- Q: My hubby and I are waiting to move in to our camper but have to figure out how many solar panels, batteries, etc. to get. I can't find the info per appliance for Watts and amps, but does anyone have a good, general idea of how many Watts it'd take to run the whole shabang? It's a 999, 25-foot Sportsmen tag-a-long, if that helps..It's got the following, and we'd like to run the propane things off of electric:*Refrigerator/freezer*Microwave*Oven/stove*AC/Heat*Will have a tv, phone chargers, laptop charger, but those will be unplugged when not in useThanks so much! It's such a headache.. You get SO MUCH different info from different places.. OI..
- whenever i do my gf, i use up to 900 watts of power
- Q: Can someone explain to me how solar panels can be used as modern architectural attributes? please help
- They aren't considered attributes - electrical solar panels are expanses of gray and aluminum covered with glass and water heating panels are expanses of black covered with glass. To cover the cost of investment they must be mounted at the best angle for the location and climate throughout the year and therefore may dictate the form of the roof (if sloped as on residences) or may not be visible in an architectural sense (if positioned on a flat roof of a commercial building.) No matter where placed, provision has to be made for safely accessing them for repair and maintenance.
- Q: Can solar panels be used in commercial buildings or industrial settings?
- Yes, solar panels can be used in commercial buildings or industrial settings. In fact, they are increasingly being incorporated into such environments to offset energy costs, reduce carbon footprint, and promote sustainability. Solar panels can be installed on rooftops, parking lots, or even as part of building facades to generate clean electricity that can power various operations in commercial or industrial facilities.
- Q: Green issues aside, are solar panels worth it, monetarily speaking?I don't mean that my house might be worth more or any of that. All I am asking is this: if I invest in a set of solar panels, will the cost be paid back to me over time? If so, how long will it takegt;Take into account the following:. Currently I pay the electric company around $00 per month2. I use around 400 kilowats of energy per monthI realize that exact numbers are hard to come by, but any opinions are welcome.
- I'm confident that you must pick up everything concerning solar power at www.okorder .
- Q: Are solar panels suitable for residential use?
- Yes, solar panels are highly suitable for residential use. They are cost-effective, environmentally friendly, and can significantly reduce electricity bills. With advancements in technology and decreasing panel prices, solar panels have become an attractive option for homeowners to generate clean, renewable energy and contribute to a sustainable future.
- Q: Can solar panels be installed on a government building or facility?
- Yes, solar panels can be installed on a government building or facility. In fact, many governments around the world are actively promoting the use of renewable energy sources, including solar power, to reduce their carbon footprint and promote sustainability. Installing solar panels on government buildings not only helps in generating clean and renewable energy but also sets an example for the community and encourages others to adopt green energy practices.
- 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: Was looking at 0w solar panel kit. Does this mean, all I can use is something like a 0W CFL light bulb and nothing else?
- No. The way to set it up is to store the power generated by the solar panel in a battery, then use the battery to power your lights, radio, etc, when you need the power. A standard deep-cycle marine battery is typical for panels of this size (WalMart for approx $90). A 0W panel will generate between 30 50 Watt-Hours of power over the course of a day (May-Aug weather-dependent), so this would equate to running a laptop for -2 hours, or a 0W CFL light for 3-5 hours, or a 20W stereo for .5-3 hours, etc. I find it is much easier to speak in terms of watts. Divide the watt-hours by the watts of the appliance to get the number of hours it can run. Hope that helps!
- Q: i am doing this group project fro school. I would like to know if anybody knows anything about how to read a Spec. Sheet on Solar panels and where I could go to start researching them. Anything would be great!
- Rate ,power , voltage and effencicney are four important iterms to choose one battery.
- Q: The inverter I am using gets the required 2 DC volts from the solar panel, but fo some reason it just won't output the 0 AC voltage. When the inverter is hooked to a car battery, it works just fine off the same 2 DC rating. Help me out please...
- Solar panels output a very small amount of current. Even though you're getting 2V from the panels, you aren't getting enough amperage to power even the inverter itself, let alone anything plugged into the inverter. Car batteries are able to be used with inverters because they can crank out enough amps to power the inverter and whatever is plugged into it. Inverters only step up voltages and change DC to AC. They do not increase power (wattage) potential. If you want to plug in a 20W appliance into the inverter, the 2V source must be able to deliver 20W of power regardless of voltage. In pretty much everything solar powered, the panels are used in conjunction with batteries. The solar panels slowly recharge the batteries. The batteries are where most of the power comes from. Nothing is driven directly from the solar panels themselves unless the power requirement is low enough, such as a calculator. Solar panels will have an output rating in watts (W). If the wattage of your inverter plus whatever you plug into it is lower than the panel's output rating, then it can power it directly, provided you have 00% light input into the panel.
