Solar Transformer, Get The Best Price
10-28 2025 | By:
As solar energy projects proliferate, “solar transformer” has become a key component in photovoltaics systems. But how do you get the best price without compromising quality? At ZTelec Yuguang, we deliver cost-effective solar transformer solutions that meet technical demands and budget constraints.
Understanding the solar transformer market
-
Solar transformers are specially designed for PV applications: stepping up inverter output voltage, handling frequent load fluctuations, high ambient temperatures, low maintenance.
-
Competitive pricing comes from large-scale production, mature supply chain, and simplified logistics—advantages that ZTelec Yuguang leverages as a direct manufacturer.
-
it’s essential to compare apples to apples: rated capacity, cooling method, losses, lifetime—cheap sticker price may hide higher losses or shorter life.

Comparison of transformer types & price-drivers
| Transformer Type | Typical Price Drivers | Efficiency / Maintenance Impact |
|---|---|---|
| Dry-Type Solar Transformer | Resin insulation, minimal oil handling | Lower fire risk, easier indoors install |
| Oil-Immersed Solar Transformer | Oil volume, radiator size, tapping equipment | Higher cooling efficiency outdoors |
| Pad-Mounted Liquid Filled | Enclosure, ease of installation, compact | Ideal for distributed solar sites |
Specification table – sample data
| Type | Rated Voltage (kV) | Rated Capacity (kVA) | Losses (No-Load / Load) | Cooling / Environment |
|---|---|---|---|---|
| Dry-Type | 0.69 → 10 / 20 | 100 – 1 600 | ≤0.4% / ≤1.0% | Air cooled, indoor |
| Oil-Immersed | 6 / 10 → 20 / 35 | 500 – 15 000 | ≤0.35% / ≤0.9% | Oil immersed, outdoor |
| Pad-Mounted Liquid Filled | 480 V → 12.47 / 13.2 kV | 100 – 3 000 | ≤0.5% / ≤1.1% | Enclosed outdoor friendly |
Note: Actual pricing depends on quantity, specifications and any brands like ABB/Schneider used in auxiliary components.

Real-world solar deployment
One ZTelec Yuguang oil-immersed transformer – 1 000 kVA, 10 kV → 20 kV – was deployed at a 5 MW PV plant in Uzbekistan. The unit was designed for high sun exposure, low ambient cooling, with special varnish for humidity resistance. Delivered with full testing certificates and installed in under 5 weeks.
(Custom integrations with Schneider switchgear was included, demonstrating value beyond base price.)
Distribution Transformer Models and Price Analysis
How to get the best price now
-
Provide your key parameters: voltage levels, capacity, environment (indoor/outdoor), brand preferences.
-
Ask for full losses data, lifetime maintenance schedule.
-
Compare “factory direct” vs. “imported middle-man” offers—ZTelec Yuguang gives you direct factory price.
-
Consider total cost of ownership: lower losses and maintenance may offset higher initial price.
