Q:How big of a solar panel system would I need to get ?
Since you are consuming 500 KiloWatts*hours (.5 MegaWatts*hours) per month on average, you need to find out how many KiloWatts per day, so 500 KWh*h / 30 days = 50 KWh per day. With an average of 2 hours of sunlight per day, or even more conservative of 0 hours of sunlight per day 50 KWh / 2 hours = 4.667 KW solar panel system 50 KWh / 0 hours = 5 KW solar panel system An average solar panel is 200W to 250W, so 5 KW / 200W = 25 solar panels 5 KW / 250W = 20 solar panels Solar panels are currently about $ per Watt, so 5 KW of panels is $5,000 A 5KW inverter that is about $5,000 Other incidentals are about $2,000 Total cost (not including labor) is $2,000 Price per KWh is about $0.0 per KWh for East South Central states. Savings per month is *at least* $50 since there are other charges in your electric bill other than usage that are tied directly to your usage as costs. So $50 / month * 2 months = $,800 per year $2,000 investment / $,800 per year = 6.67 years or 6 years, 8 months to pay off the system. Contact many Solar contractors in your area for competitive pricing of labor and for a more detailed analysis of your home.
Q:Hi trying to learn more about Solar panels!?
Solar panels do not store power. Solar panels convert sunlight into electricity. To store power you need batteries. The usual type of batteries used are lead-acid deep discharge( similar to car batteries). The batteries are charged up during the time the sun is out. However, as a backup you could also have a generator handy to provide power for times when the sun did not shine enough to keep the batteries charged up.
Q:How can I power 5v or .08 amps in a remote loaction via solar panel.?
First things first. 5 Volts @ .08 amps would be .2 Watts. therefore you would need at least the same amount from a solar panel to replenish the batteries. But what puzzles me is the notion that plugging it in a wall outlet ? If you use 20 V @ 0.08 then the power consumption is 9.6 Watts And what is a meraki wireless repeater? I never heard of one. I'm a FCC licensed Ham and have some idea what is available. If you need 5 volts DC, you could use twelve Ni-cads in series and just keep them trickle charged with the solar panel That would make it compact. If you were to use an automotive battery (or motorcycle), then you would need a DC/DC converter.
Q:how much does it cost to operate a solar panel?
Photovoltaic panels have almost zero recurring operating cost. Once installed, they are good for the next 20-25 years, typically. The exceptions are if the panels are not tilted, then you need to pay someone a few times a year to go up there with a mop to clean them. Otherwise, rain and morning dew make the dirt slide off automatically. The cost for your system will depend on the power needs of your school. It also depends on your location. As a government entity, a school is not eligible for the current 30% federal incentive, but may be for state incentives, depending on where you live. Anyway, once you size your system, which will be large, figure on $7 / watt cost for a large system. This would be less if you live in a state with good incentives. So for example, if you needed a 00 kW system, the price would be $700,000. $00,000 of that money is to replace the inverters that break after 5 years, so you would be paying $600,000 up front.
Q:Can a solar panel work with an inverter?
There could be a couple of reasons why it isn't working. First, 2V panels actually put out a considerably higher voltage because it is presumed that they will be used to charge a 2Vdc battery. That requires applying a voltage greater than 2Vdc, and usually there is a solar controller that regulates the solar power to the battery. It also has a voltage drop. Look at the first reference reference, and you will see these values for a particular panel: Voc: 2.6V (open circuit voltage) Vmp: 7.2V (voltage at maximum power point) Voc is the voltage the panel produces under standard sunlight and temperature conditions (25°C), with no load applied. As load is applied, the voltage drops (see reference 2). Power is the product of current times voltage, so at one set of conditions (namely at Vmp) maximum power is available from the panel. Your inverter might not be working for either of two reasons: ) it has input protection circuitry that locks out operation when it senses an overvoltage, as in the 2.6V open circuit voltage, or 2) the panel does not produce enough current and the voltage from the panel collapses under excessive load. For example, if you load your inverter to 20W, then nominally the 2VDC input to the inverter must supply 20W/2V/eff = 0A/eff Assuming the inverter has an efficiency of 80%, the input current required is: 0A/.8 = 2.5A A solar panel operating at maximum power would need a rating of about: 2.5A x 7.2V = 25W Is your panel that big? The other option, as mentioned by others, is to charge a battery that runs the inverter. Other nuances: Voc increases as temperature decreases. Sunlight intensity varies (obviously), so the panel may produce less than rated power. The power specifications often are printed on the back side of the panel.
Q:can a l.e.d light power a solar panel?
While I understand Search's answer, because it was also my first reaction, am I wrong in thinking that this is some sort of science fair project, for which you need to power a solar panel indoors as though it were being illuminated by the Sun? The question at least makes sense in that context. Solar panels provide modest power even from room lighting, sometimes calculators are powered by small panels, but that is a tiny amount of current. . You'll probably do better by asking this question (a bit more clearly) over in Engineering. It's not really an Astronomy Space question, though there may be some crossover between the two groups of users. Meanwhile, while some white LEDs can be pretty dazzling to the eye, I don't know how much actual power they are pulling down compared to what you'll need the panel to generate, but I don't see why it shouldn't work. I just don't know how many LEDs you would need. . .
Q:how many solar panels do I need for my house if in average i consume 880 kwh?
That okorder.com/ They helped me a lot when I was pursuing solar. They will provide you with a free solar quote and give you all the information you need regarding eligible incentives, a feasibility analysis, your estimated annual savings, payback period, and return on investment. All in all, they will be able to provide you with everything you need to know in order to make a smart decision. Good Luck!
Q:Could you have a solar panel in space?
Hi There Solar panels work better in space than in the atmosphere and wireless transmission of power is now becoming possible but rarely practical. Currently more practical would be orbiting geo stationary large scale mirrors focusing light on panels on earth. In another 50 years who knows? Energy being transmitted wirelessly generates heat and radiation. I suspect that if a powerful enough solar array to meet earthly needs was put in orbit then transmitting that sort of power through the atmosphere would cause issues all of its own. Regards vk4ari

Q:Questions about charging batteries via solar panel...?
You did not give the AH rate from your 24V battery pack,therefore , unable to suggest a correct current rate solar panel. The solar panel open voltage rate at least 30V to charge a 24V cell. No harm to controller since the charging current is so small even bike is in running condition.
