Solar Farms


Interested in a hosting a solar farm? I am!!! We are hosting a 15 acre solar farm on our property and hope to start soon. Many predict that every farm will have some sort of energy generation in the future or pay carbon taxes.
Some considerstions for hosting are land parcel size, current land use and possible secondary land uses, zoning, distance to grid of 27.6 or larger, ability to secure a position at the Transfer Station.
One of the major considerations is having a landowner who is enthusiastic and wants to be a partner (by holding the lease) with Arise. There is an opportunity for lease and monthly maintenance payments to the landowner.

Please feel free to ask me more about the benefits by contacting me at asparagus@rogers.com

THREE POLE-MOUNTED 3.2 kW DUAL AXIS TRACKERS


PROPOSED DUAL AXIS SYSTEM
Pole-mounted dual axis trackers require the most amount of space in order to prevent shading adjacent arrays during their tracking path. Each array occupies 3,840 square feet for each 3.2 kW system. Thus, three 3.2 kW pole-mounted dual axis trackers would require 11,520 square feet (0.26 acres) of available land. The trackers need to be spaced apart 40 feet along the North-South axis and require 48 feet to each the East and West to prevent the arrays from shading each other during their tracking path. Each tracker would be connected to an independent 3.3 kW Xantrex inverter.

Each of these 3 are 3.2 kw for a total of 9.6 kw

A sample 3.2 kW pole-mounted dual axis tracker can be seen in this picture. This array is composed of sixteen 200 W panels, arranged in a four-by-four landscape configuration.

GROUND-MOUNTED 9.6 kW SINGLE AXIS TRACKING ARRAY


On average, one can expect to get 1 kW of solar-generated power per 305 square feet of usable area from a single axis tracking array. Thus, a 9.6 kW single axis tracker would require 2,928 square feet (0.07 acres) of available land. This array would be connected to two 5.0 kW Xantrex inverters to convert the direct current (DC) power that is generated into alternating current (AC) power, so that it can be fed back into the grid to receive payment under the Renewable Energy Standard Offer Program (RESOP).

A sample ground-mounted, single axis array can be seen in this picture. A 9.6kW single axis array would be composed of forty-eight 200 W panels, mounted in a similar manner as shown.

Fixed Tracking


On average, one can expect to get 1 kW of solar-generated power per 175 square feet of usable area from a fixed array. Thus, a 9.6 kW fixed array would require 1,680 square feet (0.04 acres) of available land. This array would be connected to two, 5.0 kW Xantrex inverters to convert the direct current (DC) power that is generated into alternating current (AC) power, so that it can be fed back into the grid to receive payment under the Renewable Energy Standard Offer Program (RESOP).

A sample ground-mounted fixed array can be seen in this picture. A 9.6 fixed array would be composed of forty-eight 200 W panels, mounted in a similar manner as shown.

Rooftop


I have a 3.5 kw rooftop system from Arise and I recieve a monthly hydro cheque. I am paid .42 per kwh and the contract is for 20 years with the Province. I rarely need to clear snow as it melts and slides off the glass module. My modules are Sanyo.

For a rooftop system to be effective it needs to be southfacing.

The sun is absorbed by the panels which also adds to the life of your roof.
