If you are purchasing a new commercial solar power system and want it designed to include batteries, the entire cost of the new system may qualify for the ITC.  The I.R.S. has ruled that a taxpayer can claim a renewable energy tax credit to offset the cost of a battery system integrated with existing solar power equipment.  As tax regulations often change, PPM Solar strongly advises you to speak with your business’s financial advisers for tax advice before moving forward with your decision.
