Are you looking for a quick and uncomplicated solar panel energy project for your house that you can do by yourself?  Putting in a solar attic fan may be just the ticket.  Not only is it fairly easy to do, but it will keep your residence cooler in hot summer days and nights.

You may not have even realized how much a sweltering attic contributes to your air conditioning costs.  Attics trap and retain all of the hot air that rises in your house.  This is good in the winter, but it can inhibit your house from cooling off throughout the summer.

Attic temperatures can easily climb above 120 degrees Fahrenheit even when outside temperatures are only in the eighties or nineties.  Most building codes necessitate attics to be vented, but these vents are simply not intended to cool off the entire attic.  And a roof that has no shade gets sun for the majority of the day.

Installing a traditional attic fan would require a licensed electrician because it would need to be connected to a power source in order to operate.  But solar attic fans are constructed with built-in pv modules powerful enough to run the fans.  Not only are they quieter than electric attic fans, but they require no electricity to run since they are installed on the roof and receive direct sunlight.  

If you are handy with a saw, drill and screwdriver, and self-confident enough to cut a hole in your roof, you can install a solar attic fan in a couple of hours.  You will have to to locate a place on your roof that receives sunlight the whole day, is in the vicinity of the peak and also close to the middle of the attic space.  You will be cutting a hole through the composition shingles and roof decking that will accommodate the size or your solar fan.

The trickiest and most crucial part will be finding the optimal site and cutting the hole the proper size for the fan.  A location that faces south will receive the most sunlight.  If that is not feasible, you can consider buying a model that has a solar module that can be tilted and positioned to face south.  

Once the hole has been cut, it is only a matter of securing the solar attic fan to the roof, and caulking around the fan to waterproof your installation.  You will be able to right away experience the cooling effects in your attic.  And you will be able to enjoy a more comfortable house and lower cooling bills throughout the summer.

Solar powered pool heaters are one of the simplest solar heating applications to put in.  And they are additionally one of the least costly.  So if you are considering installing a solar heater for your pool, here are some details about how they work to help you decide if they make sense for your pool.

Solar pool heaters are ordinarily less complicated than solar water heating systems for your house.  They in general use the pool’s pump and filter, so you will only have the cost of purchasing and installing the solar collector, piping, a diverter valve and an automatic control.

The control lets you adjust the warmth at the high end of the range to your preference so the pool doesn’t get too warm.  The diverter valve works with the control, either sending water into the solar collector to be warmed, or back into the pool if not heating is needed.

Solar pool heaters use a simple open loop design.  That means that the water flows back and forth between the solar collectors and the pool.  When the pool’s pump is on, chilly water from the pool flows into the solar collectors, is warmed by the sun and the heated water flows back into the pool.  There are no extra moving parts involved.

The least expensive solar collectors can be used year round in warm climates, and are also good for average areas where pools are used during the spring, summer and early fall, when air temperatures are above about 55 degrees Fahrenheit. These solar collectors are not insulated and are made from UV-resistant black plastic.  They heat the water to comfortable temperature, but are not useful for heating pools in colder climates.

For heating pools in cold wintry weather climates, a more expensive solar collector with a glass cover and insulated box is used.  Copper absorbers are used as a substitute of plastic, since it does a superior job of conducting heat.  These solar collectors are capable of heating water to the much higher temperatures needed in cold climates.  They are more expensive and more complex to build and install than the lower temperature designs.

But no matter whether your pool is located in a warm, moderate or cold climate, a solar pool heater will save you funds.  Since there are so few components to purchase and install, they usually pay for themselves in energy savings in about 2 years.  And they are very low maintenance, since there are no moving parts.  They are one of the most cost-effective solar applications that can be installed in a home.

Solar hot water heating systems are a basically straightforward design.  Solar collectors reheat water all through the day, which is stored in an insulated reservoir to keep it warm for ongoing use.  But sub-zero temperatures can bring this kind of system to a standstill.  But new and improved methods have been developed that allow solar hot water systems to operate effectively even in cold climates.  Here is a basic description of how they work.

After a few decades of experimentation with solar hot water systems, most qualified users have determined that the closed loop design is the most successful for climates with freezing temperatures.   Because oxygen is eliminated from the system, pumps will not corrode and will have a greater lifespan, saving you time and money for upkeep and replacement parts.

The system is filled with an antifreeze blend (propylene glycol) at the time it is installed.  It then circulates between the solar collectors (where it is heated by the sun all through the day) and the storage tanks, which provide heat during the day and night.  There are several smaller components that allow the antifreeze to expand and contract, and which inhibit too much pressure from building up in the system, among other things.  But the solar collectors, the pump and the tank with heat exchanger are the principal components.

Drainback systems are so named because the solar collectors drain when they are not being used.  Due to this, you can use either water or antifreeze in the system.  But for maximum guarantee that the system will not freeze, people often choose to use antifreeze as an extra precaution, particularly in regions that frequently experience temperatures below zero.  

A thermosiphon system also uses a detached solar collector, along with the pull of gravity. And it allows for the use of an insulated storage tank for more dependable hot water delivery. When using any of these systems in cold regions where freezing is an issue, both the piping and the storage tank ought to be placed indoors and suitably insulated to provide hot water even on the coldest days.

Even though the collectors drain when not in use, they drainback system is still a closed loop system. It requires a robust pump in order to return the drained liquid to the solar collector after it has been drained.  But it is a fine choice for a homeowner who needs a solar heating system that is uncomplicated to maintain.

Solar hot water heating systems are relatively simple to install, easy to maintain and the most cost effective way to introduce your home to solar energy.  They can save considerable energy and cost when they replace an electric hot water heater.  And they can be successfully used even if you live in a climate where freezing temperatures are common during the winter.
