Ideally we are looking for a well-maintained roof. Solar power systems are expected to last for over 30 years and they protect the roof from getting old or weathered quickly, so it makes sense to replace an old roof or refurbish and aging one, so once the panels are installed you never have to worry about roof maintenance.
From the day the agreement is signed, the solar process typically takes a maximum of three (3) months for a residential project and up to 4-6 months for a commercial one. This allows us time to design and engineer the system, complete all required rebate and utility interconnection paperwork and obtain all permitting from the city. The actual installation crew will be physically on the site for typically 2-4 days for residential installations and 2-4 weeks for commercial solar installations, depending on the system size.
If you are a residential client, you will receive monthly statements but your actual bill will be due after 12 months. If you are a commercial customer, you will continue to receive regular bills from your utility company. However, the costs will be significantly reduced. In some cases and depending on your system size, you’ll even receive credits from the utility company for producing more energy than you consume, which later on apply towards the months when you consume more than you send back to the grid.
Solar panels will only be installed onto rooftops that are in good condition. The project manager will verify this during the site audit.. If maintenance is required after installation, the panels will have to be removed and re-installed.
American panels are always a great option, however they also tend to be more expensive. Over the course of a decade several international brands have proven to be very reliable and a great alternative to American-made panels with their high productivity and lower cost. Renesola, Canadian Solar, Hyundai and REC panels are some examples. There are also similarly priced but high wattage panels from very renowned manufacturers, such as LG. The choice pretty much depends on the home or business owner’s financial goals.
