Tags: , , , , , , , , , , , , , , , , , , ,

Wind turbines and solar panels are becoming a popular means of electricity generation. They allow you to live at a remote place and still be able to operate your electrical appliances without needing to run a generator.

Solar Energy By Using Solar Panels

Sun is a vast and inexpensive source of energy for the entire planet. It produces heat and light. While the heat is being used to warm our earth, the sun light can be effectively used to generate electric current.

1. Solar Panels

Solar panels are the devoices that use the sun light and convert into electric current> these cells are composed of silicon and once the light falls on these cells present in arrays of solar panel, the electrons are freed which cause the current to flow. In this way, electricity is generated without any harmful emission.

2. Factors Affecting Solar Energy

Since the solar energy is obtained from the sunlight, any thing affecting its intensity is going to affect the amount of electricity produced. If the solar panels are placed at a place where they receive very little light or they receive the light for short intervals, their production shall be very limited. On the other hand, the exposure to intense light will generate higher amount of electricity. The weather conditions also affect the solar panels.

3. Solar Power System

A solar Power system is composed of a solar panel connected to the battery. The battery is charged by the current produced by the panel and this battery powers the appliance in the homes.

Working of a wind turbine is explained on four bases. Wind mill usually consist of three blades when these blades come in contact with the wind the turbine spins. A shaft of the turbine is connected to the generator. When the turbine spin the shaft spins the rotor of the generator thus electricity is produced.

Wind speed

Wind speed

The most important factor which effects the generation of electricity is wind speed. Knowing wind speed you can easily determine the amount of electricity Coemi wind turbine will produce. Wind speed is measured by inbuilt anemometer. The information from this instrument is carried to a controller which starts up the turbine even if the wind speed is 2.5m/s and convert energy obtained into electrical energy. It adjusts automatically its position to prevent all setup from damaging when the wind speed is very high up to 40mph.

Importance of blade design

Blade design matters a lot in generating process. The design of the blade should be such that can stay strong and operate in bad climate conditions. The blades are light in weight and are start generating process at low speed from 2.5m/s. Read the full story

Heat can be immensely useful. Only the correct means of using it must be known.

Utilizing Heat Pumps

Utilizing Heat Pumps

It can be used to warm the air outside or even cool it. It is very capable and efficient in its working as it will maintain the temperature to a bearable limit. It uses the energy that usually goes waste.

Increasing Popularity Of Heat Pumps

Heat pumps are gaining in fame rapidly  due to tax incentives, rebates and the inherent energy and cost savings in using a more efficient heating and cooling system. The main barrier for heat pumps is the high upfront costs, although tax incentives and energy savings can recover those costs some years, depending on the system and climate.

How Heat Pumps Work

Thermal pumps are typically not powerful enough to handle the entire heating and cooling load for an average home. The thermostat should not be twisted often and left at a standard 16-17 degrees. Read the full story

For generating electricity, generators are required and solar generators are the most incredible alternatives. The generators consist of a number of parts that work jointly for producing electricity. The major parts of a solar generator include inverter, battery, controller, and most importantly solar panel.

Solar panel

Solar panel

The basic function of a solar panel is to collect the solar energy as it is mounted on the top of the roof. It also converts the sunlight into usable electricity. The other reliable replacements for the solar panel are solar tiles and solar shingles.

Function of inverters

Inverter is a device that is used to convert the direct current into alternating current. Inverters used in solar generators also perform the same function. Once the current is converted from DC to AC, you can use it for any household purpose. Another important part of the generator is the grid-tie inverter. The basic function of this inverter is the connection of solar power system and the utility grid of the company.

Back-up source (battery)

A battery is installed to fulfill the purpose of storing the electrical energy. Storing is necessary for back-up usage. The charging of the battery is controlled with the help of a charging controller. It monitors the charging of the battery continuously and prevents it from the overcharging and undercharging conditions. Read the full story

Solar Cells by Generations

Tags: , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,

There are four distinct generations or categories of solar photovoltaic (PV) technology, the electricity generating heat of the solar panel and solar cells. These generations or categories represent a kind of timeline of innovations and changes that have been introduced in solar power technology. These generations and categories are separated by characteristics like application, semiconductor material and stage of development.

First Generation of Solar Cells

First Generation of Solar Cells

It is not only the oldest but also the most commercially widespread generation of the solar cells. This generation is characterized by conventional silicon wafer solar cells. These solar cells utilize thinly sliced silicon wafers that act as semiconductor. It is an important part of the solar cell that absorbs photons and by exciting its electrons to generate applicable electric current.  Currently, silicon solar cells are capable of controlling roughly 80 percent of the photovoltaic market due to their higher conversion efficiency. Although, this efficiency is expected to alter as the next generation of solar cells is more efficient and cost effective.

Second Generation of Solar Cells

This generation of solar cells is characterized by thin film and building integrated technology. The solar cells of second generation are thinner, more cost effective and more flexible than their counterparts of first generation. In this generation the types of semiconductor material has broaden. New materials have introduced that include amorphous silicon to calcium telluride and copper indium gallium selenide. It is expected that second generation’s thin-film solar cells will take over the market and eliminate the first generation’s solar cells from the trend within 5 to 10 years, but so far it is just an expectation.
