If you’re wondering which of these two options are better for you, then you’re at the right blog!

Let’s face it, we would all like to be off the grid generating our own electricity and telling our local hydro company not to bother sending us another bill – ever! It’s also nice to take comfort that during a thunder-storm when the lights go out, you’ll be watching T.V with your lights on while your neighbours sit in the dark. It’s a pleasant thought however not always practical, economical or to your benefit.

First of all, just in case some readers are not sure about what Grid Tied or Off Grid Solar electric systems are, here’s the difference

Grid Tied Solar Electric System: In this case, your solar system generates power through your solar panels and you sell ALL of that power to your hydro company at a preferred rate (often guaranteed for 20 years). You will then buy electricity (including your clean solar electricity that you produce) as you normally would however you will buy this power at the standard lower rates for electricity that we all pay.

To take part in this Provincial Solar incentive program, (called the MicroFIT program in Ontario), you would be required to apply to the Ontario Power Authority for approval. To be eligible, you are required to own your home and your system cannot exceed 10 kW’s in total. Your Solar installation company can help you navigate through the approval process. ( In case you want to know if your home is fit for solar you can find out the requirements here)

If you look at your hydro bill, you’ll see that here in Ontario, we all buy our electricity at a rate of 6.7-12.4 cents per kWh (depending on the time of day). Under the MicroFIT program, generating electricity with solar power and selling it to the grid will pay you a premium rate per kWh (current June 2013 MicroFIT rates are at 54.9 cents per kWh) and that rate is guaranteed for 20 years! Since the average Solar system costs between $25-$40,000 before taxes, you can expect your investment to pay for itself in about 8-10 years. As your OPA contract runs for 20 years, the remaining 10-12 years will be money in your pocket.

Off Grid Solar Electric System: For Off Grid systems, you are completely off the grid as your system generates power through your solar panels and that power is used for your own consumption. In this case, you will require batteries to store that power to be used in the evening or on cloudy and low producing days.

The trouble with Off Grid Solar systems is that you need to truly understand your electricity consumption and then you need to build the size of your array to the worst month of the year (let’s say January) so that it will still meet your minimum daily requirements. With Off Grid systems, you now need to purchase and hold a bank of batteries (amount and size of batteries to be determined by the size of the system) to store the electricity you generate. Batteries are not cheap and they typically only last about 10 years before they need to be replaced. Chances are, you will need a back-up generator for the times when your system is not be able to meet your requirements in the worst producing months of the year. These batteries can add at least a third of the cost of what a Grid Tie Solar system would be. Lastly, an off grid system is a lifestyle change as you need to conserve electricity wherever possible.

At the end of the day both systems have their merit. Off Grid systems work best in areas of the Province where you cannot connect to the grid in any other way, typically in rural settings. Grid Tie systems are better in an Urban environment where Hydro is readily available.

How much money can I make under the microFIT program in Ontario?

6 Jun

Eco Alternative Energy is back to answer your questions about Solar.  A lot of our customers at the earlier stages of reaching a decision wonder if its true that they can make money under Ontario’s microFIT program. And once we tell them IT IS TRUE, the next question they have is , well ” How much? ” The answer, though it depends on a couple of variables, is pretty simple – your payments will depend on the size of your system, the pitch of your roof and any shade considerations.

Earn with microFIT, Ontario Solar

Under Ontario’s microFIT program, you get a cheque from your Hydro company every month

It might sound a lot here, but it’s not. The size of you system means – what kind of solar panels you decide to go with and how many. This can be easily figured out via satellite imagery and we have specialized tools to calculate shading. So it only takes us a few moments to come up with a close approximate for your proposal once we have all the information. Once you install a solar system, under the microFIT you will get a cheque from your Hydro company every month. Isn’t that great? We think so too!

If you are a homeowner or an eligible participant, you have the opportunity to develop a very small or “micro” renewable electricity generation project (10 kilowatts or less in size) on your property. Under the microFIT Program, you will be paid a guaranteed price for all the electricity your project produces for at least 20 years and in the current phase the rate being offered is 54.9 cents per kWh guaranteed for 20 years.

Going back to the ” how much money question” – your cheques will typically be larger in the summer months (longer days, more sunlight) and less in the winter months. The average household can expect to earn approximately 10% return on their investment each year of their 20 year contract with the OPA. We will provide you with a realistic estimate based on actual conditions for your home or business.

If you’ve read our post about how to find out if your house is a good fit for solar you already have an idea on how a house is evaluated but you can always Contact Us if you still have questions about solar.

How do I know if my home is right for Solar ?

Solar Panel Installation by Eco Alternative Energy

Solar Panel Installation by Eco Alternative Energy

We’ve been doing solar installations for homes for a long time in Ontario. One of the most common questions we are asked by our customers is ,” How do I know if my house is a good candidate for solar? Or  How do I know solar can be installed on my roof?

Well it’s easy. All you need is a quick look at your house by a solar professional – via satellite or in person. Before installing Solar on anyone’s home, we at Eco Alternative Energy first conduct an inspection of the property either through satellite imagery (first) or in person.
We basically look for :

  1. A good Southern, Western or Eastern exposure (although south is best, east and West roofs can still be very rewarding).
  2. The pitch of the roof (25-50 degrees is typically optimal).
  3. Any shade considerations to avoid? (trees, chimneys, plumbing stacks)

Our Solar inspectors have specialized tools to perform a shading analysis to determine if shading will be a problem for your site. Cutting back trees may be a solution and we will advise accordingly.
After determining the size of the best system for you, we can then determine your systems estimated production in kilowatt hour ’s (kWh’s) based on your roof pitch, azimuth, and shading and provide you with an fairly accurate projected return on investment. Once you have a sense of how much energy your system will generate, you can evaluate the cost of purchasing.
Installing systems smaller than 2kW may not be worth your while. If you’re trying to do the math yourself, then figure each panel as is about 5.5 feet tall by 3.3 feet wide.
