Caterpillar, SunPower team up on CAT-branded solar


One of the biggest brands in construction just expanded its solar offerings. Caterpillar has been selling solar through its Power Systems division since teaming up with First Solar three years ago, but today announced that it is taking on a new collaboration with SunPower to offer the company’s shingled P-Series through its network.

Caterpillar will offer the P-Series – which it has dubbed the PVC395 MP – as part of the Cat Hybrid Energy Solutions suite, through its dealer network in Southeast Asia, Africa, South America and the Middle East. The company has made no mention of when these modules will be available in the United States.

The addition of the P-Series is the latest expansion of Caterpillar’s clean energy options. Caterpillar makes a microgrid controllers and monitoring solutions, bi-directional inverters and energy storage solutions.

Caterpillar touts the advantage of the P-Series, which offers greater than 19% at the module level using n-type monocrystalline silicon and what SunPower calls a “unique parallel circuit architecture”. With around 500 MW of P-Series capacity currently online and more coming in Oregon and China next year, SunPower is pumping out P-Series at the highest volume of any shingle-cell product currently on the market.

The move is another win for SunPower, which recently won an exemption from Section 201 tariffs for its IBC products. However, the company is still struggling towards profitability following a dramatic restructuring.
