Q:i hav e a project for school we need to calculate cost to buy and install solar panels in our school

Photovoltaic panels have almost zero recurring operating cost. Once installed, they are good for the next 20-25 years, typically. The exceptions are if the panels are not tilted, then you need to pay someone a few times a year to go up there with a mop to clean them. Otherwise, rain and morning dew make the dirt slide off automatically. The cost for your system will depend on the power needs of your school. It also depends on your location. As a government entity, a school is not eligible for the current 30% federal incentive, but may be for state incentives, depending on where you live. Anyway, once you size your system, which will be large, figure on $7 / watt cost for a large system. This would be less if you live in a state with good incentives. So for example, if you needed a 00 kW system, the price would be $700,000. $00,000 of that money is to replace the inverters that break after 5 years, so you would be paying $600,000 up front.

Q:I've run out of things to keep me entertained recently and as part of a larger project, I was curious if its possible to 'McGuyver' up a solar panel out of common materials?

Q:If you were to shine, for example, heat lamps onto the solar panel along with the sun, will the solar panel eventually not work? Or will they produce more light as long as more light is directed onto them.

yeah, as you shine light over a solar panel, it begins to lose electrons to the circuit. if you shine light with enough intensity (that means not strong light, the photoelectric effect makes no distinction between a powerful photon and a weak one, as long as they're both over a certain energy, but a lot of it, as in, a lot of photons), the material may not recover electrons at the same rate it loses it, and would stop working, until you gave it a rest.

Q:DIY, buying solar panels, room is barely 200 sq. ft. have a 5000 btu air conditioner, how many watts do I need, thinking of buying 75 watt solar panels, have space on the roof.

Yes you can.. Use it to charge a 2 volt battery then use the battery power to run a 2 volt halogen bulb. Would be much better to power some LED's with the battery -- just as much light but will last longer.

Q:Can solar panels be used for powering outdoor events or festivals?

Yes, solar panels can definitely be used to power outdoor events or festivals. They are a sustainable and reliable source of energy that can provide electricity to run lights, sound systems, food stalls, charging stations, and other equipment needed for such events. Additionally, solar panels can be easily set up in open areas, making them ideal for powering outdoor gatherings without the need for grid electricity or noisy generators.

Q:I just moved into somewhere with solar panels but don't really understand them...all I know is that they heat the water.Do I still have to turn the hot water on with the solar panels or do they heat it automatically or do they store the energy until I turn on the hot water?!

Custom solar-heating systems are unique. Does yours have a circulating pump? Does it have a storage tank? Is the fluid that goes to the panels separated from the household water and transfers heat through a heat-exchanger radiator, and the fluid has antifreeze in it? If it does, is the antifreeze of the variety that won't poison your family if there is a leak? Does your system have a thermostat-controlled pump that turns on when the water in the panels are hot? Does it have a limit-thermostat to turn off the pump when water in the storage tank is hot? There are many more variations to operation of solar-heating panels. Find out who designed it or who knows how to operate it and ask them.

Q:Can solar panels be damaged by hail or extreme weather?

Yes, solar panels can be damaged by hail or extreme weather. Hailstorms with large-sized hailstones can cause physical damage to the solar panels, such as cracks or shattered glass. Extreme weather events like strong winds, heavy snowfall, or storms can also potentially damage the panels or dislodge them from their mounts. It is important to ensure proper installation and employ protective measures, such as using hail-resistant materials or installing panels at appropriate angles, to minimize the risk of damage.

Q:Can solar panels be installed on a carport or parking lot?

Yes, solar panels can be installed on a carport or parking lot. This is known as solar carport or solar parking lot systems. They provide shade for parked vehicles while generating clean and renewable energy.

Q:I live in the UK, I have no savings (so would have to take out a loan of about ?8000), I don't know how long I plan to stay in my house, I might want to move in a year or two to take advantage of a better job so I want to keep the option open of being able to sell my house without having to pay off the cost of having the panels fitted (which I probably won't get back on the increased value they add to my house).What are the main advantages of having solar panels?What are the pitfalls the ever so eager cold callers with quotas to fill don't tell you about?Basically is it worth having them?Thankyou.

If you're talking about photovoltaic panels, for making electricity, they're very expensive. Around here I think it runs around 2 bucks a watt of capacity, just for the panels. Then they have to be installed of course, which means an electrician has to be paid, and you need an inverter also. You can also spring for a bank of deep cycle batteries if you want to be able to store the electricity from the panels to use at night or on cloudy days, but that adds another very large expense. Now if electricity is very, very expensive where you are, you could maybe pay this off in a few years, but I doubt you could pay off 8000 pounds worth of this stuff in only a couple years. If you're talking about solar for water or air heating, well, that's another deal. But those kind of setups cost a lot less to put in, I can't see anyone paying that much for it.
