Your Options

Two ways to go solar with Gridstone

Whether you want zero upfront cost or full ownership from day one — we've structured both properly.

Most Popular

Fixed Monthly Lease

Gridstone funds and owns the system. You pay a fixed monthly amount lower than your current Eskom bill. We maintain it for 10 years — then it's yours, automatically.

  • ✓ Zero deposit — no capital required
  • ✓ Fixed monthly payment — not linked to Eskom tariff increases
  • ✓ All maintenance and repairs included — no callout fees
  • ✓ Live system monitoring included
  • ✓ Automatic ownership transfer at end of year 10
  • ✓ Buyout option available from year 5 at pre-agreed price
Best for: Homeowners who want immediate savings without tying up capital.
Full Ownership

Cash Purchase

Buy the system outright. You own it from installation day, keep 100% of the savings, and after payback you have free electricity for the remaining life of the panels.

  • ✓ Full ownership from day one
  • ✓ 100% of savings go directly to you
  • ✓ Typical payback period: 5–8 years
  • ✓ 25-year panel performance warranty
  • ✓ Increases the value of your property
  • ✓ Optional ongoing monitoring & maintenance plan
Best for: Homeowners with capital who want maximum long-term return.

FAQ

What homeowners ask us

Straight answers. If something isn't here, ask us directly.

On the fixed monthly lease, no. Gridstone funds 100% of the system. There is no deposit, no installation fee, and no design cost. You only start paying your fixed monthly lease once the system is live and generating power. For a cash purchase, you pay the agreed system cost upfront and own it from day one.
On the lease, Gridstone owns the system and carries all maintenance responsibility. If the inverter fails, panels underperform, or anything needs attention — that's our cost, not yours. There are no callout fees and no surprise invoices. We monitor the system daily, so we usually spot a fault before you do.
The lease transfers to the new owner along with the property. Most buyers see this as a positive — they're inheriting a home with lower electricity running costs already built in. We'll engage with your attorney and the buyer if needed. We've structured the agreement so it doesn't complicate a standard property transfer.
During the day, when the sun is up, most grid-tied systems continue generating even during load shedding — depending on your inverter and municipality setup. After dark, a grid-tied system without battery storage relies on Eskom. If full backup is important to you, we'll structure that conversation separately. We won't oversell the standard package.
It's possible, but it requires body corporate or trustees' approval. We've navigated this process before and can provide the right documentation to present to your body corporate. Whether it's approved depends on your specific complex rules — we'll tell you upfront if it looks like a problem.
Yes. From year 5 onwards, you have the right to buy the system at a pre-agreed price written into your contract before you sign. That number is transparent upfront — no negotiation after the fact. Most clients keep the lease running because it's comfortable, but the option is always there.
Ownership transfers to you automatically. No balloon payment. No buyout fee. No extra paperwork. The system is simply yours. A quality solar panel has a useful life of 25–30 years, so you'll typically have 15+ years of free daytime electricity ahead of you. That's where the real long-term value sits.
