Home / C&I underperformance

Commercial & industrial solar underperformance

When a C&I array looks fine from the roof but savings are missing, SolarMD runs an independent performance check and turns the evidence into a clear decision.

What we deliver

A structured performance check: production vs expectation, data quality, and plain-English next steps. Installation and repairs stay with licensed contractors.

Example: expected vs actual

Sample data, illustrative

What a performance check can show for one year of output. Illustrative sample for a fictional 250 kWp hospital rooftop system in Mindanao, March 2025 to February 2026.

Expected (weather-adjusted)312 MWh
Actual (metered)248 MWh
Gap−64 MWh (about 21%)

Month by month

MWh per month (1 MWh = 1,000 kWh). The gap widened mid-year, when faults went unnoticed.

Where the 64 MWh went

Estimated loss by cause. Losses add up to the full gap.

  1. Expected312 MWh
  2. String faultstwo west-roof strings offline (blown fuses)−18 MWh
  3. Soilingdirty panels on the low-tilt west roof−14 MWh
  4. Inverter downtimetrips and restarts on two inverters−9 MWh
  5. Monitoring gapsfaults went unnoticed while the portal was offline for 30 days−8 MWh
  6. Shadingafternoon shade on part of the array−5 MWh
  7. Other / unexplainedincluding peak-sun clipping the proposal did not model−10 MWh
  8. Actual248 MWh

Bar scale starts at 200 MWh so the smaller losses stay visible.

What it means: about a fifth of this year’s expected solar energy never arrived. Most of the gap traces to a few fixable causes, not a failed system.

What SolarMD does: we find the cause, size each loss and rank the fixes by impact. Repairs and cleaning are carried out by qualified partners; we then check the data to confirm each fix worked.

Check your site for Zero Capex solarRequest a performance check

SolarMD funds, owns and looks after solar for C&I sites under a 15- to 25-year Zero Capex PPA, and also offers independent performance checks. When we make our own PPA offer, we say so. Savings are dependent on your rooftop size.

Solar at ₱0 upfront for your site

Commercial and industrial businesses with a monthly electricity bill of ₱1.2 million and up (about 100,000 kWh a month), including hospitals, can apply for a 15- to 25-year SolarMD solar PPA. For ₱1.2M+ monthly bills, ask about the PPA-RES Combo.

Savings are dependent on your rooftop size. SolarMD is not a bank, not the EPC and not an RES. Every offer depends on a site assessment, a credit review and a signed contract.
