http://RoofMill.net – Over 10 years ago the founder of RoofMill.net was working on hybrid wind and solar powered homes. Many, years ago the lessons were learned first hand that a solar panel system, or a wind turbine system, was really only able to do 1/2 the job.
The founder of RoofMill.net was the first to start selling a complete wind and solar kit. The invention of the RoofMill™ was key to succeeding. This invention won a earth day 2010 award for “Best New Product” The inventor was pioneering the first Rooftop hybrid home systems in the US and developed all the best of class innovations used today all over the world.
Wind and solar Kits are ideal because peak operating times for wind and solar systems occur at different times of the day and year. This is why hybrid systems are more likely to produce power when you its required. A wind and solar Kit will power a home or business in a much more consistent way than just wind, or just solar alone.
Solar home owners worldwide are now wishing they had gotten a hybrid wind and solar kit when they installed. These customers are now wanting to add wind to their solar only systems. Without any wind powert, they have no electricity in storms, winter, at night, cloudy etcetera. The sun only shines a few hours a day.
Renewable energy experts all concur, a small “hybrid” wind and solar kit. A home electric system combining home wind electric and home solar electric (photovoltaic or PV) technologies offers several advantages over either solar or wind only system. In many areas of North America wind speeds are low in the summer when the sun shines brightest and longest. Wind power is strong in the winter when less sunlight is available. Because the peak operating times for wind and solar systems occur at different times of the day and year, hybrid systems are more likely to produce power when you need it. If you are looking for wind and solar power systems, off grid solar wind hybrid system, wind turbine solar panels hybrid system, hybrid solar wind power generation system, wind solar hybrid system price, solar and wind hybrid power systems ppt, wind solar hybrid system suppliers, solar wind hybrid system project report, wind and solar kits,wind and solar website, wind and solar charge controller, wind and solar youtube, or wind and solar coupons, wind and solar ebay then go to our website at:

Many wind and solar kits systems are stand-alone systems, which operate “off-grid” — not connected to an electricity distribution system. An engine generator can also reduce the size of the other components needed for the system. For the times when your wind and solar kit system is producing, most hybrid systems provide power through batteries and/or an engine generator powered by conventional fuels, such as diesel. If the batteries run low, the engine generator can provide power and recharge the batteries.
Battery banks are typically sized to supply the electric load for one to three days. Adding an engine generator makes the system more complex, but modern electronic controllers can operate these systems automatically.Keep in mind that the storage capacity must be large enough to supply electrical needs during non-charging periods.

what is solar panel?
how can i buy?
how much we required ?
