Frequently Asked Questions
At Sigora Solar, we want to help you understand both the technical and practical aspects of solar power – how it works and what it can do for you.
The Q&A below does just that, providing you with some of the information you need to know as you begin thinking about converting to solar. Of course, we’re ready to answer any questions you have about the process and make sure you have the information you need to make a decision that’s best for your home or business.
So let’s start with the technical details
To say a system is “off-grid” means that it’s fully disconnected from the broader electrical grid. That’s often due to the fact that the system is positioned in a remote locations. When off-grid systems produce power during the day, they store excess power in batteries for use during the night and on cloudy days.
Then there are grid-tied systems. These types of system typically have no battery back-up. Instead, when they generate more energy than they use, they feed it back into the grid where it powers your neighbors’ home or business. This excess energy provides you with a "credit" with your utility company. During the night and on cloudy days, this credit pays for the cost of energy you do pull from the grid to power your house or business. So all the power your system generates gets used. Talk about efficiency!
Due to their excellent cost-per-kilowatt-hour performance, we generally recommend grid-tied systems. While off-grid systems may be appropriate for certain locations that lack access to power lines, the cost of the batteries generally doubles the overall cost of the system.
Understanding solar power cost and reliability
Making the most of tax credits and grants
The amount credited will be calculated by applying the current tax rate to the amount of the purchase and installation costs of the certified solar energy equipment, facilities or devices. The credit applies for five (5) years and becomes effective beginning the first day of the tax year next succeeding the certification by the division of building and life safety and will remain in effect for that tax year and the following four (4) tax years.
Example: A property is assessed at $300,000. A solar system is then installed with $10,000 of labor and purchased certified solar equipment, facilities or devices. The property’s assessed value remains $300,000.
The property owner submits the solar tax credit application and is approved. The credit amount would be equal to ($10,000 x Tax Rate) and will be applied every year for five (5) years. With a tax rate of 0.95%, the solar tax credit for this property would be: $10,000 x 0.95% = $95.00 annually ($475 in total over 5 years).
