Product Description:


Roof-mounted solar power systems consist of solar modules held in place by racks or frames attached to roof-based mounting supports.

Roof-based mounting supports include:

    Pole mounts, which are attached directly to the roof structure and may use additional rails for attaching the module racking or frames.

    Ballasted footing mounts, such as concrete or steel bases that use weight to secure the panel system in position and do not require through penetration. This mounting method allows for decommissioning or relocation of solar panel systems with no adverse effect on the roof structure.

    All wiring connecting adjacent solar modules to the energy harvesting equipment must be installed according to local electrical codes and should be run in a conduit appropriate for the climate conditions

Solar panel conversion efficiency, typically in the 20 percent range, is reduced by dust, grime, pollen, and other particulates that accumulate on the solar panel. "A dirty solar panel can reduce its power capabilities by up to 30 percent in high dust/pollen or desert areas", says Seamus Curran, associate professor of physics at the University of Houston and director of the Institute for NanoEnergy, which specializes in the design, engineering, and assembly of nanostructures.

Q:Wanting to add solar panels to my home?
Ok, well there are also other alternative energy sources, too, besides solar. There is tidal (but you need an ocean :] ), hydroelectric (river, stream, etc.), biomass/biofuels (burning garabage), geothermal (from within the earth, pipes in the earth), wind (windmills, wind, the sun to get wind), and there are others that don't come to mind. Solar energy would cost alot to be installed, and it would take up alot of space, but once installed it pays for itself and uses little to no labor. They all have positives and negatives. All of these are clean and renewable. Here are some sites that my teacher/professor gave us (we just ended alternative energy lesson.) Well I hoped this helped!
Q:Tips for convincing my school to put solar panels on the schools roof?
When okorder.com/ Good luck but the best way to win is to find a way to get it done and then they can't say no.
Q:Why only Photo-Voltaic solar panels?
I agree with you John and for the same reason already put forth as a negative. Solar thermal is a more mature technology. This is the reason why I spent so much of the last winter studying it. I can be reasonably sure that what I learn will not be obsolete tomorrow with a new technological breakthrough. I built a solar addition/greenhouse to personally study the effects. So solar thermal panels are not the only way to go. With respect to electrical production. I have seen parabolic reflectors coupled to stirling engines and solar thermal trough heaters used to supplement steam generation for alternatively gas fired steam / electrical generation plants. On a trip to China over 4 years ago I noticed solar hot water vacuum tube collectors being sold in their local hardware and big box style stores. These were gravity fed package units intended to have the tank on the roof with a supplemental electric backup. The vacuum tube collectors seem to be one of the latest innovations in this technology. Using phase change materials temperatures in these panels can be produced in excess of 400 deg F. and they are useful in colder temps and on cloudy days. While they are still costly for many applications, I have been discussing the use of vacuum tube collectors with the owner of a laundrymat. Solar thermal will not pay back as well as conservation in many cases of older construction, but it currently seems better than photovoltaic panels. Solar thermal requires more understanding of systems and relative efficiencies. In one way solar thermal is more like the electric car while the internal combusion engine is like photovoltaic. The idea of producing electricity from the sun is a sexier idea. It is also more in line with our paridigm of: just producing lots of energy and to H with any conservation efforts. For that reason it seems to get more press.
Q:solar panel inverters?
definite, the inverter ought to pull potential from both the battery and photo voltaic array, yet so what? that would favor to not be a project. both the potential from the photo voltaic array receives kept contained in the battery, or it is going on to the inverter, what vast difference does it make? in reality that's more beneficial effective to pass on to the inverter, as battery value/discharge cycles waste quite some potential. yet you desire a fee controller between the panel and the battery and which will regulate the present into the battery to maintain away from overcharging, and also regulate the voltage and contemporary to right value the battery. without it, the output from the array will be too intense for the battery, or too low. .
Q:How to hook up a Solar Panel To a single outlet?
That solar panel puts out about amp (in round numbers). If you are talking about a 20vac outlet, you'll have to send the output of the solar panel through an inverter. That brings it up to 20vac. 20 watts at 20 volts means you'll only be able to draw 0.6667 amps. With an inverter at 85% efficiency, you'll only get about 0.4 amps. That would barely light a CFL. 20 watts of power at 7 volts = amp (in round numbers) 20 watts of power at 20vac = 0.6667 amp (in round numbers) Power (watts) = current x voltage. If you increase voltate, you must decrease current to get the same watts. Watts is the common denominator in power measurement.
Q:what are solar panels?
Solar okorder.com/
Q:Can I made my own solar panel?
If you're thinking of solar electric, unfortunately, it's not cost-effective to make your own panel. Be especially wary of scams like Earth4Energy that claim you can do it cheaply and effectively. If it was so easy, you'd see at least a few people in your neighborhood doing it.
Q:Can you make a Solar Panel Heater?
Absolutely. But I see your point about the Ohms law. I think you'd need technical schematics to get the raw details.
Q:i have three 30 watt solar panel and 6 battery cells of 2 volts 550AH. but my batteries are never fully charg?
you need to have a voltage regulator on the gadget. That suggested, i imagine you're literally not giving it sufficient time. The battery might want to convey the voltage all the way down to its element. it is merely you attempt to replenish a huge reservoir with an eye fixed dropper. Bringing the voltage down would not help both. That lowers your ability.
Q:what is a solar panel?
A panel that is attached to the top of a roof of a house that converts the suns rays into electrical energy that can be harnessed and used to power appliances, light rooms etc. through silicon particles.
