Planetary Systems has been designing and installing renewable energy systems since 1994, and has over 1600 operational systems from 4kw to 22kw, worldwide.  We have always been and remain committed to tested and reliable, yet cutting edge technologies to advance local power generation capabilities.  We firmly believe all electrical power should be locally generated and using as much energy as practically feasible from wind, solar, hydro-electric and other renewable sources.  Based on this, our products reflect our experience and expertise in renewable energy, hydronic heating and water supply systems.  A majority of the products and systems available on our website are in everyday use either on our own or nearby off-grid systems and we strive to test and evaluate products prior to making these available in the marketplace.  Planetary Systems offers our own battery technology, integrated power solutions, and the best available products available in the world marketplace.  Our offerings are based on value-added products, not bargain basement prices, and include complete testing, design and integration of systems plus expert technical assistance.  We hope you find this approach valuable and will consider Planetary Systems, Inc. for your grid tied or off-grid renewable energy system, as well as your source for energy saving appliances and services.
