So what is the difference between a home equipped with solar panels vs. one with solar roof tiles? It is not hard to notice. Solar panels are those large, bersome units that often are perched atop the roof of a house, making it look to some people like something out of a science fiction movie.

To install the panels properly, it is often necessary for additional roof framing or roof penetration. And if yours is the first house on the block to install solar panels, you might have to endure lots of funny looks and derogatory comments from the neighbors.

On the other hand, solar roof tiles are much less obtrusive than solar panels. As the name implies, solar roof tiles are incorporated into your existing roof, whether it consists of asphalt shingles or most other common types. One shingle weighs about 2.5 pounds per square foot, so they are generally easy to work with when it comes to installation.

They tend to be a dark bluish-gray in color, so they blend in easily with most existing roof types. And the best thing is that they provide for a seamless look, so the untrained eye will not be able to tell the difference.

But perhaps the best thing about solar roof tiles is how they help you save on your energy bill. One tile puts out about 50 to 200 watts of energy, which is about as much as a small window fan. While this may not sound like much, if you incorporate the tiles into your entire roof, you should be able to supply enough energy for your entire house.
And if you are fortunate enough to live in a sunny state such as California, Florida, or Arizona, you may even produce more energy than you need. You can then sell this excess energy back to the local power company, further reducing your energy costs.
So not only do solar tiles look great, they’ll help you do what’s really important: save money. To find out more about solar tiles visit solar roof shingles.

This is a small 24v DC geared motor I attached to one of our Small Stirling Engines using plumbing fixtures for a mount. This is a NO LOAD TEST. The maximum voltage was 22v DC and the estimate was 300 mA. So this can produce about 6.5 watts with this simple setup. I am working on a more efficient process. Due to the weather, NO LOADS were tested today but I have tested some LEDs and small DC motors with good results. I will expand this test when we get better sunny days. Summers in the Sunshine State are 150 days of clouds:-)

Professional grade solar powered attic fan uses no electricity.

The Sunfan Professional Series – Roof Mount Attic Fan is designed to reduce heat build-up in your attic in the summer and remove harmful moisture in the winter. It’s commercial grade, heavy duty construction provides up to 25% more power than other fans, providing better circulation and improved airflow in your attic space. One fan can ventilate up to 1250 square feet and lowers the attic temperature so your air conditioning won’t have to run so long to cool your home. By running year-round, it can keep your attic space drier by removing moisture in the winter, reducing condensation and preventing the growth of harmful mold and mildew.

Cools in the Summer
During the summer, the Roof Mount Attic Fan vents the hot air out of your attic and keeps it closer to the temperature outside. Your air conditioner won’t have to run so long to cool the inside of your home.

Prevents mold and mildew in the winter
In the winter, warm moist air rises from the inside of your home and collides with the cold underside of the roof. The Roof Mount Attic Fan provides the air circulation that prevents the moist air from condensing on the surface. Keeping your attic drier.

This new power plant has two towers and 24,000 mirrors and produces around 5 megawatts of power, enough to power about 4000 homes in areas near the Lancaster California power plant. ESolar has strong funding from the likes of Google and other large clean-tech focused venture capital firms.

ESolar’s new power plant is small scale, but an excellent demonstration of their technology. The goal of the project (one might say this is the goal of all solar power projects actually) is to produce electricity cheaper than coal. But ESolar seems to have a technology that is impressing people in the know. Already they have contracts to build 465 more megawatts of these solar power towers at three sites in California and New Mexico.
