Financing for a solar or water-heating project is not just about the system size. Monthly repayment and total cost depend on the final scope, deposit amount, lender terms, and whether extra electrical or plumbing work is required after site survey.
What Changes Repayment
Two clients can choose the same package and still receive different financing offers because the financing structure is influenced by project scope and lender decisions.
- Final BoQ value: The financed amount depends on the confirmed project scope, not just the initial estimate range.
- Deposit size: A larger deposit usually reduces the financed balance and monthly repayments.
- Repayment tenure: Longer tenures reduce monthly payments but can increase total cost.
- Lender policy: Approval criteria, fees, and interest structure vary by financing partner.
What to Prepare Before You Ask
You do not need a final quote before discussing financing, but you should prepare enough project and budget information for a realistic conversation.
- Your target outcome (backup uptime, savings, hot water demand, or continuity for a business site).
- Expected budget range and whether you plan to pay a deposit.
- Preferred payment approach (cash, staged payment, or lender financing inquiry).
- Site and load details that affect the final BoQ (roof, DB condition, major loads, plumbing layout).
For technical planning that affects final scope, review System Sizing 101 and DB Split & Essential Loads Planning.
How Iselle Handles It
Iselle starts with a budgetary estimate so you can plan early, then confirms the actual project scope after survey, engineering review, and BoQ preparation.
- Initial pricing conversations are based on plan ranges or calculator inputs.
- Site survey findings are used to confirm the engineering scope and final BoQ.
- Financing discussions happen against the confirmed scope so repayment estimates are more realistic.
- Proposal and handover documentation support clearer internal approvals and record-keeping.
