In 1839, a French physicist named Edmund Bequerel first noticed that some materialsproduce small amounts of electrical current when exposed to light. In 1905, Albert Einstein described the photovoltaic effect which is what modern solar technology is based on. The first photovoltaic panel was built in 1954 by Bell Laboratories. It was called a solar…(Read More)

        Choosing the right insulation materials and methods can greatly increase your ROI (return on investment). In this article, we’re going to cover the basic principles behind insulation. How Does it Work? To understand how insulation works, it’s best to understand how heat transfer works. Heat is transferred through three…(Read More)

We all know that solar energy systems are beneficial, but there are a few things to think about when considering a grid-connected PV (photovoltaic) system. Benefits of a Grid-Connected PV System Off-the-grid renewable energy systems are able to completely power a home. However, connecting to the power grid can offer a…(Read More)

  There is a variety of materials to choose from when updating your existing roof or installing a new one.  The material you choose will depend on several factors, including aesthetic appeal, cost, life span, and warranties. Also under consideration should be local building and fire codes and weather conditions in your area. Asphalt Shingles…(Read More)

  Attic entrances provide quick and easy access to the attic but they come with one major disadvantage. They are not usually insulated and don’t seal tightly. This directly translates into higher utility bills. Attic tents can help. It is just what the name suggests, a tent that covers your attic entrance on the…(Read More)

The solar water heater works by using the sun’s energy to heat water or a heat-transfer fluid. The solar collector and insulated storage tank make up these systems. In the case of a one-tank system, two sets of outlets and inlets circulate water through the tank and the heat transfer liquid through…(Read More)

Windows are elements of the home which often negatively impact the home’s energy efficiency. With the right windows, you can lower your utility bills, create a more comfortable atmosphere in your home, and reduce the load on your HVAC unit. Improving Existing Windows You can improve the energy efficiency of your home by making…(Read More)

Passive solar home design minimizes energy use of a home by taking advantage of a variety of factors (location, materials used, climate etc.).  When it is well designed, the energy loads needed for heating and cooling are reduced. Those needs are met, either partly or entirely, by using solar energy. Site Selection Site location should…(Read More)

There are several factors that come into consideration when planning a home solar energy system. One of the first factors involves determining whether the available amount of solar resources is enough to meet your energy generation needs (i.e. if you have enough clear access to sunlight for extended periods of time, both during the…(Read More)
