The fuel for solar panels cannot be bought or monopolized. It is free for all to use. Once you have solar panels on your roof, you have an essentially independent source of electricity that is all yours.
This is important for individual homes, but also for communities, towns, parishes, and even companies. Putting solar PV panels on your roof is likely to save you tens of thousands of dollars. Solar energy creates absolutely no pollution. This is perhaps the most important advantage that makes solar energy so much more practical than oil. Oil burning releases harmful greenhouses gases, carcinogens and carbon dioxide into our precious air.
Solar PV Panels are a solar-electric system’s defining component, where sunlight is used to make direct current (DC) electricity. Behind a PV panels shimmering facade, wafers of semiconductor material work their magic, using light (photons) to generate electricity what is known as the photovoltaic effect. Other components in your system enable the electricity from your solar-electric panels to safely power your electric loads like lights, computers, and refrigerators.
A standby generator is a back-up electrical system that operates automatically. Within seconds of a utility outage an automatic transfer switch senses the power loss, commands the generator to start and then transfers the electrical load to the generator. The standby generator begins supplying power to the circuits. After utility power returns, the automatic transfer switch transfers the electrical load back to the utility and signals the standby generator to shut off. It then returns to standby mode where it awaits the next outage. To ensure a proper response to an outage, a standby generator runs weekly self-tests. Most units run on diesel, natural gas or liquid propane gas.
Automatic standby generator systems may be required by building codes for critical safety systems such as elevators in high-rise buildings, fire protection systems, standby lighting, or medical and life support equipment. Residential standby generators are increasingly common, providing backup electrical power to HVAC systems, security systems, and household applicances such as refrigerators, stoves, and hot water heaters.
