A big tracker is coming to the Kamloops area

Last week Sweet Spot Solar sold equipment for three new rooftop arrays. This week we are thrilled to have sold this incredible two axis tracker to a family in Kamloops. This tracker will be constructed using bifacial modules made by Canadian company Silfab, and it is expected to produce around 22,000 kWh/year of electricity.The bifacial modules capture energy from behind by taking advantage of the albedo effect. It is going on an acreage and we expect it to be a landmark to showcase how solar can make a significant impact on our future sustainability.

With these prices on solar, what are you waiting for?

Here's a quick example of how much a solar array would cost you with our pricing model. You could purchase right now a 16 module array rated at 4.24 kW DC. Depending on your location this could put out between 4800-5100 kWh/year. The equipment portion includes 16 Canadian Solar 265W modules, 16 Enphase M-215 micro inverters, Enphase Engage cabling, rails and mounting equipment for a roof. With delivery and taxes = $9900.00 (depending on location). On Gabriola Island and area our installer can likely do a project like this for approximately $2500.00. From a financial perspective, the levellized cost of energy for this array is 9.92 cents/kWh over 25 years based on 5000 kWh/year, and for 30 years the cost of electricity is 8.26 cents/kWh. No more rate increases! You lock yourself into this price by pre-buying power from your own array on a net metered basis.

Top Of Pole Mounts For Solar

There are so many options for mouting solar. One idea that's taking off is the use of top of pole mounts. Sweet Spot Solar can put together a 10 module package in two rows of five modules (portait orientation) for you. This would include 10 265 Watt Canadian Solar modules with black frames, a top of pole mouting kit (you will have to source the pole from a local metal shop and they usually cost around $400-500), 10 Enphase M-215 micro-inverters, and Enphase Engage cabling. This equipment package costs between $8000-8500 with delivery and taxes depending on where you live. A concrete foundation with rebar or mesh should be poured to anchor it. Here's an example of what this could look like, and the actual 10 module layout. Installation of such a system is likely to be in the $2000 range.



The above illustration is for a 15 module mount. For a 10 module mount there is one less row.

Here comes the sun: Solar farm sites sought in Kamloops region

An article by Cam Fortems in the December 6, 2016, edition of Kamloops This Week discusses the opportunity to develop solar farms in the interior of BC.




Sweet Spot Solar's Michael Mehta stated the following:

"He believes B.C.’s energy solution is in individual units in homes and businesses, rather than with solar farms."

The Grid Zero House: Almost Off-Grid But With A Twist

Some people in British Columbia prefer to keep their existing analogue meter and not make the switch to a smart meter. There are many personal reasons for this decision.

Unfortunately BC Hydro will only allow net metering for clients with a smart meter. You can have the radio-on or radio-off option.

This makes it challenging for people who want to set-up a solar array on their property.

Until now there were limited choices: Go off grid completely or accept the smart meter.

Sweet Spot Solar is pleased to offer you a third option called Grid Zero. This allows you to keep your analogue meter, stay connected to the grid, and have a solar array. This also works with smart meters and adds the bonus of net metering into the mix.

How does this work?

With smart metering (using the net metering program) and a solar array, you remain connected to the grid. Your smart meter records how much power you consume, and how much power you push into the grid and it records excess generation. This creates a rolling credit.

With a Grid Zero system you remain connected to the grid, have battery back up, but you are not pushing extra power back into the grid. There is no credit for excess generation from BC Hydro in this case.

In other words, you are not grid-tie for the solar array but still remain grid connected for your house. This approach works with an analogue meter and does not require BC Hydro approval since you are not feeding their grid. Of course, an electrical permit is still required. The illustration below helps explain how this works.




Sweet Spot Solar can sell you the solar modules and electronics to make this a reality, and for a Grid Zero approach we use an incredible piece of integrated technology called the Wave.

