- Q: I know that one LED can't power a solar panel. I have found 40 kmcd LED's on OKorder. I know that several of them (28 totale each one with a 470 ohm resistor all at 2 VDC) can show a reflection on a wall in daylight 60 feet away..
- The 40 kmcd rating is a measure of luminous intensity (how bright it looks), not a measure of output power of the visible light. We can estimate the performance of your proposed system as follows: The LEDs on OKorder each are rated about 20mA maximum at about 3.2V, or 64mW (milliwatts). If you use 470 ohm resistors connected to 2VDC, the current that will flow, per LED, will be about: (2V-3.2V)/470ohm = 0.0872A = 8.72mA The power taken from the 2VDC power source will be: P2v = 2V x 8.72mA = 224.6mW (per LED) The power input to each LED will be about: Pled = 3.2V x 8.72mA = 59.9mW (per LED) The LED has a luminous efficiency that can range from about 4.2% to 22%. This efficiency is the ratio of the amount of visible light output (in watts) divided by the input power (in watts). The OKorder listing doesn't identify the output power level (either in watts or in lumens), so let's assume a 0% efficiency. The LED output power will be about: Pout = 59.9mW x 0% = 5.99mW (per LED) A solar panel converts visible light to electrical energy with an efficiency that ranges say about 6% to 8%. Suppose the solar panel efficiency is 2%. Then the electrical power output by the panel will be about : Pe = 5.99mW x 2% = 0.72mW (per LED) If you shine 00 LEDs on the panel, the output electrical power will be 00 times that amount: Pe00 = 0.72mW/LED x 00 LED = 72mW <===ANSWER The power taken from your 2V source will be about: P2V00 = 224.6mW/LED x 00 LED = 22460mW = 22.46W The system efficiency will be about: Eff = solar output / battery input = Pe00 / P2V00 = 72mW / 22460mW x 00% = 0.32% SUMMARY: If you shine 00 of the LEDs on the panel, you will capture back about 0.32% of the energy expended, or regain about 72mW.
- Q: Can I add more solar panel let say up to 200 watt and adding two 2 volts battery using the same charges controller and power inverter?
- If you put a black panel on the ground or on your house and don't connect it to anything, it will absorb solar energy (heat) during daylight and release it at night (radiation). Not exactly. Assuming the black panel establishes an equilibrium temperature, it's going to be losing exactly as much heat as it's receiving during the day. Some will radiate out into space, some will conduct or convect into the atmosphere. As a wild guess, maybe 50/50. If you hook up a solar panel in the same place but hook it up to batteries, charge the batteries during sunlight hours and using that energy to electrically heat the home at night. The panels will absorb solar energy during the day but will convert that to electrical energy in the batteries instead of radiating it back into space at night. The panels are only about 4% efficient, so it's the same situation as the pure black panel for 86% of the energy. The remaining 4% will get stored in the batteries and then converted to heat at night. That heat will eventually leak out of the house and warm up the Earth a tiny bit. I think it's much the same situation either way. With the black panel the energy gets radiated / conducted/convected right away. With the solar panel a small percentage is stored and not so much is radiated, mostly conducted and convected. You're partly right as a black panel is going to radiate more into space than a house. But you're taking about maybe some day about 4% of % of the differening radiation/convection/conduction fraction, of the Earth's surface area. Probably not significant.
- Q: I want to install a solar panel system and our power grid can't work in reverse(so it get its electricity from us). My question is how do you prevent electricity from our panel to go to the grid without disconnecting the grid? How can we also use the grid and the panel at the same time when the panel are not creating enough power?PS dont say ask an electrician
- If you are grid-tied, then a standard solar electric system will always feed back into the grid if you are not utilizing more power in your home than is being generated by the solar panels and inverter system. It is possible that a grid isolation device designed to prevent direct back feeding is available, but haven't heard of one in common use. New laws in most areas of the US are now mandating that utilities allow grid-tied alternative energy systems. Double-check you local laws. Sometimes you can't take the utilities word for truth--most will automatically say 'no' and will only relent when you show up with the law in hand. Unfortunately, some utilities have figured out another way to shut down alternative energy pioneers--they demand multimillion dollar insurance policies covering damage that their equipment could sustain from your little PV system. Technically, they are still in compliance with the law, they just make it impossible for a homeowner to meet their requirements. If you are getting the runaround, go to your state representative for help. It's amazing how contrite those utility people can be when a state senator (or even US Senator) has just sent a letter asking them why they are stonewalling a law-abiding and well-meaning citizen. Good luck, and don't give up!
- Q: Is it really necessary to make solar panels that expensive?
