In the 21st century, solar technology is advancing pretty fast. The latest and greatest invention to show up in the the PV pike is thin-film solar cells. These are made of layered semiconductor materials that are just a few micrometers thick. This thin film technology makes the home's roof shingles, tiles, building facades and window glazing made of photovoltaic material possible. These shingles and glazing are just as secure and strong as the conventional shingles and glazing.
Pros and Cons
Some advantages of considering this technological energy include zero carbon emissions. That means there is no pollution, and no waste. This is probably the cleanest energy you will find anywhere.
The next "pro" is being able to free yourself (at least partially) from big power companies. You won't have to depend on the power grid system, so you won't be at the mercy of rate hikes and power outages.
However, there is a disadvantage of solar panels also. At this point, they are still very expensive. The average cost for a home installation of the typical solar panel system is around $35,000. Many people cannot afford that.
Types of Solar Panel Systems
There are solar thermal systems and the solar electric systems. The solar thermal system is definitely not as costly as the solar electric systems. Solar thermal systems can cost you as little as $8,000, and a nice solar electric system can run you close to $45,000. In some cases you me be able to find rebates for the installation of solar panels.
Another disadvantage of solar electric systems is that they need to be protected from mechanical damage (against hail impact, wind and heavy snow, etc.). This is super important for wafer-based silicon cells which are very brittle.
A third disadvantage is that some people think they look unappealing up on the roof.
But if you’ve got some money to invest in something that will eventually pay for itself and you’re interested in reducing your impact on the environment, solar may be the way to go.
