First LADWP Approved and Funded PV Installation 3/3/2001   GO Solar Company installs the first grid-tied solar electric system in Los Angeles to qualify for the LA Department of Water and Power's solar energy incentive program. This solar installation on Valley Heart Drive in the San Fernando Valley is helping to create, one of the most energy efficient homes in Los Angeles. This home is also equipped with other energy saving devices and appliances, including a new high efficiency air conditioner, solar hot water heating system along with its new 1 kw solar electric system. Nick Ray's - Solar Home in Sherman Oaks Energy Savings Before solar this home's average electric consumption is 14 kwh's a day. The solar power supplied to the house is 1 kw multiplied by the hours of sunlight daily. On an annual basis the system will generate 5 kwh's a day. The solar will supply over one third of this home's power usage. The electric meter spins backwards when the sun is shining. Installation of Solar Panels The solar panels were installed on the carport roof, a location that remains directly accessible to the sun all day. Avoiding shade is critical to overall system performance. Spacing between panels allow unobstructed access for firemen and hoses in the event of a house fire, with a wood roof. Mounting the panels Siemens solar panel mounts proved to be well engineered, sturdy and aesthetically pleasing. All mounts are fastened through the roof into rafters with stainless steel lag bolts. The solar panel arrays consists of 16 panels in groups of 4, wired in series to produce 80 volts of DC power. Neat - clean engineered mounting system Installation of DC to AC Solar Inverter This system included a 1 kw Advanced Energy Systems inverter. The inverter was secured to a carport wall that is not exposed to direct sunlight and inclement weather conditions. Keeping the inverter cool will help increase power output during long hot sunny days. The long summer days are when this system will be supplying many kwh's of power into the electric grid. An added benefit is the solar electricity generated helps reduce the peak hour demands on the electric grid. The DC solar electricity comes down from the roof, into the inverter, where it is inverted into 120 volt AC power. The solar panels are wired to supply 80 volts of DC power to the inverter. This power is then efficiently changed into usable household 120 volt AC power. The AC power from the inverter, feeds the home's main electrical panel. The AC conduit on this system goes through the carport wall, into the garage where it continues up and across the ceiling and across a 65 foot attic. This high quality inverter is rated at 93% efficient and includes AC and DC disconnects as well as internal fused connections for as many as 6 groups of solar panels. The inverter is relatively lightweight and easy to install. The GC1000 inverter is rated for outdoor use and does not require an optional weather protection hood. If the utility grid drops out, this inverter will shut down in less than 2 seconds as a safety measure to protect anyone working on the power lines. Advanced Energy Systems GC1000 Inverter Testing and checking inverter voltage Safety Safety is the highest priority on our installations. GO Solar's experience allows for a safe working environment on every job The solar panels are solidly fastened to the roof and can withstand wind speeds well over 100 mph. All necessary disconnects, fusing, grounding and lightning protection were installed to allow for a code compliant installation. All installation manuals and component information are provided to the homeowner.
