Q:Solar panels and your opinion?
I have a boat in a sunny position and four eighty watt panels. These will run my fridge television and a few LED's. I nonetheless need to run my engine for sizzling water and washing desktop. My Batteries only final a couple of years and are an actual affliction. I am going on the mains when i will be able to to get the batteries topped up. The panels are adequate if there's nothing else, they don't seem to be the answer to the way forward for power provide. There's additionally the ethical part of the feed in tariff. For the wealthy to load their electrical power bill onto the less good off just isn't desirable and those panels on the roof inform all of your neighbors that you are doing it. As a way to exhibit a grasping selfish attitude. If they're any just right why don't the vigour companies purchase them and shop shopping coal?
Q:How can I make a sun tracker for a solar panel?
tbls0 has a good idea for the tracker, but let's take this one step farther. A clock motor large enough to move a solar panel, unless it is a very small one is going to be large, and expensive. Use the timer motor, as suggested, but attach a slotted disk to it, with a light source on one side, and a detector on the other side. As each slot comes up and allows light to pass through, this creates a one shot pulse which is used to cause a stepper motor to move position to keep the panel aimed at the sun. At the end of the panel travel for the end of the day, a switch could be set to close, bypassing the step control to put the motor into full constant speed reverse, this causing the panel to swing back to the morning position. The whole affair gets it's start up call by means of a light detector, similar to those used to turn lights off at sun up. The control would, of course be set to turn the system on to track the sun during the day. While some digital control is going to be needed, the system would not need a computer to run it.
Q:Why only Photo-Voltaic solar panels?
Solar thermal systems aren't really that much cheaper. You have to have complex systems to pump the water, heat exchangers, regulate the temperature in the panels so it doesn't get too hot, regularly inspect it for leaks, have a system to maintain a constant output temperature, etc. The return on investment of such systems are usually very long, on the order of several decades, even for very large buildings. If they were cost competitive with traditional heaters then they would already be much more widely used I think. Plus with solar thermal you have the unfortunate reality that technologically they aren't going to get much more advanced. That's probably not the case for PV panels. So the only way I can really see solar thermal being used on a larger scale would be some kind of subsidy. PV on the other hand may have a breakthrough tomorrow that drastically reduces its cost. I'd be curious to find out how well those solar AC units actually work though, I can see how they might have potential.
Q:What solar panel do I need?
Are you saying your house continuously draws about .5 kW average all day long? That's 36 kWh per day, if so. This is about double what our house uses year-round, so if you lived in our area, that would be a 6 kW system. The only way to nail down a good number is to get a quote from a local solar installer, though.
Q:You place four identical solar panels in 4 places.?
probly the sahara desert since it there's not much rain there which would equal few clouds. you'd get plenty of direct sunlight. the moon is constantly orbiting earth and in different possisions with the sun which would equal less sun exposure.
Q:How much do solar energy panels cost?
The price of solar systems have dropped dramatically in the last 5 years. I would say it has reached to the point that it financially makes sense to go solar! An average home in [California] with $200 monthly electric bill would need a 7.25 kW system to offset 00% of their electric bill (means you won't have to pay anything to your utility company). Average price of the panels are anything between $2,500-3,500 per kW (after 30% Federal Tax credit which might expire at the end of 206). So, average system price will be $7,000-$25,000. If you wanna buy the system your loans monthly payments will be around $40-50 for 2 years and after that your system is paid off and you can enjoy free electricity! Total saving over 25 years can exceed $70,000. Regarding the selection of the right panels or the best company in your area, it varies case by case, city by city. Pick My Solar offers a free service to homeowners to choose the right fit for their home. It's like Expedia or Priceline for residential solar market.
Q:Where can I get free solar panels?
I did the same thing recently, if you'd really like some free ones then you need to look for those little solar powered lamps that people put in their yards, theyre about 0 inches tall and people sometimes line the paths through their yard with them. Maybe you can find a neighbor who doesn't want theirs anymore, or you could check local dumps for them. They each have a solar panel in the top, and they can be linked together to make more power. Alternatively, you can look on OKorder for a pack of broken solar cells, which still work fine but don't put out quite as much power as they did when they were new. However, they are very cheap. Hope this helps.
