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:I had installed over the summer a solar panel system on my house. Hers some infofor you: I live in MOThe system cost 25K (Rounded numbers)The Rebate from the utility company was about 0KThe expected tax rebate will be about 5KI have a home office from which I work and is 5% of my homes sq footage. My question is though I am getting a basic tax rebate, should I be able to claim part of this off as an expense for my home office?It seams logical since I used to deduct part of my electric bill and I there for should be able to write off part of this. I am, after all using electricity and getting a bill from the utility that is higher than it would be if I didn't have the office2. If so which amount should it be? The full 25K or something after the rebates.: 5% of the Net Cost (After Rebates) Depreciated over 27.5 years. EDIT: Oops ....39 years. I was actually debated that in my head before I posted.

Q:I have a shed that has wiring run for light bulb and a couple outlets. It is in a dark corner of my yard and at night is kinda creepy to go in with even a flashlight. I am weighing the option/expense of running electricity from the house on an overhead line versus putting up a 45 watt solar panel on the metal roof with inverter, battery etc. Sunlight is good to excellent at the location. Question is - will this be sufficient for the occasional use of light and an outlet? What can I expect? Pros and cons appreciated: Lets say, for a simple approximation, that the 45 watt panel produces 45 watts /3 of the time and nothing the rest of the time. Each day, this will produce 8 hours times 45 watts = 360 watt hours. Also assume the battery charge controller and inverter waste half of that power, leaving 80 watt hours per day. If you use compact fluorescent lamps, that would allow you to burn 80 watts worth for an hour every day, or 90 watts for 2 hours, etc. That is a lot of light for a shed. You might consider using much less efficient tungsten filament lamps, but eliminate the inverter and choose low voltage (automotive) lamps that can run directly across the battery and lower the total cost, but give you only about half the light times time. The main advantage of the inverter might be that it would allow you to use small power tools or appliances in the shed. -- Regards, John Popelish

Q:I am thinking of buying a 3w solar panel called the nomad 3 from goal zero. I want to charge 35Wh lithum batteries. I have heard that lithium batteries are temperatmental and without a regulated current things could get ugly.I have a couple of chargers that came with the batteries. One is a 2v car charger and another is 0-240v wall charger.Goal zero sell something called a sherpa 50, which contains rechargeable batteries and an inverster and I think they suggest that I charge my batteries indirectly through the Sherpa 50, however, the sherpa 50 is expensive at $200, and seems to have a small capacity, in addition to being extra weight that i don`t want to carry.Electronics geniuses, you are my only hope.: Lithium batteries do have special charging requirements. I would recommend that you use the 2 volt charger that came with them to keep them happy. Automotive power systems can have voltages as high as 4.5 volts when the engine is running so there's no need to limit the output of the panel to anything less than that. Check with the charger manufacturer to see what it will withstand. Some will work with systems up to 24 volts nominal (up to 29 volts actual) found in larger commercial vehicles such as trucks and busses. If your charger will work with both 2 and 24 volt systems you might not need anything extra to use the unregulated output of the panel. Otherwise I'd recommend a shunt regulator to clamp the output of the panel to no more than 4.5 volts. That way it would dissipate (waste) very little of the panel's power, and even that would only be during those rare times when the panel is producing maximum output. Such a device could be as simple as a high power zener diode, a low power zener coupled with a power transistor, or a precision shunt regulator such as a TL43 coupled with a power transistor. A more complex way would be a to use buck/boost regulator between the panel and your charger. You might gain a slight advantage under low light conditions when the panel isn't putting out much but the overall efficiency could end up worse than the simpler shunt regulator. Under optimum conditions, I would expect it to take a full day for a 3 watt (peak) panel to charge just one of your 35 Wh batteries. Charging an intermediate device such as the Sherpa 50 through its built in charger and then using it to charge your battery through yet another charger would severely cut your overall efficiency. Depending on how long you'll be gone, it might be far more practical, reliable, and economical to just carry (or find a way to be resupplied with) a few additional fully charged 35 Wh batteries. Don

Q:Ok so I am planning on buying a solar panel. I am doing it to possibly sell the energy that it stores. It is a 20 watt panel so I am just wondering if every week or month if I sold that energy that it stored would make me a good profit. I am not hoping for thousands of dollars a month..just like 00? The solar panel cost me $,00 so if so, how long do you think it would take to make good profit. Also, how much would I make every week or month?: I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel /solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.

Q:Can solar panels be used in areas with limited sunlight?: Yes, solar panels can still be used in areas with limited sunlight. While solar panels are most efficient in direct sunlight, they can still generate electricity even in areas with less sunlight. The panels can capture diffuse sunlight and convert it into usable energy. However, the overall energy output may be lower compared to areas with abundant sunlight. Additionally, advancements in solar technology and the use of more efficient panels can further enhance their performance in areas with limited sunlight.

Q:China is the world's biggest producer of solar panels: Go ahead admit it...Carter was right ! He was right in seeking to raise the fleet auto mileage standard to 48 miles per gallon by 995. (Even U.S. automakers admitted at the time that they could easily achieve 30 mpg by 985.) Carter was right in exhorting Americans to turn down their thermostats, even if he did look nerdy in a cardigan while urging us to do so. He was right to encourage fuel conservation by proposing a 50-cents-per-gallon tax on gasoline and a fee on imported oil —- in effect, a floor for fuel prices. Invoking the pioneering spirit of the 960s moon mission, he was right to recommend a tax on windfall oil profits to finance a crash program to develop affordable synthetic fuels. Carter was correct, too, in setting a goal of obtaining 20 percent of our energy from solar power by the year 2000. The solar panels Carter put up on the Whitehouse were USA made. The solar

Q:How can I start working as a solar panel installer/technician without years of education?: The best suggestion I can give is to call solar installation companies in your area, and ask for their recommendation as to what to do. They may recommend a technical college with an appropriate program. With unemployment rising, new jobs in solar will likely be scarce for a while. You might also inquire at roofing companies. If you apply at a solar company, and can demonstrate that you already have roofing experience, that will be a plus.

Q:Do solar panels work at night?: No, solar panels do not work at night as they rely on sunlight to generate electricity.

Q:Can solar panels be installed on forests or protected areas?: Solar panels can be installed on forests or protected areas, but it is important to carefully consider the potential environmental impact and sustainability of such installations. Proper planning and assessment should be conducted to determine the potential disturbance to ecosystems, wildlife habitats, and biodiversity. In some cases, it may be more appropriate to explore alternative locations or prioritize the use of existing infrastructure for solar panel installations.

Q:Can solar panels be used to power swimming pools or hot tubs?: Yes, solar panels can be used to power swimming pools or hot tubs. Solar energy can be harnessed through solar panels and converted into electricity to operate the pumps, heaters, and other equipment required to maintain the desired temperature and cleanliness of the water in swimming pools or hot tubs.
