Nelson-Tasman - Lightforce Solar

Lightforce Solar are committed to serving the Nelson-Tasman and wider New Zealand market with tailored solar solutions.

Why the Region Leads New Zealand

If you’ve compared solar quotes in Nelson-Tasman and noticed they all look the same, that’s worth paying attention to. Many installers rely on generic templates that assume average sunlight, average roofs, and average demand. Nelson-Tasman’s conditions are anything but average.

The Nelson-Tasman region averages 2,472 sunshine hours per year, the highest of any region in New Zealand, which puts it in a category of its own for solar energy generation potential. While most NZ cities average between 1,800 and 2,100 hours, Nelson-Tasman consistently leads the country.

January alone delivers approximately 260–270 hours of sunshine, and even the shorter winter months retain enough solar resources to make year-round generation viable.

Lightforce Solar designs systems specifically for Nelson-Tasman conditions: coastal humidity, salt air exposure, seasonal variation from long summer days to shorter winter light, varying roof orientations, and shading from surrounding hills and terrain. The region’s moderate climate means panels benefit from cooler operating temperatures that improve efficiency, but coastal weather patterns and low winter sun angles still need to be addressed through careful site assessment.

A well-designed Nelson-Tasman solar system is built around your actual site, not a generic template. Lightforce Solar’s process focuses on maximising the energy your roof can generate year-round, improving how much of that generation you use directly at home, and removing wasted spend on oversized or unnecessary equipment.

Nelson-Tasman homeowners and businesses who go solar with Lightforce gain the ability to generate clean, renewable energy on-site, reducing their draw from the national grid and lowering their exposure to ongoing electricity price increases. For those thinking about long-term sustainability, solar also supports a meaningful reduction in household emissions without major lifestyle changes.

Why Lightforce Solar for Nelson-Tasman

Our Nelson-Tasman solar approach is built around the specifics of your property, not a standard quote:

Designed From Real Energy Use

We review your actual energy usage and before recommending a system size.

Lightforce Solar gives Nelson-Tasman homeowners and businesses a genuinely engineered solar solution.

Built for Local’s Coastal Climate

We design for the region’s seasonal variations, coastal conditions, roof orientations, and terrain shading patterns.

Smart Battery Storage

We size storage around your actual evening consumption in Nelson-Tasman, not a one-size-fits-all template.

Ready for Future Upgrades

We design systems with future EV chargers, heat pumps, electric hot water, and expanding household demand in mind.

Installed by Trusted Solar Experts

Our team focuses on long-term generation, quality installation, regional building consent knowledge, not rushed projects.

Instead of forcing you into a one-size-fits-all solar solution, Lightforce Solar gives you a properly engineered path.

How Our Nelson-Tasman Solar Process Works

Getting the right solar system doesn’t need to be complicated. It needs to be accurate.

01

Site and Energy Assessment

We begin with your last 12 months of power bills. This gives us a clear picture of how your household or business actually consumes electricity. We assess:

02

Custom System Design

With your usage and site data in hand, we build your system design using satellite imagery, roof modelling, and shading analysis.

This ensures you get the right balance of performance, energy independence, and long-term value.

03

Installation and Ongoing Support

Our in-house Nelson-Tasman installation team will install and manage your solar project.

After installation, all Lightforce systems include real-time monitoring via the mySigen app so you can track generation and flag any performance issues early.

The Lightforce Solar Difference in Nelson-Tasman

Designing a system that performs reliably for 25 years in Nelson-Tasman’s specific coastal and climatic conditions is where genuine expertise makes the difference.

Custom Design, Not Template Pricing

We design around your usage, roof, shade, & future plans.

Nelson-Tasman regional knowledge

We factor in sunlight, weather, terrain, and council demands.

In-House Accountability

One local team manages the project from consultation through installation

Proven Results in Nelson-Tasman

Nelson-Tasman’s exceptional solar resource, combined with careful system design and accurate matching of generation to real household or business demand, consistently delivers strong results. Homeowners in the region can expect annual returns on their solar investment of 7–14%, and many systems achieve payback in around 6–8 years.

Solar energy can reduce annual power bills from $3,000 to under $1,000 for well-matched systems. A 14-panel system can generate up to $2,680 per year in bill savings and export credits. In optimal conditions, payback can be achieved in as little as 6.5 years.

Nelson-Tasman customers often want to know the system performs through winter, that bills stay low year-round, and that the investment still makes sense as heating, hot water, and EV charging demand grows. That’s where design quality makes the difference.

