GT02 Grid-Tied Solar Street Light Power System

A grid tied solar street or parking lot light is a light that is connected to the power grid, but also has a solar array and grid-interactive inverters. The solar array on the top of the light becomes a power generator, delivering electricity into the grid during the day, thereby offsetting the power used by the lighting at night. Grid-tied street lights will work just about anywhere in the United States. With the top five states having the fastest return on investment and the best solar policies being: Massachusetts, New Jersey, Rhode Island, Oregon, and New York. Though each state offers a different mix of policy and incentives, all these states have managed to ensure a future in which solar power is a big part of the energy picture. These five states are setting the standard for what it means to be solar-friendly. That’s not to say that a grid-tied solar parking lot like isn’t a viable opportunity for investment in other states. When the abundance of sunlight is combined with utility incentives, state and federal tax credits, and low power LED lights; the result is a solar powered light that can operate with nearly zero energy costs.

A grid-tie solar street light system includes a solar panel combined with a grid-tie inverter and a couple of other electrical system components to create electricity that is then fed to the main electrical grid. A typical system includes the following components: Solar Panels, Inverter, Inverter Wiring, and the AC disconnect. Systems can be supplied to operate on 240V split-phase or 208V three-phase (one inverter per phase). A typical kit includes all essential components to facilitate solar power generation in a safe manor. Additional parts for the AC connection like conduit, AC electrical wiring, AC junction box, back-feed breaker, etc. may need to be purchased separately. A bidirectional meter will also be necessary, we suggest contacting your electric service provider for additional information about meters.

Please Note: This product is a special order and is non-returnable except in the event of a fault (during its warranty period) when the product, once returned will be repaired or replaced.

 

The solar panel must be installed in a location where it can receive full direct sunshine (when available) and usually set facing South at an appropriate angle (where adjustment options allow). The solar panel must not be installed in a shaded or part shaded location and never indoors. The standard specifications of the system (particularly the solar panel Wattage and battery capacity) may need to be adjusted. These components are determined by your geographic location and power consumption. Such changes to the standard specifications may increase or decrease the cost shown. Please contact us for more information or assistance. System performance is subject to various factors including (but not limited to) geographic location, seasons, temperature, weather conditions, location of product, etc. Performance of most solar systems can reduce during winter months when the weather is poor and the days are shorter. During this time insolation hours decrease accordingly. Variations in system perforance due to one or more of the above factors does not define the product as being ‘defective’ or ‘not as described’. Although unlikely, we reserve the right to supply this product with any minor alterations or minor changes to the specifications (shown above by text description or by photographs) due to different supplies or product batches received, incorporating such product changes made by the manufacturer, without further notice. Descriptions, specifications and photographs are updated regularly but may not be current when minor changes to a product have only recently been made.

The product specifications above should be used as a general guide. We can offer modifications and changes to the specifications of this product if necessary. This may be required to meet your specific needs and/or due to the geographic location of the installation site. In locations where insolation levels are poor or lower than normal, a higher wattage solar panel and larger capacity batteries may be required. We offer full product customization and options including UL listed or ETL certified components and the provision of Buy American Act (BAA & ARRA) compliance, if required. Please contact our sales department for more information before making your purchase.
