Capacity expansion
Additional modules and the electrical work to support them, checked against service and interconnection limits first.

Solar Upgrade & Repowering Projects
Arrays age, households grow, and the original installer is often long gone. We take on systems somebody else built: adding capacity for an EV or a heat pump, replacing inverters that have reached end of life, retrofitting monitoring so faults surface early, and diagnosing the gradual underperformance that owners usually do not notice until we measure it.
Owner-side project advisory, coordination and administration from planning through closeout. Gridless organizes the people, information, documentation, budgets and decisions, while appropriately licensed contractors and professionals remain responsible for regulated work.

Free energy analysis & consultation
Before you spend anything, we measure the property and rank every improvement by payback. The analysis and the consultation are both free, with no obligation to go ahead.

What we organize
What Gridless helps organize on your project
Inverter replacement
String and micro-inverter replacement when the original reaches end of life, typically after ten to fifteen years.
Monitoring retrofit
Module-level electronics that turn a silent array into one that reports faults the week they occur.
Battery retrofit
AC-coupled storage added to an existing array without replacing what already works.
Performance diagnostics
IV curve tracing, thermal imaging and string testing to find the exact cause of lost output.
Orphaned system adoption
We take over management of systems whose original installer has gone, including tracing what warranty cover still survives and who now holds it.
How we work
A sequence that keeps the project honest
- 01
Measure
Actual output is compared against modelled expectation.
- 02
Diagnose
Thermal and electrical testing isolates the real fault.
- 03
Plan
Repair, expansion and modernisation options priced side by side.
- 04
Upgrade
Work completed with minimal array downtime.
- 05
Verify
Post-work production confirms the gain was real.

Common questions
Something not covered here? Ask us directly - we would rather answer it properly than have you guess.
Ask a questionMy production dropped. What causes that?
Most often a failed optimiser or micro-inverter, a tripped string, soiling, or new shading from tree growth. Occasionally it is module degradation. A diagnostic visit by a licensed technician settles it rather than guesswork.
Can I add panels to an old system?
Usually, though it depends on inverter headroom, service capacity and your interconnection agreement. Where mixing old and new modules is a problem, a separate string with its own inverter is often the cleaner answer.
Can you take on a system another company installed?
Routinely. A large share of the programmes we manage are on arrays installed by companies that are no longer trading.

How licensed work is handled
Gridless Global provides owner-side advisory, project-administration and coordination services. Gridless does not perform regulated trade or professional work. Construction, installation, engineering and other services requiring licensure are separately performed by appropriately licensed independent professionals responsible for their own work. The scope Gridless can offer varies by jurisdiction.
