A new solar array is coming to Salmon Arm

Congratulations to Tracey and Eric of Salmon Arm BC. They have purchased equipment from us for a small solar array composed of six 300 Watt modules, micro-inverters, and racking to mount this equipment on their shingle roof. This array can be expanded easily at any time, and they can add 10 more modules on the same circuit.

The 1.8 kW array will make approximately 2000 kWh/year.

Once the snow melts, installation will begin. They have opted to do a self-install.

Solar Strata In Kamloops BC

Updated: March 18, 2018

Sweet Spot Solar is thrilled to be working with Miles Pruden of Nexbuild Construction Corporation in Kamloops on the first solar multi-unit residential building in the city. Nexbuild purchased from us 64 300 Watt monocrystalline solar modules coupled with industry-leading Enphase micro-inverters and rail kits for their metal roof (19.2 kW) for $2/Watt! They will install the array. Each array is independent and has its own monitoring. This complex will have four separate solar arrays of 16 modules each, and the goal is to be net zero on each unit. No gas is used for heating or hot water purposes.Here's a rendering of the complex being built right now at 225 Schubert Drive in Kamloops.

As of today, only one unit remains available for purchase and it is located on the top floor. Asking price is $349,000. For more information, contact Miles at milesp@nexbuild.com

Here's what the building looks like currently. Occupancy of the first unit is expected in a few weeks.

Miles and his team began installation of the solar arrays this weekend. Here are some photos provided by him of their progress. With a standing seam metal roof, and the use of S5 clamps, these projects are relatively easy, quick, and put no holes in the roof.

Another Example Of How Net Metering Allows You To Use The Grid As A Battery

A 4.5 kW solar array on Gabriola Island has been creating enough power for a 2400 square foot house to generate a surplus that is going into the month of December.

Here's a daily log of energy consumption for the house for the month of November. Going in to November this BC Hydro client had banked 1217 kWh of electricity. This is the rolling difference between what the solar array produces and what the house uses.

During the month of November the house imported 514 kWh from the grid leading to a new balance going into the December billing cycle of 702 kWh. You'll see from the bill below that the energy charge is $0.

To date, this house has used $224.22 (since February 1, 2017) with $61.00 of that being in the form of the basic daily charge, rate rider, and GST.

It's worth noting that the house uses electricity for 100% of its heating/cooling (there is no natural gas), runs two UV sterilizers for water purification (100% rain capture), operates 3 air purifiers 24 hours per day due to wood smoke from neighbouring properties, and charges an electric car.

Sweet Spot Solar Is Experimenting With Vertical Axis Wind Generators

Wind and solar might just be a match made in heaven. Sweet Spot Solar is experimenting with this technology and will adapt it with a CSA approved grid tie inverter. If it works as hoped, we'll have a new product line to go with our solar offerings. Stay tuned to our website for updates.

Canada's first solar sidewalk system is in Kamloops

Innovation in solar technology is expanding at a record pace and new applications for solar photovoltaic technologies push boundaries and open up new opportunities.

Canada's first solar sidewalk system was built this year on campus at Thompson Rivers University in Kamloops BC.

The following article from the BC Sustainable Energy Association provides details about how all of this came together.

Your Return On Investment (ROI) For Solar Can Be Up To 5.8%

With our current sale on equipment, a roof-mounted solar array composed of 16 modules (4.24 kW DC) will cost you $7999 (all-in). If the installation comes to $4000, your full installed cost is $11,999.

This can return 5.8% for you and in 25 years it would generate $45,000 worth of electricity.

Here's how this works. This array will produce around 5000 kWh/year using Kamloops as a baseline on a house with a 20 degree pitched roof facing due South.

The average house in BC consumes 11,000 kWh/year. Since BC Hydro charges a 50% premium on electricity (so-called Step 2 pricing), most of the 5000 kWh/year produced by the solar array will go toward reducing Step 2. Currently, Step 2 electricity with the 5% rate rider and GST works out to 14.19 cents/kWh.

Over the past 7 years, BC Hydro rates have increased by 50%. We don't have a crysal ball to know what rates will look like in the future, but they won't go down! Using this as an annual average rate increase, we get the following table.

This table shows in the right-hand column the annual expected saving in a cumulative way. By year 12 the array has paid for itself. Most solar arrays will last 30+ years. We did include a degradation calculation (see decreased output per year) in this model since solar modules will lose on average about 0.1% of output over time.

The following graph shows the break even point.

Of course, financials are only part of the picture. A lot of our clients also want to "do the right thing" and to show how individuals can make a difference.

A year in the life of a solar array on Gabriola Island

On August 23, 2016, a new solar array was commissioned on Gabriola Island. This array is composed of 28 LG310 Watt modules and Enphase M-250 micro-inverters. It was installed on this stunning garage.

Sweet Spot Solar estimated annual production for this 8.68 kW DC array at 9765 kWh/year under ideal conditions on an annualized basis.

For the year, the array generated 9290 kWh. For this year, the longer than normal winter combined with several weeks of smoke from forest fires reduced output by 4.87% from our original estimate.

Note the deep drop in production between the months of November and February. This is typical of a solar array at this latitude. During the Spring, Summer, and early Fall a solar array makes lots of extra power that gets banked as a credit with net metering through your smart meter to offset your winter bills. All without batteries!

