The first time I heard of Varun Sivaram and his book Taming the Sun was about 6 months ago from a friend of mine who is a member of the Council on Foreign Relations. The second time was last week when my son’s math teacher told me about Varun and his book.

I got to do some reading and research on Varun’s views and appreciated his vision for a clean energy future.  I liked Varun’s views on energy, policy, solar energy, and innovation.

I found his views on the future growth of solar interesting. Unlike Tony Seba, he does not think solar will necessarily continue to grow exponentially.

Varun is concerned that solar might hit a ceiling just like nuclear did in late 20th century. He also has a balanced portfolio theory on energy which resonated with me.

Here are two talks that feature Varun:

Solar support as a service versus Software as a service.

There are a number of leading Solar SaaS companies emerging in the solar industry as the industry grows.  Some of these leading Saas tools and  companies are listed here on this page of SolarAcademy.

As a leading distributor of solar equipment, we (CivicSolar) interact with thousands of solar installers and developers from all 50 states and beyond.

As we define the scope and strategy around our service platform, one question that is at the forefront of our minds is how our customers like to interact with their service providers and their SaaS (Software-as-a-Service) tools.

Some solar installers prefer to build organizations that house major functions like sales & marketing, procurement, and financing in-house. Others prefer to outsource these functions to third party service providers.

The installers that build these functions in house are generally larger in headcount and revenue. And they generally sell one or two uniform solution offerings on a repeat basis. A typical such customer is a residential installer with 30+ employees.  These types of installers generally use various Software as a service tools to design and to sell their projects but also as a platform to coordinate the various functions between departments in their companies.

And then, there are thousands of installers / developers that are selling less uniform solutions. They approach each project as a unique problem.  Most commercial solar projects fall into this bucket. These companies care less about Solar as a service tools but care more about getting high quality support services (for procurement, sales, finance, design, etc.) from their vendors.

Wunder Capital founder Bryan Birsic talks about this dichotomy in minute 5:28 of this Greentech Media panel about the Platform of Solar future.

This week, the new 29 year-old youngest ever Congresswoman (D) from New York (Bronx-Queens), Alexandria Ocasio-Cortez, said “If we do not do something about climate change, the world is gonna come to end in 12 years.”

White House Press Secretary Sarah Huckabee Sanders responded to that by saying we should leave the issue of Climate Change to “an authority much higher than of us”, meaning God.

And Ocasio-Cortez replied to that with a string of tweets saying the following:

“You shouldn’t need a Bible to tell you to protect our planet, but it does anyway.”

“Genesis 1: God looked on the world & called it good not once, not twice, but seven times.
Genesis 2: God commands all people to “serve and protect” creation.
Leviticus: God mandates that not only the people, but the land that sustains them, shall be respected.”

This reminded me of a webinar we did last year for CivicSolar’s installer customers with CollectiveSun. That was the first time I heard of  “Creation Care”, a theological notion that says that humans should be stewards of the planet.  You can hear more about “Creation Care” on minute 17 of this webinar:

CollectiveSun is a partner of CivicSolar and the leading financier of solar projects for Churches and other Nonprofit organizations in the US. They are also one of the leading crowd-financing platforms that enable solar projects.

This recent report by Solar Power Rocks is a great resource in showing the state of solar in each state, in the US for 2019.

The report rates each of the 50 states based on 10 factors and then assigns an overall weighted average grade for each sate based on these factors.

1) Overall Grade
2) Renewable Portfolio Standard (RPS)
3) Solar Carve Out
4) Electricity Price
5) Net Metering
6) Interconnection
7) Solar Rebates
8) State Solar Tax Credits
9) Performance Payments
10) Sales Tax Exemption
11) Property Tax Exemption

Based on this, here are the rankings of states by grade:

A: MA, NJ, RI. MD, DC, CT, VT, NY, CO, MN

B: NH, CA, NM, OR, IL, NV, DE, HI

C: IA, ME, AZ, OH, NC, MO, PA, IN, MY, SC, FL, AK, WI, UT, VA, TX

D: MI, KS, NE, WY, WV, WA, TN

F: SD, AR, ID, KY, ND, GA, MO, OK, LA, AL

Greentech Media has been a dominant voice in the solar and advanced energy sector in the past decade, delivering renewable energy news, market analysis, and conferences that inform and connect players in the global clean tech energy market. And they were recently acquired by Wood Mackenzie, a leading research and consultancy group focusing in the energy, chemicals, renewables, metals and mining sectors.

Greentech Media recently published their 2018 Q4 US Solar Market Insight Report. You can download the executive summary here. This report forecasts a slowing growth in the US Solar market as depicted in the below chart.

They are forecasting a less than 50% growth for the next 5 years for the residential & commercial solar market in the US.  We believe that forecast is too low. We expect the market to grow at least 75% in the next 5 years.

When I tell people that I have been in the solar industry for over 9 years. They start asking me questions. The most common question I get asked is:

How long is the payback period if I put solar on my home or commercial business?

And I say, it depends. On many factors.  In a place like Hawaii where electricity is 3x more expensive than the average state and sun is plenty, your payback period might be 1-2 years. In California, where electricity is 1-2x more expensive than the average, it might be 3-5 years.

In other places it could be 5-6-7 years or even 8-12 depending on the local electricity price, local state and city incentives, and the amount of sun (in that order of importance).

The second most common question I get is:

How many years will the solar panels work for?

And the answer for that question is: 30+ years. At this point almost all solar panels come with 25 or 30 years warranties.  And most panels will last up to 40 years. Panel do suffer from degradation at the rate of about 0.5% or less per year. So after 20 years, a panel will likely produce 80-85% of the energy it produced in its 1st year.

I have had conversations with veteran solar pros who have installed panels 35+ years ago and they say their panels are still producing at 75% plus of their first year production.

Many people ask me about the current state of solar energy and its potential. I usually point them to this talk by Stanford lecturer and clean energy entrepreneur, Tony Seba.
