A Grid-tie system collects sunlight through solar panels, converts it to DC (Direct Current) electricity, which then is converted to AC (Alternating Current) electricity. Then, that AC is fed directly into the Hydro Electric Grid, causing your electric meter to run backwards. During the sunny summer months, depending on your usage and the size of your system, you will accumulate credits with Hydro. In the shorter winter days, those credits will reduce your Hydro bill. These systems do not require expensive and toxic lead-acid batteries to store electricity. However, hybrid systems sometimes used in more rural areas have a small backup system to run key circuits in the event of an extended power failure and do require some battery storage.
The cost is dependent on multiple factors including: size, wattage and number of panels; Type, wattage and quality of inverter/chargers; and the options you choose.
Electricity – both AC and DC – is measured in Watts. Wattage is Volts multiplied by Amps. Most homes operate on a 120/240 Volt system. All small appliances run on 120V, while larger ones, like water heaters, stoves and system air conditioners, run on 240V.
Due to the lower cost and greater efficiency of Solar Panels and improved inverter technology, it will take less time to recoup your investment and start showing a profit. Solar Panels have a twenty-five-year warranty but typically last longer. A solar system also increases the value of your home or business.
There are many factors that impact this: Roof size and weight capacity; Southern exposure; Trees, hills and neighbouring buildings. Systems don’t have to be on rooves either, panels can be mounted on poles or on the ground or both! Contact us and we will come out for an assessment of your location.
