Micro-inverters, like acid washed jeans, seemed like a good idea at the time but in retrospect, not so much. We installed well over 5,000 Enphase micro-inverters that were supposed to have only one failure per year out of every 330 units. In reality the failure rate was as high as 1 in 8 per year …

It is true that the price of panels have dropped drastically and there is still some room to go. The price of panels have come down so much that it is not the most expensive part of a solar system. In recent years the rules have changed and the installation cost have gone up by …

The efficiency of a solar panel is its ability to convert solar energy into power. A panel that has an efficiency of 15% converts 15% of the solar energy that falls on it into power. There is a great deal of hype about how efficient one panel is over another. What efficiency translates into in …

Farm buildings are fantastic for roof-mounted systems. Large dairy or poultry operations may be able to install much larger systems too.
Yes and No. From a technical standpoint, there are few areas in Southern Ontario that are not viable for solar energy. From a practical standpoint it is possible to be denied a connection by your hydro company due to lack of capacity on your local line. If too many people on your line segment install …

Your payments will vary depending on how sunny it is through the month and on seasonal differences. Obviously we get more sun during long clear summer days than we do during short overcast winter days. On average you would generate about 12,500kWh’s per year from a standard 10kW system. This is what the average household …

Every power distribution company is different. The people at Halton Hills Hydro as well as Milton Hydro have been wonderfully supportive and we love working with them. Hydro One has also been very helpful to our efforts. At this time, most hydro companies in Ontario have had enough experience that the process is a smooth …

The short answer is, probably not. The typical grid-tied system is designed to turn off if the grid goes down for safety reasons. That being said there are ways to have power when the grid goes down but honestly a generator would be a cheaper solution.
Unfortunately the rules have changed recently so that we are only allowed to install solar panels on rooftops. You may see a lot of solar installed on the ground or on dual axis trackers but these were installed before the rules changed. Solar panels must be installed on a structure that was not built to …

It depends on the size of installation, the complexity of your roof, and any other factors around your home. However, you can figure approximately 2 to 3 days for the panel install and another day for the electricians.
