- 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: we are planing to move out of the grid. we need to operate constantly 2 laptops online - does any one can tell us how much solar panels we shall need to make sure of that?
- A laptop is about 70 to 00 W, and you have two. You also may need to power a router, and modem. So, about 50W to 250W contineous should cover it. To save power when not in use, you can let the display go blank. This will reduce your solar pannel, and battery size, and cost. You will need batteries, and blocking rectifier to store the energy for use at night, and a 300W to 400W inverter. Checkout the link below for purchasing solar equipment. You can only hope to get about 8 to 9 hours of full output from your solar pannels, and 80% efficiency. The laptops will be on and using about 200W for the 8 hours during the charging period. So your pannels, need to produce that plus 2 times more than this amount, so you can charge the batteries for the evening, at the same time. So for 24 hour operation, you will need 200W x8hrs for the laptops, plus (6 hours*70W)/8=340W avg. Total of ~540W for 8 hours. Assuming you use power saving modes when not in use, you can probably get away with 3x60W -- 520W to 600W pannel. ( Thuja is right, a few cloudy days may knock you offline) Batteries. A common low cost ( $40) automotive battery can hold about 40 Amp/hours at 2V. Under load, you may get 35 Amp hours at 0V, which is about 350Watts for one hour. You need about 80W avg for 6 hours, or ~ 2900Watt Hours. Which means you would need 9 automotive batteries. Deep storage batteries cost more, but are more durable. 6*00W pannels, $460*6 ~ $2800 Inverter $70 Batteries $400 Battery cables, rectifier, lugs, connectors $50 There are probably some other hidden costs. I was rooting for you, but it appears to be pricey. Another thing you can do, is to use the new energy efficient RF florescent bulbs for lighting. The color and brightness are excellent, and a 60W bulb only uses about 3W, and they last a lot longer as well.
- Q: I have 2 solar panels one is 5 watts 2 volts .2 amps or -The other is 50 watts 2 volts 2.6 amps or-Can I ...and what is the best way to hook them togeather to increase my amps being put back to my battery ?? I would be hooking them up to a 7 amp 00 watt charge controllerThe panels are rated 2 volt but the specs say they will produce more whennot connected to charge controllerPlease advise and should I even bother with the smaller panel ?
- You should probably ask this in the electronics section.
- Q: How much candle lights is required to operate a 205 watt solar panel?
- That's hard to tell. A solar panel produces somewhere between 7 and 0W per square foot under sunlight exposure. You should calculate the light intensity of sunlight, and then calculate the light intensity of a candle (You'll have to look that up in some physics book or the internet) and then just multiply the number of candles until you match the intensity of sunlight. Realistically, you would need so many candles that you wouldn't be able to fit them in front of the solar panels, assuming you don't end up with a huge fireball.
- Q: What is the warranty on solar panels?
- The warranty on solar panels typically varies between 10 to 25 years, depending on the manufacturer.
- Q: About how much would it cost to purchase and install solar panels for the average American house so that the house can be off the power grid and use the same amount of electricity as it normally does?
- And even though the better technology is out there, it is not in mass production. Perhaps one day it will be, but it is not there presently Silicon wafer based solar cells Despite the numerous attempts at making better solar cells by using new and exotic materials, the reality is that the photovoltaics market is still dominated by silicon wafer-based solar cells (first-generation solar cells). This means that most solar cell manufacturers are equipped to produce these type of solar cells. Therefore, a large body of research is currently being done all over the world to create silicon wafer-based solar cells that can achieve higher conversion efficiency without an exorbitant increase in production cost. The aim of the research is to achieve the lowest $/watt solar cell design that is suitable for commercial production.
- Q: I need to prepare solar panels for using in home needs electricity purpose. Can anyone could help me to know much more about it.

- Q: Can solar panels be installed on a pergola or awning?
- Yes, solar panels can be installed on a pergola or awning. In fact, these structures can provide an ideal platform for solar panel installation, as they offer ample sunlight exposure and an elevated position that maximizes energy production. Installing solar panels on a pergola or awning can not only generate clean and renewable energy but also provide shade and protection from the elements.
- Q: Does anyone know the earnings potential for the actual fitter of pv solar panels,and the electricians earnings.ty.
- it depends on your solar panel, but you can sure supply most if all of your electronics and electric stuff in your house on a sunny day. If you want to know exactly how much power it supplies and how much $$ you can save you simply have to calculate how much power your home consumes per day/month. I know of people totally reliable on solar power for their home and I too will put solar panels on my home one day.
- Q: Can solar panels be used for powering a hospital or healthcare facility?
- Yes, solar panels can be used to power a hospital or healthcare facility. Solar energy can be harnessed and converted into electricity to meet the energy needs of these facilities. By installing solar panels, hospitals can reduce their reliance on traditional grid electricity, lower energy costs, and contribute to a more sustainable and environmentally friendly healthcare system. Additionally, solar panels can provide a reliable source of power, especially in areas with inconsistent or unreliable electricity supply.
