Q: what is a solar panel?: A solar panel is essentially a battery charger that transforms sunlight into an electrical DC (direct current)charge.

Q: How much electricity does a solar panel produce?: The amount of electricity a solar panel produces depends on several factors, including the size of the panel, its efficiency, the amount of sunlight it receives, and its location. On average, a standard residential solar panel can produce anywhere from 250 to 400 watts of electricity per hour under optimal conditions.

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: I've been reading up on Solar panels because I think in the long run this would be beneficial in the long run. My Dad had looked into it before passing and had said it was too expensive. How much does it range for getting them placed on the roof and how exactly does that work? I think I remember being told that PGE has incentives and could possibly even end up paying you for having it? What does having panels cover? I know electricity but does it also heat things up? Sorry I'm kinda dee dee dee on this lol. Any and all information would be greatly appreciated. If anyone has solar panels can I get your experiences with them? Thanks!!: There's a few different kinds of solar panels. Some of them are only for collecting heat, they're relatively inexpensive and not a bad deal, though installation can be expensive of course. The most sophisticated of these use some pretty high tech collectors to heat up an antifreeze solution that in turn is circulated through a reservoir (how water heater), to supply the house. Your electric producing solar panels are more expensive. You can go on OKorder and do a search on photovoltaic panels and get a pretty good idea real quick. The panels alone can run you 2 or 3 bucks a watt of output or more, and you may need 3 or 4 thousand watts of output to give you reasonable system for your house, depending on how much electricity you use. Then there's installation, for which you may need a professional electrician and so on. If you want a system incorporating deep cycle batteries then that's another expense, but you don't necessarily need those if you're not planning to take yourself completely off the grid. Not that the systems are really complicated. Some people wire panels together themselves from scrap cell components to save money. Of course you'd need to understand the basic wiring involved for that, and you'd almost certainly be required to retain an electrician to tie any system into the grid itself. Although there is such a thing as a plug in grid tie inverter. This is is a gadget that will take your DC solar panel output and feed it into the standard wiring of your house via an ordinary electrical outlet. You'd still need to understand enough to get the DC voltage right no doubt.

Q: Can solar panels be installed on swimming pool covers?: Yes, solar panels can be installed on swimming pool covers. This innovative approach helps harness the sun's energy to power pool equipment and reduce energy costs. The panels are typically lightweight and waterproof, making them suitable for installation on pool covers.

Q: We've been considering solar panels for a while now, and we'd like to know a little more about them. Please answer to the best of your knowledge. Thanks.: It is definitely worth doing your homework to evaluate how much you electricity you want to obtain, what you location will allow, and the availability of state and federal tax credits. I suggest reading about it in a book or e-book. Check out the referenced source on solar calculator for cost and size detailed information, it's fun and informative.

Q: I need help?!!: It needs some battery banks in order to store the energy that will be useful during nighttime if less energy is stored in the batteries due to poor weather condition the effectivity of it is minimized. It has some limitations like you need more batteries in parralell to store more energy from solar cells, and it needs to be fully recharge the next day after it is discharged at night.

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: Are solar panels affected by shade?: Yes, solar panels are affected by shade. Shading can significantly reduce the efficiency and overall energy production of solar panels. It is important to ensure that solar panels are installed in areas with minimal shade to maximize their performance.

Q: Can solar panels be used for powering agricultural irrigation systems?: Yes, solar panels can be used to power agricultural irrigation systems. Solar energy can be harnessed to generate electricity, which can then be used to power pumps and other equipment required for irrigation. This can be a cost-effective and sustainable solution for farmers, especially in areas with abundant sunlight.
