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 solar panels be installed on greenhouses?
- Yes, solar panels can be installed on greenhouses. In fact, it is a popular practice as it allows for the generation of renewable energy while utilizing the available space on the greenhouse roof. The solar panels can help offset the energy needs of the greenhouse and contribute to a more sustainable and environmentally-friendly operation.
- 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:Interested in buying solar panels to save on electric bill.Any government help plans?
- I live in Ohio so I'm not sure if this is nationwide, but in Ohio there are grants you can apply for if you're investing in alternative energy for your house. I would look into those grants if they're available in your area.
- Q:What is the impact of hailstorms on solar panels?
- Hailstorms can potentially cause damage to solar panels, particularly if the hailstones are large and the panels are not adequately protected. The impact can range from minor scratches and dents, which may not affect the overall performance of the panels, to more severe damage that can impair their functionality. However, advancements in technology and the use of durable materials have made modern solar panels more resistant to hail damage. Proper installation and maintenance, including the use of protective measures like tempered glass or hail guards, can further minimize the impact of hailstorms on solar panels.
- Q:I want to put a solar panel(s) on my roof. What components do I need besides the solar panels? solar power controller? wires? How do I hook it into my home's electrical system and about how much electricity could I generate and save? Would the panels pay for themselves over time? Any help will be appreciated. Thank you!
- Solar water heating panels are often heavy, depending on their design. Solar electric panels are rarely heavy - at mabye 3 lbs. per square foot, including mounting racks, they are not much heavier than typical roofing materials. Whether the panels pay for themselves is a highly individualized answer, dependent on your state and local rebates (if any), how much sun your area gets, and the cost of your electricity. Just about any Californian can break even, but it can take 5-20 years. Prices are dropping, so this should get better next year (but federal tax credits expire - could be renewed, a Democratic president would be unlikely to veto). A house that is conservative in electrical usage (this usually means no air conditioners in the summer or electric heat in the winter) generally has enough roof area to supply 00% of its electrical needs. We have 0% of our roof dedicated to panels, and it supplies essentially 00% for us. The best way to get answers to your questions is to ask a few solar companies to do a free analysis and quote on your house. You can always say no. If you're thinking of doing it yourself, that's possible, but not trivial. It's also possible that a professional could install it for less than you could if you bought the parts yourself and installed it yourself. We installed our own, but the experience is a little dated - from 2006. There's a video at the bottom of the page below, if you want to see what we did.
- Q:How do solar panels affect the overall resilience of a building?
- Solar panels can significantly enhance the overall resilience of a building. By harnessing renewable energy from the sun, solar panels provide a reliable and sustainable source of electricity, reducing the dependency on traditional power grids. This independence ensures that essential services, such as lighting, heating, and cooling, can still function during power outages. Additionally, solar panels contribute to energy savings, reducing long-term operational costs and making a building more financially resilient. Moreover, solar panels reduce carbon emissions, mitigating the impact of climate change and enhancing the building's resilience to environmental challenges.
- Q:I'm thinking of having solar panels to generate electricity. The drawbacks are that I'm afraid if it needs repair, I won't be able to find anyone. Also I'm afraid that the roof is not very accessible. If it is a new house, should the roof have a roof hatch? What can make the system not work?
- Modern solar electric panels rarely fail. Because of this, if you would be installing them over a roof that only has a few years left on it, it would be better to redo the roof, first. In the unlikely event that a panel needs to be changed, this can be done in 30 minutes or so, because the panels are mounted on racks, with everything simply plugging together. I have never personally seen a solar installation go bad, but from what I hear, the inverter (a box that goes in next to your electric service panel) is usually what burns out after 5 years, assuming the install was done right in the first place. If you were to call roofers to repair your roof, they would somehow be able to get to your roof, by ladders, or a special truck. Solar installers use the same kind of equipment. They won't have a problem getting up there. A solar electric system is actually a very straightforward thing. No matter who installs it, if there is a problem, another installer should be able to diagnose and fix it.
- Q:i was looking into making solar panels to reduce my electric bill, but i need to know how to actually hook it up.
- nowing what to do with unused renewable electricity is always a dilemma – hooking up to the grid has to be the preferred option. If your residential home is grid tied, i.e. connected the electricity grid as opposed to off-grid and you are using solar panels to generate electricity. Then it makes a lot of sense to hook your solar panels to the grid, because instead of losing the unused electricity or having to maintain a bank of deep cycle batteries, you simply feed it back to the grid. You feed electricity back to the grid via your electric meter which measures the electricity in Kilowatt per hour. This has the effect of reversing your meter which in turn reduces your electricity bills and if you are generating a lot of electricity you could find the utility company owing you money! The Solar Powered System Therefore, your solar powered installation would look like this. The solar panel will connect to an “array disconnect” – you need an array disconnect for system maintenance because it allows you to easily shut off the power. The array disconnect is connected to an “inverter”. The solar panel generates DC power and the electricity from the grid is AC power. Therefore, you need an inverter to convert DC power to AC power. The inverter is connected to an “AC breaker panel”. This is the interface where your solar generated electricity meets the electric meter and allows you to feed electricity back to the grid. Now in most countries and states you are not allowed to tamper with the electric meter so at this point you should contact your local electricity energy supplier and ask them to supply an engineer to hook you up to the grid. If you have anything to add to this article or you have connected your system to the grid – tell us how you did it by writing a comment below.
- Q:solar panels or light parts
- They make lights that have solar panels built into them. Due to the solar cell, they can sense when it gets dark and thus switch on the light automatically. Look at Northern Tool or Harbor Freight web sites for ideas.
- Q:they are pretty expensive. So does it save you money on electricity in the long run? How easy is it to connect solar panels to your house?
- Yes I have. We have a little Labrador on the front steps(you know, a thing to hide keys under.) In his mouth is a little lantern that absorbs the solar energy from the panels and it turns on at night. Really saves you money, much more than regular electricity. The bill won't be so high this way, oh, and it's also good for the environment????
