This solar calculator provides an indicative estimate only and is not a quotation, guarantee, or bill prediction; calculations are based on your inputs and simplified assumptions including estimated solar generation, an assumed self-consumption ratio (for example, 70% self-consumed and 30% exported), and a standard billing period; for Solar ATAP scenarios, any export credit shown is an estimate and may be limited by programme rules and billing constraints (including MAQ and monthly netting/eligibility conditions) and may be valued using an assumed SMP or credit rate that can vary by billing cycle and market conditions; this estimate may exclude or simplify bill components including but not limited to fixed charges, maximum demand charges (where applicable), ICPT/AFA adjustments, retail surcharges, levies, SST, penalties, and other service-related fees; actual savings, bill amounts, and payback period may differ materially due to consumption patterns, site conditions, equipment performance, installation design, approvals, and changes in tariffs or programme terms; buySolar makes no warranties and accepts no responsibility or liability for any loss or decision made based on this calculator, and users should refer to their official TNB bill and obtain a site assessment and formal proposal for accuracy.
