The Path to Drawdown:        PV Solar Development

To solve climate change and remain below 1.5ºC of global warming, the globe needs to switch away from fossil fuels to using 100% emissions free sources.

The largest source of this clean energy is the sun. Photovoltaic or PV solar panels (the kind you see on rooftops) have emerged as the dominant way of capturing the sun's energy and converting it into electricity.

The industry has been growing fast and, as of 2020, solar panels are now the cheapest source of electricity in most places on earth.

Solar produces ~2% of global electricity today. According to Project Drawdown, to be on a path to remain under 1.5ºC of warming, utility scale solar will need to be generating a combined ~26% of global electricity by 2050.

To get there, the PV solar industry will need to continue to massively scale over the few next decades:

  • 720 TWh of solar electricity generated in 2019
  • 28,200 TWh needed by 2050
  • CAGR of 12.56% from 2019 - 2050

Another analysis from the IEA predicts that in order to reach a 100% clean electricity grid by 2050, annual solar panel manufacturing capacity will need to scale from 134 GWs in 2020 to 630 GWs in 2030 (p. 74).

About

iSun, Inc. (stock ticker: ISUN) is one of the largest commercial solar engineering, procurement and construction companies in the country and are expanding across the Northeastern United States. They primarily provide their services to solar energy customers for projects ranging in size from several KW for residential loads to multi-MW systems for large commercial and utility projects.

ISUN’s Role in Drawdown

iSun is a commercial solar engineering, procurement and construction company, serving customers to build solar projects ranging in scale from residential to utility. About 83% of iSun’s sales in 2020 (p. 10) were in commercial and small utility solar projects and ~0.5% were from residential installations. 

Their solar and EV hardware product line includes several creative and unique solutions like solar-powered EV charging infrastructure equipped with smart inverters and smart lighting and benches equipped with solar panels and USB mobile device charging ports.

In total, iSun has installed over 124 MW of solar systems since inception in 1988. According to the IEA, the total installed capacity of solar PV in 2020 was 737 GW (p. 198) and must increase to 14,459 GW in an energy mix that achieves net zero emissions by 2050. This means iSun’s installations accounted for 0.02% of the global solar PN market share in 2020. To maintain this position in line with IEA’s projections, iSun will need to have installed 2.43 GW by 2050.

ISUN: What We Like

iSun is setting their sights on expanding their solar operations through organic growth and acquisitions. They aim to end 2021 by installing a total of 200 MW of solar systems for industrial and municipal customers, 213 MW for asset owners and solar developers, with 5 GW of solar projects under review.

ISUN: What We Want to See Improve

Disclose GHG Emissions


As of now, iSun has no sustainability information available. As a solar company, we urge iSun to track and report their key sustainability metrics in an annual sustainability report. These metrics should include, at the very least, the company’s direct and indirect GHG emissions, emissions avoided through their projects, and energy consumption by source. These metrics will allow investors and other stakeholders to assess iSun’s carbon footprint.

Electrify The Fleet


iSun owns $1.2 million worth of vehicles (p. 39). Since there is no mention of their use of electric vehicles, we have to assume that their fleet runs entirely on fossil fuels. One very effective way to reduce iSun’s carbon footprint would be to transition to zero-emission vehicles.

Enhance Transparency Regarding Suppliers


iSun simply mentions (p. 9) that they purchase their solar panels, inverters and materials directly from multiple manufacturers and through distributors. Without further information on who these suppliers are and where they’re located, it’s impossible to evaluate iSun’s indirect emissions. We ask iSun to include more information regarding their supply chain in their reporting.
