CONSIDERATIONS
LEGAL REQUIREMENTS
NERSA (National Energy Regulator of South Africa), as well as safety requirements by local authorities, makes it compulsory to register all PV installations. All grid-tied systems have to be designed and approved by a Registered Engineer. A grid-tie PV installation may not be a nett supplier of electricity into the grid – in other words you are not allowed to generate more than what you consume.
APPROVAL PROCESS
For grid-tied systems (including hybrid systems), the property owner must submit an application to the relevant authorities for approval. Design diagrams, signed off by a Registered Engineer, has to be included in this application. Installation of a PV system can only start once this approval has been given by the relevant authority. On completion of the installation, it needs to be signed off again by a Registered Engineer and, together with a COC, submitted to the relevant authority for approval to connect the PV installation to the grid. MrSola does all this daunting administration work for our Clients at no cost once you commit to proceed with the installation.
INSTALLATION PROCESS
MrSola uses specialised rigging teams to install solar panels on roofs. We believe that care should be taken that the extra load factor of solar panels and mounting frames does not compromise the roof structure. MrSola uses “Green Star” certified electricians for solar PV installations. The normal duration of a residential installation will be 2 days. Installation time for agricultural and commercial projects vary according to the size and location of the project.
BATTERY BACK-UP TECHNOLOGY
MrSola backs technology and therefore we only install Lithium-Ion Batteries. Li-ion batteries, although more expensive in initial purchase cost, have the following benefits over lead-acid batteries:
– Significantly lower life cycle cost compared to conventional lead-acid batteries.
– Much longer productive battery life with the ability of deeper cycling.
– Li-ion batteries are safer and do not require special, well-ventilated areas.
– Li-ion batteries are much more space and weight-efficient. – Quick charge times ensure that rolling Phase 5 load shedding can be handled.
