Renewable energy · rental & installation

A fixed power bill,
while Eskom keeps
climbing.

We fund, install and maintain your solar system. You pay one fixed monthly rental, designed to land below your rising grid bill, and at the end of the term the system is yours.

01 · The Problem

Electricity is the
fastest-rising cost
on your balance sheet.

South African grid tariffs have more than tripled since 2010, and keep climbing at roughly 8 to 12% a year. It is a cost you cannot control, and every year of waiting widens the gap.

Grid tariff, indexed to 2010 More than tripled · still climbing 8 to 12% a year
02 · The Mechanism

Your rental holds flat.
The grid keeps climbing.

Solar on a GridAsset rental locks your energy cost as a single fixed figure. While the grid compounds every year, your rental does not move. The widening gap between the two is your saving, every month, for the life of the term.

YOUR SAVING YEAR 1 YEAR 5 YEAR 10

The grid

Compounds, 8 to 12% a year.

Every increase stacks on the last. What you pay today is the cheapest it will ever be.

Your rental

Fixed, 0% escalation.

One agreed figure, locked for the full term. No tariff, no per-unit meter games, no surprises.

The gap

Is your saving.

It widens every year, and at the end of the term the system is yours, generating for free.

03 · What We Do

We finance it. We run it.

One fixed monthly rental with zero escalation for the full term, while grid tariffs keep climbing. The system becomes yours at the end.

04 · How It Works

From first call to
switched on.

STEP 1

Site assessment

Free and without obligation. We model your building, your usage profile and your current tariff.

STEP 2

Fixed proposal

System spec, fixed monthly rental and projected saving. Real numbers, on paper.

STEP 3

One agreement

A single rental contract. No finance application, no bond over the property.

STEP 4

Installation

Fully funded and project-managed by GridAsset, end to end.

STEP 5

Switch on

Your rental stays fixed while tariffs climb. The gap is your saving, every month.

The 5+5 term, in plain terms
Years 1 to 5

We own and run it.

A fixed monthly rental. GridAsset owns, operates and maintains the system, and carries the performance risk.

Years 6 to 10

Still fixed. Still ours to run.

The rental continues at the same fixed figure, 0% escalation. Nothing changes for you, and your saving keeps widening against the grid.

End of the term

It becomes yours.

Ownership of the system transfers to you. It keeps generating, rental-free, for the rest of its working life.

05 · Rental vs PPA

Own the asset. Don't
just rent the power.

Power Purchase Agreement

With a PPA, a provider installs the system and sells you the electricity it produces at a per-kWh tariff that escalates every year. The provider keeps the asset. You are still buying power, on a long contract, and at the end you own nothing.

GridAsset Rental

With our rental you pay a fixed rand figure, not a moving tariff, with 0% escalation. We carry the capital, maintenance and performance risk, and at the end of the term the system becomes yours.

Why rental wins

You end up owning it.

Payments build towards an asset on your balance sheet, not a provider's.

Cost certainty.

A flat rand figure is easy to budget. A PPA tariff still rises with the grid and with your usage.

No take-or-pay exposure.

No minimum-consumption clauses penalising you for using less.

One simple agreement.

Not a metered electricity contract for the next ten to twenty years.

06 · Products & Partners

Tier-1 hardware.
One accountable party.

We carry the system for years, so we only install equipment we trust. Design, hardware, installation, compliance and monitoring all run through one accountable team, never a chain of subcontractors pointing at each other.

01

Panels

Tier-1 modules · high-efficiency monocrystalline

We specify only Tier-1 monocrystalline panels, backed by long-dated product and linear-performance warranties, so the array keeps producing well past the rental term.

02

Inverters + Storage

Hybrid systems · inverters + LiFePO4 storage

Hybrid inverters paired with lithium-iron-phosphate battery storage and fast backup switchover, for clean, stable power and seamless protection against outages.

03

Engineering · EPC

Accredited EPC · design, install, commission

Vetted engineering, procurement and construction partners design each system to the site, manage installation and commissioning, and sign off every job to South African standard.

07 · The Arrangement

The risk sits on our side
of the table.

What we carry

The capital

Every rand of hardware and installation.

The performance

If the system underdelivers, that is our problem.

Maintenance & monitoring

For the full term, at our cost.

What stays with you

Your building

No bond, no security over the property.

Your savings

The gap between rental and grid spend is yours.

Your operations

Nothing changes in the day-to-day.

The system, eventually

It transfers to you at the end of the term.

08 · Where We Fit

Built for operations
that run on power.

If electricity sits in your top five costs, the model works.

10 · The Financial Case

The saving is just
the beginning.

Beyond a lower monthly cost, solar on a GridAsset rental works hard on your balance sheet, your tax position and the value of your property.

Tax

Tax efficient.

Your rental is an operating expense, and solar assets qualify for accelerated tax depreciation under Section 12B. Worth a conversation with your accountant.

Balance Sheet

Off your books.

No capital outlay and no debt raised. The system sits off your balance sheet for the term, then transfers to you as an owned asset.

Property

Worth more.

Solar-fitted commercial buildings carry a 3 to 5% value uplift. The same asset that cuts your bill lifts what your property is worth.

Certainty

A real hedge.

A fixed cost, locked against a grid that compounds 8 to 12% a year. The kind of certainty you can actually budget around.
