In order to lower the CAPEX, one may try to lower the costs of cabling and choose low-end connectors, which are about 30 percent cheaper than high-end connectors.

However, one needs to keep in mind that connectors make up only about 30 % of the total initial costs.

The usage of low-end connectors involves many risks and can have a substantial impact on the financial yield over time.

Consequences:
• High risk for connector failures
• Performance losses, higher PPM-rates, and downtimes of module
• High service/maintenance and spare part costs for repairing
• Hotspots and fire in a PV system and reconstruction costs
• High costs for legal disputes due to undefined liabilities