From an environmental performance perspective, our monitoring software yielded the following calculations.

Our big tracker is in the news!

An article in InfoNews-Kamloops today profiles the tracker owned by our clients Penny and Charles.

Even with the incredible amount of smoke in the area for more than a month, this tracker is making enough power daily to power 2-3 average homes.

The article states:
After installing the largest sun tracking solar panel in B.C. on their farm in Black Pines just north of Kamloops, Charles Hays and Penny Powers expect to never pay for power again.
If all goes according to plan, the power company will pay them.
Charles Hays and Penny Powers hope their story will inspire others.

Dual axis tracker in Black Pines BC

A big thank you to electrician Amie Schellenberg from Lodgepole Electrical and general contractor Jono Beech for getting this big and bold tracker installed and running.

This 45 module tracker follows the Sun like a sunflower and it will produce more than 25,000 kWh/year.

By 11:15AM today it had already made more than 30 kWh of electricity - enough to power the average home in BC for a day.

It is located on the outskirts of Kamloops in Black Pines and you can see how beautfully it fits into the local environment.

To see how this came together, check out our featured post here.

Even on extremely smoky days our solar arrays make power

Even with several very smoky days in the interior of BC from forest fires, our new tracker on the outskirts of Kamloops managed to make a whopping 1000 kWhs or (1MWh) in just 13 days! It's best day resulted in 90.9 kWh - enough to power three average houses.

Another illustration of how net metering works

Here's another example from one of our solar arrays of how net metering works. On June 28, 2017, this array composed of 23 modules on a 2200 square foot house produced a credit of 15 kWh. In other words, it sent 15 kWh of electricity into the grid and the smart meter recorded that surplus generation.

There are some features of this graph worth noting. First, between Midnight and 7AM the house pulled electricity (consumed) from the grid. By 8AM the house's solar array began producing more electricity than the house used and it continued to do so until 6PM. Second, the magnitude of the bars going down (credit) peaked at solar Noon, and the distribution of energy production follows a normal curve shape on a sunny and clear day - assuming that electricity consumption in the house is constant.

This array has already generated a surplus of 136 kWh for the month of June that will roll into July. A surplus in July will roll to August, and so on. With net metering, and a large enough solar array relative to consumption, you can create a substantial credit to reduce your winter billing. This is why solar works well and also why batteries are not required.

Solar Is An Excellent Investment

If you're a resident of British Columbia, you've probably noticed that your BC Hydro bills have increased in recent years. Since 2010, residential rates for electricity have increased a whopping 50% for an average annual increase of 7.14%.

With your own solar array, you can take back the power and control future rate increases.

Here's a typical example of a solar array that Sweet Spot Solar can do for you:

* 28 solar modules rated at 305 Watts each will build an 8.54 kW DC array that should produce on average 10,191 kWh/year under ideal conditions on an annualized, multi-year basis assuming a roof pitch of at least 23 degrees [in the interior of BC].

* Sweet Spot Solar's average price for the equipment is around the $20,000 mark (all-in with delivery), and one of our recommended installers can often commission such an array for $6000.

Assuming an installation cost of $6000.00, your array from us will cost $3.03/Watt. This is more than 30% below the British Columbia average.

* Your array is an excellent investment that will generate a return on investment of 5.6%/year. The payback time for the array is 12 years, and over 25 years it will save a total of $91,992.00 on energy bills for a profit of $66,092.00 (savings-installed cost).

Take that BC Hydro

Solar saves you money! This 2200 square foot house in BC has a solar array composed of 18 modules. During the month of May it used only 39 kWh from the grid, and its total bill from February to June is $186. The owners will likely not purchase electricity until October or November but by then a rolling credit of surplus production can be drawn upon. This is the beauty of net metering.
This house does not have access to natural gas and heats with electric mini-split heat pumps and uses electricity for hot water. It also charges an electric car!

Clouds and solar power production

How well do solar arrays work on cloudy days? Today in Kamloops we had a cloudy day with lots of storm activity circling the city. In spite of this, all of our monitored solar arrays managed to produce between 60-70% of optimal output.

A new array in Kamloops

Congratulations to Adrian and Sara for their new array. This array is located in the Lower Sahali neighbourhood of Kamloops.

Adrian provided the following endorsement:
Since moving to Kamloops, a city that boasts a lot of sun, I have been interested in installing solar panels. In February I flew over a massive solar farm in the deserts of Western China and was really impressed by the potential. But it was a recent trip to England (yes, rainy England!) that showed me that progressive people are installing solar panels all over the world on their homes. Working with Sweet Spot Solar was a wonderful experience, right from the home visit for an initial assessment, to the installation, and finally to the moment I saw on my mobile phone app that I was generating my own power. 

It is composed of 15 monocrystalline Silfab 285 Watt modules coupled with Enphase M-250 micro-inverters. This is a very high quality system that will produce approximately 5100 kWh/year.

The array is mounted on rails on their shingle roof and it is split into two sections.

Our installer worked around existing vent stacks to maximize roof coverage and it looks like several more modules can be added in the future.

On it's first full day of operation (May 22, 2017), this array made an impressive 28.9 kWh.