- First Solar recently announced that their costs to produce panels dropped below $ per watt. I don't know how much of that is accounting tricks. Of course, that doesn't mean that they would sell panels for that price - any capitalistic company is expected to drive the price up to what the market will bear. Crystalline silicon panel producers are coming in at about $2.50/watt right now for the best of them. But again, the selling price is what the market will bear.
- Q: I have been thinking about getting solar panels for my house. What do you think I should get? Companies? Prices? I also have another question. How much energy can a small solar panel produce?
- The price of solar systems have dropped dramatically in the last 5 years. I would say it has reached to the point that it financially makes sense to go solar! An average home in [California] with $200 monthly electric bill would need a 7.25 kW system to offset 00% of their electric bill (means you won't have to pay anything to your utility company). Average price of the panels are anything between $2,500-3,500 per kW (after 30% Federal Tax credit which might expire at the end of 206). So, average system price will be $7,000-$25,000. If you wanna buy the system your loans monthly payments will be around $40-50 for 2 years and after that your system is paid off and you can enjoy free electricity! Total saving over 25 years can exceed $70,000. Regarding the selection of the right panels or the best company in your area, it varies case by case, city by city. Pick My Solar offers a free service to homeowners to choose the right fit for their home. It's like Expedia or Priceline for residential solar market.
- Q: can solar panels be on houses? malls?stores? WHAT ABOUT TRAINS?
- Solar panel is an alternative source of energy. Solar panels are like plants, they take energy from sunlight. Only in solar panels, electricity is produced instead of oxygen. This electricity is used to power homes just like cable electricity.
- Q: Are the solar panels on the roof just a gimik to get all the tree huggers to buy it, or are they actually a good, efficent design?
- treehuggers already want priuses. the solar panel is meant to run an electric ac system that cool's the prius if the car gets too hot inside. its nice, but personaly, i'd rather have it charge the battery.
- Q: Why does the new 200 Toyota Prius have solar panels at the top of the vehicle?
- Hi, the solar powered-venting system is not air conditioning, it is simply a venting system to attempt to balance the interior temperature of the Prius with the outside temp when the interior of the Prius is at least 68 degrees. This is an optional system and is available as a stand-alone option for $800.00 or $3600.00 in conjunction with the navigation system. The solar roof is integrated into a full function sunroof, but the sunroof can be opened without using the solar venting portion. There is a separate portion of the system that will allow the driver to turn on the electric AC for three minutes, if there is enough stored charge in the nickel metal hydride (NiMH) hybrid battery. The AC is not linked to the lead acid battery, and is run by the NiMH only, not the gas engine. The NiMH and lead acid are two separate power systems. The solar panels do not power anything else in the Prius and do not boost the power to any of the systems. The solar venting does permit less energy from the NiMH to be utilized for AC at the next startup. For trivia, the EPA will not allow Toyota to install the solar venting system on Prius with the top package V (#5). The EPA feels the Prius is too top heavy with all the additional sensors required for the radar guided cruise control and all the other high tech components in the top end option package, just FYI.
- Q: I purchased some small 3.6 v 70mA solar panels online. I have no experience with solar panels. I am confident of the layout of the parallel circuit I want to create, however I don't know how to properly connect the tabs that come from the sides of the panels. Any help on connecting them?
- Okay okorder /... That metal strip up top is negative, if you turn it around and look on the back you will see another metal strip there which would be positive. When it comes to wire, I use 24awg audio wire I got from radio shack, they only have solid wire at this gauge at my local radio shack but stranded is preferable. Solar cells are super fragile too so you're going to want to be extra careful. I then take a length of stripped wire and lay it over the silver tab, I hold it in place with some electrical tape at each end. Here is where experience comes into play, you can't use just any solder when making these connections. Well, you can but it takes a hell of a lot more time and effort to get it right. Make sure to use 96/4 silver-bearing solder. I'm not sure why but 60/40 solder does not adhere very well to the cell and usually the soldering iron has to stay on the cell for far too long which ends up discoloring it. If you need help on how to solder send me a message, you need to know how to properly tin the iron, since this is such a meticulous and unforgiving soldering job.
- Q: How do solar panels affect the property's corporate social responsibility?
- Solar panels have a positive impact on a property's corporate social responsibility (CSR) by reducing its carbon footprint and reliance on fossil fuels. By generating clean and renewable energy, solar panels contribute to sustainability efforts, promote environmental stewardship, and demonstrate a commitment to reducing greenhouse gas emissions. Additionally, solar panels can enhance the reputation of a property, attract environmentally conscious stakeholders, and align with CSR goals of promoting renewable energy and protecting the planet.
