That is why we created different tools to help you to be able to make more informed decisions.
All our calculators are based on industry average performance and costs as well as public data on temperatures and sunny hours.
Often, we think about the capital cost of a product and then decide if we go for it or not. So we have included in many tools how your loan repayments would change if you purchase the product as well as the estimated monthly savings. Please be aware that because we have based all calculators on averages, our calculators are a guide to help you on your way.
