Solar Energy FAQ

General

What is a grid-connected solar panel system?

With a grid-connected solar panel system, panels are wired to an inverter or inverters that convert the DC power generated by the panels to 230V AC household power, where it is then used to run any electrical appliance.

Is it worth exporting power back to the grid?

To maximize your saving and increase your return on investment you want to be using as much of the power to generate as possible. Exported electricity pays only a low fee and in most cases not worth exporting.

How long does installation take?

Installation will depend on the size of the solar power system being installed but typically takes 1 day to complete installation.

Does solar system work in winter?

Solar Photovoltaic Systems are not reliant on heat, simply sunlight and ultra-violet rays. Cooler sunny days actually provide higher production from the system however we must remember the sunlight hours are less during the winter. When designing a PV system, we take into consideration the change in seasons when estimating the annual energy production.

Do you do off-grid systems?

Yes we can design & install off grid systems, give us a call to discuss in more detail.

Do you do commercial or industrial systems?

Yes we have a project team to manage all commercial projects, give us a call to discuss in more detail.

PV Panel

How much roof-space is required?

The amount of roof-space required will vary depending on the size of the system you require. As a rough guide a 1.5kW system will require about 10m2 of unshaded roof space. The system is modular, which means the panels can be arranged in the best way for the roof.

My roof does not face north, does this matter?

A mounting system can be installed to angle the panels so they collect the maximum amount of energy from the sun’s rays, we assess each house to ensure we get maximum energy generation

Can I add Pannels in the Future?

Increasing the size of your solar PV system depends on two factors: available space on your roof and additional capacity in your inverter. If there is sufficient space free for both, then you can increase the size of your system. If the capacity of your inverter has been reached, you could consider adding a second system to your roof.

What are Optomisers?

Optomiser is a device that get installed on a PV panel or panels that are affected by shade, and maximizes the panels efficiency of that panle so that the shade does not affect the rest of the panels efficiency in that string

What is the warranty on panel?

We only use Tier 1 Manufature, our Trina PV Panels are industry leading for quality and reliability and come with a 25 Year Warranty.

My PV system is not generating the power is is supposed to, what is wrong?

There could be a number of things that could cause this issue, most of the time it’s a faulty panel or string. Give us a call to assist.

Inverter

Do I Need an inverter?

The inverter is the Core of your solar system and converts the solar energy into power that is usable in your home.

What is a Hybrid Inverter?

A Hybrid inverter are used when you have a battery or would like to add a battery in the future. What this video to see the benefits of our X-hybrid inverters Watch Video Here

Where is the inverter installed?

All our inverters are IP rated meaning they can be installed inside or outside mounted on wall.

Do inverters make noise?

Yes it does, Inverters have a slite humming sound depending on the amount of strain the inverter is under. That is why we recommend the inverter to be installed in the garage or simmilar position.

Does the inverter need ventelation?

Yes , we recommend the invereter is installed in a well vented area with free flowing air. Alternatively ventilation needs to be added to the room

Battery

How does a battery work?

Generated power from solar panels during the day will supply background load first and when satisfied, your hybrid inverter will charge your batteries with free, clean solar energy. When the sun has gone down you batteries will discharge your stored energy.

Can I add a battery to my existing system?

Yes is the short answer, although we will need to assess your existing system and allow for extra components depending on your inverter

How long do batteries last for?

Depending on the type of battery solution you sellect the moder day lithium-iron batteries run 6000 cycles estamated to last 15-20 years

Can I power by whole house from Battery in a power cut?

No , a hybrid inverter has a backup load that is prioretised in the event of a power cut. This will only be the essential loads that are agreed apon before hand based on the invertes raiting.

What is the warranty on Battery?

Triple power have battery come with a 10- year warranty

Where is the Battery installed?

The Triple Power battery is IP55 Rated meaning that it can be installed inside or outside and can be wall or ground mounted. But e recoment it to be installed as close to the inverter as possible.

EV Charging FAQ

EV Range

How far can an Electric Vehicle go?

Depending on the battery capacity of your electric vehicle (EV), you can go between 200 to 490 kilometers with one charge.

EV Range Example

The average person drives about 60 km each day and with one full charge you can go for example 240 km with a Renault ZOE or 490 km with a Tesla Model S.

Charging

How long does it take to charge and Electric Vehicle?

The battery capacity of your electric vehicle (EV) will determine how much energy can be stored and, therefore, how long it will take to charge. The battery capacity differs for each car. The Nissan LEAF, for example, has a battery capacity of 30 kW, while the Tesla Model S has a capacity of 100 kW. To figure out how long it takes to charge your battery, divide the battery capacity by the charging power. Fomula use to determin charinging time (Battery capacity / charging power = charging time)

Charging from the grid

There's a maximum deliverable power in all electrical installations. It's the power that your facility can deliver to all electrical devices connected to it. For example, if you have 4.4 kW maximum deliverable power at your house, all devices that are connected to that network can never consume more than 4.4 kW combined.

Charging Time Example

(Battery capacity / charging power = charging time) Battery Capacity of your EV is 30kW, charging power is set at 4.4KW charging time would therefore equal 7 Hours

What is the Power output of EV Chargers?

