Solar Roofing Possibilities: The Difference between Solar Panels, Shingles, and Tiles
Share on Twitter | Email To Friend | Posted by Renee in Green Remodeling.
There are several reasons why you might be interested in harvesting solar power. It could be the reduced amount on your electricity bill. Or a belief in clean, non-polluting energy. Or the government rebate. Or the fact that the money you spend on equipment may come back to you in savings within 5 to 7 years. The list goes on. Whatever your reasons, you’ve now got a decision to make. Solar roofing has come a long way since 1954, when the solar panel was invented. Here are some of the differences between the traditional panel and the fancy newcomers: shingles and tiles.
Solar Roof Panels
- Photovoltaic devices are housed in metal frames, which are mounted to the roof. This requires puncturing the roof to bolt the technology down.
- Are frequently shaded by upper roof tiles, reducing sun exposure.
- Reliable and time-tested.
- Utilizes the same silicon-based PV technology as shingles and tiles.
- Typical installation cost is around $8,500, comparable to that of shingles and tiles. To get more details on pricing ranges, contact a certified solar contractor for a free estimate.
Solar Roof Shingles
- Take the place of the original, asphalt tile, and can be stapled directly into the roofing cloth.
- Are an average of 12” wide and 86” long, with an exposed area of 5 inches when stacked.
- Take less space and can be positioned for optimal sun exposure.
- Flexible control over placement, number of shingles, and desired power range/cost.
- Average power output is 50 watts.
- High aesthetic quality for homeowners because they can be mistaken for traditional shingles.
- Installation costs starting at around $10 per watt and go up from there.
Solar Roof Tiles
- Uses interlocking technology to attach to existing tiles without roof penetration.
- Has a seamless look that fits into the shape of the roof.
- Individual tiles can be removed without disturbing surrounding material.
- Adds a layer of protective insulation against UV rays and weather damage.
- Weigh about 2.5 lbs per square foot.
- Typically blue in color.
- Durable and easy to maintain.
- Similar to shingles, average power output is 50 watts.
Now that you’ve benefited from a basic comparison, go to the makers with your questions, or call a certified solar contractor. Solar roofing technology is available through companies such as Atlantis Energy, Uni-Solar, LEED Pro, Sharp Electronics, Sun Electronics, PowerLight, and General Electric.
