COMPANY PROFILE

We are a dynamic team with a focus on energy problems in South Africa. We are committed to

supplying the best services and quality to our clients. We have been in Business for 12 years

with 8 technical branches in South Africa and Namibia. Our head office is situated within

Pretoria and our engineering department in Cape Town as well as Johannesburg. Our main

focus is within the residential, agricultural and industrial industries. We have a solution for any

application from power factor correction to solar applications as well as home automation

systems.

We offer a wide range of services from products to installations and maintenance. We have

different solar packages available for residential, office, malls, factories, industrial sites, farms

and remote locations. Our solar products will help you save on your electricity bill, generate your

own energy for your home and make your life simpler as well as helping our environment with

eco-friendly solutions.

We offer a wide range of packages including but not limited to grid tie systems, off grid systems,

micro inverter packages and our power engineer system which includes home automation and

power factor correction. All of our packages can be upgraded when your power needs

increases. All of our inverters, batteries and power banks are state of the art products and are

continuously being improved. We offer installation included in all of our packages which are

done with certified electricians.

SOLAR ENERGY SOLUTION

SYSTEM SPECIFICATION

The 10KVA off grid system comprises of the following:

● 2x 5KVA Off-grid inverter

● 12x 320 Watt Solar Panels

● 2x 9,8 KW/h Battery bank

● Management software

The system will supply you with an approximate total of 39.8 kwh per day at peak performance.

During the day time the system will generate power through both sun and UV rays thus

powering your home through means of solar energy generated by the solar panels. At night time

your home will run on the Battery bank ,consisting of two 9,8 Kilowatt per hour battery banks,

this will give you an estimated usage period of 10 to 12 hours dependant on your usage. In

cloudy weather the system will still generate up to 85% of the energy that is seen in normal

conditions. In rainy weather the system will produce between an estimated 10 - 60% of the

energy that is seen in normal conditions, in this situation the inverter will automatically supply

the additional power from your municipal grid. If however you do not have a grid connection the

system still allows for the integration of a generator to supply power when necessary.

Please note electrical elements such as Stove tops, ovens, geyser elements, underfloor heating

and electric water heating solutions would not be run on this system due to the amount of

electrical kilowatt consumption that these elements use. However smaller or short time period

elements can be run such as a kettle.

However we do offer gas solution to replace these elements and allow you to use them freely at

any given time.

FINANCIAL ANALYSIS

Taking in consideration that the system will produce 39.8kwh per day at peak performance thus

amounting to an approximate monthly saving of R3000,00.

Based on historical data of increases within electrical energy the following chart displays the

approximate amount of savings that would be achieved within a 10 year period if a annual

electrical increase of 20% is taken into consideration


5

Taking into consideration the replacement of batteries after a 8 year period, an 8 year period is

used as a baseline or “worst case scenario”, and the cost of the replacement of the batteries

and the inflation within the 8 year period based on 7%. The estimated cost of the replacement

batteries would be R60000,00.

Thus your approximate total savings within the 10 year period, including the deduction of the

replacement of the batteries, amount to R874510,00.

INSTALLATION

The installation of the solar energy proposal is done by our own qualified electricians. If there

are no complications regarding the installation the installation can be completed in

approximately a single working day.

Please note that our installation does not include the installation of any gas related products.

Should the client require an installer for gas related products Evest can provide the client with

an accredited installers details.
