RENEWABLE ENERGY and YOUR SYSTEM DESIGN

Bringing light into the dark…

Every solar system should be individually sized. Designing a solar system is a little more complex than just fitting a few panels onto your roof and wiring these up to your DB board via an inverter. Every system is unique and should be custom designed in order to reach its peak performance. Furthermore, local and national regulations must be adhered to

The South African consumer was hit with a 18% electricity tariff increase in 2023. Another 18% is expected for 2024

South Africa has one of the highest Solar irradiation levels (Sun’s Energy) in the world, producing high yields for a well designed Solar system and ensuring a lower cost per kWh generated when compared to Europe. Internationally PV system costs have been decreasing by 8% to 10% a year resulting in PV in South Africa having reached a power production cost of between 74c/kWh and R1.36/kWh, depending on the design and environmental influences of each specific installation.

In order to maximize the return on your capital outlay, a proper system design is essential. You cannot size a system by simply looking at a picture of a DB and roping in the help of Google maps. A site consultation and analysis of your load profile together with the existing infrastructure and general cabling is a must, failing which, someone will get hurt!

In light of the above we offer a free on-site consultation and evaluation. Please feel free to arrange for a meeting. Once all the vital information has been obtained the Design & Engineering of your photovoltaic system will follow. Since Solar PV has a 25 year life expectancy, getting it right in the beginning is key to your enjoyable journey with Solar. We will make it happen.

GoodWe HCA Series AC Wallbox available in 7kW single phase, 11kW 3~phase or 22kW 3~phase.

GoodWe EV Charger has 3 different modes.

1. Fast charge mode

The EV Charger system will charge the electric vehicle at maximum power. if the stoage inverter using self cosummption mode then during the daytime, PV supports the home loads and EV charger at the same time, If PV is insufficient, the battery will discharge to the home loads and EV charger. If battery discharge power is not enough to support the EV and home loads,home system will buy power from grid.

2. PV Priority

The EV charger system will only utilize the remaining PV power to charge the EV. During the daytime, the PV system will prioritize supplying power to the home loads. Any excess power will be used to charge the electric vehicle.

When customer enable Ensure minimum charging power function , when PV surplus is lower 4.14kw(for 3 phase charger) or 1.38kw (for one phase charger), it will continue charging at 4.14 or 1.38kw,EV will get the power from battery or grid. When PV surplus is higher than minimum charging power, it will charge at PV surplus.

3. PV+Battery

The EV charger system will use PV power and battery to charge the electric vehicle. Normally, the EV system do not get the power from grid. But when customer enable Ensure minimum charging power function, when PV surplus is lower 4.14kw(for 3 phase charger) or 1.38kw (for one phase charger), it will continue charging at 4.14 or 1.38kw,EV will get the power from battery or grid

BYD has been making waves in the automotive industry with its high-quality and eco-friendly products that have helped to reduce carbon emissions worldwide, and its latest offering to South Africa is the BYD ATTO3 model. As a C-segment SUV constructed on BYD’s e-Platform 3.0, BYD ATTO 3 exhibits exceptional performance in terms of intelligence, efficiency, safety, and aesthetics. Due to its superior aerodynamic design, it can accelerate from 0 to 100 km/h in just 7.3 seconds and has a drag coefficient as low as 0.29Cd. Additionally, the vehicle can offer users a more convenient and comfortable urban commute thanks to its 420 km pure electric cruising range under WLTP conditions. From family trips to city commutes, BYD ATTO 3 will meet the diversified needs of South African customers in various driving scenarios.

BYD developed a Lithium Iron blade technology which is 100% safe, having passed the dreaded nail penetration test successfully. While undergoing nail penetration tests, the Blade Battery emitted neither smoke nor fire after being penetrated, and its surface temperature only reached 30 to 60°C. Under the same conditions, a ternary lithium battery exceeded 500°C and violently burned, and while a conventional lithium iron phosphate block battery did not openly emit flames or smoke, its surface temperature reached dangerous temperatures of 200 to 400°C.

The Blade Battery also passed other extreme test conditions, such as being crushed, bent, being heated in a furnace to 300°C and overcharged by 260%. None of these resulted in a fire or explosion.

