What's a Tier 1 manufacturer?

Only 2% of solar manufacturers are Tier 1. This ranking means that the company is vertically integrated - they make the whole product. They have fully-automated production lines, not people hand-soldering. They invest heavily in R&D and they have been producing solar for more than five years.

What is the difference between mono-crystalline and poly-crystalline?

This relates to the manufacturing process at the wafer stage. They are the same product essentially, but they are made differently. Please see the efficiency FAQ.

What is a micro inverter and what is better?

Micro inverters are small inverters under each module, rather than a string inverter that does the whole system. There are pros and cons for both systems: Micro inverters are a good alternative in highly shade-impacted areas, but they are intolerant to heat and adding more components to a system can result in higher replacement costs.

Will I have power if the grid fails?

If there is no grid the solar will turn off. This is a safety feature of the inverter called 'anti-islanding' to prevent any electricity being back-fed that could cause harm to people working on an isolated grid. Hybrid inverters will work if the grid goes down.

What does solar module efficiency mean?

Solar module efficiency relates to the area available to get a certain amount of electricity and has nothing to do with how much power is generated. Different solar modules will produce different amounts of power in different environments and irradiance and temperature are factors that affect system performance and/or efficiency.

What does inverter efficiency mean?

Inverter efficiency is directly responsible for how much DC power from the modules is converted into AC electricity for your house, meaning the more efficient the inverter the more electricity you make.

01 NovFive good reasons to add Solar + Battery Storage to your home

1. Security – insure yourself against predicted electricity price rises by generating and using your own electricity.  Electricity prices have been increasing well above CPI for several years and this is unlikely to change in the foreseeable future.
