and some more info about solar trends
According to a recent study, 80% of over a thousand American respondents think all new home construction from now on should include some sort of solar energy systems. Once informed of the higher resale value that homes with solar systems can have, 2/3 of those surveyed said they'd expect to pay more money for such a home, a would do so willingly; what's more, 1/2 of those surveyed said they'd even be willing to pay a 10% premium on for homes with solar energy systems built-in.
Solar Water Heaters: People living in warm climates and freezing climates alike can now enjoy the benefits of solar water heating. Though the technologies are slightly different depending on whether there's ever a freeze lasting longer than a night or two, solar hot water is a viable option wherever a person may reside.
Solar Shingles: By all appearances, these look like ordinary shingles, but look closer and you'll see that they're actually thin-film solar cells. The amorphous silicon material used in these shingles is reported to be even more effective at collecting sunlight than regular solar panels while still being strong enough to be used as a roofing material. They're installed in an overlapping pattern, just like regular shingles, thus providing the same level of weather protection. The wires run underneath a plywood roof deck that protects the house from the intense heat these solar shingles absorb, and the shingles are held in place by a glue-like EVA compound that is activated by heat.
Recreational Solar Kits: The average Joe and Jane consumer can purchase complete solar kits that come with everything one needs to get solar power up and running in their RV's, weekend/seasonal cabins, and boats. Your typical solar kit will include:
o 1 or more photovoltaic modules (solar panels)
o Mount (such as a flush mount rack or a pole top fix rack)
o Charge controller
o Safety disonnect
o Fuses
o Fuse box and/or circuit breaker
o and in some cases, a storage battery
Solar/Stellar Battery: Russian scientists have developed a battery that captures solar energy itself without the need for an external panel or collector. A true 21st century innovation, it also collects energy from stars, regardless of meteorological conditions.
New Materials: We touched on it in the above section on solar shingles, but thin-film solar cells deserve a repeat mention in any article on current trends in solar polar. This new, silicon-based thin-film technology adheres heat pumps and solar cells onto other surfaces, whether wood, drywall, glass windows, plastic - imagine the possible applications! This technology will vastly increase solar energy's versatility and range of practical applications while vastly decreasing the associated costs. Other promising R&D efforts into newer and better materials for solar energy equipment includes solar cells made from titania nanotubes, natural dyes, lead and cadmium selenide nanocrysals, and everyday plastic.
21% of Venture Capital firms surveyed spent a combined total of $500 million on renewable energy start-ups, including many solar power companies. Nanosolar is a start-up company that uses materials based on nanotechnology to make solar systems more efficient. Energy Innovations is a company that uses mirrors that follow the sun installed on panels to collect solar power.
According to Clean Edge, a company that conducts independent research on clean technologies, reports that the market for solar energy has increased 55% from 2004 to 2005, and will further increase from an $11.2 billion industry to a $51.1 billion one come 2015. By 2015, the costs for grid electric power and solar power should be neck and neck.

Solar Energy Science Projects
Solar energy can be used to heat our homes,
heat water, cook our food, and power our lights.
These science projects will help you learn about solar energy and how it
works. The first three projects focus on different ways to use solar thermal
(or heat) energy. The fourth project focuses on solar electric energy.
Each project is broken into several parts:
Z The purpose of the experiment
Z The materials and equipment you will need to do the experiment
Z Where to find some of the materials
Z How to assemble and conduct the experiment
Z What you may see during the experiment
Z How the specific energy type works.
Some of the experiments may require help from an adult.
To help you understand new terms, we have included a glossary in the
back. We have also included a resource list on the back page with
information on where to get equipment for the experiments. The list also
names places where you can find more information on solar energy.
We hope you learn something from the experiments. But most of all, we
hope you have fun!

MICROCONTROLLER BASED SOLAR PV SYSTEM UPS FOR DOMESTIC APPLICATIONS
ABSTRACT
Uninterruptible Power Supply (UPS) systems are being popular and presently used in commercial, industrial and residential applications. Presently the UPS system has two major classifications, one is on line UPS and another one is off line UPS. In both the types the battery system inside the UPS is charged by the mains AC Supply. A by-pass mode of operation is also incorporated in the UPS during normal supply. This paper presents a novel technology to charge the battery using Renewable Energy Systems (RES) particularly of Solar PV power. Battery charging can mostly be done by the solar power whereas if the PV power is inadequate, then the UPS system i.e. the battery is discarded from the PV panel and automatically connected to EB mains. The inverter in the UPS system can also replaced by controlled Voltage Source Inverter (VSI). A prototype of 1-Ph, 1-kVA UPS system has been examined for the above work. Controlled inverter has been realized by a dedicated PIC 16F877 controller. The output of the inverter has been maintained as 230 V +/- 2% by using PWM technique, which is incorporated in the PIC controller.
