Skylights

Copy of Skylight

A lot of houses have a place that is dull and dreary, with little or no sun getting in. We can
bring light to these places with our range of Suntrenz sky lighting systems.

Our Skylight systems have been made with the New Zealand customer in mind. Made in New Zealand, for New Zealand; we are equipped to understand the unique environment of our country. The harsh environment requires a well built, durable product that can withstand sun, wind, rain, hail and snow.

The Suntrenz range has only one roof component ­ which matches your existing roof profile and is least likely to leak. They are made to fit most concrete tile, steel decorative or corrugated roofs.

Advantages over more traditional skylights

How does my skylight work?

skylight after 1 (1)

Skylights work to capture and transfer light from the roof to the room. Our New Zealand made skylights have been manufactured to maximise available light. It’s simple design is able to capture light and transfer it from morning till dusk ­ as long as there is light in the sky.

The captured light is reflected down the super tube light shaft and into the room. The highly reflective super tube light shaft intensifies the sunlight and provides maximum light availability. The light from the shaft enters the room through the diffuser.

It’s design spreads the light over a wider area than the spot light effect seen in some more traditional models. Tubular skylights consist of a transparent dome on the roof, a light shaft and a diffuser in the ceiling.

Two types of Skylight Tubes

Rigid Tube
The rigid tube is our most efficient option for transferring light. It’s smooth sides maximise light transfer.

Concertina Tube
The light transferred is considerably reduced, but is a cost effective option.

Underfloor Heating

Underfloor Heating

underandradiator

Underfloor heating is the most comfortable form of heat.

  • No drafts
  • Only a small amount of moving parts ­ therefore extremely durable
  • At a similar price to other forms of whole house heating
  • It is the only form of heating that heats from the ground up rather than from the roof down meaning warm feet and cool head rather than the other way around

With over 20 years experience in heating homes in both the UK and New Zealand ­ we have brought together a unique package which provides a quality, cost effective system to heat your home.

Rehau underfloor heating: Rehau pipe is made in Germany, it has all the certifications for large commercial to small domestic uses. It has an oxygen barrier in the pipe to ensure that pipe does not breakdown over the years through oxygen bubbles eroding pipe bends.

OJ Electronic controls provide the latest in temperature control. With PID control, the
thermostats predict the temperature rise in a home and shut off the heat early to stop over heat issues. We can use floor probes to give best response to changes in the environment for example solar gain. We also as standard use individual room and zone thermostats ­meaning the heat goes to where it is needed rather than send heat to the whole house all at once. All together this system supplies the greatest comfort at the lowest running cost of all
underfloor heating systems on the market. OJ electronics also offer a WiFi package so you can heat your house from your PC or smart phone.

We also provide Purmo radiators, Myson Fan Convectors and a full range of heating controls, both hard wired and wireless.

Design & Build

Design

design_and_installation1

Sunshine Solar can design and size a system to suit your requirements. Sunshine Solar can help you identify what alternative energy sources are available for heating water and spaces, alleviating the amount of power needed from your solar power system.

A battery bank will typically need replacing in 5-15 years, depending on quality, sizing and how often you use them. There are issues that arise if your battery bank is too small or too large. Too small and it may be discharged at a low level too often – shortening its life. If it is too large, it will cost you more and it may not fully charge regularly – shortening its life. Sunshine Solar will help you choose the right sized battery bank for your needs. We also provide a maintenance programme to help you keep your batteries in good working condition for longer.

You will need an inverter which converts electricity from direct current (DC) electricity to alternating current (AC). Sunshine Solar recommends using advanced inverters specifically for stand-alone power systems that control your generation units and how much electricity your house is using at any time. We can help you choose the right size and type that is compatible with your appliances.

Sunshine Solar has extensive experience in designing and installing stand-alone solar power systems that meet the requirements of local and regional councils. We project manage your installation and will assist you in gaining the necessary building and/or resource consents. We remove the stress of liasising with the planning and/or building consent officer at your local council on your behalf. This ensures that you have peace of mind and know that the right processes are being adhered to.

Saving Cash – Saving Power

The biggest advantage when it comes to solar energy is that solar energy systems are powered by the sun, and sunlight is free. Your house does not have to be in direct sunlight all day in order to benefit from solar, and solar energy systems ‘store’ power during the day, so don’t think all your appliances will be useless once the sun goes down. Solar energy systems still draw power from the sun even on cloudy days.