24 Panels 2 battery 10kw inverter set up, a few Hiccups but they redeemed themselves. Had been looking at solar for a couple of years, with some savings and alot of research we were able to start the project. Sales: 5 stars We had a few online meetings with Jordan along with calls to discuss what we wanted. We gathered quotes from a number of companies. The big stand out during this process was Jordan not being pushy, he was real with his advice. Although we had quotes from others he never once bad mouthed them even tho some others tried to over sell us. He was able to do up a package that meet our needs with what we actually needed and not some massive system that we didnt need. This was the highlight of the process for us, Thanks Jordan!!! Between sales and install: 3.5 stars Between us signing the contract and install, we found communication was alittle slower. I followed up with Jordan who was able to get the answers for us. Pre install: 3 stars Because we are outside the Auckland area where they have their own crew we had contractors. Install was meant to start the monday so emailed to confirm on the friday to find out the contractors had pulled the pin. They then needed to fine another contractor to do the job and send all the equipment to them. We then got another few dates for install which were canceled and delayed due to the other jobs the contractors had. It was fair to say we werent happy and were considering pulling the pin on the project altogether this was escalated to a national manager. Received a call by the national manager after hours while he was heading home, he gave his assurance that we would have the project finished that week. The install: 5 Stars The redemption of the project!! Contractors from TEL turned up, install began. These guys were amazing and pulling some big hours to get the job done, here about 7:30am and not leaving until 6pm. They were friendly and hard working, keeping me informed every step of the way and seeking my opinion for where things went. Ive seen a few other places that have had solar installed. the way they have done it at my place is alot more tidy and clean than those ive seen. Would I recommend Lightforce? In a nutshell yes they have great knowledge of what they sell, the sales team didnt try upsell to something I didnt need and the install team was amazing. The system: SigEnergy 10W inverter and Gateway 2x 9kw SigEnergy batteries 24x Trina Vertex S 505W Panels Once the system went live we had non stop rain and cloud, the system still managed to grab 13.5KW of energy between 9am and 5pm which I was impressed with considering the conditions. Although I cant give a 5 star review because of the hiccups Jordan from sales and their contractors TEL made the experience a more positive one than negative. The solar is coming in and we are happy with the product so far.

The team at Lightforce Solar made the whole journey easy. Everything was done in a timely manner and fully explained to me. Everyone was friendly, helpful and available to answer any questions. I felt the price was reasonable and I am now very pleased with my new solar system.

Very happy. Great communication at every step of the process, they took care of all the paperwork, the team on the ground was very professional, tidy and friendly. Had my first power bill and it made a huge dent and the difference almost covered the finance costs, and that is in May and in Wellington. The GoodWe inverter that came with the 9 kW system allows you to drill into power usage by minute, let's you track individual household appliances and of course those clouds.

Lightforce installed an Enphase system with microinverters for us, which was ideal given the shading from our chimney and neighbouring trees. The sales rep who visited was excellent — very knowledgeable, answered all our questions, and provided a very detailed quote. The installation, however, was the disappointing part. I was expecting the job to take around three days, but it ended up taking the better part of a month. A design issue meant the system had to be reduced by one panel, and it often felt like the team had multiple installs running at once. I also had to follow up several times to get updates. That said, I’m very happy with the finished product. The system looks tidy on the roof and is securely mounted. We’ve had a couple of major storms since installation, and I was genuinely worried the panels might lift — but they held firm. Because the system uses microinverters, each panel runs independently, and the only hardware on the wall is a small, tidy box next to the switchboard. The app is simple and works well, and I’ve recently discovered that smart‑home platforms like Home Assistant can pull data from it, which is a bonus. In terms of performance, our highest power bill so far has been $90 going into winter, down from around $300. Part of that saving also comes from removing natural gas and installing a hot‑water heat pump, but solar has clearly made a big difference. With energy prices rising so quickly, installing solar feels like a no‑brainer. I was on the fence about giving 3 or 4 stars just purely on the install experience but will give 4 as the benefit outweighs the frustration

I’ve had a fantastic experience with Lightforce Solar from start to finish. At the outset of the project, I contacted three different solar companies, and Lightforce was the only one who responded, which immediately set them apart. What really stood out was their communication – they genuinely listened to what I needed and approached everything in a thoughtful and caring way. At every stage of the process, I felt heard and well supported, which made a big difference. The installation team were equally impressive. They were polite, respectful of the space, and kept everything clean and tidy while they worked. It made the whole experience feel seamless and stress free. The system itself has been excellent and is now covering 100% of my power needs, which is exactly what I was hoping for. The app that comes with the system and battery has been incredibly helpful as well. It’s given me clear insight into my energy usage and has helped me understand and reduce my power consumption quite dramatically. Overall, I couldn’t be happier with the outcome and would highly recommend Lightforce Solar to anyone considering making the switch.

We’ve had a great experience with Lightforce Solar. They really helped us by tailoring a solution that matched our lifestyle, and the comms was great throughout. Really good price and choice of battery, panels etc. Really impressed with the personal touch - Ryan checked in to make sure we knew how to work everything (and gave us some great tips) and was a pleasure to deal with. Enjoying the new found freedom of being off the grid!!! Would happily recommend LS to anyone looking at solar!

