Product description

60 cell multi-crystalline solar module. 40mm natural anodised frame. IP65 rated Jbox, 1m solar cable and a pair of MC4 connectors.TÜV SÜD,SABS ISO 9001:2008 certified.

Several companies have begun embedding electronics into PV modules. This enables performing maximum power point tracking (MPPT) for each module individually, and the measurement of performance data for monitoring and fault detection at module level. Some of these solutions make use of power optimizers, a DC-to-DC converter technology developed to maximize the power harvest from solar photovoltaic systems. As of about 2010, such electronics can also compensate for shading effects, wherein a shadow falling across a section of a module causes the electrical output of one or more strings of cells in the module to fall to zero, but not having the output of the entire module fall to zero.

solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.

A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricityin commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q: Where can I find good instructions to build a cheap solar panel on my own?: Building solar panels is not really a do it yourself kind of job. They are made in high tech factorys with specialized equipment and experianced engineers. It would probably be cheaper and easier to just buy some panels rather than try to make your own.

Q: Are there any limitations to the lifespan of solar panels?: Yes, there are limitations to the lifespan of solar panels. Over time, solar panels experience a gradual decrease in efficiency due to factors like exposure to environmental elements, wear and tear, and potential manufacturing defects. Additionally, the materials used in solar panels may degrade over time, which can affect their performance and overall lifespan. However, with proper maintenance and regular inspections, solar panels can typically last for 25 to 30 years or even longer.

Q: I need a solar panel for my laptop as i am going camping in the desert, and i need my laptop. There are two choices of solar panels, One is 0 watts and 2 V and maximum power current 0.56 amps. The other one is 2 watts, 2 V and no mention of current. My laptop plug says input 00-240V and .5A and then output 5V-5A. Which one should i get for my laptop. If there are other choices please tell me ill look them up on OKorder.Thanks: I'm afraid neither of these panels will do much for charging or running your laptop. If the power brick is supposed to emit 5 volts at 5 amps, that's 75 watts. Neither of those panels provides enough voltage and the power output is obviously far too small. The capabilities of solar power are vastly overestimated for small panels. Sunlight is limited to about kilowatt per square meter under ideal conditions (summer time, clear blue sky, for a few hours around noon in the US southwest). But consumer panels top out at about 5% efficiency, so your limit is 50 watts per square meter - in other words you would need about half a square meter, or about six square feet, of panel to provide 75 watts. And even under ideal conditions you will only get that much for a few hours each day. Also, the panel's voltage output is not regulated, so even if you find a panel that emits 5 volts (this would actually have to be made up of groups of 30 cells in series, as they emit half a volt each at most) you can't just connect the panel output into your laptop's DC in. You'd need a regulated DC-to-DC supply, and since that is not 00% efficient it will cost a bit of the power... now you need even more panel area. All in all, not really a practical thing to carry along on a camping trip.

Q: I am working on a project and I have to build a house with solar panels. My teacher asked me how would I get solar energy if it is rainy or cloudy? I looked it up but didn't understand. Please help me!!: Build okorder /

Q: Can solar panels be installed on a pergola or gazebo structure?: Yes, solar panels can be installed on a pergola or gazebo structure. These structures provide a suitable platform for solar panel installation and can help maximize sunlight exposure for energy generation. Additionally, installing solar panels on a pergola or gazebo can serve a dual purpose by providing shade and generating clean, renewable energy.

Q: Can solar panels be used in areas with high levels of electromagnetic radiation?: Yes, solar panels can be used in areas with high levels of electromagnetic radiation. While electromagnetic radiation can potentially interfere with the functioning of electronic devices, solar panels are designed to withstand various environmental conditions. They are typically equipped with protective measures, such as grounding and shielding, to minimize the impact of electromagnetic radiation. Therefore, as long as the solar panels are installed correctly and maintained properly, they can continue to generate electricity efficiently even in areas with high levels of electromagnetic radiation.

Q: Ok so I am planning on buying a solar panel. I am doing it to possibly sell the energy that it stores. It is a 20 watt panel so I am just wondering if every week or month if I sold that energy that it stored would make me a good profit. I am not hoping for thousands of dollars a month..just like 00? The solar panel cost me $,00 so if so, how long do you think it would take to make good profit. Also, how much would I make every week or month?: I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel /solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.

Q: I'm wondering if the cost of the panels and equipment have come down enough to make them viable in areas like Seattle or Vancuver for example.: Take okorder /.. You need to keep in mind that as long as you are renting your electric from the public utility you are doing just that and renting. You can resale the solar electric system if you move or if you just want to sale it and get some of your money back if not 20 % extra. Then all the years you used the system was all free electric. So it is already viable as you put it. Anything other then buying a system would not be. Here is a thought. The housing market slumped and if you paid 50K for your home it is now only worth if you can even sale it about 00K. Not worth the money but people are still buying homes even if they are not worth what they are being sold for. And then the cars and trucks people buy will never pay for them selfs but people still buy them and spend extra the more wasteful the car is. So why does solar have to pay for it's self or prove it's self? It has many times over but because you can't drive a solar panel drunk and party out in the bars with it is is not worth the money. I guess the is just being human and a double standard. What about the big up front cost of solar? I remember a 20% up front cost when I bought my home and my car and it is the same 20% or less for a solar loan. Plus the value of solar is going up not down like with homes and a car is not worth but half what you paid for it the minute you drive it off the car lot. I can only see good from solar un like other things we buy.

Q: What sort of maintenance is required for solar panels....?: New sunlight panels are easy and shiny they usually look cool. Then they get dirty with dirt and particles caught on the wind and residues left in the back of by rain and birds. Solar panels need to be by and large cleaned and maintained to be able to hold them running effectively and maximize the quantity of sunlight they convert into electricity. Unlike home windows your sun procedure wants to have a clean and clear surface to make sure they are working at their highest efficiency. If they are not at their surest performance it approach they are not producing the amount of electrical energy that they might be. Sun panels will attract filth, dirt, soot, pollen, tree sap and salt crystals in coastal areas creating a nice layer of dust. This sediment reduces the amount of light reaching the silicon cells underneath the glass floor and reduces the panel's effectiveness. A solar panel that has on no account been cleaned would be producing almost a 3rd less power than it or else could be. Some have mentioned a ten to fifteen percentage lack of sun output as a result of dirty panels. From the ground the panels may just appear to be clean, similar to your windows. Up close nevertheless you will see the grime that has built up from the grime and pollution within the air. A extra visible deposit that can be left on panels is fowl droppings. These tend to wholly block the sunshine from areas of the photovoltaic panel and may colossal scale back its effectiveness. See much more about sun panels preservation beneath link

Q: Is this true in a dc system? What if my battery current is negative?: I am not sure about your question ? If your Q is, what is the solar panels current output, it is 8.73A regardless of the load. If the Q is, How much extra current is available in this circuit, the answer is 3.58A ( 8.73 - 4.32-.83= 3.58)
