On-Grid Solar Heating
2kWp Grid Tie Solar System – From $7,200.00 Incl. GST
Finance terms are 5 years @ 9.95% interest
2kWp Grid Tie Solar System – fully installed
The 2kWp grid connected system can produce between 2,600 – 3,000kWh of energy per year depending on your location. If you are an average energy user this system may reduce your energy by approximately 1/4 to 1/3, maybe more if you are a low energy user.
This system includes highly efficient Tier 1 solar PV panels, an Austrian made inverter with built in WiFi monitoring, a roof mounting system with engineer’s certification, the balance of components required for installation and labour to install the system.
- 8 x 250watt DAQO solar PV modules (13.04m2)
- 2kW Fronius inverter
- WiFi monitoring
- Flat mounting frame
- Installation
- Expected annual generation 2,600 – 3,000kWh
2kWp Case Study
In November 2012 we installed a 2kWp grid tie solar system for Mr Jonas in Nelson. Mr Jonas is a relatively low energy user as he also has solar thermal installed on his house.
The graph on the right demonstrates the daily energy generation the system has produced, which works out at approximately 3,000kWh for 2013.
For the year of 2013 Mr Jonas ended up in credit for $80 with his energy retailer and so he has no power bill.

3kWp Grid Tie Solar System – fully installed
The 3kWp grid connected system can produce between 3,900 – 4,500kWh of energy per year depending on your location. If you are an average energy user this system may half your energy bill, maybe more if you are a low energy user.
This system includes highly efficient Tier 1 solar PV panels, an Austrian made inverter with built in WiFi monitoring, a roof mounting system with engineer’s certification, the balance of components required for installation and labour to install the system.
- 12 x 250watt DAQO PV solar modules (19.56m2)
- 3kW Fronius inverter
- WiFi monitoring
- Flat mounting frame
- Installation
- Expected annual generation 3,900 – 4,500kWh
3.12kWp Case Study
In September 2011 we installed a 3kWp grid tie solar system for Mr Yockney in Blenheim. Mr Yockney is a fairly average energy user and his solar system has more than halved his power bill.
The graph on the right demonstrates the daily energy generation the system has produced, which works out at approximately 4,900kWh for 2012. You will note that this is a fair amount more than we say the system can produce as we would rather under specify the expected production than under specify it.
4kWp Grid Tie Solar System – From $12,000.00 Incl. GST
Finance terms are 5 years @ 9.95% interest
4kWp Grid Tie Solar System – fully installed
The 4kWp grid connected system can produce between 5,200 – 6,000kWh of energy per year depending on your location. If you are an average energy user this system may reduce your energy bill by approximately 2/3 – 3/4, maybe more if you are a low energy user.
This system includes highly efficient Tier 1 solar PV panels, an Austrian made inverter with built in WiFi monitoring, a roof mounting system with engineer’s certification, the balance of components required for installation and labour to install the system.
- 16 x 250watt DAQO PV solar modules (26.08m2)
- 4kW Fronius inverter
- WiFi monitoring
- Flat mounting frame
- Installation
- Expected annual generation 5,200 – 6,000kWh
4kWp Case Study
In April 2013 we installed a 4kWp grid tie solar system for Mr Sims in Taupo. Mr Sims is a fairly high energy user as he runs his home as a B&B as well. The idea was to install a 4kWp system and then if it worked well he would install another 3.5kWp system at a later date on another roof. The first 4kWp system over halved his energy bill and now with the second system installed he no longer has a power bill.
The graph on the right demonstrates the daily energy generation the system has produced, which works out at approximately 5,475kWh for 2013.
5kWp Grid Tie Solar System – From $14,500.00 Incl. GST
Finance terms are 5 years @ 9.95% interest
5kWp Grid Tie Solar System – fully installed
The 5kWp grid connected system can produce between 6,500 – 7,540kWh of energy per year depending on your location. If you are an average energy user this system may eliminate your energy bill or come very close to it, maybe more if you are a low energy user.
This system includes highly efficient Tier 1 solar PV panels, an Austrian made inverter with built in WiFi monitoring, a roof mounting system with engineer’s certification, the balance of components required for installation and labour to install the system.

- 20 x 250watt DAQO PV solar modules (32.6m2)
- 5kW Fronius inverter
- WiFi monitoring
- Flat mounting frame
- Installation
- Expected annual generation 6,500 – 7,540kWh
5kWp Case Study
In June 2013 we installed a 5kWp grid tie solar system for Mrs Rogers in Christchurch. Mrs Rogers is a fairly average energy user and so her solar system has almost eliminated her energy bill. Mrs Rogers is considering adding another two panels to her system to get rid of the small amount of energy remaining which she is paying for from her energy retailer however she is very happy with what the system has achieved.
The graph on the right demonstrates the daily energy generation the system has produced, which works out at approximately 7,560kWh for 2013.
Commercial Grid Connected Solar Systems – From $22000 + GST
Solar PV Designed For Business
Solar PV works great for many business types, especially those which use power during the day as you can make greater use of the power produced on site. By lessening the amount of electricity exported to the grid, you directly offset the need to buy power. This makes for large savings, fast pay back periods and a high ROI.
Standard Packages
Our commercial business packages start at 10kWp, and we can design and build systems as large as you require. Packages include the design and analysis, supply & installation of equipment, and commissioning. Monitoring systems are also provided so that you can closely monitor your investment in solar energy.

Typical Applications
This example is of a 10kWp grid connected PV Solar system installed on a Warehouse and Logistics facility. This facility operates mainly throughout the day and therefore the bulk of the energy generated is consumed on site.
This example is of a 10kWp grid connected PV Solar system on an Adventure Lodge. While the facility is not being used or has low occupancy, excess energy is sold to the grid which builds credit when the energy retailer for higher occupancy, high demand periods.
This example is of a 50kWp grid connected PV Solar system on a large Wheel & Tyre Warehouse. This operations runs mainly throughout the day and therefore the bulk of the energy generated is consumed on site.
This example is of a 20kWp grid connected PV Solar system on a School. Schools are perfect for solar as the bulk of their energy is consumed during the day while the children are on site. Children can also study the solar generation as part of their tuition.
This example is of an 80kWp grid connected PV Solar system on a Dairy Farm. Dairy farmers consume a lot of energy in the dairy shed heating water, pumping and for the cooling of milk each day. The bulk of the energy consumed in the dairy shed is throughout the day, which is perfect for solar generation.
This example is of a very la
rge grid connected PV Solar system on a Vineyard, which is consuming a lot of energy producing wine.As well as heavily reducing their energy costs, they have also dramatically reduced their carbon footprint, increasing the marketability of their product.
This example is of a 10kWp grid connected PV Solar system on a Greenhouse.
Energy is used to irrigate the plants, maintain the correct temperatures within the Greenhouse and for harvesting of the crops. The bulk of this energy is used throughout the day, which is perfect for solar generation.
