One coordinated system for generating, storing and using energy

Commercial solar and battery systems

For a business, a combined system can be designed around daytime generation, evening operations, peak demand, critical loads and future growth. The best outcome depends on how these factors interact, so annual consumption alone is rarely enough to finalise the design.

Our assessment can include:

• electricity bills and interval consumption data
• business hours, production schedules and major loads
• daytime solar self-consumption and existing grid exports
• roof area, orientation, shading and access
• switchboard, metering and connection capacity
• peak demand and time-of-use tariffs
• battery charge and discharge requirements
• outage exposure and selected backup loads
• network, planning and fire-safety requirements
• future equipment, EV charging or site expansion
• eligibility for current solar and battery incentives

This produces a system recommendation with a defined operating strategy. You should understand what the system is intended to do, which assumptions the proposal uses and which variables may change the outcome.

Residential solar and battery systems

For a home, coordinated design can balance daytime generation with evening and overnight demand. It can also account for air conditioning, electric hot water, pool equipment, an electric vehicle, working from home or selected backup circuits.

The right combination is property-specific. A large solar array does not automatically justify a large battery, and a battery should not be sized from a rebate threshold or headline capacity alone. We consider usable generation, load timing, backup expectations and future plans together.

If you are considering generation without storage, see our solar panel installation service. If solar is already installed, our battery storage service explains the retrofit pathway.

Why install solar and battery together?

Coordinate equipment from day one

Planning both technologies together makes it possible to choose a compatible architecture, allocate installation space, plan cable routes and define monitoring before work begins.

Match generation to storage

The solar array and battery can be sized around the same consumption data and operating goal, reducing the risk of disconnected decisions.

Plan backup correctly

Where backup is required, the essential circuits, power demand, changeover equipment and expected duration can be considered as part of the initial electrical design.

Reduce avoidable rework

A coordinated project may avoid revisiting switchboard, metering, communications or approval decisions that could have been addressed in the first design.

Assess incentives as one project

Some current programs treat combined solar and battery projects differently from battery-only installations. Eligibility still depends on the customer, equipment, capacity, timing and program rules.

Our solar and battery process

1. 01
   Define the objective — We establish what matters: reducing grid purchases, making better use of daytime generation, managing business peaks, supporting selected loads during outages, preparing for new equipment or a combination of goals.
2. 02
   Collect the right information — You provide the address, bills, interval data where available, property and roof details, operating hours, major loads, timeframe and supporting photos. We identify any additional information needed before design.
3. 03
   Assess the site and electrical system — We review roof conditions, solar layout, battery location, switchboard, metering, cable routes, access, network requirements and backup needs. A site inspection may be required to confirm the concept.
4. 04
   Design generation and storage together — We prepare a coordinated recommendation covering solar capacity, battery capacity and output, inverters, controls, monitoring, backup scope, equipment and relevant enabling works.
5. 05
   Confirm approvals and eligibility — Network, planning and incentive requirements are checked for the specific project. Any discount shown must be supported by the applicable delivery pathway and current rules.
6. 06
   Install, commission and hand over — The system is installed and commissioned as one project. We configure the intended operating modes, establish monitoring and explain how the solar and battery work together.

Current solar and battery support

The Australian Government's Cheaper Home Batteries Program supports eligible small-scale batteries connected to new or existing rooftop solar for households and small businesses. Program settings and certificate values can change, so eligibility and the actual discount must be confirmed when the project is quoted.

In NSW, battery activities may also sit within the broader Peak Demand Reduction Scheme. These programs have different technical rules and customer thresholds. Sunny Renewables assesses the relevant pathway for the proposed system and does not represent an indicative percentage as a guaranteed project discount.

Why Sunny Renewables

Mitch and Dylan formed Sunny Renewables with more than 20 years of combined electrical and solar experience. That experience supports the integrated thinking a combined system requires: solar generation, storage, switchboards, metering, control and the property's wider electrical needs all have to work together.

Our approach is built around:

• one coordinated design for solar, storage and electrical infrastructure
• commercial reasoning grounded in site and energy data
• clear explanations of assumptions, limitations and backup scope
• quality equipment selected for compatibility and application
• planning for future loads, expansion and monitoring
• professional installation, commissioning and communication

We want the proposal to be understandable before the work begins and the system to have a clear job after it is switched on.

Solar and battery installation across Sydney, the Central Coast and Newcastle
