• Electrical Meters for Solar PV Projects
    Ensure you have the correct meter for your site One of the areas often overlooked when doing a site inspection for Grid-Tied installations is the type of electrical meter and its compatibility with Solar PV Installations. It is essential to ensure that the meter used for a grid-tied PV installation is suitable and compatible with the equipment being installed. Below we have listed some of the more popular types of meters available in the market and which have varying levels of suitability:1. Electrical Meters suitable for Solar PV Installations including power export: Smart Meters These are well suited to solar installations because they can pick up exported energy and separate it on a customer’s electrical bill. In the Johannesburg City Power region, the only meter that is currently pre-programmable for bi-directional application is Itron. All other meters will need to be replaced for installations. Find out more here. In the City of Cape Town municipality, the Landis & Gyr 4-quadrant meter is used. Find out more here. In other areas, installers should contact the local municipality to check what options are available. 2. Electrical Meters suitable for Solar PV Installations but not power export: Certain Prepaid Electrical Meters These are not suited to exporting power as they pick up power exported as power imported, resulting in a charge of any power that has been exported. Inverter-specific export limiting solutions to consider are the Solis with built-in export limitation, Goodwe meter, SMA Sunny Home Manager, and SolarEdge solutions. Alternatively, a Solar-Log export limiter can be used with certain inverter types to prevent feeding back. Some older prepaid meters (see section 3 below) may trip when export limitation devices are used as they have not been designed to consider the reaction time for the device to limit the power to zero in the event that power generated exceeds power consumed by the property. In some areas, municipalities will swap out these older meters, and installers are advised to check this in advance.Electrical Meter but not Smart Although these are suitable and will work, these units also pick up exported power as an additional charge on the homeowner’s electrical bill, similar to prepaid meters. This option may not be legal in all municipal areas, and exporting may trip the meter which would require it to be reset. 3. Electrical Meters not suitable for Solar Installations: Old Mechanical Meters These are not suited to solar applications as they are not designed to spin backwards and may not be calibrated to do this, although they have been used for installations in the past. In some areas, municipalities are actively swapping these meters out and replacing with prepaid meters. Any meters fitted with an internal earth-leakage No grid tie inverter should be installed after an earth-leakage as it causes nuisance tripping and may trip when the inverter synchs to the grid.Ecolec Meters These meters are fitted with an internal earth-leakage that ...

  • Huawei Smart I-V Curve Diagnosis Reduces Project Risk
    Reduce the technical risk of your PV investment Fault identification through Huawei’s certified Smart I-V Curve diagnostic tools offers a low cost, highly efficient method to identify faulty PV modules in projectsThe highest technical risk involved in PV investment is early-life failure & long-term failure of PV panels. In fact, a TUV investigation showed that among 12GW of solar PV plants, 30% (3.6GW) had severe defects, and 50% (1.8GW) of them resulted from panel issues. Early-life failure is mainly caused by quality problems, while long-term failure typically results from panel decay. In both cases, this can lead to heavily reduced power output, lower yields, and thus lower returns. It can be difficult to identify faulty panels in a PV plant. Existing methods are very costly, inefficient, take considerable time and resources, and usually consider just a proportion of all PV strings. By contrast, the Smart I-V Curve Solution by Huawei identifies faults through data mining, and by using algorithms of pattern recognition. Using the Neteco monitoring platform, a command can be sent through the datalogger and on to each inverter to implement IV curve data collection, after which the results are sent back to the Neteco platform for diagnosis analysis and report generation. The time taken to analyse each megawatt of capacity is just 7 minutes from the moment the instruction is issued via Neteco. Results are extremely reliable – in a 60MW plant case study, Huawei’s Smart I-V Curve tool diagnosed faulty panels with 100% accuracy, finding all 141 panel failures. Huawei’s Smart I-V Curve Diagnosis Solution has received TUV Certification, giving assurances to lenders and owners to help aid management of the O&M phase of projects. The Smart I-V Curve Diagnosis option is available for an annual subscription fee which at the time of publishing this article is typically between USD 60-90 per annum (project dependent). Source: Smart I-V Curve Diagnosis SegenSolar Assured Export Limitation packages for Huawei The Huawei Smart Logger can be used to monitor a Huawei inverter or plant and can provide detailed generation and consumption reports. The most recent firmware update of the Smart Logger permits export limitation on Huawei inverters, when used with a suitable compatible meter.

