The Early EfÞ cient architecture increases the Internal Rate of Return thanks to:

• Initial cost investment savings of the BoS (civil work, transformation stations, cabling, installation)

• Revenues increase (improved efÞ ciency)

• Operating expenses decrease. (no dedicated maintenance team)

• An increase of the inverter life duration.

A Set is the smallest brick of the system. It is made of PV modules, a 10 kWp inverters and 3 meters DC cables (4 mm²) to connect a string to the inverter through a DC breaker.

A Block is made of 10 Sets each connected together thanks to 30 meters of 400 V cables up to a 400V protection unit and an Early Solar Transformer (EST) 100 kVA buried transformer (400 V / 6,6 kV).

A Line is a 6,6 kV cables with different sections. It ga-thers the energy from 10 Blocks. It connects buried transformers up to a single transformation station. In the station, are 6,6 kV Mega Solar Protection Unit (MSPU) & 20 kV protections and a heading transfor-mer 6,6 kV / 20 kV.

Plug & Play a 10 MWp power plant

Energy transport is at 6,6 kV as Early as possible. It improves the plot Þ lling ratio. From 250 kWp and whatever the plant power, only one single transformation station is needed.No costly trenches for 20 kV cables but basic 6,6 kV cables underground installation. Power Line Communication can be a reliable and inex-pensive solution.

The products are evenly distributed in a 10 MWp power plant

Thanks to the 6,6 kV energy transport and its reduced current, the total cable length is reduced as well as the cable sections. It allows easy power plant construction for :• stretched Þ elds (along roads, …)• Þ elds on a slope• split Þ elds

This very innovative energy distribution system for a photovoltaic power plant with medium voltage of 6.6 kV aims to increase the voltage as Early as possible, decreasing the current and therefore the cable losses, to be as EfÞ cient as possible. Thanks to its unique architecture, the efÞ ciency is not very sensitive to the Þ eld pattern.In addition, it reduces mismatch losses and there is no consumption for inverter watchdogs, air vent, and air conditioning.

Decrease the CAPEX - Thanks to the reliable and inexpensive technology to transport the power at 6.6 kV, the

Early EfÞ cient system saves the over costs of the 20 kV lines: deeper trenches, metal

shields. There are no DC cables to bury and most of the 400 VAC cables are installed

in the solar mounting system. The trenches and cables lengths are shorter. The cables

sections are much smaller and need less raw materials. Therefore, the cables costs are

cheaper as their installations because the turrets / reels can be either smaller or getting

a longer cable length.

- The Early EfÞ cient system reduces drastically the cost of the transformation stations as

most of the transformers are buried in the ground.

- This system allows to consider inexpensive Þ elds (split, stretch, slope) and to increase the plot Þ lling ratio

while its efÞ ciency is not sensitive to Þ eld pattern thanks to its unique architecture .

- The Power Line Communication system avoid the costs of the wires for communication and their installation

while the reliability is as good as by wires and much better than radio communications.

Increase the Revenues

- The Early EfÞ cient system increases the efÞ ciency as it reduces the cable and the mismatch losses. There is

no consumption for inverter watchdogs, air vent, and air conditioning.

- Thanks to the electrical architecture, only small segments are affected in case of few faulty equipments

remaining the rest of the production available.

Reduce the OPEX - Smart power plant monitoring aims to propose no dedicated maintenance team in the

power plants. A subcontractor, within 50 kms, could operate the maintenance.

The monitoring alert system sends a SMS / Email to the maintenance staff. This one

goes on a website to locate the faulty equipment and to evaluate the consequences.

According to the diagnosis, the electrician goes to the power plant to either clean, check,

repair or change the material.

- Thanks to On the shelve equipments, times for changes are quick and the inventories

linked to the equipments in warehouse are narrowed.

Improve the life time and the reliability - All the equipments are highly maintainable as the wearing components can be changed.

- The Mega Solar Protection Units allow to disconnect all the inverters during the night even their watchdogs.

Therefore all the capacitors (weakest component within an inverter) life times are saved.

- Even if this system looks very innovative to transport the energy in a photovoltaic power plant, the 6,6 kV is a

basic standard used for many decades in public lighting while the Power Carrier Communication is common

to communicate with reliability along numerous kilometers of cables to supply airport runaway lighting or in

public lighting.
