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.

The basic unit of a solar panel is a solar cell, which usually consists of one or two layers of silicon-based semiconductor wafers. When struck by the photons in sunlight, the solar cell generates an electrical charge due to the "photovoltaic effect" – which is a pretty good name, since it produces voltage from photons. The flow of these electrons moves in a steady electrical current from one side of the cell to the other.

Dozens of these PV cells are packaged together into solar modules, which in turn are packaged into solar panels that are mounted on a rooftop and arranged to maximize their hours of exposure to direct sunlight. Because the electricity generated by all those solar cells is direct current (DC), it is then sent to an inverter that transforms the power into the same alternating current (AC) used by the appliances in your home and the local utility electricity distribution grid. Increasingly, these inverters are getting "smart," providing data monitoring for solar installation performance and other grid integration services.

 

 

Q: can anyone help me? i was thinking of installing solar panels to cut bills but would it be a waste considering its gonna need a circulating pump running almost 24/7 (which will use electricity) and even still will only provide me with quot;warmwater? also would it be possible to install the solar panels for the sole purpose of providing sufficient power to run electric heaters instead of using gas/oil? this way allowing me to have a warm house without the expensive bills. brobably talking about running 7 heaters/electric radiators.
Are you thinking of installing electric solar panels or thermal solar panels or both? It would be better to install electric solar panels for electric heating. You can run 7 heaters as long as you do the calculations for the number of panels need for the daylight hours, and the required battery bank to supply the required power.
Q: where to find used solar panels?
IF used panels are available, they are probably worn out and NOT putting out the power they were designed for. (They DO wear out!) I do NOT know of any place they are sold.
Q: I have several 6v 4.5a sealed lead acid batteries. I would like to hook one of them up to a solar panel and have it stay charged from the solar panel all the time, but not overcharged. Is there a simple way to do this with an IC or something? I am only a beginner with circuits so I want it to be something very easy to make. Basically, I want it to stay charged all the time so it's available if I need it for a power out or something.Thanks.
Yes, you can purchase a solar photovoltaic array to keep your batteries charged. You will need a Photovoltaic Cell Panel that produces 27 + watts (6volts x 4.5 amps = 27 watts) at 6 volts of electricity, a Charge Controller that allows only 4.5 amps of power through to the battery and will reduce the amps as the battery nears full charge and shut off the Panel when the battery is fully charged, and a 6v. Battery. Figure you will need a photovoltaic panel capable of producing a minimum of 27 watts if you are going to charge a completely dead 6 v. battery in one day. (with a clear sky). The way the system works is the sunlight strikes the cells on the panel and releases the excess electrons in the cells, they travel along central wires to your battery and charge the battery. When the sun sets, the procedure is reversed and the electrons flow backwards from the battery, into the photovoltaic cells. That is where the Charge Controller is needed. It acts a one way gate and lets the electrons go into the battery, but won't let them go backwards to the Panel. Just set your panel in the sun at the optimum angle for the season and your latitude on earth, connect the charge controller and then the battery, and it will keep your battery charged. Don't waste your money on the small wattage solar photovoltaic systems that claim to keep your battery charged. They simply can't do it unless your battery is in like new condition and is fully charged when they are hooked up. If you battery is a few months old, the small wattage photovoltaic systems can't keep up with the loss of power from sulfation inside the battery.
Q: Are there any tax credits available for solar panel installation?
Yes, there are tax credits available for solar panel installation. The federal government offers a solar investment tax credit (ITC) that allows homeowners and businesses to deduct a percentage of the cost of their solar panel system from their federal taxes.
Q: Solar panel packages have different levels of power. For instance you can get a kw system but is this kw per hour or day. How does this work?
A kW is an on the spot degree of means. A kWh is a level of means produced via the years. A KW array produces an on the spot means of 000 watts. whether that could be a 2V panel which skill it produces eighty 3 amps of modern-day. In 3 hours it produces 3kWh (kilowatt hours) of electrical energy, no longer 3kW. A 3kW 2V array might produce a similar quantity of electrical energy in one hour at 079 amps.
Q: Can solar panels be used in areas with high winds?
Yes, solar panels can be used in areas with high winds. However, it is important to ensure that the solar panels are properly installed and securely mounted to withstand the high wind conditions. Reinforced mounts and sturdy frames are typically used to anchor the panels securely in place. Additionally, frequent inspections and maintenance might be required to ensure the panels remain intact and functional in such environments.
Q: i need technical and non technical details to generate MW power by solar panels
Sorry if I don't have all the specifics you asked for, but Sun Power makes the most efficient solar panels on the market, at close to 20% efficiency. They have made cells with up to 25% efficiency in the lab. That doesn't make it the cheapest but means the most watts per square foot. Thin film panels are cheaper to make but not as efficient. They are about half as efficient as conventional silicon panels. First Solar makes the cheapest per watt right now. So I guess that makes them the actuall cheapest manufacturer. They are able to make them cheap enough to beat out the conventional silicon panels on a per watt basis, despite being less efficient. A company called NanoSolar has the price down close to First Solar's price. These are manufacturers. But they do installations and build utility and commercial scale projects. NanoSolar is less far along in commercialization. They have products, but probably need to wait for the stock market to be more favorable for IPOs, so they can go public and raise the money to move up to scale. The other two are already public.
Q: I need a list of worldwide solar panel manufactures from china, US, Spain, Germany, Japan etc...Can any one direct ne to such place?I rather it will also contain comparison of parameters like efficiacy, quality etc and to be divedied by country of manufacturing.Thank you
Actually Ofir, it is much easier and less expensive than you might believe. What you need is a magazine, like, Solar Today. There is only one that I am familiar with that gets into the nuts and bolts of solar panel manufacturers, installation, and other types of renewable energy. It's called, Home Power Magazine. We have a home that has been powered by the wind and sun for the last 0 years or so, and most of our initial information came from Home Power, and afterward, from many of the sources that they have in their articles. Every few issures, they take an item connected to renewable energy, such as an inverter, wind turbine, water turbine, or solar panel, and list all the different models that are available. They are broken down by manufacturer, and include specifications like power output, range of voltages, efficiency, materials, and even where they are manufactured. If you subscribe online for one year, the cost is around $25 USD, you will have access to all the previous issues that are archived on their website. You can use their search engine to locate an article listing all the solar panels, they did one a year or so ago with all the information you are looking for. Despite what you might be hearing, solar power usage is growing at an incredible rate. In the US alone, there are over 00,000 homes and businesses operating some level of solar power right now, that's good news. As far as different countries using different requirements, most all of the manufacturers today are selling their products to most countries worldwide, they are designed to meet requirements for almost anyplace you might use them. Check the magazine out today, you might learn more than you were originally looking for. I will include their link below, and some other good sources for information. You can google any one of them to find their website. Good luck, and take care...Rudydoo
Q: What is the typical warranty period for solar panels?
The typical warranty period for solar panels is around 25 to 30 years.
Q: My family moved into a house that came with solar power panels but they are not connected and don't really understand how to even begin.
You need to know some electrical basics. You need to check if they are still working and determine the output voltage with the use of testers. They are just part of a system that includes other equipments as well like a controller, car batteries, inverters, diodes.
