Why Solar Now ?

There might be several reasons to consider an investment in solar. Concern for the environment, an effort to reduce carbon fuel usage, avoidance of the frustrations of load shedding or cable theft and non-availability of utility power comes to mind, but ultimately the financial benefit is usually the deciding factor in the justification of an investment in solar.

The financial justifications are different for domestic and commercial installations. One major factor is the tax legislation.

For registered businesses there are two possible TAX benefits.

  • VAT registered businesses, might claim the input VAT. At the current VAT rate of 15%, this is a sizable benefit. 
  • Secondly, under certain conditions the full capital amount of the solar investment might be written off in the first year. With current company tax rate of 28% this is a huge benefit.  
  • If both benefits can be claimed, almost 39% of the total purchase price can be claimed back from the receiver of revenue, leaving only 41% to be justified by cost savings or other benefits like better availability, fewer business interruptions etc.
  • Many businesses operate mostly during daylight hours. For such businesses, a solar system, in grid tie configuration, i,e, without batteries,  could benefit from relatively affordable capital investment and very short payback times.
Section 12B(1) and (2) of the Income Tax Act provides for a 50/30/20 income tax deduction in respect of certain machinery or plant owned by the taxpayer and which was or is brought into use for the first time by that taxpayer, for the purpose of his or her trade to be used by that taxpayer in the generation of electricity from, amongst others, photovoltaic solar energy (both for energy of more than 1 megawatt and energy not exceeding 1 megawatt) or concentrated solar energy. The tax deduction also applies to any improvements to the qualifying plant or machinery which is not repairs.
In cases of plant and machinery used in the generation of electricity from photovoltaic solar energy in respect of energy less than 1 megawatt, the taxpayer may write off 100% of the costs of such plant or machinery in the year brought into use.
Taxpayers installing solar energy systems should therefore carefully consider the tax deductions in terms of section 12B to ensure that all relevant costs are claimed for income tax purposes.

For domestic households no tax advantages are available, but usually the solar systems are much smaller and lower cost than commercial installations. The benefits of load shedding or power interruption immunity as well drastically reduced energy bills are often justification enough to make the solar investment. Since 2007 electricity prices increased more than inflation. The uncertainty regarding future pricing does not help either. Most average households  currently pay approximately R2.30 per kWh and future prices increases are under huge price pressure. Double digit increases are not out of the equation.

Yep...its a lot to take in, But don't stress yourself out because TSA Green does have a couple of Turnkey Solutions that can accommodate everyone who is looking to invest in Renewable, Reliable, Accessible Clean & Green Energy Today.

First of All, What Is Solar Energy & How Does It Work ?

According to Wikipedia, Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies.  Hence, solar power is an alternative, renewable energy source.

How It Works

Solar energy is collected and turned into electricity by photovoltaic solar panels. Any home or business that switches to solar energy will have some sort of solar panels installed on the property. But how, exactly, do these solar panels work and bring electricity to your home?

Solar panels collect energy from the sun and convert it into electricity which is sent to the inverter.  The inverter is one of the most important components of a solar power system and has two very important functions. It takes the electricity from the solar panels and charges the batteries as well as convert the DC from the batteries and solar panels into 230V AC. The AC electricity is then fed into your home to power your lighting and household appliances. There is no need to change any of your lighting or appliances.


Any excess solar power that is not used during the day is used to charge your battery storage system. The battery storage system supplies power to your inverter at night or when there is insufficient solar power available to satisfy your power needs. The system uses an automatic change over switch to ensure you still have power from Eskom on occasion when there is not enough solar and battery power available. This way you are almost certain to have power available at all times, day and night.



A grid-tied solar systems are by far the most common and widely used by homes and businesses. These systems are connected to the public electricity grid and do not require battery storage


Modern hybrid systems combine solar and battery storage in one and are now available in many different forms and configurations. Due to the decreasing cost of battery storage, systems that are already connected to the electricity grid can start taking advantage of battery storage as well.


An off-grid system is not connected to the electricity grid and therefore requires battery storage. An off-grid solar system must be designed appropriately so that it will generate enough power throughout the year and have enough battery capacity to meet the home’s requirements, even in the depths of winter when there is less sunlight.


It really comes down, mostly to what your energy needs are and your budget. Many homeowners are installing solar power systems to reduce their reliance on Eskom, lower their electricity bills, and make their homes more environmentally friendly. Most electricity in a home is used in the early mornings and evenings and not during the day when solar power production is at it’s maximum.  For this reason we recommend using an off grid or hybrid system with lithium battery storage to store solar power generated during the day and make use of all this stored energy to power your household lighting and appliances at night.


TSA GREEN provides residential solar systems from a wide range of starter systems that just run the basics to full off-grid systems that can run a whole house independently and are designed to save you money and protect you against power outages and load shedding.


When it comes to running a business, the goal is to maximize profits by saving on expenses. When you switch to solar, you're one step forward in that direction and TSA GREEN has a variety of solutions to meet up with your needs when it comes to your Business which will save you on your bills and can enjoy: *Increased profit margins *Lower operating expenses *Substantial tax and depreciation benefits

                                                               Our Process

                                               In order to design and install a suitable solar system the following steps are followed:

Step 1: Initial Discussion

An initial discussion is conducted to understand the strategic goals for the installation. Is the aim to save electricity costs, to protect against load shedding and power interruptions, to reduce the carbon footprint etc.

Step 2: Usage Evaluation

An energy logger is installed to measure and log the actual electricity usage, over a period of time. Electricity bills do not provide enough detail do proper designs. Firstly, electricity bills are often estimated and not actually measured. Secondly an electricity bill provides no detail of usage patterns like maximum demand, or usage per day and night.  Important data that are recorded on the logger and used in the design of a suitable system are:

  1. The maximum power used at any point in time.  This will influence the inverter choice in terms with maximum power that the unit must be capable of delivering.
  2. The average electricity usage per day and by extension per month. This will influence the size and number of solar panels needed to cater for the electricity usage.
  3. The usage pattern in terms of the spit between usage during daylight hours and non daylight ours will influence the battery bank design and capacity.
  4. Experience showed that in 3 phase systems, loads are more often than not unbalanced. Proposal can be made to balance the loads better. This can ultimately save costs by not designing unnecessary large systems.

Step 3: System Design

Once the logged data is available a system can be designed to meet the strategic goals and load requirement exactly. Measurements are also made after installation to confirm that the aims of the design are met.

Step 4: Installation

Once designed, the final step is to install your system so you can enjoy clean and green energy.