Every charger has a maximum of power that can be transferred from the installation to the vehicle. All our chargers can charge between 7.4 kW and 22 kW. A direct current (DC) charger can charge up to 350 kW.

Why do I need an EV Charger?

Charging your EV with a charger is safer, faster and cheaper. Safer, because the charger is smart and will control the flow of energy through the cable. Fast, because charging with a charger is about eight times faster than with just a cable. And last but not least affordable, because you can charge your car at off-peak times.

How much does it cost to charge and Electric Vehicle?

The cost of charging your EV depends on the electricity rates from your power retailer, some retailers also offer a low rate to charnge your EV over night when demand is low. As a rough guide EV Charging is equivalent to paying 30c per litre of pertrol

Whats the difference between AC & DC

The difference between AC charging and DC charging is the location where the AC power gets converted; inside or outside the car. Unlike AC chargers, a DC charger has the converter inside the charger itself. That means it can feed power directly to the car's battery and doesn't need the onboard charger to convert it. DC chargers are bigger, faster, and an exciting breakthrough when it comes to EVs.

Smart Charging

What is Smart Charging?

Smart charging means you can intelligently manage how your electric vehicle charges by connecting it to the grid to manage their charging points remotely and, through this, to optimize energy consumption and costs. For instance, setting your charging to start at night when rates are lower.

What is Power Sharing?

Power Sharing, also sometimes referred to as load balancing or levelling, allows network operators or businesses with multiple chargers onsite to distribute the available energy capacity proportionally across all active EV charging stations. Watch this video to learn more Watch Video Here

What is Bidirectional Charging?

Bidirectional charging, on the other hand, is where energy can flow both into an EV and out of it via a special bidirectional charger, often referred to as V2G (vehicle to grid). This means that the EV battery can both take energy from the grid and give energy back to it. You can check the video below to see how this works in practice. Watch Video Here

Whats the difference between Smart Charging and Fast Charging?

Fast charging simply involves putting more electricity into an EVs battery at a faster rate - in other words, charging up an EV’s battery quicker. Smart charging, as we saw above, allows vehicle owners, businesses and network operators to control how much energy EVs are taking from the grid and when to use provide charging.

Charging Types

What do I need to know?

There are 4 types of plugs exist, two for alternating current (AC) which allow charging up to 43 kW and two for direct current (DC) which allow fast charging up to 350 kW.

What is a "Type 1" AC Plug?

Type 1 is a single-phase plug and is standard for EVs from America and Asia. It allows you to charge your car at a speed of up to 7.4 kW, depending on the charging power of your car and grid capability

What is a "Type 2" AC Plug?

Type 2 plugs are three-phase plugs because they have three additional wires to let current run through. So naturally, they can charge your car faster. At home, the highest charging power rate is 22 kW, while public charging stations can have a charging power up to 43 kW, again depending on the charging power of your car and grid capability.

What is "CHAdeMO" DC Plug?

This quick charging system allows for very high charging capacities as well as bidirectional charging. Currently, Asian car manufacturers are leading the way in offering electric cars that are compatible with a CHAdeMO plug. It allows charging up to 100 kW.

What is "CCS" DC Plug?

The CCS plug is an enhanced version of the type 2 plug, with two additional power contacts for the purposes of quick charging. It supports AC and DC charging. It allows charging at a speed of up to 350 kW.

Ventilation FAQ

General

What the difference between a Positive and Balance pressure system?

Positive Pressure Systems; draws air from the roof cavity. The air is then passed through a filter and introduced into your home to positively pressurize with fresh, clean air and force out moist, stale air. Postive pressure system are particularly well suited to older homes where timber joinery and older aluminium joinery allow air to be forced out more easily and create better air circulation. Balance Pressure Systems; are heat recovery ventilation system that simultaneously supplies fresh air from outside while extracting the moist, stale air from inside. Balance pressure system are particularly suited to modern homes that are better insulated with modern joinery which results in homes being more airtight.

Where should outlets go?

We recommend that you place an outlet in your living areas and bedrooms. With regard to placement within each room, the outlets should be located centrally within each room. Away from any windows and doors so the air has time to circulate within the room prior to escaping out any windows or doors. Outlets should be installed at least 1m away from security sensors, smoke alarms, and wall

What do the outlets look like?

They are circular vents, for installation in the ceiling. We also have options for wall grilles, please contact the Future Team for more information Contact Us Here

Are Smartvent system expensive to run?

SmartVent systems cost from as little as 35 cents per day to operate. *Based on the fan(s) power consumption on maximum speed, running 24 hours per day, over a 30-day period, at $0.26/kWh

Where can I buy my filters?

We offer filter replacements, contact us to confrim price and time to come out and replace, Contact Us Here

Does Smart vent control humidity?

Our SmartVent evolve monitors temperature and humidity levels to give you the driest possible air possible from the roof cavity and/or outside (optional). The air is then passed through a filter and introduced into your home to positively pressurize with fresh, clean air and force out moist, stale air and is controlled via a Wi-Fi-enabled device.

What is Heat recovery system?
