Q:Can solar panels be used to power electric vehicles?
Yes, solar panels can be used to power electric vehicles. Solar panels can convert sunlight into electricity, which can then be stored in a battery and used to power an electric vehicle. This helps reduce dependence on fossil fuels and promotes sustainable transportation.
Q:I know absolutely nothing about electronics but have a lot of money. I am thinking of buying the Sunforce 3730 30W monocrystalline solar panel (the best I could find that was that size or smaller). What would be a good battery to go with it? I am thinking of buying a 2V Concorde Sun Xtender (again, the best I could find). But how many batteries will I need? I want enough batteries that it would take the solar panel 2 days to completely charge them from empty (bearing in mind the unavoidable inefficiencies like cloudiness/changing sun angles). Also, what other stuff would I need, like I hear something about a quot;charge controllerquot;? Any suggestions would be appreciated.
If you are at a location/time where the panel will put out less power, you can adjust the battery size accordingly. And running a battery to empty is very bad for it's service life, so it's better to go a bit bigger.
Q:How much space do solar panels require?
The amount of space required for solar panels can vary depending on factors such as the type and size of the panels, their efficiency, and the energy needs of the system. On average, an average-sized residential solar panel system typically requires around 100-400 square feet of roof space. However, ground-mounted systems can require larger areas, and more efficient panels can generate the same amount of electricity in a smaller space.
Q:Can solar panels be installed on carports or other structures?
Yes, solar panels can be installed on carports or other structures. In fact, carports are a popular choice for solar panel installations as they provide an ideal location for capturing sunlight and also offer additional benefits such as shading for parked vehicles and protection from the elements. Installing solar panels on other structures like roofs or pergolas is also feasible, depending on the structural integrity and suitability of the location for harnessing solar energy.
Q:How do solar panels impact the electrical grid?
Solar panels can have a positive impact on the electrical grid by generating clean and renewable energy. When connected to the grid, they can contribute to reducing the overall demand for electricity, especially during peak times. However, their intermittent nature and fluctuating output require grid operators to carefully manage the variability to ensure grid stability. Additionally, solar panels can decentralize power generation, leading to a more resilient grid and potentially reducing transmission losses.
Q:Can solar panels be installed in a shaded area?
Solar panels can be installed in shaded areas, but their efficiency and power output may be significantly reduced. Direct sunlight is necessary for optimal performance, so shaded areas may not provide the same energy generation as panels in direct sunlight.
Q:Can solar panels power my entire home?
Yes, solar panels have the potential to power your entire home, depending on various factors such as the size of your solar panel system, the amount of sunlight in your area, your energy consumption patterns, and the efficiency of your appliances. It is important to consult with a solar professional to assess your specific energy needs and design a system that can meet your requirements.
Q:We have LED at the output of 40 watts and is used for 0 hours giving us 400 Watts-hr of energy consumed.Rechargable batteries needed are 2 V. 400/2 gives us 34 Ampere-hour battery needed. If we want it for 3 days, It would be 34x3=00 Ah. So the battery needed 00 AhNow how do I select the solar panel which can charge this/these batteries? What should be its rating?
First, you need to make sure that your battery can take a regular 34Ah discharge without damage. The usual wisdom when using deep cycle lead-acid batteries is to allow for no greater than 50% discharge. This is to prevent the battery from ageing prematurely. Note that automotive batteries are not usually considered suitable for deep-cycle applications. Best allow for at least 200Ah capacity. Your solar panel capacity needs to take into account that whatever the nameplate output of the panel, that will be what it will produce under ideal conditions, actual output will always be less, often quite a bit less. You also need to allow capacity to cope with dull, overcast days when the light level is very low. You can get solar maps that will give you the sunshine hours and irradiation levels at your location. The solar panel capacity ends up being a juggling act between available funds/space and how critical it is that the light always works as desired. Let's say you had a 400W panel, which sounds quite generous. In the middle of winter, it may produce only 75W for 5 hours on a dull day, not quite enough to run the light for 0 hours. Would you expect several such days in a row? How many days could a 00Ah of battery capacity cover under these conditions?
Q:What is the most affordable, yet highest watt solar panels available?
Those two requests are somewhat at odds with each other. Trina and Suntech make panels that are generally good value. You can search the web and find your best price. If this is for something that does not need to last long, you could get amorphous panels and save some money. But they will degrade quickly in a few months, then slowly over a few years.
Q:i have a 50 watt 2 Volt solar panel..Will it can switch on directly a car head light on a sunny day??? How much head lights it can support on a bright sunny day??? if its cloudy then can it run a single Head light???? i have no batteries just want to connect a car Head light directly to solar panel.
It should illuminate two auto headlights on a sunny day, if it really generates 50 watts at 2 V. On a cloudy day, I don't know. It depends on how cloudy it is.
