- Q: How do solar panels affect home resale value?
- Solar panels can increase the resale value of a home due to their potential cost savings and environmental benefits. Studies have shown that homes equipped with solar panels tend to sell faster and at higher prices compared to similar properties without solar installations.
- Q: How do solar panels affect the property's energy consumption?
- Solar panels can significantly reduce a property's energy consumption by generating clean and renewable electricity directly from the sun. These panels convert sunlight into usable energy, which can power various appliances and systems within the property, thereby reducing the reliance on traditional energy sources and lowering electricity bills.
- Q: I live in Sacramento, CA, and I need some solar panels for a project fo school. They don't have to be very big......just something that I can use as an example.Thanks!
- Trees, they have plenty of leaves. You'll probably have to buy an educational kit from Radio Shack or something like that. Maybe break some old solar powered calculators open.
- Q: Got a quote for about $K today for solar panels to save me about $00 a month on my electric bill. I was just wondering if anyone had successfully bought and installed their own and how it worked for you?
- i have always been interested in it but the storage (batteries) and power grid tie in (to get paid for excess) technicalities made me shy away. since your getting it installed im sure labor is a huge part of that -OKorder has tons of the equipment. I think wind may be a good home renewable source depending on where you live (cheaper than solar if you got the wind and space) I would doubly check any goverment offerings - I know they used to and maybe still do offer sizable credits if you are within the bureacratic standards so make sure the installers work with you on that. good luck -its new - and going to be a hassle to get right but the world needs more like you. willing to pay more now for a better tommorow (and not just $ wise) you should come out ahead as interest rates and market provides little value on that cash and saving any equipment falure you sound good. does the price include the batteries for all your produce kwh's? panels and labor aside batteries are the next big one
- Q: What are the maintenance requirements for solar panels?
- The maintenance requirements for solar panels typically include regular cleaning to remove dirt and debris, checking for any damage or wear, ensuring proper electrical connections, and monitoring the performance of the panels. Additionally, it may be necessary to trim nearby trees or vegetation that could block sunlight and reduce the efficiency of the panels. Overall, proper maintenance helps to maximize the lifespan and efficiency of solar panels.
- Q: I thought that I had a fairly good understanding of watt's law, but i'm starting to doubt myself.If I have a load of 4500watts at 240 volts, how many watts of solar panels do I need, if the solar panels are at 2v?Yes, Yes... I have a charge controller, batteries, etc...So the way I looked at this at first:watts = volts * amps For the load4500 = 240 * xx would be 8.75aFor the power source (each solar panel)00 = 2 * xx would be 8.3a8.75 / 8.3 = 2.25, rounded up = 3So... based on that I came to the conclusion that I needed 3 solar panels...But... then I was thinking. Does it work that way?Or do I need 4500 / 00 = 45, aka 45 solar panels?In other words...If I have a 2v power source, how many watts do I need to drive a load of 4500w at 240v?ThanksMatt
- The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.
- Q: I riped two solar panels out of some solar light and tested them. I found out that they both produce 2 volts(I have no idea on the watts or amps). Iquot;ve hooked them up to an electric motor that can be driven by a AA battery, but when I hook the solar panels up to them nothing happens. What is wrong?
- Mark G has a good answer. If you leave your voltmeter on the solar cells when you hook up the motor, you will see the voltage drop to near zero. Same thing would happen if you tried to use 2 9 volt batteries to start your car. They just cant maintain the voltage when high curent demands are made.
- Q: i need someone to advice me which solar panels to buy.i have looked into few companies and i need some more info before decidingthe companies i checked were Sun tech trina solar Canadian solar and LDK solar.whice company should i pick?? please help.
- Selecting the right solar panels is like shopping for a car. Shop around and compare prices. Make sure the frame material will not rust or corrode away after a few years if you are near the ocean. Talk to satisfied customers is always wise. Get the guarantee in writing.
- 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 installed on a stadium or sports arena?
- Yes, solar panels can be installed on a stadium or sports arena. In fact, many stadiums and sports arenas around the world have already embraced solar energy by installing solar panels on their rooftops or parking lots. These panels generate clean and renewable energy, helping the facility reduce its carbon footprint and save on electricity costs. Additionally, solar panels on stadiums can also serve as a visible symbol of sustainability, inspiring others to adopt renewable energy solutions.