 

It is possible to install enough solar panels on your roof so your home is completely powered by solar energy – meaning that you pay power companies absolutely nothing!

 

There are other financial aspects to take into consideration if you’re thinking about converting to solar energy. Some power companies will buy any surplus energy your system generates but which you yourselves do not use.

 

Once your renewable energy system is in place, you will in effect, be your own power company.

Solar systems can definitely save you money. The real question is, how much exactly? Well, that figure is based on a number of factors such as your exact location, your roof, your power bill, size of the system and several other factors. The fact is, every building and location is different. The fastest and most accurate way to determine exactly how much you can save, and how much it’s going to cost you, is to get a quote from Sunshine Solar.

 

Energy Buy Back

 

New Zealand currently has no set policy to regulate the buy back of power from solar energy creators. Each retailer sets their own policy and there is no government of this.
Comparisons are always in your best interest. As well as comparing retailers buy back rates you are best also to consider their retails rates for your area. The best retailer for you will depend on factors such as how much power your setup produces and how much you are likely to be able to send back to the retailer.

Heat Pumps

Heat Pump 

Heat_pumpsHeat pump systems for heating your water are much more efficient than traditional electric or gas water heaters. They only use energy to “move” the heat but do not create heat. Heat pumps use the same technology to heat water as is used to heat rooms. A well designed and installed system uses less energy than standard electric cylinders.

Heat pump water heaters are not dependant on receiving hours of sunlight and so can work in places that aren’t good for solar water heaters –say the south facing side of your home. Some heat pump water heater models take advantage of the cheaper electricity night rates some power providers have. Some heat pump water heating systems can also give you ‘central heating’. They do this by pumping warm water from the hot water tank around a system of underfloor heating pipes.

Things to keep in mind:

  • Generally, the hotter the outside air the better the heat pump runs. Heat pump water heaters tend to work best in areas with average air temperatures above about 7° Celsius.
  • If you live in a colder part of the country, some consideration is required as not all systems as designed to work at low temperatures. If the heat pump won’t operate in colder temperatures, then the system may rely on the standard electric element so you won’t get the energy savings you’ve invested in and it may not be suitable for your location
  • The upfront cost of heat pump water heating is relatively expensive.
  • In a minority of cases you may need a building consent to install a heat pump water heater. Sunshine Solar can check with your council and advise.
  • There are two different types of heat pump water heater:
    • split systems and
    • all-in-one units.
  • Split systems have the compressor unit outside and the hot water tank generally inside although the tank can also be located outside the house separate from the compressor. In some cases you can use your existing hot water tank.
  • All-in-one units have the compressor and tank together and the whole system usually sits outside.

Sunshine Solar recommends the Bosch Compress 3000 which is an Air to Water heat pump water heater which was developed in Europe converting the same reliable technology used in refrigerators to extract heat from the air and transfer it into the water.

This heat pump reduces energy use by up to 65% compared to a conventional electric storage hot water system.

Operating down to -7°C the Compress 3000 provides you with energy efficient hot water even when it is freezing outside.

Compress 3000 Heat Pump

  • Highly efficient heat pump – reduces energy use by up to 65%
  • Smart Controls to take advantage of:
  • Cheaper overnight power prices
  • PV Solar energy generation systems
  • Noise Reduction Mode
  • Designed for easy and low-cost install and servicing
  • The heat pump operates from -7°C to 40°C, delivering energy efficient hot water even in colder climates

Split System Heat Pump vs Self Contained System

Once you’ve made the decision to go with a heat pump – the next question is: are you getting a split system heat pump or a self-contained heat pump? There are a few things that you should consider before you pick.

Structural Flexibility

One key feature that separates the two systems is that a split system heat pumphas the handling unit and heat exchange separated from the compressor and the outdoor exchanger. In simple terms it gives you the flexibility to install the system wherever you want to.Heat_pump_water_heater

Compartmentalized Cooling and Heating

Free-Delivery Split-Systems are great for families that have different cooling and heating preferences. This system has one outdoor unit and two or more indoor units. This system provides specific heating and cooling for each room with each room having its own thermostat.

