Solar Systems

Solar PV Systems are available in several different design options.

The basic components of a Solar system are:

Solar PV Modules (Panels)

Inverter

Battery

Solar PV Modules converts sunlight into electricity. These are available in different sizes, efficiency and power ratings.

We only supply panels from the Top Tier manufacturers – these are the largest global manufacturers, AND have the best quality rating as per independent survey by Bloomberg.

Inverters receives electricity from Solar PV modules and converts that electricity from DC to AC.

Inverters differ based on function and output (size). There are 4 basic types of inverters (and this determines the type of system)

Hybrid

Grid Tied

Bi-Directional

Off Grid

Batteries stores electricity for use at a later stage, either during power outage, or when Solar Power is not sufficient.

Batteries are available in many different options based on capacity, lifespan, efficiency, durability & cost.

Typical batteries used in Solar Deepcycle applications are:

Lithium Ion

AGM Gel

Lead Acid

We will assist in advising the best battery solution for you based on your individual requirements

Below is typical example of power consumption and Solar Power generation Typical power usage peaks in the morning & evening. Solar generation peaks in the middle of the day. This could result in a mismatch between Solar Power generation and power usage. If the Solar generation is less than the consumption, all the Solar Power will be used instantaneously. If the power generation from the solar is more than usage, batteries are used to store solar power during the day and use that stored power during the night. Depending on the size of the solar system vs consumption, Selecting the right system or you: Do you want Solar with battery back-up: Hybrid Do you want Solar Power during day and night: Hybrid Can you feed power into the Grid (use the grid as battery): Grid Tied Do you only want Solar Power during the day: small Grid Tied Is the majority of your consumption during the day: small Grid Tied OR Hybrid

Off Grid systems means you’re not connected to the SpecEnergy grid.

This solution is ideal for the following scenarios:

• You’re building on a new property and the cost of bringing in an SpecEnergy service is too high
• You wish to be completely independent of SpecEnergy
• The monthly fixed connection cost from SpecEnergy is exuberant relative to the consumption cost

Off Grid systems consists of the following components:

Solar modules that collect sunlight and convert it into DC power

• Inverter (with built-in charge controller and regulator) which:
• receives DC current from Solar modules
• charges batteries with DC current
• discharges batteries and converts it into AC power for supply to the building



Deep cycle batteries which are managed by the inverter to be correctly charged by Solar & discharged to supply power to the building

Off Grid systems are typically over designed to include more Solar modules and more battery capacity in order to cater for days of poor weather conditions.
During poor weather, i.e. rain, there is little or no Solar power generation. The battery capacity needs to allow for this in order to ensure a continuous supply of electricity.



Likewise the Solar generation capacity is oversized so that it can accommodate recharging the extended battery capacity and simultaneously supply power to the building.

Due to the overdesign of Off Grid systems, these have typically a longer Return on Investment.

Off Grid systems can be designed to run in conjunction with generators, and even to use generators to recharge batteries. This can result in smaller battery capacity and thus reduction in initial capital cost.

Grid Tied Solar systems are the most popular and economical system and a good step to going green.

Grid Tied systems are ideal for saving electricity costs and reducing monthly expenses, and offers the best Return on Investment

A Grid Tied system is very simple in design and consists of the following components:

Solar modules that collect sunlight and convert it into DC electricity

Inverter which receives the DC current and converts it into AC grid power

The solar generated power is connected through the inverter to the building’s grid at the main distribution board.

The inverter facilitates a seamless, dynamic interface between Grid Power and Solar Power, ensuring that there is always power supply going to the building and prioritizing the Solar Power supply so that the solar power is used first. For example, if the power consumption is 100kW and solar is generating 95kW, then:

95kW will be supplied from Solar with the inverter ensuring that the 95kW from Solar is used first

Grid power will supply the balance of 5kW

If power consumption is less than Solar Power supply, then no power will be drawn from the Grid.

There is no switching between Solar Power & Grid Power, but rather a continuous supply of both Solar Power & Grid Power with Solar Power supply being the first priority. Subsequently there is no dip in power supply to the building, and therefore the Grid Tie solution is safe to use with any and all sensitive equipment, including PC’s.

Grid Tie systems are fully expandable so that more Solar PV Panels can be added to the system to generate more Solar power. Battery Systems can at later stage be incorporated with Grid Tied systems.

Grid Tie systems can be added to existing warehouses, packaging plants and manufacturing plants or can be incorporated into the design and building of new premises. Grid Tied systems are available in Single Phase and Three Phase. There is no limit to the power supply potential of Grid Tied systems and can be implemented for small buildings with low power usage or big manufacturing plants with high power consumption.

Our Grid Tied system are compatible with Generators and UPS’s and are capable of Grid Feed-In

Grid Tied System are suitable for medium to large domestic, and all commercial and industrial applications.
