Know what you are choosing
Panels produce DC electricity; an inverter converts it into AC electricity for your home. Optional optimisers can help with panel-level operation where suitable. We explain the selected models, quantities, layout and any optional battery or equipment changes in your proposal.
Product and performance warranties follow the selected manufacturer’s terms. Your agreement separately identifies workmanship items such as mounting, installation wiring and connections, with the actual duration, exclusions and claims process. Maintenance inspections and panel cleaning are listed separately—not assumed to be included.
Review your proposal, sign your Sales Agreement and access signed copies. View milestone invoices, upload the required electricity bill or retailer letter, and follow the progress updates and documents shared by your project team. Secure links remain available when needed.
The signed scope and selected equipment determine what is included. Savings, roof suitability, installation dates and authority appointments are confirmed for each property—not guaranteed by this website.
Our residential solar engineering is specifically tailored for Singapore landed homeowners who wish to reduce reliance on grid electricity and insulate their household against rising energy tariffs.
System capacity is determined by available unshaded roof square footage, roof pitch, tile/metal construction, and sun orientation.
Vonx Solar manages all administrative requirements with SP Group and licensed authorities. Our Licensed Electrical Workers (LEW) handle single-line diagrams, turn-in applications, meter installation requests, and regulatory compliance.
Certified electrical schema matching SP Group requirements.
Interconnection approval for export credit eligibility.
Installation of smart meter tracking self-use and grid export.
Yes. Owners of landed residential properties (Bungalows, Semi-Detached, Terraces, and Corner Terraces) with structural roof ownership are generally eligible to install rooftop solar.
Physical roof and electrical installation typically takes 3 to 4 days on site. The full process—including SP Group grid connection approval and LEW submission—takes approximately 4 to 6 weeks from project execution.
Eligible households buying electricity from SP Group under Simplified Credit Treatment (SCT) receive the regulated tariff less grid charges for surplus electricity exported. Retailer customers may use a different arrangement, including ECIS with payments based on prevailing half-hourly wholesale prices.
Solar panels have no moving parts, but performance monitoring, inspections and cleaning where needed help keep the system operating well. The maintenance schedule depends on your roof conditions and agreed scope.
