Solar Power for Homes Now

Posts Tagged ‘Solar Power’

In this article we are taking a closer look at what we believe are the most important both renewable energy and green energy sources out there. This is where the focus and innovation should be put if we want to keep the earth in a healthy condition to generations to come in the future. Let’s dig in deeper and see what this is all about.

The Sun

The sun is the source of all the other energy forms we are discussing in this article, so it’s only natural to mention it first. The sun is going to keep shining for millions of years in the future so we can safely label it as renewable. In the last couple of years the technology of photovoltaic cells have blossomed. These are able to produce electrical energy from the photons the sun emits towards the earth.

The Wind

The wind is like we mentioned above energy that comes from the sun. Different temperatures make sure that the wind is always moving particles around in the air. These particles have motional energy. How can we harness this energy? There are many methods for this. One of the most common methods to use this energy is through sailboats, but to get electrical energy out of it we need to use wind turbines. The wind power pros and cons list is still not as economically as we want it to be, but with improved technology and more incentives from the governments, it will soon be.

Waves and Tides

There is a lot of research being done on harnessing the energy from waves and tides. While there is still a lot more work that needs to be done on this area, it looks very promising. Only the future will tell if we have room for such technologies.

Geothermal

Lastly, but still a very important method, is geothermal systems. These require to dig down pipes deep underground to collect the heat that comes from the earth’s center. Read up on geothermal energy pros and cons if you want to learn more

The climate crisis is rapidly getting worse. We need to act as fast as possible to be able to sustain the earth the way it is today for future generations.

Solar panels give us so much hope for a future with less pollution. As fuel sources in the Middle East continue to dry up and as the cost of fuel continues to rise, more governments and investors are looking seriously at the alternative energy sources available to us.

Along with wind energy, solar energy continues to be one of the top areas of development.

Right now, there are several countries ahead of the United States when it comes to creating solar power. Germany currently leads the way in solar powered development with somewhere in the neighborhood of 17,000 megawatts of solar capacity. In contrast, the largest project in the United States is currently still under development out in the Mojave Desert of Calfornia. It is slated to be a whopping 1300 megawatts when complete.

Making solar power profitable is one of the biggest challenges. Right now, electricity typically sells for about 25 cents per Kilowatt. Solar panels cost about $7 per watt of electrical capacity to install on a house. That means it will take many years of operating before a solar panel plant begins to pay for itself and turn a profit. So many years, in fact, that often the solar panels are completely exhausted by the time they have paid for themselves.

Because of this cost, we are likely to continue to see the two extremes of solar energy Either we will see extremely large plants where the economies of size can have the upper hand on the otherwise exorbitant production costs. Or else, we will see solar panels used in small applications where their small size allows them to be easily transported to remote locations.

Several people have even begun using solar panels to power their cell phones and laptops to give them increased mobility, as well as the peace of mind that they can get power wherever they are. When shopping for the best solar cell phone charger you want to read the reviews of people who have used them, as well as choose a company that has a long track record.

It may be awhile before we see solar power take a front seat in world energy. Until then, we can find little ways to use the sun to make our lives better.

Change, hope, faith….

Words that presidential campaigns use to ride the wave of victory. What are these words, if not backed behind the people that believe them. We are headed down a path of destruction of our environment, of our future children and of ourselves. As a world we need to begin to take the next step to a better tomorrow.

What?

The green revolution.

Making tomorrow cleaner then today, is the goal so our planet will remain beautiful and perhaps even regain some of its past glory. The truth is that we as a race have been selfish. We take what we please from wherever we please with complete disregard for the consequences of our actions. Sure, a lot of the problems we caused were strictly naivety, but if that was just simply true, then why have we not corrected some of these actions ourselves?

What steps have we already taken?

Reduce, Reuse, Recycle – this mantra has began the reusing of materials to create new items. It is a step in the right direction, however it is needed on a much higher scale. Meaning that everyone anywhere should be responsible.

Researching alternative sources of energies. There are many alternative sources of energy as you can see in advantages and disadvantages of renewable energy. The greater in-depth our research the faster these renewable energies will become viable. I suggest doing some of your own research into what are solar panels.

We have also began efforts in keeping our streets clean as well as regulations on emissions from factories and vehicles.

Whats needed?

We need to step up all of our efforts, and when we do this world will be better for it. Energy friendly appliances and conserving water, gas and any unclean energy we conserve and do not use unless we have to.

I hope my faith in renewable energies causes change.
Solar panels are a great way to help improve your home and a good start for green living.

Setting up Solar Power for Homes can be quite a challenge and costly, there are many considerations to be factored in, detailed designs to draw, and consultations to be made to ensure that the right systems are installed and that ensure you get as much power in your house without spending too much money, time and effort.

