Project Overview
Measurable energy savings
from a tailored commercial system
Tokai Manor is achieving significant energy savings through a tailored solar PV and battery system installed by InPower. During a 12-month assessment period, the facility reduced the amount of electricity it needed to purchase from the City of Cape Town by 25%.
Instead of facing an estimated annual direct electricity cost of almost R3.77 million, Tokai Manor paid approximately R2.83 million for electricity purchased from the City.

THE CHALLENGE
A high-consumption
facility needing greater
cost control
Tokai Manor requires a reliable and cost-effective electricity supply throughout the year. Without an alternative energy solution, all electricity consumed would have needed to be purchased from the City of Cape Town.
Based on the applicable electricity tariff, this would have resulted in an estimated annual direct energy cost of approximately R3.77 million.
- Reduce the amount of electricity purchased from the grid
- Lower annual electricity costs
- Provide greater control over future energy expenses
- Improve the property’s long-term energy resilience

Long-term Value
Reducing exposure to rising electricity costs
Tokai Manor’s results demonstrate the measurable financial value that a properly designed commercial solar and battery system can deliver.
Generate more electricity on-site, purchase less from the municipality and gain greater control over long-term energy costs.
The result is a lower annual electricity bill, less reliance on the grid and improved energy cost predictability.
