home solar energy
from Daniel Stouffer

You are contributing to a cleaner environment by upgrading to solar generated electricity. You are also taking a step toward energy independence when you begin using solar power in your home.

To better understand solar electric systems and how they work, you first need to understand the technical components making up a residential solar energy system.

New solar rental services are emerging that offer solar power in new and simple ways. There are a number of solar panel rental offers now on the market. They offer energy efficiency in your home, better control and tracking of home power, and make a home’s electricity services more reliable, and renewable.

This article explains, defined, and illustrates the parts and pieces going into a residential solar energy unit.

Solar Photovoltaic (PV) Panels

The primary components of a home solar system are the Solar (PV) panels. These panels utilize solar cells to convert sunlight directly into home electricity. A group of solar cells hooked together make a solar panel. A single solar panel can produce 250 watts (w) of electricity when the sun is shining at maximum capacity. The panels then route power through an inverter where a controller determines how to distribute the power throughout your home.

Solar Energy Controller and Inverter

The controller is the device that monitors and manages the distribution of electricity produced by a residential solar energy system. Its capability extends even further by monitoring and managing the flow of energy between the house, the solar (PV) panels & system, and the local utility company. Often these controllers also have the ability to manage secondary storage through the use of batteries for more flexibility and control.

Coupled with the controller is the brains of the operation; the inverter. An inverter is in essence an electronic circuit that converts direct current (DC) to alternating current (AC). An inverter allows the 12 or 24 volt DC power produced from solar panels to supply AC power to operate all of the electrical needs around your house.

Solar Array Mounting and Connection Components

Connection components are made up of electrical wiring and the rail mounting structure. Several solar panels are arranged into a grid, secured by a rail mounting device, and connected together to make a solar (PV) array. Electrical wiring is needed to connect the solar panels to the controller, then to your meter box, and then to your utility company via the existing electricity grid. Little additional solar energy equipment is needed, other than the panels, controller and inverters, wiring, and the roof mounting system.

The mounting rail is another simple structure that secures your solar (PV) array to your roof with the little need to drill holes through your singles. It is constructed with sturdy materials and engineering, allowing for quick assembly of the solar panels.

Rental Options for Residential Solar Energy Systems

Homeowners now have the ability to generate electricity right at home in safe, simple, and environmentally conscious way. Residential solar energy systems convert sunlight (i.e. photons) directly into usable home electricity. Residential solar energy systems, now offered to homeowners on a rental basis, provide a new source of reliable electricity and they enhance electric services without expensive investments in solar purchases.

In a future article, we will continue this series related to residential solar energy systems. We will explain in common terms how to measure the power of the sun. One objection often voiced by homeowners researching home solar power relates to the quality of the sunlight.

Is too cloudy? Is it too foggy? How does snow effect solar cell output? We will show how to calculate your sunlight hours and to determine if your part of the country gets adequate sunlight hours to have a solar system make sense.

alternative energy for the home
from Reginald Ross

The Ocean, Nuclear and Solar Power are forms of alternative energy which can be developed.

Ocean Thermal Energy Conversion (OTEC) is a potential alternative energy source that needs to be funded and explored much more than it presently is.

There are three kinds; closed, open and hybrid cycle of OTEC.

“Closed Cycle” uses a low-boiling point liquid such as, for example, propane to act as an intermediate fluid. The OTEC plant pumps the warm sea water into the reaction chamber and boils the intermediate fluid. This results in the intermediate fluid’s vapor pushing the turbine of the engine, which thus generates electricity. The vapor is then cooled down by putting in cold sea water.

“Open Cycle”. The sea water itself is the driver of the turbine engine in this OTEC format. Warm sea water found on the surface of the ocean is turned into a low-pressure vapor under the constraint of a vacuum. The low-pressure vapor is released in a focused area and it has the power to drive the turbine. To cool down the vapor and create desalinated water for human consumption, the deeper ocean’s cold waters are added to the vapor after it has generated sufficient electricity.

“Hybrid Cycle” There are actually two sub-theories to the theory of Hybrid Cycling. The first involves using a closed cycling to generate electricity. This electricity is in turn used to create the vacuum environment needed for open cycling. The second component is the integration of two open cyclings such that twice the amount of desalinated, potable water is created that with just one open cycle.

Developing Nuclear Power as Alternative Energy

Nuclear power plants are very “clean-burning” and their efficiency is rather staggering. Nuclear power is generated at 80% efficiency, meaning that the energy produced by the fission reactions is almost equal to the energy put into producing the fission reactions in the first place. There is not a lot of waste material generated by nuclear fission—although, due to the fact that there is no such thing as creating energy without also creating some measure of waste, there is some. The concerns of people such as environmentalists with regards to using nuclear power as an alternative energy source center around this waste, which is radioactive gases which have to be contained.

Solar Energy Collecting as an Alternative Energy Source

Solar powered electricity generation is certainly good for the environment, as this alternative form of producing energy gives off absolutely zero emissions into the atmosphere and is merely utilizing one of the most naturally occurring of all things as its driver. Solar collection cells are becoming slowly but surely ever more practical for placing upon the rooftops of people’s homes, and they are not a difficult system to use for heating one’s home, creating hot water, or producing electricity. In the case of using the photovoltaic cells for hot water generation, the system works by having the water encased in the cells, where it is heated and then sent through your pipes.