However, most people today do not like discovering new things and exploring new alternatives because of over-reliance on the ‘system’. Here are some of the top benefits on why you need to make a wise decision today and invest in solar power for homes as your solution to power problems.

a) Solar power for homes are reliable and very cheap to maintain. This is primarily because solar panels have no moving parts and the only thing you will need to do is occasional cleaning and dusting and checking that all the wires are still in place. Once you have installed solar power for homes, you will not incur any additional costs such as repairs, if the systems are properly protected from human and animal interference.

b) One of the most important advantages of solar power for homes is that it is environmentally friendly, emit no carbon footprints and will not damage the environment that we live in. What could be better than knowing you are playing a part in ensuring that our children and their children that come in the future will find a cleaner and conserved environment?

c) Solar energy is a renewable source of energy, there is no time you can say the sun is dimmer because you are trapping lots of solar power for homes energy. You also need not worry about the sun every running out of its power because it is a star that has enough hydrogen to burn for billions of years to come. Solar energy is very reliable for use at home.

d) Enjoy flexibility and freedom even if you are living in a remote place or any environment you desire where it is not covered by the power mains. You can choose to install the power from the grid system just as a backup but if you install the right solar power for homes systems, you will not have to worry about running out of power. Of all the options of power to use at home, this is the most practical system to go for.

e) If you generate more solar power for homes than you need, do you know that you can sell the excess power to the power mains? This is a great opportunity for you to generate some income without having to worry about tedious work, the only thing you need is capital and do the installation of the system and you are set.

f) Solar power for homes have no stresses and no demanding maintenance on your part once installed. You will only need to clean the solar power panels and the storage batteries, you can kiss goodbye to hefty monthly electricity bills forever if you install solar power for homes.

If you are exploring options with Solar energy for homes, you might look into passive and active heat systems. You also may wish to check out electrical generators. Active and passive heating systems utilize heat from sunlight and transfer the heat to various parts of homes. Generators provide a free source of electricity for houses. Here are some of the options that you may wish to explore.

Active and Passive Heating

Passive solar heating systems are very simple in nature. For example, opening a window to let the sun in, can be a for of passive heating. This system can also be used to keep homes cooler, if incorporated into the landscape and structure design. Many homes are built with a great deal of southern exposure, to provide passive heating.

An active heat system utilizes a pump to provide heated water. Water is pumped into a collecting station, where the sun heats it. Heated water is then pumped to a form of radiant heat, that can be used in many houses. This system usually works best in warm climates.

You may see a lot of solar swimming pools with active heat systems. The pool pump pumps water to a collector, where it is heated. It is then placed into the water system of the pool. This system can save a great deal of the costs of standard pool heating methods, as their heat source is unlimited.

Passive heat systems can be very effective for heating hot water. They work in the same basic way that active pool heating systems work, except they do not utilize a pump. In order for this to work, they employ gravity, by being placed high above the plumbing system, on the roof.

Solar Generators

Solar generators can be simple or they can be complex in nature. Most of the time, these systems are used as a supplemental form of electricity for homes. It may not be cost effective to have systems that generate all of the power, although this can be done. These systems use a series of panels that make electricity from sunlight.

There is a wide selection of panel systems to choose from. The more efficient ones, tend to be more expensive, but they can be very effective. If you contact a solar energy professional in your area, he can provide a great deal of answers to your questions. You also can get an accurate estimation for installation costs.

Installation costs may be preventing some homeowners from installing these systems. However,
alternative energy systems can be an excellent investment in the future. If you plan to stay at your house for several years, you can recoup the investment, and enjoy free power.

Final Thoughts

When considering Solar energy for homes , you may wish to check into passive or active heating systems. The main difference between passive and active systems, is a pump for water. These systems are good for heating swimming pools and hot water systems. You may wish to have an alternative source of electricity, by installing solar panels on your roof. The costs may seem high, but once the initial investment is recouped, you may enjoy free alternative energy.

If you’ve considered installing a photovoltaic solar power system in the past then you’re likely familiar with the ratio for the return on investment that typically applies.

If you happen to live somewhere that is reliably sunny most of the time then the figures pan out quite well in favor of installing solar panels. If however you live, let’s say North Europe, where there is reduced daylight during the winter months and even the summer months don’t guarantee plentiful unobscured sunlight, then the amount you get back means that the payback period can exceed forty years.

This is not only too long for most people to wait, but the panels themselves typically claim a useful life span of only twenty years or so. However, a Feed In Tariff can change all this quite dramatically. Put simply this ensures that you get paid a heavily subsidized rate for electricity that your solar panels generate. This is often much more than the price you would normally have to pay for electricity, so it suddenly changes the game to favor solar power in even normally unpromising circumstances.

The UK currently operate a scheme whereby you get paid well over four times the normal price of electricity just to generate it. In other words you earn very good money from your solar panels even if you keep all the electricity for yourself. If you do send some back to the main grid, then you get even more via an additional Export Tariff that ensures you get paid almost five times the going rate!

At this level of subsidy you can expect to generate revenues of about £1,500 GBP annually from a 4 kilowatt solar power installation, which means that you can now completely recoup the investment costs in roughly ten years and thereafter you’re coining it for as long as your panels last. The UK government are currently offering to support this scheme (including index linking the payments) for twenty five years, which would give anyone installing solar power now a profit of over £20,000 GBP.

A great deal for anyone who is able to invest in this scheme, but not so great for everyone else because the underlying fact is that solar power is still not able to stand on its own feet economically in northern latitudes, and hence ordinary consumers will simply pay for the subsidy with higher energy costs.

