Q:Can solar panels be installed on historical or protected buildings?: Yes, solar panels can be installed on historical or protected buildings. However, there are certain considerations and guidelines that need to be followed to ensure that the installation does not compromise the architectural integrity or cultural significance of the building. Special care is taken to design and install solar panels in a way that minimizes visual impact and preserves the historical value of the structure. Additionally, obtaining necessary permissions and approvals from relevant authorities is crucial before proceeding with the installation.

Q:Hi. I hate the energy company. I hate my carbon footprint. I will likely move to a piece of property and put a decent-sized mobile home on it. I want solar panels so I can get my own power. I live in the state of Wisconsin. How much would this approximately cost? Would I need certain permits? How many panels can be used? Thanks for helping!: I'm not an expert on solar panels.... However, if you find they are expensive, I have a suggestion for eliminating a cost for heating... look into geo-thermal heating. It's a one time fee, they basically drill into the earth and heat your home with natural heat from underground. That wouldn't supply you all your power, but could cut down on the cost of solar panels, so you could use them simply for lights etc and not heat as well.... and I'm sure it would increase your re-sale value.

Q:How do solar panels affect the roof's structural integrity?: Solar panels do not significantly affect the roof's structural integrity. They are typically lightweight, and their installation involves mounting them securely onto the roof without causing any damage or weakening.

Q:Are there any restrictions or regulations regarding solar panel installations?: Yes, there are restrictions and regulations regarding solar panel installations. These can vary depending on the location and jurisdiction. Some common restrictions include obtaining permits, adhering to building codes and zoning regulations, and complying with utility interconnection requirements. It is important to check with local authorities and consult with professionals to ensure compliance with all applicable restrictions and regulations before installing solar panels.

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.: In 2007, the cost of solar photoelectric power was 38 cents US per kwh while the cost of coal power was 0.6 cents per kwh but consumer costs for power were 2 cents per kwh as additional coal power plants are not being built so wind and natural gas are being built. Without government incentives, solar power are not economic. However, the UK has extensive subsidies for solar, I would suggest that you learn how to perform Internal Rate of Return ( IRR ) calculations and Net Present Value ( NPV ) calculations to evaluate your financial decision, excel has an excellent =XIRR() function to do this with. Most people talk about payback periods but that's due to the poor level of financial education in the population and payback periods don't give you an appropriate evaluation of the time value of money. With solar power, it's a razor thin line of economics so you have to get the calculations right to know what's in your best interest, the laymen hearsay isn't going to do it.

Q:I'm trying to charge rechargeable AA batteries with a solar panel. What guage wire should I use to connect the panel to the batteries? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size? My panel is 4.8V 50mA.: You not only need a diode, but a circuit that opens the circuit if the voltage falls below a certain level. The diode is not the problem, but the batteries powering the solar panel when the voltage falls to low.

Q:A few months ago my dad said something about getting solar panels, and how green they were. I was just wondering if there were any companies that sold them and if they would actually make a big difference.: Yes there are companies that sell solar panels, many of them specialize in solar, a simple google search with your state or city name and the word solar should get you many results. There are actually two kinds of solar panels that get installed on homes, one kind creates electricity, the other heats up water. Depending on how large a system you installed, you could have all of your electricity or hot water powered by solar, which would mean you'd use less nonrenewable resources like coal, oil, or natural gas. The other difference the solar panels would make would be in your electric or gas bill, that number would go down right away, but you'd have to wait a few years before the money you save there would cover the cost of buying the panels, the number of years depends on your state, and the size of your system. Starting in January there will be a 30% federal tax credit, that would mean savings for every installation in the US. Also a lot of states now have a rebate program, which means the system is even less expensive.

Q:Can solar panels be used for heating a greenhouse?: Yes, solar panels can be used for heating a greenhouse. Solar panels can generate electricity, which can then be used to power heating systems in a greenhouse. Additionally, solar thermal panels can directly capture the sun's heat and transfer it to the greenhouse, providing an efficient and sustainable heating solution.

Q:i need how a solar panel works, if possible make as easy to understand as possible like because of this , this happens and if you could please put a web source you got it from: Sunlight (photons) hit a piece of silicon and knock electrons out of it. That causes a flow of electrons, which is electrical current. simple enough? a better explanation from wikipedia: A solar cell is a device that converts the energy of sunlight directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight such as solar panels and solar cells, while the term photovoltaic cell is used when the light source is unspecified.

Q:I'm just geting into electonics and stuff. So I am trying to make a simple USB charger. I'm looking for at least 4 volts output. What I've got is two solar panels (detached) a 4 AA battery holder, and a circuit board with an led on it (took the solar panels out of old lawn lights. I need more charge out of my panels (I think) so I tried attaching them. I soldered the positive wire from one to the positive connection on the other and negative wire to negative connection. After doing so and checking the multimeter, it says I have no output at all. How do you connect them?: You have to look at the power output of the cell. The first consideration has to do with voltage. A single cell with no load might output one volt or less. Wiring cells in series would double that output, at least in theory. (Internal resistance will lower the actual voltage.) You've wired the cells in parallel, however. Try unsoldering one electrode and then measure voltage output of each cell. There is still the issue of current output. I don't know if there will be enough with your setup. How many cells are there and what kind of batteries were they charging?
