- Q: solar panel capacity, how do it work
- Solar panels are made of solar cells.Solar cells are mainly made of a semiconductor called silicon,when sunshine on it,solar energy is converted into electrical energy by photovoltaic.The energy knocks electrons loose, allowing them to flow freely.This flow of electrons is a current, this current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce.
- Q: Can solar panels be used to power a public transportation system?
- Yes, solar panels can be used to power a public transportation system. By installing solar panels on the roofs of public transportation vehicles or at transportation hubs, the energy generated can be used to charge electric buses or trains. This reduces reliance on fossil fuels and helps to create a more sustainable and environmentally friendly transportation system.
- Q: During the summer my house uses about .47 kw/h I am wondering what solar panel do I need to cover most or all the electric bill. A link would be helpful too :)
- Are you saying your house continuously draws about .5 kW average all day long? That's 36 kWh per day, if so. This is about double what our house uses year-round, so if you lived in our area, that would be a 6 kW system. The only way to nail down a good number is to get a quote from a local solar installer, though.
- Q: I need to use solar panels to charge lead acid batteries in an off-grid application. I understand that solar panels have a open circuit maximum voltage and an maximum amperage under no resistance, and that one can optimize the power output by regulating the load (resistance). If so, is just connecting 2 -volt solar panels to a lead-acid battery inefficient? Are there devices that will maximize 2 volt output power (by varying the resistance)? Am I on the right track here? Thanks for any help.
- Hi, okorder / having good batteries like this one make save you the hassel to buy controllers. You can control your own charge buy different tips
- Q: who has solar panels on their home and are they worth it
- There are different kinds of solar panels. The biggest division is between photovoltaic panels that produce electricity and thermal solar panels that produce heat for hot water and space heating. Commercial photovoltaic panels are from 8 to 24% efficient while solar thermal panels are from 60 to 80% efficient. Solar thermal panels especially for hot water have a much higher ROI (return on investment) than photovoltaic panels. A solar hot water system may have a payback period (when savings equal the investment) as short as 3 to 5 years while photovoltaic panels will typically have a payback period between 7 and 5 years. Solar panels especially in times of low interest rates may be a very worthwhile investment with a better return than you can find almost anywhere else. But they are also highly dependent upon your situation. Owning a home with a good southern exposure is a prerequisite.
- Q: Can solar panels be installed on rooftop gardens or green roofs?
- Yes, solar panels can be installed on rooftop gardens or green roofs. In fact, these types of roofs provide an ideal space for solar panel installation as they often have ample sunlight exposure and can help optimize energy efficiency of the building. Additionally, solar panels on rooftop gardens or green roofs can contribute to a more sustainable and eco-friendly environment by combining renewable energy generation with green infrastructure.
- 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 we cover up solar panels on our house with regular siding?
- oh my goodness. make the investment aand update them
- Q: I was having a discussion with a friends about solar panels.He says that if there is a solar panel (sp) on the ground and a solar panel (sp2) high in the atmosphere (in the stratosphere) the difference in power output between sp and sp2 negligible. I said that there would be a large difference in power output because sp has all of the atmosphere to block the suns rays and sp2 has very little atmosphere because it is very high up (in the stratosphere) therefore more sun can get to the panel and more power is produced.who is correct? many thanks in advance, please leave sources if possible, for validity.

- Q: I want to put a solar panel(s) on my roof. What components do I need besides the solar panels? solar power controller? wires? How do I hook it into my home's electrical system and about how much electricity could I generate and save? Would the panels pay for themselves over time? Any help will be appreciated. Thank you!
- The first thing that you have to realize is that solar panels only make DC currant. This is used to charge batteries which when hooked to an inverter will make 20 v. AC. You need a large bank of batteries and a heavy duty inverter to power your house. There is also an automatic switch that will send power back to the utility company when you have excess power available. This is not a small project. Really think this out before you invest a lot of money for nothing.
