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
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.
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: I had installed over the summer a solar panel system on my house. Hers some infofor you: I live in MOThe system cost 25K (Rounded numbers)The Rebate from the utility company was about 0KThe expected tax rebate will be about 5KI have a home office from which I work and is 5% of my homes sq footage. My question is though I am getting a basic tax rebate, should I be able to claim part of this off as an expense for my home office?It seams logical since I used to deduct part of my electric bill and I there for should be able to write off part of this. I am, after all using electricity and getting a bill from the utility that is higher than it would be if I didn't have the office2. If so which amount should it be? The full 25K or something after the rebates.
- Pretty much stop existing.. Global Warming is Earth's way of pretty much saying..NEXT...We arent causing global warning its time for a change and the earth is doing it.. Mt St helens and also Mt Pinatubo put out more green house gases than anything humans did in history ..Its just a normal trend..Getting ready for the coming of another species.. just like it did with us and we survived ..that should be the question here ,how to survive the earths changes not what we can do about it. There is nothing we can do that will make a difference..Told Decaprio the same thing..
- Q: I don't have a regulator connected as they are a little expensive for a pensioner, If I join the panels into line to the battery bank from the roof should that be OK.?
- You can do this, but it isn't the best way to go. There is no problem with joining the solar panels. There are two ways to do this, in series and in parallel. A series combination will add the voltages that each panel is producing together, but not the amperages. For example, if five panels are producing 6V at 300mA each, the end result will be 30V at 300mA for a series array. A parallel combination combines the amperages of all the panels, but not the voltages. So, in our earlier example, five panels at 6V and 300mA would provide 6V and 500mA (.5A) if wired in parallel. Series-parallel combinations are also possible, giving some of the benefits of each method. This would probably better understood by doing a quick search on Google Images for series, parallel, and series-parallel. You CAN connect the solar panels directly to your battery bank with no regulator. Unfortunately, without a regulator, the connection is two-way. When the sun is out and the solar panels are producing more voltage than the batteries, the batteries will charge. However, when the panels are producing less voltage than the batteries, the batteries will instead send power into the solar panels, which will be dissipated and wasted. The panels may charge your batteries during the day, but they will discharge them at night.
- Q: how much electricity will produce in Kwh by a 000 W solar panel in a sunny tropical area per day (good sunlight at least 0 hour a day)
- The equivalent full sun hours in the tropics is around 5h a day, though the sun is around for 0 or more hours. This is to do with angles of a fixed panel. If the panel tracks the sun, it would be a bit longer, maybe 8 hours. The panel is rated for 000W in equivalent full sunlight at 25°C. As the panel temperature increases to 50 or 60°C, de-rate to 800W, and multiply that by 5h = 4kWh. This varies over the year. This is the energy the panel is capable of providing, which depends on just what it is connected to. Generally an MPPT controller (maximum power point tracking) will get the best result. If charging a battery, the energy is less, because of charging losses. This is a rubbery figure because the battery may not be a simple charge/discharge cycle, but allow about 75% of the 4kWh above. Any shading on part of the panel can reduce or stop production, or cause damage to the panel even. This is what the brown marks sometimes seen on some cells in a panel are usually caused by.
- Q: Can solar panels be used for powering a water treatment plant?
- Yes, solar panels can be used to power a water treatment plant. Solar energy can be harnessed and converted into electricity to provide a sustainable and renewable power source for operating the various equipment and processes involved in water treatment. By utilizing solar panels, water treatment plants can reduce their dependence on traditional energy sources and contribute to a more environmentally friendly and cost-effective operation.
- Q: Has anyone had roof problems caused by rooftop solar panels?
- Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.
- Q: Can solar panels be installed on a multi-story building?
- Yes, solar panels can be installed on a multi-story building.
- Q: What makes them stop working after a while?
- You can search on solar panel failure mechanisms for scholarly works. Amorphous silicon thin-film panels go through an annealing, and power drops off after a couple years. This includes most of those flexible rubber mat type panels. That's why those are not used on serious installations. Serious panels intended for rooftop service generally come with a 25-year warranty, suggesting that the technology is more reliable than your washer, dryer, TV, computer, dishwasher, or water heater. One brand of panel had trouble about 0 years ago, but the manufacturer replaced all that were turned in, even paying shipping both ways. It was a problem with that particular model, not the technology. Our polysilicon panels have been on the roof for 3 years, now, and I've seen no sign of wear, yet, either electrically or mechanically.
- Q: Still researching for a car that fully uses solar power energy, suggestions would be nice to.

- Q: Can solar panels be installed on waste treatment plants?
- Yes, solar panels can be installed on waste treatment plants. In fact, waste treatment plants provide ample space and suitable infrastructure for the installation of solar panels. This can help offset the electricity consumption of the plant and reduce its carbon footprint, making it a sustainable and environmentally friendly option. Additionally, solar panels can contribute to cost savings by generating clean energy on-site.
- Q: Can solar panels be used in areas with high levels of air humidity or moisture?
- Yes, solar panels can be used in areas with high levels of air humidity or moisture. While excessive moisture can potentially reduce the efficiency of solar panels, modern solar panel designs are equipped to handle such conditions. They are built with protective coatings and materials that prevent moisture penetration and corrosion. Additionally, regular maintenance and cleaning can further ensure optimal performance in humid environments.