  • Li-ion batteries for Africa
    Li-ion batteries have been commercialised elsewhere in the world. Why not in Africa yet? Large Li-ion battery packs in home and grid-power applications are rapidly becoming more popular in many parts of the world, including AfricaMost of the companies manufacturing Lithium Ion batteries are situated in the USA, Poland, South Korea, Japan and China. Most of them work closely with electric vehicle manufacturers and consumer good products. Some of the top companies manufacturing the batteries include BYD and PylonTech. The University of the Western Cape's Energy Storage Innovation Lab has started work on industrial Li-ion batteries assembly, the only known facility doing this in Africa. Manganese is an important component of the most popular batteries in the world and 80% of the world's known reserves of this element can be found in South Africa. Because the companies that produce Li-on batteries are willing and able to invest significantly for the development of this technology, together with the relatively low cost of Manganese, they have been able to import it from South Africa. So what would be the major challenges in commercialising Li-ion across Africa? The cost of a Li-ion battery system needs to be lower than any alternative energy storage system. Currently, Li-ion batteries cost significantly more than Lead Acid batteries, but since they last much longer than Lead Acid, it makes more financial sense and better return on investment. Because Africa's power distribution network is still underdeveloped, investors in Lithium Ion could see returns sooner than in regions with a fully developed transmission network that's already paid for.

  • Draft IRP 2018 finally released
    SA’s Integrated Resources Plan available for public comment Large allocation to utility-scale renewables and embedded generationThe long-overdue revised Integrated Resource Plan (IRP2018) has now been published and is available for comment. In addition to providing direction to utility-scale projects, the IRP now also includes an allocation for embedded generation for projects between 1MW and 10MW, which has the potential to create opportunities for large commercial solar PV projects. The costs of new-generation technologies have come down, and as Government has recommended the least cost option, this means that renewable energy is favoured in the new plan. A total of 5 670 MW of energy will be derived from PV, and will account for 10% of installed capacity. Interested persons and organisations are invited to submit written comments on the draft IRP within 60 days of publication to the Director-General of the Department of Energy for the attention of Mr Tshepo Madingoane, email address: IRP.Queries@energy.gov.za Source: www.energy.gov.za Choose Huawei for large-scale commercial projects With added focus on embedded generation in the draft IRP, SegenSolar recommends Huawei string inverters for megawatt-scale commercial projects. The Huawei 50KTL inverter is perfectly suited to commercial projects, with 6 MPPTs and 12 strings ensuring highest yields and maximum control. A technical report by TUV Sud has shown that Huawei string inverters outperform central inverters, achieving an additional 2% yield, and an availability of no less than 99.996%. It is therefore no surprise that three-phase string inverter shipments have now overtaken those of central inverters.

  • JinkoSolar’s Net Profit of Q2 Has Seen an Increase of 2653% from Q1
    JinkoSolar’s 2018 Q2 solar module shipments and revenues increased 38.7% sequentially to 2,794MW, mainly driven by continuous demand and new product launches. Gross profit increased 11%, and particularly net profit of Q2 has seen an increase of 2653% from the previous quarter and 109% increase from the second quarter of 2017, as a result of strong global sales network, higher capacity utilization, and industry leading cost structure helped offset the impact from new policies issued by the Chinese government on May 31st. Moving on to 2018 second half and full year guidance, the company has good visibility of order bookings for the entire year which is predominantly comprises of overseas orders and markets which are growing rapidly and will generate significant opportunities ahead. Based on the current business outlook, the company is expected to deliver 6.7GW-7.2GW of solar panels during the second half of the year, representing a 40% sequential increase. On a full year base, the total shipment will reach between 11.5GW – 12GW, increasing >17% YoY, which is very likely to make it secure No.1 position once again in the industry. Moreover, its gross margin and net income is expected to grow significantly in the coming quarters Q3 & Q4 due to continual operational efficiency improvement, diversified customer base, highly competitive products and higher level of R&D activities. JinkoSolar’s CEO commented during Q2 earning call, “We are taking full advantage of our market leader position and production facility in Florida to expand our presence in the U.S. market. Demand in emerging markets continues to grow, especially in Latin American, the Middle East and North Africa. We are deploying our resources there towards securing large & long-term orders through our mature sales network which spans a number of markets. We believe that the Indian solar sector will maintain its long-term growth trajectory despite the short-term impact of recently announced tariffs and we will continue to explore opportunities there.” Regarding the impact of China’s latest policy, from the global perspective, the policy will accelerate grid parity worldwide, and incubate numerous growth drivers for the industry. Even in China, demand from Top Runner Program, poverty alleviation projects, local government subsidies, and self-contained DG projects will continue to drive the growth in the Chinese market, especially in regions with ample sunlight and high commercial power prices. On one hand, it will push the agenda for industrial upgradation and accelerate the industry’s consolidation by phasing out outdated production capacities and replacing them with high efficiency ones; On the other hand, it will also push the rapidly falling cost of solar, making solar more competitive and stimulating the global demand. Grid parity spurred by China’s current policy, will lead to new waves of demand for years to come. Lately, it is observed the demand from emerging market surged, that requires high-performance and better price. JinkoSolar’s advanced technology and production suits it well.

