Photon Power

A Power-Hungry World

Ageing Grid, Exceeding Life Expectancy:

$17 Trillion (2013) Needed Globally Why Invest In Failing Centrally-Controlled Infrastructure?

Energy Delivery of The Future

Drivers Of Change

 Falling cost  Rate hikes – 28% by 2018 in B.C.  Grid parity – 75% in 18 months.

 B.C is already there !

 Incentives  Fossil fuels – Climate Change

How do Solar PV Modules Work?

Large Scale Commercial

T’Souke First Nation: Population 250. Plan to reduce energy consumption by 75% and then net zero.

 75 kW of solar

Small Scale Residential

3 kW (12 Panel) Grid Tie System

1 0 kW (40 panel) Grid Tie System


 Yearly Consumption Budget Replacement decision  Physical site analysis – sun exposure, obstructions, space, roof vs ground, stresses re wind, structural issues, visual impacts, neighbours, bylaws, security and other considerations  Determine system size, number of panels, wiring requirements, location.

 Coordinate the install, permits and inspections necessary to complete.

Traditional Systems

Microinverter System

Advantages Of Grid Tie Microinverters

 240 volt AC, not 600 volt DC  Lower installation cost  Partial shading not a problem  Redundancy—no system failure vs string inverters  Cost for system units on par with string inverters

Racking System With Microinverters

Panel Mount over Microinverter

Before installing PV, reduce consumption

Do we have enough Sunshine?

Look at Germany

Solar power works on cloudy days!

The small demonstration inverter, rated at 1100 Watts is putting out close to 50% capacity.

On a full-sized system (10 kW), this would be 4745 Watts.

That’s enough to run 47 100 Watt light bulbs at the same time.

To Battery or not to Battery

To Battery or not to Battery

 Costly, high maintenance, and cannot transfer power for more than a few days. Not enviro friendly.

 Use the Grid as a battery.

 Accounting shifts summer surplus to winter deficit.

Three Meter Options

 Analog: No credit for surplus  RF off: Reading fee  RF on: Automatic credit for surplus

The Fortis /B.C Hydro Tariff

 To qualify for net metering, a Grid Tie System must have an approved bi-directional (smart) meter installed.

 From The Fortis Net Metering Guidelines ervice/NetMeteringProgram/Docum  Section 3.1.5 "It is required that the

customer's facility be equipped with a bi directional meter (or a meter approved by a Fortis designer)

Photon Power

- GabEnergy A Non Profit Society

The purposes of the Society are to:  promote and facilitate the development of sustainable alternative energy sources for Gabriola;  conduct educational outreach for alternative energy projects;  build skills and expertise on Gabriola for alternative energy development; and  facilitate the provision of low cost infrastructure for alternative energy systems throughout British Columbia .


 Portal connecting buyers to the wholesaler – not resellers  Provide advice, coordinate ordering, shipment and delivery of system components.  To cover fixed costs, a five percent donation for above services is requested.

*Prices do not include shipping, GST, installation & donation.

The Economic Case - Austin Texas

Levelized Cost (LCOE) for Solar

 LCOE is the industry standard for analyzing delivered energy costs.

 Cost divided by power produced  10 kW.h system on Gabe  $26,000.00 / 275,000 kW.h

 $0.09 per kW.h

Levelized Cost (LCOE) for Solar

 LCOE for this installation is just Nine cents Per kW.h Guaranteed for 25 Years into the future! * 

No other Energy Source can match that; not even close!

10 kW Installation Option A Per watt costs Components DIY Mounts Wiring Inspection Shipping Taxes, fees Misc Labour Total $1.47








Components Wiring Inspection Shipping Taxes,Fees Labour TotaL $1.73







The Numbers….. What To Look For

LCOE of $0.09 per kW.h

Installed cost no more than $2.60 / watt

In fact we just did an install where the LCOE was $0.07 per kW.h and the installed cost was just $2.04 per watt!
