Here’s what the locals had to say...

Rob Brough


Guy and Nikki of Harrisons Solar in Marlborough/Nelson have been wonderful to deal with. I explained what I was looking for and oh boy, did they deliver! I followed Guy's advice, having them install 24 high-end LG panels (I decided to "over-panel"), two Tesla Powerwalls and a Fronius inverter. Wow! I am charging the batteries by mid morning, running the house and sending 30+ kWh to the grid every day and it's still a couple of weeks before longer summer days. It's a great feeling to know that I have some independence from the grid! The installation was done on time and to a very high standard. I couldn't be more pleased and would recommend them to anyone.

Guy and Nikki Jacobson who own the Harrisons Solar franchise for the top of the South Island installed a 15kw system on our Blueberry packing shed to meet the increasing demand of electricity required for our orchard expansion. We choose to go with the Harrisons business based on the level of expertise and experience in this field. We have not been disappointed, from the first consult with Guy through to the clear and honest quoting and performance of the system we have never looked back.

Its been a absolute asset to our business, Guy and Nikki where extremely clear, based on our location that the system would work very well on our packhouse due to our power usage through the summer/harvest months but when I ask the company about installing a system on our house for winter usage Guy was very up front and said it would not work.

We really appreciate the professionalism of their company and cannot speak highly enough of the way they conduct their business for the franchise, and them as a hard working honest team.

The entire process was seamless and professional and is saving us money! Yay!

Rai Valley Area School

Rai Valley

Rai Valley Area School chose Harrisons Blenheim to manage and provide their Solar Installation, because Guy and Nikki are so passionate about what they do and being local it meant the school would have long term local support. The school’s installation was a complex one – also providing an emergency backup system supported by a Tesla Powerwall to support our Rural Community should it ever be cut off from the national grid for any length of time.

Guy and Nikki worked closely with the school and delivered the project on time and within budget. They have continued to be available with any questions and support to show how effective the system is regarding savings and energy efficiency within the school.

I really recommend Guy and Nikki. They were patient and understanding with my limited knowledge of solar panels and took the time to really discuss product options, etc. Installation was a breeze and the follow up service has been great. From all of us at Motupipi School, thank you!

Guy and Nikki Jacobson of Harrison’s Solar in Blenheim were fantastic to deal with. We now have our system all hooked up and operating. They took care of everything required for the install. Guy has been great to deal with and I’d highly recommend him to anyone looking to install solar. Siraz and his team did a great job with the install and were good to deal with. Overall a very good experience for Kathrin and I having chosen Harrison’s to supply of solar needs

Having just had our solar system installed I would like to congratulate Guy and Nikki Jacobson from Harrisons Energy Tasman for running a very efficient business. The whole process from initial consultation and being kept in the loop on time frames for various different things that had to happen along the way. There efficiency with dealing with power providers, meter installation, inspectors and the necessary certification is all very seamless and is absolutely stress free. Basically, if they said something was going to happen in a certain timeframe it did! Their choice of installers is also spot on. They arrived when they said they would, worked efficiently and left absolutely no rubbish or packaging behind. I personally love dealing with efficient and successful businesses like this and would not hesitate to recommend them to anyone thinking of installing solar.

The service from Harrisons has been great - initial contact was really informative about the operation of the solar system and the installation process was very smooth. Since then my system of 16 panels and battery has worked well (and kept me going through an extended powercut). What has been really appreciated is the follow-up service from Guy and Nikki who both have a genuine desire to ensure that the system continues to work as it should be and that I'm getting the best deal from the power company.

G’day Nikki and Guy

Many thanks for the wonderful service you provided us with your recent sale and installation of your Harrisons solar panel system to our Motueka house.

We really appreciated how prompt you were, how you kept us fully informed every step along the way and how pleasant everyone of your people have been to deal with.

Our system is up and running perfectly and we are looking forward to substantial electricity savings.

Kind regards,

Steve & Leallen


The decision to go with Harrisons was easy. After a couple of presentations from other vendors it was clear to us that Harrisons whilst not the cheapest had by far the best overall system and after sales backup. Their installers are great too, nothings a problem.

We initially had LG panels with optimisers mated to a solar edge inverter but a year later decided to add a battery. To anyone considering a Tesla battery they are amazing and somewhat addictive.

With a little management of your loads during the day it is possible particularly in summer to be 100% efficient 24hrs a day for months with Nelson sunshine. Everything going great. Pools at 28 degrees…bliss.

We couldn’t be happier and so pleased we chose Guy and Nikki at Harrisons

Brenna and Andrew


We are thrilled with our new solar panels from Harrison’s Energy Tasman. Guy was fantastic from day one, he showed such professionalism and expertise that made the process simple and efficient. Their service was second to none and through every process, they kept us informed and ensured we were happy and understood absolutely everything.

Together Guy and Nikki made the entire installation seamless and we truely appreciate their attention to detail. We follow our panels through an app on our phone that they walked us through and they continue to touch base with us to ensure any questions are answered.

Thanks Guy & Nikki!

My wife Leigh and I have been tracking the development of residential solar energy for over 20 years. Now retired and living on conservative investments, early this year (2019) we recognised our time to install a system in our Rapaura Blenheim home had come. Solar panel technology and cost had fallen considerably, grid power costs had risen consistently and alternative investment yields had fallen and forecasts suggested they would continue to do so. Backup battery technology and cost were anticipated to improve over the next few years. Fortunately we had recorded our power costs monthly over a three year period and therefore we could calculate potential financial payback and well as environmental social benefits.

We contacted several potential providers. We selected Guy Jacobson and his wife Nikki, Harrisonsons Energy Solutions Tasman . They gave us a very professional presentation of their products and the procedures involved. We wanted top line high wattage panels, a quiet inverter from a main line provider and a team of experienced installers and a competitive price. We sought references from others who had installations completed by Guy and Nikki. All were highly complimentary.

Their quotation was competitive. Not the lowest but given the quality of the products provided well worth the little bit extra.We selected LG NeON2 345W panels, SolarEdge PV inverter with SolarEdge Optimizer. All first line recognised products.

We cannot speak more highly of the installation crew. They tackled our Monier spanish concrete tiles perfectly with only one tile broken. They finished the installation within two days and left everything clean and tiedy. Their teamwork was exceptional.

With our system up and running we are going to achieve at least a 10% annual return on our funds invested.

As you can imagine we are very satisfied customers and know we are in good hands with Guy,Nikki and Harrisons
