Active Ventilation provides innovative ventilation solutions including roof vents, attic fans, solar-powered vents, dormer and soffit vents for residential and commercial structures. All of Active Ventilation Products are manufactured in the USA.

Why Choose an Attic Solar Fan over an Electric Powered One?

The attic is typically a quite problematic area in the home. Have you noticed how through the warmer months of the year the attic is hot enough to fry bacon in (without a pan)? During summertime, heat from the sun radiates to the shingles of the roof, from there to the attic, and from the attic to the entire home. Unfortunately this problem cannot be solved by simply waiting for the sun to go down, as the attic stays hot for much longer after. Having insulation slows the progress without eliminating heat entirely. A solar attic fan will ventilate the attic area without running up the energy bill or running the money out of your pocket.

Types of Ventilation: Passive v. Active

Passive Draft Air Convection

The type of ventilation an attic house fan provides plays a major role in the efficiency of the system as well as the energy usage in your home and what it costs. Gable vents, ridge vents, and dormer vents fall into the category of passive, or natural, ventilation. What this means is that as the hot air in the attic rises, it should pass through the vents to produce a natural draft through the attic. However, this method is not effective in lowering the attic temperature. Turbine vents are just as unsuccessful in properly ventilating the attic, as they are not capable of moving much air, experience mechanical issues regularly, and depend on wind to provide power.

Active Draft Air Convection

Attic solar fans are placed in the category of active attic ventilation. Air coming from outside is pushed through the attic and out of the vent. Through this method, attic air is exchanged more frequently every hour as opposed to the method of passive ventilation. These fans are capable of providing cool air to the entire attic space all through the day, as they bring on more of an air draft throughout the attic. In addition, the process of active draft air convection allows the solar attic fan to provide the attic with cool air during the entire day.

Choosing the right Solar Ventilation Fans

Solar ventilation fans can be placed in two categories of performances: 10 watt and 20 watt or higher fans. While the 10 watt solar attic fan is less expensive than the higher wattage fans, it is capable of moving only 850 CFM at the most. These fans are ideal for attic spaces that cover 1200 square feet at the most. If you have an attic that covers more square feet, you can choose to either purchase many low wattage solar attic fans or install a higher wattage fan for the attic.

The amount of air moved by lower wattage fans is fairly minute when compared to the maximum 1550 CFM of airflow the higher wattage attic solar fans can handle once fully exposed to the sun. These solar ventilation fans are more suitable for the average home, since the attic covers more than 1200 square feet. The DC motor on the solar attic house fan is powered by a small panel. The 20-25 watt panel is activated once it has been exposed to sunlight.

Environmental and Financial Benefits

The common attic house fan is generated using residential energy. Solar ventilation fans are powered entirely by the sun. This lessens the burden on your energy supply at home. The attic will continue to stay well ventilated, as these fans minimize the amount of spaces that require cooling. Having a well-ventilated attic allows you to better control the temperature in the home. The need to change the thermostat settings will be greatly reduced, as the attic will no longer be releasing warm or cold air into the rest of the house, allowing you to save energy in the home.

Energy savings in the home translate to savings on the energy bill. The money saved is the money that has been used to power a fan in your attic that is not really providing enough ventilation. The solar attic fan costs absolutely nothing to operate. The fans move a maximum 1550 CFM of attic air once fully exposed to the sun. While the exact amount of savings is dependent upon factors including climate, electricity rates, and attic size, the average attic solar fans pay for themselves after a period of 1-2 summers.

Solving the problem of proper attic ventilation does not have to be a difficult task. A solar attic fan is powered entirely by the sun. The energy provided by the sun does not add to the burden on your energy supply. By reducing the amount of energy used, you are also decreasing amount of emissions from your home. In addition, attic solar fans ventilate the attic without costing you a penny. You can rest easy knowing that the attic is not sending burning hot air into the home, and the energy bill is no longer burning a hole in your wallet.

The Sun Switch senses the position of the sun for a solar tracker. This is a test circuit to see if green LEDs can provide TTL logic levels into a motor control circuit. When green LEDs are exposed to direct sunlight they will generate a voltage. This circuit uses three LEDs in series which produce about 5.1 volts when aimed directly at the sun. The circuit and pics will be posted on www.greenwatts.info

Photovoltaic Cell Powered Through Solar Power

Photovoltaic cell is also known as a solar cell powered by solar power. It is a device which helps in converting sunlight into electric current with the help of photoelectric effect. It is based on the theory that some materials release electrons when they hit the rays of photon in the light. This produces an electric current.

The cost of early solar cells was 286 USD/watt and it also reached efficiencies of 4.5–6%. In 2009, the PV cells with highest efficiency were being produced commercially by Boeing or SpectroLab at about 41%. Although similar cells with multi-layer were close but they were very expensive. However, they were used only for the most accurate applications. Thin film PV cells have been developed of late and they are being made in bulk as these are cheap and less fragile, but are at the most efficient by 20%. The most recent development is the demonstration of a new design with the efficiency of 85% in plain sunlight and that of 95% efficient at different wavelengths. It has been produced only experimentally in the laboratory as an example, but it may have the possibility of low cost production in bulk in the future.

The earliest application of the cells powered by solar power was a back-up power source to a satellite in 1958. The photovoltaic solar panels powered by the solar power gained application in things other than the satellite only after the energy crisis in the 70′s. Since the cost of solar cells was high therefore, it was difficult to generate it in the remote areas. It includes powering of telecommunication stations, off-shore oil rigs, railroad crossing, and navigational buoys with the help of solar power.