Residential Solar Power makes it possible to become independent from the grid. It is also a way of reducing the cost of electric bills. When we talk about electricity from the sun for home use, what comes into mind are photovoltaic cells and solar water heaters. While the heater is not a producer of electricity, the savings it creates by using sunlight to heat water can be substantial

A lot of us are getting used to photovoltaic panels mounted on rooftops especially in areas that get a lot of sunshine. Photovoltaic energy is becoming popular because there is already a lot of consciousness regarding the environmental effects on the conventional generation of electricity. Coal is the biggest type of fuel for most electric plants but the technology is highly pollutive.

It can be very expensive to connect to the grid in remote areas. In this setting it makes a lot of sense to invest in residential solar power. In cities and other places where the grid is accessible, the cost of generation using sunlight is more expensive than buying electricity from the grid. However we should take note that using sunlight as a means of generating electricity is becoming less expensive each day.

The silicon wafer is the heart of most residential photovoltaic power systems. These wafer are made in such a way to maximize the Photovoltaic Effect. Because each silicon cell only produces a small amount of direct current electricity, they have to be assembled in banks. For a solar power system to work, it requires two other components. The first one is the storage medium and the other is the inverter.

The purpose of the storage medium is to make electricity available especially at night. The most common type of storage device is the rechargeable battery. The storage battery only stores direct current electricity.

The other component is responsible for converting DC into a form that is usable by most home appliances. That component’s name is the inverter. An inverter is also a transformer because household appliances commonly work on 110 volts. The voltage stored in the battery is brought up to 110 volts.

A recent development in electric grid technology is the grid-tied system. When you are a producer of electricity you have the option of connecting to the grid. The other users of the grid will use some of the electricity you generated. At night, you get electricity from the grid instead of storage batteries. The best thing about this system is that if you make more electricity than what you consume, the grid will pay you for the surplus. Now that is great news.

While it is true that solar power is not new technology, it sort of stagnated because there was no economic incentive for it. For a long time coal and oil powered plants were so cheap to operate. Now with increasing cell efficiency and economies of scale, the difference in cost of producing your own electricity versus buying it from the grid is getting smaller. Now, isn’t it time you go solar?

The passive house is a home that provides thermal comfort without the use of “conventional” heating, ie the boiler and radiators, or similar systems. The energy needed to balance the heat of the building is typically provided with non-conventional systems (residential solar power or heat pump to heat the air of the energy recovery controlled ventilation).

The conventional heating system can be eliminated if the energy needed inside the house is very low, conventionally less than 5 kWh per square foot per year. These benefits are obtained with a very careful design, especially with regard to the sun, with the adoption of high-performance thermal insulation on outside walls, roof and glass walls and through the adoption of controlled ventilation systems for energy recovery and with solar panel installation.

Passive house has only three criteria:

• a frugal annual heating – cooling allowance of 4,733 BTU (British thermal unit, a traditional unit of energy equal to about 1,055 joules) per square foot
• an annual cap on primary energy of 11,1 kilowatt hours per square foot for all energy needs including heating and cooling, along with water heating, appliances, and other devices
• the building must be essentially airtight with 0.6 air changes per hour at 50 pascals of pressure.

Each benchmark is many times lower than the targets set by current U.S. energy codes and guidelines.

Passive houses are born in Sweden and are used mainly in Germany, Austria and the Netherlands and in other northern European countries. The first certified passive house project in the Unites States was actually an educational building. Completed in 2006 the BioHaus was designed by architect Stephen Tanner for the Concordia Language Villages campus in Bemidji, Minnesota.

The cost to build or get built a passive house made of wood can vary enormously. It depends on the type of construction required, the quality of materials and assembly. It depends also if you choice environmentally friendly products like Residential Solar Power.

Solar powered attic fans are increasing in popularity. However not many people are familiar about its features. So through this article I hope to share with you some general information about the features of this device that is generally known as solar attic fans. Typically these products are mounted on rooftops and designed to remove humidity and moisture from the attics of homes and buildings. This helps keep the home or building cooler during the summer months and reduce the cost of air conditioning. Thus the main advantage of these device is savings in energy costs and providing a more comfortable atmosphere within attics specifically, and homes in general.

Normally these fans are installed in the highest part of the roof. They have galvanized steel housing with steel flashing. This steel flashing prevents water from seeping in and also helps protect roofing shingles. Overall its installation is designed to look neat and fit well.

There is not much fixing or configuring involved when installing them. They work instantly when the solar panel is attached. The solar panel is not that big and don’t take much space. The size of the panel may vary but no bigger than a panel for a water fountain or garden feature. There is no additional wiring required with most devices you buy, just like a plug and play kind of consumer electronics device. Prices of solar powered attic fans vary from around $200 to $400 depending on the size and wattage. Good brands to checkout when buying them are Honeywell, Rand, and Sunrise Solar.

There are several ways to fix a solar powered attic fan. One way is to use a roof vent and mount the device on the flat top of the vent, on a pitched angle. But the more common way is to mount the frame and flashing flush directly on the roof. Both these ways are good as they don’t attract much attention than a vent for the heating system.
