We have a 4kW MASH solar system installed on our 1860s house. It isn't very noticeable on the roof so it doesn't affect the style of our home.
The MASH team and the installers were very easy to deal with. We didn't have any problems.
One of the reasons why we wanted solar is because we think we use too many fossil fuels running cars - including for our business - and we thought we could help reduce our fossil fuel consumption by installing solar panels.
We are very happy with our MASH system and pleased that it has reduced our electricity bills considerably.
