Are You Interested in Solar for Your Home or Business?
Every solar project is unique. System cost is determined by consumption requirements, roof layout, shading analysis, and future energy needs. System costs for residential solar vary from $15,000 to $50,000. The ways to determine system costs are by historic consumption analysis, a home energy audit, or energy modelling for a newly built home. Contact us to learn more.
Solar panels absorb the sun’s energy throughout the day and convert it into direct current (DC) electricity. Most homes and businesses run on alternating current (AC) electricity, so the DC electricity is then passed through an inverter to convert it to usable AC electricity. At that point, you either use the electricity in your house or send it back to the electric grid.
The amount of power your solar energy system can generate is dependent on sunlight. As a result, your solar panels will produce slightly less energy when the weather is cloudy, and of course, not when the sun is down. However, thanks to Ontario’s solar program called Net Metering, your system will send any excess energy it creates back to the electric grid in exchange for a grid credit, which you can redeem in the evenings when the sun out of sight. This whole process saves you money by reducing your energy bills.
Solar panels will still function even with snow on them. However, in Ontario, our climate is such that with fewer daylight hours during the winter season the panels will be covered in snow the system won’t produce enough electricity to power the home.
Studies have shown that homes with solar energy systems sell for more than homes without them. However, your property value will only increase if you own (rather than lease) your solar panel system. In most parts of Canada, a system will actually increase the value of your property more than a kitchen renovation.
If your solar panel system is connected to the grid, it will shut off in the event of a blackout. This is to prevent emergency responders and electricity utility repair personnel from being injured by your panels sending power back to the grid. However, there are certain inverters you can buy that provide backup power in a blackout when paired with a battery.
If you own a home or property that has a pitched roof, your operations and maintenance cost is non-existent. The system will require tweaking in year one, which is covered under the Execon five-year workmanship warranty. As long as your system has critter-guard and there is zero human interaction there will be no need to calculate operations and maintenance into your overall project cost. The manufacturing warranty for the panels is for 25 years, and the inverter warranty is for 10 years. Be prepared to replace your inverter after year 10.
Solar energy systems can last 25 to 35 years, and it can be costly to remove and reinstall them if you need to replace your roof. If your roof needs maintenance in the near term, you should complete it before you finish your solar installation. The Execon Roofing and Solar team is fully equipped to re-roof your home or business before installing solar panels.
After your system is grid-tied and commissioned an Execon technician will help set up your energy monitoring system that will show in real-time what your system is producing 24/7/365. This app for your smart device will not only give you the reassurance that your system is functioning properly it will also allow you to become a solar advocate – by showing it to everyone you know!
