Q:i just took a trip to florida, they are cutting down anything that doesnt float and putting up buildings. Most of these cost a bundle, bill gates may pay cash for them, but most people will have many payments. Since pools, satellite dishes, and docks if near the water seem to be standard issue, why not a couple solar panels and water heater. It is florida after all, and if you are allready paying a half million or so for a house, what is another 0k gonna mean to you. Why dont they make it mandatory to include these on all new housing and condos and businesses. With that many the price would come down quickly and pay for itself long before the house is payed off and/or florida is flooded due to global warming.: Solar Panels in housing developments is not being used because it would add $25,000 to $40,000 to the price of the home. Most people in the USA don't understand that after a few years the solar electric panels will start paying them back. It is not just the upfront cost. People would rather spend that 40K on somthing smart like a new corvette. Which has no pay back at all then something stupid like solar electric and helping themselfs or the rest of the world. So if the builders were to add them to the house people would just buy from another builder and the one adding the solar roof tops would just go broke. The State would have to find a way to credit the buyer or buider enough to make it worth it. Is it not more fun to spend millions on finding out where Anna Smith is going to be barried? Or maybe billions on top of billions on War? If we had spend the money on solar that we have spend on Iraq alone we could have put solar on every roof top in the whole USA and had few billion left over. Think about it.. 200 million people in the USA with three to a home would be 66 million homes. It would have only cost 528 billions dollars to put a kWh Solar Electric system on each house in America. But that would be stupid. War makes more money. We don't want Exxon to go broke do we?

Q:I am looking to wire in some solar panels into my home. I already have plenty of wiring, and some solar panels around. I just need to know what I need to do to wire them into my home so I can lower my electric bill. This past month it was six hundred dollars.Can someone direct me to some information, or tell me how without telling me to hire some guy to come out to charge me thirty thousand dollars to install two or three thousand dollars worth of equipment?: I am all for do-it yourselfers, I am one, but... Sorry to tell you, but connecting solar panels to grid power will require an electrician. There are many requirements for special disconnects to prevent harm to the utillity company workers that must be considered. You will also have to have an inverter sized to match your panels. The simple answer is to connect your panels to something specific, without connecting it into your house wiring. An example is to connect your water well pump to solar power and disconnect it from the grid. But you will still need an inverter and will need to calculate the power demands of the pump and the amount of power available from your panels, which varies by your longitude and latitude. It sound like a simple thing to do, but without special training and experience you will be sorry if you try this yourself.

Q:Any opinion on harbor freight solar panels ?: I bought my first set 8 years age and the 45 watt set finally gave up the ghost last week. I have another 45 watt set 3 years old and has maintained 4 2 v deep cell batteries at 3.5 to 3.8 volts for the last 3 years. I have them on my cabin and use them mainly for lights and TV. but with my 2000-4000 watt inverter runs the microwave nicely.

Q:How often do solar panels need to be replaced or repaired roughly? Is it costly to do so?: New solar panels are clean and shiny and they look cool. Then they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Solar panels must be regularly cleaned and maintained in order to keep them operating efficiently and maximize the amount of sunlight they convert into electricity. Unlike windows your solar system needs to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be. Solar panels will attract dirt, dust, soot, pollen, tree sap and salt crystals in coastal regions creating a fine layer of grime. This layer reduces the amount of light reaching the silicon cells under the glass surface and reduces the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be. Some have reported a ten to fifteen percent loss of solar output due to dirty panels. From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerable reduce its effectiveness. See much more about solar panels maintenance below link

Q:Is there a cheaper way on how to make your own solar panels ? Can someone share their real life experience ? Thank you.: There are several things you’re going to need when making a homemade solar panel, some of the main components include: Solar Cells Wood Plate Soldering Iron Solder Tabbing Don’t worry; special tools are not required for this DIY ‘solar panel’ project, and you will probably have everything you need laying around the garage. and just bind them together.

Q:How long does it take to recoup the cost of solar panels through energy savings?: The time it takes to recoup the cost of solar panels through energy savings varies depending on factors such as the cost of the panels, the amount of sunlight in the area, the energy consumption of the household, and available government incentives. On average, it can take anywhere between 5 to 20 years to recoup the initial investment. However, with technological advancements and decreasing costs of solar panels, this payback period is steadily decreasing, making solar energy an increasingly attractive and financially viable option for many homeowners.

Q:Are there any government incentives for installing solar panels?: Yes, there are various government incentives available for installing solar panels. These incentives can include tax credits, grants, and rebates provided by federal, state, and local governments. These programs aim to promote the adoption of renewable energy sources and help reduce energy costs for homeowners and businesses.

Q:Solar panels single crystal and double crystal in the rain which is easy to use: At present, monocrystalline silicon solar cell photoelectric conversion efficiency of about 15%, the highest reached 24%, which is all types of solar cells in the photoelectric conversion efficiency of the highest, but the production cost is so large that it can not be a large number of extensive And commonly used. Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.

Q:I have several 6v 4.5a sealed lead acid batteries. I would like to hook one of them up to a solar panel and have it stay charged from the solar panel all the time, but not overcharged. Is there a simple way to do this with an IC or something? I am only a beginner with circuits so I want it to be something very easy to make. Basically, I want it to stay charged all the time so it's available if I need it for a power out or something.Thanks.: 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:Can solar panels be used to power a theme park?: Yes, solar panels can be used to power a theme park. Solar panels can generate electricity from sunlight, providing a sustainable and renewable energy source. By installing a sufficient number of solar panels, a theme park can meet its energy needs and reduce its reliance on traditional power sources, contributing to environmental sustainability.
