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.

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.

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.

Q: if car companies install solar panels on cars, like in all the car were the sun can reach that would reduce the consumption of gas in the summer, and might save some energy for winter and if that energy is not enough they can use gas or electricity i think that would be a lot of savings, and less contamination i don't know that is my idea what do you people think?: I have a panel that might be a square foot or so plugged into my cigarette lighter. It will run the radio and help with reducing the amount of time the alternator needs to run, but won't completely run the vehicle. If I had an electric vehicle, I'd want to coat any large surfaces with them. Still wouldn't completely run the vehicle, but every bit would help.

Q: I'm building a solar panel for the first time and have the tabbed solar cells. I put together 4 strings of 9 cells. And the cells are each 0.55V, 3.6A.Because I'm going to be using the panel indoors and leaning it up against a window pane, I put them in a 24x36 inch poster-size frame. The frame has a plexiglass cover and a thick cardboard backing. My question to you is this. Will the cardboard backing up against the metal underside (positive side) of the solar cells be ok? I don't know if it may catch fire or if holes may burn through when there's full sun.My guess here is it should be ok. But maybe I'm wrong. If I am wrong, or if something should be put in between, please let me know what I should use.Thanks everyone!: Build okorder /

Q: i don't know very much about it, but can you somehow take off the little solar panels off of the outdoor light things and make it so you can hook an outlet up to it and plug in to it like a phone charger for electricity.: Little solar panels on lights are very low power. The battery in one such may be 0.5 Amp-hours and .2 V ; it may be different but it should be marked on the panel/battery/manual. An outlet in your house is designed to run on 20 V (typically in N. Am.) and they run on alternating current (AC) whereas the panel generates direct current (DC). (If you don't know the difference, do not worry to much but just understand that they are not directly compatible.) You therefore need an inverter to change DC to AC (and lose some although inverters are now very efficient). But the amount of power generated by those panels is still very small. That is why solar lights are low power (just a few watts in most cases). To make things even more irritating, phone chargers do not work off 20 V AC as you are charging the battery and need a low voltage DC -- which is what the solar panel is giving you. It is almost certain that the voltage from the panel will be less than the voltage required for the phone. The charger is mostly cable but there is a black box incorporated and it should say what the voltage and current output are (the input will be 20V). So you should be able to overcome this not by hooking up the panel to a 20V outlet and then plugging the charger in but by hooking up the panel to the phone directly if you can get enough voltage out of the solar panel (or hook up several) and if you fashion a connection device. They already make them -- solar battery chargers and I am sure you can enter that into a search engine and find loads. Typically the panel alone is much more than a solar light -- which shows the relative power requirements.

Q: (For a project)I know they are made of silicon, but I want to EVERYTHING they are made of. Ex Metal (What kind)Please tell me everything used from their production to the finished projectThank you: photograph voltaic panels take power (and in all probability some oil for the plastic) to fabricate, yet that power, and the carbon footprint, is paid for many circumstances over in widespread operation, via the electrical powered energy that the panel generates. The life of the middle photograph voltaic cells is long (there are nonetheless some panels from the 970's that are nonetheless out and dealing), and contemporary panels are oftentimes warranted for 25 years, showing that even the manufacturers have self assurance in thier lifespan. yet whilst it ultimately comes time to eliminate the panels, the aluminum physique is as particularly recycled as the different aluminum, and the tempered, low-iron glass could properly be recycled, too. The plastic substrate is unavoidably solid - it has to stand up to the solar for some years. i do no longer understand what could desire to be achieved with that. The cells themselves are a intense grade of silicon, which has fee on the scrap industry. some panels are no longer made up of silicon - yet lots of the factors could desire to be recycled in a similar fashion. i'm no longer attentive to any intense panels being dumped or discarded at present. they're worth lots, even broken, that some hobbyist or surplus place will purchase them.

Q: Can solar panels be used in areas with high levels of lightning activity?: Yes, solar panels can be used in areas with high levels of lightning activity. However, it is important to ensure that the solar panel system is properly grounded and equipped with surge protection devices to mitigate the risk of damage from lightning strikes.

