Bulk Buy vs
Independent Solar & Battery
Solar battery bulk buy – is it right for you?
Solar battery bulk buy offers may appear straightforward, but an independent install can suit your roof, budget and timeline better.
Solar battery bulk buy – how it really stacks up
Even though both options unlock exactly the same federal and state incentives, the experience is very different. The council bulk-buy is a fixed bundle delivered by ShineHub with pre-selected equipment and finance and a standardised sign-up.
The independent route lets you design the system around your own roof, power bills and long term plans – and deal directly with a local technician.
Key points at a glance
-
Bulk‑buy = preset process, limited choice.
-
Independent = full design freedom and direct local service.
-
Either way, you still receive the federal battery discount and NSW battery‑plus‑VPP incentive.
Bulk buy vs independent – money matters
Why can two quotes for the same battery capacity differ so much? Independent pricing excludes programme administration fees, aggregator margins and the extra cost of zero‑up‑front finance baked into most bulk‑buy offers. Always line the figures up after rebates, then add the finance charges to see the real total.
Three‑step cost check
-
Collect the bulk‑buy quote and a local independent quote of the same size.
-
Apply identical incentives (federal discount + NSW VPP payment) to all.
-
Compare the final repayment totals, including any loan or PPA terms.
Independent design – better fit and better aftercare
A one‑size package can be fine for a simple roof, but if you have partial shade, plan to add an EV charger or just want premium panels, a tailored design matters. Independent installers can specify micro‑inverters, optimise battery size and give you direct after‑sales support – no call‑centre queue.
Why custom design helps
-
Fits complex roofs, shading and future load growth.
-
Lets you pick panel brand, inverter type and warranty length.
-
Service and warranty work handled by technicians who know your system.
ShineHub VPP vs your choice of VPP
Joining a Virtual Power Plant (VPP) means your battery can earn payments for helping the grid. The NSW VPP incentive stacks with the federal battery discount, so the financial upside is clear. The difference lies in control: the bulk‑buy enrols you in one fixed VPP contract, while an independent install lets you shop around for the best tariff – or opt out entirely.
Questions to ask before joining any VPP
-
What rate will I be paid per kWh?
-
How often can my battery be dispatched?
-
How long is the contract and are there exit fees?
-
Does participation affect the battery warranty?
