- Q: Hey i am going to build a scale model house and demonstrate how you would use solar panels to provide energy. I am thinking of buying some kit solar panels and wiring up some lights to show how they power the home. Also i might hook up a battery in the house to show how you can store the energy. I might also have a large battery hooked up outside the house to represent a power plant that could provide emergency power. Any ideas or comments would be great. Thanks

- Q: Hi, I am starting to get curious about the pros/cons of installing solar panels - has anyone done it and is it worth it?
- In the state of Pennsylvania in the USA, a very basic 5KW solar installation will cost you $35,000. Of that you will recover approximately $28,000 over the next five (5) years between the State and the Feds. Making your net-cost something between $7,000 and $9,000 depending on various factors. All other things being equal in a standard household with fuel-based heat and window units vs. central AC, this system will provide roughly 50% of power required with a payback of approximately eight (8) years (with electricity at $0.4/kwh). The system has an estimated forty (40) year service life. Without _all_ the subsidies, the payback is longer than the estimated system life, especially if you consider the time-value of money. The life-cycle cost of a photo-voltaic array is horrendous. By that, I mean the total cost of producing the panels, installing them, and then removing them and disposing of them in an environmentally correct manner. All that added in and there is a negative payback. So, it all depends on what one defines as worth it. Putting the cost onto taxpayers via governmental subsidy to make an otherwise wretchedly expensive process viable may give you all sorts of warm-and-fuzzy feelings about renewable resources and reducing dependence on foreign oil and so forth. But the reality is that the true cost of solar panels exceeds that of nuclear power per KW delivered. Even today when nuclear plants start in the Billions-with-a-B in any currency you would care to name.
- 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 will need to wire several cells in series to obtain the necessary voltage, and you may need to wire several sets in parallel to obtain the required current. Series: Connect the + lead of one cell to the - lead of the next. You may chain any number of these together this way, and the output voltage will be the sum of the output voltages of each cell. The output current will be the greatest current of each individual cell. Parallel: Connect the + leads of each cell together, and the minus leads of each cell together. The output current will be the sum of the output currents of each cell. The Output voltage will be the greatest voltage of each individual cell. Picture this: think of the series cells as a column, connected from top to bottom. Think of the parallel cells as a row, with all the tops connected together and all the bottoms connected together. To arrive at the required voltage *and* current, you will need an array of cells, in rows and columns. The voltage will be the sum of each column, while the current will be the sum of each row. Most solar panels are arrays of individual cells. The arrays are then connected in the same fashion to provide the necessary combination of voltage and current.
- Q: How do solar panels impact the electric bill?
- Solar panels can significantly reduce or even eliminate the electric bill. By generating electricity from sunlight, solar panels can offset the amount of power needed from the grid. This means that homeowners or businesses with solar panels can consume less electricity from the utility company, resulting in lower energy bills. In some cases, excess solar energy can be exported back to the grid, earning credits that further reduce the electric bill.
- Q: I live in Los Angeles area, I see the ads that, they will install solar panel for $0. I would like to know what is the catch ?Thanks You.
- using solar panel in your life, you can save the electricity bill, also you are saving energy for our later generations. If more and more people are using solar energy, the mother earth will become more beautiful.
- Q: Can solar panels be installed on a warehouse or distribution center?
- Yes, solar panels can be installed on a warehouse or distribution center. In fact, these large flat rooftops are ideal locations for solar panel installations due to their ample space and reduced shading. By harnessing solar energy, warehouses and distribution centers can significantly reduce their dependence on traditional grid electricity and lower their carbon footprint.
- Q: Im curious because I read about a boy who invented a 3d solar panel, using a pyramid he designed a solar panel that collects light more efficiently. Now I have a question. Why cant I design a solar panel that takes adventage of convex and concave mirror's and use a surface that collects light and then focus's the suns energy into a beam and take the beam into a chamber where the solar panels are sitting and surround them with mirrors as well, so any light not obsorbed by one particular spot is reflected to another area for reabsorbtion. I know solar panels dont absorb light but perhaps that will allow more light to create the effects it needs.
- I don't know anything about the 3D thing. You cannot get more energy out, than goes in. Energy will only hit the mirrors. With some loss of efficiency they would reflect a focused beam into the chamber, where with some more losses would reflect it to the solar panels. It would be more efficient just to expose all the panels to sunlight.
- Q: Is it possible for the everyday person to increase the efficiency of solar panels that they own? If so, how is it done?
- If you have a way to keep silicon panels cool, that really helps. On a hot summer day, our array was down 20% in production. I sprayed a hose to wash the panels, and for a few minutes, the power spiked to 20% ABOVE normal. The usual thing to do is mount the panels exposed to the wind if you can, or at least 8 off the roof otherwise. A few lucky souls with access to free stream water on their property have been known to use water cooling under their panels.
- Q: Can solar panels be installed on golf courses or recreational facilities?
- Yes, solar panels can be installed on golf courses or recreational facilities. The large open spaces and ample sunlight available at these locations make them suitable for harnessing solar energy. Additionally, solar panels can help these facilities reduce their carbon footprint and lower their energy costs.
- 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.
