What are your options?

CAPEX (Capital Expenditure) is an option that will require your business to pay the total cost of the solar system upfront.

Power Purchase Agreement (PPA) is a fully financed on-site generation energy solution, reducing your reliance on grid-supplied energy. PPA is a great option for those who are looking to reduce their energy costs but may not have the budget to invest upfront.
