More and more businesses are turning to solar power to reduce energy costs and improve sustainability performance. By generating electricity on-site, you can:
TotalEnergies ENEOS provides a fully integrated commercial & industrial solar solution so you can realise these savings with minimal risk and complexity:
We finance, design, build and operate the solar PV system, so you avoid upfront investment.
You pay a competitive rate for the solar energy produced, helping you manage long-term energy costs.
From site analysis and engineering to installation, monitoring and maintenance, everything is managed for you.
Under the Power Purchase Agreement, you pay only for the actual kilowatt-hours generated by your on-site solar panels.
The solar savings calculator estimates your potential savings by factoring in your roof size, your current average grid tariff, and your country of operation to project how much solar electricity could replace your existing grid consumption. It then calculates your system capacity, expected first-year generation in MWh, and projects savings over a 35-year lifetime. The estimate also includes an indication of CO₂ emissions avoided, giving you both a financial and an environmental picture of going solar. It’s worth noting that the estimate is indicative and non-binding, as actual savings will vary based on your specific site conditions.
To use the solar savings calculator accurately, you will need to provide your country, your property address, the size of your roof in square metres, and your current average grid tariff per kWh. You will also need to indicate whether your company owns the building, and if not, how many years remain on your lease. You can also input an annual tariff change rate to project how rising grid prices might affect your long-term savings. Having a recent electricity bill on hand is recommended, as it will contain most of this information.
Some companies have saved millions of dollars and thousands of tons of CO₂ emissions each year by switching to solar. Savings begin from the very first energy bill, as each kilowatt-hour generated by the on-site solar system directly offsets more expensive daytime grid electricity. These monthly reductions compound over the 15 to 25-year lifetime of the solar panels, lowering the average cost per kWh over time. The exact amount varies by facility size, energy consumption, local tariff rates, and roof area available.
Switching to solar with TotalEnergies ENEOS requires zero capital expenditure from your business, as the company finances, builds, owns, and operates the solar panel system on your site. Under a long-term Power Purchase Agreement (PPA), you simply pay a competitive rate only for the electricity your system generates, which is typically lower than your daytime grid rate. All operations and maintenance are also handled by TotalEnergies ENEOS, including monitoring, cleaning, repairs, and performance optimisation, so there are no hidden operational costs either. This means capital that would have gone into energy infrastructure can remain focused on your core business.
Actual savings may be higher or lower depending on your building’s electricity load, location, weather and climate conditions, and the direction, pitch, or angle of your roof, as well as any shading or obstruction of your property. Additional preparatory expenses such as electrical works, cabling, or roof repairs may also be required to make your property system-ready, which could reduce the overall savings realised. On the environmental side, CO₂ reduction results are directly tied to how much grid electricity is displaced by solar generation, which in turn depends on system size, self-consumption rate, and the carbon intensity of the local grid. A site visit and technical study by the TotalEnergies ENEOS team is the best way to get a precise, property-specific projection.