Germany became the leading country in the photovoltaic market all over the world since its capacity has increased from 100 MW to 4,150 MW between 2000 and 2007. Spain became the largest in its installation. Mean while, France, US, Italy, South Korea and other countries have been increasing the usage of solar power in their own countries in terms of power output of domestic photovoltaic devices.

Since the Economies of scale showed an increase in the production of photovoltaic power and certain improvements with the help of solar power, therefore, its price came down. One of the main causes was the oil prices which stimulated a rapid rise in its production. This power generation method had a moderated production growth of 15% per year from 1984 to 1996. However, its production growth has increased to 30% per year in the 1990s.

Another new method of electricity generation from solar power is concentrating photovoltaics. CPV systems help in employing sunlight and concentrating onto the photovoltaic surfaces for the purpose of production of electrical power. All varieties solar concentrators can be used. They are often mounted on a solar tracker for keeping the focal point on the cell as the sun moves across the sky in order to generate solar power. Tracking can help in increasing the output of a flat panel photovoltaic by 20% in winter and by 50% in summers.

Make Cheap Solar Panel-Learn How To Make Cheap Solar Panel

The greatest thing about solar power is that its potential is virtually unlimited. Contrary to the popular belief learning how to make cheap solar panel is easy. You just need to know how to make your own renewable energy source and today I am going to tell you exactly how to make solar panels.

Before you start to make cheap solar panel, you’ll need to learn some basics on how exactly do solar panels work. This way, the entire process will be much easier to handle.

The procedure starts with solar modules. They are the main components exposed directly to sunlight. Their major role is to convert the sun’s energy into usable electrical power for electrical appliances. To have them properly installed, solar modules are to be mounted on a steel frame and positioned on your roof top.
Power created by the solar modules is converted from Direct Current (DC) to Alternating Current (AC) through a inverter. Usually, Alternating Current (AC) is the usable electrical power that we need to power the home appliances.

Next, the electrical power transfers from the inverter to the electrical service panel. The electrical service panel is used for distributing the electrical power to different parts of your house or office for use.

The unused electrical power produced by the solar panels will then be brought into the grid all the way through the utility electric meter. As a result, the meter will be made to spin backwards and this establishes a credit with the utility company in offsetting future usage. This method is known as Net Metering and is permitted by State Level Electricity Policy.

Learning how to make cheap solar panel isn’t really complex. You don’t need many skills beyond being able to handle wiring & basic tools with care and safety measures.

The raw materials needed for building solar panels include:-

1. Solar Cells
2. Sheet Plywood
3. General Tools (Drills, screwdrivers, woodwork glue etc)
4. Clear PVC Sheeting
5. Copper Wire

All these raw materials can be easily bought from the local electrical store. Photovoltaic cell is the only component that you might have to search online and it can be found easily on eBay.

Common Questions About Solar Panels as Water Heaters

To put it simply, solar electricity is the use of photovoltaic solar cells to convert the photon power from the sun into electrical energy. In turn, expounded electrical energy is used to provide power to the household gadgets from the cell telephone charger to the lights.

In most residential applications, the solar cells are mounted in a fixed position preferably on a south-facing roof. Other choices include ground-mounted racks on fixed positions as well as solar panels on tracking systems, which can be moved on their axis to keep the panels oriented towards the sun at every point during the day.

- Solar Electricity Workings

Photovoltaic cells are the main components of a solar electricity system, with the inverter and the battery as the other two components. When sunlight strikes the photovoltaic cells, the sun’s energy excites the electrons in the cells that generate the electrical voltage and current. In turn, the thin wires on the photovoltaic cells’ top layer carry the electric current into the circuit and, from there, to the appliances and lights.

It must be noted that the energy produced by the solar cells are in direct current. Though you can purchase special appliances running on direct current, it is a better option to install an inverter to convert direct current into AC, which is the current on which almost all home gadgets are made for.

Benefits of Solar Electricity

there are lots of advantages to using solar electricity in your home such as :

- Savings on electricity bill is possible since there’s smaller dependence on the main grid. In reality, you can run your electric meter backwards in the shape of contributions to the main grid, which is then subtracted from your bill!
- cost of the house is increased since potential buyers will need to pay more for the cost-saving alternative already installed in the home.
- System can pay for itself in 3-4 years’ time and, from then on, everything is pure savings.
- there isn’t any need to fret about upkeep costs as there’s very tiny to it. Add in the incontrovertible fact that federal and state tax breaks and incentives are available and you’ve a system that’s highly reasonable.
- Smaller dependence on foreign oil, which is superb for the economy indeed.
- Plus, with more green jobs generated with the increasing patronage of solar cells and other kinds of green energy, the economy can be pulled out of its doldrums.

Of course, the most vital benefit is that the environment is defended from further degradation brought on by the reliance on fossil fuel-generated electricity.

Types of Solar electrical Systems

There are 3 kinds of solar electrical systems currently in application for residential houses. Your decision will depend on a spread of factors including location, available budget and energy goals and wants to name a couple points to consider.

First, the grid intertied solar electric systems generate electricity for routing into the main electrical utility grid. Second, the grid-intertied solar-electric systems with battery backup that still provides power even in the event of blackouts. 3rd, the off-grid solar-electric systems are compatible for remote locations.

Actually, solar electricity is an especially valid option when you want to save on your electricity bill as well as save the environment. You only need to rough up on the details in order to maximise its potential in your life.
