What is the Power Predictor?
The Power Predictor is a gadget that you attach to your roof or home if you are considering a wind turbine or solar PV install, it measures how much sun and wind it is exposed . The information is stored on a memory card and then uploaded online to be analysed. You can then find out how much potential your home or site has for renewable energy technology. It takes the guess work out of how much energy you can generate and saves making costly mistakes on under performing wind or solar PV installations. You can make better predictions on how long it will take for your installation to "pay you back" Its a complete package for analysing your home, business or site's potential to start generating electricity to feed back to the grid. If you are seriously considering investing thousands of pounds into a renewable energy system, then the power predictor is for you.

How easy is it to set up the Power Predictor?
The Power Predictor is very easy to set up and install at home or in a remote location. The instructions are simple to understand and are full of helpful diagrams to show you clearly what each bit does!
