Q:Can solar panels be used for outdoor lighting?: Yes, solar panels can be used for outdoor lighting. In fact, they are an efficient and eco-friendly option for providing illumination in outdoor spaces. Solar panels convert sunlight into electricity, which can be stored in batteries and used to power outdoor lights during the night. This eliminates the need for connecting to the electrical grid and reduces energy costs. Additionally, solar-powered outdoor lighting systems are easy to install and maintain, making them a popular choice for various outdoor applications.

Q:How do solar panel power systems work?: There are two kinds of solar panel power systems, one is on-grid solar power system, the other is off-grid solar power system. The on-grid solar power system: the solar panel convert sunlight into DC electric, and the DC electric is converted into AC electric by inverter, one part supply for the household load, the other supply to power grid. The off-grid solar power system: the solar panel convert sunlight into DC electric, and charge for the battery or supply for the DC load by controller, if have AC load, it need a inverter to convert DC into DC.

Q:Can solar panels be installed on a community center or recreational facility?: Yes, solar panels can definitely be installed on a community center or recreational facility. In fact, these types of public buildings are ideal candidates for solar panel installations due to their large roof spaces and high energy consumption. By harnessing solar energy, these facilities can reduce their carbon footprint, lower energy costs, and set a green example for the community.

Q:im aware i dont fully understand. but with what i do. if P = iv, and current changes with voltage, whats the point of changing either. if in any cicumstance, you end up with the same wattage, how does changing either effect a solar setup. (2v panel vs 24v)thanks in advance. explain in laymans if you can.: The choice of solar panel voltage comes down more to what the panels will be connected to. You're right that power can remain the same at the different voltages. Higher input (panel) voltages are sometimes used in inverter systems to reduce the effect of voltage draw-down. 2v panels (about 20v open circuit) work well for charging 2v batteries, connected in parallel, through a charge controller. For use of a grid-tie inverter, higher input voltages are sometimes used to reduce the effects of draw-down. You want to select and wire (parallel vs. series) your panels based on the input voltage requirement of the load, whatever it may be.

Q:Can solar panels be used in areas with high humidity?: Yes, solar panels can be used in areas with high humidity. However, high humidity levels can affect the overall efficiency of solar panels due to a decrease in their performance. The moisture in the air can cause a film of dirt or dust to accumulate on the panels, reducing their ability to absorb sunlight effectively. Regular cleaning and maintenance can help mitigate these effects and ensure optimal performance.

Q:Can solar panels be used on vehicles?: Yes, solar panels can be used on vehicles. Solar panels can be installed on vehicles such as cars, trucks, boats, and even bicycles to generate electricity from sunlight. This electricity can be used to power various components of the vehicle, such as the battery, lights, or even the motor in some cases. Solar panels on vehicles offer a sustainable and renewable energy source, reducing reliance on traditional fossil fuels and contributing to a greener and more eco-friendly transportation system.

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

Q:what is a solar panel?: A solar panel is essentially a battery charger that transforms sunlight into an electrical DC (direct current)charge.

Q:Are photovoltaic cells the same as solar panels?: Yes, they are the same thing.

Q:What is the difference between Photovoltaic Panels and Solar Panels?: Photovoltaic is a type of solar panel that produces electricity from sunlight, usually converting about 5% - 22% of the energy received from the sun into usuable energy. There are different types including those grown in a lab, silicone, and glass. Another type of solar panel is solar thermal which convert sunlight into heat. This is usually ran into some sort of system that heats water or a mixture w/ glycol in colder regions. This hot water can be used for showers, etc, or heating the home. You get much more bang for your buck with solar thermal.
