Solar 101: Photovoltaic (PV) Solar Power

The most recognizable way to produce solar power, photovoltaic (PV) cells are used in everything from calculators to prototype automobiles.

These cells allow consumers to produce their own electricity for any use they please. Excess energy produced by PV cells can be sold back to the local utility company in many areas.

Saving and making money with a PV system

Most of the PV systems in use today are tied to the traditional power grid saving homes and businesses money while they use the solar power generated by the system and providing a cheap nba jerseys valuable back-up in cases where the amount of energy generated by their system may not match their energy usage needs.In some circumstances, excess energy may be produced and sold back to the utility provider.

In 2005, Governor Christine Gregoire signed senate bills 5101 and 5111 making Washington arguably the most progressive state in the union in terms of renewable energy production.The bills allow for utility companies to pay up to a $2,000 per year rebate for the production of energy through renewable means by residents and businesses and write it off of the amount they pay in state tax.

Washington Net Metering Programs

Since March of 1998, Washington state utilities have been required to provide net metering programs that monitor production of electricity by solar, wind or small hydroelectric power and issue credits back to the consumer/producer if the electricity generated is more than the electricity used.Contact your local utility provider to get the details on their net metering program.

The real profit margin in your PV system

More so than any credit you might receive from your utility company, the biggest benefit in your PV electric system is going to come in the money that you don’t pay on your utility bill. PV systems can provide as much as 1,200 Kilowatt hours per 1,000 watts of PV panel installed providing significant savings on your utility bill.

PV Systems

On-Grid Solar Electric Systems

These systems are tied into the standard electric utility system and supplement your power needs meaning that you need to purchase less electricity.When the system generates more power than you Water use, the excess power is put back into the power grid for use by other utility customers. In Washington State, the utilities are required to compensate consumer/producers for the power put back into the system through a system called Links net metering. A straight on-grid system is EIGHTY6 dependent on the utility to function and will not preserve power during a blackout.The addition of a storage battery of the system will allow the system to light a home or business for the life of the battery during an outage.

Off-Grid Solar Electric Systems

Off-grid systems are primarily used in rural areas without standard electric service. They are dependant on battery storage to supply power during hours when the sun is not out or not bright enough to supply power for all of the users needs.In most cases, off-grid systems require more careful monitoring of electrical usage.

PV System Components

Solar Panels (also known as the PV array) are the most visible and defining portion of the system and are rated by the cheap mlb jerseys watts of electricity they can produce in ideal conditions.Two thin layers of semiconductors are sandwiched together within the cell.The semiconductors Renewable react to the photons in sunlight by generating a small DC current which is then transferred into the system where is can be prepared for use by the consumer. Modern solar panels are lightweight and able to withstand inclement weather conditions including hail stones in 世界的人気で国外輸出禁止になったスーパーフード「テフ」 most cases.

The PV disconnect is essentially a circuit breaker for the system that can be thrown to stop the flow of electricity from the PV arrays and allow for maintenance.

Charge Controllers protect the batteries in the system from overcharging by stopping the power flow from the PV array when the battery is sufficiently charged.

Battery storage store the energy created by the PV array for later use.

System monitors (also called the battery monitor) give readings on how much power is available within the system.

Main DC Disconnects allow for the system to be shut down between the battery and the inverter and prevents electrical fires within Sherry the system.

The inverter converts wholesale mlb jerseys power from the DC current created by the PV array into AC power that can be used in your home.

The breaker panel is the control point for your home’s electrical system.
