Q:Using a solar panel to make energy?
Small solar panels produce almost no power that matters to anything. A whole square meter may produce 80 Watts when facing the noon sun in Arizona. take that down to 28 Watts in Erie Pa. The 80 Watts can charge a 2 volt battery at about 8 amps times 6 hours, or 48 Amp hours per day in Arizona or perhaps 5 amp hours/day in Erie. The amount of energy you can save declines as the battery is more charged so you need to use up the power stored before you have more to save. To do that charging you need a circuit that will carry 8 amps, including a voltage regulator. So, if your circuit can stand 20 amps the person in Arizona can run 2 square meters of panel. It may seem strange but the same is true for the person in Erie. The person in Erie has to allow for the maximum output of the panel, not the expected average. The person in Erie will occasionally have really clear skies and put out maximum rated amps. The amperage that the batteries can put out at maximum should not be used. That will destroy the battery. One puts a breaker on each output circuit to protect the circuit and a breaker that limits battery output to 20 amps based on a battery rated at 800 amps. That 800 amps is surge capacity. One or two panels does not really justify having this capacity for battery and circuitry. I can think of using it to provide an emergency LED lighting system.
Q:Can I use a 250 watt solar panel to power a medium sized upright fridge?
Solar panel alone? No. With the appropriate storage system and inverter, perhaps. You will need to do the calculation - as follows: In a solar day that averages about eight hours, you will generate about 67% of your rated output over those 8 hours. That means you will have made 340 watts. Your refrigerator will run for about four (4) hours per day on average if you are very careful about opening and closing. If you have a 400-watt (average-when-running) fridge, you will have a small cushion that will be absorbed by inverter losses, charger losses and so forth. So, with an adequate set of storage batteries, a good charger and a good inverter, you just might be able to operate that small fridge. No icemaker, no other power drains. But, two 250-watt panels would be better.
Q:Solar Panel Question?
There is always a lot of confusion on this question so I built a webpage to show people how to do the math and pick the right system size. Most all public utilities will trade you kWh for kWh and then either settle up with you at the end of the month or every 2 months. So one week you might have all rainy days but the next 3 weeks you have 0 hours of bright sun even in the winter. This means you have no need to put batteries on your system unless you have a lot of power outages. Then you only need a few hours of battery backup power. At most 24 hours.
Q:What about solar panels?
This is a site that can help you estimate the size and number of panels that will power what you intend to provide for. There are plenty of sites selling the panels, so compare prices. Also, check whether your state is offering the rebate like the state of CA is and what the restrictions, terms and conditions are. Even with the rebates they are very costly, so be certain to calculate the pay off period for your application to see whether it is a cost efficient option for your energy usage.
Q:Benefits of Solar Panels?
The solar panels that we all simply would think are the greatest thing ever are very, very expensive and require strip mining of huge areas of land to make. For several million dollars you can buy what usually is mounted as power source for space satellites upon your roof. This 2'x2' panel and a barrage of battery storage takes care of all the electrical needs you could ever have at home. But this profoundly environmentally destructive technology is not what you had in mind, I'm sure, but is what has been around for quite some time now. It's been a challenge to make solar panels without using complex chains of excited rare metallurgies, but we seem to be getting better and better at it--but I trust others should help you with the practical, now that you know the best panels are not best for us at home.
Q:Can one benefit from solar panels?
In theory, yes. But the fact that nobody is doing it implies there is something wrong with the idea. Solar panels are not exactly new.
Q:Solar panel power question?
The specifications you give say the solar panel produces 5 watts at 2 volts (DC) so that isn't enough voltage to power an ordinary (20-volt) light bulb. You could get 0 of these panels and connect them in series so they put out a total of 20 volts and the total power available would be 50 watts. The panels would light the bulb that way, provided the bulb isn't over 50 watts and you can afford the panels. A panel does provide enough power for a 2-volt car light bulb less than 5 watts. However, the maximum current you can get from these panels is .25 amperes (5 watts divided by 2 volts = .25 A.) This isn't enough power to run your pump which takes 6.5 amperes - at 20 volts, that would be 780 watts. Another thing to check is the pump motor; many electric motors are designed to run on AC only and will be damaged if you try to run DC through them. Remember solar panels produce DC so the raw output from a panel will not work on an AC motor.
Q:Does anyone know a company that will make custom solar panels?
Make okorder.com
Q:Selling homemade solar panels?
Would those be heating panels, or electric panels? If the latter, you would not have any safety certifications (I assume), so the panels would be illegal to use for a serious, grid-tied system. You would need to make this clear to your customers, that they could only connect to stand-alone systems. If this is in the US, there is always some finite danger of lawsuits if your product is defective. If the water heater leaks or blows up on someone's roof, you might have to go to court to defend yourselves. Even if you disclaim all warranties, in some states, if you sell something as a water heater then it has to heat water reasonably, and also not be hazardous. In other words, fit for its purpose. Check your local laws.
Q:how can i build my own, cheap, solar panels at home?
Build from scratch, sorry your way over your head. (mine too). There are lots of companies that will give quotes on doing what your looking for, but plan on spending 20 to 50K depending on where you live and what you need. I don't know about where you are, but My hydro bill is almost half delivery charges. Therefore I could cut back by 99% on the usage, and still only have my bill come down by less than 50%. I understand you desire to lower costs, but unless you do a big change(lots of outlay) your savings will be small. By all means shut off lights your not useing etc. there are other ways of lowering your household bills better way is solar heating. But this also depends on where you live. I'm building a solar collector for 2 houses , Contact me at davethree@persona.ca and I'll pass on more info
