Solar panels collect solar radiation directly from the sun, from the sky, and from sunlight reflected off the ground or area surrounding the PV panel. Orienting the PV panel in a direction and tilt to maximize its exposure to direct sunlight will optimize the collection efficiency.  Here we discuss the issues you need to consider when looking at your roof from the perspective of installing solar panels. Orientation of your roof The orientation of your roof has a significant affect on how productive your solar panels will be. You would think that having a south facing roof would produce the

That said, I’d like to explore a point

Electric cars are only increasing in popularity as more and more people are looking to reduce both their motoring costs and their environmental impact. An electric vehicle (EV) runs off a charger that can be installed in your home.  Nearly one in four of those surveyed in the National Travel Survey stated that they would be interested in buying an electric vehicle. This was due to a variety of reasons. Better affordability to run was by far the most common influencing factor at 77.8%, especially for those with Solar Panels installed,  followed by making more of a contribution to a
