- Q: I want to know how you can store energy using a solar panel. The energy stored needs to be stored so that a light or laptop charger can plug in to it.
- Batteries my man... but you will need a charge controller the silicon panel will produce dc and you will need an inverter for an ac light
- Q: I'm just geting into electonics and stuff. So I am trying to make a simple USB charger. I'm looking for at least 4 volts output. What I've got is two solar panels (detached) a 4 AA battery holder, and a circuit board with an led on it (took the solar panels out of old lawn lights. I need more charge out of my panels (I think) so I tried attaching them. I soldered the positive wire from one to the positive connection on the other and negative wire to negative connection. After doing so and checking the multimeter, it says I have no output at all. How do you connect them?
- You will need to wire several cells in series to obtain the necessary voltage, and you may need to wire several sets in parallel to obtain the required current. Series: Connect the + lead of one cell to the - lead of the next. You may chain any number of these together this way, and the output voltage will be the sum of the output voltages of each cell. The output current will be the greatest current of each individual cell. Parallel: Connect the + leads of each cell together, and the minus leads of each cell together. The output current will be the sum of the output currents of each cell. The Output voltage will be the greatest voltage of each individual cell. Picture this: think of the series cells as a column, connected from top to bottom. Think of the parallel cells as a row, with all the tops connected together and all the bottoms connected together. To arrive at the required voltage *and* current, you will need an array of cells, in rows and columns. The voltage will be the sum of each column, while the current will be the sum of each row. Most solar panels are arrays of individual cells. The arrays are then connected in the same fashion to provide the necessary combination of voltage and current.
- Q: Do solar panels require cleaning?
- Yes, solar panels do require cleaning. Over time, dust, dirt, leaves, bird droppings, and other debris can accumulate on the surface of solar panels, reducing their efficiency. Regular cleaning is recommended to ensure optimal performance and maximize energy generation.
- Q: Can solar panels be used in areas with high levels of chemical pollutants?
- Yes, solar panels can be used in areas with high levels of chemical pollutants. However, frequent maintenance and cleaning may be required to prevent the accumulation of pollutants on the panels, which could reduce their efficiency over time. Additionally, the presence of chemical pollutants in the air may have a negative impact on the overall performance and lifespan of the solar panels. Therefore, it is important to assess the specific conditions and potential risks before installing solar panels in such areas.
- Q: By best I mean safest places. If I were to install them on my roof am I risking due to damage from weathering? Such as rain or snow. I don't get very high winds around here, nor any natural disasters such as hurricanes or tornadoes. Does anyone have solar panels that have been durable for a long time? Is it worth the investment?
- Probably not worth it. Sure, it is a great idea, but it will take decades to get your money back in energy savings. Today's panels are fine for a roof. However, I'd worry a little about the interface (where leaks could occur) especially in a retrofit. They, of course, will need to face south.
- Q: About how much would it cost to purchase and install solar panels for the average American house so that the house can be off the power grid and use the same amount of electricity as it normally does?
- I had a survey of my home and it was estimated at $30K with a 30% rebate from the government. It would take about 5 years to pay back the cost. I elected to go solar water heating instead. 2 panels with piping installed to an 80 gallon electric water heater with an internal heat exchanger. One small photo voltaic panel to run the pump. There is ethylene glycol inside the pipe and it circulates and heats the water. Works excellent. I live in Nor-Cal and we get a lot of sun. I need to comment on another statement that photo voltaic cells cost more energy to produce they generate. Maybe once but not true any longer. {Solar cells and energy payback In the 990s, when silicon cells were twice as thick, efficiencies 30% lower than today and lifetimes shorter, it may well have cost more energy to make a cell than it could generate in a lifetime. The energy payback time of a modern photovoltaic module is anywhere from to 20 years (usually under five)[9] depending on the type and where it is used (see net energy gain). This means solar cells can be net energy producers, meaning they generate more energy over their lifetime than the energy expended in producing them}
- Q: Can solar panels be installed on remote or off-grid locations?
- Yes, solar panels can be installed on remote or off-grid locations. In fact, off-grid installations are quite common for solar panels as they can provide a reliable and sustainable source of electricity without the need for a connection to the traditional power grid. The advancements in solar technology and the availability of battery storage systems have made it possible to generate and store electricity in remote areas, making solar panels an excellent choice for powering isolated locations.
- Q: Is it as simple as buying the panels, an inverter and plugging it into a wall-socket, assuming it would just send power back into the outlet and supplement my house's electrical usage, or... Is it not that simple?Remember, I'm talking about a SMALL system, and I don't care how little power it'd make, or how uneconomical it would be.
- Earlier answers kind of answer it for you...but there are alternatives, that avoid the cross-pollination problem: install a 2Vdc auxiliary home system. Lights primarily, and perhaps a couple of low-draw devices. Motor/mobile home suppliers have a wide range of gear. Use Google to find suppliers. A battery 'bank' would be needed, and of course indoctrination of users to shed the 'power when you want it' life-style. Strict rationing, priority tasks, and so on. Supplement with LP heat/gas lights. 'Off the grid' sounds fun for camping, but as a life-style, it's a lot of work and planning.
- Q: Interested in buying solar panels to save on electric bill.Any government help plans?
- Check with your Power Company, ours has had several $$$ Incentive Programs that they get involved with,Federal,State,and Private Sector. Just about anything High efficiency or Electrical saving,including Solar.
- Q: i took some solar yard lights apart and put them together in a series. i was told if you take AMPS times VOLTS = WATTS. do you test it with ac volt or dc volts? I tested mine with dc volts and got 4 volts in good sun and had my meter set on Ma or milliamps and got .83 which i am asuming that is .83 of one amp now i took those and multiplied .83 times 4 volts to = 34.03 watts. Is this large enough to charge a car battery in a day? And doese it make a difference for amps on how fast it charges or watts. i also was looking around and found 30 watt panels but had higher amps. I am very interested in building solar panels but i realize i dont know what i need to do to make shur they are big enough. my panel is only 9inch by 0 inch. It seems weird that i am putting out 4 volts
- A equipment that super could have a max power production of around 2000 watts. i won't be able to declare if it fairly is sufficient to your desires via fact the figures you gave do no longer make experience. right here is why: the quantity of power being ate up at a given time is measured in watts--that's the ability point. To degree how lots electrical energy you utilize you utilize you need to use kilowatt-hours (or watt-hours, yet its greater handy to apply the former). So--in case you utilize a million kilowatt-hour, meaning you have been ingesting power at an favourite. fee of 000 watts (one kilowatt) for a million hour. Now, it may be VERY united statesa. for a house to apply 5,000 kilowatt-hours in a month--that's an exceptionally severe discern. Yor top power utilization could be 5,000 watts. A image voltaic panel equipment with a optimal technique of 2000 watts isn't adequate to power maximum residences. you easily want a minimum of two times that--and so lots greater in case you like to bypass off the grid. besides the shown fact that it must be an excellent investment besides. you are able to use very practically all the means advert that woudlld maximize your mark downs.
