Q:Any drawbacks for solar panels?
The largest drawback is the upfront investment you have to make for solar panels. There are some programs that allow you to finance the panels through your property assessment called PACE and leasing programs that can alleviate the large upfront cash outlay. Solar Panels have a lifespan of 30+ years. Since there are no mechanical parts, there is very little maintenance required. After 0-5 years, you will have to replace the inverter which converts the energy from DC to AC. This is a small cost in respect to the whole installation. The panels clean themselves well with just normal rain. With all the great federal and state incentives, the payback on solar is at it's all-time best. In Massachusetts, for example, the payback right now is 5 or 6 years -- then you would be making money for the next 25+. Another big potential drawback is that you must have the right site for solar to begin with. I'm a solar installer and I can tell you a lot of houses might not be right for solar. The best orientation is south, while southeast and southwest can work as well. The space must be unshaded and it would be best if it had few obstructions like chimneys, etc.
Q:What home appliance can be powered by a solar panel?
Simple answer. Anything you can power with your normal household electric can be powered by solar. So you know what a solar panel is: A solar panel is more then one solar module mounted on a frame to be installed as a single unit into a solar array. Next question is normally what is a solar module: A solar module is a bunch of solar cells mounted together with a clear front and a white backing. Solar is something that you install on your home so you don't have to rent electric power from the public utility. It has a large upfront cost but will pay it's self and you then own something. Like if you rent a home you end up with nothing but if you buy a home you pay a big upfront payment and in the end you own it and can sell it for a profit. Yes you can run your A/C unit from Solar Electric. As said above. Anything you can run from the pubilc utility can be ran from solar. If it is in your home and running from electric right now you can run it from solar.
Q:Is photovoltaic array another name for solar panels?
Yes or one could say that Solar Panel is a simple and easy way to say photovoltaic array.
Q:Need Solar Panel Guru.....?
With your load, the largest system on the page I reference above would not power your entire house, if all the AC units are running. However, how often does that really happen? You need to look at your utility bill and find your actual amoutn of KW hours of electricity used in a year and you hav enot told us that. The base price of top system quoted here without incentives is over $70,000. As you can see, the lions share of incentives is the utility company followed by federal. I have no idea if your local utility company offers incentives or not. You would have to resolve that with them. However, the federal incentives are still there even if your state and local utility has none. However, the price to you goes way up without all of these incentives. And your idea of using windows to mount solar cells is totally impractical. Yes, I know there are web sites that advertize just that, but it is total BS. The first word of advice to anyone looking to do this sort of thing is to FIRST have a complete energy audit done and then do whatever they say to conserve as much energy as possible, thereby reducing your need for solar power. Only then should you look at using solar to cover part of your load. We are a foster family and have adopted 5 children< WOW! I would like to thank you for what you do.
Q:solar panels in space?
You do realize that the sun is 50 million km away don't you?
Q:so i'm wanting to eventually get solar panels.?
Graminoids are among the most versatile life forms. They became widespread toward the end of the Cretaceous period, and fossilized dinosaur dung (coprolites) have been found containing phytoliths of a variety that include grasses that are related to modern rice and bamboo. Grasses have adapted to conditions in lush rain forests, dry deserts, cold mountains and even intertidal habitats, and are now the most widespread plant type; grass is a valuable source of food and energy for all sorts of wildlife and organics. Graminoids are the dominant vegetation in many habitats, including grassland, salt-marsh, reedswamp and steppes. They also occur as a smaller part of the vegetation in almost every other terrestrial habitat. There are some 3,500 species of graminoids. Many types of animals eat grass as their main source of food, and are called graminivores – these include cattle, sheep, horses, rabbits and many invertebrates, such as grasshoppers and the caterpillars of many brown butterflies. Grasses are also eaten by omnivorous or even occasionally by primarily carnivorous animals. In the study of ecological communities, herbaceous plants are divided into graminoids and forbs, which are herbaceous dicotyledons, mostly with broad leaves.
Q:Could solar panels contribute to global warming?
apparently okorder.com/ <== this is a more lighthearted link. so the problem is not, what color stuff is. the problem is, how much energy can the planet lose? as far as the solar panel, consider, if that same amount of energy fell on the roof, some would be reflected and some would be absorbed. if it falls on a solar panel, some of the energy will get converted to electricity. so there will be less that needs to be radiated and lost. therefore, when they're working, solar panels, even though they're black, produce cooling.
Q:Need some Information about solar panels ?
No. The only coatings I am aware of are those that reduce reflection so more light gets through the protective surface to the actual cells. Anything thing that affects appearance is going to be reflecting light back to the viewer and the photons of that light are not available for electricity or heat. If the appearance of the panels offends you, then they need to be concealed by a fence of panels around them that do not throw shadows on the panels.
Q:Solar panel setup?
You have to keep the polarity straight. Red is positive + Black is negative - I don't know how much amperage you are drawing, or how many amps the solar panel puts out. This charge controller is a device I am unfamiliar with- What does it say on it? how many volts? how many amps?