Q: How about using Solar Panals to provide the electrical power to separate the H2 from the O? H2 would be fed into the engines carburator like a gas/air mixture ratio, but H2/air mixture ratio instead. How would you control the exact measurements?: H2 has more energy per weight – but requires twice the volume of fuel. It is unsafe to transport as a liquid or gas (usually in a carrier medium of some sort) Solar panels are expensive (low output per $) and expire after some use. They are dirty and energy inefficient to make too. However: hydroelectric, wind, and sea technologies may offer some improvements in costs with oil prices as high as they are.

Q: What is the maintenance cost of solar panels?: The maintenance cost of solar panels is generally low. Routine maintenance such as cleaning the panels and checking for any damage or debris is recommended, which can be done by the owner or a professional. Additionally, occasional inspections and repairs may be required, but these costs are minimal compared to the long-term benefits of using solar energy.

Q: Has anyone had any experience building their own solar panels for home use? I have seen on the news lately that people are utilizing solar panels to power their hot water heaters to save on their power bill.: Hey David, yes, we have built plenty of them. If you are into the do it yourself world, the easiest type to build is the Batch Preheater type. What you need is an old water heater, something small, like an under counter model, 0 to 30 gallons in size. It has to be one that hasn't rusted out yet and started leaking. We stopped at a local plumbing place in town, they are always throwing out units they have removed from homes because the new owner wants a larger unit, or gas versus electric, and so on. He sold us a pretty recent model for $0. Take the water heater home, and strip off the outer metal housing and all the insualtion so all you have left is the tank. Clean it up, and paint it with black paint. Now build a wood enclosure, something the size of a dog house that your tank will fit inside of. Use a glass panel for one side of the roof. What works best is an old window pane someone is throwing out that is about the right size, then build your dog house to fit it. When it's done, put some styrofoam insulation panels around the back and side walls to keep the heat in when the sun shines on it, then mount your tank inside. Put your dog house someplace in the sun, run the cold water that normally feeds into your water heater into the tank (in the cold inlet side), then run a pipe from the outlet of the tank to your regular water heater. We have one just like this installed in the northern midwest, it works great about 7 months of the year. Usually in the summer if it's about 75 degrees outside, the water comes into the house at around 00 degrees, then the regular water heater only needs to add another 25 degrees to the water to finish it off. Since the water starts out at about 56 degrees, the solar preheater ends up doing about 65% of the work. In the winter, we simply drain the tank and lines to and from it, and route the cold water directly to the regular water heater. There are some designs on line, try googling, Batch Water Preheater. Take care, Rudydoo

Q: I live in a higher LATITUDE so in the winter months, there is a limitation in the amount of sunlight available, but will this impediment restrict the ability of solar panels to function due to the lack of sunlight involved?: But int the summer months you will have longer days than someone on the equator. Depending on your local power company, you may be able to back feed into the grid and draw back out the same amount a few months later.

Q: if you know the area of the panel can u calculate for the wattage or voltage of the panel..: You need to know how many solar cells are in the panel and what is the rated current each cell will produce. This information should be listed on the panel. Each cell will produce from 0.5 to 0.55 volts DC per cell and each cell will produce a current that is dependent on the size of the cell and the type of material the cell is made from. If the cells are connected in series then the voltage of each cell will add together, that is if you have 30 cells connected in series they should generate about 5 to 6.5 volts DC. If each cell generates .2 amps, then you multiply the voltage of 5 volts DC times .2 amps DC equals 8 watts of power. The current of each cell does not add together when you connect the cells in series only the voltage of each cell. If you connect the 30 cells in parallel then the current of each cell adds together but the voltage of each cell does not. That is 0.5 Volts DC times 36 amps equals 8 watts. The power (watts) produced will be the same. See our blog on the products page to see how to connect solar cells in series and in parallel. We also have a PDF file of solar cells and their rated output current sorted by watts per area and their manufacturer.
