The City of Cape Town Says It is often Approached for Guidance as to How to Choose the Right System and Installer.
1. Grid-tied solar pv system:
2. Grid-Tied Hybrid Solar PV System:
TheSe Grid-Tied Systems Are Able to Disconnect The Incoming Electricity Supply and Connect The Essential Load to the Pv System or Stored Energy in Batteries.
3. Standby Solar Pv System (Interconnected with Electric Installation)
VERIFY:
Ask if the solar Pv Service Provider Has Substantial Prior Experience in Solar Pv Installations, with References.
ESTABLISH WHETHER the Solar PV Service Provider Designed, support and installed the systems or only carric
Request Proof of Electrical Certificates of Compliance (COCS) and/OR Professional Engineer Sign-Offs on Previous Installations.
Ask for proof of previous installations that have ben city-authorise.
Ensure that the inverter proposed is on the city ’s approved increter list.
Find out if the installer is registered with sapvia and the electrical contractors board (ECB) -T ’s not compulsory But Shows Commission to Industry Best Practice.
Be Energy-Wise to Reduce System Costs:
Before Installing a solar PV System, Become More Electricity-EFFICient to Reduce the size and this count of the system repired
Systems Must be safe and legal:
Installers Must Apply to the City to Authorise The System for Grid Connection to Ensure the Safety of the Electrical Network, Your Home and All WORK On the Electrical Grids.
If City Staff and Contractors do Not Know About Systems Connect to the Grid, They Run the Risk of Electrical.
Regardless of the type of solar Pv System Being Installed, Authorization Must be Obtained in Writ.
No City-Charged Authorisk Fee:
An Installer May Charge a Fee for the Professional Services Rendered to Perform the Autility on the Customer ’s Behalf.
Get a structure engineering assessment:
MAKE SURE ROAN WITHSTAND The Weight and Winding Load of Solar Panels WHERE NECESSARY.
Building Plans Not Required for PV Systems:
Unless The Panels Protrude More than 600 Millimetres ABove the Highest Point of the Roof;
Ory are raised more than 1.5 metres any point on the roof;
OR If Group-Moundted, The Panels in their Installed Position PROJECT More than 2.1 Metres Above the Nature/Finished Ground Level.
Buy The Correct Inverter:
You can find the list of approved inverters here.
Check Solar PV Panel Standards:
At the very least, get a certified of compliance with the sans/IEC Standards:
Sans/IEC 61215: 2015 -Crystalline Silicon Terrestric PV Modules.
Sans/IEC 61646: 2016 – Thin Film Terrestric PV Modules
Store Batteries Safly:
In a Properly Racked, DRY, Well-Ventilated Room.
Ensure Specialised Circuit Breakers Are used:
The DC Current from the PV Panels Requires Specialised Circuit Breakers.
Get all available warranties and manuals:
For the installation as a whole and for its components (Solar Modules, INVERTERS, Structural System).
Recourse for poor work:
An independent inspection of the installation may be requested.
In Cape Town, An Organisation that carries out this work is the electrical appspect into the source of sound,
BEFORE it can carry an Photovoltaic dc circuit breaker inspect, it must be provided with the class of compliance of compliance and the customer Next to pay an inspection fee.
