Poly Solar Panels 250W is designed for large electrical power requirements. It is the optimal choice for both on-grid and off-grid power systems. Solar panel offers high performance of power per square foot of solar array. Poly Solar Panels 250W of Monocrystalline silicon(c-Si): often made using the Czochralski process. Single-crystal wafer cells tend to be expensive, and because they are cut from cylindrical ingots, do not completely cover a square solar cell module without a substantial waste of refined silicon.If you have interest in Poly Solar Panels 250W ,please contact us!

Q:Can solar panels be installed on public parks or gardens?
Yes, solar panels can be installed on public parks or gardens. In fact, installing solar panels in these areas can be a great way to promote renewable energy, reduce carbon emissions, and generate clean electricity to power nearby facilities or feed into the grid. Additionally, solar panels can provide shade for park-goers and enhance the overall sustainability of the space.
Q:I've been looking into solar panels. They are fairly expensive ($35k or so). My state has some rebates and grants available. Is anyone aware of any federal grants and rebates other than the federal tax credit? We are subject to AMT tax and can't take the credit. (Which is ridiculous, is the federal government committed to conservation or aren't they??????)
I run my entire home off of solar . I'm really handy when it comes to building things from junk and buy broken cells off OKorder . I glue and solder them to make 2x2 cells so my panels are 6x6 foot each normal size is allot smaller and getting plenty of power dirt cheap but the gov doesn't give me crap and i really don't give a crap because what i have into mine payed for them self in a years time of paying the power company . Now if i was to buy the system i built there's no way it would be worth the wile . The only way the government is interested is if they can tax you that's not just conservation that's everything. I do get a kick out of the rich blood sucking power company when all the lights go out in the neighborhood and there knocking on my door trying to figure out why my house is lit up like a Christmas tree
Q:Can solar panels be installed on government buildings?
Yes, solar panels can be installed on government buildings. In fact, many governments around the world are actively promoting the adoption of renewable energy sources, including solar power, in their buildings to reduce carbon emissions and promote sustainability. Installing solar panels on government buildings not only helps in reducing energy costs but also sets an example for the public and encourages wider adoption of renewable energy.
Q:If this was sold back to the grids what would be the profit i would stand to make per day on energy received in these panels? How did you come up with this answer?
I'm putting in a $00,000 solar wind project on ST Thomas, Virgin Islands so I have some experience here..... ) depends on where you are...the further north the less efficient the panels are because early morning and late afternoon sun hitting at a great angle isn't anywhere near as good as noon hitting perpendicular..........the US Department of Energy has a solar calculator showing how many hours a day over the year you get enough sunlight to actually run the panels....in the Caribbean the answer is 6 so in Wisconsin you might only get 4 really usable hours a day, Nevada 5, Seattle...forget about it..... 2) the panels I'm putting in are ( roughly) 2 x 3 feet...you would need access around all four sides of a panel...you are NOT going to crawl 35 feet across an array to fix a unit in the middle......so lets say you get 35 panels tall ( 70/2) by 2 wide (3 foot with a 3 foot access area between each row = 72/6) or 420 panels. Each puts out 75 watts at max. So you are cranking out 73,500 watt hours, or 73kW. If your local utility buys back ( net metering ) the juice at, say, 20 cents a kWh, you get $4.75 an hour. If you have 4 usable hours a day x 365 x $4.74 you get back something like $20,000 a year. You pay about $7.00 a watt for a panel. The 75 watt panels are, rounding up, $200. each. Times the 420 panels number is $475,000 dollars. Add in about $2,000 for the inverter to change panel volts to power company volts, and maybe another $20,000 for installation you are looking at $500,000 AT LEAST to put in the system you propose. AT $20,000 a year in sales, its 20-25 years payback. Now, you can play with these numbers up and down but you still get the answer of A LOT of money to buy and build and a LONG time till payback.
Q:I been considering to get a solar panel system but I don't know if I'm going cut my electric bill every month , It's a lot of money to spend and I'm not really sure
I'm waiting for the gov't to do right thing and subsidize my purchase!
Q:I need help?!!
benefit- It makes use of the Suns organic engery to produce potential for a house/employer which saves money as against employing potential from the community materials for electricity. it will keep away from lots of money in case you reside in an area that is sunny a super style of the year. disadvantage- You extra suitable wish that is sunny for a on an identical time as to construct a inventory pile of potential. It somewhat relies upon on your desires for potential, in case you do no longer use incredibly some it and stay in a sunny section a super style of the year, then you incredibly could desire to have a super style of potential that only kinda sits there. yet once you reside in an area it somewhat is frequently cloudy all year around then image voltaic panels does no longer be superb for you.
Q:Can I add reflectors or mirrors around the solar panels to increase the power they generate?
In the 70's when silicon was really expensive, they played with using fresnel lenses to focus the sunlight on small solar cells but these panels had to be on heliostats and aimed directly at the Sun. These days, with nano-technology, there's a renewed interest in the concept but the fundamental weakness is that there are diminishing returns, at some point, it's just less expensive to have more solar cells.
Q:How much Electricity does a standard Solar panel producein terms of Watts and in terms of Units( i.e. electricity meter attached in our House)If I have 20 Solar panels and an inverter , how much electricity will I Be able to harness and store (state that in terms of volts)Can I run Arefridgerator, Iron, Heaters, Plasma T.V. and other high Electricity Consuming Devices.
Take a look on OKorder at some of the books on how to design solar energy systems. It is a bit more complicated than you might expect. I'm not sure what you consider to be a standard solar panel, but the 3' ones I have produce about 5 watts of power in full sunlight. Put simply, you need to convert the power from the solar cells (variable voltage) into a constant voltage usable for charging a batteries. Most of the low cost modules for this purpose can't handle more than about 00 watts. Larger systems are available that handle thousands of watts but they are quite pricey. Since you can't take out more than you put into your battery system, you can calculate about how long you can run a high-current appliance based upon its wattage rating, that of the battery system (adjusted for loss of converting to AC), and the charging system.
Q:Can solar panels be damaged by hail or other flying debris?
Yes, solar panels can be damaged by hail or other flying debris. Hailstones, especially those larger in size, can potentially crack or shatter the glass surface of solar panels, impairing their function. Similarly, flying debris during storms or extreme weather conditions can also cause physical damage to solar panels, affecting their efficiency and performance. To mitigate these risks, solar panels are designed to withstand certain levels of impact, and some manufacturers even conduct rigorous testing to ensure their durability in harsh conditions.
Q:okay so i want to know if solar panels shine. ------(MY Q'S ABOUT BLINDNESS DOESN'T MEAN PERMANENT OMG I CAN'T SEE! BLIND BUT THAT WE JUST CANquot;T SEE AT THE MOMENT BECAUSE OF THE LIGHT.)------------------------------like if/when they face the sun is there a glare to the people around?-if there is would the person have to look directly at it? -Could it reflect off of other objects and cause temporary blindness or just shine light in person's eyes?-if there were windows and mirrors near the solar panel would it affect a person's sight?-and if it did for how long would it hurt or take affect?-and is this physics? like-solar panels and how they work is that physics or some other category?
The problem with solar panels is that they often come with textured glass. This makes that the reflected light is scattered +/-0°. Therefore the 0.5° sun-disk small as it aprears in the sky will be blown up 40 times to a 20° reflection disk on solar panels.