Self Contained Heat Pumps

Self contained heat pumps, otherwise known as packaged heat pumps, allows both your compressor and heat exchangers to be located inside your home. Heating and cooling is done through ductwork.Self contained heat pumps are quick to be installed and when it comes to the costs, self contained heat pumps aren’t as pricey as the other systems mentioned.

A warm swimming pool year round?

Heating a swimming pool can be very expensive using standard pool heaters. Sunshine Solar has solar and heat pump technologies that can enable you to swim whenever you want and in a temperature that you choose. A seasonal solar pool heating system is by far the most cost effective way to heat your pool. If you and your family want to enjoy a warm pool throughout October to April an unglazed (or semi glazed) solar pool heating system is what you are after.  However, if you are wanting more consistent pool temperatures year round a pool heat pump system is what you need.

Solar Pool Heating Options

The most cost effective solar water heating system available is using low cost unglazed solar panels.Unglazed solar panel systems move and incrementally heat large volumes of pool water quickly as they do not utilize expensive heat exchangers.

Semi glazed and fully glazed pool heating panels are other options available is say your site does not have enough suitable north facing roof space to accommodate large solar arrays. These panels are great if you are wanting higher temperatures such as in hot tubs and spas.

Heat Pump Pool Heaters

You will find with heat pump pool heaters that they cost more than gas pool heaters. The payoff with this though is that typically heat pump pool heaters have much lower annual operating costs because of their higher efficiencies.  The lifespan of a heat pump pool heater (with typical maintenance) is typically longer than gas pool heaters and so you’ll save more money in the long run.

 

Combination Systems

Combined Systems

What is a combined system? Often these are referred to as Hybrid Solar systems and they combine the best from Combination_systemson-grid and off-grid solar systems. Hybrid Solar systems are less expensive than off-grid solar systems as they do not require a backup generator and the battery bank required can be significantly downsized.

Hybrid systems provide power to offset the grid power whenever the sun is shining and will even send your excess power back to the grid for credit for later use. These systems provide power for your critical loads when the power grid is down however do not expect these to provide power for all your loads since the cost and volume of the batteries would be prohibitive.

You can program these systems to consume power during off-peak hours or from your solar panels. You can therefore temporarily store whatever excess electricity you have from your solar panels in batteries, and put the excess on the utility grid at the time when you are paid the most for every kWh you onsell.

According to many renewable energy experts, a small “hybrid” electric system uses a combination of renewable generation sources (such as solar PV, wind turbine or micro-hydro), a battery bank, smart controller/inverter and a back-up and they offer several advantages over either single system.

 

Many hybrid systems are stand-alone systems, which operate “off-grid” — not connected to an electricity distribution system. For the times when neither the wind nor the solar system are producing, most hybrid systems provide power through batteries and/or an engine generator powered by conventional fuels, such as diesel. If the batteries run low, the engine generator can provide power and recharge the batteries.Battery banks are typically sized to supply the electric load for one to three days.

If you live in a remote area then considering a hybrid power system could be a good way to get your electricity needs met or, if there is simply no connection to an electricity network, combining micro-generation, control and storage technologies together can provide a stable system for you.

Connecting your rural property to the electricity network can be expensive – costing as much $25,000 per kilometre. So you don’t have to be far from the nearest electricity lines for a hybrid power system to be a better alternative.

Combination_solar_systemsAdding an engine generator makes the system more complex, but modern electronic controllers can operate these systems automatically. An engine generator can also reduce the size of the other components needed for the system. Keep in mind that the storage capacity must be large enough to supply electrical needs during non-charging periods.

The cost of installing and maintaining a hybrid power system can vary a lot – it depends on the combination of the components and the electricity output you need.

  • Middle-of-the-range systems, with either solar PV panels or a wind turbine as the primary energy source – usually cost $15,000 to $25,000.
  • If you are looking at a  micro-hydro based system – the set up costs usually range from $12,000 to $15,000, with 20% to 25% needing to be allowed for the batteries.
  • Inverters – can cost from $3,000 to over $10,000, depending on the size, quality and complexity. You can avoid using an inverter by using DC-powered appliances but they’re generally more expensive and the choice is limited.
  • Diesel or petrol-fuelled generator – will cost $4,000 to $12,000 to buy and install. The size of the generator depends on the amount of electricity you need, the size of the battery bank and the renewable energy sources available to you.

