FAQ
1．How do I protect my solar system during subzero temperatures?
If you have a system that is operating in areas with subzero temperatures then freeze protection must be implemented. The easiest means of preventing freezing is to use a controller with a low temperatures setting, so when the manifold temperature drops below a certain pre-set temperature (5oC/40oF), the pump will circulate, warming the collector with water from the bottom of the storage tank. The pump will not run continually, just periodically, the frequency of which will depend on the outside temperature. In extremely cold areas, a closed loop using a glycol/water mix may be appropriate.
2．Will water be heated on a cloudy day?
Yes. Although the heat output of the solar collector is reduced on overcast days it will still be able to provide heating. If it is a heavily clouded day or raining, then more gas or electric boosting may be required to maintain water at the required temperature. This system will be automated so you don't have to worry about running out of hot water on a rainy day.
- Q: where to find used solar panels?
- Used Solar Panels R Us
- Q: So, I've seen cheap solar panel kits for sale from Harbor Freight, and regardless of whether or not I were to buy a set from them or someone else, I was wondering what the process of implementing a small-scale solar system into your household electrical system would be.I've read articles that started out too in-depth or were speaking of systems on a much larger scale.Can it be as easy as buying the panels and inverter, and plugging it into a socket, or is there more to it?Some of the articles I was reading had mentioned having to contract with your electrical supplier, having to have an electrician tie it all in in some special/ necessary way, using a battery pack (would this be necessary for a tied-in system?), or using the system to only power single items, like a water heater, or plugging items into a connected battery-pack, all of which I'm not sure is necessary or needed for what my goals/ means are/ would be.
- Grid tie inverters are expensive, but you might find a used one cheap on E-Bay, Crags list. Almost any grid tie inverter will work as you are thinking low power, but it likely needs to be 50 hertz or 60 hertz, which ever you have, and 230 volts ac or 20 volts ac which ever you have. It will work for a range of dc voltages, so your solar panels need to produce voltage near the center of that range. I considered buy the 3 PV panel set of 5 watt panels that Harbor freight sells. but I did not determine if the three panels can be conveniently connected in series to produce about 50 volts at light loads, or 00 volts if you buy two sets. You probably do not need the load controller, that comes with each set. I think most grid tie inverters automatically adjust to the dc voltage you supply them, unless it is below some minimum such as 50 volts. It is illegal to connect ordinary inverters to the power company, but they will probably not notice a small system unless you burn your house down. Most inverters will phase lock with the power companies frequency, but they are not designed to do that, so bad is likely unless you connect a resistor such as 0 ohms at 00 watts in series with the ac out of the inverter. If the resistor smokes you should disconnect promptly, then try again to see if you can get phase lock quickly. No smoke, likely means you are one of about 000 co-generators on the electric grid, You can short out the resistor with short piece of very fine wire which will hopefully melt if something goes wrong, such as the power company not sending electricity for 0. seconds or longer. Nearly all inverters have an over load feature, so the thin wire is a back up. Please be careful as people sometimes don't survive an electric shock at 20 volts.
- Q: If you were to be asked to write a material(s) report on either -solar panelsor -aircraft fuselageWhich would you choose?well i was asked to choose between these two,so i guess that if i choose what the majority wouldn't, i might just score a little bit higher,what do you think?if you are the lecturer you would want something different right?
- Aircraft fuselage. Right now solar panels are all the rage, and there's lots and lots of nonsense written about them. Aircraft design is old technology, but still quite fascinating. Learn about riveting and gluing techniques, the various aluminum alloys or plastics used, and compare the weight of an airplane fuselage with that of a building of comparable size.
- Q: Do solar panels work in cloudy weather?
- Yes, solar panels do work in cloudy weather. While they may not produce as much electricity as they would on a sunny day, they can still generate power from diffused sunlight. Cloudy conditions can reduce the efficiency of solar panels, but they are still capable of converting light into electricity, making them a viable option for renewable energy even in less sunny areas.
- Q: Can solar panels be used in disaster relief efforts?
- Yes, solar panels can be used in disaster relief efforts. They provide a reliable and sustainable source of electricity, allowing for the operation of critical equipment such as lights, phones, and medical devices. Solar panels can be quickly deployed in affected areas and can help reduce the reliance on fossil fuel-based generators, thereby reducing pollution and the need for fuel transportation.
- Q: They have been around long enough to be cheaper. Unless they are made out of a natural material that is rare and hard to find, there is no reason why they should be so expensive. On another note, I think that all low power devices like cell phones and even laptops should have solar panels. Even if it is not enough to fully power the device for a long period of time, it will provide some electricity savings and with millions of people saving a little power adds up.
- materials and process... if they could be built in a sweatshops, by kids, in Malaysia, they'd be cheap and everyone would use them
- Q: I am planning to run a couple of dc motors on solar current. I have a couple of 450mA 4V, 200mA .5V, 00mA 9V solar panels with me. I need to run a pair of .5A 9V motors. Suggest me a circuit along with other equipments I might require. For your info, I am trying to build a solar powered drone / UAV
- I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.
- Q: i need to cut down on electricity bills, and so i was wondering if someone could give me step-by-step instructions, or websites that have step-by-step instructions on how to build an electricity generating solar panel.
- I have been researching solar electric (photovoltaic) for a while now and find that the up front cost will generally take 0 or more years to pay back. While the life expectancy is 30+ years, giving you 20 years of free energy, most people don't have the initial 20-30,000 start up cost. I've found that wind turbines can be built fairly inexpensively and parts can be easily obtained. The trade off is that wind turbines require maintenance and you also need to be in a reasonably windy area, many municipalities will have restrictions that will impact your ability to put one up as well. The batteries/converters to store/convert your power from DC to AC can also get expensive. Good Luck and thanks for being Earth Friendly and cost conscious! Let's hope that the cost of these products begin to decline as usage increases and new technology develops.
- Q: Can solar panels be used to power swimming pools?
- Yes, solar panels can indeed be used to power swimming pools. Solar panels can generate electricity from sunlight, which can be used to operate pool pumps, heaters, and other equipment, reducing the reliance on traditional electricity sources and saving on energy costs.
- Q: my dad wants to run all his lights in his shop on solar panels, he has 9 600 watt hps lights. how many solar panels would it take to pull this off
- If he lives in a sunny area, he should contact a local solar installer about getting a grid-tied solar system to offset his electric bill. It's not necessary to supply all the electricity from solar. The system will work seamlessly right alongside grid electricity, and your father can choose whether to supply 20% of the electricity or 99% by sizing the system appropriately.
