Factors that Drive the Cost of a Commercial Solar System

  1. Size – Size is the most significant factor in determining the cost of any solar system. The more energy you use, the bigger your system needs to be; and a more extensive system means more equipment, which costs more.

  2. Installation – Difficulty of installation is also a factor to consider in pricing out a commercial system. Installation on a flat-top commercial roof is standard and is relatively simple. If you need a more complex installation, the price will go up.

  3. System design – Solar systems can be designed in different ways. For example, do you want a battery bank to reduce your dependence on the power grid further? This can save you more money each month, but it does increase the upfront cost.

  4. Equipment type – There’s a vast range of solar equipment out there, and the style you choose will impact the final price. For example, do you want micro-inverters on each panel or a string inverter for the whole system? Be sure to discuss not only how these choices affect the upfront price but long-term efficiency too.

  5. Available tax credits – Finally, look into available tax credits for your investment. The Federal Investment Tax Credit can offer you a credit for 30% of the cost of your system. Still, your local government may offer additional credits to reduce your overhead cost further.
