Why Spare Parts Are Cheap?
✅ Advantages of Modular Structure
When a tube breaks, only that tube is replaced, not the entire system.
You can perform most part replacements yourself - no service needed.
58mm and 47mm are standard sizes, suitable for every brand.
High-quality parts last 10-15 years, frequent replacement is not required.
Wholesale Price Advantage
As Wholesale Solar Energy, we offer all spare parts from the manufacturer at the most affordable prices. Even a single part at wholesale price!
Get Price via WhatsAppFrequently Asked Questions
How much are spare part prices?
Prices vary according to the part and market conditions. Contact us on WhatsApp for current pricing.
Is heat pipe sold separately?
Yes, copper heat pipes are sold individually. If the glass tube is intact, only the heat pipe can be replaced.
Is shipping by cargo available?
Shipment by cargo is risky for glass tubes as they are fragile. Hand delivery from our Istanbul Beylikdüzü warehouse is recommended. Small parts (gaskets, valves, etc.) can be sent by cargo.
Which parts are replaced most often?
The most frequently replaced parts are silicone gaskets (every 3-5 years), vacuum tubes (in case of damage), safety valve, and anode rod.
