Practical Storage of Energy Gathered from Photovoltaic Cells

In many residential solar installations, energy storage serves as a major factor in the overall system strategy. In many installations still connected to the municipal electrical grid, consumers have the option of Net Metering. This system sends surplus solar energy gathered from the installation’s photovoltaic cells and transfers it to local power plants, where it is redistributed as needed to the rest of the power network.

In the case that inclement weather or other factors prevent the collection of sufficient solar energy for the home, energy from the grid transfers back to the home via traditional means, causing no power disruption. Annually, total inbound and outbound energy costs are calculated, and often, the consumer receives a credit for producing more energy than they consumed. For installations in off-grid situations, a typical solution is that of large, rechargeable battery systems designed to store solar energy gathered during the day for use during nighttime or when adequate sunlight is unavailable. These batteries, often referred to as “forklift batteries,” weigh several thousand kilograms and last from three to twelve years, depending on the brand and the nature of the solar installation.

While much of the research and development in solar solutions focuses on maximizing the efficiency of PV cells, there are a number of companies realizing the fact that energy collection only represents half of the equation. Efficient, low-cost storage is an essential component to the solar industry. With the advent of constantly improving technologies in this area, many more consumers may choose to go off-grid in the coming years.

Andreas Tapakoudes and QSolar: Efficiency in Manufacturing

By Andreas Tapakoudes

Under President and CEO Andreas Tapakoudes’ leadership, green energy development company QSolar has created some of the most efficient and innovative products in the industry’s history. The company made strides particularly through its manufacturing process, which eliminates much of the waste that traditional green energy companies still produce. QSolar’s photovoltaic modules, found in the Kruciwatt and Kristal lines, are developed through a highly efficient module assembly process. Photovoltaic modules are first gathered by creating a circuit of Kruciwatt solar cells that are connected with a conductive copper ribbon.

Rather than utilizing the traditional flatbed laminator, however, QSolar seals the cells through the company’s patented Spraytech79 technique, covering the cells in a durable and insulating plastic compound that protects it from various weather conditions. The Spraytech79 process is faster than the customary lamination technique as well as more cost-effective less power-intensive. The lower cost in production also allows QSolar to charge less for finished modules, making a prospective partner’s initial investment significantly lower as well.

In addition, the Spraytech79 technique does not generate any harmful greenhouse gas emissions during operation or production, making the entire manufacturing process one of the most environmentally safe of its kind. QSolar employs a quality control program for all of its production processes. The program ensures superior standards in five areas of testing: function, performance, climate, reliability, and compliance.
