- Q: I have a 500 watt inverter and battery but need solar panels to run my need. I want to have enough juice to run a computer and monitor and sometimes a 5w amp. I am not sure how much power is needed to run the computer (standard desktop with 5flat screen with an additional surround sound system) though on the side of the computer it says 5 amp but I know I used to run it and monitor and surround sound with a heating blanket on the same circuit which was rated at 20 amps. My question is that I would like to go and buy some panels (cheaply as I'm unemployed) from somewhere like Harbor Freight that would meet the need of the converter to supply enough amperage. So what size panel(s) or panels would I need to run this setup? If I am correct I think 500 watts is equal to 5 amps. Would this even work? Could I run a partial system where I could run some of the stuff to take a load off? I need to lower my electric bill somehow. Thanks!
- Solar okorder in their survival discussion in the archive, this exact project was discussed at length.
- Q: Given that I am going to purchase a solar panel to charge my cell phones and other gadgets, I would like to know what the ammount of power produced by a 6 Watt solar panel is under regular circumstances. (IE partial sun, full sun, cloudy)
- That site tells you somewhat about the cost of solar panels and their MAXIMUM output. Now some who have these panels claim output, in daily terms, 8 times as great as maximum output, which says they are counting on 8 hours of effective sunlight. In California Desert that is sound. You will discover that Ontario Power grid is planning for 3 hours to 4 hours of maximum output . Based on that 3 to 4 hours of maximum output, it would take close to 20 years to recover your cost at the price Ontario pays for solar power. The deal locks you in so that you can not get more money as electricity prices go up, and do not lose if electricity prices go down over that 20 years.
- Q: I live in Sacramento, CA, and I need some solar panels for a project fo school. They don't have to be very big......just something that I can use as an example.Thanks!
- If they're just to be used as an example, go around your neighborhood, and find a yard with solar yard lights. Then ask the owner whether you might borrow one or two. If they say no, move on and find another house. I'm pretty sure someone will say yes, after you explain what it's for. They will trust you, because you could have just stolen the lights, but instead asked. Option B is to have your parents take you to Fry's Electronics, and purchase a solar item, like a motion detector light, or even a standalone solar panel. As long as you don't mess up the box, you should be able to return it later for credit. But that's borderline dishonest, because you never intended to keep the merchandise.
- Q: Pretty much, can solar panel's support the entire houses electrical needs generally, because I know sometimes the owner's can sell unused electricity back, any ideas or any ideas on how much the average home uses in kWh
- why okorder and we will tell you and everyone else what they would need.we will tell you to the dollar what it takes to accomplish your desire.thanks tommy
- Q: Which kit did you use?How easy was it to build? How much did it cost to build the panels?How many kw or watts does it produce?Any other info on the kit or panels you built would be helpful.Thanks!
- I am starting to think about solar panels as an option for my home. I have d fef one some research on panels, to be honest its all very confusing. There are many.???Read more...
- Q: i need technical and non technical details to generate MW power by solar panels
- First off, you should consider cost per kilowatt-hour (kWh) since kWh is energy whereas MW is power, and kWh is a common unit of energy used by power utilities. But first you would need to design the power capacity required, which as you state, is assumed to be MW. Average system costs = $95 per square foot Average solar panel output = 0.6 watts per square foot Average solar energy system costs = $8.95 per watt Form this information, the capital cost of installing MW = $8.95 /W * 0^6 W/MW = $9 million. The lifetime of a typical solar power system is probably about 20 years. Assuming a true MW peak output of the solar panel it would be anticipated that a daily average energy production would be peak output over about 3 hours per day, or 3 MWh of energy per day. Total production over a 20 year system life would be 3 MWh * 365 days/yr * 20 yr = 22 x 0^3 MWh So in terms of costs of capitalization of the system, the cost of Energy (/kWh) = $8.95 million / 22 x 0^3 MWh = $0.40 / kWh (approximately) This cost does not include maintenance, however, given the simplicity of these systems; other than periodic equipment replacement, which is covered by specifying a 20 year complete system replacement; other maintenance cost should be relatively low. The required surface area of solar panel = 0^6 W / 0.6 W/ft^2 = 94,340 ft^2 or a little over 2 acres of panel surface area. To be able to properly access and maintain the solar array, the minimum area required would likely be 5 to 0 acres.
- Q: want to run 400 watt heater 8 hrs a day how many solar panels do i need and batteries
- You could do that, but it would be an expensive way to go. If what you really want is heat, consider heating water directly with conventional solar water heaters, and storing it in a large, insulated tank. You can then circulate the water through a conventional radiator at night.
- Q: but is that per day, per hour or minute?How much watts does the average AC unit use?How much does an energy efficient lightbulb use?All in all let's hypothetically say we no longer use the electric company for our energy source, How many of these panels do you estimate it would take to supply our small home?
- To calculate an estimate of your power usage, follow the first link below. Although you can have whatever sized system you want (at a cost) those on solar power generally keep their power usage down by cooking on gas, not using an electric kettle, using low energy light bulbs. Powering AC would up your power requirements considerably. We run a medium sized house on 860 watts of panels in southern Spain (plenty of sunshine). That includes the washing machine, pool, and running two laptops and wireless network all day,and a ceiling fan on summer nights. Hower we cook on gas, would not consider AC, and the fridge runs on gas (though if the fridge had to be replaced I would buy electric and add an extra pv panel). For an overview of the equipment required and what it does, check the second link below.
- Q: how many solar panels in a grid tied system would it take to take see a difference in your power bill?
- Typical solar panels used on household systems generate between 00 and 50 watts each. You might get the equivalent of five hours of sunshine per day on the average. 500 to 750 watt hours per day would be the average output. Where I live that would save only about six to nine cents per day. Learn more about photovoltaic solar systems by searching for solar panels on the Internet, and in the green search box above on this page.
- Q: Its cloudy out and i have a solar panel that has 3, .5 volt cells But how do i charge it without sun any other ways?
- Just to clarify the terminology here, solar panels can be used to charge batteries. The solar panel produces electricity from the sun but you do not charge the solar panel. So I'm assuming you have 3 .5 volt rechargeable batteries connected to a solar panel in some kind of integrated unit. The batteries are probably wired in series giving you a 4.5 volt output from the unit which you can use for powering LED's, portable radio etc. The solar panel may have about 2 solar cells wired in series, each producing up to 0.5V in good sunlight, but the amount of current they produce depends on their physical size, the sun's intensity, the load being supplied, and the type of solar cells. If it has the cheaper amorphous silicon solar cells, they will actually produce some useful output on cloudy days and charge your batteries slowly. However if they are more expensive crystalline cells they will only work with good sunlight, but then they will work very well and charge your batteries relatively quickly.. If your batteries are not charging enough on a cloudy day you could connect a mains-powered 4.5V charger to the output terminals of your unit. However you may need technical expertise to make this work because of the possible presence of internal blocking diodes. You also need to ensure the mains charger has appropriate power ratings and the connection to your unit is made safely, + to + and - to - . I hope this helps.
