Residential Solar Power Systems
Residential Solar Power is an extremely viable solution for home properties. It provides free renewable energy and can act as a backup supply during
Different kinds of systems
There are different kinds of residential solar power systems, designed to suit different situations and different requirements, with variables in set up and the components that are used.
The three main configurations are GRID-TIED, HYBRID and OFF-GRID. Within each of these, there are many variables, which Sunergy Solar configure as a custom installation particular to your site and needs.
Where you rely on the grid for when the panels are not producing, i.e. at night.
Power from the panels is used during the day when they are generating, in priority over grid power. If there is not enough power generating from the solar panels, electricity from the grid is used to subsidise the load required.
Surplus electricity from the panels is not stored, but is directed back into the grid.
Hybrid systems are like the grid-tied system, but with the addition of batteries to store excess energy from your solar system for use in the evenings, with the grid as your backup.
This also allows for some emergency loads to be run in an off-grid way from solar and batteries during a power cut – like your lights and fridge.
Additional components are used to manage power.
An off-grid system has no connection to the electrical grid, and is the sole source of power.
A battery bank and backup generator are used in addition to the solar panels. Surplus electricity generated during the day is stored in the battery bank for use when panels are not generating—ie at night.
Off-grid houses require a more energy conscious design for water heating and space heating and are most common where connecting to the grid is cost prohibitive.

Through saving you money on your power bills, residential solar power systems can quickly pay for themselves and soon even bring an effective return on your setup investment.
Using NIWA’s historical data and today's average power prices, we’re able to give you an expected ROI.
These graphs show your expected return based on a 4.16kW system, saving $0.30c per kWh of grid supply.
The sooner you go solar, the greater the return ~ so why hold off on a good investment?
