A GreenMatters engineer securing rooftop solar panels

Expertise

Designed, built and kept running.

We bring an engineering perspective to the roof space, the electricity demand and the commercial decision behind solar, from the first load study to a system that is still performing years later.

01

Grid tied solar.

Commercial rooftop PV, engineered to your building’s load and tariff, then procured and installed by our own team. It generates power on your roof and uses it on site through the working day, cutting the electricity you buy and your exposure to every tariff increase.

  • Sized to your building’s load and tariff
  • Power used on site through the working day
  • Procured and installed by our own team

Tariff arbitrage: charge the battery when power is cheap, use it when power is expensive. Illustrative daily profile.

02

Hybrid & storage.

Where a site has to run through grid interruptions, we add lithium storage and, where it fits, generator integration. The system carries critical loads through load shedding and outages. The daily saving of solar, plus resilience the grid can’t guarantee.

  • Daytime: solar powers the building and charges the battery
  • Night and outages: the battery keeps you running
  • Grid support: used only when needed

03

Monitoring & O&M.

Solar only pays if it keeps performing. Every site we run is monitored, with operating manuals and a maintenance programme that catches faults and holds yield up over the life of the system on our installations and on systems built by others.

  • Every site we run is monitored
  • Operating manuals and a maintenance programme

How a project runs

From the first load study to years of returns.

01

Load study

We start with your building’s demand and tariff, so the system is sized to what you actually use.

02

Design

3D layouts, shading analysis and structural approval from our own engineers.

03

Build

Tier 1 equipment, procured and installed by our own team.

04

Monitor & maintain

Every site is monitored and maintained so it keeps performing for years.
