Q:How do solar panels affect the environment?

Solar panels have a positive impact on the environment as they generate clean energy from the sun, reducing the reliance on fossil fuels and significantly lowering greenhouse gas emissions. Additionally, solar panels do not produce air or water pollution during operation, and their use helps conserve water resources. However, the manufacturing process and disposal of solar panels do have some environmental impacts, such as the use of certain chemicals and materials. Overall, the benefits of solar panels far outweigh their minimal negative effects.

Q:Me and my friend have made our own functional solar panels for considerably less than retail prices and we are thinking about selling them. Are there any legal issues regarding this? Would I need any special licenses or anything? Would using brand name components or parts in the panels make any difference legally? I want to know before I just go out and start doing it. Thanks!

you might first patent the design . Make sure everything is well documented . talk to patent agents and lawyers . Then instead of becoming a seller , introduce your design to established companies. They already have all the licences , lawyers, codes..etc to sell , install, advertise to buyers . they can often make you a partner or buy your design for a lump sum . Solar is a huge step . Best wishes

Q:How do solar panels impact the electrical grid?

Solar panels impact the electrical grid by providing renewable and clean energy, reducing the dependency on fossil fuels. They contribute to a more balanced and sustainable energy mix, lowering carbon emissions and promoting energy independence. However, their intermittent nature can pose challenges in grid integration and stability, requiring efficient energy storage and grid management solutions.

Q:Just wondering if it is possible to recycle solar panels and where that would be done. If it is possible, is there a money refund in return. Or would it be better to just take the metal off and get a refund in that way? Looking for basically any answer here.

It looks like you can. Although, I haven't been able to find like a drop off location or anything like that. Here's two phone numbers if you want to ask them. It's Sunday, and I'm assuming they're closed, otherwise I'd just call for you. San Diego (69) 562-783 or Berkeley (50) 843-3. It's a company called Borrego Solar. They look like a BIG solar company that specializes in commercial, residential and public sector turnkey, grid–connected solar electric systems. With over 25 years of experience. They sound like they would know about recycling, and at least be able to give you more information. I think because it's such a specialized item that is being recycled, there aren't going to be many options/drop off locations. Which ever option you choose (disassemble, or recycle as a whole) might depend on if you're looking to save the environment or make a buck. I got some information from the first link below, and the second link is to that Borrego company.

Q:I was wondering if they create other forms of energy besides electrical that is unwanted. Like heat due to the friction of something, or sound. Also why is a solar panel not able to collect 00% of the energy that is striking its panels. And how could the efficiency of this be hypothetically improved.

figure it out for us

Q:how the energy of load connected to solar PV measure.?Want too the basic idea about it.The role of current flowing thrugh the load?Can u explain with example..can explain simply?Im not an electrical student so explain very basics

A solar panel is made up of solar cells. Each cell produces about 0.5 to 0.6 volts. Cells are connected in series, like the batteries in a flashlight. Enough cells are placed in series to produce the desired voltage. Cells produce very little current, so many strings of cells are connected in parallel to produce sufficient current. The output is direct current (DC), like that from a battery. A home solar system needs alternating current (AC), so an inverter is used to change from DC to AC. Some systems have batteries for backup power. In these some of the DC output is used to keep the batteries charged. Systems are measured in kilowatts. System sizes are chosen to meet the demands for electricity. My system has a 6 kilowatt (kW) rating. The true output is more like 4. Now that you know this much you can Google SOLAR SYSTEMS to learn more.

Q:Do they really save energy? Cut or almost eliminate your electricity bill, if so, how much?Do they have a reserve unit to save electricity that I don't use, to use when the sun is not out?Can it produce enough electricity to cool a house and keep lights and appliances runningLastly, how much are the panels are running for.

You need an expert to tell you what the best solar panels are, in any case there is a gigantic outlay initially, each solar panel when I bought mine was around $ 600. I only had the two for my caravan, along with two heavy duty deep cycle batteries, they are able to discharge very low without damage to them, I have a small inverter which gives me 000 watts pure sine wave 240 volt. With my small set up I can use a micro wave oven and bread making machine as well as running power tools radio and television. Lighting can be efficient on ordinary 2 volt dc.They are far better than wind power I have tried that as a back up but I found it a waste of time and money most of the time. If you are connected to the mains power any power you don't use can be sold to the power supplier. With the really serious set up you can do anything with your power that you can do with the power suppliers. I set this of mine up to get away from the petrol generaters, I have had my panels for about 5 years and they are putting out the same wattage that they were when I bought them. I have not gone in for it seriously but I was told by someone that their mother had set up a system for $4,OOO and she received a grant of the same amount from the government and she sold her surplus power to the local power supplier. Incidentally I live in Western Australia.

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: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 .