The Wave is a complete plug and play system that includes state-of-the-art battery technology and world-class inverter technology by Outback Power. The system is enclosed in one housing, and it is programmable to work in grid-tie, off-grid, and Grid Zero applications.

The batteries are made using a non-toxic Aqueous Hybrid Ion solution (like salt water) and they come in various sizes from 4000W with 11.85 kWh of storage all the way to a whooping 16,000W at 71.1 kWh. To learn more about the batteries go here. You can watch a video of how this battery is made on Youtube. To learn more about the developer of the product click here.

In a nutshell, Grid Zero works like this:

In the day when the sun is shining, your house is using power from the solar array. If extra power is required, the battery will be used to top up your needs. If still more power is required, that differential will be drawn from the grid.

When the sun is not shining and your solar array isn't producing anything, you will draw from your batteries first and then top up from the grid as required.

The system is designed to keep your batteries charged as well.

This is all done seamlessly by the system, and it cuts down dramatically how much power you need to purchase from BC Hydro. If you size the system right, you may not need to buy anything from them!

The system provides reliability, can be used during power outages, reduces your purchase costs from BC Hydro, and doesn't require a very large array and battery back up system like a full off-grid kit Most off-grid systems also require the use of backup generators frequently during winter months to keep batteries topped up.

For those interested in the technical side of how this inverter technology works go here.

Let us know if this is something we can design and quote for you.

Use the grid as your battery

Net metering is the closest you can get to using the grid as your battery, without having to buy and maintain batteries.
Here's an example from one of our systems for the month of September.
This 18 module system produced a credit for the month of 343 kWh! This amount will be deducted automatically from the October bill for any net consumption.

On Commercial V. Residential Solar Installations

Sweet Spot Solar is delighted to see that a lot of commercial buildings including apartment complexes, warehouses, and large office buildings have expressed an interest in solar in recent months.

As a company whose focus is on providing the best quality product at the lowest price possible, we are uniquely positioned to work in this sector for several reasons.

First, the differences between commercial and residential solar applications have become less pronounced due to changes in technology. Our team members have been involved in some of BC's largest and smallest grid-tie solar photovoltaic arrays, and it's worth noting that some of the largest arrays in the province have been installed on residences.

Second, BC Hydro makes a distinction in terms of interconnection requirements between simple and complex distributed generation. In short, solar arrays less than 27 kW in size on a 200A or smaller service using Single Phase qualifies as simple in terms of the application process for net metering, whereas solar arrays up to 100 kW that don't meet these requirements are automatically defined as complex. We have done both kinds.

Third, the main difference between residential and most commercial arrays is that commercial properties often have flat roofs. We work with engineers through our supplier to design ballasted racking systems to work perfectly on flat roofs. Given the light weight of solar modules (typically less than 45 pounds) plus the balance of the system, these ballasted systems spread the load across rooftops very well. Here's an example of a system that our supplier provides for this application. For larger commercial installations, we use the consulting services of Sentinel Solar in Ontario to do system design.



For example, for a flat roof with dimensions of 73' by 137', our engineers estimated that 160 modules can be mounted on a ballasted rack angled at 15 degrees. Using 265W modules, this array would be rated at 42.4 kW DC. We provided recently a quote for an installed system like this for $140,000 all-in [$3.30/Watt installed is unbeatable].

Solar: Perfect Versus Cloudy Days

Solar modules have become so good in recent years that they can harvest photons from the Sun even on cloudy days. Here's an example from one of our arrays built upon LG 310 modules and M-250 micro-inverters. In the first graph we have a close to perfect solar day with 45.3 kWhs generated. Note the smooth bell curve which indicates no cloud coverage at all.



The second graph, from the same array, is from a day with lots of variability and constantly changing cloud cover. Even on this day the array generated 37.6 kWhs - or 83% of a perfect solar day.




When a system is properly and professionally designed and installed, this kind of performance is normal. Sweet Spot Solar can make your solar dreams a reality.

