Frequently Asked Questions

Is the REC TwinPeak2 Mono Series really discontinued?

Yes — REC has ended production of this model. The panel shown above is no longer manufactured. PES Supply stocks direct replacements and compatible equivalents that meet or exceed the original specifications.

Will the replacement panel be compatible with my existing system?

Our recommended replacements are matched to within ±5% of the original wattage and use standard MC4 connectors. For string inverter systems, verify the voltage/current window. For microinverter systems, confirm optimizer compatibility. Our team can verify your specific configuration — use the Material Request or Job Intake form above.

Do I need an adapter kit?

If the replacement panel uses different frame dimensions or connector types than your original REC panel, an adapter kit (clamps, cables, mounting hardware) may be required. We bundle these in our Complete Replacement Kit above.

What is the warranty on replacement panels?

Replacement panels carry the full manufacturer warranty (typically 12–25 year product warranty and 25–30 year performance warranty), whichever is greater than the original discontinued product's remaining coverage.

Can I buy these in bulk for a commercial project?

Yes. PES Supply offers pallet and container pricing for commercial and utility-scale projects. Use the RFQ form below for volume quotes.
