This is the Sustainable Technology Center of the San Juan Islands, which was put together by Planetary Systems, Pacific Custom Homes (James Sackett) and Ward Phillips back in 1994-1995. This was the first commercial sustainable project utilizing all the concepts which have now become standard fare…Grid-tied RE systems, low energy heating and water systems, on-site waste-water treatment and low energy lighting. Here the main office building is under construction in the spring of 1995. The project had a renewable energy system utilizing (3) PV tracking mounts connected to the central control system which was state-of-the-art at the time designed by Planetary Systems. You may have seen this photo in many forms used by others in renewable erergy publications, however Planetary Systems did design and install this entire system with the help of Guard Electric on San Juan Island.   The battery bank was (2) parallel strings of IBE industrial 2vdc cells in a sealed and fan-vented enclosure. These batteries were the best available at the time (1995)     The power system consisted of (2) Trace SW-4024 inverters with grid-tie setup which feed all the renewable energy outlets and systems, thruought the complex. The renewable energy power was dedicated to prioity lighting, heating and specific outlets located in all offices to provide continuous power during outages and to offload this power from the utility source.   This project utilized an onsite water recycling unit which allowed waste water to be cleaned and re-cycleed thru the system to flush toilets, saving a lot of fresh water. The pressure tank with the X on it was designated as non-potable water.   The project and systems were very successful, allowing this complex to use 80% less services than comparable buildings, but also brought to light the complexities of dealing with regulatory agencies which generally are not on-board with such advanced systems and who do not like change unless they can control it. In recent years these agencies have become a little...

This is our latest grid-tied system with energy storage featuring our new PP-Ultra Power Package using Outback Power Systems components. These systems are more efficient at producing, storing and utilizing energy than any system currently available. A 2kw PV array can provide almost all the power for this home and can provide back up power for days during an outage. This system is located in Bellevue, WA a short distance from our System-1 project. Power Package The Power Package system with battery modules is located in the back of the garage as noted. The system includes 5kw of AC Outback GTFX-2524 (2) power inverters, an MX-60 controller and 1200 amp-hours of AGM battery capacity.   Power panels The local electrician (Trinity Electric) simply added an additional AC panel next to the original panel and transfered all priority loads to this panel (fridge, lights, heating) so that when power is out, the power is instantly connected to the Power Package system. When power is available, all power generated by the solar panels is diverted to the house load or selling back power to the utility   Reduced array size With the PP-Ultra power system utilizing battery storage and Outback POwer System components, a roof full of solar panels is not required to offset the house load or provide meaningfull utility billing reduction due to the significant effect of energy storage. Using AGM battery storage, a 2kw array can provide the same effect as a much larger (3-6kw) array using non-battery based technology for the same overall price, plus the benefit of backup...

An example of a small cabin system for a local summertime cabin using our Power Package model PP-2524/3K-17 system. A 2500 watt system provides enough power for a micro-wave, TV, fridge and other small appliances inluding a DC water pump. The Power Package system was installed in the ajacent shop and connected to a new PV installation which is pole mounted behind the shop.   The PV array was combined with an existing set of Pv modules and increased from 320 to 720 watts. This about the smallest array recommended. The pole mount sets behind the shop on a hill to get maximum...

A small cabin in the highlands above Livingston, Montana. This system includes our Power Package system, solar panels and a well pump system for summer use. The system maintains itself during the winter and can be started up by turning on the water system. A small backup generator provides power on cloudy days when being used. Power Package The Power Package system, our model PP-2524T/5K-15AGM, is located in the basement area and provides 120/240vac power just like on the grid.   Batteries Our exclusive VRLA/AGM battery bank is located next to the Power Package in a container to keep out rodents. These batteries need no maintenance or venting   Solar panels A 600 watt solar array is located next to the cabin, pole mounted to be adjustable. The system can accomodate another complete set of panels and a wind generator or two for...

This home near the Seattle metro area is probably one of the most energy efficient homes in the area. The home has our Power Package PV grid tie system, 98% efficient radiant heating and a solar hot water system with backup instantaneous gas water heaters. PV power system The home has a 2.4kw PV array on the roof mounted on a flat roofing system with a tilt to optimize the summer sun while taking advantage of winter sun also   Solar hot water The roof also supports a 20 tube, evacuated tube type solar hot water manifold.     Power Package In the basement mechanical room, our model PP-3648GV/7K-21AGM Power Package is connected to a main utility panel and an load panel to provide power to the home for several days should utiility power be interrupted as it was in 2007. The battery system has 52 kilowatts of power storage using sealed, maintenance free AGM type batteries.   Radiant heating The photo shows the radiant heating system using a Buderus GB-142, 98% efficient gas boiler with two Rinnai instantaneous hot water heaters and a Buderus ST-300 solar hot water tank to the far...
