Solar panel working process

In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.

- 0~+3% power tolerance.
- classification for all the panels in order to improve the integral performance of system and solar panel life span.
- TUV、UL、MCS、CE、ROHS、Golden Sun certified
- Underwriting of 25years output power warranty by The People's Insurance Company of China.

Q:Reflectors or mirrors around the solar panels.......?
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:Everything about Solar Panels?!?
The okorder.com to find the info there.
Q:Why should I use a Charge Controller for my Battery and Solar Panel based on these provided details?
Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.
Q:Why don't scientists use the design of a tree for solar panels?
solar panels do not use generators, but i like your idea, very creative.though i don't see the practicality of this being used commercially, i think it would make a great solar promotional piece though! off-subject, it is time we stop looking at the upfront costs of things and start looking at what the long term costs are. most green-technology, although expensive at first, end up saving tons of resources and actually increase profits of businesses! studies show that people who work in a green building tend to be happier which benefits health, more excited to go to work due to the business's environmental ethics, are more productive because of natural lighting, and are more efficient because more work is getting done. green buildings can actually boost the efficiency of a business! thus saving tons of money and reducing tons of waste. Doesn't this just make sense to you?
Q:i am asking about the solar panels?
First of all, make sure that you are taking readings in the dark (with the solar panel indoors and covered). 0.433 is a reasonable forward voltage for a Schottky diode. Ideally, it diode should read open one way (possibly OL for your meter), and 0.4 the other way. If it's reading OL both ways, the diode is bad. You can either unsolder it or cut it out and verify that it is bad.
Q:Why aren't electronics made with solar panels?
Yes your right, solar panels (photovoltics) could be used to make electricity for small electronics. Right now solar cells are on many calculators, and even flashlight. But the problem is the lenght of time the cells take to charge the device, verses the power demand. I don;t think the size of the panels, and the amount of time needed to charge the device are practical. One think I have been thinking is that every one should have a photovoltaic panel to charge a battery. Then, use the battery to charge cell phones, MP3 palyers. The panel and the battery could be about the 8 x inches, and could sit in window, or on a dash board to get charged, then used in doors over night to charge devices.
Q:Do they make solar panels like this?
Solar panels only put out electricity when they are in the sunlight. If you need electricity after peak solar hours, you will need a battery storage system or a connection to the grid. You can run a DC device directly off of solar panels if the device uses the same voltage and amperage that the panel puts out. Your 600W lights use a ballast that takes AC current and will not work with the typical panel. Also, a 600W light will take at least 3 high output/high efficiency panels to run, and you will need more than that if you want to store energy in batteries. You are talking at least 60 sq. ft. of solar on your roof. Aside from the power you need, you are also asking for an AC current, while most solar panels put out a DC current. This is what inverters are for. There are some newer panels that output AC, but you are still talking about a lot of PV to power your needs.
Q:What do you know about solar panels?
Solar power is produced by collecting sunlight and converting it into electricity. This is done by using solar panels, which are large flat panels made up of many individual solar cells. Using solar panels is a great way to generate clean and renewable electricity to power equipment or even the average home
Q:Help with solar panels?
Unless you're very rich, you won't be able to afford solar panels that can meet the average demand of a home. In the US, the average demand for a home is 920 kwh per month, which amounts to 3,833 Watt panels if you assume 8 hours of usable sunshine and don't take into account your location. At current installation rates that's easily a $9,65 project. If you assume a 25 year useful life, it amounts to a return of 3.3% per annum at 0 cents a kwh not counting the costs of repair, insurance, the inverter, any fees to the utility for net metering if any etc. You would be better off putting $9,65 into a mutual fund until better technology or government incentives came along, in some areas, the government subsidies can make it worth your while. Also, keep in mind that in many areas, the net metering arrangements only deducts the power you've generated from your bill so you would want to size the array to meet your base usage in order to get the most from your investments. So meeting your actual needs would result in a loss on the return as there will be months where your usage is less than your average. In theory, if you put $7,208.69 into a mutual fund expected to return 4.4% per annum then you could withdraw enough to pay each month's power bill for 25 years at $0.0 a kwh and therefore be self sufficient through financial means. You would get more mileage focusing on heating and hot water as heating and hot water is 75% of a home's energy use and can be addressed with lower cost technologies like passive solar and solar thermal panels. You have to put it into perspective, it's an investment and you want a return that's competitive with your investment opportunities.
Q:Increase Solar Panel Efficiency?
If you have a way to keep silicon panels cool, that really helps. On a hot summer day, our array was down 20% in production. I sprayed a hose to wash the panels, and for a few minutes, the power spiked to 20% ABOVE normal. The usual thing to do is mount the panels exposed to the wind if you can, or at least 8 off the roof otherwise. A few lucky souls with access to free stream water on their property have been known to use water cooling under their panels.
