ON GRID SYSTEMS
SITECNO solar energy kit is on-grid PV system, a complete solution which generates electrical energy for self-consumption and feed surplus energy in to the grid as per legislation of the country. Solar PV panels generates DC electric power when exposed in sun light. High efficiency MPPT PV inverter converts DC electric power in to AC electric power for consumption in load. Grid power supply is
connected in parallel circuit with PV inverter AC output. Solar generated electric power has first priority for consumption in load and additional power can be retrieved from the grid supply if required. Solar energy system can be hybrid with diesel generator power for the operation as PV-diesal hybrid system. Solar energy system is useful for saving in electricity bill, saving in diesel fuel consumption and source of income by selling surplus energy to the grid.
1. Instant self-consumption system with feed into the grid
An instant self-consumption system means that consumers have solar system and also connected with grid supply as additional support. During the day, the energy generated by the solar system is consumed, and additional power from the grid.
When the solar system generate more energy than consumption, this surplus energy is injected into the grid according to the legislation. Solar energy will provide the benefit to reduce the electricity bill.
2. Instant self-consumption system without feed into the grid
A self-consumption system without injection into the grid has the same function as the instant self-consumption system, in addition a device Watt-meter to regulate power.
3. Solar hybrid system compatible with diesel generator
Hybrid system with grid supply means consumers consume solar energy and get the additional power from the grid. At the moments there are power failures, power from diesel generator is obtained to maintain the continuous power supply without interruption.
4. Solar hybrid system with batteries compatible with diesel generator
This system is similar to the previous one except that include batteries.
In case of power failure, power consumer will consume either batteries or diesel generator. In this system diesel generator is used to meet energy demand and charge the batteries.
