Loop’s solar features have helped many households make an informed decision about solar panels.

Mike - "Very useful app for understanding energy usage and costs"

Very useful app which pulls together your energy usage data and costs from your supplier's energy account. We recently had a new boiler fitted and we can see month by month the improvement in efficiency and reduction in our gas bills. Looking forward to installing solar panels and we now have real data of electricity usage hour by hour which allows us to understand better how we can take advantage of a solar pv system.
Jon - "Loop app monitors insulation and prompted solar system"
Read More
We installed the Loop app to help us monitor the effect that recently installed External Wall Insulation has had on our gas usage. It was easy to set up and once we got into the colder months it was easy to see the reduction in gas usage (substantial). I then started playing with the solar simulation. The result is that we have taken out Scottish Homes Energy Support loan to install PV panels, battery and immersion heater control. The installation will take place later this year. We might have got there in the end but the Loop app gave us the confidence to go ahead as quickly as we have done. A really useful and easy to use app.
Bryan - "Solar modelling"

A great app which has allowed me to model my solar and battery usage/savings before committing. Simple to use and really helpful.
Paul - "Easy to use app with a lot of information"
Read More
Easy to use app gives great insight too energy usage. Downloaded this app as my energy supplier app is terrible. I can look at 30 minute segments to see how much energy is being used by different appliances. The solar + battery option has shown me the savings I could make by investing in solar panels. This makes it very easier to see the return on investment.
