Q:Whats the annual energy output of the average solar panel.?
The energy output is highly dependent on the location. For a specific area, you can look up the equivalent peak sun hours per day here: rredc.nrel.gov/solar/old_data/nsr... Let's say that it says the peak sun is 5 hours / day in your location. Then a typical 200-watt panel would have 5 x 200 = 000 wH = .0 kWh per day, or 365 kWh annually. The tables above already take into account average cloudy days, and seasons. A typical size installation would have perhaps 6 of these panels, but it could be less, or much more.
Q:energy and solar panels?
It depends on the size of the solar panels and the intensity of the solar-light. So, there's difference in every place. It's impossible to answer unless there's detail of panel size, panel quantities, average rainfall, average solar days, etc.
Q:Solar panels IRS refunds?
Not a good answer: CNBC had a news bit, that it can take 0 to 20 years for you to break even in energy costs after installing solar panels. Please don't buy them just for the tax deduction. See if you can google a calculator for this - do research. I have a brother in law that buys anything under the sun just because he gets a tax deduction. I'm sure you're not like that though. Run the numbers of what you will save vs the 2K you will spend You may never break even
Q:How can I make a sun tracker for a solar panel?
tbls0 has a good idea for the tracker, but let's take this one step farther. A clock motor large enough to move a solar panel, unless it is a very small one is going to be large, and expensive. Use the timer motor, as suggested, but attach a slotted disk to it, with a light source on one side, and a detector on the other side. As each slot comes up and allows light to pass through, this creates a one shot pulse which is used to cause a stepper motor to move position to keep the panel aimed at the sun. At the end of the panel travel for the end of the day, a switch could be set to close, bypassing the step control to put the motor into full constant speed reverse, this causing the panel to swing back to the morning position. The whole affair gets it's start up call by means of a light detector, similar to those used to turn lights off at sun up. The control would, of course be set to turn the system on to track the sun during the day. While some digital control is going to be needed, the system would not need a computer to run it.
Q:Increasing Solar Panel Efficiency?
I am a senior in highschool and one of my classmates is basically a genius by all means that I can tell. He has already been accepted yo UNC Chapel Hill. His admissions statement was on exactly this subject. I proof read it for him. Anyways the basic problem with solar energy is that we can only harness about 20- 35 pecent of the energy and even less of that is converted into energy that can acutally be used. His argument is that if somehow we could harness chloraphyll which is the chemical which plants use to harness the suns energy and incorporate it somehow into our solar panels. We could harness up to 95% of the suns energy!!! Id deffinately look into this.
Q:Question about home solar panel systems?
The $25,520 price amounts to about $8.5 a watt which is high, I would've expected between $2.50 to $5 a watt and those are dated prices so it sound like the vendor is raking the price up. You didn't mention how many months your $75 financing is for but keep in mind that at 3 kw for 8 hours a day for 30 days at 2 cents per kwh, you would generate $86.40 so you will be paying about twice as much for your solar power as you would had you bought the power from the grid. Mind you, for people on a fixed income, there is the security that the cost will not rise ( if properly insured ) so there could be an advantage to paying a premium for your power if you're on a fixed income. I'd say it's a rip off but I also believe solar has a ways to go even with subsidies before it's an economic choice and that's usually not a popular stance with the green washed crowds.
Q:Solar panel question..?
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:What are solar panels? what do they do?
Solar panel is an alternative source of energy. Solar panels are like plants, they take energy from sunlight. Only in solar panels, electricity is produced instead of oxygen. This electricity is used to power homes just like cable electricity.
Q:solar panel model HELP!!!!!!!?
There are different types of solar panels. Photovoltaic for electricity, and thermal for heating water, and passive for heating air. So it would help if you would say what type you are going to build. Theere are a lot of videos on you tube on how to make solar panels. use the link below.
Q:Best and Affordable Solar panel for home?
Solar power systems are expensive and it takes time to recover the initial investment. The cheap solar panels that you are talking must be solar heat collectors which are most common in Asia. They are the most efficient type of solar power systems for the climate in South East Asia. They are mainly used to heat water. If you are looking for this, it will cost you about 25000-30000 for a 50-200 liter capacity. If you are looking for a solar power system only, then you can expect it to cost about 50000-60000 Rs approximately for 00 Watt/hr system. With this you can run most of the appliances and lights, fans etc. and your electricity bill will only be a fraction of what it is now. Hope this helps.
