FAQ
Which collector is the best va

Which collector is the best value for money?
Rather than looking at just peak efficiency levels when comparing solar collectors, cost per unit of energy produced is much more logical. For example: Although collector A may be 20% more efficient than collector B, if collector A is 30% more expensive, then in fact collector B may be a better choice, as per kWh of energy produced per day it is cheaper. When payback time is of concern, not only price per kWh of the product is important, but also of the end system. In this regard Bole solar collectors provides a fruther dvantage as Bole solar collectors are very easy to install, and that can make a huge difference in terms of total install costs.
