Green Hydrogen may be the Best Energy Future
Green Hydrogen may be the Best Energy Future Hydrogen is the most abundant element in the universe and about 11% by volume of water on earth. It is easy to isolate the hydrogen atom from water through electrolysis; this is the process of applying electrical current through water to separate oxygen from hydrogen. This occurs […]
Good Solar Production is about Current Flow
Good Solar Production is about Current Flow Believe it or not, the easy part is converting sunlight into electrical current; the hard part is making sure the current flow is unimpeded. Once we have achieved sunlight to electric energy conversion, there are many ways in which current can be restricted, diminished or interrupted. This article […]
Non-export Inverters are the Best
When we say non-export, we are referring to energy flowing in reverse at the utility meter. These inverters can function as stand-alone off-grid, stand-alone grid-backup and self-consumption. In self-consumption mode, the inverter receives solar production and home energy consumption data on a continuous basis from CT meters. The inverter is programmed to reduce or stop […]
Maximize PV System Return on Investment (ROI) without a Utility Interconnection Agreement
PV system owners only need a utility interconnection agreement if they sell power across the meter into the utility grid. When a PV system has energy storage, it is possible to consume all of the power produced on-site That reduces the electrical kWh energy otherwise purchased from the utility; consumption is reduced at the retail […]
Solar PV Maintenance and Troubleshooting
We have reworked and expanded this course to provide solar technicians with a better understanding of PV system maintenance, failure probabilities and methods of recognizing and testing failure conditions. PV223 PV Maintenance and Troubleshooting is a 9-hour course covering the following topics. General PV System and Inverter Failure modes Conductor Circuit Failure Causes PV Module […]
Solar Careers in a Solar System Near You
There is no telling how many solar jobs there are in this galaxy given the probable billions of solar systems within it, but we do know that there are quite a few in this small sector. If you are thinking that you would like to build a career in the solar industry, it is an […]
Jobs growth in the solar PV industry
As of 2024 the solar workforce in the U.S. has grown to over 280,000 full time jobs and another 90,000 part time jobs. That is an annual average grow rate of over 10% since 2010. The solar industry employs twice as many workers as the coal industry, almost five times as many as nuclear power, […]
Things You Should Look for in a Solar Training Company
More and more people are starting to look for alternative means of power for their homes and business’. Some consumers are simply tired of the rising costs of energy and wish to offset it with solar energy and some customers would like to have backup power during grid failure events. Solar PV system installation is […]
Training Support for Installation Crews
The most common training support for unexperienced new hires is on-the-job-training (OJT). This is the case for several reasons that revolve around time constraints such as ready-to-start jobs and the slow pace of training a new worker. The main problem with OJT training is safety; new works without a clear understating of the safety issue […]
Minimum Requirements of the NEC With PV Systems
Minimum Requirements of the NEC With PV Systems Don’t let the title of this blog fool you. This is not about how to get by with minimum compliance to NEC when designing and installing PV systems. It is about the dangers of choosing that minimum over safety. There are contractors who look harder at the […]
