- Q: Why might energy from the solar panels sometimes be near zero even in the summer?
- Hey Cosmic, forget about Wayfare and Jenny here, but I have to say your question is a bit vague. When you say the panels produce near zero, how near? Are you using a watt meter, ammeter, or some other sort of metering device. Solar electric, or photovoltiac panels are made almost entirely of silicone wafers. Same as computer chips, when they get hot, the resist the flow of electrons. This is why most panel manufacturers advise installers to upgauge wiring if the temperature falls below 40 degrees F (5C) regularly. Below 0 C, you have to upgauge 2 wire sizes. A good quality panel will put out 50% of its rated power in very cold climates, so it stands to reason that they will put out substantially less in hot weather. Many people think places like the SW United States is great for solar because it's always sunny. In Las Vegas for example, they have 27 sunny days a month, and in August, the temperature frequently reaches 50 degrees C (20F) so people with photovoltiac panels are not even getting half their rated power on a good day. I'm not sure this is what you are asking about. Our home has been powered by the wind and sun for 2 years now. In the summer in the upper midwest, the days are warmer of course, but also much longer than in the winter. So our batteries will frequently fill up by 2:00pm, and the charge controller will taper off the solar charging the rest of the day to minimize overcharging. If you were to check the meters at 3pm, you might notice only 3 or 4 amps coming in when the array is rated at 42. This is normal for us in July and August. These are some reason why a solar array produces near zero in the summertime. Take care Cosmic, Rudydoo
- 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 solar panels be installed in urban areas with limited space?
- Yes, solar panels can be installed in urban areas with limited space. There are various innovative solutions available, such as rooftop solar panels, vertical solar panels, and solar panels integrated into building facades. These options allow urban areas with limited space to harness solar energy efficiently and contribute to a more sustainable future.
- Q: Can solar panels be used in areas with high levels of pollution from industrial emissions?
- Yes, solar panels can still be used in areas with high levels of pollution from industrial emissions. While pollution can potentially reduce the efficiency of solar panels by blocking sunlight, advancements in technology and design have made solar panels more resilient. Additionally, regular maintenance and cleaning can help mitigate the impact of pollution on solar panels, ensuring they continue to generate electricity effectively.
- Q: Photosynthesis is fairly inefficient, but efficient enough to power all life on earth.
- Silicon is a very good conducter. Probably the best for electricity.
- Q: Can solar panels be used in areas with high levels of air pollution?
- Yes, solar panels can still be used in areas with high levels of air pollution. While air pollution can reduce the efficiency of solar panels, they can still generate electricity even in polluted environments. However, regular cleaning and maintenance may be required to ensure optimal performance in such areas.
- Q: Solar panels are all divided into these squares, forming a grid like pattern. Is it possible to have a single piece of solar panel?
- Solar cells are semiconductor devices like computer chips. Current manufacturing methods create small squares of semiconductors. Companies are researching ways to make thin film solar cells that can be painted on or manufactured in large, possibly flexible sheets, but so far the technology to do that is still more expensive than making little squares and then assembling them into big panels. That may change in the near future, but I can't be sure.
- Q: Can solar panels be installed on multi-story buildings?
- Yes, solar panels can be installed on multi-story buildings. In fact, multi-story buildings can provide ample space for solar panel installations, allowing for increased energy generation and potential cost savings. However, it is necessary to consider factors such as available roof space, structural integrity, and shading issues to ensure optimal positioning and efficiency of the solar panels.
- Q: There are so many solar panels and kits it is very confusing. I need to know what exactly I would need if I had an underground home with no electricity. I want to be totally off the grid with solar power. Someone please explain to me in simple terms what exactly I need. Maybe give me a link to the right kit for me. Also are they easy to install? Are there instructions that I need to download?Thank you

- Q: How are solar panels made?
- Solar panels are made using a complex manufacturing process that involves several key steps. First, high-quality silicon ingots are sliced into ultra-thin wafers. These wafers are then treated with various chemicals to enhance their electrical properties. Next, metal contacts are added to the front and back of the wafers, allowing for the flow of electricity. The wafers are then assembled into a module, encapsulated in a protective layer, and sealed with a glass cover. Finally, the completed solar panels undergo rigorous testing to ensure their efficiency and durability before being ready for installation.
