In Sri Lanka’s fast-evolving industrial landscape, many factories still rely on diesel generators to keep operations running during power outages. But here’s the hard truth: diesel is draining more than just your fuel tanks – it’s draining your profits. If you’re searching for solar panel companies in Sri Lanka, Roofmart Solar stands out as one of the most reliable and cost-effective choices. Let’s explore why switching from diesel to solar is not just a smart move, but a necessary one.
Hidden costs of diesel generators
Diesel generators seem convenient at first, but when you dig deeper, the numbers tell a different story. Aside from the upfront purchase price, ongoing expenses are quietly increasing.
1. Fuel costs that never stop rising
Diesel prices fluctuate – but mostly upwards.
A medium-sized generator can consume up to 10-15 liters of diesel per hour.
In a year, the cost of fuel runs into lakhs of rupees.
2. Maintenance and wear and tear
Regular oil changes, filter changes and engine overhaul are mandatory.
Skilled technicians and spare parts are not cheap.
The depreciation increases for every hour of use of the generator – which reduces the resale value.
3. Environmental impact
Diesel exhaust contains harmful carbon and nitrogen oxides.
Regulatory costs and carbon taxes are expected to increase in Sri Lanka.
The company’s carbon footprint affects the brand image and international partnerships.
Solar vs Diesel: Comparing Real Costs
Let’s see how diesel generators stack up against solar power systems in real factory settings.
| Feature | Diesel Generators | Solar Power (Roofmart Solar) |
| Initial Investment | Low to Moderate | Moderate, but with long-term ROI |
| Operating Cost | Very High (fuel + maintenance) | Almost Zero |
| Lifespan | 5–10 years | 25+ years |
| Noise & Pollution | High | None |
| Energy Independence | None (depends on fuel) | 100% renewable |
| Government Incentives | Limited | Available for solar adoption |
| Payback Period | Never truly pays back | 3–5 years average |
Why is solar energy more useful for Sri Lanka’s factories?
Sri Lanka receives plenty of sunshine throughout the year, making it one of the best regions for solar energy production. Here’s why it’s the ideal solution for industries:
1. Fixed and predictable costs
With solar energy, you invest once and enjoy free electricity for decades. No more worries about rising diesel prices or unexpected electricity bills.
2. State aid and net metering
Sri Lanka’s net metering policy allows you to send excess electricity back to the national grid – further reducing costs.
3. Quick return
Most commercial solar systems pay for themselves within 3-5 years, after which the energy is practically free.
4. Sustainable brand image
Companies operating in clean energy enjoy a good reputation among customers and international partners.
5. Hassle-free maintenance
With a high-quality installation from Roofmart Solar, your system will run trouble-free with minimal maintenance for decades.
