- Q: Can solar panels be installed on a barn or shed?
- Yes, solar panels can be installed on a barn or shed. In fact, barns and sheds are often great locations for installing solar panels as they typically offer ample roof space and are often in areas with good sun exposure. Installing solar panels on a barn or shed can help generate clean, renewable energy and potentially offset electricity costs for the building.
- Q: Do solar panels require maintenance?
- Yes, solar panels do require maintenance. Regular cleaning to remove dirt, dust, and debris is necessary to ensure optimal efficiency. Additionally, periodic inspections and maintenance checks are recommended to identify and address any potential issues such as loose connections, wiring problems, or shading that may affect performance. However, compared to other forms of energy generation, solar panels require relatively low maintenance efforts.

- Q: I would like to know if I had a mobile kitchen could I power it from solar panels mounted atop the vehicle (truck).(to power electric kitchen equipment, i.e. stove, deep fryer.), instead of propane…could I possibly connect the solar panels to a battery to save my generated electricity? If solar panels would not be enough power could a small windmill suffice…?
- The best way to find out is to determine the wattage of each piece of equipment you want to use and how many hours you want to use those pieces of equipment. Finally, calculate the total number of Watt-Hours you need at minimum. Then you need to research solar panels or mobile wind mills (they need to be pretty huge to get a decent amount of energy I think, so solar power is probably the way to go). You will need to figure out the efficiency of the solar panels, the size of the array, how you will turn it or if you will turn it at all (to face the sun to get the maximum energy input, or maybe to use mirrors so you don't have to turn it. Once you find a good configuration for your mobile kitchen, you need to calculate if the Watt-Hours you will generate on an average day (with average weather) is enough to power the equipment whose energy requirements you previously calculated. Then you have to keep in mind that some days will have no sun, and you may not be working on some days, but you can still capture sunlight. For each case, a large battery array will be required. If you had a guage on that array, you could also hook it up to the a small generator in case you need immediate power. It's an eco-friendly process, but the initial cost is high and it requires a lot of research and planning. This is why most people do not do it--not because they don't want free energy from the sun, but because it's not easy to start collecting that energy in an efficient way. Sorry I couldn't give you more specific numbers, but a solar panel sales agency should be able to estimate whether or not you could do it (they'd probably set it all up for you too). ^_^
- Q: Is it really necessary to make solar panels that expensive?
- it cost less then $000. to make a car if you add all the cost of the material the average car made in the USA is sold for 30,000. before the company make a profit they need to sell 6 cars to pay for the labor. With a solar panel system it cost depending on you kilowatt use then they figure out the life expectancy of the unit what your monthly ele bill would be and that is what it cost for your system and that is with out the carrier charge from your power company who charge you for both when you use or sell power to the grid and most of the systems sold are sold to tie into the grid. as far as how much does it cost to make a solar panel The reason they give the price per watt is that is how they charge to sell them The process is not as complicated as they make it The high cost is in the so called shortage in silicon they claim there is a shortage of the type of silicon used in making the chips but last I heard silicon is just sand and it is the eight most common element on the planet it is the same process used to make computer chips which you can by now for around a dozen for a penny put that does chips togethet and you have one of the around 00 chips in a solar panel so a solar panel costcost about fifty bucks to make solar panel 00 watt sells for around $50. for a starter kit they sell them 200 percent mark up minimum the big cost is in the installation .
- Q: how much energy does solar panels save you? (like a month, year, etc)
- It depends on the size of the solar panels and the intensity of the solar-light. So, there's difference in every place. It's impossible to answer unless there's detail of panel size, panel quantities, average rainfall, average solar days, etc.
- Q: I am doing a science fair project on solar panels, and I need four solar panels to conduct the experiment. I would only need the solar panels for a week. What type of solar panel should I get?
- Your USB power booster may be fragile and is likely expensive, so possibly you should get your 5 volts some other way. 3.7 volts plus a .2 volts D cell is 4.9 volts which is likely close enough for charging most anything with a USB charging cable. If bright sunlight is falling on your solar panel the battery voltage will go to about 5. volts charging at 700 MA, which is also likely acceptable, and will generally be less as part of the 700 ma is being used to charge something else. Also 300 ma may be more typical output of your solar panel even when the sun looks like it is bright. Over charging is unlikely unless the lithium cell has a lower amp-hour = AH rating than the Ni-cad (or nickel metal hydride NiMH 4 AH) D cell, but perhaps you should disconnect the solar panel, if it has been more than one bright sunny day since you charged something with a USB cable. If your battery reads over 5 volts with the solar panel unlighted or disconnected, you are likely to over charge either the lithium cell or the D cell. The PCB protected may complicate adding the D cell (probably not) so you may want to follow your original plan. Your solar panel may send as much as 9 volts to your PCB protection board, when the lithium cell does not need charging: Can the protection board tolerate 9 volts? Probably. If in doubt you can put either a .5 volt or .2 volt rechargeable D cell in series with the solar panel which reduces the input to your PCB protection by about .5 volts. That D cell will over charge, unless you replace it weekly, perhaps oftener. I think your PCB protection prevents over charging and cuts off the load if the lithium cell is discharged to an unsafe level or the load is demanding excessive current. Only the last is a possible problem = one of your USB cords may demand an amount of current that the PCB protection considers excessive. Your USB booster needs about twice as much current as the usb cord is supplying. You don't get the extra voltage by magic. Neil
- Q: what do solar panels do?
- Solar panels (arrays of photvoltaic cells) make use of renewable energy from the sun, and are a clean and environmentally sound means of collecting solar energy. Here at solar panel information, we've amassed a wealth of information relating to solar panels and the field of photovoltaic technology. You can learn how solar panels work, how they are manufactured, where to buy them, and how to set them up. If you are looking for information on solar panels and don't know where to start, check out our solar panels section to learn more about how these photovoltaic cells are derived from silicon and what solar energy means to you.
- Q: There are so many solar panels and kits it is very confusing. I need to know what exactly I would need if I had an underground home with no electricity. I want to be totally off the grid with solar power. Someone please explain to me in simple terms what exactly I need. Maybe give me a link to the right kit for me. Also are they easy to install? Are there instructions that I need to download?Thank you

- Q: i used 734 killowatts of power last month, any idea on how many solar panels i would need. What im looking for is to somehow hook up my central air to solar panels.
- Good answer above me. One other tip, look at your full year's usage. Last month, if it was cold, you probably didn't have your air conditioner on. Our house uses 500-600 kWh a month average, but we have no air conditioner. To generate all of this requires a 3 kW array in our part of California. That's only to give you an idea of what it takes - what you need will be based on how much sun your area gets, and what percentage of power you want to get from the array. If you pay tiered electric rates, it may make sense to displace only part of your electricity with solar. Or it may not make financial sense at all, if you have cheap electricity where you live. To get the best assessment of what kind of system would be appropriate, try to get one or two no-obligation quotes from local companies. You can always turn down the bids, but at least you will have learned what's involved and the approximate cost. If you want to see what we did with our house, please contact me through the email in my profile.
