Why Solis and Deye Dominate the Philippine Market
Walk into any solar installation in the Philippines today and there's a very high chance the inverter is either a Solis or a Deye. These two brands have captured the mid-range Philippine market for good reasons: they're technically solid, competitively priced, and — critically — they have enough Philippine market presence that parts and support are actually available.
That last point matters more than most comparisons acknowledge. A Huawei inverter might outperform a Solis on paper, but if a fault develops and Huawei's Philippine support takes 3 months to process a warranty claim, the real-world value is very different.
Solis vs Deye: Side-by-Side
Solis — Strengths and Weaknesses
Strengths:
- Longer Philippine market presence — more installers are familiar with Solis configuration
- The Solis Cloud monitoring platform is mature, stable, and reliable
- Strong global track record; over 300GW of Solis inverters deployed worldwide
- Better resale value and recognizability when selling a property
Weaknesses:
- Slightly higher price vs Deye for comparable specs
- Some newer Solis models have had firmware update issues — check the specific model series your installer is using
Deye — Strengths and Weaknesses
Strengths:
- 10–15% lower price vs equivalent Solis — meaningful savings on a full system
- Excellent off-grid and parallel operation features for community/commercial use
- EV charging integration on newer models — forward-compatible as EVs grow in the Philippines
- Very active development pipeline — features update faster than Solis
Weaknesses:
- Shorter Philippine track record — newer brand, less field data locally
- Some early models had communication board issues; verify the firmware version is current before installation
- Philippine after-sales network is growing but still smaller than Solis
Price Comparison in the Philippines (2025)

*Philippine market pricing as of 2025. Prices include the inverter unit only; installation rates vary by installer.
Hidden cost to consider: The inverter itself is ₱25,000–₱75,000 of a ₱330,000–₱700,000 system. Saving ₱5,000 on an inverter is a 1–1.5% system cost difference. Choose based on support and track record — not purely on unit price.
Our Recommendation (SolarStream's Honest Take)
For most residential installations: either brand is an excellent choice
SolarStream installs both Solis and Deye hybrid inverters depending on system requirements and availability. For straightforward residential hybrid systems (3–10KW), both brands perform within acceptable tolerance of each other. We lean toward Solis for customers who prioritize maximum peace of mind and longer Philippine track record; we lean toward Deye for commercial and off-grid applications where its parallel operation and EV capabilities are genuinely useful — and for budget-conscious clients where the savings are meaningful.
The most important factor isn't which brand you choose — it's that your installer knows the brand they're installing, has the tools to configure and troubleshoot it, and can process a warranty claim locally if something goes wrong.
