Product Description:

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.

Q:Solar Energy - What would these solar panels power?
note breath on the winds excellent answer is one quarter of one percent. See why houses aren't covered in solar panels? it's just not a real answer right now,. the rough rule of thumb is $0 per kWh ( for just the panels) you want to produce. You'd need $20,000 in panels and another 0,000 in controllers and inverters and batteries and who knows how much in installation.
Q:how to make your own solar panels ?
I did my own solar panel at a fraction of a commercial one by diy manual. I think some of the important criteria to consider about these diy manual are : . is it proven by many of its readers ? 2. How easy to follow the manual ? 3. Any video showing the steps to assemble your own panel ? 4. Any after sales support ? You can cut down your electricity bill on some small appliances like your labtop or fans, but not practical on heavy duty appliances like air-cond, etc.
Q:how fast does a 25watt solar panel generate power to a battery?
To figure our how many you need, take a look at your power bill. It will tell you how many kilowatt/hours you used during the month. My bill says I use about 2000 kilowatt/hours per month, or about 2000 kwh /30 days=67 kw/h hours per day. That is 67,000 watt hours. To supply that with solar panels, you have to generate at least 67,000 watt hours, but you don't have a full day to do it, since you have to do it while the sun is up. So you put the energy into batteries during the day, so you can use it at night. A 25 watt panel generates about 25 watts when fully illuminated by the sun. If you fully illuminate it for an hour, you get 25 watt hours. If you get 2 hours of sunlight a day, that would seem to imply that I need 67000 watt hours/25 watts /2 hours=45 panels. But for most of the day, the sun isn't hitting the panel fully, so it isn't going to generate the full 25 watts. When the sun is 45 degrees to the side, you only get about 70%. When the sun is 60 deg to the side, you only get 50%. And what do you do on cloudy days? And the shorter days in the winter? To make up for this, you have to increase the number of panels to make up for the loss. So in reality, I might need double this number of panels, for realiable solar power throughout the year. That works out to about 90 panels, or ,250 watts worth for my house.
Q:Question about solar panels?
Good question. Something to keep in mind is that modern solar electric works _alongside_ the grid, so you don't need to displace your entire 2300 kWh. The best financial return, if any, might come at a point where you generate only 500, 000, or 500 kWh per month. How many panels you need strongly depends on your location. Speaking for the location of my house in San Jose, Ca, that amount of usage would be about a 2 kW array, and if you divide 60 into that, you get 200 panels. In a perfect location, you would need slightly less, in a northern state, you might need double that. If this was a real project, you would probably not use 60-watt panels. The choice of panels is not simply a matter of getting enough watts. 2 kW is a large system today for residential. The usual advice is to go for energy efficiency first, then consider solar after the usage is down.
Q:Home solar electricity advice? Making the solar panels accessible?
Modern solar electric panels rarely fail. Because of this, if you would be installing them over a roof that only has a few years left on it, it would be better to redo the roof, first. In the unlikely event that a panel needs to be changed, this can be done in 30 minutes or so, because the panels are mounted on racks, with everything simply plugging together. I have never personally seen a solar installation go bad, but from what I hear, the inverter (a box that goes in next to your electric service panel) is usually what burns out after 5 years, assuming the install was done right in the first place. If you were to call roofers to repair your roof, they would somehow be able to get to your roof, by ladders, or a special truck. Solar installers use the same kind of equipment. They won't have a problem getting up there. A solar electric system is actually a very straightforward thing. No matter who installs it, if there is a problem, another installer should be able to diagnose and fix it.
Q:How much for a 8kwh solar panel system?
Figure 8 hours of sun per day, so 8 kW-hr is a rate of kW, which is a medium sized panel, probably not enough to operate your house totally, unless you have a very small unit. Averaged over 24 hours, that is power at a rate of only 300 watts, enough for a TV. Average US home use is .2 kW, which over 24 hours is 29 kW-hr, plus you need extra for cloudy days, peak demands, and to charge batteries. You have to decide off-grid or on-grid, and if you want to (and are allowed to) sell excess power to the power company. Off gird, the cost of batteries and charge controller are a large part of the cost. On-grid, you have to purchase equipment approved by the power company to match your power with the grid. Panels will cost about $3 per watt, so for 000 watts that is $3000. Double that for installation, then add in cost of charge controller, inverter, batteries, etc. The last items depend on your alternatives, see paragraph above. .
Q:Best orientation for my solar panel?
It doesn't make sense to me. I am at latitude 37.7,and my panels face south at about 38 degrees. Yours should be pointed north as you suggest. Being so close to the equator, and in the absence of any better information, an angle of 2 degrees would be appropriate. However, choosing the best angle will greatly to your overall efficiency, so I would try to find a more credible source, How about the folks from whom you buy the panels. They would know precisely. By the way, if you haven't installed the system yet you might consider going to a high voltage system to cut known line losses in the conductors between the panes and the inverter, I did that plus increasing the conductor size over that recommended by the manufacturer. I gained about two percent in efficiency
Q:Does anyone know a good company to buy solar panels from?
Guide okorder.com/
Q:Designing 3d Solar Panels?
I don't know anything about the 3D thing. You cannot get more energy out, than goes in. Energy will only hit the mirrors. With some loss of efficiency they would reflect a focused beam into the chamber, where with some more losses would reflect it to the solar panels. It would be more efficient just to expose all the panels to sunlight.
Q:Can a solar panel be used as a NiCd cordless tool battery charger?
Your 5W solar panel has to put out about 5 volts or higher to charge a 2 volt battery. 5 watts at 5 volts is only 0.3 amps, which is only enough to handle the internal leakage inside a large battery, plus a bit. If you have a 00 amp-hour battery, that panel would take 300 hours of bright sunlight to charge it. But I do agree that it will keep the truck battery charged as long as it gets sun. Make sure you put a diode in series between the panel and the battery to prevent the battery from discharging through the panel when the sun goes behind a cloud. I'd be worried that if you charged the 8 volt battery frequently, the panel would not be able to replace the lost charge, and your 2 volt battery would wind up discharged. That 8 volt battery is .2 amp-hrs (if I got the correct one). That is 27 watt-hours. Allowing for losses, you car battery will have to deliver over 30 watt hours to charge it. Your solar panel will take over 6 hours of bright sun to make up that difference. That is over 24 hours this time of year. So if you recharged it more than once every 2 days, you will lose charge in the truck battery. .
