- Q:I'm building a solar panel for the first time and have the tabbed solar cells. I put together 4 strings of 9 cells. And the cells are each 0.55V, 3.6A.Because I'm going to be using the panel indoors and leaning it up against a window pane, I put them in a 24x36 inch poster-size frame. The frame has a plexiglass cover and a thick cardboard backing. My question to you is this. Will the cardboard backing up against the metal underside (positive side) of the solar cells be ok? I don't know if it may catch fire or if holes may burn through when there's full sun.My guess here is it should be ok. But maybe I'm wrong. If I am wrong, or if something should be put in between, please let me know what I should use.Thanks everyone!
- In commercial panels some sort of polymer is often used for backing. With a 2V panel there are 36 cells, which means they can still output about 4V for charging a 2V battery even when hot. The voltage reduces about 2.2mV per degree C per cell. Commercial panels are meant to work up to about 60 degrees C, which is quite normal in the sun. I have found just lying them on the grass the air circulation is reduced, and they get too hot to charge a 2V battery. This means the backing should have good thermal conductivity while being an electrical insulator, as well as mechanical strength. The cells are often encapsulated in a thermosetting plastic first, then laid face down so a liquid polymer can be poured as backing.. I have removed commercial panels from their frames and re-packaged them to work in a very wet environment. I suppose cardboard would work, but it is unlikely to have good cooling so the expected voltage would be lower. As you intend to only operate indoors I suppose it is unlikely you have full sun most of the time anyway, so there could be less heating and less output current accordingly. I think the cardboard is only useful for a short time, and is not strong enough. Temperature wise it is marginal. The link below uses plywood for the backing. The backing is supposed to provide strength too. A sheet of some sort of plastic or laminate (including melamine laminate as in kitchen bench tops) comes to mind too. The cells are supposed to be bonded to the backing for better thermal conductivity. Use silicon RTV to stick cells to the backing, very thinly.
- Q:Can solar panels be installed on drones?
- Yes, solar panels can be installed on drones.
- Q:What is the most efficient solar panel, how many would we need to power the United States, and how much land would it take?
- I know that the US uses 500 Gigawatts (giga is 0 ^9). I think a solar panel meter square might generate at most 00W. So you would need 500E9/00 = 5 trillion of these. 5 trillion square meters is 70 kilometers on a side. Dont forget about night and clouds!
- Q:I was just wondering what the minimum and maximm charging voltage and ampere is for li ion batteries. If i connect a solar panel, which only gets enough sunshine to generate voltage, will that still charge the battery, or would i have to series connect solar panels until they together reach 3,7volt?
- One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .
- Q:Can solar panels be used in areas with high levels of saltwater exposure?
- Yes, solar panels can be used in areas with high levels of saltwater exposure. However, it is important to take certain precautions to prevent corrosion and maximize their performance. This can be achieved by using materials that are resistant to saltwater corrosion, such as stainless steel or aluminum frames, and encapsulating the solar cells with durable and protective coatings. Regular maintenance and cleaning can also help ensure the longevity and efficiency of solar panels in such environments.
- Q:Can solar panels be installed on a warehouse or storage facility?
- Yes, solar panels can be installed on a warehouse or storage facility. In fact, these types of buildings often have large, flat rooftops that are ideal for solar panel installation. Installing solar panels on warehouses or storage facilities can help generate clean and renewable energy, reduce electricity costs, and contribute to sustainability efforts.
- Q:Can solar panels be installed on agricultural or farming operations?
- Yes, solar panels can be installed on agricultural or farming operations. In fact, many farmers have been adopting solar energy as a sustainable and cost-effective solution to power their operations. Solar panels can be mounted on rooftops, open fields, or even integrated into structures like barns or greenhouses. By generating clean energy, farmers can reduce their reliance on traditional energy sources, lower operational costs, and contribute to a greener future.
- Q:i dont wanna buy a solar panel becuase its too exspensive, i dont want use technical stuff i want to use every day materiels, but i need to know asap plzzzz.
- well... I'm not sure how you can make a solar panel that you can store electricity off of. But a simple solar panel is... Take a pane of class a bunch of pop cans and a fan... color the bottoms of the pop cans black and attach them to a board of some sort (black side up) put the pane of glass over the cans (with about 5 inches of space between) and put the fan blowing away from the cans you can set this in a window that gets lots of sun and it will use the solar energy to heat your house (its pretty efficient and warm)
- Q:I am researching several solar panels to install in my house. I would like to use a 40 watt panel to connect, through a solar battery controller, to a battery or two. I would then like to use the solar panel (40 watts) to charge the battery(ies) for emergency use. Once charged, and when needed, I would like to use the battery(ies), 2 volt deep cycle, to power several LED lamps. Since I am new to solar power I had several questions...Is a 40 watt panel strong/large enough to charge a 2 volt deep cycle battery or two?How long would it take to charge one of these batteries?What would be the expected cost to purchase necessary supplies? (With the solar panel, battery controller, and MC4 cabling I've found I have an expected cost of roughly $00.00 with batteries)Would this be difficult for someone with little experience in this field?
- There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
- Q:What is the efficiency of solar panels?
- The efficiency of solar panels refers to their ability to convert sunlight into usable electricity. The efficiency can vary depending on the type and quality of the panels, but most modern solar panels have an efficiency of around 15% to 20%. However, advancements in technology have led to the development of highly efficient panels that can achieve efficiencies of up to 40%.
