Q: Can solar panels be installed on an RV or camper?: Yes, solar panels can be installed on an RV or camper. They provide a convenient and eco-friendly way to generate electricity while on the road.

Q: If a solar panel is a .5kW system, what length of time is it putting out that much power? Every hour?: Power = work done/time taken In other words, Watts=Joules/second. In this respect, power is a little like speed (m/s). Your question is looking at a car with a 50mph top speed, and asking how long is it going that fast? The solar panel will produce .5KW for as long as you require it. Enough to boil a kettle, run a modest electric heater etc,

Q: Can solar panels be installed on swimming pools?: Yes, solar panels can be installed on swimming pools. These panels can help heat the pool water using solar energy, reducing the need for traditional heating methods and lowering energy costs.

Q: i don't know very much about it, but can you somehow take off the little solar panels off of the outdoor light things and make it so you can hook an outlet up to it and plug in to it like a phone charger for electricity.: Little solar panels on lights are very low power. The battery in one such may be 0.5 Amp-hours and .2 V ; it may be different but it should be marked on the panel/battery/manual. An outlet in your house is designed to run on 20 V (typically in N. Am.) and they run on alternating current (AC) whereas the panel generates direct current (DC). (If you don't know the difference, do not worry to much but just understand that they are not directly compatible.) You therefore need an inverter to change DC to AC (and lose some although inverters are now very efficient). But the amount of power generated by those panels is still very small. That is why solar lights are low power (just a few watts in most cases). To make things even more irritating, phone chargers do not work off 20 V AC as you are charging the battery and need a low voltage DC -- which is what the solar panel is giving you. It is almost certain that the voltage from the panel will be less than the voltage required for the phone. The charger is mostly cable but there is a black box incorporated and it should say what the voltage and current output are (the input will be 20V). So you should be able to overcome this not by hooking up the panel to a 20V outlet and then plugging the charger in but by hooking up the panel to the phone directly if you can get enough voltage out of the solar panel (or hook up several) and if you fashion a connection device. They already make them -- solar battery chargers and I am sure you can enter that into a search engine and find loads. Typically the panel alone is much more than a solar light -- which shows the relative power requirements.

Q: Can solar panels be used in commercial buildings or industrial settings?: Yes, solar panels can be used in commercial buildings or industrial settings. In fact, they are increasingly being incorporated into such environments to offset energy costs, reduce carbon footprint, and promote sustainability. Solar panels can be installed on rooftops, parking lots, or even as part of building facades to generate clean electricity that can power various operations in commercial or industrial facilities.

Q: So I want to go completely solar. Do I need the connected solar panels alone for after sundown hours; Do I need something else in order to have energy to run my entire house throughout the night?In other words do solar panels store the energy for after sun-down or do I need other devices to store the energy?: solar panels don't store energy, they only generate it. If you want to store energy you need a battery bank of some kind to get you through the night and anytime the sun isn't shining. If you have a little extra in the budget you might look at a geothermal system for your home's heating and cooling needs. They're highly efficient systems and you can supplement however you like. Whatever you do, though I hope you have a good building envelope in place already. Solar panels are cool, but if you have a leaky house, you're still not getting the best out of your panels. Do the more mundane stuff first. Insulation, windows, and weather-tight doors.

Q: The colder a solar panel gets the more efficient it seems to be. As the panel warms, it loses some efficiency. Why is this so? Please explain in a way you would expect a high school kid to understand it, as I am a high-schooler and i have to explain this to other high-schoolers.: All PV Solar Panels are affected by heat. The hotter the solar panel, the lower the power output - but how significant is the effect. I decided to test one of our small 6V 250mA Solar Panels to find out. Solar Panel next to halogen lamp with temperature probe. Reproducing the kind of temperatures solar panels experience in hot climates is not easy on a cloudy May day in the UK, so a 50 Watt halogen office lamp was used at a distance of 55mm from the solar panel as a sun substitute. This guaranteed a constant level of light would be incident upon the solar panel ensuring the quality of the results collected.

Q: Heard you can put solar panels on laptops Anyone know if it can work on a Dell mini 0v? I've seen he USB slot solar pana but can someone tell me where to gt these?: That strikes me as completely impractical for most circumstances. The power output of your mains adapter is 30W and to do that you are looking at at least five or six square feet of solar panels costing in the region of $600 even from a surplus supplier I know. You could do it cheaper (maybe $50 on panels) but then you would be looking a more primitive panels and need perhaps thirty square feet of solar panels. This is a completely different exercise to creating a solar powered USB charger - the power requirement is a lot higher. Astronomy and space?

Q: What is the impact of roof shading on solar panels' efficiency?: Roof shading has a significant impact on the efficiency of solar panels. When the panels are shaded, they receive less sunlight, which reduces their ability to generate electricity. Even a small amount of shading, like from nearby trees or buildings, can lead to a drop in overall panel efficiency. It is crucial to ensure the panels are installed in areas with minimal shading to maximize their performance and yield.

Q: How do solar panels affect the property's carbon footprint?: Solar panels can significantly reduce a property's carbon footprint by generating clean and renewable energy from the sun. Since solar panels produce electricity without emitting harmful greenhouse gases, they help to offset the carbon emissions associated with traditional energy sources. By using solar energy, properties can reduce their reliance on fossil fuels and make a positive impact on the environment by reducing their carbon footprint.
