Solar PV Training and Employment

It would seem logical to assume that since the Solar PV industry is growing at such a robust pace, there should be plenty of jobs available. That is a correct assumption, but there is a gap between the need for workers and a well-trained work force. The old adage is; you need experience to get a job, but you can’t get experience without a job.

Fortunately, almost all prospective PV employers understand that in this industry, the training comes first, and it’s usually enough to get you started.

There is one sure way to bridge the gap between experience and employment: Training and Networking.

The first step is to get training from a recognized and competent solar training company. Be sure that it is an accredited program that will be recognized throughout the country. The second step is to get experience, and there is more than one way to get it.

  1. Find out where the solar PV contractors gather; associations are the best place to look. The American Solar Energy Society has state chapters all across the country, and most have regular meetings every month or two. It is very affordable to join an association, and the meetings are a perfect place to get to know the solar contractors and business leaders. Take the time to get your foot in the door and be willing to be time-flexible when someone      approaches you about working together – because someone probably will.
  2. If you are already in the construction industry, it is a short segue into the PV industry with proper training, and you can expand your business quickly, and with relatively little financial investment.
  3. Start your own company.  Starting any business is easier said than done, but many people do it quite successfully. If you have an entrepreneur’s spirit and the determination to get a company rolling, this is a good choice. Check the laws in your state to determine if you need to have licensing prior to installing PV systems.
  4. The “hybrid” start.  Many people intend to start their own installation companies, but want an installation or two under their belts before doing so. Working with an existing company on a project-by-project basis can help you get a little experience before you go out on your own.
  5. Install a system on your own house (or a relative’s).  You will learn just as much about installation, and you have your own PV system and some experience at the end of it.

One of the best ways to become valuable for a long-term career is to attain an industry certification. NABCEP has several certification programs; Solar PV Certified Installer, Solar Thermal Certified Installer, and Technical Sales Certification. Each of these certifications requires experience that can be obtained by either working as a self-employed, or working for a solar contractor.  Familiarize yourself with NABCEP at www.nabcep.org.

You can’t get NABCEP Certification without meeting their criteria, and no training company can certify you. The industry leaders know this, and are willing to help you (if you’re willing to help yourself) on your path to Certification. After all, with a few exceptions, they pretty much had to get their certification the same way you will. They can work with you on a “project-by-project” basis, or hire you full-time or part-time.  Each company is different, but almost all are
dedicated to the industry, have high standards, and are willing to help new installers learn.

Beware of training organizations who sell up their “Job Programs” or placement assistance. It sounds great to you before you pay your training tuition, but it’s mostly talk with very few programs actually putting people to work in the solar industry. If you find work through them, it will usually be an unpaid position as an apprentice. Don’t be sucked in to “We help you find a job.” Training companies can point you in the right direction and have contacts in the industry, but they aren’t job placement organizations.

The truth is that it takes time and dedication to retrain yourself into any industry where you are readily employable. If you want in the solar industry then be persistent and you’ll get in. Thomas Edison once said, “Many of life’s failures are people who did not realize how close they were to success when they gave up.”

Grid-tie Inverters and Generators

Grid-Tied PV Systems and Generators

The question keeps coming up; “Will a generator keep the grid interactive, non-battery based PV array operating during utility power
outages?” In theory, it seems like a logical idea since the generator operates at 240 volt 60 Hz and this is what the inverter is looking for in order to
continue operating.

The problem is, the generator cannot absorb the excess energy from the PV inverter output, nor can the generator react quickly enough
to the fluctuating output of the PV inverter. With a grid connection there is a certain amount of buoyancy or capacitance in the grid to allow for varying
electrical energy.

A second problem is how the generator will react to another AC source; it may shut down or it may be damaged by the other AC source.

The solution is the same as it has been since the start of PV energy systems, battery storage. There are many new product advancements in
battery storage or energy storage and the future looks bright. For now, the best solution for backup power during a utility outage is one of two options:

  1. An AC generator can be set up as backup power with a transfer switch that senses the loss of utility  power. If a grid interactive, non-battery based PV array is operating when utility power is down, it will go into a standby status until the utility power returns to normal.
  2. Another option is to use a battery based, grid interactive PV system that can provide backup power during utility outages; a generator can be tied in with the battery-based inverter to help charge the batteries during extended cloud cover and rainy conditions.

If option #2 is your preference, you will find that battery based inverters are quite different from utility interactive inverters. If you presently have an SMA utility interactive inverter, you can add the SMA Island battery based inverter to the system and have the best of both worlds.

For other utility, non-battery based interactive inverters, you either need to change out the inverter to one that is battery based with the utility interactive feature or just use the generator as the backup.
