What if I need a new roof or am building a new house?

This is the ideal situation for installing solar. The solar design can become part of the plans to ensure the best use of that space once the roofing has been installed.

Are there any hidden costs involved? (Home Insurance)

There are zero hidden costs. SunFlow Solar prides itself on a A to Z, turnkey operation. All our govern- ment applications, permits, renderings, engineering, installations, and warranties are what they seem. But we encourage you to insure your panels with your home Trenching and Squirrel Guards are not included in price.

How much weight will solar panels put on my roof?

Our solar systems typically weigh no more than 3.2 lbs/sq ft, far, far below what any normal roof can handle.  Rest assured that a structural engineer has to sign off on the design before your house can have solar panels installed.

If I rent a home or apartment, can I still get a system?

No. Solar electric systems are available only to property owners.  However, in some long term lease arrangements, like some commercial leases, for example, it may be possible to make arrangements with the owner to install solar.

What is net metering?

Net metering measures the difference between the electricity you buy from your utility and the electricity you produce with your solar energy system. Under net metering, any excess electricity produced by your solar energy system is delivered back into the utility grid, effectively spinning your meter backwards. Your meter spins forward when your solar energy system is not producing all of the electricity you are currently using. Your electric meter keeps track of this net difference as you generate electricity and take electricity from the utility grid.

Is net metering available where I live and work?

Net metering is a policy that allows homeowners to receive the full retail value for the electricity that their solar energy system produces. The term net metering refers to the method of accounting for the photovoltaic (PV) system’s electricity production. Net metering allows homeowners with PV systems to use any excess electricity they produce to offset their electric bill. As the homeowner’s PV system produces electricity, the kilowatts are first used for any electric appliances in the home. If the PV system produces more electricity than the homeowner needs, the extra kilowatts are fed into the utility grid.

Can I convert from microFIT to Net Metering in the future?

Yes, SunFlow Solar System specializes in all aspects of solar including MicroFIT, Net Metering, Off Grid for Residential and Commercial Applications.

What do the terms on-grid and off-grid mean?

On-grid, grid-connected or grid-tied means connected to the utility electrical grid. Our solar electric systems are designed as on-grid systems, meaning that they interconnect with your existing utility service. Off-grid refers to systems that are not connected to the utility electrical grid.

What are the components of a solar system?

A solar electric system, also called a photovoltaic (PV) system is made up of different components. These include PV modules (groups of PV cells), which are commonly called PV panels, , an inverter for a utility-grid-connected system and when alternating current (ac) rather than direct current (dc) is required, wiring and mounting hardware or a framework.  These are the components for a microFIT solar system – the kind the government is giving contracts for.  An off-grid system would also have one or more batteries and a charge regulator or controller.

Can I be totally independent from the utility?

Our solar electric systems are designed to interconnect with existing utility service. Off-grid systems must be custom designed. We can assist you with this.

What are the costs for maintenance?

No regular maintenance is typically necessary for your solar system.  With no moving parts and long term warranties, you can relax knowing you’ve invested in a very stable, reliable money maker.

Will my system work at night?

No. Sunlight must be present for your solar modules to produce power. At night, you draw power from your utility.

Why is shade a problem?

Because of the wiring design of a solar module, all of the individual solar cells on a module must receive full sunlight for the module to work properly. If any portion of the module is shaded, the entire module power output-even those sections still exposed to sunlight-is lowered.

Are there any major advances on the horizon that I should hold out for?

Advancements are happening frequently but all of these are a long way from being affordable.  Once those advancements do become affordable, the Ontario government will simply drop the price they pay for new contracts and so your exact same roof will earn less if you wait.  Now is the time to lock in your contract at the highest rate they’ll ever be offering.

Do solar panels protect my roof?

Our solar panels will absolutely help protect your shingles. The main reasons for shingle deterioration is five things, sunlight, wind, humidity, rain & snow. The solar panels help to cover the shingles and keep a lot of the elements out.

How would I re-shingle my roof after the solar system is installed?

If your roof needs re-shingling before install our site supervisor will let you know. Upon Approval of the IESO contract, a site supervisor would review your roof to measure and plan for the installation. At this time he will note the condition of your roof. If it is in need of major repair this will be addressed at this time.

How do I know if my roof is getting enough sunlight?

There are many factors that determine how effective your solar panels will be. The direction your home is facing, the angle and condition of your roof. As long as there are no large structures or trees blocking your roof, you should be good to go for solar!

If I do have a problem, who takes care of it, and what are the costs involved?

In the event of a problem, contact SunFlow Solar, we offer 3 year installation warranty. After the 3 year installation warranty period has passed it then falls to the manufacturer warranty, a 25 year warranty. 3rd party insurance warranty is added for extra protection.

Do I need to clean the snow off the panels?

Absolutely not, its not worth the risk to you or your panels. We have factored in 30 years of data, snow, rain, humidity, pollution, and most of all sunlight and daylight.

What happens if a disaster hits the panels, such as fire, tornado, hail, vandalism.

In the unfortunate event of a disaster your home insurance provider would cover the cost. This is why we encourage you to put a rider on your home insurance for your new SunFlow Solar System. Panels are designed to withstand Canadian winters including wind up to 220 Kilometers.

What happens on dark/cloudy days?

Unlike the early days of solar power when systems had to be sized for peak loads, a grid-connected PV system seamlessly switches to draw from the utility grid when needed. As such, SunFlow Solar uses an annual production target, averaging out sunnier days with cloudy days.

How long do solar panels last?

Properly installed and maintained panels will last for well over 25 years. If the system has been installed properly then there should be no problem with the system lasting over 35 years.

Can the modules withstand high winds and hail?

The panels are supported by our roofer-designed mounting system that has been tested to withstand 125 mph (200 kph) winds and can work on almost every type of roofing material. The modules we use can withstand one-inch (2.5 cm) hailstones at 50 mph (80.5 kph).
