Seven years of solar panels

Seven years ago, Matt and I decided to put solar panels on the barn. We felt like it would be a good investment (mostly Matt) and a way to do our part for the environment (mostly me). I feel like we’re fulfilling both of these goals.

Every spring (or summer when I forget), I run the numbers for our panels. Here is this year’s solar report.

If you need to get caught up, here are all of the previous updates and other details:

This year the panels generated the second largest amount of power ever. We made $5,036.38. (We’re hooked into the grid, and the province pays us $0.396 per kWh). We haven’t been over $5,000 since 2016-17. I wonder if this is perhaps an ominous sign that there are more sunny days due to global warming. I am happy that we have the solar panels to counteract our carbon footprint just a little.

Every year, we come out ahead in terms of what we spent on electricity versus what we made. This year, the total was $2,485.63 spent. With $5,036.38 earned, we had a $2,550.75 profit.

I always like to see how close we are to finally earning as much as we spent to install the panels ($40,727.46). This year, we’re three-quarters of the way there. $32,164.07 or 79% over the last seven years. I had originally estimated it would take 8.5 years to pay off the panels, and we seem to be on track for that.

Living at the farm, we’re close to nature and I feel strongly our environmental impact. I am grateful for the money the solar panels generate, and I’m grateful that we were able to make this choice for the planet.

Does anyone else track their utility bills and compare each year? How are you “going green” at your house?

Solar panels turn six

Six years ago, at the end of April 2014 (wow, that feels so long ago), we turned on our solar panels and started generating power. Every spring since then, I’ve written a post sharing how our little power station is doing (you can see the panels on the right side of the lower barn roof in the photo above). This year, our solar-versary beamed right by without me noticing. (Can’t imagine what else would have been on my mind.)

So today I’m getting caught up.

If you need to get caught up, here are all of the previous updates and other details:

Solar panels on the barn roof

Over the last year we spent $2,683.97 on electricity (this is our lights, pump, heat, fridge, stove, etc.). And we made $4,349.94 from the solar panels (we’re hooked into the grid, and the province pays us $0.396 per kWh). Yay to coming out ahead.

Annual income from solar panels

Last year we finally crossed the halfway point in making our investment back–over the previous 5 years we had made 56% of what we invested in installing the panels ($40,727.46). Now we’re passed the two-thirds mark–$27,127.69 or 67%.

Monthly income from solar panels

More than ever, I am grateful that we invested in these solar panels. Our finances have obviously changed since Matt’s death. Having the money from the solar panels and knowing it will cover our hydro costs is a comfort.

And even though I focus on the financials in this update, I strongly feel solar panels are the right choice for the environment, and I’m glad that we were able to take this step.

Solar panels five years later

It’s been five years since we turned on our solar panels. Each spring, I look at our numbers to compare how we’ve done each year and see how much money we’ve made overall.

Here are previous year’s updates:

If you want to get caught up on how this all started, my Going Solar series covered all of the details of our install and our array:

And now to the latest update.

If you’ve been following along, you know that the power we generate goes back to the provincial grid, rather than to our own use. We paid to install the panels, but the province pays us for the power they produce.

Last year we made $4,595.18, bringing our total income over the past 5 years to $22,777.75.

Annual solar income over 5 years

As of this year we’ve made 56% of what we invested in installing the panels ($40,727.46). Solar panels are obviously a long term investment for us (our contract with the provincial government pays us $0.396 per kWh and runs for 20 years).

This year’s profit was the third highest since we powered up the solar panels. As always, the weather determines how much power we generate, and it varies every month and every year.

Monthly solar income over 5 years

But like always, what we made far exceeded what we spent on power.

We paid $2,595.02 for electricity last year, meaning we came out $2,000.16 ahead.

Solar programs vary a lot depending on where you live and what your goals are. As well, solar technology has come a long way since we installed our panels 5 years ago. For us, our system has been working really well for us–both environmentally and financially–and we’re really happy we made this decision.

Solar panels four years later

Solar panel array

Four years ago on April 25, 2014, we powered up our solar panels and began feeding electricity back to the provincial grid.

Every spring, I like to look at our numbers and compare how we’ve done with past years. Here are our previous annual summaries:

We don’t track how many kilowatts we generate, so all of my calculations are financial.

Over four years, we’ve made a total of $17,469.28.

Our initial investment in the panels was $40,727.16, so I guess you could say we still have awhile before we’re truly ahead (based on this year’s numbers, our total payback period will be just under 8 1/2 years).

