what colour can solar panels be ?
- Panels can come in a selection of colors, and trimmed in a variety of frames. Most are dark, black, blue or reddish in hue. Concentrators may appear white from a distance. Kinetic back up is possible in the form of a flywheel. Not very common but it is out there. Another form of kinetic backup that is used by some power companies is hydro. When the sun is out and the system is producing more than is used, the excess can be used to pump water uphill to a holding tank. Then when there is a demand, the water is allowed to flow back down turning a turbine to generate electricity.s
How do Solar Panels work?
- solar panels are made of solar cells.Solar cells are mainly made of a semiconductor called silicon,when sunshine on it,solar energy is converted into electrical energy by photovoltaic.The energy knocks electrons loose, allowing them to flow freely.This flow of electrons is a current, this current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce.s

Anyone have or know someone who has solar panels installed in their home? Is it worth getting?
- Solar electricity is electricity, it is just coming from a clean source rather than coal or oil burning generators. The solar panels make DC power, and the inverter converts it to AC and syncs it up with the electricity you buy from the electric company, it all goes into the same pool, there is no difference between them. gr8sk8rgold - Yes, you are right, installing a large solar system on your house can cost as much as a luxury car. What's the return on investment on that car? How has that car improved the environment? People never ask what the ROI is on anything they buy for their house, except for the solar system. Not sure why. However, the return varies greatly depending on where you live. In some European countries, feed-in-tariffs made the return almost immediate. Ontario, Canada just launched a program that can make a solar system earn you money. In the USA, the federal gov't will give you a 30% tax credit on the installed cost, and some states have rebates and incentives that can pay for a large percentage of the system. If you are building a new house and roll the cost into the mortgage, it'll barely change the monthly payments. You should absolutely first invest in conservation. It is much cheaper to save electricity than to make it. For every $ you spend on conservation, that's about $4 less to spend on solar.s
How would you connect a solar panel to a fan?
- Wire is always good. You may need some electronics to convert the voltage put out by the solar panel to what is required by the fan. Some batteries might be nice so that the fan will run when the sun is not shining.s
