Go green and save money on your electricity bill!

The Grape Solar 500 Watt Grid-Tied PV Kit can generate between 30kWh and 70kWh of electricity per month. This amount of power is equivalent to the energy consumption of a 15 Cu Ft refrigerator. The kit consists of Grape Solar GS-S-250-Fab5 Mono-Si modules, Enphase micro inverters and a roof-top racking system for mounting the modules.
This easy to install kit is designed with future expansion in mind. Start small, and generate a fraction of your power consumption, or upgrade and make the power company pay you. You can easily create a larger PV system by adding more kits at any time. Additional kits are easily connected to one another. Unlike other generators, there are no mechanical moving components in the Grape Solar 500Watt Grid-Tied Kit; therefore, maintenance is virtually non-existent. This kit may qualify for 30% Fed tax credit and local incentive programs.

Note: Contact your local electric utility to benefit from rebates and incentives and to ensure that the PV kit is interconnected to meet safety and reliability standards. Professional Installation by Licensed Electrician or Solar Installer is highly recommended and/or required in some areas. Be sure to check local zoning codes and home owner associations prior to purchasing. Contact Grape Solar for recommended installers near you.

Monitoring for microinverter systems is required in some states including California and Oregon. Please contact Grape Solar at costcocustomorders@grapesolar.com or 1-877-264-1014 for pricing on monitoring devices.
