- Q: i want to go off grid with solar panels but i need to know how many vots and watts i need to power my house
- you must consider what electrical appliances you want to use, eg. do you have an electric stove? clothes dryer? air conditioner? heater? watts are watts, solar panels are used to create d.c. electricity which is stored in batteries then inverted to a.c. household electricity the d.c. batteries are usually 36 to 48 volts then this is converted to 20 volt a.c. when you figure out the watts being consumed in your household you size your batteries and inverter to these requirements. on your current electric bill you should see a charge for kwh, kilowatt hours= watts in thousands x hours. If you use 25 kwh per month your house is using 35 watts per hour x 720 hours in a month. you would then want sol.ar panels that charge at least 70 watts per hour because roughly half of the day it's dark depending on where you live December is even less of course in the northern hemisphere. Your batteries need to have capacity to hold a days worth of power, batteries are rated in amp hours, amp hours x volts = watt hours. I hope this points you in the right direction. All of this being said be sure to buy your system from a reputable dealer, someone with experience and good references. I am an electrician and have seen systems put in that are completely worthless because they were not sized properly and It sucks to see that someone paid $30k or more for something that is completely useless, it sucks even more when they ask me to help them and I say pay another $30k to up size the system to what they need. Remember you don't get anything for nothing so be prepared to spend money initially and be prepared to be live very energy conscious in your day to day life. Good luck
- Q: I know absolutely nothing about electronics but have a lot of money. I am thinking of buying the Sunforce 3730 30W monocrystalline solar panel (the best I could find that was that size or smaller). What would be a good battery to go with it? I am thinking of buying a 2V Concorde Sun Xtender (again, the best I could find). But how many batteries will I need? I want enough batteries that it would take the solar panel 2 days to completely charge them from empty (bearing in mind the unavoidable inefficiencies like cloudiness/changing sun angles). Also, what other stuff would I need, like I hear something about a quot;charge controllerquot;? Any suggestions would be appreciated.
- If you are at a location/time where the panel will put out less power, you can adjust the battery size accordingly. And running a battery to empty is very bad for it's service life, so it's better to go a bit bigger.
- Q: Can solar panels be used on boats or RVs?
- Yes, solar panels can be used on boats or RVs. In fact, they are a popular choice for these applications as they provide a reliable and environmentally-friendly source of power. Solar panels can help to generate electricity for various onboard systems, such as lighting, appliances, and charging batteries, making them an excellent option for those seeking off-grid power solutions while on the move.
- Q: How to make a simple solar panel?
- There are many kinds of solar panels. Please specify single crystal, poly crystaline, gallium arsenide, thin film, or water heating solar panel. How much detail do you need? Are you actually making one or just writing a report? If you expect a meaningful answer you need to provide background information.
- Q: How do solar panels affect the resale value of a property?
- Solar panels can have a positive impact on the resale value of a property. Studies have shown that homes equipped with solar panels tend to sell for a higher price and at a faster rate compared to homes without solar. This is because buyers are increasingly interested in energy-efficient and sustainable features. Additionally, solar panels can help reduce energy costs, making the property more attractive to potential buyers.
- Q: Can solar panels be used in areas with extreme temperatures?
- Yes, solar panels can be used in areas with extreme temperatures. Solar panels are designed to withstand a wide range of temperatures, including both extreme heat and cold. However, it's important to note that extreme temperatures can affect the efficiency and performance of solar panels. High temperatures can cause a slight reduction in energy output, while extremely low temperatures can decrease the efficiency temporarily. Nonetheless, solar panels are still a viable and effective renewable energy solution in areas with extreme temperatures.
- Q: Do solar panels require regular cleaning?
- Yes, solar panels do require regular cleaning to ensure optimal performance. Dust, dirt, and other debris can accumulate on the surface of the panels over time, blocking sunlight and reducing their efficiency. Regular cleaning helps to remove these obstructions and maximize the energy output of the solar panels.
- Q: I'm doing a science fair experiment with a tiny two-inch solar panel that only gives off like .5 volts of energy, but I need to know how many volts an average sized solar panel (like one you'd get to run your house) would produce. And how many panels do people usually get?
- You should read up on the different electrical units. You say .5 volts of energy, but this makes little sense. Energy is measured in Joules. Power in Watts. Solar panels will produce different voltages and currents, depending on the amount and angle of sunlight hitting them. Power = volts * amps. Before installing solar panels a home owner should do an energy audit to find out how much power they currently use - and how much that could be reduced with some easy changes. Solar panels are expensive, so it makes sense to reduce the amount that you need to install. In some places you can sell extra power back to your utility - so having extra panels might give you some small amount of money back - but this is rarely enough to justify the cost of the extra panels. I put 28 panels on my house (see picture in source URL). My utility has tiered pricing for electricity (first few kWh each month are cheap, but price for extra ones goes up in stages). My panels keep me from having to pay the higher rates.
- Q: Do solar panels require a battery for energy storage?
- No, solar panels do not require a battery for energy storage. However, if you want to store the excess energy generated by the panels for use during non-sunny periods or at night, a battery storage system can be installed.
- Q: Okay, so I have a science fair coming up soon and I need help with my project. SO - What should I use to demonstrate with the propeller? A toy boat? Plane? And I only have mini solar panels ; so how do I put the solar panels on the toy boat/plane to make the propeller move off of the sun's energy? Thanks. Steps please!
- Solar panels produce electricity. To move the propeller you need mechanical motion. An Electric motor converts from electrical to mechanical power. Most Solar Panels produce DC electricity as do batteries so you need a DC motor that is sized to match the Output of your solar panels. For small temporary projects like this I find that hot melt glue is great to assemble parts. Using a voltage meter you can expose your solar panels to a strong light (or one equal to what you expect during your demonstration) and measure the voltage across the terminals. This may help to size the motor. It depends upon the size of your propeller and how it is made. Your three choices are to use it to power an airplane, to power a boat underwater or to power a boat like an air boat. You might also use the air boat concept to make a car. (air car) The air boat might be the simplest to make but you will need a body of water to demonstrate the concept. The air car doesn't have such a requirement.
