Photovoltaic (PV)
Southern Africa has some of the highest levels of direct normal irradiance in the world! This is an ideal environment for solar solution because every Rand spent on solar solution is more productive than in most other parts of the world... by harnessing this radiation ad converting this to electricity - Total energy independence (no more power failures, power surges) is within reach with a Solartech solar system, engineered to meet external power sources such as wind, diesel or even the national grid.
Imagine switching on the lights during a power failure, leaving your neighbours in the dark.
Solartech follows certified energy needs analysis process designed to help match clients power needs to the best suited solar solution. Thereafter, we measure clients energy needs to ensure the correct system size is recommended. Finally, our trained installers ensure a hassle free installation scheduled at a time convenient to the client. Solartech makes use of our sister Solsquare for the procurement and engineering of all our PV systems.
Solartech PV solutions cater to all four need requirements of the market
* Savings
* Power independence
* Lack of power
* Moral obligation

Solar Power
We provide a full range of solar power systems, including solar panels, inverters, charge controllers, solar batteries and top-of-the-range monitoring systems.
Solar Panels
Space, Cost and Efficiency. The right solar panel for the right job!

Inverters
Inverters convert battery direct current (dc) to standard alternating current (ac) or “household” current.
Read more
Charge controllers
Charge controllers are key in ensuring maximum battery life. A battery connected directly to a PV module would overcharge and suffer permanent damage. Thus the need for a charge controller is absolute essential.

Monitoring Systems
Solsquare can enable you to get your system’s information and date anywhere you are and go. The simple and user friendly devices from SMA and Victron, top leading brands in the industry, give the consumer the option to control their solar investment without even being on-site.
Different systems for different solutions
Grid-tie Systems / Off grid system
Island Systems
Multi-Hybrid Systems

Island Power Systems (220Volts/380 Volts)
Energy Generated from the PV modules is used by inverters to produce 220Vac power. Surplus power is stored in the batteries to ensure power availability when usage exceed PV production. Battery storage is sized in order to achieve about 3 days autonomy. As the batteries will be Working on a daily basis, cyclic batteries should ideally be used . The Victron Multi and Quattro island systems are true hybrid inverters. True hybrid inverters have the ability to select how it will interact with grid supply. If grid supply is in the form of national grid, a true hybrid inverter can be programmed to ignore the dedicated supply and only accept due to low battery or load exceeding inverter specification. In the case of generator supply it can manage the generator and can be programmed not to overdraw the generator. True hybrid inverters are expandable in parallel and three phase. Advantages * Grid independence * Expandable into parallel or three phase * Reliable power supply with grid/generator backup Disadvantages * Batteries will be cycling on a daily basis. * Once battery capacity is reached power generated by the PV system is dissipated * Battery capacity needs to ensure autonomy for about 3 days |
Multi Hybrid System
This system consists of 2 alternative energy systems working together. An island system secures backup power to the “essential” appliances. A Grid-connected system feeds power to both the essential and non-essential appliances. The topology of a multi hybrid system allows it to function as a full island system under grid failure, ensuring an unlimited power supply to all the essentials. As the grid-connected PV system is usually sized to serve both the essential and non-essential appliances, it is well oversized in case of grid failure to supply the essential appliances. As the batteries will only cycle in case of grid failure, standby batteries can be used that can achieve similar life to that of cyclic batteries but are far more cost effective. Battery backup is then only sized for essential appliances and therefore significantly less than typical off-grid applications. Advantages * Reliable supply for essential appliances * Batteries will not be cycling if grid power is available * Battery backup is only for essential equipment resulting in a reduced battery bank * Standby batteries in this application can achieve similar life to cyclic batteries in a cyclic application * Expandable in both the island and grid capacities * Surplus power is fed back into the grid and not dissipated as in island systems * Essential appliances can be selected and added Advantages * Only partial grid-independence is achieved |
