Parameters
- Q: Are solar panels a good investment?
- Yes, solar panels are a good investment. They provide long-term financial benefits through reduced energy bills, potential tax incentives, and increased property value. Additionally, they contribute to a cleaner environment by reducing reliance on non-renewable energy sources.
- Q: I have a 2 volt deep cylce Everstart battery with 845 cranking amps, and a Grape Solar GS-S-250-Fab5 250-Watt Monocrystalline Solar Panel . I use them to power a 48Flat screen TV, a Roku, my 65 watt consuming MacBook Pro, and a 65 watt Fan.I know from previous experience that just the battery, an inverter, and the fan, that the fan will blow for 0 hours straight.Should I really be concerned with a Charge Controller?
- Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.
- Q: Can solar panels be used in areas with high levels of humidity?
- Yes, solar panels can still be used in areas with high levels of humidity. While high humidity can affect the efficiency of solar panels to some extent, they are designed to withstand various weather conditions, including humidity. However, it is important to note that regular maintenance and cleaning may be required to ensure optimal performance in such environments.
- 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: Can solar panels be installed on desalination plants?
- Yes, solar panels can be installed on desalination plants to generate renewable energy and help power the plant's operations. This integration of solar power can reduce the reliance on fossil fuels and make the desalination process more sustainable.
- Q: Can solar panels be used on agricultural land?
- Yes, solar panels can be used on agricultural land. In fact, solar installations on farms and agricultural areas have become increasingly popular due to the dual benefits they offer. They not only generate clean energy but also provide farmers with an additional revenue stream. By utilizing solar panels on their land, farmers can offset their energy costs, reduce their carbon footprint, and contribute to a more sustainable future.
- Q: i want to build a stationary model of a solar panel and i dont know if it is going to be too simple or not i also want ideas to make it betterplease criticism is allowedmy idea was to make a case, just like a real solar panel, and take plexiglass to make it. i want to add some models of photovoltaic cells that look like they are in a solar panel . i want to add the fake shoulderings as well . i want to make the case openable by hinges.i would like some of your thoughts and ideas to help me .thx
- For a mock up model you might try a fabric store or shelf paper with a pattern that mimics solar cells. Or just find a good pic on the net and print out several copies to glue on.
- Q: does it mean that it can get that much in a day? Or like, in an hour?

- Q: Can solar panels be used in areas with high levels of snowfall?
- Yes, solar panels can still be used in areas with high levels of snowfall. While snow accumulation on the panels can temporarily reduce their efficiency, modern solar panel designs and technologies have improved to withstand heavy snow loads. Additionally, the angle at which solar panels are installed and their smooth surface can help snow easily slide off, allowing them to continue generating electricity even in snowy conditions.
- Q: Im fourteen and looking for a career I already know solar panels capture the sun and turn it into energy but i would like to know more.
- light from the sun hits the atoms and excites the electrons. This knocks the electrons out of the atom and then the electrons travel in a certain direction. This is the basics of electricity... flowing electrons. And so there's your direct current. I'm sure you could find out more by googling how do solar panels work