  • The South Africa Photovoltaic Industry Association (SAPVIA) welcomes the long-awaited draft Integrated Resource Plan
    PRESS STATEMENT FOR IMMEDIATE RELEASE 27 August 2018 The South Africa Photovoltaic Industry Association (SAPVIA) welcomes the long-awaited draft Integrated Resource Plan SAPVIA welcomes the long-awaited draft Integrated Resource Plan based on rational energy planning providing a solid foundation to a sustainable future.  This was finally approved by Parliament on the 22nd August 2018.  On the 27th August 2018 the Minister of Energy, Mr. Jeff Radebe released the Plan for public review and commentary.  It is important to note that we are currently in an energy transition and the rational energy plan will be the cornerstone of its success, however the IRP 2018 in its draft format has failed to address the current transition by delaying this to the medium term. SAPVIA, however is grateful to see the least cost energy mix being a crucial component of the revised IRP, especially given the prior consultation the Department of Energy did to develop and solicit input assumptions to the IRP 2018.  Solar PV, wind and natural gas are indeed the cheapest viable energy sources that can be used to power South Africa’s energy demands.  The following elements of the IRP 2018 however cannot go without specific mention and commentary; The Minister made specific mention that the IRP 2018 is published with the understanding of a “just transition’ towards responding to a changing electricity industry landscapes. The just transition should be holistic in nature to factor in all other critical issues faced by the electricity/ power generation industry such as accurate summation of jobs that the industry will generate for ordinary South Africans. The IRP 2018 does not make any specific mention of the round 5 bid window of the IPP procurement initiatives, yet the Minister of Energy through the Department of Energy had promulgated this round of procurement through an official determination. The IRP 2018 makes no specific mention of the Smalls Programme, that was setup and preferred bidders announced.  Clarity on the way forward of these projects needs to be prioritized. The Small-Scale Embedded Generation market in the form of facilities such as rooftop-PV installations and the growth in demand for LPG gas for cooking rightfully deserve a specific mention and quantification.  This is important because the growth of these sectors have spiked significantly over the years and therefore it becomes increasingly important to accurately weigh this growth against the projected electricity demand. We believe that the 200 MW allocation is insufficient to address the growing needs of this market segment. The IRP 2018 made a specific mention of the consistent annual procurement of new additional capacity from various energy sources in the energy mix. However, in terms of Table 7 of the Integrated Resource Plan there seems to be a lag period from 2022- 2025 where the committed Solar PV capacity ends and the new additional capacity will be procured. This lag period of about 3 years doesn’t bolster well for the Solar PV industry and will not do justice to the consistent growth required for the industry to ...

  • The global battle against climate change
    Cut CO2 - Save the Climate South Africa can make a differenceWhile Africa’s contribution to global warming is not nearly as large as developed nations, the sad reality is that our region is suffering from its effects. The results of climate change are being felt across the globe with rising sea levels, tropical storms crunching into shorelines, floods and drought destroying historically-fertile lands, and permafrost in the polar regions melting. Erratic rainfall patterns, lower crop harvests, spiralling food prices and diminishing natural resources are already causing increased human migration, tension and conflict. By the end of this century, it is predicted that over 180 million people in sub-Saharan Africa alone could die as a result of climate change. The time to act is now and South Africa is in the position to lead. Not only does South Africa have some of the best renewable solar resources in the world, being an active member of the African Union and a vocal member of the G77, we can influence the battle against climate change for the entire continent.

  • Access to reliable electricity in Africa
    In Sub-Saharan Africa, only 2 in every 5 people have access to a reliable source of electricity GDP is growing by over 4.5% annually, while generation capacity only grows at a rate of 1.2% Many people do not fully realise the size of Africa. Made up of 54 countries, it’s the same size as China, India, Europe, and the US combined with a total population 1,216 billion. Africa makes up 25% of the world’s population and has the youngest population in the world. In 2015, a British index named Africa as one of the world’s most entrepreneurial places. Comparing the young population’s creative potential with a growth of only 1.9% average seen in advanced economies, it is easy to see why many international businesses have recognised Africa as the future economic growth engine of the world. But, is infrastructure development keeping up? With more than half of the total population without electricity, the basic needs of scholars such as much needed light to study by are not met, while hospitals can’t function effectively and businesses can’t grow to their full potential. In much of sub-Saharan Africa, mobile phones are more common than access to electricity with almost 1 billion cell phone subscriptions. Compare this to the access to reliable electricity and the size of the opportunity in Africa becomes evident. Source: www.engineeringnews.co.za Reliable and cheap energy is possible! The development of micro grids is the ideal solution rather than the expensive diesel generators or other more dangerous means currently being used. The most hazardous of common energy appliances in use in SA is the nonpressure paraffin stove, which is also the main cause of fires and burn injuries. Household air pollution leads to the deaths of 4 million people every year, while burns cause 265 000 deaths, including 100  000 children in Sub-Saharan Africa and Asia. The availibility of PV migro-grids also offers a solution to the biggest challenge in supplying reliable safe electricity. Due to the geography of the countries in Africa, transmitting electricity from a power station to remote areas isn’t just impractical, it’s almost impossible, with long distances to cover and very few customers residing along the lines.