Consent requirements

In many cases you’ll need either a building or resource consent (or both) for your micro-generation system.

This will depend on what type of system you are installing. For example you may find that your local council has height restrictions on wind turbine towers, and you might need regional council consent if you are going to require damming or converting a stream on your property.

 

 

Photovoltaic

Which type of solar system is for you?

Photovoltaic (PV) Solar

A photovoltaic (PV) solar system is comprised of solar panels, racks for putting the panels on your roof, electrical wiring, and an inverter. From sunrise to sunset, the solar panels generate electricity (DC) which is sent to your inverter. The inverter converts the DC electricity into alternating current (AC), which is a type of electricity required for household use. The AC power is delivered directly to your home’s main board for use by you and your family.
PV systems range from small, rooftop-mounted or building-integrated systems with capacities from a few to several tens of kilowatts, to large utility-scale power stations of hundreds of megawatts. Most PV systems are grid-connected, while off-grid or stand-alone (hybrid) systems only account for a small portion of the market.
PV systems are silent and have no moving parts or environmental emissions. They are a mature technology used for mainstream electricity generation. A rooftop system recoups the invested energy for its manufacturing and installation within 0.7 to 2 years and produces about 95 percent of net clean renewable energy over a 30-year service lifetime.
Due to the popularity of PV systems the prices have rapidly declined in recent years. However, they vary by market and the size of the system.

On-Grid Solar

On-grid means your solar system is tied to your local power provider’s system. These systems must be connected to the grid to function.  This is what most homes will use because you are then covered if your system under or over-produces energy. If you are producing more energy with your solar panels or system than you are using, the excess energy is sent to your grid’s power company, allowing you to build credit that you can cash out with at the end of the year, in a process called net metering. Being on-grid means that you don’t have the added outlay in purchasing a battery back-up system to store any excess energy which can be very expensive..

These are the simplest systems and the most cost effective to install.  These systems will pay for themselves by offsetting power bills in 3-8 yrs. These systems however do not provide power during a grid outage.
They are cost effective enough to pay for themselves and put money in your pocket long term.  If you want to reduce your power bill and your carbon footprint then this type of system is a good choice.

Off-Grid Solar

Being off-grid means you are not connected in any way to your grid’s power system or utility company. This is appealing because you are 100% self-sustaining your energy use. If the power grid goes down or, if you have chosen not to be on the grid – these systems allow you to store your solar power in batteries for use.   Off-Grid systems require a lot more specialized equipment to function that is costlier and more complex to install.
A battery bank will typically need replacing in 5-15 years, depending on quality, sizing and how often you use them. There are issues that arise if your battery bank is too small or too large. Too small and it may be discharged at a low level too often – shortening its life. If it is too large, it will cost you more and it may not fully charge regularly – shortening its life. Sunshine Solar will help you choose the right sized battery bank for your needs. We also provide a maintenance programme to help you keep your batteries in good working condition for longer.
There is more initial outlay required as these systems are complex to install.
Given the additional specialized equipment required and the fact that it requires some complex installation, you can expect an off-grid system to cost around four times as much to install per watt and to require ongoing maintenance outlays.

Inverters

It is all about compatibility. A solar inverter converts the electricity from your solar panels (DC, or direct current) into power (AC, or alternating current) that can be used by the appliances in your house. Solar panels can’t create AC power by themselves; they need the helping hand of a solar inverter.
Solar inverters are around 95% efficient, so you only have about a 5% loss of power when the electricity is converted from DC to AC

Are there different types of inverters?

There are central inverters which make the conversion from DC to AC from a box in one location – usually your fuse box in the garage or hallway. There is a newer type of solar inverter, called a “Microinverter” and these work directly and independently under each solar panel. These are a little more expensive and take more time to install.
Advanced inverters, or “smart inverters,” allow for two-way communication between the inverter and the electrical utility. This can help balance supply and demand either automatically or via remote communication with utility operators. Allowing utilities to have this insight into (and possible control of) supply and demand allows them to reduce costs, ensure grid stability, and reduce the likelihood of power outages.
