The Power of Solar Panels

Solar panelsSolar Panels are not new, they have been around for over a decade; however, they are now more appealing due to technological advancement and a new push by the government for renewable energy sources. They are one of the best, as well as a major source of alternative energy.

How Do They Work?

Solar panels absorb sunlight (sunrays) and convert it into energy; this is how they work. The solar panels are made up of photovoltaic cells (solar cells), and these cells collect the sun rays.  Obviously, during daylight hours that is when they are hard at work. This energy is then converted into electricity. Basically, these cells function like semiconductors. The energy produced from light photons eliminates the electrons, and then free electrons are used to generate power.  Here is some very good information on how solar panels work.

The benefits of solar panels are many, and include the following:

  • They are a renewable energy
  • Solar panels are an independent and efficient source of electricity
  • Free energy source
  • They are non-polluting
  • They do not cause any harm to the planet or its atmosphere
  • Very low maintenance
  • They can last a lifetime if properly maintained
  • And more

The more cells you have in the solar panel, the more energy you will able to save. Thus, solar panels can generate a lot of electricity, and it is completely dependent on how many solar cells are used in the panel.  The more the better, but also more expensive is.

Solar Pool Heating

Solar pool heating is an excellent way to save money on your utility bill.  Solar pool heaters are installed on the roof of your home or business, and harness the power of the sun to heat your pool during the day.  This can add up to a lot of savings over the course of the year.

Many areas of the country can only utilize their pool three or four months during the year.  However, with solar pool heating you can increase that window to three or four months, so you can have as many as eight months of swimming in your pool.  This really increases the value of your investment, as installing a swimming pool is usually an expensive proposition.  Many pools cost over $40,000 so if you can only use three months a year, then it doesn’t make a lot of sense.

My neighbor in New Smyrna Beach had a pool built several years ago, and just recently installed a solar pool heater.  She said their pool heater was installed by www.solarvolusia.com, and she said they did a very nice job.  She has been very happy with the performance of this green energy investment, and her pool is much more swimmable than before.  She even commented that last summer the pool actually got too warm and they had to turn them off for several days.

Spray Foam Insulation

Along the lines of excellent green energy products, spray foam insulation in your attic is a great way to reduce your monthly power bill.  It is much more effective than traditional insulation, or blown-in cellulose.  It is clearly the most expensive insulation option, but also has by far the biggest savings payoff.

To work effectively, spray foam insulation is sprayed on the underside of your home’s roof deck. You have to achieve a seal so that there is no air transfer in or out of your attic to the outside air.  The following shows how it is installed.

The resulting effect is an attic that is near the temperature of your home’s interior in the summer months, as opposed to being much, much warmer. So in the summer if your indoor air temperature is 78°, your attic temperature might be 140°F with traditional insulation. This difference is what forces your air conditioning to have to work so hard to keep your home full.
