Frequently Asked Questions
The Safe Harbor provision allows you to lock in current tax credit rates for projects completed in future years. To qualify, you must incur at least 5% of the total project cost before the deadline.
This typically involves purchasing major equipment like solar panels and inverters, with title transferring within the required timeframe. It's the simplest and most common method for securing tax credits on larger projects with extended timelines. We can help you structure your purchase to meet Safe Harbor requirements.
Exceptional ROI: With federal tax credits, state rebates, and accelerated depreciation, typical systems pay for themselves in 5-8 years. After that, you're generating free power for decades.
Predictable Energy Costs: Lock in your energy costs and protect your business from rising utility rates. Solar provides price certainty that helps with long-term budgeting.
Marketing Advantage: Demonstrate your environmental commitment to customers and employees. Many businesses prominently feature their solar installations in marketing materials and achieve carbon neutrality.
