- Q: Why might energy from the solar panels sometimes be near zero even in the summer?
- Because when the sun is down there is no solar energy, therefore they produce zero energy. This can happen any time of the year when the sun has set. But not to worry, they the sun will rise the next day. ;-) If you need constant power, it is best to connect the solar panels to the grid or to batteries to have power throughout the day and night too !
- Q: Online stores selling solar photo-voltaic generation kits gives specs indicating the power generation capability of the system. For example, Solar World Grid-Tie Solar Electric System with 245W Panels PV Powered PVP2000 Inverter, .2 to 2.4 kW. This seems to indicate that the system can generate .2 to 2.4 kW. Is that per day? Per month? I'm trying to calculate the return on investment, but can't because I don't know how much power a system such as this will generate in a month.
- The $25,520 price amounts to about $8.5 a watt which is high, I would've expected between $2.50 to $5 a watt and those are dated prices so it sound like the vendor is raking the price up. You didn't mention how many months your $75 financing is for but keep in mind that at 3 kw for 8 hours a day for 30 days at 2 cents per kwh, you would generate $86.40 so you will be paying about twice as much for your solar power as you would had you bought the power from the grid. Mind you, for people on a fixed income, there is the security that the cost will not rise ( if properly insured ) so there could be an advantage to paying a premium for your power if you're on a fixed income. I'd say it's a rip off but I also believe solar has a ways to go even with subsidies before it's an economic choice and that's usually not a popular stance with the green washed crowds.
- Q: Can solar panels be used to power air conditioning or heating systems?
- Yes, solar panels can be used to power both air conditioning and heating systems. Solar panels generate electricity by converting sunlight into energy, which can then be used to power various appliances and systems, including air conditioners and heating units. This allows for more sustainable and environmentally friendly ways of cooling and heating buildings.
- Q: Are solar panels affected by temperature?
- Yes, solar panels are affected by temperature. High temperatures can decrease the efficiency of solar panels, causing them to produce less electricity. However, cold temperatures can actually improve their performance to some extent.
- Q: Could anybody give some review about Homemade Solar Panel.
- Have okorder . It may extremely teach everyone!
- Q: Are you a Solar Panel Specialist/Genius/Enthusiast?
- Yes and No. I'm hardly a 'genius' or 'specialist' but I have built a couple solar panels on my own. They're actually pretty easy to construct and you can find all of the materials at your local hardware store. Each panel cost me about $60 to make. Solar technology is jumping by leaps and bounds, becoming more and more efficient :photo voltaic cells, for example. Solar energy is a viable energy source, that's for certain.
- Q: Can solar panels be damaged by hail or other elements?
- Yes, solar panels can be damaged by hail or other elements. Hailstones can cause cracks or dents in the panels, impairing their functionality. Other elements like heavy rain, strong winds, or debris from storms can also potentially damage solar panels. However, most solar panels are designed to withstand typical weather conditions and are often tested for durability.
- Q: Have a 20V 40W solar panel and it is attach to two backup batteries. Just want to know know how many watt of inverter do I need?
- It depends on what you want to run from the panel. A 20W inverter might last a long time, but would not run much. A 00W inverter might run down your batteries in a few hours. It might help if you posted how much capacity (Volts, Amp-Hours) the batteries have.
- 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.
- For water heater type of solar panel the hot panel has more radiation losses reducing the heat available to be transferred to the water. In PV panels it has got to be characteristics of the PV cells. If the conversion efficiency drops with temperature rise then only this can happen. PV=photo-voltaic
- Q: okay so my teacher is trying to install a solar panel but we have a problem we don't know where to ground it because it will be a movil house. guys do you have any ideas?
