Solar System Components Installed by UTL Solar
Below are the major components used in this 5kW on-grid solar installation by UTL Solar.
TOPCon Bifacial DCR Solar Panel (525 Watt)
The system used 10 high-efficiency TOPCon DCR solar panels of 525 W each which offered a total installed capacity of around 5.25 kW. These DCR-compliant panels were eligible for government subsidy under the PM Surya Ghar scheme and come with a 27-year performance warranty.
Grid-tied Solar Inverter
A 5.3 kW grid-tied inverter was installed to convert the DC electricity generated by the solar panels into usable AC power. It helps manage the power flow efficiently, supports net metering, and comes with a 10-year warranty for long-term reliability.
Protection Systems and Safety Setup
To ensure safe and reliable system performance, multiple layers of electrical protection were integrated into the installation.
Electrical Protection Components
- DC Distribution Box (DCDB) for safe control of DC power flow
- AC Distribution Box (ACDB) for secure management of AC output
Surge & Lightning Protection
Lightning arrester installed to protect against voltage surges and it safeguards the system during extreme weather conditions
Earthing System
- Triple earthing system implemented for enhanced safety and it ensures safe dissipation of excess electrical current into the ground.
