Solar Panel Group-Buy (Solarize) Program Pricing: Guide for Town Managers

Municipalities and nonprofits throughout the country have been promoting solar adoption through programs often called Solarize, group-buy or solar cooperatives. These programs focus on selecting a single installer and negotiating discount pricing for participants. 

But how does a municipality or nonprofit ensure that the price they negotiate is a good deal for the residents or members? This is especially challenging when publicly available solar pricing data is historical and therefore not a reflection of current prices.

Equipment quality affects group buy price

Enter EnergySage, the vendor-neutral online Solar Marketplace. Since EnergySage collects thousands of quotes from installers every day, we have our finger on the pulse of the solar market! Not only do these quotes include pricing, but also the specific solar equipment (type of panels and inverters). This level of detail is crucial in structuring solar program offers since they typically include pricing options for different equipment combinations.

For example, a Solarize program could include lower cost, lower efficiency panels at a set price for all residents of a community. Sometimes additional costs for certain types of equipment, such as upgrades to higher efficiency panels, are referred to as “adders.”

Market data improves solar co-op pricing

Having all of this rich market data at our fingertips begs the question: how does the pricing in group-buy programs compare to market averages?

We compared the published prices for these programs to EnergySage data for the same equipment. The results? Pricing in these programs is similar or slightly higher than the quotes that consumers would receive through EnergySage for the same equipment package during the same timeframe.

This means that even after the administrative burden of evaluating installer program proposals and negotiating fixed pricing for residents of your town, the ultimate savings offered to participants may be small or even negative.

As it turns out, installers who know they are competing for your business on EnergySage come to the table with offers that are already discounted. The EnergySage data proves that and a recent independent report from NREL also supports this claim.

Choice bolsters program results

Furthermore, 70% of customers that go solar on EnergySage do not choose the lowest price. Instead, they’re looking for a match to their specific preferences and property. There is no one-size-fits-all solar solution.

The Solar Marketplace allows for complete customization of quotes to be tailored to the customer’s individual needs, allowing for many combinations of financing, panels, equipment and installers compared to just one base package with limited adders.

So, do municipalities and nonprofits that are offering these programs have some fiduciary responsibility to the participants to actually deliver a deal? We think so. Even if it results in more solar adoption, marketing an illusive discount is not a fair practice and does a disservice to consumers and to the solar industry as a whole. EnergySage is committed to empowering consumers through objective information and price transparency.
