Product description
A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.[2] It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.
Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.
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: I know that there is a life expectancy for solar panels, and I suppose, the technology involved. Any information?
- Who okorder /... That suggests that the power the panel output will degrade a little less than % per year. We've had ours up for 5 years now, and I haven't noticed a steady degradation pattern. But the yearly weather is so variable, it's hard to see a pattern. The 2nd year's production was actually higher than the first. It could just be clearer skies or colder temperatures, who knows.
- Q: I have a rental property and use a 230-Volt 6-Amp Pool Pump.I would like to use a solar panel to run it when the house is empty, using mains power when guests are here.The building is in the Caribbean so plenty of sun!!I wanted to run it quot;directand not use batteries. Is this possible??What size panel would I need? A DC invertor too??Thanks!!
- Why don't you use the mains as the battery with net metering. That way you don't have to have two pumps, a DC pump for the solar and an AC pump for the mains. A 230 V, 6 A pump draws 3.68 kw. A typical solar panel produces about 400 watts so you would need about 0 solar panels which should run you about $20,000 US. Of course, you may not need to run the pump continuously but in order to use fewer solar panels for sporadic use, you would need the batteries or the net metering. Keep in mind that with the costs of the panels, you will be paying about 38 cents a kwh. Grid power usually costs around 5 cents a kwh.
- Q: Polycrystalline solar panels are good or single crystal solar energy is good
- Pre-monocrystalline silicon solar cell photoelectric conversion efficiency of about 15%, the highest reached 24%, which is all types of solar cells in the photoelectric conversion efficiency of the highest, but the production cost is so large that it can not be a large number of extensive And commonly used.
- Q: Aren't batteries bad for the environment?Toxic?Expensive? With small solar panels phones, iPod's, laptops other small electronics could be smaller, slimmer, more efficient cost people less to charge every day. Maybe a small battery inside as a backup and to store the Solar energy for night time. But overall, batteries should be optional. So big question:Why aren't electronics being produced with solar panels?
- Yes your right, solar panels (photovoltics) could be used to make electricity for small electronics. Right now solar cells are on many calculators, and even flashlight. But the problem is the lenght of time the cells take to charge the device, verses the power demand. I don;t think the size of the panels, and the amount of time needed to charge the device are practical. One think I have been thinking is that every one should have a photovoltaic panel to charge a battery. Then, use the battery to charge cell phones, MP3 palyers. The panel and the battery could be about the 8 x inches, and could sit in window, or on a dash board to get charged, then used in doors over night to charge devices.
- Q: OK, so if you put solar panels up on a roof, they are busy turning the sun's energy into electricity. So, does that mean the roof (and therefore the house/structure) stays cooler as well? Or does it still get hot, because . . . I dunno, maybe the panels don't convert all the energy, and the spillover still heats up the building.Any links or URLs to scientific answers would be appreciated, but I don't mind hearing from the Average Joe or (Joelle).
- I okorder
- Q: And how do you choose the best one for the best price?I saw a 400 watt monocrystalline solar panel
- The polycrystalline solar panel has a longer life-span and has a higher efficiency. What this means is that from the energy that 'hits' the solar panel, more is caught and used to convert into electrical energy. A polycrystalline solar panel will have an efficiency of about 4%. The monocrystalline solar panel has a similar efficiency but the cells are prone to sunlight, so the efficiency drops over the years.
- Q: I've heard that solar panels have back-up batteries for when it is cloudy or rainy that day.. is this true?
- 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: How do solar panels impact the environment?
- Solar panels have a positive impact on the environment as they generate clean and renewable energy without emitting harmful greenhouse gases or pollutants. By reducing the reliance on fossil fuels, solar panels help combat climate change and improve air quality. Additionally, their installation requires minimal land disturbance, and they have a long lifespan, making them a sustainable energy solution.
- Q: if you know the area of the panel can u calculate for the wattage or voltage of the panel..
- One square meter of solar panels can produce up to 50 watts of maintenance-free power for up to thirty years. The most common solar panels are for 2 V applications. For sq meter: I = P/V = 50/2 = 2.5 A A single solar cell always produces a voltage of approximately 0.5 volts, regardless of its size. For higher voltages, you have to connect individual cells in series to add their voltages. The larger the solar cell, the greater the current will be. You can also connect cells in parallel to increase current. Hope this helps!
- Q: How do solar panels affect the property's corporate social responsibility?
- Solar panels can positively impact a property's corporate social responsibility by reducing its carbon footprint and dependence on fossil fuels, thereby contributing to environmental sustainability. By generating clean and renewable energy, solar panels help to mitigate climate change and promote the use of clean energy sources. This demonstrates a commitment to environmental stewardship and can enhance the property's reputation as an environmentally responsible organization. Additionally, the installation of solar panels can inspire and encourage others to adopt renewable energy solutions, further promoting sustainable practices within the community.
