What is the 120 rule for solar panels?

The 120% rule for solar, based on the National Electrical Code (NEC), is a safety guideline for load-side solar interconnections, stating that the sum of your main breaker rating plus the solar breaker's rating (multiplied by 125% for continuous solar output) shouldn't exceed 120% of your main electrical panel's busbar rating, preventing busbar overload, overheating, and potential fire hazards by limiting combined grid and solar power flow. This rule ensures safety by allowing a 20% buffer for the busbar to handle both utility and solar power simultaneously, often resulting in limitations on the size of the solar system you can add without upgrades.

The Formula:
(Main Breaker Amps + (Solar Breaker Amps * 1.25)) ≤ (Busbar Rating * 1.20).
Example:
For a 200A panel with a 200A main breaker on a 200A busbar:
(200A + (Solar Breaker * 1.25)) ≤ (200A * 1.20)
(200A + (Solar Breaker * 1.25)) ≤ 240A
(Solar Breaker * 1.25) ≤ 40A
Solar Breaker ≤ 32A (meaning you'd typically install a 30A breaker).
Busbar Placement:
To allow for the 120% calculation, the solar breaker must be at the opposite end of the busbar from the main breaker.

What are the different types of solar connectors?

Solar connectors link solar panels and components, with the MC4 connector being the dominant industry standard for its secure, waterproof, and easy-to-use design, but other types like MC3 (older), T4, Tyco SolarLok, Radox, and Amphenol also exist for specific applications, handling varying currents and serving different system needs (e.g., large-scale, portable).

This video provides a brief overview of what MC4 solar connectors are:

MC4 (Multi-Contact, 4mm): The most popular, standard connector for residential and commercial solar, featuring a reliable locking mechanism for weather protection (IP67 rated).
MC3: An older, predecessor to the MC4, used in earlier systems but less common now.
T4: Often used by specific manufacturers like Canadian Solar, similar to MC4 but designed for their panels.
Tyco SolarLok: Another reliable option for secure connections.
Radox: Popular, especially in European markets, known for durability.
Amphenol H4: Designed for higher current and voltage applications, robust for heavy-duty use.
XT60: Frequently used for connecting portable solar setups to power stations or generators.
