Grid-Tied or Off-Grid?
When looking to install a solar array at your home or business the first thing to consider is choosing a grid tied system or an off grid system. When looking at solar in East Tennessee, this is one of the first considerations you will need to decide.
Grid-tied Solar in East Tennessee
A grid tied system is connected to the utility power grid, so there is no loss from the system since you get paid for all the power it produces. It offers no back up power and will not provide power if utility power is down, but it is available for all federal tax incentives.
Off-grid Solar in East Tennessee
An off grid system is not tied to utility power. If batteries are fully charged you are not able to capture more power but it can be used for a back-up power source or regular peer source, and it is not available for federal tax incentives.
Roof-mount or Ground-mount?
For a flat roof, there are systems that do not penetrate the roof membrane and use a weighted ballast. For roof pitches greater than 5 degrees, there are systems that use a lag bolt attachment to roof joists. When considering roof top, you should consult with a qualified roofer to determine the condition of your roof.
A solar array will generally last 30 plus years and most roof warranties are for 10-15 years. A qualified installer can work with your roofing contractor to seal any penetration on most of the new rooftop mounting options that have integrated flashings.
For a ground mount you have to consider controlling access to the array due to DC and AV Voltages. There may be digging required for running conduit and wire from the array to an inverter depending on how far the array is from building. It may be required to dig and pour concrete from the footers to support racking.
Both roof-mount and ground-mount options have pros and cons and each installation is different.
