Small Solar Power House System

Short video describing a small solar power electricity system. It consists of twelve 1 amp solar panels (15 watts each for a total of 180 watts of power – per hour). It is used to run all lights (CFL’s), fans, tv’s, and stereos in my solar power house. also the microwave, coffee maker, blender, can opener, sandwich grill, toaster, vacuum, and computer. Run time for lights/fans only is approx 8 hours. Add in vacuuming, microwaving or toaster along with lights, tv and the fans and the run time is reduced to 4-5 hours a day.  Total cost was about $1200 to $1300

Solar Hot Water System Test Home

A three collector, 120 gallon solar hot water system was installed in the solar power house test.  Water in the solar storage tank is heated to 160 degrees using an antifreeze solution which circulates between the solar hot water panels on the roof and a heat exchanger installed inside the storage tank located in the garage. Domestic hot water is delivered at 120 degrees throughout the home summer and winter. Annually, this system generates 16 megawatts of free hot water using only sunlight.

Revolution for Solar Power & Light Emitters

Louise Bailey, a Ph.D. student at the University of Warwick describes her research into nitride semiconductors with real-world solar power light implications. This video introduces examples of semiconductor devices, e.g. mobile phones, solar cells, and light-emitting-diodes, to show the wide field of application and what potential benefits research into nitride semiconductors has for the solar power house and consumers. An explanation of semiconductor energy bands with animations are followed by Louise Bailey demonstrating absorption spectroscopy, including a display of a bright orange indium gallium nitride sample. To conclude the possibilities of using indium-gallium nitride for illumination on Earth and in space, its many advantages, e.g. compact, reliable, relatively inexpensive, and highly efficient, and how nitride semiconductors have the potential to change energy consumption, defence and the environment are discussed.

Solar Powered House – Solar Power Net Metering

This video illustrates the solar power electricity process of Net Metering, where photovoltaic (PV) panels provide energy with any excess kilowatts generated going back into the utility grid for credit on one’s electricity bill. In addition, rebates and/or tax incentives from your state may be available. The illustrated system is in Vermont. In this case, the solar power house is implemented via panels installed on a separate structure–a garage, but can also be installed on the roof of the house itself or as a freestanding array.

Passive Solar Home Heating

Passive solar home heating can provide abundant, clean, free heat by eliminating the need to burn expensive dirty fossil fuels to heat. The lowest-cost way to get started is with a passive solar power house design. All it needs is well-designed, properly-oriented glass. Two of Zero Energy Design® key concepts are: (1) Isolated Solar Gain in a greenhouse / solarium, and (2) a unique Thermal Buffer Zone, which uses free natural convection air flow to move warm air from the sunny greenhouse to the cold opposite side of the building.

U S Solar Power Expected to Soar

According to MIT’s Technology Review, in a few years, the United States is likely to be the world’s largest market for solar power, eclipsing Germany, which has taken the lead as a result of strong government incentives in spite of the relative paucity of sunlight in that country. A number of factors could make growth possible in the United States–especially changes in legislation that give utilities incentives to create large solar farms.

Last year, the U.S. solar industry got off to a slow start but sales rebounded in the second half of the year, largely because of a drop in the prices of solar panels of up to 40 percent, partly caused by an oversupply due to the recession.

This year solar installations could double due to several likely causes, including decreasing prices for solar panels and installation costs, as well as increasing government incentives, which can make solar far more attractive.

Evacuated Tube Solar Hot Water Panel System

This video takes you through the installation of an evacuated tube solar hot water panel system. A solar hot water system is central to having a solar power house because production of domestic hot water is a large part of total home energy consumption.

Solar Home Heating

Heating your solar power house with solar hot water panels. You can buy them, I made my own. 1 square foot of collector heats 1 1/2 U.S. gallons of water 40 degrees farenheit in Pennsylvania, USA in winter. The more collectors you put up the more water volume you can heat. Most people use one of these collectors for domestic hot water, showers, etc. I used mine to heat my house. Of course insulate well first, then see if you can use this. You’ll need to add radiant floor heat system to get heat out of tank. tonyfixit

Installing A Home Solar Power System

Using solar energy in homes used to be rare.  However, today there are many families using solar energy to be environmentally responsible and save money.  Installing a residential solar energy system may seem overwhelming but with help appropriate to your needs you can get the job done.

Solar power house systems are not overly difficult to install.  They are self contained and modular which makes them easy to service as well.  The nature of your homesite and the orientation on your home’s roof to the sun will determine how the solar panels will need to be installed.  It may be necessary to install them near your home with a ground stand rather than mount them on your roof to more effectively collect the sun’s energy.

When installing a home solar energy system you may want to also have a battery storage system to provide power when there is a solar deficit and avoid interruption should a power outage occur.  With one, when all your neighbors have no power your solar power house is running like normal.  Without a battery storage system surplus power is can usually be used to reverse your electricity meter for a reduction on your bill.

Your decision on what type of system will in part be determined by whether you are going to have it installed by a contractor or build it yourself.  Both approaches have different options, and depending on what you want and what works best for your home you will have the choices of what you want to do as far as type.  Depending on the particular circumstances, it is sometimes a good idea to have an independent solar consultant give you recommendations if you do not feel qualified to do your own research.

Regardless of your approach, you will want to take a good look at the appearance and of type of system that seems best for your home.  Consideration should be given to such factors as the elevation of your home for accessibility and they style of your home. 

Installing a residential solar energy system can be done by the homeowner.  However, there are some complexity and safety issues related electricity hook-up and plumbing to consider that may require a  licensed contractor.  However, the labor expense portion of the installation of a qualified solar system will also apply against most government tax incentive programs for solar.
