Going solar<h2 class="sectHeading">Safer, faster solar PV approval</h2><p> <strong>In an effort to make SSEG approvals faster and safer, from 1 October 2023 all SSEG applications to the City will be treated as grid-tied systems.</strong> </p><p>This means that all systems need a City-approved inverter and professional sign off.  <br><br>Currently, many systems using non-approved inverters are not correctly wired, posing risks to the safety and integrity of the network and significantly slowing down the registration process. An approved inverter means quicker authorisation.</p><h4>The following do not require authorisation:<br></h4><ul><li>Solar Water Heaters (thermal) </li><li>Solar security/garden lights </li><li>Portable UPS trolley inverters (that you plug into the wall socket)</li></ul> <h2 class="sectHeading">Solar water heating options for the home<br></h2><p>Switching to a more efficient water heating system will help you save money on your electricity bill.</p><h4>Solar water heaters</h4><p>Solar water heaters are a set of pipes that are placed on the roof of your home. Heat from the sun warms water that can then be used throughout your home for all your hot water needs.</p><h4>Heat pumps</h4><p>​​​​​​​Heat pumps use a small amount of electricity to power a pump. The pump acts as an air conditioner in reverse, moving heat from the air into the hot water geyser.</p><p>Heat pumps are a good option for homes and flats that do not get a lot of direct sunshine or do not have enough space or the right construction to support a solar water heater.</p><h4>Solar PV water heaters</h4><p>Solar photovoltaic (PV) water heaters use PV panels to generate electricity from the sun to heat water via an electrical element. The water can then be used throughout your home for all your hot water needs.</p><h2 class="sectHeading">​​​​​​​​​​On-site electricity generation</h2> <span> <div class="notification with-heading dark-copy pink bg-light-grey"><div class="graphic with-border"> <i class="info toptip">​​​</i> </div><div class="desc"><h4>Solar PV Installer Newsflash<br></h4><p>If you are a Solar PV Installer, and would like to receive more information on Small-scale Embedded Generation (SSEG) from the City, you can <a href="" target="_blank">subscribe to our Solar PV Installer Newsflash</a> to stay up-to-date with the latest information.</p></div></div></span> <h4> Solar Photovoltaic (PV): Embedded Generation (EG)</h4><p>Solar PV technology converts energy from the sun to electricity, which can be used in buildings of all sizes. Investing in solar PV can help reduce the amount of electricity that is bought from the City.</p><p>Solar PV is one form of Small-Scale Embedded Generation (SSEG). SSEG refers to systems generating less than 1MVA that are connected to the City's electricity grid. EG refers to systems with a generation capacity of more than 1 MVA and less than 100 MVA.</p><p>Solar PV is suitable for any place where there is a good solar resource and electricity is already used including residential, commercial and industrial areas. </p><p>All solar PV systems installed within the City of Cape Town electricity supply area must be <a href="">registered for authorisation</a>.<br></p> <span> <div class="notification with-heading dark-copy pink bg-light-grey"><div class="graphic with-border"> <i class="info note">​​​</i> </div><div class="desc"><h4>Find out more<br></h4><p>Guidelines for <a href="" target="_blank">safe and legal rooftop solar PV installations in Cape Town</a>.</p></div></div></span><span> <h2 class="sectHeading">​​​​​​​​​​Choosing a solar PV system​​​​​​​</h2></span> <p>There are a number of solar PV configurations:</p><h4>Grid-tied systems​​​​​​​<br></h4><p>These are connected to the City's electricity grid either directly or through your property's internal wiring. There are two types of grid-tied systems.</p><ul><li> <strong>Grid-tied feed-in </strong> <strong>system </strong>(also known as an EG with export option): the electricity generated by the PV system is used on the property. Excess electricity generated from the system is fed back into the electricity grid - you may receive credit from the City.</li><li> <strong>Grid-</strong><strong>tied non-feed-in PV </strong>(also known as an EG with no export option, with reverse power flow blocking): the electricity generated by the PV system is used on the property only when there is a demand for it. Excess electricity generated is blocked from feeding back into the grid.</li></ul><h4>​​​​​​​​​​Grid-tied hybrid systems</h4><p>Grid-tied systems that island after interruption of the distributor supply or when the applicable electrical service conditions are outside stated limits or out of required tolerances and then supplies the load from the inverter, operating in the stored-energy mode via a suitably interlocked change-over switch.</p> <span> <div class="notification with-heading dark-copy pink bg-light-grey"><div class="graphic with-border"> <i class="info note">​​​</i> </div><div class="desc"><h4>Please note</h4><p> From October 2023, off-grid or standalone SSEG systems and ​​​​​​​passive standy UPS utilised as standby hybrid systems (see below) will <strong style="text-decoration:underline;">no longer be authorised</strong> due to the risks they pose and the time required to approve.<br></p></div></div></span> <h4>Off-grid or standalone SSEG systems​​​​​​​<br></h4><p>These systems have no connection to the grid. They are physically separated and electrically isolated from the grid. An example would be connecting a pool pump directly to a solar PV system instead of connecting it to the building's wiring. </p><p>Off-grid systems must also be registered with the City to ensure they are not mistaken for grid-tied systems. See the <a href="" target="_blank">Rooftop Solar PV Guidelines for Safe and Legal Installations in Cape Town</a> for more information about different kinds of PV systems.</p><h4>Passive standy UPS utilised as standby hybrid system</h4><p>Applies to any UPS operation according to the following principle: </p><ul><li>The normal mode of operation consists of supplying the load from the grid</li><li>When the grid is outside stated limits, the load is supplied from the UPS inverter, operating in stored energy mode</li></ul><p>Such a system will only be regarded as standby provided that it is equipped with a suitably interlocked change-over switch.</p> <span> <div class="notification with-heading dark-copy light-blue bg-light-grey"><div class="graphic with-border"> <i class="info fastfact">​​</i></div><div class="desc"><h4>Find out more​</h4><p>Our <a href="" target="_blank">Load-shedding Resilience Guide </a>offers easy and affordable ways to protect your home from load-shedding.
