Mandatory standards
for solar installers in Mauritius
When the solar market opens up, opportunists arrive first. Here are the minimum standards that every prospect should demand - and that every competent authority should impose - to protect Mauritian consumers.
5 installer categories
Each category corresponds to a level of competence, experience and installation capacity. An installer cannot take on a project beyond their category.
| Cat. | Description | Max. capacity | Required experience |
|---|---|---|---|
| A | Category A - Simple residential | up to 10 kWp | 20 documented PV installations |
| B | Category B - Residential + batteries | up to 30 kWp | 50 installations, 10 with storage |
| C | Category C - Commercial | up to 250 kWp | 500 kWp installed, documented |
| D | Category D - Industrial / large rooftops | > 250 kWp | 2 MWp installed + structural engineer |
| E | Category E - Agrivoltaic / special structures | project-dependent | Independent structural report required |
The 3 fundamental pillars
These three requirements form the minimum foundation that every approved installer must meet, regardless of their category.
In Mauritius, given the climate, salt, cyclonic winds and maritime proximity, the design office must not be a commercial option. It must be a minimum obligation for any grid-connected installation.
Minimum requirement
Every approved company must have an in-house design office or a permanent contract with an approved design office.
- Consumption study and PV sizing
- Production calculation and shading study
- Single-line diagram and layout plan
- DC/AC cable and protection calculation
- Cyclonic resistance note and structural loads
- Commissioning and maintenance file
Every installation must be supervised and signed by a qualified engineer. The presence of an engineer is not a luxury - it is a safety guarantee for the client and for the CEB network.
Minimum requirement
A quote without a named signatory engineer is an incomplete quote. Refuse it.
- Electrical engineer (BEng/MEng) for any system > 10 kWp
- Structural engineer for any rooftop installation > 30 kWp
- IEC 62446 certification for commissioning
- Mandatory continuing training every 3 years
- Mandatory signature on plans and diagrams
- Professional liability insurance covering the engineer
Experience is not declared - it is proven. Every approved installer must be able to provide a file of verifiable references, with client contacts and commissioning reports.
Minimum requirement
A simple commercial licence must not be enough. Real experience is the only guarantee of competence.
- Reference files with verifiable client contacts
- Commissioning reports and conformity certificates
- Client attestations and conformity certificates
- Mandatory supervision by senior installer for beginners
- Category upgrade conditional on actual completed work
Red flags - Run if you see these
These signals indicate that an installer does not meet minimum standards. If you see any of them, ask for clarification or change installer.
No design office mentioned in the quote
No signatory engineer identified
Vague or unverifiable references
No structural calculation note for the roof
No professional liability insurance
No ten-year warranty offered
Undeclared subcontracting
No technical file provided before connection
Prospect checklist - 8 questions to ask
Before signing a quote, ask your installer these 8 questions. A serious professional will answer each one without hesitation.
Ask for the installer's approval number
Require the name and qualifications of the responsible engineer
Ask for 3 verifiable references with client contacts
Require a signed structural calculation note
Ask for IEC certifications for modules and inverters
Check professional liability insurance and ten-year warranty
Require the single-line diagram before signing
Ask for the complete file before CEB connection
