NOTICE FOR SOLAR PV INSTALLATIONS

Hessequa Municipality is encouraging the installation of private Small-Scale Embedded Generation (SSEG) systems, particularly Rooftop Photovoltaic (PV) systems.

Homes or businesses that have on-site renewable energy generation will benefit from lower electricity costs and will be contributing to a more secure and sustainable future. Solar PV technology converts energy from the sun to electricity, which can be used in buildings of all sizes. Investment in installing a PV system is posing a strong case due to it leading to reduced costs, especially when electricity tariffs increase.

WHAT IS A SOLAR PV SYSTEM?

Solar photovoltaic (PV) systems, or solar power systems, are renewable energy systems that convert sunlight into electricity. The electricity it generates can be stored in batteries, used directly, or fed back into the electricity grid. Solar PV works well for a wide range of residential, industrial, commercial, and agricultural uses and is considered clean energy, as no fossil fuel is used in generating the electricity.

CONNECTING WITHOUT APPROVAL IS ILLEGAL AND DANGEROUS

Illegally connected systems can compromise the safety of your family, municipal staff and the electricity grid. All new and existing PV Systems must be authorised by Hessequa Municipality.

Poorly installed roof top PV systems and illegal grid connections are a safety concern for the following reasons:

➡️The household may be exposed to the risk of electrical fires and electric shock.

➡️The safety and the power quality of the electricity grid may be compromised by connections that use the wrong equipment or by adding unplanned generation capacity to a part of the network not designed to carry it.

➡️The safety of electricity staff working on the reticulation network could be compromised by the electricity feeding into the grid from illegally connected PV installations.

BEFORE APPROVING THE DESIGN AND PURCHASING OF A SYSTEM

Before installing a PV system, it makes economic sense to first become more electricity efficient. By doing so, you will reduce the size and cost of the PV system you need. Consider installing an efficient water heater (solar water heater or heat pump), installing efficient lighting and switching to gas for cooking and heating.

OBTAIN WRITTEN AUTHORISATION

Obtain written authorisation from Hessequa Municipality if you are planning to install a grid tied system. You will find all the necessary documentation under the Tab “Small-Scale Embedded Generation (SSEG)” at https://www.hessequa.gov.za/document-library/

Do not proceed with installation until written authorisation has been granted. Stand-alone/Off grid systems must be registered with the Municipality but are not required to go through the full authorisation process. Backup generators must also be registered with the Municipality.

OBTAIN A STRUCTURAL ASSESSMENT

Generally, roofs can withstand the weight and wind load of PV panels. However, it is advisable to obtain a structural assessment of the roof, to determine whether it can withstand these loads. Structural engineers can provide this service.

NO NEED TO SUBMIT BUILDING PLANS

There is no need to submit building plans to the Hessequa Municipality for PV systems – unless the panels protrude more than 600 mm above the highest point of the roof, or they are raised more than 1.5 m above any point on the roof, or if ground mounted, the panels in their installed position project more than 2,1 metres above the natural/finished ground level.

BUY THE CORRECT INVERTER

If you are planning to install a grid tied system, be sure to use an approved inverter. Hessequa Municipality uses the same guidelines as of the City of Cape Town. You can find the list of approved inverters at http://www.capetown.gov.za/SolarPV under “Reference Documents”.

CHECK PV PANEL STANDARDS

At the very least, ensure that the PV panels you will use have a Certificate of Compliance for the IEC standard: EC 61215 − Crystalline silicon terrestrial PV modules. IEC standards are the international version of the SABS and are a good indication of panel quality. Ask your service provider for proof.

STORE BATTERIES SAFELY

If you are installing batteries, make sure that they are stored in a properly racked, well ventilated, dry room and in accordance with the Occupational Health and Safety (OHS) Act, Act 85 of 1993. There are compulsory wiring standards for general electrical installations provided in SANS 10142 that cater for electrical installations and a COC should be available on request of the municipality.

For quality installations, make use of an installer accredited by SAPVIA who can issue a Green Card for your installation. See www.pvgreencard.co.za

PLEASE NOTE:

The Electricity Unit of Hessequa Municipality will be conducting inspections on an ongoing basis. All systems not registered will be identified and notices will be issued for compliance and thereafter disconnections will follow.
