- Q:What size and watt solar panel?
- I think that typical solar panels are 2'x4' and produce something like 800-000 wh per day. (That's 0.8 - kwh per day.) More in the summer, less in the winter, if they're aimed sort of at the sun. There are newer, more expensive panels that produce more. There are also thin film panels that are less expensive, and probably more sturdy. You then have a couple choices. In a house, you'd have an expensive inverter to connect to the utility power, so you can have power at night when your panels aren't generating anything. In a trailer, you want 2-4-6 deep cycle car batteries to store the power. Then you could have an inverter to convert that power to 20v AC, so you could use normal appliances. Or, you could buy appliances that run on 2 volts DC. Maybe a combination of both. You'll need to figure out how much power you're going to use, so you know how many panels and batteries you're going to need. The calculation is easy. Figuring out how much power you need is hard. You need deep cycle batteries because you can repeatedly charge them way up and run them way down. Ordinary batteries die fairly quickly when you do that.
- Q:Do solar panels plug into an outlet?
- They are powered by the sun. You set them up out side of the house or on the roof and the sunlight shines on them through out the day. It stores the energy into light so when you turn on a light it is from the sun's energy. Plus it can save you on electric bills.
- Q:Solar Battery System?
- A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
- Q:Easy 0 points? Solar Panels and heaters?
- Well ill start with the slorar panels, they work how there are cells in the panel and when the sun shines on it and reflects off the cells and produces energy. Next the heater is just a plane heater with a object that stores up heat over time when its on and makes it hot and the room and thats amde by a tank or whatever its connected to,to transfer heat
- Q:What if anything has been done to channel light power other than solar panels?
- Crikey yes, all these terms should be googleable Solar chimney Solar cooker Passive solar Solar trough Solar water heating Double glazing I'm sure there are more, I thought clothes lines were powered by the wind?
- Q:How many Solar Panels do I need?
- Everyday I use ,280 kWh 280 kW-hour / 24 hours = 470 kW WOW, that is a very high power level, most homes use an average of .2 kW. My guess is that you mean you use 280 kW-hour in a year, which comes to an average power of .3 kW, typical. Assuming you get, worse case, 6 hours of sun per day, for the first case, 470 kW, each solar panel generates the equivalent of 250 x6/24 = 60 watts, so you would need 470k/60 = 8000 panels For the second case, .3 kw or 300 watts, divided by 60 that is about 20 panels. Depending on where you live, you could need as much as twice that number. Plus you need charge controller, lots of expensive batteries, and an inverter. The big problem is periods of no sun. If you demand continuous power, and you have a period of, say, 24 hours with no sun because of storms, etc, then the number of batteries increases to the hundreds.
- Q:where to face solar panels?
- The following links is a sun angle calculator which I find very helpful during my days of doing project about solar panel. The calculator will give you the accurate location of the sun. Solar panel work best when it is directly facing the sun. All you have to do is key in your location details and it will provide you with two most important details: azimuth angle and altitude angle. Azimuth angle is the East angle where the Sun is relative to the South while altitude angle is the tilt angle of the solar panel throughout the day. By using these two angles, you will maximize your exposure of solar panels. However, if you are experiencing rainy or cloudy days, horizontally mounted solar panels is the most efficient.
- Q:DIY solar panels for Gride tie?
- Congratulations on your solar panel. It takes a lot of work to construct one. Tying to the electric grid requires permission from your power company, and conformance to local building codes. This generally means compliance with the National Electrical Code (NEC), meaning your panels must be UL (or similar rating from another standard) listed, for fire and electrical safety reasons. Homemade panels won't qualify, unfortunately. I really would discourage you from trying to do a jungle installation without permission, as the power distribution in a house is nothing to be trifled with. That would also likely void your homeowner's insurance, and give the bank a reason to call your mortgage, if you have these.
- Q:do solar panels have to be in direct sunlight?
- As above, but also make sure the panels you use will still produce if partially shaded. Some older panels will quit producing if you so much as put your hand over a small portion of it. Newer ones don't do this but are more expensive. As you may need more panel area to produce enough energy to fill a battery (if that is how you go) make sure you have the room/roof area for additional panels.
- Q:solar panel for computer?
- Most decent laptops can use 50W of power or more....so you'd actually need a large solar panel with good sunlight. I just looked up how big a 50W solar panel is....it's about 64x64 centimeters...which is very big and expensive! So, solar power may not be the best solution to power, or charge a laptop battery. Maybe there are some solar powered chargers that charge the battery very slowly, but probably not.
