About Energy

Energy collected from the sun is the cleanest and most sustainable source of energy we know. Its use relieves us from the consumption of exhaustible fossil fuels and does not pollute while reducing considerably the emission of carbon dioxide.

Enphase Micro-Inverters:

At the heart of Enphase system is a powerful technology. Solar panels may be on top, but it’s the inverter that does all the real work. Choosing an inverter technology is the most critical decision you will make while going solar.

Enphase micro-inverters make use of the highest quality components, cutting edge technology and advanced monitoring software to create tailored solar energy solutions for Homeowners and commercial projects.

Features

  • Higher production and best Savings

Enphase microinverters are proven to produce more energy than other technologies. Microinverters operate independently, so each panel performs to its fullest. One shaded or dirty panel won't affect the rest of the system. Burst technology lets microinverters produce more at dawn, dusk, and in low-light conditions, for a longer solar day.

  • Reliable

Enphase micro-inverters function independently and are inherently more reliable: as there is no single point of failure in a microinverter system.

  • Safety

Enphase are well known for meeting the requirement of safety norms as they Micro-inverters provides for an all A/C current at a lower voltage compared to traditional inverters with a high voltage of DC current.

  • Flexibility

The Enphase System is flexible, so you can design a system to fit today's budget and energy needs, and expand it later as your needs evolve

  • Higher Production Efficiency

Enphase tolerates shading better than conventional inverters. Secondly, their independency of micro-inverters maintains operation of your system although part of panels is affected by shading, dirt or leaves. With micro-inverters, only the individual panel is affected (by either shade and debris), while the other panels perform to their maximum efficiency. With string panels, if one panel is affected, the other panels operates at the same diminished capacity.

Technical Specifications

  • MPPT Range: 27 - 39 V
  • 96.5% CEC efficiency
  • 96.5% Peak Efficiency
  • Integrated Ground, eliminating the need for a copper grounding wire or WEEB
  • CSA Listed per UL 1741/IEEE1547

How it Works?

Step 1: The solar panels on your roof absorb sunshine in the form Direct Current (DC) power. Fixed beneath each panel, a Micro-inverter converts the DC power into Alternative Current (AC), the form of electricity your home can use.

Step 2: The Envoy is the brain of the system, gathering data from your micro-inverters and delivering it to the Enlighten software. It communicates in the other direction also allowing to pinpoint any issue remotely and delivering updates to the micro-inverters.

Step 3:My Enlighten is your window into your home energy. It turns Envoy’s data into an easy to use interface that lets you track your system’s production and see your home energy usage.

Photovoltaic Kit and SSDG Net-Metering Scheme for Residential requirement

The installation of Photovoltaic Kit for residential requirement need to abide by the SSDG Net-Metering Scheme set by the CEB. The Net-Metering scheme is established as per table below:

Energy Imported
(kWh)

All Installations will be equipped with one production meter and one import/export meter. Prosumers are advised to verify regularly the meters so as to ensure consistency with statement of accounts.

If a Prosumer take more electricity from the CEB than she/he has sent into the grid, the quantity imported in excess of the quantity exported will first be reduced by any quantity of energy already in balance, if any, before the final energy charge is raised.
 

Sizing of the Photovoltaic Kit

The size of the Photovoltaic Kit for residential installation is as from 1 KW till 3.5 KW as established by the CEB as per table below:

Average Monthly
Consumption (kWh)

For example, for 3.5 KWp, with an average of 4 hours adequate sunshine per day; the estimated monthly production of the Kit per will be 420 Kwh.

Photovoltaic Project and MSDG Net-Metering Scheme for Commercial requirement

For installation of On Grid Photovoltaic system for commercial requirement; the project proposal should meet the criteria of the MSDG Net-Metering Scheme of the CEB.

The size of the Photovoltaic system is determined by the Formula set below by the MSDG Scheme:

The size of the individual RE system shall be determined by the formula given hereunder.

Where,
C is the periodic (monthly) electricity consumption (kWh) over a full year prior to the installation of the RE system or as shall be agreed by both parties. 

RE_Capacity is the installed capacity in kilowatt-peak DC of the renewable energy system.

m is for period (1 to 12) or as shall be agreed by both parties.

CUF is the average Capacity Utilisation Factor, taken as 18% for solar PV generation in Mauritius. The CUF for other RE technologies shall be subject for discussion. 

8760 is the total number of hours in a year

30% is the factor satisfying one of the conditions of the Scheme

Note:At the end of each year, provided meter readings data for at least 12 billing periods is available, CEB will make necessary adjustment to the CUF using actual measured data provided by the Prosumer. The measured data submitted shall be validated with CEB's meter readings. A continuous monitoring will be effected so as to confirm the actual power output of the RE system.

Prosumers who are already registered under an existing CEB RE Scheme can apply for the CEB MSDG Net-Metering Scheme I, provided they terminate their existing Connection Agreement with the CEB.
