Solar Shingle

The Future of Solar PV Shingles

Solar shingles seem like the most logical application for the future of solar PV systems, serving two purposes – a roof and a solar PV system – by simply integrating the shingles into photovoltaic roofing. There are problems with the solar shingle system, slowing its mainstream marketability, but may work if the following obstacles can be overcome:

(1) The cost of solar shingles is not competitive with conventional solar electric PV modules. Costs might balance with high penetration into the photovoltaic industry, but that takes time.

(2) The physical constraints of solar electric roofing shingles do not allow for custom fitting to varying roof dimensions. This is an obstacle that is difficult and expensive to overcome.

(3) The solar roofing contractor’s training is limited to the narrow market of solar shingle manufacturers. The manufacturers will not train contractors in areas where sales are not profitable, so the solar shingle market restricts customers’ choices and is controlled exclusively by the manufacturer.

(4) Roof warranties can only be fulfilled by the solar roofing manufacturer and its own factory-trained solar roofers. Repairs may be delayed if there is not a trained contractor in the customer’s area. Roof damage not covered by the solar roofing manufacturer would be difficult or impossible to have repaired by conventional roofers who are not trained to work with solar shingles.

I would like to see this product succeed in the market, but no manufacturer has made a successful long-term run with residential solar roofing to date, and some who are attempting it have yet to make a profit in the photovoltaic industry.

Mainstream success of solar shingle roofing may happen, but it doesn’t appear to be coming in the near future.

Training for Changes in the Solar PV Industry

Why We Keep Up with Industry Changes

There is no argument that the only constant in the world seems to be change. This is even truer for the solar industry as changes in the solar market happen fast. The only constant appears to be the solar resource itself, our sun.

Training courses must be updated regularly to meet those industry changes and to prepare students who are either just entering the solar business or professionals who are currently working in it. Solairgen is constantly editing its courses for these changes. When necessary, we’ve been known to completely rewrite courses to address industry changes due to product innovations, code changes, regulated utility interconnection requirements, and rapid industry growth.

Here are the most recent changes to our training curriculum:

PV301 NABCEP Associate Installer Credential Exam Prep:
Recently we added a NABCEP Associate Credential exam prep course to follow our PV201 Introduction to PV Design and Installation online course.  PV301 is free to our PV201 students and costs just $185 for anyone who has not taken PV201, but has met the training prerequisite to sit for the Associate Credential exam but needs exam prep study material.

PV202 Solar PV Technical Design
Our online PV202 course now focuses on the technical design aspects of residential, commercial and energy storage systems. It is the next step for designers and installers after completing PV201.

PV210 PV Sales and Cost Analysis
We have introduced a new course, PV210 PV Sales and Cost Analysis that focuses on training students to focus on the marketing aspects of solar: identifying the solar customer and their energy needs, system costs and financing methods, the value of the investment, environmental impacts and proposal writing.

PV221 – PV224 Advanced Online Series
The advanced training workshop and advanced online series have been updated to address new solar products and changes to the NEC codes. These courses include PV221 PV System and the NEC, PV222 Interactive PV System Configuration, PV223 PV Maintenance and Troubleshooting and PV224 Energy Storage PV System Configuration.

Solar is growing faster than any other energy industry so change means growth, and we believe you will enjoy being a part of it. The changes happening today are exciting innovations that make the solar industry stronger and our training produces strong professionals in the field.