  • Municipalities pushing ahead with plans for more renewable energy
    Local government working hard to meet renewable energy target Loss in annual revenue forcing rethink to approachSome municipalities are pushing ahead with plans for more renewable energy. The City of Cape Town in particular is working hard to meet its target for renewable energy to make up 20% of total energy used in the city by 2020. The city is ramping up various initiatives, including embedded generation, but is hampered by regulatory and policy issues. IPP procurement has been investigated but is currently only allowed by Eskom and requires Ministerial approval. The city says it has lost about 2% in annual revenue in part as a result of the sluggish state of the economy and a migration of electricity consumers to off-grid supply. Because of this, the city has spearheaded a legal challenge to ensure the Constitutional right of the municipality to buy power from independent sources. It is expected that future Eskom tariff increases won’t be as low as right now. With IPPs, municipalities could negotiate tariffs that are less than Eskom’s. Even if Eskom purchases could be offset by 10% to 20%, it would have a knock-on effect that could be passed on to consumers. Some options of growing renewable energy within municipalities include building their own generation capacity by embedding power systems on municipal buildings with or without feeding into the municipal grid. Another option is to build standalone power plants, such as building a solar park on municipal land. There is also potential for procuring electricity from embedded generators or from IPPs. In the City of Cape Town, the uptake for rooftop PV in the Small-Scale Embedded Generation (SSEG) programme has been very positive and is growing at a rate of 6% compounded growth a month, increasing from an installed capacity of 10MW a year ago to 14MW today. 68% of rooftop PV installations have been for domestic installations, although this amounts to only 9.5% in capacity, indicating that the bulk of capacity still lies with commercial installations. The increasing trend for uptake of SSEG is expected to continue because of decreasing solar prices, increasing electricity costs, customers wanting to be environmentally responsible and businesses keen to remain competitive.

  • New Cape Town Solar Regulations
    Grid-tied and Off-Grid systems must be registered Avoid grid disconnection - ensure your customer is registered before February 2019By law, all small-scale embedded generation (SSEG) systems must be authorised by the City of Cape Town. The purpose of registering is: To protect the household from electrical fires and electrical shock To minimise risk to electricity staff working on the grid To maintain power quality and load management Given that there are many systems installed already, the City of Cape Town has allowed a grace period up to 28 February 2019 to register SSEG connections, as home and business owners may not have been aware of the registration prerequisite. The City is actively marketing the requirement. Once home and business owners have registered their system, they have six months in which to prove compliance and receive written authorisation from the City. After the grace period, unauthorised SSEG connections will be disconnected at a fee. Grid supply to the home or business will be disconnected and will only be reconnected once the City is satisfied that the SSEG system is either disconnected, decommissioned or authorised and that the service fee has been paid. Home and business owners that took advantage of the grace period to register the PV Systems will be allowed to continue operating their system. Should a system then be found to be non-compliant during the registration and authorisation process, the system will need to be disconnected until such time as it is compliant and the owner has received written authorisation from the city. Both grid-tied and off-grid systems must be registered. Source: businesstech.co.za How to register a PV system with the City of Cape Town Step 1: Download, complete and submit the Application for the Connection of Small-Scale Embedded Generation (GEN/EMB) form and the Application for a New or Modified Electricity Supply Service form. These forms require technical information which the installer should have handy to assist the home or business owner with. The owner should then email the completed application forms to the listed email addresses only.Step 2: The City will then assess the owner’s registration for authorisation. Step 3: After all relevant information has been provided, the City will issue a “Permission to Install” Letter, allowing the owner to have the proposed system installed. No photovoltaic (PV) generating equipment are allowed to be installed until this letter has been issued.Step 4: After the system has been installed and tested your customer will need to submit the following three documents to the City: SSEG Installation Commissioning Report (found in Appendix 1 of the “Application for the Connection of SSEG form), signed by an Engineering Council of South Africa (ECSA)-registered electrical professional Final copy of the circuit diagram Electrical installation Certificate of Compliance (CoC). Step 5: The City will contact the owner to arrange an appointment to sign the Supplemental Contract for Embedded Generation. A Commissioning Approval Letter will then be issued within ten working days. ...
