Q:Solar Panels, kw per hour or day ?
That means if you stick a watt meter on the output when there is maximum design sunlight on it you will get kw. If you shine the maximum design sunlight on it for hour then you get kw hour of power. In one day you get 24kw hours assuming you can get 24 hours of maximum design sunlight. Your home electric bill is typically in kw hours. At the macro level power is traded at megawatt hours.
Q:What Are Solar Panels Made Of?
Silicon. They have to compete with computer chip makers for the same supply of silicon. As solar panels are becoming more common, the price of computer chips is going up.
Q:what do we mean by efficiency of a solar panel?
Photo-voltaic solar cells use the visible light range (photons) for the conversion of sun's rays to electrical energy. The potential of solar radiation is ,353 Watts per square meter, but that is mostly a measure of heat, or infrared radiation. The visible light is actually a small portion of the spectrum. You have struck on a problem associated with photo-voltaic cells. Infrared radiation acts to heat up p-v cells (heat stress), causing them to be much less efficient. It would be interesting to see a hybrid p-v panel that is cooled with fluid or air running through it. This would increase efficiency of the p-v process while providing a heating source. This in turn could be used directly for heating or for production of electricity through a generator system.
Q:Questions about solar panels?
There are several web sites you can search for and they will provide the answer on how big of a PV Solar Array you would need for your house. Several things need to be known, such as square footage of the home, how well the home is insulated, etc. The panels come in all sizes and wattage's depending upon application, so yes they should all fit on the roof. If you have a small roof get PV panels with higher wattage's. Yes, they will work in the northern latitudes but not as efficiently as near the equator. You might need more PV panels to make up the loss in power from the sun hitting at a lower angle. Generally, all you will need to do is periodically clean the glass covering of the PV Panels to get maximum sun light on the PV cells. In my region, near the 45 th parallel, a 600 square foot home with six inch insulated walls and R40 attic insulation can purchase a PV panel system for around $40,000. That includes the equipment to tie it into the power grid and the meter to measure how much you supply the grid during the day and how much you draw from the grid at night when the sun isn't shining. There are tax credits for retrofitting an existing home, but mostly it is new homes being built that are having the PV panel systems installed so the cost is added to the mortgage and the return on the investment is paid off over the life of the System (about 5 to 20 yrs.)
Q:A couple questions about home made solar panels?
there are plenty of free sites that tell you how to install your own solar panels. Just google diy solar panels. as to how many panels you need, it depends on what all you're trying to have them run.
Q:solar panel inverters?
Investors in this ground-breaking technology include Rockport Capital Partners, Third Point Ventures and Applied Ventures, the venture capital arm of solar equipment manufacturer Applied Materials. Enphase Energy's CEO Paul Nahi said the company raised money earlier than expected due to strong demand for its microinverters. So what are these microinverters? The Enphase Micro-inverter shifts DC to AC conversion from a large, centralized inverter to a compact unit attached directly to each solar module in the power system. Distributing the conversion process to each module makes the entire solar power system more productive, reliable, and smarter than traditional solar panel inverter systems. Usually, one single inverter is dedicated to a rooftop array of panels for a homeowner. Enphase Energy, however, have built a DC-to-AC inverter that is placed on each single panel. This makes it more reliable than a centralized inverter and more efficient, so panels can generate more electricity, Nahi said. Enphase has already started shipping its microinverters and has tied up deals with several panel distributors and installers. The future of inverters? Enphase Energy has been able to improve the DC-to-AC conversion efficiency to around 95%. Because of this, Nahi predicted more companies will turn to decentralized inverters. There's been very little question on the benefits of microinverters, but people didn't think it was possible to get the efficiency levels required, he said. Now it seems that they have.

Q:Solar panels and supplementing your AC power source.?

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:Solar panels for a small gym outside my house?
Yes you can.. Use it to charge a 2 volt battery then use the battery power to run a 2 volt halogen bulb. Would be much better to power some LED's with the battery -- just as much light but will last longer.
Q:I have 700watts ups and 2V,65amp battary..i want to add solar panel to just only charge my 2v,65amp batt.?
What you are stating is that the battery you have will operate the UPS for about 2 hours before it is drained past the point of no return (technically 2.82 hours, but that would be a dead battery - most well-designed UPS systems cut off when the battery gets below about a 30% charge so that battery is not damaged. Lead-Acid batteries have about a 0%/month self-discharge rate if there is no load connected. The very best systems are as low as 3%, the worst are over 20% - and all at a 'normal' temperature. So, you will need a maintenance charger of about ten (0) watts or so - amp will be more than enough. And about any solar panel will handle that much with the proper charging connection.
