Q:Can solar panels be installed on desalination plants?: Yes, solar panels can be installed on desalination plants.

Q:There are places in the US where it is sunny almost all the time, like the southwest. But if we covered an area of the Sahara with solar panels, the sun exposure with the area would generate enough energy for the whole US at least. Plus, I would imagine it would be a great source of income for those countries.Why isn't this a topic under discussion or even mentioned between countries' governments/in Congress/in politicians' viewpoints?: Good question. One of the reasons is the greed of manufacturing companies. No matter the profit margin of the product, they seem to want to charge so high a price that the break even point is ten years down the road, so the true savings are few. The cost of solar panels should have dropped way lower than they have by now. I believe that the political correctness of the product will tempt the manufacturers to keep the prices artificially high. One other answerer is right, the panels are very fragile, and damage would destroy the investment, so new inroads need to occur in technology to protect the panels from damage. Somewhere in the middle is a profit for the manufacturers, and savings for the consumer. I hope we find that middle-ground soon.

Q:If a solar panel has a power rate of 80 Watts and efficiency of lets say 30%. Does that mean the maximum power this solar panel can generate is (30/00)*80=54 Watts or its just 80 Watts?: If it says STC or Standard Test Conditions on the nameplate or documentation, then that means 80 watts under bright sun at an unrealistically cool temperature. It is rare to see that power in real life, except when the perfect storm of conditions come together. There is also a PTC rating for some panels, which is more realistic. If the panel does not say STC or PTC, the manufacturer is free to make up whatever test they feel like, which generally leads to ridiculously overstated power. As for efficiency, for residential panels, that's generally only of academic interest. A 80-watt panel is 80 watts, regardless of the efficiency. A more efficient panel will take up slightly less space, but most people are more interested in the total price, since roof space is generally not an issue.

Q:I am completely ignorant on this subject. I was just wondering out of curiosity of how many solar panels and equipment that it would take to run a central ac for a 2500 sq ft home and a pump for a medium sized pool. I'm talking running ac for like 8 hours a day to keep around 65-70 degrees and running the pump 24/7. Just looking for a general ballpark answer.: Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.

Q:Do I need some type of regulator when the batteries are fully charged.?? The Arco Panels voltage is approx 7VDC at 2.5 amps, Should I limited the voltage to 4VDC???. I would like to connect both panels to up to five batteries at one time...???: You can buy Solar Charger Regulators. I don't. These chargers limit the charging current to the batteries, so you do not get a full efficiency of the solar panel. They disconnect the batteries from the user side (the bulbs you use) if the battery voltage goes below a certain level (i.e. below 8V for a 2V battery), so you cannot use all the power available in the batteries, even in emergency. They introduce, at least, a 0.7V loss (diode forward voltage) between the panel and the battery. If you have SEVERAL panels and a lot of batteries, use a controller as above. If you only have one panel, insert a 5A trip fuse in line (in your case: twice the current of the panel), and a 0-20A diode in series between the panel and the batteries (Kathode side of the + of the battery, Anode side of the + of the panel). Install a voltmeter across the battery. The fuse will prevent any short or over-charge current. The diode will prevent the battery to discharge into the panel at night if it is not already protected. The voltmeter will allow you to watch the status. Your thought of limiting the voltage is useless: should the battery be low, the panel will drop its voltage, limited by the max current. Should the battery be fully charged and the solar panel at full efficiency, it will just try to charge the battery more. A bit of bubbles may result, hence the voltmeter to watch over it. If you want to limit the voltage to 4V, put a 4V Zener (4Vx2.5W!) in series with a resistor of, say, 7V-4V/2.5A or ~ Ohm, 5W, in parallel with the panel.

Q:Can solar panels be installed on disaster relief shelters?: Yes, solar panels can be installed on disaster relief shelters. Solar panels provide a sustainable source of energy and can help power essential equipment and devices in these shelters, such as lights, communication systems, and medical equipment. This reduces the dependency on traditional energy sources and ensures uninterrupted power supply in critical situations. Additionally, solar panels are lightweight and portable, making them suitable for temporary shelters and easy to transport to affected areas.

Q:Can solar panels be installed in areas with high winds?: Yes, solar panels can be installed in areas with high winds. However, it is crucial to consider the design, installation, and maintenance of the solar panel system to ensure its durability and stability in such conditions. Reinforcements and proper anchoring techniques can be employed to withstand the wind load and prevent any damage to the panels.

Q:Can solar panels be installed on vehicles?: Yes, solar panels can be installed on vehicles. They are commonly used on electric cars, boats, and recreational vehicles to harness solar energy and help charge their batteries.

Q:Can solar panels be installed in areas with high seismic activity?: Yes, solar panels can be installed in areas with high seismic activity. However, extra precautions need to be taken during the installation process to ensure their stability and resistance to earthquakes. Specialized mounting systems, such as those with adjustable foundation designs or seismic restraints, can be utilized to secure the panels in such areas. Additionally, it is crucial to comply with local building codes and regulations to ensure the panels are installed safely and can withstand seismic events.

Q:How Much energy does Solar Panel Produce,and How long can Solar Panels go without maintenance.: Solar panels come in many kinds, using a variety of technologies and sizes, but the most common is still the crystalline silicon type. The power produced is variable, but the better ones you can buy approach 20% efficiency, and the peak energy from the sun is 200W/m^2 (Watts per square meter). This only occurs when the panel is lined up with the sun on a clear day with the sun high in the sky. The efficiency is also affected by how the electrical energy is taken from the panel, and the temperature of the panel. In the full sun the temperature approaches 60C, so the voltage drops. The links below provide a lot of information about such matters. A BP panel 50mm x 674mm gives a peak power of 20W. This is .07 square meters. As you can see this is very close to 20%. (The third link). However this is less in practice because the sun may not be full sun and may not be perpendicular to the panel. The output drops as the cosine of the angle to the sun, more or less. Even with peak sun this would produce only about 00W charging a 2V battery directly, unless an electronic Maximum Power Point Tracking (MPPT) charge control is used.
