Q:I have a question about solar panels?
Read this link.
Q:Why don't scientists use the design of a tree for solar panels?
solar panels do not use generators, but i like your idea, very creative.though i don't see the practicality of this being used commercially, i think it would make a great solar promotional piece though! off-subject, it is time we stop looking at the upfront costs of things and start looking at what the long term costs are. most green-technology, although expensive at first, end up saving tons of resources and actually increase profits of businesses! studies show that people who work in a green building tend to be happier which benefits health, more excited to go to work due to the business's environmental ethics, are more productive because of natural lighting, and are more efficient because more work is getting done. green buildings can actually boost the efficiency of a business! thus saving tons of money and reducing tons of waste. Doesn't this just make sense to you?
Q:Calculate solar panel energy output question?
You have the area of the solar panel. You know their efficiency. What you need to know now is the energy (per area) delivered by the sun. The energy delivered by the sun can be found on the internet. Earth ,43 – ,32 W/m² (wikipedia) That is offcourse for your solar panels perpendicular to the ray's of the sun. If they are under an angle you should see what the area of the projecton of your solar panel is on a plane perpendicular to the ray's of the sun. So know you have the intensity W/m² and an area (or effective area). Here you go the energy deliverd by the sun. And 30% of it is what you get out of your panels.
Q:How to maintain a battery with a solar panel?
What I would suggest is that you find a panel that is rated for 00 mA, at any voltage higher than 8 volts. A 2 or even 8-volt panel will do, because the voltage will drop to match the battery. Then I would get a diode to put in series with the panel to prevent the battery from discharging through the panel at night. That's called a blocking diode. At such low currents, a charge controller is not worth it. There is not enough power to overheat the battery, which is principally what a charge controller protects against in a larger system. Be aware that you could also simply plug a trickle charger for the battery into the wall outlet, at a cost of less than a penny a day in electricity.
Q:Are solar panels a good idea in Seattle Wa?
The solar rating of your area is Good so I wouldnt see the reason not to use it. In my area solar rating is very good I get all evergy from it plus even selling it. My payback time was very quick but... If you are not in a hurry or cant afford to spend a lot, wait till end of the next year when the new flexible panels are coming to the market. They are suppose to be a lot cheaper, enviromental friendly more effective than the ones on the market now. Check out MY Estimator. I think for USA users its the best help on the net. You'll see your costs, tax incentives can get info about local PRO's aswell. Often people are shy to ask quotes but solar is overpriced at the moment so spend your time finding the best deals. Also check where panels are made, their efficency; warranty is usually 20 to 25years. Surf the net- OKorder, OKorder then check companies who sell solar panels. Some even offer price fix if you see other place selling with better price. Good luck!
Q:What is a good type of solar panel to get for my house?
solar panels are VERY heavy and can be very complicated, youll need a professional. your roof may need to be reinforced to handle the weight added. some states like Arizona will pay for the system for could use solar power to heat the water in the house and everything else off the power company. if you do, get one with a glycol heat transfer solution. they heat more efficiently.
Q:Has anyone had roof problems caused by rooftop solar panels?
Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.
Q:Solar Panel?
Though wind energy is the big thing at present, and I derive a significant part of my income from doing engineering on these wind farms, I personally prefer a wood-fired boiler steam turbine generator combination as the best renewable energy system. Wind generation works great when the wind blows, but if you intend to go off-grid expect to invest in energy storage and some other form of backup power. Solar photovoltaic panels are about 6% efficient at best, and that's only when the sun is shining brightly. If you consider that trees (biomass) are a completely natural, renewable energy resource, and couple this energy resource with modern clean combustion technology, this makes for a great dispatchable, long-term sustainable, ready-when-you-need-it solution. Go wood!
Q:Solar Panel Help, Trying to go green.?
LOL!! There is a lot more to this than you might imagine. This is a very rough approximation but look at the attached and column labeled 6.3KW. Look down that column and you see where it says Est. First Year KWH Generated ,025. So if we were to assume that each month it will produce ,025/2 kwh. (not true for January but I am trying to keep this simple. The installed price without any rebates is $44,050. ;-) Sorry! You will find some a little cheaper... some a little more expensive but none are a LOT cheaper than this. (this price does not even include energy storage, so the sun goes down and you will stop producing electricity). This is why, when people start looking at this sort of thing, they always do what they can to conserve electricity first. It is always much cheaper to conserve, then worry about alternate energy.
Q:Solar Panel questions...?
I have a system that was installed last year. I have 20 panels which provide me with about 75% of my electricity. I do use less electricity than the average home. I use an average of 45 kwh in the summer, my neighbor uses more than double that. I paid $26K for the system, but I got a $0K rebate from my utility and the US gives a fed. tax credit. I am saving about $2K per year, so it will take just over 6 years to break even. I also have what I think is called net metering, my utility allows my meter to run backwards when I generate more energy than I use, so pretty much the entire time the sun is out in the summer. Having energy efficient appliances, reducing standby energy and using conservative climate control really helps keep my usage down. Weather striping, insulation and clean well maintained systems all help as well.
