- Q: How will i construct solar panel?
- For powering a something that works on DC, like a gate opener, Elaine is right, and in some cases only ONE bigger cell is sufficient due to battery storage; however if the appliance is 20v AC, then an inverter is needed also. MOST of Elaine's answer is good, but a few corrections are needed: Plywood - use EXTERIOR grade only, and even then it can warp; chipboard or waferboard is preferable as it does NOT warp, BUT is not available most places in 3/8, /2 nominal, (5/32) is usually the thinnest available, and it is heavier than plywood. DO NOT use particle board. Superglue - NO, it dries too fast to be useful, in most cases. Wires - For a single cell OK, but for larger panels the best wire is tabbing wire, (which is flat,) which is available from all commercial solar cell dealers. Be very careful soldering this to the cells, as unless you buy the expensive flexible cells, they are easily damaged; I suggest also getting flux pens with liquid flux. Diode - Necessary, but needs to be large enough to handle voltage and current. Usually 25v and 5-30 amps,, one per panel. Plexiglas - OK, but NOT as long lasting as glass; best glass is the special solar glass which is designed to pass almost all of the proper light frequencies, but IS expensive, and usually needs to be specially ordered since most glass stores do not stock it. Double panes work well with the outer pane glass and the inner plexiglas, (to protect the cell if glass broken,) IF where might get damage, such as 'ground' mounting. AND Frame kits are available for larger panels, but IF you make your own, a good table router is a great advantage. Inverter - IF used for 20v AC appliances you MUST have an inverter capable of handling the load, and the best ones are modified sine, or true sine, wave types, and even the best are less than 50% efficient. Note that they will last longer if NOT used at more than 2/3 capacity.
- Q: So, I've seen cheap solar panel kits for sale from Harbor Freight, and regardless of whether or not I were to buy a set from them or someone else, I was wondering what the process of implementing a small-scale solar system into your household electrical system would be.I've read articles that started out too in-depth or were speaking of systems on a much larger scale.Can it be as easy as buying the panels and inverter, and plugging it into a socket, or is there more to it?Some of the articles I was reading had mentioned having to contract with your electrical supplier, having to have an electrician tie it all in in some special/ necessary way, using a battery pack (would this be necessary for a tied-in system?), or using the system to only power single items, like a water heater, or plugging items into a connected battery-pack, all of which I'm not sure is necessary or needed for what my goals/ means are/ would be.
- Solar panel produces DC power that cannot be used directly by any electric device at house. Besides, it produces very little current unless its size is big as your roof. To convert DC power into AC power requires even more investment, like a huge storage rechargeable battery bank and very high power DC to AC converter . That is not worth to try it to supply whole house electricity with solar power . That might cost you at least U$20,000 to start with and never ended weekly maintenance. You could only try it just for fun to let it light up a few LED directly without the need to add any extra parts to it.
- Q: Do solar panels float?
- The ones in my neighborhood installed on telephone poles last year all have bird poop all over them and aren't generating any electricity. They can't even generate enough energy to pay for their construction, installation, and ultimately the work required to take them down and destroy them. Talk about a business case that has nothing but negative return on tax payer investment, all to further the lib agenda. All cost, 0 benefit. Classic lib business thought.
- Q: We have LED at the output of 40 watts and is used for 0 hours giving us 400 Watts-hr of energy consumed.Rechargable batteries needed are 2 V. 400/2 gives us 34 Ampere-hour battery needed. If we want it for 3 days, It would be 34x3=00 Ah. So the battery needed 00 AhNow how do I select the solar panel which can charge this/these batteries? What should be its rating?
- First, you need to make sure that your battery can take a regular 34Ah discharge without damage. The usual wisdom when using deep cycle lead-acid batteries is to allow for no greater than 50% discharge. This is to prevent the battery from ageing prematurely. Note that automotive batteries are not usually considered suitable for deep-cycle applications. Best allow for at least 200Ah capacity. Your solar panel capacity needs to take into account that whatever the nameplate output of the panel, that will be what it will produce under ideal conditions, actual output will always be less, often quite a bit less. You also need to allow capacity to cope with dull, overcast days when the light level is very low. You can get solar maps that will give you the sunshine hours and irradiation levels at your location. The solar panel capacity ends up being a juggling act between available funds/space and how critical it is that the light always works as desired. Let's say you had a 400W panel, which sounds quite generous. In the middle of winter, it may produce only 75W for 5 hours on a dull day, not quite enough to run the light for 0 hours. Would you expect several such days in a row? How many days could a 00Ah of battery capacity cover under these conditions?
- Q: how big of an solar panel do i need to power/charge my laptop?would one from canadian tire sell the right one?
- Yes. Basically, here's what you need (I'm keeping this general on purpose): The panels themselves -- how large an area depends on average power consumption and how much power you can get on average. That, in turn , depends on climate. You'd need more in Seattle than Tuscon, for example. I'd guess something in the neighborhod of 0 square feet. Depends also on haow many gadgets (printers, etc.) you have. You'll need a power storage system. Lithium gives you the best poser density (of off-the-shelf stuff) but an ordinary car battery works well and is reliable. And, of course, a control system to manage the power generation/storage/use so everything works together without that annoying smell that tells you you just cooked a few hundred bucks worth of equuipment! :)
- Q: Can solar panels power my entire home?
- Yes, solar panels can power your entire home. However, the feasibility of this depends on various factors such as the size of your home, the amount of sunlight available in your area, the efficiency and capacity of the solar panels, and your energy consumption patterns. It is recommended to consult with a professional to assess your specific needs and design a solar system that can meet the energy requirements of your entire home.
- Q: Here's a little idea I though might help everyone out in Iraq a little: How about if the US mass produces solar panels that are small enough to carry (maybe one foot by three feet) that have a regular power outlet on them to the Iraqis? We could send convoys to the people waiting in line to buy gas and give each person one free solar panel. Why?. A lot of people are buying gas to run generators for air conditioning, not to fuel vehicles. 2. It would help reduce the gas lines if people only needed gas for cars instead of their generators too.3. It would help reduce the fighting over the power grid if people didn't need the grid for their own electrical power.My theory is, once every family in Iraq has enough of these panels that they don't even care about the power grid (during the daytime anyway) it would be much easier to fix the power grid. Maybe these solar panels could even connect to and add to the power grid.
- The power we get from sun's radiation is limited by the area we receive sunshine. One square meter will have kW power from sun's radiation. For current technology, the conversion efficiency is about 8%. So one foot by three foot of solar panel only produce 80Watt. This will not be enough for your application.
- Q: Can solar panels be installed on a commercial building?
- Yes, solar panels can be installed on a commercial building. In fact, many businesses and organizations are increasingly adopting solar energy to reduce their carbon footprint and save on energy costs. Installing solar panels on commercial buildings can help generate clean, renewable energy and contribute to a more sustainable future.
- Q: I'm very interested in how solar panels work. I understand the bigger picture of how it can be used for solar heating or as a generator, but I'm lost at the smaller details. Things like: - Could my computer work on solar? It has a 900 watt power supply (this is excluding monitor/speakers) - if a panel is for example, a 60 watt panel, does this mean it will pump 60 watts a second into a battery? - Does solar heating make the water electrified?

- Q: How much roof space is needed for solar panels?
- The amount of roof space needed for solar panels varies depending on several factors such as the size and type of panels, the energy requirements of the property, and the efficiency of the panels. However, as a general rule of thumb, a typical 1 kW solar panel system requires around 100 square feet of roof space.
