Q:okay so my teacher is trying to install a solar panel but we have a problem we don't know where to ground it because it will be a movil house. guys do you have any ideas?: Typically you mount it with the frame as a ground and you ground the frame with a wire or cable tied into the ground when the mobile home is parked.

Q:How do solar panels affect insurance premiums?: Solar panels can potentially lead to a decrease in insurance premiums as they are considered to be a low-risk investment that adds value to a property. However, the exact impact on insurance premiums may vary depending on factors such as location, system size, and the insurance provider's policies.

Q:How do solar panels affect the roof's lifespan?: Solar panels can actually extend the lifespan of a roof. They act as a protective layer, shielding the roof from the elements, such as UV rays, rain, and snow. This helps to prevent damage and deterioration, ultimately increasing the roof's longevity.

Q:Can solar panels be installed on a library or educational institution?: Yes, solar panels can be installed on a library or educational institution. In fact, installing solar panels on such buildings is a great way to promote renewable energy and reduce carbon emissions. It not only helps to lower electricity bills but also serves as an educational tool, teaching students and visitors about the benefits of solar power and sustainable living.

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.

Q:i have a 2v 2a solar panel that i want to use to charge a 2v battery .Have found out that i need a charge controller so i don't over charge the battery.I have found a cheep one its 2v but 7a will it still work ?All-so im planing on running a 2v water pump off the battery with a timer,its for watering my garden.Will the timer have to be 2v as well ?any help on this would be greatly appreciated thanks .: The charger will accept whatever current is necessary from the solar panel up to 7A. It's not like the solar panel will force 2amps into the charger/battery -- the charger will control the current going to the battery. I question whether or not the 2V panel will actually charge the battery, though, because in order to charge a standard lead-acid 2V battery you need to have about 4.5 volts applied to the terminals. Perhaps the charger has a boost circuit -- I don't know without looking at it or knowing the brand/model number, etc. The timer must be 2VDC, but, if you only have a timer that is rated for 20VAC, you can buy a small inverter that will take 2V and supply the necessary 20VAC. An inverter rated for 20 to 50 Watts should be sufficient. These usually cost under US$25. .

Q:I mean like bread is made of wheat, what are solar panels made up of?How are they manufactured?: Solar panels (aka photovoltaic panel) are most often made up of thin wafers of crystalline silicon or cadmium telluride. As photons from the sun enter the photovoltaic cell, electrons are freed from the substrate when are then collected by wires that run throughout the panel. And as we know electrons=electricity!

Q:Can solar panels be installed on agricultural or farming operations?: Yes, solar panels can be installed on agricultural or farming operations. In fact, many farmers and agricultural businesses are increasingly adopting solar energy as a sustainable and cost-effective solution to power their operations. Solar panels can be mounted on rooftops, open land, or even on barns and sheds, providing clean and renewable energy to offset electricity costs and reduce carbon emissions. Additionally, solar panels can help farmers take advantage of unused or underutilized land, providing dual benefits of energy generation and agricultural productivity.

Q:Can solar panels be used in areas with high humidity or saltwater exposure?: Yes, solar panels can be used in areas with high humidity or saltwater exposure. However, the performance and longevity of the panels may be affected by these environmental factors. It is important to choose solar panels specifically designed for such conditions and regularly maintain and clean them to ensure optimal efficiency.

Q:how much would you pay for a 2'x4' solar panel that puts out 24 volts and 74 watts?: It all depends on where you live and who you get them installed by.
