- Q: Can solar panels be installed on a restaurant or food establishment?
- Yes, solar panels can be installed on a restaurant or food establishment. In fact, many restaurants and food establishments are increasingly embracing solar energy to reduce their carbon footprint, lower energy costs, and demonstrate their commitment to sustainability. Solar panels can be installed on rooftops, canopies, or even on unused land surrounding the establishment, providing a renewable and clean source of energy to power the operations.
- Q: I contend:As far as the solar panels causing global warming I'll try to explain. 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). The net heat gain is zero. 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 result is a net gain in earth's temperature.Right or wrong?
- 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: Ok, so I've been having much success with the joule thief circuit and a LED, but i tried hooking it up to a small solar panel that can put out 2.5v on it's own, and can light up a white LED dimly by it self to the joule thief and it will not work ....my question is why? I already trouble shooted it, the circuit is not the problem, is it the amount of amps the small solar panel is capable of? not enough?
- Solar panels convert light energy to electrical energy with an efficiency of around 5%. A SMALL solar panel will only produce a small amount of power (watts) your joule thief circuit wont help because as you draw more current from the solar panel the voltage will drop; and your joule thief circuit just reduces the efficiency of the whole system Try adding another solar cell in series to get more voltage and more power.
- Q: all i want to do is provide enough electricity for 2 fluorescent bulbs i was looking at some 80 watt panels how many of those would i need and what else do i need for storing the electricity for use at nite? and how much would it all cost?
- The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.
- Q: How do solar panels impact the electricity bill?
- Solar panels can significantly reduce or even eliminate electricity bills as they generate clean and renewable energy from the sun, reducing the reliance on traditional grid electricity. By harnessing solar power, homeowners and businesses can offset their electricity consumption and potentially earn credits by feeding excess electricity back into the grid. This can lead to substantial savings and a more sustainable energy future.
- Q: Around this time here in Georgia we will begin to get some big storms with high winds. I have a solar panel on a mount that isn't all that sturdy and could be knocked over with any winds pretty much above 5mph. I can't put anything in the ground to do this. I used to have it mounted to the roof of a playground for the most sunlight, but because of the angle of the sun and the tree leaves, I have to have it on a quot;portablemount so I can move it throughout the day, and I can tell you one thing is certain, and that's that it isn't the most sturdy thing ever. I'll have it a little better next weekend but it'll still be able to easily blow in the wind. Should I just hang the panel along the wall during a storm then reconnect it to its base once it's over?I'm pretty good with wood, so any wood creations to help out with the thing would greatly help. Just please keep it on a low budget.
- Solar panels are a costly and significant investment. Therefore, protecting them from harm should be a top priority. Unfortunately, moisture and water are common ways for solar panels to become damaged or broken. Safekeeping solar panels from both of these threats is a simple, inexpensive procedure, and doing so might save the solar panel owner a bundle if carried out correctly Instructions : Set a thick strip of silicone between each cell when putting the solar panel together, in order to prevent moisture seepage. 2: Use Plexiglas instead of glass as the face of your solar panel. Plexiglas is less liable to break and therefore safe from hailstorms or accidents. 3: Glue adhesive silicone to each side of your solar panel(s), adding additional sealant and protection from water to your commodity. :)
- Q: The colder a solar panel gets the more efficient it seems to be. As the panel warms, it loses some efficiency. Why is this so? Please explain in a way you would expect a high school kid to understand it, as I am a high-schooler and i have to explain this to other high-schoolers.
- All PV Solar Panels are affected by heat. The hotter the solar panel, the lower the power output - but how significant is the effect. I decided to test one of our small 6V 250mA Solar Panels to find out. Solar Panel next to halogen lamp with temperature probe. Reproducing the kind of temperatures solar panels experience in hot climates is not easy on a cloudy May day in the UK, so a 50 Watt halogen office lamp was used at a distance of 55mm from the solar panel as a sun substitute. This guaranteed a constant level of light would be incident upon the solar panel ensuring the quality of the results collected.
- Q: Need solar panel info with dimensions and also the total cost of the whole equipment for setting up of the required solar panels for a 2-story home
- There are many, upon many variations of equipment needed for a complete solar home. I would call several contractors in your area that deals with it and get estimates. You have to look at what your wattage diet is at your home. How many watts are you using for your AC and heat. Which can vary by age, efficiency, insulation of home, etc. Look at your electric bill for a normal summer month and a normal winter month, then estimate your heating and cooling (Sometimes can be as much as 70% of the bill). You will see on your bill your toal kilowatt hours. ( Kilowat = 000 Watts) Solar systems can start as low as $2.00/watt, but can rapidly approach $20.00/watt depending on the difficulty of application etc.... Here is the great thing, in many areas of the country there may be rebates from the county or state. And what you don't use can be fed back into the grid, and you get paid for it. But as always - Call a quailified contractor and get the right system for your home.
- Q: How efficient are the solar panels....?
- Commercial monocrystalline panels are typically 8% efficient but inverters can be 65% to 90% efficient and lead acid batteries are 50% efficient at charging and 92% efficient at discharging plus they self-discharge at 3% to 20% per month.
- Q: Do LED lamps ever go bad?What's the life expectancy of solar panels?
- LEDs last approximately 50,000 hours of operation, continuous or non-continuous, it doesn't matter. 50,000 hours. Solar panels will, theoretically, last until the end of time. The support structures will fail long before the panels themselves. Inverters, battery banks, op-amps, transformers, control boards, etc. will all fail long before a solar panel stops making juice.
