Rising electricity costs affect your margins

Tanzanian businesses face a combination of pressures that grows heavier each year: TANESCO or ZECO tariffs keep rising, power outages disrupt operations and damage equipment, and clients and investors increasingly expect real sustainability commitments.

Which system fits your business

We design each system around when you use electricity and how much backup you need.

On-grid system

Your panels cover part of your daytime consumption, reducing what you draw from the grid. The most cost-effective option for businesses operating mainly during daylight hours.

Best for: offices, retail, schools

Hybrid system

Solar combined with battery storage, so critical operations keep running during outages.

Best for: hotels, clinics, restaurants and mixed-use facilities

Off-grid system

Full energy independence for locations without reliable grid access, replacing diesel generation.

Best for: safari lodges and remote facilities

Solar for your industry

Each industry has different consumption patterns and priorities, which shape how we design your system.

Hotels and safari lodges

Reliable power for guests, with less reliance on noisy diesel generators.

Offices and corporate

Lower operating costs and backup power for mission-critical systems.

Retail and shopping centres

Keep premises cool and lit without unpredictable electricity costs.

Healthcare and clinics

Reliable power for medical equipment and medication cold chains.

Schools and universities

Redirect energy savings into education, with a visible sustainability project on campus.