Best practices for mounting solar on shingle roofs

A natural fear that homeowners have about mounting solar on their roof is the integrity of the installation with respect to water incursion.

In the past, many solar installations were simply screwed down to the roof with lots of a roofing compound placed around entry points. This approach is simply unacceptable on shingle roofs nowadays, and code and industry association requirements demand that flashing be used.

At Sweet Spot Solar we are constantly exploring new product lines and our staff take regularly continuing education programs.

Although our company does not do installations ourselves, we work with installers to provide you with the best project price and the highest quality equipment.

When it comes to flashing for shingle roofs, one of the most effective products we have found is made by Quick Mount PV. Although more expensive than competitors, it's better to spend money on good quality equipment like this upfront rather than risk a leak in the future.

The E-Mount is a specially designed flashing kit that uses an elevated water seal to provide the best possible waterproofing and durability over the long run. We have samples of this product and others like it to show clients when we review your solar needs.



Here's a great video profiling this flashing kit and how it mounts. Hopefully this will give you greater peace of mind when considering a solar option for your roof.

Solar at the cottage/cabin

Here's why a small solar array at your seasonal property makes a lot of sense.

If you have a cabin or cottage that is primarily used in Summer, a solar array will produce a rolling credit throughout the year that will likely neutralize your bills (or create income) on an annual basis.

In the example below, this array of 18 modules is producing significant credit when most of the electrical load is turned off.


When your family is there during the Summer, your electrical demand is met first by what your array produces, any extra consumption is pulled from the grid, and any extra production creates more credit.

For a property that is used primarily in the Winter months like a ski chalet, a solar array makes even more sense since you can accumulate a very large credit during the solar peak months (typically March to October in Western Canada) to reduce or neutralize your Winter bills.

Even a small system of  5-10 modules can make a difference for such property owners.

Another example of net metering

Here's another example of how net metering can work with your solar array. This 2100 square foot house has an array of 18 modules on the roof. Yesterday there were some big demands with two loads of laundry, a bath, shower, dishwasher cycle and a water distiller running for several hours using 1500 Watts of power. The house still produced a credit of 1 kWh for the day, and in the afternoon was pumping almost 3400 Watts into the grid.




A new solar array in Nanaimo

The Sweet Spot Solar team put up another solar system in Nanaimo yesterday. Our team worked on a steep asphalt shingle roof to install a solar ready-plus 1 kW system for $3999 (all-in).

Follow the sun like a sunflower and make 40% more power with a tracker

Sweet Spot Solar has a limited opportunity to provide you with another option for solar involving tracker technology.

This Lorentz 1000 tracker will follow the sun as it moves across the sky each day - and produce 40% more power than a static roof or ground array.

These trackers are mounted on the ground on a concrete foundation. In some cases where proper support exists, this tracker can also mount on flat roofs.

Each tracker will hold six 60 cell modules and could work with our Hanwha 260 or LG 310 modules and their paired micro-inverters.

Solar and the value of your house

A US study led by a researcher from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and a home appraisal expert found that in some markets adding solar to your house generated a 100% return on investment when the house was sold. In other words, for every dollar spent on solar the seller was able to get that dollar back. Try that bathroom and kitchen renovations!

Furthermore, having a house that has low or zero electricity bills is likely to become more attractive to buyers in the future - especially as utility rates increase.



Solar is taking off in BC, and its about time

There has been a rapid increase in net metered solar arrays in British Columbia. We now have around 750 interconnected systems that sell power back to BC Hydro. There is so much room to expand however given that there is 1.7 million BC Hydro clients.




An inverter converts the DC electricity made by the solar module into AC power for use in your home

In most cases, Sweet Spot Solar recommends that your array be built using high-quality micro-inverters like those made my Enphase.
This approach allows for future expansion of the array with minimal cost, reduces power production loses due to shading/shadowing/dirty modules, and minimizes long-term financial risk and system downtime.

It also makes DIY options a breeze! It's all plug-and-play.