We reached a point where we needed to up our eco credentials as a B&B/Lodge. We've been pushing the eco-luxury angle, but we're relatively remote and not many players in the market would engage. Lightforce Solar did! From the first conversation there was great comms on how the process would work. There was no pressure at any point. The quote was well within tolerance of other prices we saw, for what we consider superior technology. We made changes to the quote at the point of choosing to move forward and there was a no hassles approach. It was simple and seamless. Given our remoteness there was risk on both sides, but by using online video tech it was possible for me to walk around the property describing what I wanted in terms of installation. I'd like to think I'm pretty savvy about the construction and potential of the house. We waited just very slightly longer than the proposed time, but, the dates actually worked to our advantage (end of season) and made it easy to get involved and support the team. The installation team were first class, they listened, and educated. We got, what we think is, the perfect build. It's early days and late autumn as I type. It's been live for less than one week and it's rained pretty much every day. But we've seen some real potential, with around 70% production compared to capacity (at times). The batteries are taking the load off our grid supply and allowing us to charge over night. Basically, it's been a first class experience from first call through to installation. I highly recommend this company, and we will be adding to our 'kit' and we'll be back in touch with them when we do.

Can't say enough good things about Lightforce Solar. Chose Lightforce over others as they listened to me and helped design a system perfect for me and my situation ... definitely not an off the shelf system that everyone gets. Most notable was the attention to details. Everything is very tidy which I appreciate. Total price very fair and in line with what I expected. Recommended to a friend who now has a solar system also thanks to Lightforce. His first comment to me after installation was how neat and tidy the installation was. As a builder he notices things like this. And remember, your installer will be your go to in case of a warranty claim so you want to feel comfortable with them. With Lightforce I do. If you want a great system that works without issue immediately, make sure you get a Lightforce quote. Thanks Lightforce.

Light Force Nelson provided the best quote(not the cheapest not the dearest ) that fitted my needs. The team were fantastic from first contact to the finished install. Great equipment through sigenergy and design of the install was brilliant and compact. The addition of a EV charger with the ability to charge from solar just puts a bigger smile on my face. The app is easy to use and very informative. Highly recommend you see these guys for your solar needs.

Great experience with Lightforce Solar. From the initial contact and consultation, Jevan took the time to walk through the different options and assess the house to recommend what would work best. The installation team also did a great job working around some terrible weather while keeping everything moving smoothly. Highly professional and easy to deal with from start to finish.

We did a LOT of research on solar and solar companies before choosing Lightforce and so glad we did. The initial meeting with Steve was really positive, he gave us even more insight and did not try to pressurise us in anyway. The guys who came to fit the system over 2.5 days were professional, courteous, and hardworking - they were in fact some of the best tradies we've come across. It's not a cliche when people say they wish they'd done it sooner - I wish we'd done it sooner! Just do it!

FREQUENTLY ASKED QUESTIONS

Read the information below to find out answers to our most commonly asked questions.

Solar panels perform exceptionally well in Nelson-Tasman. With 2,472 sunshine hours per year – the highest of any New Zealand region – the area offers an outstanding solar resource for both residential and commercial systems.

Coastal weather brings both advantages and considerations. Panels benefit from natural air cooling that improves efficiency, and regular rainfall keeps surfaces clean with minimal effort. Components do need to be rated for humidity and salt air exposure, which is something our team accounts for in every Nelson-Tasman installation.

A well-designed Nelson-Tasman solar system typically achieves payback within 6–8 years, depending on system cost, how much solar generation you consume on-site, electricity rates, roof conditions, and whether battery storage is included. In optimal conditions, payback can be as short as 6.5 years.

Nelson-Tasman’s high sunshine hours and moderate electricity costs combine to make the region one of the strongest in New Zealand for solar ROI. Annual returns of 7–14% are achievable for well-designed systems.

Not necessarily, but batteries can add meaningful value if you want evening power, outage protection, or greater energy independence.

Lightforce Solar’s preferred battery is the Sigenergy SigenStor, available in 6 kWh and 9 kWh options and stackable up to 48 kWh for larger homes. For households where battery storage isn’t the right fit yet, a hot water cylinder timer is a practical lower-cost way to store excess daytime solar energy. Battery prices continue to fall, and systems designed today can be made future-ready for battery add-ons when the economics improve further.

Nelson-Tasman’s coastal environment is well suited to solar when the right equipment is specified. Corrosion-resistant mounting systems and properly sealed electrical components are standard in our Nelson-Tasman installations, protecting your system from salt air and humidity over the long term.

Regular rainfall helps maintain panel efficiency naturally, and our annual inspection recommendation means any early issues are caught before they affect generation. Our local team understands these coastal requirements from direct experience and builds them into every installation from the start.
