Short answer
Show which Licensed Electrical Worker (and class) commissions your systems and that a Qualified Person handles design approvals, with a link to EMA's ELISE search. Use a short form (property type, roof, monthly bill, postal code), and quote savings only with sources such as EMA's payback ranges.
Who does what on a solar installation (per EMA)
EMA's solar implementation guide describes two regulated roles. Your website should make clear who fills each one, because buyers and building managers will ask.
| Role | Who qualifies | What EMA says they do |
|---|---|---|
| Qualified Person (QP) | Registered architect (Board of Architects) or professional engineer (PEB) with a practising certificate | Ensures design and installation comply with regulations; may obtain BCA, URA and SCDF approvals |
| Licensed Electrical Worker (LEW) | EMA-licensed electrician, electrical technician or electrical engineer | Turns on the PV system, applies for the required electrical licences, assesses connection requirements |
| Generation licence (large systems) | System owner | For 1 MWac and above, may need a Generation Licence and Energy Market Company registration |
EMA notes that solar vendors typically include the QP as part of their service. EMA's licensed electrical workers page sets out the three LEW classes: electricians (up to 45 kVA, 1,000 V and below), electrical technicians (up to 150 kVA design, 500 kVA operation) and electrical engineers (no load limit, subject to licence conditions).
How to show licences on your website
EMA tells consumers to check an LEW's licence card and to search licensed workers on its ELISE portal. Make that check easy, so it builds trust instead of creating doubt.
Licence and credentials section
Avoid showing a full licence card image with the person's NRIC number; the licence number and name are enough for a check. Our guide on licence display for electricians and plumbers covers the general rules for trade websites.
A quote form that collects the right roof and bill details
A useful solar enquiry form lets you size a system before a site visit, without asking for things you don't need yet.
| Field | Why you need it | Keep it light |
|---|---|---|
| Property type | Landed, shophouse, factory, commercial | Drop-down |
| Roof type | EMA lists concrete, metal and tile roofs as common | Drop-down with 'not sure' |
| Approximate roof area or photo upload | Rough sizing | Optional |
| Average monthly electricity bill (S$) or kWh | Estimate system size and savings | A range is fine |
| Postal code | Site visit planning and shading checks | No full address yet |
| Name, phone, email | Follow-up | Consent tick for contact |
Don't ask for an NRIC number, the full electricity bill PDF or SP account number on the first form. You can collect those later, when you prepare the application. Under the PDPA, collect only what you need for the stated purpose and tell people what you will use it for.
Savings and payback claims: only with a source
Savings claims are what most solar sites get wrong. A specific promise ('save 70% on your bill') that a customer can't reach is a misleading claim. Use published figures and say what they depend on.
EMA's evaluating solar PV page gives figures you can cite:
- Upfront cost for rooftop PV of about S$1,000 to S$1,600 per kWp, with smaller systems costing more per kWp (around S$1,660 per kWp for a 10 kWp residential system).
- Annual operation and maintenance of about 1 to 2% of system cost for residential systems, with maintenance every six to twelve months.
- Average residential payback of about 7 years, and around 4 to 5 years for higher-consumption users with larger systems.
- A levelised cost of electricity for small rooftop systems of about S$0.11 to S$0.15 per kWh.
Link to the source next to the figure, add 'estimates depend on roof, shading and usage', and show your own worked example as an illustration, not a guarantee. EMA's payment schemes page explains how exported electricity is paid: SP Group customers can use the Simplified Credit Treatment scheme, while contestable consumers under 10 MWac use the Enhanced Central Intermediary Scheme at wholesale prices.
Pages a solar installer website needs
Beyond the home page, these pages answer what buyers check before they enquire.
How it works: from site visit to switch-on
Site check, system design by the QP, approvals where needed, installation, LEW commissioning, SP Group registration for export.
Licences and credentials
LEW and QP details, ELISE link, company details.
Costs and payback, with sources
EMA's published ranges, your typical system sizes, what is and isn't included.
Ownership options
EMA describes direct ownership and solar leasing models; explain which you offer.
Maintenance and monitoring
Cleaning and inspection intervals, monitoring, response times.
Quote form and contact
The short form above, plus WhatsApp and phone.
EMA also points buyers to the National Solar Repository directory of installers. If you are listed there, link to your listing.
Do it yourself or get help?
A site builder template can cover these pages if you have the LEW and QP details, your own project photos and a clear process to describe. The parts to get right are the savings wording with sources and a quote form that doesn't over-collect personal data. Our website cost guide shows typical prices in Singapore.
Our Business Website (S$1,490) builds up to 6 pages, for example Home, How it works, Credentials, Costs and payback, FAQ and Contact, with a contact form and WhatsApp button, on-page SEO and a site you can edit yourself. You provide the licence details, photos and figures; we lay them out with the sources linked.
Frequently asked questions
EMA's solar implementation guide says a Licensed Electrical Worker is responsible for turning on the solar PV system and applying for the required electrical licences, and a Qualified Person ensures the design and installation comply with regulations. Larger systems of 1 MWac and above may also need a Generation Licence. Check EMA and GoBusiness for the licences that apply to your projects.
EMA says consumers can search licensed electrical workers on its e-Licence Information Services (ELISE) portal and should check the worker's licence card, which shows a photo, name and licence number. Put the LEW's name, class and licence number on your website and link to ELISE so customers can verify it themselves.
EMA's evaluating solar PV page says residential payback averages about 7 years, and around 4 to 5 years for higher consumption with larger systems. Quote these as EMA figures with a link, add that results depend on roof, shading and usage, and avoid guaranteed percentages that a customer might not achieve.
Property type, roof type, a rough roof size or photo, average monthly electricity bill or usage, postal code and contact details with a consent tick. Leave NRIC numbers, full bills and account numbers for later, when you actually prepare the application, so you only collect personal data you need at each step.
EMA's payment schemes page says SP Group customers can register for the Simplified Credit Treatment scheme, paid at the regulated tariff minus grid charges and credited to the bill. Contestable consumers with under 10 MWac can use the Enhanced Central Intermediary Scheme at wholesale prices. Larger systems register directly with the Energy Market Company.
