We frequently hear from people who purchased pre-packaged renewable energy systems only to find that one part or the other was not suitable for their application. Satisfaction with your renewable energy system starts with detailed planning and ends with careful attention to your day to day power usage. In this section we are going to look at three specific areas of renewable energy use. Residential, both stand alone and grid connected, Solar Water Pumping and Telecommunications. While there is some overlap in these three types of systems, the approach to sizing them is significantly different.

Residential systems will typically have either a battery bank and inverter (stand-alone) or just an inverter to feed power into the grid (for net metering).

Solar water pumps are normally array direct, whereby the solar array is fed into a pump controller and then down to a water pump. When the sun stops shining, the pump stops running. Since there many, many different applications for water pumps and many, many different pumps to meet those various applications, we have included a questionnaire to be completed. Using that information we can help you size a pumping system to meet your needs.

Telecommunications are specific to the equipment being operated and the duty cycle of that equipment. Many telecommunications sites have equipment of different operating voltages working in tandem. This compounds the complexity of the system design. As in any solar application, the amount of sunlight available at any given time of the year is of critical importance. A system designed for a site near Phoenix won’t be adequate for a site located in Seattle. In that section you will find a questionnaire that will assist you and us in sizing a functional system to meet your telecommunications needs.
