Solar design
Load analysis, yield modelling and engineering sized to your site and tariff.
ONGroup · Clean energy for industry
We design, supply and install solar and battery systems for industry, help arrange finance, train your team and offer ongoing maintenance and support. You own the system and the savings.
01What we do
Seven disciplines under one roof, so nothing gets lost between design, build and care.
Load analysis, yield modelling and engineering sized to your site and tariff.
Tier-1 modules, inverters, batteries and mounting, delivered to site.
Certified installation, grid connection and commissioning.
Batteries carry midday sun into the evening and through outages.
Monitoring, planned servicing and technical support to help keep your solar and battery system performing. Service agreements tailored to your site and operating needs.
We work with you and your lenders so savings can cover repayments.
We train your team in safe use and routine checks, with ongoing maintenance and technical support available through an agreed service plan.
02Maintenance & support
You focus on your business. We look after your system.
ON Group offers maintenance and support agreements for commercial and industrial solar and battery systems. Services can include performance monitoring, scheduled inspections, cleaning, fault investigation, warranty assistance and repair coordination.
We agree the support around your equipment, location and operating requirements, giving you one point of contact to coordinate ongoing care.
Include support with a new installation, or speak to us about an existing system. Each service proposal is tailored following an assessment.
Discuss maintenance and support
Enquiries about existing systems may concern equipment installed by ON Group or another provider. Suitability and service scope will be confirmed following assessment. Pricing, included work, response arrangements and coverage are confirmed in each individual proposal.
03A day with ON
Output climbs with the sun. The grid or generator still covers most of the morning load.
At midday solar covers the production line and the surplus charges the batteries.
As the sun sets, stored energy carries the evening shift instead of diesel.
Stored energy can keep critical loads running during outages. Tomorrow, the cycle repeats.
04The model
We design, supply and install your system, train your team in safe use and routine checks, and offer ongoing maintenance and technical support through an agreed service plan.
Site visit, bills and load profile, hour by hour.
System, storage, savings and funding in one proposal.
Supply, installation, grid connection and commissioning.
The system is yours. We train your team and offer ongoing support through an agreed service plan.
05Savings calculator
Indicative only: ~4.8 kWh/kWp/day yield, ~$650/kWp installed without storage, typical emission factors. A site survey gives the real numbers.

Industrial · 3-phase · Kolonnawa, Sri Lanka
First of a roll-out across all Methuli Industry premises. Every kWh generated is exported to the grid.
≈ 4,800 kWh per month
Commercial facility · Peliyagoda, Sri Lanka
Designed, supplied and commissioned by our team, with a payback of about 3.3 years.
≈ 2,400 kWh per month
Business premises · Nugegoda, Sri Lanka
Covers most of the lab’s daytime load and cuts its reliance on the grid.
≈ 1,800 kWh per month
07Scale
Same team, same standard, at every size.
Factory and warehouse roofs
Estates, plants and industrial land
Grid-connected projects in development
*Example: site using 80 MWh/month, 65% in daylight, replacing grid power.
08Emissions & carbon
With Vulnerable Planet we are developing indicative estimates of the emissions each project avoids, and exploring whether those savings could qualify for carbon credits.
