i need how a solar panel works, if possible make as easy to understand as possible like because of this , this happens and if you could please put a web source you got it from
Sunlight (photons) hit a piece of silicon and knock electrons out of it. That causes a flow of electrons, which is electrical current. simple enough? a better explanation from wikipedia: A solar cell is a device that converts the energy of sunlight directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight such as solar panels and solar cells, while the term photovoltaic cell is used when the light source is unspecified.
Solar panels have a positive impact on the environment as they produce clean and renewable energy, reducing the need for fossil fuels. They help decrease greenhouse gas emissions, air pollution, and water usage associated with traditional energy sources. However, the production and disposal of solar panels can have some environmental impact, including the use of certain materials and energy during manufacturing. Overall, their benefits outweigh the potential drawbacks.
So my buddy and I have an idea to start a small Solar Installation business. Small as in I am only willing to do one weekend a month and two weeks a year(I know it sounds like the reserves). These are my specific question:) What is the average cost in the U.S. to have Solar Panels installed?2) What is the average cost in the state of Hawaii to install Solar Panels?3)Is this a worth while venture? (There's a good chance i'm going to ignore this one anyways LOL!)4)How long does it take to install a photovoltaic solar panel?5)How long does it take to install a hot water solar panel?6)Besides the obvious, what permits are needed to get our start?7)What education or Cert. is needed?8)Average time to start up?If there is any other information you believe pertinent to this subject that I didn't ask directly, please share. Thank you for your help in advance!
The North American Board of Certified Energy Practitioners (NABCEP) is the “gold standard” for PV and solar heating installation certification. Cost vary on the size and difficulty of the project. The price of the panels are dropping and technology is getting better. A rough rule of thumb estimate would be $3 per watt for all the hardware and then double that to cover labor and overhead (insurance, permits, gas for the truck etc) Solar thermal has a faster payback than PV. The panels themselves go up fairly quickly. Installing roof mount attachments can take some time. This is also one of the points of liability. If done improperly the roof may leak and cause more damage than the profits on that job could pay for. There are a number of kits and pre-bundled packages available. You might try installing one of those on a friendly first. Make it a weekend project for yourself or on a friend or relatives house.
I was trying to figure out if I could run an electric heater off of a solar panel, but I don't understand these electric convertion factors and stuff. Would it work? (I know it'll only work in the daytime and stuff.)SOLAR PANELPeak Power 95W PTC Watts 73.0WVoc 30.7VPeak Voltage 24.4VIsc 8.6APeak Current 7.96A HEATERInput: 20 V/60 Hz ,500 W/5,200 BTU
the panel would have to be on for 0 hours in the sun to get an hours use with the set up. try researching solar hot water heaters. they are much more efficient. a cheap one would be painting an old hot water heater black and pipe it to the new hot water heater. it will save you 80% of your electric hot water bill.
Yes, solar panels can be installed on schools or educational campuses. In fact, many educational institutions are increasingly adopting solar energy as a sustainable and cost-effective solution to meet their power needs. Installing solar panels on schools not only reduces electricity costs but also serves as an educational tool, allowing students to learn about renewable energy and environmental sustainability firsthand.
I need to find a way to clean solar panels that automated, at best;A way beside using a large 'squeegee'

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 .
Yes, solar panels can power an entire house. The number of panels required depends on the energy needs of the house, the location, and the efficiency of the panels. However, with the right setup and sufficient sunlight, solar panels can generate enough electricity to meet the power demands of a household.
