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:Numbers behind Solar Panels?
For comparison, 36 of these make a normal 2V x 50W panel. Note they are not tabbed. This means you have to find a way to connect them yourself. The tabs are probably spot welded on by the suppliers. A supplier below has kits of these with tabs, as needed to connect them together. These are not suitable for grid connect, because the higher voltage needed makes do it yourself panels a dangerous and litigious thing to have on your roof. Maybe you could buy a smaller pack from the link below to compare tabbed and untabbed and work out what to do. Your power calculation is a bit incorrect because the sun is only present some of the time. The 36 cell module would produce 50W when square on to the full sun. The sun may be out for around 2h a day in some places and times of the year. However it is the equivalent of 5h full sun, because of the changing angle throughout the day. Look this up on the internet for your region. Temperate zones may be a lot less. One pack in your link is 36x3 = 08 cells. Thus 50W per pack x 5h a day gives 750Wh per day and 274KWh/y. In reality it will always be less because of regions, weather, clouds, dust, inefficiencies, aging of cells.
Q:Is there a free solar panel program for veterans?
yes. there is a free solar panel program for veterans.
Q:Do I need to run a ground form my solar panel?
Did you ever evaluate possessing the equipment your self? Why not take all of the tax incentives your self? Why pay an identical fee in 7 years from now? that may not a honest deal. Did you ever verify with them what might ensue once you want to sell your place before the tip of the lease? Our enterprise has put in photograph voltaic panel structures in 8 states in the Northeast and we adore to work out the tip consumer identifying to purchase the photograph voltaic array. we glance on the lease ideas as a final motel if there's a financing situation. the guy who owns it makes the money, short and easy. concerning utilising it whilst the capacity is going down, the inverters can not function whilst there is not any grid capacity. you may proceed to function utilising a battery equipment and yet another inverter, yet that will advance your fee extremely plenty as properly. you should use yet another generator as properly, which may be a less costly fee selection. you want somebody who's staring at on your appropriate interest, and not their very own investor. you've got your equipment value paid returned in basically some years!
Q:Adding Solar Panels to my home in Portland, Oregon?
I wish it was that easy! Maybe it will be soon. But at this time, no, there isn't. And if you have a solar collection system, you have to have a way to store the energy when you're producing more than what you are currently using. That usually involves an expensive battery array. But it's necessary. The power coming directly from the solar panels will be erratic and sending it to the battery array for storage and then use allows for the home to draw a consistent level of power. And this battery system also allows for storage of electricity for use when the sun isn't shining like at night. The system should be set up to use your power first, then go to the grid. It should also allow for distribution to the grid when your system has stored all the power it can and that's when your meter will run backwards and the power company will be paying you! There are a lot of federal and state income tax rebates for alternative energy installation costs. Check out what Oregon might toss into the package along with the Feds and see where you might come out.
Q:Information Regarding Solar Panels?

Q:What is a solar panel?
Solar panels are used to gather solar energy from the sun. Solar panels help maintain a clean and sustainable environment; using solar panels to gather the sunlight is a type of renewable energy. After collecting sunlight, the panels convert the energy into electricity
Q:Solar panels on the roof?
Lots of folks are installing them in my neighborhood in the Mid-Atlantic. I'm going to hold off until I can ask my neighbors how much their electric bill has gone down, after they've had the panels for a year or so. I don't see any reason to rush into it. Also, I'm a little concerned about what happens if a leak develops in your roof during or after installation. Who pays to fix that? That, plus the west side of my house faces the street, and I don't think I want my solar panel array to be greeting guests and visitors...I'm just not that in love with the looks (although the shingle- or tile-like versions of panels that Tesla is advertising would not be bad). So the panel installers would have to be satisfied with an east-facing installation on the rear slope of my roof.

Anatomy of a Solar Cell 5. Energy Loss in a Solar Cell 6. Solar-powering a House 7. Solving Solar-power Issues 8. Solar-power Pros and Cons 9. Lots More Information 0. See all Physical Science articles You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
Q:Efficiency of solar panels?
Efficiency of photovoltaic panels usually describes the ratio between the energy of the sunlight falling onto the panels and the electric energy you get out. This number is, for commercially available panels today, usually in the range of 2...9 %. What you are asking is something else. The power from the panel depends on the light falling on it. A panel rated for kw peak will deliver that kw under a clear sky, with the sun orthogonally above the panel. For a fixed mounted panel, that is true (at most) for two days every year at noon. At any other time, the output is less. Therefore (at least for the area I live in), some people build databases (and Excel tools) in which the various variables are considered: - inclination of the panel - orientation of the panel - average sunshine duration during a year Plugging in these numbers, I get theoretically for my roof an electricity output of just over 000 kWh/year per installed kWpeak of collector power. If you set up a tracking panel (following the sun), the energy output of the panel will be higher, but so will be the cost for the mounting and the area needed to set up the system.
