Bright Saver’s plug-in balcony solar kit sells out in days

Bright Saver said its first U.S. plug-in balcony solar kit sold out within days of launch and is now taking pre-orders for an August batch. The nonprofit is also launching a $29 annual membership that cuts the kit’s price to under $300 as it pushes states to update solar rules.

Why it matters: - Bright Saver is trying to make residential solar available to renters, condo owners and apartment dwellers who often cannot install rooftop systems. - The nonprofit is pairing lower-cost hardware with advocacy, aiming to reduce electricity bills and expand access to clean energy at the same time. - The model could also build political support for changing state rules on plug-in solar.

What happened: - Bright Saver said its first plug-in balcony solar product in the U.S. sold out within days of launch. - The nonprofit is now accepting pre-orders for its next batch. - Pre-orders for the August batch are open at BrightSaver.org. - Bright Saver is also launching a membership program tied to the kit.

The details: - Bright Saver is offering the kit to members at cost for under $300. - The kit retails for $499. - Shipping to the contiguous United States is included in the member price. - Bright Saver said the kit plugs into a standard outlet. - Bright Saver said members pay $29 per year. - Membership dues fund education and advocacy around plug-in solar. - Members also get access to a members-only community of balcony solar users. - Bright Saver said it publishes a full breakdown of kit costs online, including hardware, shipping and handling, and payment processing fees. - Bright Saver plans to adjust pricing as costs change. - The nonprofit plans to use an independent accounting firm to verify annually that members pay the actual cost of the product. - Bright Saver said it is driving efforts across 35 states to modernize regulations for balcony solar. - The nonprofit said it has already helped pass laws in 9 states that make it cheaper for people to power their homes with clean energy.

Between the lines: - Balcony solar is already common in Europe, where plug-in systems give people without traditional rooftop access a way to generate their own electricity. - Bright Saver is framing the program as both a consumer savings product and a political organizing tool. - Rupert Mayer, Bright Saver co-founder, said the goal is to make solar accessible to all Americans so they can cut bills and fight climate change. - Kevin Chou, Bright Saver co-founder, said the organization is building a constituency, not just a customer base. - Cora Stryker, Bright Saver co-founder, said the nonprofit is passing savings from low hardware costs directly to consumers. - Bill McKibben, author and founder of Third Act, said the solar movement now lets more people participate.

What's next: - Bright Saver is taking orders for the August batch and will adjust pricing as its costs change. - The nonprofit will keep pushing state-level rule changes to clear the way for balcony solar. - Membership growth will determine how much political leverage Bright Saver can bring to that campaign.

The bottom line: - Bright Saver is betting that cheaper solar hardware, nonprofit pricing and grassroots advocacy can speed adoption of plug-in solar in the U.S. while expanding its political reach.
