Production description
solar panels that can always be pointed at the Sun even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going.
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.
Depending on construction, photovoltaic modules can produce electricity from a range of frequencies of light, but usually cannot cover the entire solar range (specifically, ultraviolet, infrared and low or diffused light). Hence, much of the incident sunlight energy is wasted by solar modules, and they can give far higher efficiencies if illuminated with monochromatic light. Therefore, another design concept is to split the light into different wavelength ranges and direct the beams onto different cells tuned to those ranges.[citation needed] This has been projected to be capable of raising efficiency by 50%. Scientists from Spectrolab, a subsidiary of Boeing, have reported development of multijunction solar cells with an efficiency of more than 40%, a new world record for solar photovoltaic cells.
Currently the best achieved sunlight conversion rate (solar module efficiency) is around 21.5% in new commercial products[3] typically lower than the efficiencies of their cells in isolation. The most efficient mass-produced solar modules[disputed – discuss] have power density values of up to 175 W/m2(16.22 W/ft2).[4] Research by Imperial College, London has shown that the efficiency of a solar panel can be improved by studding the light-receiving semiconductor surface with aluminum nanocylinders similar to the ridges on Lego blocks. The scattered light then travels along a longer path in the semiconductor which means that more photons can be absorbed and converted into current. Although these nanocylinders have been used previously (aluminum was preceded by gold and silver), the light scattering occurred in the near infrared region and visible light was absorbed strongly. Aluminum was found to have absorbed the ultraviolet part of the spectrum, while the visible and near infrared parts of the spectrum were found to be scattered by the aluminum surface. This, the research argued, could bring down the cost significantly and improve the efficiency as aluminum is more abundant and less costly than gold and silver. The research also noted that the increase in current makes thinner film solar panels technically feasible without "compromising power conversion efficiencies, thus reducing material consumption".[5]

- Q: I am interested in installing a home solar panel system. In my city, we get a little over 5 hours of sun, and I typically use about 800-900 kwh per month.The available roof space is small- approximately 600 sqft.The online calculators provided on various sites are not uniform, thus providing inconsistent responses with the same input data.I think I need a 5kw system approximately. Can anyone verify that and provide a link for a reasonably priced system to meet my needs? Prefer grid-tied, but off-grid is acceptable as well.Thanks!
- And at what tilt? Are there trees, poles, or buildings that cast a shadow on the roof at any time? Is the space clear of vent pipes (these can be moved, but it's extra work and cost)? Probably your best move is to contact a solar installer, and get a free quote on a system. Have them quote a system that you own, not a lease. They will do an analysis of your home, which will be very valuable even if you decide not to use a professional. If there are no professional installers in your area, that's an indication that your area may not be good for solar.
- Q: Can solar panels be damaged by birds or other animals?
- Yes, solar panels can be damaged by birds or other animals. Birds may build nests or perch on the panels, causing blockage of sunlight and reducing their efficiency. Additionally, animals like squirrels or raccoons may chew on the wires or cables, leading to electrical damage. To prevent such issues, various measures like installing bird deterrents or using protective mesh can be taken.
- Q: Are solar panels durable?
- Yes, solar panels are durable. They are designed to withstand various weather conditions, including hail, snow, and strong winds. Additionally, most solar panels come with warranties that guarantee their performance for 25 to 30 years, indicating their long-lasting durability.
- Q: Are there any fire risks associated with solar panels?
- Yes, there are some fire risks associated with solar panels, although they are relatively rare. The main causes of fire incidents include faulty installation, poor maintenance, electrical malfunctions, and extreme weather conditions. However, the risk can be significantly minimized through proper installation, regular inspections, adherence to safety codes, and using high-quality components. Additionally, advancements in technology and industry regulations continue to enhance the safety of solar panel systems.
- Q: I need to reduce the average monthly home electricity bill by powering some of the household appliances using solar panels. Can I use a 250 watt solar panel to power a medium sized upright fridge?
- Solar panel alone? No. With the appropriate storage system and inverter, perhaps. You will need to do the calculation - as follows: In a solar day that averages about eight hours, you will generate about 67% of your rated output over those 8 hours. That means you will have made 340 watts. Your refrigerator will run for about four (4) hours per day on average if you are very careful about opening and closing. If you have a 400-watt (average-when-running) fridge, you will have a small cushion that will be absorbed by inverter losses, charger losses and so forth. So, with an adequate set of storage batteries, a good charger and a good inverter, you just might be able to operate that small fridge. No icemaker, no other power drains. But, two 250-watt panels would be better.
- Q: what is needed beside the panels and do you need an electrician to hook it up
- The main components for a solar electric system are the panels, racks for mounting the panels, and inverter to convert the panel's DC power to AC, which can be pumped into the grid if necessary. There would also be various electrical supplies involved - wire, conduit, possibly a switch and/or circuit breaker. On the paperwork side, there's a building permit, permission from the power company to connect, and some inspections. Although it could be done by a homeowner, it's not a trivial project, and the best way to get it set up is to contract a professional solar installer. They all give free quotes, and can explain your various options when they visit.
- Q: I found portable solar panels used for boats etc. and was wondering how I could effectly use them for my home instead. If you have used them in the past, please tell how they worked (good or bad).
- well i highly dout that solar panels ued for boats and rvs will work the same for your house, because your house requires more energy to run then a solar power can give.
- Q: I need a 2v (500-800ma) solar panel that in can fit on a 24inx4in flat surface. Where can i get one this size and with this power?
- Build okorder /
- 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?
- 2 volt and 24 volt are both common sizes. They are rated in voltage and watts. So you add the watts of the panels and buy enough to produce the amount of watts you need. For example, if you need 400 watts of power at 2 volts, you would buy four 00 watt 2 volt panels and connect them in parallel.
- Q: OK so how do these solar panels supplement the AC from the grid? Like do they invert the output of the solar panels and sync two AC sources together? If so how and with what? Or do they convert the AC from the grid to DC and then supplement and then invert it? If so how and with what? Thanks
