Q: I have noticed how solar panels cause a glare. Since I am not around solar panels all the time I relate it to when the sun reflects off another car and right into my eyes. So I always wonder if solar panels effect birds and/or animals due to the glare. If I am wrong and solar panels aren't this bad please tell me.
No, they don't solar panels are harm less to the enviroment. They take in light energy, nothing else. So you don't have to worry about injury!
Q: If I wanted to add solar panels to my home to produce on average, 8 kWh of electricity daily, how much do you estimate it would cost using state of the art technology?I live in Virginia (Washington DC Metro Area), and I have Dominion Power. I pay the following electric rates:Jun-Sep $0.0904/kWhOct-May $0.0776/kWhAnnual Ave: $0.0824/kWhDistribution charges add on approximately another $0.0228/kWh.How long would the ROI for an 8 kWh/day solar system be?
Figure 8 hours of sun per day, so 8 kW-hr is a rate of kW, which is a medium sized panel, probably not enough to operate your house totally, unless you have a very small unit. Averaged over 24 hours, that is power at a rate of only 300 watts, enough for a TV. Average US home use is .2 kW, which over 24 hours is 29 kW-hr, plus you need extra for cloudy days, peak demands, and to charge batteries. You have to decide off-grid or on-grid, and if you want to (and are allowed to) sell excess power to the power company. Off gird, the cost of batteries and charge controller are a large part of the cost. On-grid, you have to purchase equipment approved by the power company to match your power with the grid. Panels will cost about $3 per watt, so for 000 watts that is $3000. Double that for installation, then add in cost of charge controller, inverter, batteries, etc. The last items depend on your alternatives, see paragraph above. .
Q: How much space do solar panels require?
The space required for solar panels depends on several factors such as the power output of the panels and the efficiency of the solar cells. On average, a typical solar panel requires around 10-20 square feet of space. However, it is important to note that solar panels can be mounted on rooftops, installed in large solar farms, or even integrated into building materials, allowing for flexibility in their placement and utilization of available space.
Q: Can solar panels be used for powering security systems?
Yes, solar panels can be used to power security systems. Solar panels convert sunlight into electricity, which can be used to power various devices, including security cameras, alarms, and sensors. This allows security systems to operate independently of the electrical grid, making them more reliable and cost-effective in remote locations or areas prone to power outages. Moreover, solar-powered security systems are also environmentally friendly, reducing reliance on fossil fuels and minimizing carbon emissions.
Q: Can solar panels be used to power a train?
Yes, solar panels can be used to power a train. Solar panels convert sunlight into electricity, which can then be used to power various applications including trains. Solar-powered trains have been successfully implemented in some parts of the world, showcasing the feasibility and environmental benefits of this renewable energy source.
Q: How much would it cost (approximately) to convert my home (3 bed. 2 bath) to a green home that is run entirely upon solar panels on my roof? From the panels through installation does anyone know a price break down?
Either you, or someone else, asked this same question yesterday, and the answers given were that it is not possible for us to answer it. The costs depend on where your home is located, what prevailing local labor rates are, how difficult it is to get the equipment to the site, etc, etc. I think one of the answers was that for a 3 bedroom, 2 bath house the cost for all the necessary equipment listed would be in the neighborhood of 20 to 30 THOUSAND DOLLARS. I think that was an underestimate, and that it could be 40 to 50 THOUSAND!!!!! The answerer also pointed out that due to the exorbitantly high costs of the technical equipment that at this time the equipment will wear out BEFORE IT EVER CAN PAY FOR ITSELF IN SAVINGS for on the grid electricity. I agree with that. You need to discuss your wants with 3 or 4, even 5 or 6 LOCAL ELECTRICAL CONTRACTORS to get a reasonably accurate estimate of the costs!!!!!!
Q: How can I calculate the amount of watts needed for a solar panel to power a water and air pump in gal/hr and a 600 watt LED light?
With you up to solar panel, then things go downhill. Your Water pump will be rated at gal/hr but how about the air pump? 600watt LED? What you need to know in order to select your solar panel is how much current you will be draining. You can work this out if you know how much power and how long they need to run. Please, a bit more information (that is relevant!).
Q: Can solar panels be used for powering a wastewater treatment plant?
Yes, solar panels can be used for powering a wastewater treatment plant. Solar energy can be harnessed and converted into electricity, which can then be used to power the various components and processes involved in wastewater treatment. This renewable energy source helps reduce reliance on non-renewable fuels, lowers operational costs, and minimizes the environmental impact of the treatment plant.
Q: In nature, green leaves collect light and produce energy. Is this what they copied to make solar panels? If not how hard would it be to make artificial leaves that would power our homes?
Not at all. Good guess but they are completely different processes. Solar panels use chemicals that create electricity when exposed to light. Photons pretty much add energy to the atoms and affect the electrons creating electricity. Feel free to look up how solar cells work online.
Q: Can solar panels be installed on a high-rise building?
Yes, solar panels can be installed on a high-rise building. In fact, high-rise buildings can be ideal locations for solar panel installation due to their height and large surface areas. By utilizing the available roof space, high-rise buildings can generate significant amounts of solar energy, helping to reduce their reliance on traditional energy sources and lowering their carbon footprint.