However, we already feel like we’re ahead every year because we consistently generate more power than we consume.

Last year, we paid $2,594.40 for electricity, and we earned $4,855.15–$2,260.75 in “profit.”

The amount of power we produce is very much determined by the weather, so we see a lot of fluctuation month-by-month and year-by-year. Last year we made more than $300 more than the year before. Here is the comparison over the last four years.

Solar panel income over the last four years

Obviously solar panels are a big investment. Knowing that we’re going to be at the farm for a long time, it’s a choice that made financial sense for us.

And now that we have Ellie, I feel even more strongly about the environmental reasons that we chose to install our solar panels. I want to do my part of create a healthy world for her and set an example of taking personal responsibility for the planet.

For all of the details on our solar panels, you can see previous posts about Going Solar here.

What does it mean to be “off the grid”?

A bit more than a week ago, Matt and I watched the final episode of Sarah Richardson’s latest show, Sarah Off The Grid. For those that don’t know, Sarah Richardson is a popular Canadian TV personality and designer.

She does beautiful work, and I was excited to see a new show from her. I was particularly excited because this series was all about her and her family building an “off-grid” house. The shows were mostly focused on decorating–that’s what Sarah’s known for mostly and I of course enjoyed seeing the beautiful spaces she created.

I was a bit disappointed that they didn’t share a lot of details on the off grid portion. In fact, I couldn’t find any photos of the barn with its solar array to include in this post (all photos are from HGTV).

What they did feature made me think about what it means to be off the grid.

For Sarah and her family, they were focused on being off the hydro grid. A large array of solar panels provides all of the power needed. Woodstoves and fireplaces supplement a heating system that runs on propane. They installed a well and septic system (drilling the well took a few tries as they had trouble finding enough water, and there was discussion of adding a cistern, but I’m not clear if they had to do that as well).

For me, when I think of off the grid, I tend to go all the way to self-sufficiency. In particular, avoiding fossil fuels. So I was a bit disappointed to see Sarah’s crew installing a giant propane tank.

I love at our farm that we generate power through our solar panels, we have no need for propane or oil thanks to our geothermal system, and our well and septic handle all of our water needs. We could be self-sufficient.

We’re not self-sufficient because our solar panels are not off grid. They feed back into the grid, and we’re paid for the power we generate. We then draw the power we need for the house from the grid. Usage and production are completely separate. Batteries, and potentially more panels, would be needed if we wanted to disconnect from the provincial hydro system entirely (like Sarah was able to do).

I’m not sure why Sarah elected not to do geothermal. Perhaps the (small) amount of power required to run the system was too much for their solar panels, which also had to run the rest of the house. Perhaps it was a budget consideration. Perhaps the system required for her (giant) 5,000 square foot house would have been too difficult to set up.

They did take a number of steps to ensure their house is as energy efficient as possible from insulation to lighting to windows. Sarah’s husband Alex shares some of his tips in this video.

I was glad to see environmental impact considered throughout the build and the show. That’s a message I don’t often hear on other shows. I wish they had focused on it even more and explained more of their thought process about what off the grid means to them.

Tim at Design Maze posted recaps of each episode, including more beautiful photos.

What does off the grid mean to you? How are you minimizing your home’s impact on the environment? Did you watch Sarah Off The Grid? What did you think of the show?

Solar panels three years later

Solar panels

Forty solar panels. Three years. $0.396 per kWh.

Grand total so far? $12,614.13.

It’s been three years since we turned on our solar panels. As I’ve done for the last two years, I’m looking back at how much income we have generated. Here’s the summary from our first year and from last year.

As a reminder, we’re part of Ontario’s microFIT program. Under this program, we installed solar panels, and then the power that we generate goes back into the provincial grid. We have a 20-year contract where the province pays us $0.396/kWh. You can read about the whole saga of Going Solar here.

The grand total that we made on our solar panels last year was $4,519.09–close to the previous year’s $4,473.91 but up just a little.

Here’s the comparison over the last three years.

Solar panel income over the last three years

After a dismal January–seriously, in the whole month we had less than 50 hours of sunlight–things started to brighten up. We even had a few days of double digit income in February, which is a very good day in the winter.

Solar panel array

Beyond looking at the income we generate on its own, the other check I like to do every year is comparing the income we’ve generated to what we’ve spent on hydro. This year, we came out ahead by $828.06.

It is such a nice feeling to know that our electrical bills are essentially covered.

