Are you using more power during night? Sydney Solar Tech will provide solution for you. That is Hybrid solar system. Hybrid system comes with a battery storage to store your excess generation of your solar system and you can utilize this stored power when you want later during peak time or nighttime.

Hybrid solar systems are the best of both worlds: you get the guaranteed (well, 99.9% of the time) electricity supply of the grid, with the ability to store your excess solar energy for use when the sun isn’t shining. This typically reduces your dependence on grid imports by 70% to 95%.

Hybrid systems are also at least half the price of an off-grid system and do not require diesel backup.
The only difference between a hybrid solar power system and a regular grid-connect system is the addition of batteries and a battery inverter
