Q: Which of these units determines how much electric energy a solar panel can generate?
Light is power in the form of electromagnetic radiation from the sun. We receive about 000 watts per square meter on a sunny day. The solar panels do convert that sunlight into electrical power at a little less than 25% efficiency. Light intensity and power per square meter (W/m^2) are closely related. The more intensity, the more watts per square meter. So the answer is : Yes, from light intensity which directly proportional to watts per square meter
Q: If my school uses 88240kWh of electricity per month and I have 000 50W solar panels running for 6 hours a day, does it mean it will take 88240kWh / {{[(50W x 3600s)*000]/000}kWh x 6} number of hours to generate that much electricity (88240kWh)?
running six hours a day doesn't mean much. You need to look at the solar insulation charts for your school's geographical location to come up with a better factor. The easiest number for you to use is sun hours. For example, Washington DC averages 4.23 hours. Do a Yahoo search for sun hours and you should find lots of charts. Solar panels rated at 50W give this output at full sun near noon at full brightness (no clouds). The sun hour factor makes it easy to find the equivalent number of full brightness hours. So, using Washington DC as an example you have: 000 panels * 50W * 4.23 sunhours/day = 634kWh a day on average. You state your school uses 88240kWh/month which is 6274kWh a day. This would mean you need ten times more solar panels since there is no way to get more daylight. Be careful to put in all the units in your formula and cancel them out to make sure you don't end up with a nonsense result. The title of the question would be answered as followed: 50W/000 * 4.23 sunhours/day = 0.63kWh/day or 9kWh per month or 228kWh a year. These are annual averages. If you wanted a specific month, you would need the sun hours for that month. Hope this helps.
Q: Can solar panels be used in areas with high winds?
Yes, solar panels can be used in areas with high winds. However, it is important to ensure that the solar panel installations are properly designed and anchored to withstand the wind speeds typical for the area. Additionally, selecting durable and wind-resistant panel models can help mitigate any potential damage caused by strong winds.
Q: How much space is needed to install solar panels?
The amount of space needed to install solar panels varies depending on the size and quantity of panels being installed. On average, a single solar panel requires about 15-20 square feet of space. However, it's important to consider factors like panel orientation, shading, and energy requirements to determine the exact space needed for an installation.
Q: Can solar panels be installed on disaster relief shelters?
Yes, solar panels can be installed on disaster relief shelters. They provide a reliable and sustainable source of energy, allowing these shelters to have electricity for lighting, charging devices, and powering essential equipment, even in remote or disaster-stricken areas. Solar panels can greatly enhance the functionality and efficiency of disaster relief shelters, contributing to the overall effectiveness of relief efforts.
Q: Are there any fire hazards associated with solar panels?
Yes, there are potential fire hazards associated with solar panels. Although solar panels themselves do not typically catch fire, electrical malfunctions or faults in the wiring, inverters, or connectors can lead to overheating and fire. Additionally, if a fire breaks out in the surrounding area, solar panels can hinder firefighting efforts by creating potential electrical hazards and obstructing access to the roof. Therefore, proper installation, regular maintenance, and compliance with fire safety regulations are crucial in mitigating these risks and ensuring the safe operation of solar panel systems.
Q: It measured volts before I attached it, and after attaching the voltage regulator device, the voltage dropped down to 3 volts, even when just measuring the difference in the solar panels nodes themselves, suggesting that the entire panels voltage dropped and not just the voltage in the regulator. I tried testing it with a power supply of 7 V 0. A and it works fine, but I don't know why it won't work for the solar panel.
you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
Q: I'm thinking of getting a solar panel for my house to help cut back on power use (I live in New Mexico). What sort of appliances can I run on a watt solar panel? Is it worth it to get a single watt panel or is it more efficient to get a multi-watt panel?
watt is a very small amount of electricity. The typical household uses several million watt hours per year. watt would be enough to trickle charge a battery to run an LED nightlight. I believe the little self contained walk lights that I have put out have a 0.35 watt Ni-Cad battery. That could be recharged by a watt solar panel.
Q: What's your opinion on solar power? More specifically, having panels installed on your roof to reduce your electric bill. I'm having a consultation tomorrow to get more details. I live in the SW, so it's always crazy sunny here. I don't know what the cost will be yet. Is it something you'd consider if the situation was right? If not, why?
Just had them installed on a development of 4 homes and they look goood! So far each user has free electricity during daytime for 3/4 of the year. If you live in a hot country - that's free A/C to keep you cool. The downside is that it is grid-tied so there is no storage, which means that if you use electricity to cook the evening meal - you don't get that free. What we advise to do instead is to make use of slow cookers that cook meals during the day - for FREE, and just serve it up in the evening as it keeps the heat. It would be more effective if you used storage radiators and heated hot water tanks for washing/bathing using it but this hasn't been added yet. It's free power all day - so what is there to complain about? The only catch I have found is that some power companies charge YOU if you export power to the grid - so just watch out for that, and design your system to avoid this if this applies, but most just don't pay anything - so you may as well use what you get.
Q: Its cloudy out and i have a solar panel that has 3, .5 volt cells But how do i charge it without sun any other ways?
Haven't you watched the Truman Show? Just cue the sun...
