350 W
One generic whole-system scenario, not the RTX 4090 benchmark, which assumes 400 W for the GPU itself.[2]

Not the hype.
Can one person make money GPU-mining crypto in the Philippines, especially with solar? A practical decision brief built around electricity, actual cash-out, and the costs the profit rankings leave out.
Research snapshot: 18 October 2026 · Scenarios, not promised returns

The mission decision
There is a narrow test case.
Not a bankable yield.
At current Meralco residential rates, established GPU-mined coins in our RTX 3070 and RTX 4090 calculator checks generally lost money on electricity alone. A striking positive estimate came from the younger Pearl network, but its displayed revenue has not been proven through an actual pool payout, exchange sale, and peso withdrawal.[1][2][3]
For an individual, the defensible move is a small pilot with an existing or readily resalable GPU. Solar helps most when genuine daytime surplus would otherwise be curtailed. Buying a rig, panels, and a battery specifically to chase a one-day ranking is a different and much riskier proposal.
Go / no-go
Test one rig.
Sell a payout.
Then decide.
No payout-to-PHP proof = no investment-grade profit claim.

The cost floor
Start at the wall socket.
Meralco's October headline rate was ₱15.0615/kWh for a typical home using 200 kWh monthly. That is not a universal price for the miner's next kWh. Estimate the added bill from your actual baseline, including host PC, PSU losses, ventilation and air-conditioning.[4][5]
8.4 kWh
Per day. At an illustrative ₱17 per incremental grid kWh, electricity alone is about ₱143/day, before cooling.
₱0 ≠ free
Already-owned GPU or solar still has wear, resale value, and the opportunity to use that energy for the home or export it.
Solar is a routing decision
Where would that sunlight go instead?
Compare the next best use of each solar kWh. Meralco credits net-metered exports at the monthly blended generation cost, not the full retail price. The October blended export basis was ₱10.1412/kWh before other generation adjustments.[6][7]
If solar would run appliances, diverting it to a miner can make the household import grid power instead. Value it against the applicable marginal retail cost, not zero.
If already net-metered, mining forfeits export credits. In the 350 W, 10-hour example, 3.5 kWh of daytime use means roughly ₱35.49/day of foregone October credits, plus grid power at night.
If production would otherwise be wasted and you own the system already, daytime mining can have a low immediate energy opportunity cost. Confirm it is truly surplus after other household loads.
Solar does not power a 24-hour miner overnight without storage. In our example, 14 non-solar hours still draw 4.9 kWh from the grid. Batteries introduce capital, conversion losses and replacement risk.
A Philippine installer's measured sample averaged 1,298 kWh per installed kWp over 2025, about 3.56 kWh/kWp/day as an annual average, not a daily guarantee.[8] Published grid-tie package listings put 1.57 kWp at ₱142,250–₱173,750; this is a public seller price, not a dated site-specific quote.[9] Roof shading, permits, inverter, safety devices and export configuration must be priced before any mining payback claim.
The apparent comeback
The highest-paying coin is the highest-risk assumption.
On an 18 October WhatToMine snapshot using preset hashrates, preset GPU power and $0.239/kWh, Pearl's trailing-24-hour columns showed $2.20/day gross on an RTX 3070 and $10.04/day gross on an RTX 4090. The calculator's profit figures account for its assumed GPU electricity, not your entire operation.[1][2]
We checked the identity chain: WhatToMine's Pearl refers to the native proof-of-work Pearl Research coin associated with pearlresearch.ai and a PRL-USDT market. An unrelated token, Perle, also uses PRL. Verify the network and deposit address, never just the ticker.[3][10][11][12]
Visible trading activity is not a completed withdrawal. We have not mined, deposited, sold, or cashed out a Pearl payout. An exchange listing can change; a price or difficulty move can erase the modeled margin quickly.
Before scaling
Complete the cash loop
- Pool sends native rewards to your wallet.
- Exchange accepts the correct network deposit.
- A small order sells at an obtainable price.
- Proceeds withdraw and convert to PHP after fees.
Keep transaction hashes and actual net proceeds. If any step fails, the projected pesos are not revenue.
Mission simulator / local only
Run your own break-even.
Enter your measured wall draw, a realized peso/day gross revenue if available, and the hours covered by solar. This calculator makes simplified daily opportunity-cost comparisons. It does not fetch live coin prices, predict future payouts, or save your entries.

Illustrative straight-line recovery: (capex − resale) ÷ months ÷ 30. Cooling is added to grid kWh. If your cooling uses solar, or solar output is irregular, model the actual hourly data instead. Excludes repairs, taxes, financing, inverter/battery degradation, and changes in mining rewards.
Pilot protocol
Prove the operation before buying the fleet.
Use one GPU
Prefer equipment already owned, or readily resalable for another productive use. Measure whole-system watts with a plug-in meter.
Mine in a pool
Compare fees, payout thresholds and rejected shares. One GPU mining solo can wait unpredictably for a reward.
Log 7–14 days
Record power, solar allocation, cooling, uptime, coins paid and daily changes in network difficulty and coin price.
Sell a small payout
Test the full deposit, sale, withdrawal and peso conversion. Compare real receipts against the calculator's conservative break-even.
Stress the case
Repeat at higher grid cost, lower coin price, rising hashrate and hardware repairs. Stop if the result depends on one fleeting top rank.
Check the alternative
Compare mining with household solar savings or simply buying the crypto you want. Consult a Philippine CPA for recurring business registration and tax treatment.
