Q:What are the benefits of using solar panels?
There are several benefits of using solar panels. Firstly, solar panels generate renewable and clean energy by harnessing the power of the sun, reducing our dependence on fossil fuels and reducing greenhouse gas emissions. Additionally, solar panels can help to save money on electricity bills, as they generate free electricity once installed. They also require minimal maintenance and have a long lifespan, providing a reliable source of energy for years to come. Moreover, solar panels can increase the value of a property and contribute to energy independence, especially in remote or off-grid areas. Overall, the use of solar panels promotes sustainability, cost savings, and a cleaner environment.
Q:I don't see much solar panels on people's houses where I live. I got a long time to go before doing so but I was planning on buying a few solar panels when I retire in the far future. In your opinion, is such an investment worth it? Would you buy them? I realize they are very expensive hence why I said when I retire. Thanks for your opinion
Solar power is still an expensive way to purchase power, as of 2007, it was 38 cents per kwh while the cost of power from coal is 0.6 cents per kwh. Of course regulations have prevented new coal power stations from being built so it's really natural gas power stations at 5 cents a kwh that solar has to compete with. Solar is dropping in price but the best you can hope for is for it to reach parity with natural gas someday soon and it hasn't yet. The other issue is that you pay up front for solar power which as any economist will tell you is even more expensive and involves greater risks. However, as part of a strategy to become as self reliant as possible when you retire and have a fixed income, it's a reasonable prospect, not only will the technology become less expensive by then but at that point, fixing the price of the energy costs is more valuable than the cost of the energy. Focusing on personal finance and learning how to invest which very few people know how to do is more important right now. When you retire, hopefully you can afford to build a passive solar home with photovoltaic solar panels and wind turbines but still on the grid for efficient net metering and with a greenhouse where you can grow the staples that you need and perhaps even some biodiesel for your google driven car. Having a reasonable portfolio is really the only way to achieve that goal.
Q:i have this usb solar panel charger i am building and the solar panel is about 2by .5quot;, so i was wondering if a led light can power it, if so will one be good or would i need more? if so how many?
While I understand Search's answer, because it was also my first reaction, am I wrong in thinking that this is some sort of science fair project, for which you need to power a solar panel indoors as though it were being illuminated by the Sun? The question at least makes sense in that context. Solar panels provide modest power even from room lighting, sometimes calculators are powered by small panels, but that is a tiny amount of current. . You'll probably do better by asking this question (a bit more clearly) over in Engineering. It's not really an Astronomy Space question, though there may be some crossover between the two groups of users. Meanwhile, while some white LEDs can be pretty dazzling to the eye, I don't know how much actual power they are pulling down compared to what you'll need the panel to generate, but I don't see why it shouldn't work. I just don't know how many LEDs you would need. . .
Q:I'm from Toledo, OH about 2 miles from the MI line. We are a foster family and have adopted 5 children. We just moved into a 5400+sq 2 story home. We have (3) 2.5-3 ton AC units to cool this huge house. We got the house cheap...$75k couldn't pass it up! Anyway...I was wondering how many solar panels it would take and of what wattage to power these Central Air Units and maybe the rest of the house. We have 3 people in our home......9 of which are children who leave the lights on and run hot water to beat the band. We have all brand new energy star appliances and front loader washer and dryer. Gas Range and Gas hot water tank. Was thinking of using metal window frames and buying solar cells and making my own panels. Just don't know how much to buy. We face south with no trees. Constant Sun. thanks for your help. An e-mail address to bounce questions off of would be helpful if you experienced. tx.
Yes and no. solar panels are expensive and inefficient. therefore the power you generate will cost many times what the same power from a power plant would, and therefore you generally can only run a few low powered things at once. Secondly they don't generate electricity at night so you need some means of storing the power. tht means even more efficiency losses. They also only generate DC power, so you have to run the power through an inverter to make 0V AC. inverters are notoriously inefficient and expensive as well, so now you've thrown even more power away converting it. Bottom line, you're gonna pay far more than $600 a month for these things and you won't get nearly the amount of power you think. it is generally a waste of money to do this in almost all cases. The ROI is usually well over 20 years before you break even.
Q:Do solar panels require regular maintenance?
Yes, solar panels generally require regular maintenance to ensure optimal performance and longevity. This includes periodic cleaning to remove dirt, debris, and snow, as well as checking for any possible damage or malfunctioning components. Additionally, regular inspections and maintenance by professionals are recommended to identify and address any potential issues or inefficiencies.
Q:What is the impact of roof orientation on solar panels' performance?
The impact of roof orientation on solar panels' performance is significant. The orientation of the roof determines the amount of sunlight the panels receive throughout the day. Ideally, solar panels should be installed on a south-facing roof to maximize their exposure to sunlight. East and west-facing roofs can also work, but they may produce slightly less energy. North-facing roofs are generally not suitable for solar panel installation as they receive the least amount of sunlight. Overall, roof orientation plays a crucial role in determining the efficiency and effectiveness of solar panels.
Q:I'm making a model of a solar photovoltaic tower for a school project. I need a way to store energy, and we thought about using capacitors (mainly because of our somewhat limited funding). The tower will have a small photovoltaic panel (around the size of a laptop keyboard with number pad) and some (around 50) quot;heliostats(just the mirrors, no moving parts). What kind of capacitors should i use? and would a capacitor bank be better? i am getting confused with all those uF, pF and can't see the difference.Thanx in advance

Q:Can solar panels be used in off-grid systems?
Yes, solar panels can be used in off-grid systems. Off-grid systems are designed to operate independently from the electrical grid, and solar panels can generate electricity from sunlight, making them a reliable and sustainable source of power for off-grid applications.
Q:How much space is required for installing solar panels?
The amount of space required for installing solar panels depends on various factors such as the type and size of the panels, the energy needs of the property, and the efficiency of the panels. Generally, for residential installations, it is recommended to have around 100-400 square feet of roof space per kilowatt of solar panels. However, ground-mounted systems may require larger areas depending on the number of panels and their tilt angles. It is advisable to consult with a solar installer or expert to determine the exact space requirements for a specific project.
Q:I have an inverter and a battery 20 Amperes.Daily sun shine approx. 7 Hours.Do I need to buy anything or should I connect the solar panel to the Battery direct?
connect the solar panel to the Battery direct during the day time that's how it works in ALL situations !