It also provides the longest warranty option in the industry (25 years) compared to old-fashioned string inverter or centralized inverter approaches (typically 10 years).
Module by module diagnostics also becomes possible with this approach. An optional Enphase Envoy unit will provide real-time, detailed monitoring of the array with a user-friendly internet-based interface.
All of the technology is on the roof and micro-inverters are mounted under each solar module. This approach also reduces fire and electrocution risks since micro-inverters put out 240V AC instead of high voltage DC as per string/centralized inverters.
Micro-inverters are used to build some of the biggest solar farms in the world, and Enphase has sold millions of them globally. We really recommend this product.
Think of it like the revolution in cell phone technology. At one time cell phones were huge and expensive. A micro-inverter like the Enphase M215 is sweet, small, powerful, and efficient. We sell them starting at $175!
Here are photos of a string inverter and a micro-inverter. We can of course provide you with string inverters from a range of manufacturers too.

Sweet Spot Solar at the Gabriola Island Farmers' Market

Your Central Vancouver Island/Gulf Islands team of Sweet Spot Solar had a wonderful day at the Gabriola Island farmers' market. We met dozens of people and had a chance to hear about the dreams and goals of many people about how they would like to adopt solar. There were many questions about batteries.
Our grid-tie systems connect directly to the utility company's lines through your breaker box, and they don't require batteries. Through net metering you can essentially sell power back to BC Hydro and create a rolling credit. This is all done automatically and seamlessly through your smart meter.
Of course, if you want batteries... we can do that kind of system too.

An Infographic On How To Understand The Financial Returns On Your Solar Plans

Solar is fun and it's definitely the right thing to do on many levels. Lots of people have questions about the financial performance of solar. Here's an infographic that we've produced based on our pricing model and approach for British Columbia clients. We'll work on another infographic for Saskatchewan soon.

Sweet Spot Solar Carries Monocrystalline and Polycrystalline Modules

Sweet Spot Solar can provide you with a range of options for solar modules including high-end monocrystalline modules like the LG 310 (the black one on the right in this photo) to very good quality polycrystalline modules like the Hanwha 265.



We currently sell the LG 310 for $520. It is a 310 Watt module that performs at 18.9% efficiency. It comes with a black frame that is thicker than most competitors, is aesthetically pleasing, and is ideal in situations where you have limited roof space and want to maximize power production. Also, it looks fantastic! It is made in Korea.
The Hanwha 265 is sold for $285. This 265 Watt polycrystalline module is rated at 15.9% efficiency. It is an affordable, high quality module that will work in any application and is made in Poland. This module pairs with the Enphase M215 micro-inverter.
The choice is yours. Although the LG 310 is $235 more per module, and requires a higher output micro-inverter that costs around $30 more, when you consider a system with 10 modules - the overall cost of the best technology only increases system cost by around $3000. There is no difference in cost to install higher output modules. In fact it may be lower due to needing fewer of them to produce equivalent power.
This is part of the Sweet Spot Solar approach. We aim to make high quality solar equipment available to more people, companies and communities while also providing an option to purchase the highest quality equipment currently available (like the LG 310 with an Enphase M250 micro-inverter) for the best price possible.

How Much Sunlight Does Get BC Get?

To understand better how solar works in British Columbia, it's useful to look at some charts and tables of seasonal variation and regional differences.
Below is a sunlight hour chart by month based upon current data for the Central Vancouver Island region. The lighter colour band shows sunrise and sunset times by month.


The following tables also show differences in annual sunshine hours across the province. Worth noting is that places like Kamloops (often perceived as very hot and sunny compared to Nanaimo or Vancouver) has 2080 sunshine hours/year while Nanaimo has 1940 sunshine hours/year. This is less than a 6.7% difference! An extra solar module or two can make up the shortfall quite easily.



Germany - a solar powerhouse in terms of installed capacity - has less sunshine hours in its southern region than Nanaimo (with one exception) and many parts of BC.
