Q: What is the average payback period for solar panels?: The average payback period for solar panels is typically around 7 to 10 years. However, this can vary depending on factors such as location, system size, local energy rates, and available incentives.

Q: Is there any way to charge my laptop with a solar panel? Is there any panel like that. Or if I work on panels can I do something like that. If you know anything about it, can you just help me? Thanks a lot.: Deep Cycle Series batteries are designed to have a large amount of stored current discharged between charging sessions, with very heavy non-porous battery plates to withstand repeated major discharging and charging cycles (deep cycles). They are typically used where the battery is discharged to great extent and then recharged.

Q: Photosynthesis is fairly inefficient, but efficient enough to power all life on earth.: Silicon is a very good conducter. Probably the best for electricity.

Q: If a solar panel is a .5kW system, what length of time is it putting out that much power? Every hour?: I think it refers to the maximum power it is capable of. Of course, it won't really have this output because it's energy output (kWh) is dependent on it's energy input...

Q: Are there any fire hazards associated with solar panels?: Yes, there are potential fire hazards associated with solar panels. Although solar panels themselves do not typically catch fire, electrical malfunctions or faults in the wiring, inverters, or connectors can lead to overheating and fire. Additionally, if a fire breaks out in the surrounding area, solar panels can hinder firefighting efforts by creating potential electrical hazards and obstructing access to the roof. Therefore, proper installation, regular maintenance, and compliance with fire safety regulations are crucial in mitigating these risks and ensuring the safe operation of solar panel systems.

Q: I have created a solar setup in my shed i have 2x.5w solar panels i am hoping to charge my 55ah car battery how long would it take to charge the battery and how many watts could i used a day: I don't think so, but if it did, it would take a very long time. You need enough wattage or amps to push the power in the battery and 3w may not be enough. You would be better off with a small 2v battery, maybe the type they use for emergency lights. I would use a sealed battery for this type of setup because car batteries are designed for heavy charging with alternators from 60 amps and up.

Q: am having a 75 watts siemens solar panel and is giving me 2.89volts during bright light, i wanted to know can this be used to charge 00Am/hr battery?: Many of the panels used on homes are designed to produce 2 volts DC. 0 of them wired in a series would produce 20 volts DC. An inverter is used to change the DC voltage to AC. The other aspect of electricity is amperage. With electrical units wired in series the voltage is added. When they are wired in parallel the amperage is added. The Volts x Amps produced will give you the wattage. A wise homeowner will examine their electric bills or the equipment used to determine their demand. They will consult tables that let them know how much sunlight their area receives each year as this will alter the rated performance of the panels. Then they will try and determine how much of the demand they want to fill. 80% may be economical. Then they also want to determine what they will do with excess electricity that may be produced during the summer months of intense sun and how they will supply the shortfall of low sun winter months. From all this they will determine the number of solar panels they need to purchase.

Q: Can solar panels be used for heating a greenhouse?: Yes, solar panels can be used for heating a greenhouse. Solar panels can generate electricity, which can then be used to power heating systems in a greenhouse. Additionally, solar thermal panels can directly capture the sun's heat and transfer it to the greenhouse, providing an efficient and sustainable heating solution.

Q: I am going to be building green in the next couple of years and i need an idea of how many solar panels i need in addition to a wind turbine to sufficiently handle a workshop, house, green house, etc. and what the approximate cost will be.: Solar panels will come down in price each year from now on.. so any price now would not help you much. I just bought a panel for $00... What you have to compare is the type, output, size, durability, warranty, and other features.. The prices vary a lot, depending on these variables. Another option you may want to consider is just buying green power from a provider. Texas and New York now allow this... Other states will deregulate soon I hope.

Q: Okay, so I have a science fair coming up soon and I need help with my project. SO - What should I use to demonstrate with the propeller? A toy boat? Plane? And I only have mini solar panels ; so how do I put the solar panels on the toy boat/plane to make the propeller move off of the sun's energy? Thanks. Steps please!: Solar panels produce electricity. To move the propeller you need mechanical motion. An Electric motor converts from electrical to mechanical power. Most Solar Panels produce DC electricity as do batteries so you need a DC motor that is sized to match the Output of your solar panels. For small temporary projects like this I find that hot melt glue is great to assemble parts. Using a voltage meter you can expose your solar panels to a strong light (or one equal to what you expect during your demonstration) and measure the voltage across the terminals. This may help to size the motor. It depends upon the size of your propeller and how it is made. Your three choices are to use it to power an airplane, to power a boat underwater or to power a boat like an air boat. You might also use the air boat concept to make a car. (air car) The air boat might be the simplest to make but you will need a body of water to demonstrate the concept. The air car doesn't have such a requirement.