The solar panels were a big investment three years ago. We’re still looking at about 6 more years before we’ve generated as much revenue as we put out for the panels and the install. However, we’re a third of the way in both time and money, so we’re right on track.

Also, our motivation in going solar is not solely financial. As nice as the money is, it’s equally as nice to feel like we’re making smart choices for the environment, for the future and for our little corner of the world.

Solar panels two years later

Two years ago we flipped the switch on our solar panels. It’s hard to believe we’ve had them that long. They’re still a bit of a novelty for us, and we check often to see how much power we’re generating.

Solar panel array

Last year, I took a look back at our first year, remembering some of the highs and lows, and calculating how much we’d made and how long it would be until we’d made as much money as we invested in the panels.

I’ve been waiting to do the same thing again and see what progress we’ve made.

Last year, my calculations were only based on part of the year. While the panels were live as of the end of April, we didn’t receive our first cheque from the hydro company until July. This year is the first time we have a full 12 months of payments.

Just in case you’re new to our solar saga or don’t remember all the details, we’re part of Ontario’s microFIT program. Under this program, we install solar panels, and then the power that we generate goes back into the provincial grid. The province pays us $0.396/kWh. You can read about the whole saga of Going Solar here.

But now onto this year’s report.

The grand total that we made on the solar panels last year was $4,473.91–up just a bit more than $850 over the year before.

So what does this look like? Something like this. The golden yellow is this year and bright yellow is last year.

Bar graph of income from solar panels

We had a better fall and winter this year compared to last year. Everybody knows it was a much milder winter, but it was also sunnier.

I was often amazed when Matt told me at the end of the day how much we’d made. When the sun’s in the southern hemisphere, it sometimes doesn’t matter how bright it gets during the day. The angle of the sun is just so bad that there’s no way our panels produce at their max. But even in the depths of winter we had days where we were making double digits, which was a huge win.

The other huge win this year was finally getting our HST refund. This is the 13% sales tax we pay in Ontario on pretty much everything–including the labour and materials to install our panels. Because we run the solar almost like our own small business, we’re able to claim a portion of the tax–in the amount of more than $4,000.

Our other big numbers were finally setting a new daily record when we finally broke the $28 mark and making $831 more than we spent on electricity for the whole year.

Because it was such a mild winter, we didn’t have any issues with snow on the panels like we did last year. Even the ice storm wasn’t a big deal.

In fact, now that we have them, we really don’t have to do anything–except count the deposits to our bank account.

Solar panels

Last year, I estimated that it would take about 9 years and 4 months before our income equaled the investment we made in the panels. When the panels were first installed, I thought 8 1/2 years was a realistic estimate. Using this year’s numbers, the payback period would be just over 9 years.

This is definitely a long term investment, but the money is only part of the equation for me. I really feel alternative energies like solar are something we need more in the world. And I feel like I have a personal responsibility to support these alternatives as I can.

At the farm, we rely on our own well for water and our septic for sewage, we have geothermal for heat and air conditioning, and we generate power for the grid through these solar panels. Plus we’re preserving 129 acres, doing our best to be responsible stewards of our own little chunk of the earth.

Solar one year later

A year ago, we flipped the switch on our solar panels and started generating electricity. I thought it might be neat to take a look back at the past year and see how our little generating station worked out.

If you want to catch up, here are all of the previous posts about Going Solar.

Just a reminder, we’re part of Ontario’s microFIT program. Under this program, we install solar panels, and then the power that we generate goes back into the provincial grid. The province pays us $0.396/kWh.

Over the past year (10 months actually, since our first payment didn’t arrive until July), we made $3,621.13. Each month the hydro company pays us for the electricity we generated two months before.

Graph showing income from solar panelsJust for comparison, we spent $2,604.35 on electricity for the same time period (including the wee bit of power it takes to run the panels). That’s a profit of just over $1,000. Yay to coming out ahead!

Our inverters tell us roughly how much we make each day. So far, our record is just over $29. Matt so badly wants to break $30.

When the panels were first installed, I estimated it would take 8 1/2 years before our income equaled the investment we made in the panels. Using the numbers from the past 10 months, it looks like the payback period is about 9 years and 4 months. I’m optimistic that spring is going to be a good generating time for us, though, so I think the 8 1/2 is still achievable.

The winter was pretty dismal. There were lots of days where the income was in the single digits. The sun being in the wrong hemisphere was the biggest problem, but then there was the snow. Snow on the panels drove Matt crazy. After a couple of big storms, he climbed up on the barn roof with a broom and very gently cleared the panels.

