Solar panel refers either to a photovoltaics(PV) moduleor to a set of solar photovoltaics modules electrically connected and mounted on a supporting structure. A   PV module is a packaged, connected assembly of solar cells. Solar panels can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. Most solar modules are currentlyproduced from solar cells made of polycrystalline and monocrystalline silicon.

ON-GRID INVERTERgrid-tie inverter is a power inverter that converts direct current (DC) electricity into alternating current (AC) with an ability to synchronize to interface with a utility line. Its applications are converting DC sources such as solar panels or small wind turbines into AC for tying with the grid





OFF-GRID INVERTEROff-grid or Stand-alone inverters, used in isolated systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Many stand-alone inverters also incorporate integral battery chargers to replenish the battery from an AC source, when available. Normally these do not interface in any way with the utility grid, and as such, are not required to have anti-islanding protection





HYBRID INVERTERThis is possible through a technique that adds different energy sources (phase coupling: on-grid or grid-tie techniques) and the management of stored electricity in the battery (off grid technology). Hybrid inverters therefore operate on grid (grid-tie) as well as off-grid, hybrid (both on-grid and off-grid at the same time) and Backup (in case of a black out).





MICRO INVERTERSolar micro-inverter is an inverter designed to operate with a single PV module. The micro-inverter converts the direct current output from each panel in to alternating current. Its design allows parallel connection of multiple, independent units in a modular way.

Micro-inverter advantages reside mostly on single panel power optimization, independent operation of each panel, plug-and play installation, improved installation and fire safety, minimized costs with system design and stock minimization.



backup battery provides power to a system when the primary source of power is unavailable. Backup batteries range from small single cells to retain clock time and date in computers, up to large battery room facilities that power uninterruptible power supply systems for large data centers. Small backup batteries may be primary cells; rechargeable backup batteries are kept charged by the prime power supply.



variable-frequency drivevariable-frequency drive (VFD) (also termed adjustable-frequency drivevariable-speed driveAC drivemicro drive orinverter drive) is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed andtorque by varying motor input frequency and voltage
