- Q:Can solar panels be used for powering a farm or agricultural operation?
- Yes, solar panels can definitely be used to power a farm or agricultural operation. Solar energy can be harnessed and converted into electricity to meet various energy needs in the agricultural sector, such as powering irrigation systems, pumps, lighting, and other machinery. By utilizing solar panels, farmers can reduce their reliance on fossil fuels, lower energy costs, and contribute to a more sustainable and environmentally friendly operation.
- Q:How do solar panels affect the property's energy consumption?
- Solar panels can significantly reduce a property's energy consumption by harnessing sunlight to generate electricity. By converting sunlight into clean, renewable energy, solar panels can offset much of the electricity that would otherwise be drawn from the grid. This leads to lower energy bills and a decreased reliance on fossil fuels, ultimately resulting in a more sustainable and eco-friendly energy consumption for the property.
- Q:I am wondering how to store energy from a solar panel
- I have no idea what you are doing or what you think you are accomplishing. A 235 watt panel isn't much energy. You can certainly store it with a plain old lead acid battery.
- Q:I have two solar panels that were going to be trashed at work. I want to use them to charge batteries on my RV but i noticed they put out around 20 volts in direct sunlight. So i am wondering: -isn't this way too much voltage for a 2 volt system? -do a need some sort of a regulator connected to keep them from overcharging?
- 20 volts is a common open-circuit voltage for nominal 2v panels. The panels put out about 5v at full load. If the panel puts out little enough that it takes 20 hours or more to put a full charge in the battery you can get by without a charge controller - just keep the cells topped up with distilled water. A charge controller will do a more efficient job, though. The most efficient charge controllers use what's called Maximum Power Point Technology (MPPT) which lets the panels operate at their most efficient point throughout the battery's charging cycle. Available on OKorder. The charge controller should have the same or higher wattage as the panels it controls - if you're not sure of wattage, assume that they are the same as similar area panels you find for sale. Before buying a charge controller, connect the panels through an ammeter to a discharged battery. They may have been trashed because of damage and low output. You need at least an amp for trickle charge, 5 amps for reasonable recharge times.
- Q:Can solar panels be installed on a sloped roof?
- Yes, solar panels can be installed on a sloped roof. In fact, many residential and commercial buildings with sloped roofs have successfully installed solar panels to generate renewable energy. The angle of the slope can affect the efficiency of the panels, but with proper installation and positioning, solar panels can still effectively harness sunlight and produce electricity.
- 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:It measured volts before I attached it, and after attaching the voltage regulator device, the voltage dropped down to 3 volts, even when just measuring the difference in the solar panels nodes themselves, suggesting that the entire panels voltage dropped and not just the voltage in the regulator. I tried testing it with a power supply of 7 V 0. A and it works fine, but I don't know why it won't work for the solar panel.
- you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
- Q:Dose a solar panel need the entire range or spectrum of sunlight to produce power?
- I think it's in the Ultra-Violet range because Solar Panels will still put out almost full power on an overcast day.
- Q:Can solar panels store excess energy?
- No, solar panels cannot store excess energy. However, additional equipment such as batteries or energy storage systems can be installed alongside solar panels to store any surplus energy generated for later use.
- Q:Can solar panels be installed on ground-mounted structures?
- Yes, solar panels can be installed on ground-mounted structures. In fact, ground-mounted solar panel systems are a popular choice for residential, commercial, and utility-scale projects. They offer flexibility in terms of location, orientation, and scalability, making them an ideal option for areas with limited roof space or shading issues. Ground-mounted structures can be customized to optimize solar panel angles for maximum energy production and are easier to install and maintain compared to rooftop systems.
