Yes. According to an article published by the national renewable Energy Laboratory (NREL) today's solar panels will produce as much energy as it takes to make them in about four years.

The expected life of a typical solar panel is about fifty years. Today's solar electric systems have 20 to 25 year warranties.

Yes. Solar electricity systems that are tied into public utility systems sell power back to the utility grid in the summer, while still producing smaller amounts of power on cloudy days. In the summer, when electricity use is highest, solar systems generate the most power, thereby offsetting some of the increased demand. The result is less dependence on non-renewable energy and more clean power from the sun.

If you are connected to a utility and wish to produce your own electricity, Oregon's "net metering" law (ORS 757.300) requires utilities to let you exchange any surplus power produced by your solar electric system for utility power you use when your system is not producing enough power to meet your needs (such as at night). Your meter simply spins backwards during sunny portions of the day when you are producing more than you use.

individual solar cell that is 10 x 10 cm in size generates approximately 0.5 volts and 2.4 amperes of electricity in full sunlight. That corresponds to approximately 1.2 watts of output. In most cases, these values, most importantly the low voltage, are too low for practical use. Therefore several solar cells are typically connected together (in a row) and the cells are also 'packed' between sheets of glass or plastic to provide better protection against environmental influences.

This depends on greatly on the time of day, the day of the year, the geographical location, and the weather. In optimal conditions the array should be able to generate up to 1800 Watts. To put that in perspective that is about the same amount of power as some hair driers use or enough power for 30 60W light bulbs.

Different technologies make different amounts of noise. Grid-tied inverters make almost none. Battery back-up systems are louder; you might not want to mount them on the wall behind your bedroom.

Energy from the sun can be directly converted to electricity using solar cells, also known as photovoltaics or PVs. The solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity. Although individual PV cells produce only small amounts of electricity, PV modules (see "What are "PVs") are manufactured with varying electrical outputs ranging from a few watts to more than 100 watts of direct current (DC) electricity.

Solar thermal panels are rated with efficiencies ranging from 50% to 78%, producing about 1000 BTUs per square foot per day - or 290 Watt-Hours per day per square foot. Electric solar panels have efficiencies ranging from 11%-15% and produce about 12 watts per square foot - or 72 Watt-Hours per day per square foot. Also, electric panels typically cost more than thermal panels. For the same financial investment, a thermal system produces 5 times more energy than an electric system.

Solar, wind, geothermal steam, biomass, and small-scale hydroelectric sources are considered "green power.

The practicality of using solar power varies due to a wide range of conditions. If you are within 1000 ft. of a power outlet, we recommend using the transformer for a steadier, more constant charge. If you choose to use solar power, see the Solar Chart Powering Accessories which outlines the recommended number of panels (generally one or two) for your region of the country.

The array size you need depends on your average electrical usage, climate, roof angle, shading problems and many other factors. To approximate the array size you need, multiply your average daily electrical demand in kilowatt-hours by 0.25. The result is the approximate size of solar array, in kilowatts, needed to meet your electrical demand.

Solar CREEK has enlisted a local business partner who will pay for the equipment and installation. Through the use of state and federal tax incentives, the Oregon Energy Trust, power sold to the utility grid, and donations from the community, the business partner will be reimbursed for the entire cost of the systems. Due to the state and federal subsidies for implementing solar technology, for every dollar donated by citizens, government funding will match it with three.

Currently, it costs three to five times more to use solar electricity than utility power. State, federal and utility incentives can make solar systems competitive with other power sources without the hidden environmental costs of those sources. Photovoltaics are expensive to produce because of the high cost of semi conducting materials. Cost reductions can be achieved by reducing manufacturing costs. As manufacturing capacity increases, costs of manufacturing decrease.

Answer - Solar panels today are more efficient than ever. Remember, solar power generation depends on intensity of light, not sustained, strong direct sunlight. Even when it’s overcast, solar panels will produce clean electricity to help power your home.

If set to SAVE, the sensor goes into a standby sleep mode saving battery power. In the save mode, the temperature sensor is polled about every 40 minutes rather than every 20 minutes. The other sensors respond slightly slower to events that occur in save mode. Unlike the brightness and contrast settings, the quality setting does not affect the live camera view. It only has an affect on archived image captures.

Solar Power is the energy of the sun, converted into eco-friendly electricity, which can then meet your daily ???power' requirements.

When biomass is burned, it produces heat (as in any simple fireplace or furnace). In most power plants (steam-cycle or steam-turbine systems), this heat is captured by boiling water to generate steam, which turns turbines and drives generators that convert the energy into electricity. New technologies now being evaluated include several types of biomass gasifiers in which biomass is heated to convert it into a gas.

Sometimes yes, and sometimes no. Each solar installation is different - we work closely with your solar company to coordinate the installation.
