Q:I thought that I had a fairly good understanding of watt's law, but i'm starting to doubt myself.If I have a load of 4500watts at 240 volts, how many watts of solar panels do I need, if the solar panels are at 2v?Yes, Yes... I have a charge controller, batteries, etc...So the way I looked at this at first:watts = volts * amps For the load4500 = 240 * xx would be 8.75aFor the power source (each solar panel)00 = 2 * xx would be 8.3a8.75 / 8.3 = 2.25, rounded up = 3So... based on that I came to the conclusion that I needed 3 solar panels...But... then I was thinking. Does it work that way?Or do I need 4500 / 00 = 45, aka 45 solar panels?In other words...If I have a 2v power source, how many watts do I need to drive a load of 4500w at 240v?ThanksMatt
The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.
Q:Can solar panels be installed on commercial buildings?
Yes, solar panels can be installed on commercial buildings. In fact, many businesses and organizations are increasingly opting for solar panel installations to reduce their energy costs and environmental impact. By harnessing sunlight and converting it into electricity, solar panels provide a sustainable and renewable source of power for commercial operations.
Q:How much candle lights is required to operate a 205 watt solar panel?
That's hard to tell. A solar panel produces somewhere between 7 and 0W per square foot under sunlight exposure. You should calculate the light intensity of sunlight, and then calculate the light intensity of a candle (You'll have to look that up in some physics book or the internet) and then just multiply the number of candles until you match the intensity of sunlight. Realistically, you would need so many candles that you wouldn't be able to fit them in front of the solar panels, assuming you don't end up with a huge fireball.
Q:Can solar panels be used to power an entire home?
Yes, solar panels can be used to power an entire home. By installing a sufficient number of solar panels on the roof or in the backyard, homeowners can generate enough electricity to meet their household's energy needs. Additionally, excess energy produced during the day can be stored in batteries or fed back into the grid for use during nighttime or cloudy days. The size and efficiency of the solar panel system, as well as the energy consumption of the home, will determine its ability to fully power the entire house.
Q:I recently bought a house with very old solar panels (about 25 years old) that don't appear to work properly. They are supposed to heat the hot water heater but they don't always work, and recently have staretd leaking. So, I have had them turned off and now we're just using electricity to heat the hot water. My question is, is there any tax credit money (stimulus or otherwise) available for people to (a) repair old solar panels or (b) replace them with new ones? How does the credit work?
Congratulations okorder /
Q:About how much would it cost to purchase and install solar panels for the average American house so that the house can be off the power grid and use the same amount of electricity as it normally does?
My friend has a system with 6 Panels, I think about 6 large batteries (Like Golf Cart Battery), a 5 KW Generator. It also has all the electronic controllers and monitors. He has about $30,000-$35,000 in his system. It does pretty good except it will not support air conditioning or heat without running the generator which is expensive. He has some niehbors that have air conditiong, but they use a gas / ammonia cycle for that. Caution, even with these systems they must be very careful with power usage, or they must run generators. They are located in the Sonoran desert where the sun shines just about every day so it is the very best of conditions. Based on this, I would say a system that would match the average household usage would cost around $80,000 or more, and would need a huge roof or large open area facing south. Probably not practicle, but possible.
Q:I want to know how you can store energy using a solar panel. The energy stored needs to be stored so that a light or laptop charger can plug in to it.
Batteries my man... but you will need a charge controller the silicon panel will produce dc and you will need an inverter for an ac light
Q:I'm looking at solar panels and I have NO IDEA what this stuff means.They come in catagories of Watts. What does that refer to? If a solar pannel is in the 200-watt catagory, what does that really mean? Will it produce 200 watts an hour, a day, a week, a month, a year?? How many watts of energy does the average house use up in one month? I really wish they would just tell me on the website!! :(0 points!!!!!!!! :D
Watts is a measurement of power which is a combination of Voltage x Amps Example: a 200 Watt panel can produce 6.6 amps at 2 Volts. (200 = 2 x 6.6) If you bought a 24 volt system the same 200 Watts would give you half the amount of amps since the power (watts) is the same. When determining your needs for a solar system there are many factors that have to be taken into account. The amount of power you use will depend on what appliances you have in the house, how much you use them, and how careful you are with vampire loads (A TV or stereo will use some power even when turned off unless you unplug them). The amount of panels you need will also depend on your battery system, amount of sunlight that you have in a day and how many days of reserve power you think you will need based on the weather in your area. If you wanted to completely run your house on solar energy you are looking at an investment of $5,000 - $20,000 or even more. There sometimes are tax incentive depending on where you live that will reduce your overall cost. Some examples of power usage: Toaster : 800-500W Microwave : 600-500W Dishwasher : 200-500W Washing Machine : 500W Vacuum Cleaner : 200-700W Iron : 000W Clothes dryer : 4000W Ceiling Fan : 0-50W Table Fan : 0-25W Electric Blanket : 200W Hair Blow dryer : 000W Electric Shaver : 5W Laptop Computer : 20-50W Desktop Computer : 80-50W TV (9 colour) : 70W Clock radio : W Fridge / Freezer : 500W 25 colour TV : 50W Electric Kettle : 2000W
Q:Someone Said It costed them 50,000 To Install Solar Panel In their House and 35,000 For Installation. Is that true?
Are they saying that the panels cost $5k and the installation cost $35k? Or are they saying the panels were $50k, plus another $35k for installation, making the total $85k? Possibly the data was from several years ago. $5k buys 6 kW of panels today, larger than goes on most houses. Installation depends on local labor costs, but should not be more than about $5k in the US, unless the system is huge, or unusual, such as a standalone system on a concrete pad, instead of just on the roof. The system on our roof is roughly 3 kilowatts. If installed today, the parts would cost about $9k. After federal tax credit, $7k. Labor depends on the local situation. We installed our own, so didn't pay any labor cost.
Q:If i wanted to get a 5 KW solar Panel does it mean it produces 5KW a day/hour/year!?!?i need 2555.35KW a week and i don't know how many or what kind of solar panels i need.Please somebody help me
It means that it will produce (at best) 5kW when the sun is shining in an ideal position, in hour that's 5kWh so, on a good summer day it may produce a total of 25kWh nothing at night see the link for a 5kW system, you need at least 0 possibly 20 times that.
