Civil Construction

Civil Construction is the creation of infrastructure involving anything to do with water, earth or transport.

It is a branch of Civil Engineering involved with the maintenance, design and construction of both natural and physically built environments such as roads, railways, buildings, water reservoirs, subdivisions, airports, bridges, sewer systems, tunnels and dams.

GS - A3 Solar Power Package

This NO FUSS Entry Level Solar Power package holds enough electricity for 6 hours.

The GS-A3 systems INTELLIGENT INVERTER will first utilise Eskom power, then battery power, and the photovoltaic panels will charge the batteries during the day. The inverter can also charge the batteries at night from the grid if the grid is switched on.

The system will firstly use solar power to charge the batteries. When the sun is not shining it will use a trickle charge from the grid to keep the batteries at optimum level.

In the case of power failure or load shedding the GS-A3 system switches over automatically via extra fast transfer switch to the batteries, within 15 milliseconds. The homes lights will be kept on without disruption. The transition will be seamless.

The GS-A3 system allows for one plug to be used for low wattage appliances

This system is intended for TV’s, decoders, computers, cell phone chargers, lights and similar appliances.

N.B. NOT intended for large electric appliances

Solar FAQ's

Please Note: The section below is only a guideline and very opinionated. “Horses for courses”. You would not use a racehorse for show jumping and vice versa. Hope this helps you to find the right horse for the right course.

  1. How does Solar Power system work?

Solar panels convert sunshine into electricity. These solar panels are made up of photovoltaic cells. When the sun shines on these cells during the day, it gets the electrons on the move. This friction is then converted into Direct Current (DC).

However, Direct Current (DC) cannot be used in home appliances, so it needs to be converted into Alternating Current (AC). Therefore, the inverter is an especially important component of this process. It converts DC (12V, 24V, 48V) to AC (220V).

  1. What does a Solar Power system consist of?

The three main components are Solar panels, an inverter, and batteries. We will start with these three components, but there is much more that we will deal with later.

  1. What is the difference between the various types of solar panels?

Currently there are three types of solar panels. The main difference between them is the type of silicon and how the silicon is used. The power output and warranties is pretty much the same on Mono and Poly. Mono costs a little more.

Solar panel types

  1. Do solar panels need cleaning?

Yes. For maximum output from solar panels, they need to be kept clean of bird poop, dirt and dust. Dirty panels can be up to 25% less efficient.

  1. What type of inverter do I need?

The inverter is the brains of the operation, so depending on your requirements and application, there are three types:

  • Off grid (No backup from Eskom, totally off the grid)
  • Hybrid (Eskom and solar power combined)
  • Grid tied (Connected to Eskom, when Eskom is off, you are off)
  1. What is the best recommended inverter?

Depending on your requirements and application, there are three types.

1   Off grid

Victron

2   Hybrid

Victron year

3   Grid tied

SMA / Fronius

  1. What type of batteries are available?

Depending on what you are willing to spend and how long you want them to last, there are three types. P.S. Yes there are gel batteries also, but not worth mentioning here unless you live on a boat.☺

Lead acid

Most affordable, takes long to charge and usually last 3 to 5 years

Lead carbon

Little pricier, also takes long to charge and usually last 5 to 7 year

Lithium

Most expensive, charge very quickly and usually last you 10 to 15 years

  1. Will solar power save me money?

The short answer is YES. It will cost a lot of money now, but at some stage you will break even and after that you will start saving money.

For example: Assuming your current electricity cost is R2,000.00 per month, over 10 years you will pay R240,000.00 (no escalation on tariffs included). If you spend that amount now upfront you could have free electricity after year ten.

The added benefit for South Africans is that you will have electricity power when there is load shedding, cable theft, transformer blow out, etc.

  1. Does it improve the value of my house?

It most certainly does. We do advertise solar power with the house extras, and potential home-buyers are requesting it more and more. If solar power is already in place and it eliminates the hassle of a home-buyer having to worry about installing one themselves, they will be more inclined to seriously consider purchasing your home over another.

    10. If solar power is so great, why don’t more people use it?

My favourite question! It is probably one of the fastest growing industries in South Africa now. The primary factor is cost (I will deal with cost in the next question). The second factor is the unknown. People know Eskom, and know what they can expect. With solar there is a big unknown. 30 Years ago, Toyota was often referred to as Jap scrap, today it is one of the best vehicles around. People also do not know that Solar systems can also be modular, every two or three months you can buy and add to your system (just like Lego). When you buy a solar system, you are purchasing your very own little power plant.

    11. Will solar power get cheaper?

Over the last 10 years solar power prices have been steadily declining. I paid three times the price five years ago, for what I would pay now. Over the past year prices have remained steady, but are likely to start increasing again, depending on the demand. The best time to buy is now!

    12. Do I need a certified electrician to sign off?

No, but it will soon become law. If you want to sleep at night and not wonder if your house is going to burn down, I recommend you get an electrician to do the job. Plus, insurance companies will not pay out if a CoC (certificate of compliance) for the solar system was not issued.

    13. What else do I need? (the important stuff).

  • DC fuses.
  • Surge arrestors.
  • Battery fuses.
  • Proper earthing.

    14. Can solar panels be installed on my roof?

Yes, we can install solar panels on any type of roof. Flat, corrugated, IBR, clip-lock, tile, etc.
