What is unique about Windterra?s products??
Windterra is delivering a new paradigm for green energy ? small wind turbines! No one has an ?affordable? small wind generator for the residential and commercial markets. There are wind generation products, but they are usually Horizontal Axis Wind Turbines directed more towards farm/rural market, requiring a tower installation for greater speeds and laminar wind-flow. The Windterra roof-mounted VAWT has a number of distinct advantages over costlier HAWT systems:
Q. How is solar electricity generated?
Energy from the sun can be directly converted to electricity using solar cells, also known as photovoltaics or PVs. PV modules are manufactured with varying electrical outputs ranging from a few watts to more than 100 watts of direct current (DC) electricity.
Q. What are ?PVs? (photovoltaics)?
A solar or PV cell consists of semi conducting material that absorbs the sunlight. PV cells are typically combined into modules that hold about 40 cells - About 10 of these modules are mounted in PV arrays.
How is electricity measured?
Electricity is measured in units of power called watts. One watt is a very small amount of power. It would require nearly 750 watts to equal one horsepower. A kilowatt represents 1,000 watts. A kilowatt-hour (kWh) is equal to the energy of 1,000 watts working for one hour. The amount of electricity a power plant generates or a customer uses over a period of time is measured in kilowatthours (kWh).
Q. Can solar power work in Oregon?
Yes. Solar electricity systems that are tied into public utility systems sell power back to the utility grid when production from renewable energy harvestment systems exceed to energy consumption, with the advancement of solar technology, solar panels are still able to collect energy on cloudy days. The result is less dependence on non-renewable energy and more clean power from wind and the sun.
Q. How does a solar electricity system sell power back to public utilities?
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. Your meter simply spins backwards during sunny portions of the day when you are producing more than you use. At the end of the billing
period, you are only billed for the net energy you use.
If I install a grid-tied system now, can I put battery-backed system onto it later?Battery-backed and grid-tied only systems use the same solar panels; The difference is replacing the power inverter and purchasing the addition of batteries.
How can I tell if my building is suitable for Photovoltaic Panels?
Several aspects will need to be evaluated to determine if your home is a good solar site, such as orientation, space available, shadows on the space available and your current electricity usage. The best site will be one with adequate south-facing roofs that have no shade.
What costs are involved?
Costs involved are the cost of the PV panels and hardware, installation, electrical building permit, conduit, miscellaneous wiring. For an up to date price quote, please call us at (971) 218-2564 or email to email@example.com
