Finance - Goliath Solar & Electrical


Compare green loans to fund your Installation by Goliath.

Goliath Solar and Electrical can provide its customers with Green Loan offerings from some of the best regulated finance providers in the country. A ‘Green Loan’ is simply a type of personal loan used to purchase renewable energy products like Solar and Battery’s.

Goliath has chosen to only offer regulated finance products to its customers, as these products are the most open and transparent finance options in the market. Its important to the team at Goliath that our customers looking at finance options, are complimented with a product that matches the service we provide.

Does Goliath offer Interest Free Products?

99% of the time for a business to offer an Interest Free product to a customer, the business must pay a merchant fee to the finance provider in order to eliminate the interest costs and/or the associated finance costs. In our view, this is not transparent and promotes the wrong behaviours when offering financing.

With the rapid growth of Interest Free (Buy Now Pay Later) products in the market, it has become one of the largest growing payment options for customers, but at what cost?

Below is a link to a Blog written by our General Manager (Graeme Galletly) which breaks down the true cost of Interest Free products and how these are offered in the Solar Industry.