Clearing snow off solar panels

The solar array is pretty big though, and Matt’s arms are only so long. There was one hard-packed drift that he just couldn’t reach. This thing was his nemesis.

Snow on solar panels

Eventually, with some yoga-like contortions and gentle shovel work from Matt, combined with the help of–what else?–the sun, the drift slid down the panels and off the roof in big icy sheets.

Ice sheets sliding off solar panels

Once we hit February, we started having lots of sunny days. As the sun returns to the northern hemisphere, our output has been climbing every day. Even cloudy days result in double digits.

Beyond the snow, we’ve had no issues at all. The inverters and the panels all are chugging along, the money is trickling in, and we’re doing our part to generate some clean power. We’re really happy with our decision to install the solar panels.

Going solar – Show me the money

It’s time for the final post in our solar panel saga. As we all know, going green costs green. Today, I’m going into the numbers (in a slightly artistic fashion).

Read on to find out how much our solar panels cost, how many kilowatts they produce and all of the other details for our solar system.

Solar panels cost and output

Obviously, our solar array and its associated dollars and cents are specific to the Ontario microFIT program. I expect some of our numbers will translate, though, for others who are setting up their own systems.

The last outstanding part of our solar project is to receive our first payment from the hydro company. I have to say I’m looking forward to moving on to the payback stage of this project.

Going solar – I’ve got the power

This week, I’m sharing all of the details on our solar panel project. For the first post, click here.

When we last left off, we finally had an approved application, and we’d made it through a wicked winter. But we were running out of time to complete our panels by the end of our contract.

Preparation

The first step to get ready for the install was an engineering assessment. We had to make sure that the barn was strong enough to hold the weight of the solar panels. Even though the barn is (at best guess) more than a hundred years old, it’s rock solid, so there was no concern there.

The second step was the building permit. Again, there were a couple wrinkles in the application paperwork, but our contractor was able to straighten them out

Installation

The actual solar install finally started at the end of March. First step was the inverters. These “convert the DC (Direct Current) power from your panels to AC (Alternating Current) before feeding it back into the hydro grid.” Our contractor’s web site calls the inverters “the brains” of the system.

Solar panel inverters

Then came the panels. Solar panels work best if they face south. The sun is strongest and hits them most directly from this direction. Fortunately, the back roof of the barn faces exactly south. Given the long delay in our application process, we had lots of time to observe the barn, calculate sun and shadow patterns and determine the optimum position for our panels. We have a long row of very tall pines along the west side of the barn. They’re so tall that in the late afternoon they cast a shadow on the upper barn roof, so we decided to install the panels on the lower lean-to roof as far away from the pines as possible.

Solar panel install on the barn roof

Three rows of racks went up on the lean-to, and then came the panels. We have a total of 40 panels, the maximum we’re allowed under the microFIT program. Panel install took about three days.

Connection

After the last panel was installed, it took another two weeks before the snow had melted enough for the trench to be dug between the barn and the hydro pole. Remember we’re feeding all of the power we generate back into the grid, so connecting into the hydro pole was essential.

Of course, it wasn’t simply a matter of waiting for the snow and frost to melt so that the trench could be dug. The trench was more than 300 feet long. Over that distance, we needed a special heavy-duty type of wire, so that we didn’t lose power. Pulling the wire through the trench was another bit of fun. When the trench was dug, the excavator laid a conduit in the bottom. It looks a bit like weeping tile.

Trenching for solar panels

There’s a rope running through the pipe. The trench is back-filled and the conduit is completely buried. To get the wire from the panels to the pole, our contractor had to pull it using the rope in the conduit–a heavy, 3-person job.

April 23 was connection day. Inspections had to happen. Power had to be shut off. Wires had to be hooked up. And everything had to be turned back on again. There were two or three different groups involved, along with our contractor. This was another instance where I was very glad for professional help. I would not have wanted to coordinate everyone.

But it turned out all of the scheduling didn’t matter.

Meter connection for solar panels

Connection was a no-go. The hydro inspector wanted to see the wire and conduit laying in the trench, but the trench was back-filled. The excavator had installed a T with a small section of conduit that looked down to the bottom of the trench and the wire, but that wasn’t enough. A section of the trench had to be dug out down to the wire so that the inspector could see it. Fortunately, the trench was re-excavated April 23, and by April 24 we were connected.

April 25, our contractor came out and walked us through all of the equipment and how it worked. He flipped the breakers and we were live.

In the infamous words of Snap, I’ve got the power!
