at close to full speed if the sun is bright and shining directly on all the panels. But where did you get the .8 amps for the motor? The 800Mah rating of the battery has ZERO to do with the motor current. So the answer above is based on your number, which I suspect is totally wrong. .
- Q:Any recommendations for companies? Any things to look out for?
- It strongly depends on where you live. In California or Hawaii, for example, solar can be cheaper than the power company, even without subsidies. Any incentives you get just make it better. Whatever you do, like any construction project, get 3 bids from different companies. If there are not 3 companies in your area, you are probably in a poor location for solar. Avoid any company that does a hard sell and tries to get you to commit immediately, or makes you uncomfortable in any way.
- Q:What is the impact of bird droppings on solar panels?
- Bird droppings can have a negative impact on solar panels as they can reduce the efficiency of the panels by blocking sunlight and reducing the amount of energy they can generate. Additionally, the acidic nature of the droppings can potentially damage the surface of the panels over time if not cleaned properly. Regular cleaning and maintenance are necessary to ensure optimal performance and longevity of solar panels in areas where bird droppings are prevalent.
- Q:Can solar panels work at night?
- No, solar panels cannot generate electricity at night as they rely on sunlight to produce power.
- Q:I live in Sacramento, CA, and I need some solar panels for a project fo school. They don't have to be very big......just something that I can use as an example.Thanks!
- I did the same thing recently, if you'd really like some free ones then you need to look for those little solar powered lamps that people put in their yards, theyre about 0 inches tall and people sometimes line the paths through their yard with them. Maybe you can find a neighbor who doesn't want theirs anymore, or you could check local dumps for them. They each have a solar panel in the top, and they can be linked together to make more power. Alternatively, you can look on OKorder for a pack of broken solar cells, which still work fine but don't put out quite as much power as they did when they were new. However, they are very cheap. Hope this helps.