This implies that EVs equipped with the Blade Battery would be far less susceptible to catching fire – even when they are severely damaged.

The e-Platform 3.0 integrates the ultra-safe blade batteries into the car body, increasing the rigidity of the vehicle and lowering the center of gravity. This results in shorter overhangs and a longer wheelbase,significantly expanding the passenger space.

The ATTO has the first electric power-train with motor, charge controller, Battery management, domain controllers and operating System (BYD OS) all in one unit. This facilitates higher levels of intelligent driving and a power consumption per 100km, 10% lower than that of the same class of models.

Did you know: TESLA, Mercedes Benz and Toyota use BYD Blade technology for some of their EV’s!

The ETTO 3 economy relates to a fuel consumption equal to as little as 3.8L/100km. It only takes 33 minutes to charge the battery from 10% to 80%. Even without solar, the cost/km charging the battery from a wall-plug (or faster charging wall-box) is roughly 1/3 of the cost of fossil fuel of an internal combustion motor of the same class.

Registration and maintenance should not be ignored…

Property owners must register their SSEG, it is not the responsibility and duty of the solar installer. Unless clearly outlined in your solar quotation, your electrician/installer is under no obligation to register your system! An electrical COC is not a registration!

Even a simple inverter-battery back-up only system needs to be registered with the Municipality as soon as it is connected to your internal wiring (DB)!

–

Registration:

Local and regional regulations often differ from area to area. All municipalities have their by-laws regarding the connection of solar.

City of Cape Town:

Since 1 October 2023, all new solar PV and/or battery system applications are being treated as grid-tied systems. These include all inverters which are connected to the City’s electricity grid either directly or through your property’s internal wiring, irrespective whether with- or without- solar!

This means that all systems must use City-approved inverter, have professional sign-off and be authorized before switching on. The process can take 3-6 months and involves a time-consuming and frustrating paper trail.

Go-Solar will conclude the registration for all their installations and we also offer to register 3rd party (DIY and other) installations. An admin fee of R7,200.00/installations will apply. This includes:

* Complete the application form/s for your type of installation (grid-tied, grid-tied hybrid, grid-tied battery and solar PV), including required line diagrams

* Obtain written clearance (where necessary) from other City departments;

* Inspect completed installation and conduct required tests. Issue Pr.Eng sign-off documentation.

* Submit the required application form/s and supporting documentation to the Customer Support (CS) office in your area. N.B.: Owner to issue/supply to us the the respective electrical COC, alternatively we will appoint our electrician at an extra cost of R800.00

* Complete the Supplemental Contract with the assistance of Service Connection Planning

* attend to metering changes as applicable (split pre-paid or AMI for feed-in) AMI meters will be quoted for by the city ad are payable to the city by the property-owner.

–

Maintenance:

Just like any motor vehicle, heat-pump, air-conditioning unit or other electrical and/or mechanical equipment, solar needs to be regularly maintained and can command attention from time-to-time.

Unfortunately maintenance is not included in the initial capital investment with any solar system installation and call-out fees will apply for general maintenance.

It is recommended to:

* Check electrical (DB) and solar wiring every 6 months, this would also be in line with your normal electrical maintenance and existing COC. A report outlining the various checks conducted will be submitted on completion, which you in return should forward to your insurance.

* Perform solar panel cleaning between two and four times per year, depending on tilt and orientation (ONLY special solar wash for cleaning and protection should be used). Professionally cleaned panels will increase your solar yield and increase your overall energy cost savings.

* Tighten bolts and screws and inspect your roof in general (as part of panel maintenance) to avoid leaking in case of cracked tiles or damaged waterproofing. Maybe your flashing can do with a coat of waterproofing paint too?

Furthermore there is often a need for a firmware update for your inverter and/or battery management unit and clients often require configurable parameters (depth of discharge, time of charge etc) to be adjusted.

Regulations and requirements (local government and insurance companies) also change and we can ensure that your system remains fully compliant.

With our maintenance plan options Our standard call-out fees are discounted and some may even be waived, depending on customer’s choices and needs. Various plan options are available and can be negotiated accordingly, depending on system size and location.
