Basic Solar Array Components

Solar Panels

Solar modules are rugged, solid and built to withstand the elements. Since there are no moving parts besides electrons, there is very little maintenance (they might need cleaning once a year or in drought conditions). Our modules have a limited power warranty for 25 years.




Electricity flows from the solar panels to an inverter.  The inverter changes direct current (DC) from the solar panels into alternating current (AC) for everyday appliances and the grid.  Inverters put out pure sine waves that match or even exceed the quality of the frequency coming in from the local utility.  The inverter also has a display that shows lifetime production and environmental benefits.  




Grid Interconnection Equipment

Most grid-tied solar PV systems require two electric meters in the TVA region. One meter is the existing meter which will still track your consumption. The second meter will monitor your solar electricity generation. Every solar kWh will be tracked through your solar meter, and you will be credited 4 cents above the RS and GSA-1 rate for each kilowatt-hour through TVA’s Green Power Providers (currently this totals about $0.15 per kWh).
