Q:Can solar panels be installed on public parks or gardens?
Yes, solar panels can be installed on public parks or gardens. Many cities and municipalities are increasingly adopting solar energy as a sustainable and renewable power source. Installing solar panels in public parks or gardens can help generate clean energy and contribute to reducing carbon emissions. It is a practical and efficient way to utilize open spaces while also providing environmental benefits.
Q:Are photovoltaic cells the same as solar panels?
All okorder
Q:Home depot has solar panels but they are so expensive? were is the best place to get them?
Technology okorder Good luck!
Q:Can solar panels be used for heating swimming pools?
Yes, solar panels can be used for heating swimming pools. Solar thermal panels, specifically designed for pool heating, capture the sun's energy and transfer it to the pool water, increasing its temperature. This renewable and eco-friendly method is a popular choice for pool owners looking to save on energy costs and reduce their carbon footprint.
Q:If this was sold back to the grids what would be the profit i would stand to make per day on energy received in these panels? How did you come up with this answer?
Considering capital outlays, such a system might never recover its initial investment. That's why we don't see such small photovoltaic plants popping up around the country - the economic case isn't there. One of the problems is that you would have to sell your electricity wholesale, at a ridiculously low price like 2 cents / kWh. If you were displacing electricity that you would otherwise use, then the financial case is different. Retail electricity could be 20 cents / kWh, 0 times as much, and you could get your money back over time, and start to make a profit. I've assumed you're in the US, with no special feed-in tarrifs. If you're in a country with a premium rate for solar-generated electricity, the business case could be very different.
Q:If my school was to purchase enough solar panels to run the school off only their power, how much might that cost? (I have a really small school, only 384 kids.)Just general prices of solar panels and how much electricity they yield would be fine too.
I don't know the square of your school. generally the solar panel is 0.6$ per watt. so if 5kilowatt can meet your demand the cost will be3000$.
Q:Can solar panels be installed on a building with historical significance?
Yes, solar panels can be installed on a building with historical significance. However, it is important to consider the preservation of the building's architectural integrity. Careful planning and design are necessary to ensure that the installation of solar panels does not compromise the historical value of the building.
Q:Can solar panels be installed on water treatment plants or utilities?
Yes, solar panels can be installed on water treatment plants or utilities. In fact, many water treatment plants and utilities are increasingly adopting solar power as a sustainable and cost-effective energy solution. Solar panels can be installed on rooftops, open fields, or even on floating platforms over water bodies, providing clean energy to power the operations of these facilities.
Q:The first solar panel that creates energy from UV rays... who created it
The first photovoltaic cell was developed at Bell Labs in 954. The team included G.L. Pearson, C.S. Fuller, and D.M. Chapin. A panel is composed of many cells. They respond to a wide range of wavelengths, not just UV.
Q:ok so when a solar panel is marked as a certain wattage dose that mean it makes that much in a day in an hour or constant, dose it still work at night or what ? is it worth it or is it more of a pain? can some one tell me what all the watts and volts mean ?? and can some one tell me what a kilowhat is in refrence to some thing i understand like howmany loads of laundey can you do wt a watt? i need help understanding this stuff?
Caykay, Your question is amazingly great and obscure so that's perplexing to respond to. photograph voltaic panels are designed to value DC batteries, so which you will would desire to alter your electric powered gadget to paintings with DC. So, your quesiton isn't that straightforward to respond to. you will desire to start on your very own examine to get to a useable prognosis / answer. you will desire to renowned what a watt is and an amp is. you will desire to renowned what the cost of a kilowatt is to confirm what proportion watts you utilize in a 300 and sixty 5 days. then you certainly can start to estimate what proportion photograph voltaic panels you want. you do no longer throw away photograph voltaic panels. this is the component of them. as quickly as bought, the capability supplied for years is considered 'loose'. the place you reside has alot to do with it too. Sunny Arizona, or Florida are great and could require fewer panels than different, extra cloudy places. expenditures and structures are complicated, yet obtainable to be researched on the information superhighway. you could touch broking / distributors and that they're going to clarify it ot you. superb to you.
