Q:im making an energy efficiant house for science class and i need to price the house. im putting solar pannels on the roof and would u please tell me how much they are per like 2 sq. feet of a pannel?: Completely self-efficient and autonomous??? Forget it. Too expensive. It's only worth if you use like 8 lights (2-20w) about 4 hours a day, a fridge, a tv about 4 hours/day and basically nothing else or a few low consume stuff. Forget about microwaves, dryers, or other stuff. Too much watts. And that would cost you no less than 5000-6000$. You need panels (about 4 or 6 20w would suit maybe), 2 batteries (about 600Ah at least), inverter(500w/24v) and a regulator, lets say a 30A one. Just stick to normal energy supply. A single 20w panel may cost about 750$ at least.

Q:I have in mind a small solar panel that could be plugged into a wall socket. Do I need a converter or some kind of interference between the two power sources so there aren't any unpleasant explosions? I don't know much about this sort of thing so please be nice.: The other responders have given partial information. The electricity in your house is 20 volts AC and the solar panel will produce DC voltage. If you plugged in the solar panel into the wall, the solar panel would be destroyed, possibly with disastrous results. If you connected the solar panel to a DC to AC inverter, there are also dangers. The solar panel unless very large will not produce enough power to make a lot of AC, for every amp of 20 volt AC, you require more than 0 Amps of DC voltage. So most small solar panels are used to trickle charge a 2 volt battery used in backup situation. The problem is that the house AC and the inverter AC have to be exactly in phase or again you have disastrous results. If they are exactly 80 degrees out of phase, the wires now are carrying 240 volts and you will burn out the inverter, and possibly cause a fire. There are systems that will synchronize an inverter to commercial power so that you can feed the power back to the grid, but these are more complicated. If you want to use the battery and solar panel to run some lights during power failures, then you can connect the light to the common terminals of a switch, but the switch must be a break before make switch, which means that when you throw the switch the common is disconnected from the one source before it is connected to another source. Most AC switches will do this, but make sure.

Q:How do solar panels perform in extreme temperatures?: Solar panels perform best in moderate temperatures, typically between 25 to 35 degrees Celsius. However, extreme temperatures can affect their performance. In extremely hot temperatures, solar panels may experience a decrease in efficiency due to an increase in heat-induced resistance. On the other hand, in extremely cold temperatures, solar panels may experience a slight increase in efficiency, as lower temperatures can reduce resistance and improve conductivity. Nonetheless, most solar panels are designed to withstand a wide range of temperatures and can still generate electricity in extreme weather conditions.

Q:How do solar panels affect insurance premiums?: Solar panels can have a positive impact on insurance premiums. Installing solar panels may increase the value of a property, which could lead to higher insurance coverage limits. However, the overall effect on premiums can vary depending on factors such as the location, type of solar panels, and the insurer's policies. Some insurers offer discounts or incentives for homeowners with solar panels, while others may charge higher premiums due to the increased replacement costs. It is advisable to consult with insurance providers to understand how solar panels specifically affect premiums in individual cases.

Q:I paid for an appraisal and the home was valued at $25,000. The problem I have with this is my house is equipped with solar panels. I paid about $25000 for them. A comparable house sold for $225,000 4 months ago. Same amount of rooms, bathrooms, square feet, lot size and curb appeal (landscaping). But no solar panels. Home prices in my neighborhood have also gone up. I would like to know if there is any way I can dispute this as I feel I just wasted a lot of money on a incorrect appraisal.: Normally solar panels are listed as part of the house that supply heat, like a water heater or furnish. Your house would be appraised the same without the solar panel. Since the house you are references sold 4 months ago this might not be a comp your appraiser would have used. Normally a house would have to be sold within the past 90 days to be used by an appraiser. You are able to challenge the appraisal of the house you paid for. The appraiser would take a second look at the cops he/she used in coming up with the valuation of the property and see if here was something that was over looked. If you want to challenge the appraisal based on the fact that you have solar panels, it is doubtful there would be any changes. By adding the solar panels to your house might have been over built your house for the neighborhood. Look around your neighborhood to see how many other houses have solar panels. Normally in an area where houses are valued at around $200K or so would not normally be equipped with solar panels. This would not add value to your house as other houses in your neighborhood would still appraise for the same, since they would not have solar panels as the house you indicated in your statement did not have. I hope this has been of some benefit to you, good luck. FIGHT ON

Q:The first panel is located in New England, the second is placed in the Sahara desert, the third is on the Earth side of the moon, and the last is on the far side of the moon. Which panel would absorb the most sunlight over a year's time and why ? All the panels are place in optimal places where they would get the most light available.: Best to worst: far side of the moon, near side of the moon (same as far side, except for lunar eclipses), Sahara desert (not at 0 latitude, and occasional bad weather), New England (less favorable latitude, and LOTS of bad weather).

Q:i have 2 questions.. I have a 6v solar panel, if i wanted to charge batteries with that it what batteries could i charge? Could charge normal AA batteries with it our do i need special batteries.2. I have a 6v solar panel that produces watt. I want to light a bulb with it but whenever i hook it up the solar panel won't light it up. I think the current of the solar panel is too low. How can i increase the current of the solar panel: [] Use it to charge 4 pieces AA cell ( connect in series to make 5V battery pack ) for 0 to 4 hours. Good for cell rated 600mAH ,2000mAH,2500mAH. [2] Cannot increase current. Buy some more this panel and hook them together in parallel to increase current. You need at least ten pieces to make current reaches .6A to light up some 6V bulbs.

Q:I'm looking to mount a solar panel to the top of my 2003 Pontiac Montana and was wondering how i could do it without any screws? Magnets maybe?: yeah ... use dem magnets to mount it. you might enjoy a site called vandwellers google you tube vandwellers to find them. one problem with mounting it to your roof. when you want to park in the shade out of the suns heat,,, your panels are in the shade.

Q:Can solar panels be installed on a garage or carport?: Yes, solar panels can be installed on a garage or carport. In fact, these structures often provide ideal locations for solar panel installation due to their large, flat rooftops or open spaces. Installing solar panels on a garage or carport can help maximize energy generation, reduce electricity bills, and provide shade for vehicles or additional usable space.

Q:Can solar panels store excess energy?: No, solar panels themselves cannot store excess energy. However, energy generated by solar panels can be stored in batteries or other storage systems for later use.
