At Sonop Solar we expertly install solar systems in the Western and some Northern Cape region of South Africa. Our efficient Solar installations teams are all PV Green Card accredited with years of electrical and solar experience.

Technical personal will be in charge of pre-site monitoring, designing and programming the correct systems and solar products to your needs. Qualified engineers ensures that everything structure wise is to standard, while electricians will ensure that the AC part of the installation is in good order.

We supply our installations clients with a certificate of compliance along with a project report that includes, serial numbers, maintenance suggestions and the Installation summary.

Stand Alone System / Off-Grid System

If you are living in a remote area where you are not connected to the main electricity grid or want to be 100% independent in your power use, installing an off-grid solar power system for your electricity needs could be the best solution.

If you decide to go off grid, you will need solar panels, a charge controller, an inverter and batteries where you can store excess solar electricity. These batteries will supply you with energy even when there is no sunshine.

The sun generates DC power which is then fed into a regulator/charge controller to charge the batteries. The inverter the converts the DC power from the batteries to AC power which will supply your loads.

The sun shining onto your solar panels will generate DC (direct current) electricity, which is fed into a regulator . Once your batteries are charged, you can run your electrical appliances directly off the batteries or route the direct current through an inverter which converts the electricity and will let you run all your standard household appliances.

Example: 5 kVA Stand-alone system

5 kVA inverter/charger

100 Amp charge controller

12 x 400 PV Modules

5 x 2.4kwh Lithium batteries (12kwh) rated to discharge to 80% = 9.6kwh

Combiner box, fuses, breakers, cable, railings, connectors.

Backup power :  9.6kwh discharging @ 500wh = 19 hours more or less

Grid-Tie Systems (1.5 kW – 1 MW)

This is a system where you are connected to the grid. DC power from the PV modules is converted by the grid-tied inverter to AC power to feed your consumption during the day and feed excess power back into the grid.

This is dependent on your municipality regulations.  If the regulations does not permit it an external meter to limit excess power being fed back into the grid will be installed.

There are no batteries involved – the utility is the battery. So when the utility is off, your system is also off. This system offers massive savings on your electricity bill. Batteries can be connected at a later stage with an additional inverter, this is only possible with selected brands.

Example: Average house uses 1000 units per month

1000 units ÷ 30 days ÷ 5.5 sun hours = 6.06 kW/h

6 kW grid-tie inverters

16 x 400 W PV Modules (6.4kw PV)

Railings, cable, connectors, breakers, fuses, etc.

Hybrid System

Hybrid Solar Systems runs on solar power or mains power or both, with battery backup for power outages or period of no sun. All excess power generated by the solar panels is able to be returned to the grid.

Hybrid solar systems combine the best from grid-tied and off-grid solar systems. These systems can either be described as off-grid solar with utility backup power, or grid-tied solar with extra battery storage.

Hybrid non-grid feed in, which is for backup and self-consumption, are connected to the PV modules, utility or generator, batteries and to the load. There is no need for a charge controller/regulator.

Example: 5 kVA

5 kVA hybrid inverter

12 x 400 W PV Modules

5 x 2.4kwh Lithium batteries (12kwh) rated to discharge to 80% = 9.6kwh

Combiner box, fuses, breakers, cable, railings, connectors.

Backup power :  9.6kwh discharging @ 500wh = 19 hours more or less

Battery Backup/UPS

We have UPS or backup solutions for when the utility fails. When the utility fails the UPS changes over automatic within milliseconds. The inverter is sized by your load you want to use and the batteries are sized to the backup time you want when the utility fails.

Example: 5 kVA (4000 W) load for 3 hours backup

Inverter/charger 5 kVA

5 x 2.4kwh Lithium batteries (12kwh) rated to discharge to 80% = 9.6kwh

Cable, breakers, etc.

Backup power :  9.6kwh discharging @ 500wh = 19 hours more or less

Solar Pump System

This pumping solution is used where there is no utility and is too expensive to get the utility on the site. A normal existing 230 V or 380 V pump can be used for pumping. A solar pump controller is used to convert the DC, of the solar panels, to 230 V or 380 V AC.

The system runs only during normal sun hours. Applications from 0.75 kW – 37 kW can be used. The PV modules for this system is sized 1.8 – 2 times the size of the motor. This all depends on how string would work out, sometimes it will be up to 2.3 times oversized. Your pumping cost will be zero for 25 years.

Example: 11 kW pump + motor

11 kW solar pump controller (solar VSD)

64 x 400 W PV Modules = 25.6kw

Railings, cable, connectors, etc.

And your pump is running for FREE!

Upgrade, Repairs and Maintenance

Do you need to upgrade for your solar system or is it in need of a repair or maintenance?

Solar system are prone to give some sort of problem if not maintained, Sonop Solar provides a check list for maintenance as well as suggestions with every installation. If these are followed only a regular yearly maintenance check would be required to ensure that the system is working at optimal.

Technical Assistance and system setup

Sonop Solar offers technical assistance on grid tied systems, off grid systems, hybrid systems and solar pumping systems in and around South Africa.

We at Sonop Solar have a lot of technical expertise which could be beneficial to anyone trying to put a system together but don’t know how the components work or are put together to communicate properly with each other.

Some people has the practical and technical abilities but does not know how the certain products are connected to each other.

That is where we come in to try and help you to technical assist you the best possible way we can.

Therefore we ask a separate fee depending on system.

We can also pre build and pre wire a back plate for you for easy installation to basically just plug and play your system.

We advise that the system is at all times installed by a professional who can supply a valid Certificate of Compliance otherwise all products warranty will be void.

System Design

Sonop Solar offers System designing which can be beneficial to someone that has no expertise with PV Systems, for Sonop Solar to design a system we need to determine what your consumption is during daytime and night time, what time of the day you peak power usage is and what your average load and usage are.

For Sonop Solar to do this we need to install an energy logger for 7 – 10 days.

System Monitoring

We recommend all systems to be installed with a monitoring device. This will enable you to track your PV Systems performance. It provides information about energy production, consumption, optimization of energy being used and detect errors if any.

Sonop solar does energy logging in the Western Cape, for us to do a proper system design we need to install an energy logger. We ask a fee depending on area to install an energy logger for 7 – 10 days.

What system monitoring include:

Sonop Solar takes responsibility to check the systems for performance and errors if any if client takes responsibility, client will have to inform Sonop Solar if support is needed to help take a look at the system which will be at an additional fee.

What energy logging include:

  • Install logger for 7 – 10 days
  • Determine what your average and peak load is
  • Determine what your daytime and night time loads are
  • Determine what your total consumption is in 24 hour period is

Financing Options

Sonop Solar does not supply any financing solutions but can put you in contact with the relevant institutions to help you through the process.

There are a couple of options that could be looked at when financing a system.

For individuals and sole proprietors there is Green fin and your own bank. We have found that the best is to use a bond on your property where the system should be installed.

For companies there is financing through your bank and rental agreement.

All the products that we use are bankable products.

The banks are constantly developing new products for the Renewable market, so please get in contact with us for any new developments.
