Product Description:

Ground based mounting supports include:

    Pole mounts, which are driven directly into the ground or embedded in concrete.

    Foundation mounts, such as concrete slabs or poured footings

    Ballasted footing mounts, such as concrete or steel bases that use weight to secure the solar module system in position and do not require ground penetration. This type of mounting system is well suited for sites where excavation is not possible such as capped landfills and simplifies decommissioning or relocation of solar module systems.

Q:solar panels?
answering b) your home circutry won't be able to handle solar power energy (or your circut breaker,it will start cuttin out every 5 min)you would have to replace your home circutry(that costs a LOT of money, over $8500)
Q:Solar Panels: How long will it be before solar panels are cheap & effecient enough so that everyone?
As the cost of fossil fuels continues to rise, solar panels become of more value. At one time they were looked on as a rather expensive investment with only a long-term pay off. Now oil is so expensive other sources of power such as wind, solar panels and geothermal energy become relatively cheaper. The efficiency of solar panels is expected to rise so that even in regions where sunlight is limited, these become a realistic investment.
Q:how do buildings circulate energy?
The answer depends upon the type of solar energy captured . Photovoltaic Solar Panels convert the energy into electricity. This electricity is ran throughout the building via wires. Thermal Solar Panels typically capture the energy in the form of heat. The hot water is circulated through the building in water pipes.
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:can you hand make a solar panel?
The idea is to hand assemble scrap solar cells that would otherwise be thrown out. At one point in time, very few people would want to do this so you could get the broken solar cells for free but now they sell them by the watt. It's still cheaper than a pre-fabricated solar panel but it's very labour intensive. Technically it's like wiring a bunch of batteries together, you measure the voltage and current a broken cell produces and decide whether or not to wire it in series or in parallel with other cells to get the performance characteristics that you want plus try to fit them onto some kind of structural panel in a fashion that uses the space efficiently. Since your handiwork is likely to be fragile, you'll probably have to put some plate glass on top to protect the cells from the elements, you can also improve performance by positioning fresnel lenses to increase the amount of light on active elements versus inactive areas of the panel.
Q:Does the new horizons has a solar panel for it power resources instead using nuclear generator?
No solar panel, and for the reason you stated - it is so far from the Sun that a solar panel would be of little use (and a lot of extra weight) at the distances where the primary part of the mission was being performed. The power source is called an RTG. We can think of it as similar to a nuclear-powered battery or a miniature nuclear power plant. As far as I know it is not intended to reach any other star. If it does, it's power will have long since depleted - and it would take thousands of years at its current speed to reach even the closest star. Closest star: Proxima Centauri, slightly more than 4 light years away. Current speed of New Horizons relative to the Sun: 4.52 km/s That's 0.000048 of the speed of light. It would take more than 20,000 years to reach Proxima Centauri *if* it were heading in that direction (which it is not).
Q:What is the main material for making solar panels?
You can also according to their own needs, according to the power to buy a good package of solar photovoltaic products.
Q:How do you get electricity in a rainy day if you have solar panels?
You okorder.com/
Q:are flexible solar panels possible?
Yes it depends on the material of the bearings fixed, on the to be Moved pivots!/--Fulcrums/turning points/hinges.etc. but the wiring for commands has to reach them keeping them moveable in unhospitibale temperatures.The heating effect of an electric current is benificial too.
Q:how effective & efficient are home made solar panels?
I had a system installed recently, so I would suggest starting by getting a quote from a licensed contractor. Even if you are planning on doing the installation yourself, a contractor will have a lot of useful info. I got 3 quotes and they were all about the same cost. I was able to get a 2 year usage history from our utility so the contractors were able to suggest a system based on that. They were able to tell me about rebates and tax credits, were the best location would be and the estimated amount of production. They have a nifty gadget that can tell if there will be any shade cast on the roof at any time during the year. I decided to maximize my rebates and got a system that reduced my utility bill by about 50%, although my production has cut it much more than that, my highest electric bill was $35, and that was in Dec. with cloudy short days. I got a $0K rebate and a $2K tax credit. This year the fed. tax credit is 30% of the total installed price. My system cost $26K, I paid $6K out of pocket and I'm saving about $2K per year.
